CHAPTER I

The Mysterious Meeting on St. Mena's Island

"We've made a proper mess of things this time!" ejaculated Ross
Trefusis--"or rather I have."

"It can't be helped," rejoined his chum, Vernon Haye.  "We've done our
level best to get her off.  How long is it before the tide floats her?"

"A matter of seven or eight hours, worse luck.  You see, it was only
half ebb when we landed."

Ross bent down to remove a streak of bluish-grey mud from his ankle.

"I wish we'd taken the rowing-boat instead of this heavy old tub," he
continued.  "We'll be pretty peckish before we get back to the Hall,
and dinner's at seven-thirty."

Vernon laughed.

"It wouldn't be the first time I've had to go without grub," he
remarked.  "If you don't mind, I don't."

"Then it's no use standing here," said Ross.  "Let's get on our shoes
and go for a stroll."

Vernon Haye was a broad-shouldered lad of fifteen, with clear-cut
features and dark hair.  His companion was of about the same age, but a
good two inches taller.  His complexion was florid, his hair of an
auburn tint that narrowly escaped coming within the category of red or
ginger.  His features were full and rounded.  In short, he was a
typical Cornish youth.

Ross's father, Admiral Paul Trefusis, lived at Killigwent Hall, a
large, rambling, sixteenth-century house, standing within a mile of the
sea on the North Cornish coast.

Both lads went to the same public school, but owing to the fact that
Vernon's father, Captain Haye, was on active service with the Grand
Fleet, young Haye was spending the summer holidays with his chum at
Killigwent Hall.

That afternoon the lads had taken a small sailing-boat and had made for
St. Mena's Island, a small rocky piece of land lying about a mile off
shore, and nearly five miles from Killigwent Cove.  The island was
roughly three-quarters of a mile in length, and four hundred yards wide
in the broadest part.  The north and west sides were precipitous, but
on the side nearest to the mainland the ground sloped gradually, and
was indented by several narrow tidal coves.

The glamour of romance lay thickly around that rocky pile.  Centuries
ago it was the abode of a hermit, who, amongst his various self-imposed
tasks, had built a chapel on the summit, from the tower of which a wood
fire was kindled nightly to warn mariners of the treacherous reefs in
the vicinity of the island.

In course of time, St. Mena's Island became the haunt of wreckers and
smugglers.  The chapel, in spite of its massive construction, fell a
victim to the ravages of wind and weather, but still served as a
convenient shelter for the lawless Cornishmen who profited by the
misfortunes of honest seamen.  Immune from interference, by reason of
the superstitious awe in which the island was held by the country-folk,
the smugglers and wreckers thrived exceedingly until late in the
eighteenth century, when stern measures were taken to suppress their
misdeeds.  From that time St. Mena's Island was deserted, except for
the casual visits of tourists and summer visitors from the neighbouring
towns of Padstow and Newquay, and countless numbers of sea-birds that
take up their abode in crannies in the almost inaccessible cliffs.

Ross Trefusis was right in taking the blame of their misfortunes upon
himself.  He knew better, but, neglecting to take ordinary precautions,
he had allowed the boat to be left high and dry by the falling tide.
Upon returning to the cove the lads had found the heavy craft lying on
its bilge in the stiff bluish clay, with a ridge of jagged rocks
cutting her off from the sea.

"Perhaps," suggested Vernon, "some other boat will put off to the
island, and we can get them to put us ashore."

"Hardly likely," was the reply.  "Anyway, we'll keep a look-out.  Which
would you prefer to do--explore the Smugglers' Cave and Dead Man's
Cave, or climb up to the ruins?"

"The ruins," decided young Haye eagerly.  "I like fooling about old
ruins, and I've already seen the caves.  Besides, we can see if there
are any boats about.  It's almost like being shipwrecked on a desert
island."

"Hard lines if we were," commented Ross.  "Suppose we take an inventory
of our possessions?  Let the see: one pocket-knife, a silver watch that
has refused duty, a notebook and pencil, and five shillings and three
halfpence.  What have you to add to the common stock?"

"A knife, a pocket compass, my watch--which does go; it's now
five-and-twenty to four--and sixteen shillings and eightpence in paper
money and hard coin."

"Not a morsel of grub between the pair of us, then," declared Ross.
"Outlook beastly unpromising.  Faced with starvation unless we make up
our minds to knock over some gulls.  They are horribly fishy to eat, I
believe, and we've nothing to make a fire."

"It makes you pine for the flesh-pots of Kllligwent Hall, old man,"
exclaimed Vernon laughingly.  "Never mind, let's make a move.  I vote
we get rid of these sweaters.  It is frightfully hot."

Stripping off their woollen garments, and placing them for safety under
a gorse bush, the two lads made their way up the steep ascent to the
ruins, till, hot and well-nigh breathless in spite of being "in
training", they reached the summit of the island.

"What a jolly view!" exclaimed Vernon, turning and taking in the
panorama of rocky coast-line, an expanse of jagged, frowning, brownish
cliffs topped by the brilliant green of the Cornish moorland.

"Not bad," agreed Ross complaisantly, for the view was no stranger to
him.  "See that cliff shaped like the head and shoulders of a bearded
man?  That's Hidden Money Cove that I was speaking to you about last
night.  We'll go there next week, all being well.  You see, there's not
a sail in sight, so our chances of getting back to dinner are very
remote.  What's more, unless I'm very much mistaken, there's a
rain-storm coming.  See that dark cloud working up against the wind?"

"Yes," assented Haye.  "What of it?  A little rain won't hurt."

"It's the after effect," said Ross.  "It's quite possible it may blow
hard before night, in which case we're done for.  I've known it
impossible to approach Killigwent Cove for a week at a time."

Vernon whistled.

"Sounds lively," he remarked.

"Of course that is in the winter," his chum hastened to remind him.
"These summer gales don't last very long, but we'll be feeling precious
hungry by the time we get home, I guess."

"Look here," said Vernon after a while.  "I vote we get those sweaters.
We don't want to be soaked."

"Very well," assented Ross.  "But there's no great hurry."

Having retrieved the sweaters, the chums leisurely retraced their way
to the ruins.  For half an hour or more they wandered around the
remains, descending into the dark crypt, and running considerable risk
in climbing to the summit of the tower.  Since the spiral stone steps
had vanished long ago, the only means of getting to the top was by
climbing the gnarled stem of the ivy which grew profusely on the face
of the building.  The tower was roofless, a low, partly demolished
parapet encircling it on three sides, while a couple of weather-worn
oak-beams supporting a few planks formed a kind of platform where the
roof formerly existed.

"Think it's safe?" asked Vernon anxiously, as his chum, having got
astride the parapet, was about to lower himself upon the decrepit
woodwork.

"I've done it scores of times," said Ross confidently.  "That's right,
I'll guide your foot.  Now let go."

"By Jove!" suddenly exclaimed Haye; "there's a fellow coming towards
the ruin.  How on earth did he get here?"

"Goodness only knows," said Trefusis inconsequently.  "He may have
landed in Main Beach Cove.  Anyhow, he's at perfect liberty to do so.
I suppose he's interested in ruins."

"Let's drop a bit of stone and give him a shock when he gets here,"
suggested Vernon.  "We'll apologize afterwards.  Ten to one he'll give
us a passage back."

"I'm not so keen on dropping chunks of stone," objected Ross.  "I vote
we lie low for a bit at any rate, and see what he's up to."

"Why, do you think he's a spy?" asked his companion.  Trefusis grunted
scoffingly.

"Spy?" he repeated.  "What object would a spy have on St. Mena's
Island?  This part of Cornwall is well outside the military area.
There's nothing in the fortification line for miles.  No, it's not
that.  But _cave_, here he comes."

The lads crouched behind the crumbling parapet, and by means of
conveniently placed gaps in the masonry watched the stranger's approach.

There was nothing about the man's appearance to suggest that he was
anything but an ordinary holiday-maker.  He was slightly above average
height, rather heavily built, and inclined to flabbiness.  His
complexion was undoubtedly florid, although his face and hands were
tanned a deep brown.

He was dressed in a light-grey lounge suit, with a straw hat and brown
shoes, while in his right hand he carried a thick Malacca cane.

The exertion of climbing up the hill on which the ruined chapel stood
apparently told upon him, for he was considerably out of breath when he
passed under the ivy-clad arch.  Here he stopped to wipe his face with
a handkerchief, and while doing so dropped his cane.

It fell upon the stones with a dull thud.

At the same time the stranger gave vent to an exclamation that
certainly was not English.

The lads exchanged glances.  Here was the beginning of a mystery.  The
heaviest Malacca cane would not have made that dull metallic sound in
falling, while it was evident by the careful examination the stranger
made of the retrieved article that he was more than considerate for its
appearance.

The man made no attempt to explore the ruins.  The weather-worn fane
had no attractions for him.  It was apparently only a rendezvous, as
far as he was concerned, for at frequent intervals he would walk
stealthily through the archway, and look attentively down the hill
leading to the coves on the side facing the mainland.

It had now begun to rain--big drops that were the precursors of a heavy
shower.  The lads, in their exposed position on the tower, paid scant
heed.  Their interest and attention were centred upon the anxiously
awaiting stranger fifty feet beneath them.

Presently Ross happened to glance towards the stretch of water that
separated St. Mena's Island from the mainland.  A boat was approaching.
Already it was more than half-way across.  It was a rowing-boat,
containing only one person.  What object would anyone have in rowing
across on a wet afternoon like this? wondered the lad.

Just then the stranger began rubbing his hands with ill-concealed
satisfaction.  Although he had been frequently on the look-out, he had
evidently only just caught sight of the approaching boat.

The lads watched the little craft till it was hidden by the intervening
high ground, but already Ross felt certain that it was making for Main
Beach Cove.

There were three landing-places on St. Mena's Island--Half Tide Cove,
where the lads had left their stranded boat; Main Beach Cove, a little
to the north-east; and Deadman's Cove, farther away.  Of these, only
Main Beach was available between one hour on either side of low water.
The fact that the boat was making for it, and had already successfully
skirted the submerged reef lying off it, proved that its occupant had
local knowledge.

Some considerable time elapsed between the temporary disappearance of
the boat and the appearance of the new-comer; but at length he came
into view, walking rapidly up the steep incline without showing
anything of the physical strain that the first stranger had betrayed.

Suddenly Ross Trefusis recognized the man.  He almost felt inclined to
laugh at his suspicions.  It was Dr. Ramblethorne, the medical
practitioner at St. Bedal--a town of considerable importance about
seven miles from Killigwent Hall.  The doctor was a frequent guest of
Admiral Trefusis, and was generally considered a good, all-round
sportsman.  He was about thirty years of age, over six feet in height,
of sinewy frame and of great muscular power.  He was the wildest
motorist in that part of Cornwall, as the endorsements on his driver's
licence testified.  A keen golfer, good shot, and fisherman, he was
also a botanist; and that, perhaps, thought Ross, might account for his
presence on St. Mena's Island, although it was difficult to reconcile
the fact that Ramblethorne had an appointment with a stranger at this
desolate spot.  If a joint botanic expedition had been fixed up, why
had not the two men met on the mainland?

The unknown made no attempt to advance to meet the doctor.  Instead, he
remained within the ruins until Ramblethorne entered.

Their greeting was a surprise even to the lads, for the doctor, holding
out his hand, exclaimed in German:

"Well met, von Ruhle!  Let us hope that your arrangements will prove
satisfactory."




CHAPTER II

The Tables Turned

Both Ross Trefusis and Vernon Haye understood and could speak German.
Ross was especially good in his knowledge of the language of the modern
Hun, for in his early youth he had been inflicted with a German
governess.  Since German is one of the subjects for Sandhurst--for
which both lads were preparing--their knowledge had been considerably
improved under the cast-iron rule of a native professor.

"Eminently satisfactory," replied von Ruhle.  "We will go into details
later.  You had no difficulty in coming here, I hope?"

"None whatever."

"No suspicions?" asked von Ruhle anxiously.

Ramblethorne smiled.

"My dear von Ruhle," he replied.  "A medical practitioner is above
suspicion.  He is free to go anywhere at any hour of the day or night
without question.  No man would suspect----"

"You are clever, von Hauptwald----"

"Ssh!" interrupted the doctor.  "Call me Ramblethorne, if you please.
Of course there is no danger here, but at other times and in other
places you might incautiously give the show away.  You had a good
passage?"

"Excellent," replied von Ruhle.  "I am getting well-known to the
strafed English custom-house officers at Queenboro' and Harwich.  They
recognize me by my stick, I believe, but they little know that it is a
new one every time.  What do you think of this?  I have brought it as a
specimen for you to see.  Just fancy! every time I cross to Holland
twenty kilogrammes of good copper are on their way to the Fatherland.
By this time Herr Stabb of Essen is well acquainted with my Malacca
canes."

"A good weight to carry about," remarked Ramblethorne, wielding the
disguised bar of copper.  "I wonder you troubled."

"Mein Gott!  I could not leave it," declared von Ruhle.  "Someone might
take a fancy to it, and then the secret would be out.  But tell me:
have you succeeded in getting that commission you spoke of?"

"I am still living in hopes," replied Ramblethorne.  "Of course I could
have obtained a post of temporary surgeon in the British Navy, but it
wasn't good enough.  It's no fun running the risk of being torpedoed by
our own Submarines.  The English Army offers a wider scope.  Believe
me, I am worth more than a division to the Emperor.  I'll get a
commission, never you fear, for I have heaps of influence.  Then, of
course, I will do my utmost to fight against a terrible epidemic that
will mysteriously break out amongst the troops."

Ramblethorne, otherwise von Hauptwald, threw back his shoulders and
laughed uproariously.

"Careful!" hissed his companion.  "You will be heard over the whole
island."

"What matters?  There is not another soul in sight besides ourselves.
How much petrol have you?"

"Fifty two-gallon tins.  I expect some more by boat to-morrow.  It's
safely stored in a cave on the side of the creek.  It is a nuisance it
is raining.  I do not fancy a night's work in weather like this.
Himmel, what's that?"

Accidentally Vernon's foot had dislodged a small piece of stone.

"Nerves, my dear von Ruhle," said Ramblethorne, with his usual
good-natured smile.  "A bit of masonry has fallen from the tower.  See,
the floor is covered with similar pieces."

"If anyone should be up there----" suggested von Ruhle, pointing to the
top of the tower.

The lads could feel their hearts thumping against their ribs.  Through
a small crack in the planking they could see the eyes of the two
Germans directed upwards.

"Impossible; there are no steps," declared Ramblethorne.  "Besides,
what object would anyone have in ascending a tower on a day like this?
I fully appreciate the danger of being overheard, of course.  We've
said enough to find ourselves faced by a firing-party in the Tower of
London, my friend."

"Don't!" expostulated von Ruhle, closing his eyes as if to shut out the
unpleasant mental vision.  Then: "You have the signalling apparatus, I
hope?"

"Trust me for that, von Ruhle," replied his companion, tapping his
breast-pocket.  "All we have to do is to wait until yonder lighthouse
exposes its light.  Really the ways of these English pass
understanding.  They rigorously forbid the showing of lights in private
houses on shore, imagining that our agents would be so foolish as to
start blinking with a lamp; yet they allow these lighthouses to work as
usual, and obligingly enable us to communicate to our hearts' content."

Von Hauptwald was not far wrong in his remarks, for the instrument he
had enabled him to flash a message to a confederate without having to
be in possession of a lamp.  The flash was obtained from any distant
and visible light by means of a complicated system of mirrors.  The
reflected rays could then be projected in any desired direction so as
to be quite invisible except on a certain bearing.  It was one of the
carefully-thought-out plans adopted by the German Government to permit
its spies to communicate with their submarines without running any
great risk of detection.

"It's two hours to sunset," remarked the doctor; "three before we
commence operations.  I would suggest that we adjourn to the cave and
partake of refreshment.  You see, I have not omitted to make suitable
provision."

"Very good!" agreed von Ruhle; "but I only wish I had a waterproof.
The rain is most annoying."

Arm-in-arm the two men left the building, and presently disappeared
from view behind a slight rise in the ground.

"I say!" exclaimed Ross; "we've tumbled on something this time.  Fancy
Ramblethorne a rotten German spy.  I always thought he was a rattling
good chap."

"Evidently he isn't," rejoined Vernon.  "But the point is: what do you
propose to do?  It's beastly wet here."

"It is, now I come to think of it," agreed his chum.  "The fact is,
that until you mentioned it I was hardly aware that it was raining.
We'll discuss this knotty point."

"I vote we make tracks for the boat," suggested Haye.  "The tide must
be rising by this time.  We can then slip off and raise the alarm."

Ross shook his head.

"No go," he decided.  "We might get nabbed ourselves.  Besides, who
would be able to lay these chaps by the heels?  There's only that
motor-boat chap at Penydwick Cove, and he's precious little use.  There
are no soldiers nearer than at St. Bedal.  I propose we hang on here.
There's a snug, sheltered hole in these ruins, just big enough for us
to lie hidden.  Then we stand a good chance of hearing more of the
conversation between those beggars."

"Three hours more, remember."

"Yes, I know.  In the meanwhile we might slip down to Main Beach Cove.
There's plenty of cover amongst the rocks."

"What for?" asked Vernon.

"To see what these fellows are up to.  I'm rather anxious to renew my
slight acquaintance with friend Copperstick.  By Jove, what a cute move
to get contraband metal into Germany!"

"Not much at a time.  It shows how hard up the Germans must be for
copper when it pays a fellow to carry over about half a hundredweight
at a time."

"Well, let's get a move on," said Ross.  "Be careful how you descend.
The ivy will be fairly slippery with the wet."

Cautiously the two lads descended, reaching the ground without mishap.

"Our sweaters!" exclaimed Vernon.

"Dash it all!  Yes," agreed his companion.  "I had forgotten all about
them."

The sweaters, carefully rolled up, had been placed for security in one
corner of the chapel.  Unless anyone actually came close to the spot,
they were hidden from sight.

"Neither of those fellows stood about here, I think," remarked Ross as
the chums retrieved and donned the additional clothing.  "It's jolly
lucky, or they would have smelt a rat."

Trefusis and his companion went out into the rain, walking rapidly
towards a slight mound capped by a few irregularly shaped stones.  It
was behind this rise of ground that the two spies had gone.  Up to this
point, Ross argued, there was little need for caution; beyond, it would
be necessary to keep well under cover until they reached Main Beach.

"'Ware the skyline," cautioned Ross as the chums approached the hillock.

"Ay; 'ware the skyline," said a deep voice mockingly, "It's bad
strategy."

Turning, the lads made the disconcerting discovery that Ramblethorne
and von Ruhle were within five yards of their would-be trackers.

Ross realized that he and his chum had been badly outmanoeuvred.
Evidently the Germans suspected that they had been overheard, and
ostentatiously leaving the ruins for Main Beach Cove, they had made a
detour from the hillock, and had waited until Ross and Vernon had
emerged from the chapel.  Then, taking advantage of the wet grass that
effectually deadened the sound of their footsteps, they had turned the
tables on their shadowers.

So completely taken aback were the two lads that they stood stock-still
as if rooted to the earth.

"Not a nice evening to be out, Trefusis," continued the doctor.  "What
brings you on St. Mena's Island at this late hour of the day?"

"Our boat was left high and dry by the tide, so we had to wait and take
shelter," replied Ross.

"And so you chose a place where there was no shelter," remarked
Ramblethorne.  "Idiotic thing to do--very idiotic.  Now tell me: what
were you doing on the top of the tower?"

Ross did not hesitate in his reply.  Perhaps it would have been better
had he done so, for he had never betrayed his knowledge of German to
the doctor on any of their previous meetings, and it would have been
judicious to keep up the deception.

"What were we doing?  Listening to your precious schemes," he retorted
boldly.  "Now we know all about you, and it will be our duty to report
you as spies to the authorities.  We are expecting a search-party from
Killigwent Hall at any moment, you see."

"So that's the line of defence you propose to adopt, eh?" sneered
Ramblethorne.  "Well, look out!"

With a sudden spring the athletic man flung himself upon Ross, while
von Ruhle with equal promptitude made a rush to secure Vernon.

Strong and active though he was, Ross was no match for his huge and
powerful antagonist.  Knowing that flight was impossible, the lad
feinted, and aimed a blow with his left straight for the doctor's chin.
This Ramblethorne parried easily, and grasping the lad's wrist, held it
as in a vice, and in such a manner that rendered fruitless any attempt
on Trefusis' part to make use of his right arm.

Having thus secured his opponent, Ramblethorne watched the result of
the encounter between his fellow-spy and young Haye.

Von Ruhle had opened the attack by brandishing his heavy stick, and
calling upon Vernon to surrender.

Haye returned the compliment by closing, and dealing the German such a
terrific blow upon the chest that von Ruhle recoiled quite a couple of
yards.  The lad's onslaught had only missed the German's solar plexus
by a few inches; had it not, the chances were that von Ruhle would have
lost all interest in life for the next quarter of an hour.

But instead of following up his initial success Vernon, seeing Ross
helpless in the doctor's grip, rushed to his chum's aid.  For a few
seconds he feinted, striving to find an opening, while Ramblethorne,
dragging his captive with him, pivoted in order to keep his front
towards his new antagonist.

Those few seconds were Vernon's undoing.

Quickly recovering himself, von Ruhle sprang forward with the agility
of a panther.  The imitation Malacca cane descended with a dull thud
upon the lad's head, and like a felled ox Vernon fell inertly upon the
sodden grass.

"Hold him--so," exclaimed Ramblethorne, handing Ross over to the
custody of von Ruhle.  Then drawing a small hypodermic syringe from a
case, the former inserted the needle into the lad's forearm.

Five seconds later Ross Trefusis lay unconscious beside his companion
in misfortune.




CHAPTER III

Kidnapped

"I thought you had killed him, von Ruhle," said the doctor, bending
over Vernon and making a cursory examination of the unconscious lad.

"I thought I had," was the unconcerned reply.  "Dead men tell no tales."

"There I beg to differ," protested Ramblethorne.  "Corpses have a nasty
way of turning up at inopportune moments.  These youngsters are worth
more to us alive than dead."

"How so?"

"One is a son of Admiral Trefusis; his companion is, I believe, also a
son of a distinguished English naval officer."

"Well, and what of it?" asked von Ruhle.

"Hostages," replied the doctor briefly.  "Later I will explain.
Meanwhile we'll carry them to the cave.  It's farther than back to the
ruins; but perhaps, as young Trefusis said, there may be a
search-party, and the ruins would be one of the first objects of
investigation."

Although, with the exception of periodical visits abroad, Dr.
Ramblethorne had lived in England all his life and was a fully
qualified medical man, he was a highly trusted and talented agent of
the German Secret Service.  Months before the outbreak of war, he had
been ordered to report upon the defences of Devonport, and in order to
do this he had bought a practice on the outskirts of Plymouth.  Upon
the commencement of hostilities, he was detailed to keep under
observation the military preparations of the Duchy of Cornwall, and
also to take necessary steps for communicating with German submarines
that, under von Tirpitz's prearranged scheme, were to operate in the
Bristol Channel.  Von Ruhle was one of the few subordinates he actually
knew.  There were others with whom he communicated only through an
intermediary, and who knew him only by a number.

Von Ruhle was almost as mentally clever as his superior.
Ostentatiously he was an Englishman.  Sometimes he posed as a mining
engineer; at others as a commercial traveller; as an accredited
representative of the British Red Cross Society he was in the habit of
making frequent journeys to Holland, presumably in connection with work
at Groningen Internment Camp.  At the present time, his activities were
centred upon the formation of a secret petrol depot for the supply of
fuel to unterseebooten operating in the Bristol Channel and off the
south coast of Ireland.

A couple of slight incidents had served to put the cautious
Ramblethorne on his guard during his interview with von Ruhle in the
ruined chapel.

Although he verbally deprecated his subordinate's alarm when the lads
accidentally dislodged a stone from the tower, it was merely to disarm
possible eavesdroppers of any suspicion that their presence was
suspected.

The ability to control his feelings was one of the super-spy's chief
assets.  Suspicion once aroused, he proceeded without the faintest sign
to investigate his surroundings.  His keen eye soon lighted upon the
lads' sweaters.  Then it was that an adjournment was suggested to Main
Beach Cove.

This was simply and solely a "blind", for on gaining the cover of the
boulder-strewn hillock the doctor communicated his suspicions to his
companion.  The pair then crouched behind the rocks, whence they were
able to command a view of the tower.

It was not long before their enterprise met with success.  They saw
Trefusis and his chum cautiously descend by means of the ivy; then,
directly the lads set out upon their ill-starred tracking expedition,
the Germans, as before related, succeeded in outflanking them and
effecting their capture.

"Time!" announced Ramblethorne, consulting his watch.

"Are these safe?" asked von Ruhle, stirring Vernon's unconscious form
with his foot.

"Quite; though, perhaps, to make sure I will give this youngster a
slight injection.  Pity you hadn't held him with the double arm-lock
instead of cracking him over the head.  Herr Kapitan Schwalbe won't
want to be troubled with a passenger with a swollen head."

Leaving their senseless victims in the cave, the two Germans again
ascended the hill to St. Mena's Chapel.  As they breasted the summit,
they could see the fixed white light of Black Bull Head showing
momentarily brighter and brighter against the rapidly failing daylight.

Setting a prismatic compass in position upon the sill of one of the
glazeless windows, Ramblethorne took a careful bearing in a seaward
direction.  This done, he pointed the projector of the signalling
apparatus in precisely the same direction, and threw a waterproofed
cloth over the instrument.

"Too early yet, von Ruhle," he remarked.  "Nevertheless it is advisable
to fix our bearings while twilight lasts.  A light might spell
disaster."

"A deucedly unpleasant night for such a task," grumbled von Ruhle.

"On the contrary, it is just the very thing," replied the doctor.  "It
is not thick enough to be dangerous, but the rain is just sufficient to
assist in the screening of U75.  Do not think of your personal comfort,
my dear von Ruhle, when urgent work for the Fatherland has to be
undertaken."

For another half-hour the two men paced the grass-grown stones.  Their
choice of St. Mena's Island as a secret signalling station was an
excellent one.  It was isolated, and, being slightly greater in
elevation than the cliffs of the mainland in the immediate vicinity,
would effectually screen any ray of light sent landwards from the
expected German submarine.  Thus all danger of the narrow gleam of
reflected light being detected by the none too smart members of the
coast patrol was entirely obviated.

"Time!" exclaimed the doctor, consulting the luminous face of his watch.

Dexterously, and without disturbing the position of the instrument, von
Ruhle whipped off the covering.  Although there were no visible signs
that anything was taking place, both men knew that a beam of light,
reflected from the distant lighthouse on Black Bull Head, was being
directed seawards.

In silence the two men peered through the driving rain, von Ruhle
making use of a pair of powerful night-glasses.

Suddenly, after an interval of almost five minutes, a faint pin-prick
of light flickered from the surface of the sea.

Instantly Ramblethorne stepped a dozen paces to the right.

"I can see nothing from here," he announced in a low voice.  "Can you?"

"Yes," replied his companion.

"Good: that's friend Schwalbe."

The doctor was right.  From the deck of the unterseeboot a signalling
apparatus similar to that employed by the spies was in use.  By an
ingenious automatic arrangement it projected a beam of light, derived
from the same sources as that on St. Mena's Island, rigidly in a fixed
direction, regardless of the "lift" of the submarine under the action
of the waves.

For several minutes a rapid exchange of signals was maintained; then
the two spies, folding up their apparatus, walked rapidly towards Main
Beach Cove.

They had not long to wait before the faint sound of oars was borne to
their ears.

"Himmel!  They have arrived already," exclaimed von Ruhle.

"So it appears," replied Ramblethorne dryly.  "I pride myself that I
have exceptionally good eyesight, but I fail to see her.  The neutral
colour of the submarine is indeed excellent for night work."

They descended the sandy and shingly beach until further progress was
barred by the lapping wavelets of the rising tide.

Through the mirk loomed up the outlines of a canvas collapsible boat
crowded with men.  At two lengths from the shore the rowers laid on
their oars.  One of the men gave vent to a low whistle resembling the
call of a curlew.

"All clear," replied Ramblethorne.

The boat's keel rasped on the shingle.  A cloaked figure in the
stern-sheets made his way for'ard and leapt ashore.

"Herr von Hauptwald?" he asked.

"The same," replied the doctor.  "And Kapitan Schwalbe?"

"The captain is still on board," replied the officer.  "It is hard to
resist the opportunity of getting ashore after being cooped up there
for more than a fortnight.  But the petrol?"

"We have not so much as we hoped to obtain," replied von Ruhle.

The Leutnant muttered an oath.

"And how is business?" asked Ramblethorne, with a view of distracting
the officer's thoughts from the shortage of fuel.

The Leutnant muttered another oath.

"Bad!" he replied savagely.  "Only one wretched little tramp steamer,
which we fell in with about twenty miles from the Stacks.  She gave us
a run for our money, but we had her at last.  Even then she tried to
ram us.  One has to be most cautious also.  These accursed English have
been far too active with their new-fangled contrivances.  We called up
U71 early this morning.  She replied.  Again at noon we called her, but
there was no reply.  U70 we have lost all touch with since Monday, yet
she was under orders to assist in the blockade of the Bristol Channel
until we, as senior unterseeboot, gave instructions to return to
Wilhelmshaven."

"Lost, I suppose," remarked Ramblethorne.

The Leutnant had walked to a distance of nearly ten yards from his men,
who were drawn up in military order awaiting their officer's commands.

He lowered his voice.

"Although I am sorry to say it," he declared, "I am afraid she has gone
too.  Our losses are not only serious--they are appalling.  Submarine
work is now a continual nightmare.  We do our duty, but before long, if
we are sufficiently fortunate to escape the toils that these English
cast about us, we shall all be physical wrecks."

The man's agitation increased as he spoke.  Obviously he was labouring
under a severe strain.

"And this petrol?" he asked anxiously.  "What quantity?"

Ramblethorne told him.

"Not enough," declared the Leutnant.  "Himmel, it is not enough to get
us round Cape Wrath.  On board we have only sufficient for six hours'
surface running, while our batteries are not far short of running down.
You had better see the captain and explain."

Leaving von Ruhle to direct the seamen to the secret petrol store in
the cave, Ramblethorne accompanied the Leutnant to the submarine.

The U75 was one of the latest type of Germany's submarines.  Over three
hundred feet in length, there was little about her in common with the
accepted idea of under-water craft.  Her deck ran in one continuous
sweep for almost her entire length, and rose nearly six feet above the
surface.  The visible part of her sides was perpendicular, the bulging
sections being entirely beneath the surface.  Her conning-tower was
surrounded by a platform as long as the navigation-bridge of a modern
destroyer.  The two periscopes were "housed", but two slender
"wireless" masts gave the boat the appearance of a swift torpedo craft.

Acknowledging a salute from a burly quartermaster, Ramblethorne gained
the deck, and was escorted aft by the Leutnant.  Pacing the tapering
platform was a broad-shouldered, fair-haired man of about thirty,
although a carefully trimmed blonde beard made him look much older.

He lacked the natural elastic stride of the British naval officer.  His
movements resembled those of a thoroughly drilled soldier, yet ever and
anon he would glance furtively in the direction of the open sea as if
in constant dread of sudden and unknown peril.

"Greetings, Herr von Hauptwald!" he exclaimed, when the Leutnant had
formally introduced his visitor.  "You are well known to me by repute,
but I doubt whether we have met before."

"I fancy so," rejoined the doctor.  "Do you not remember that little
affair in the Strauer Platz?  Ah, I thought you would!  But to come to
the point.  We have been unable to obtain the requisite quantity of
petrol."

"Somehow I thought it," replied Kapitan Schwalbe.  "How much have you?"

Ramblethorne told him.

"Enough, with what we have left on board, for only eight hundred miles
run.  It will not take us home, and we are under orders not to leave
these waters before Friday next.  We have been let down badly."

"I know that it is useless to express regrets," said Ramblethorne
boldly.  "I can only hope that other means of supplying the requisite
fuel will be forthcoming.  But here is another matter.  We have had to
secure two English lads, both sons of distinguished naval officers.
Unfortunately they overheard a conversation between von Ruhle and
myself.  In the interests of the Secret Service it is absolutely
necessary that they are kept out of the way for at least a couple of
months.  I am averse to doing them personal injury."

"Then what do you wish?" asked Kapitan Schwalbe.

"Take them on board with you.  If possible, land them at a German port.
If this be possible, you will realize that we have a strong tool to
work with."

"I fail to understand," said the Kapitan of U75.

"They could be made good use of as hostages," resumed Ramblethorne.
"If these English persist in talking about reprisals, we can hint
that--well, it is unnecessary to go into details."

"I see," remarked Kapitan Schwalbe.  "But if it is impossible to land
them?"

"Then you must put them on board the first outward-bound tramp steamer
you fall in with--provided she is bound for South American ports, or
anywhere that will mean a long voyage."

"Very well," assented the submarine officer.  "I quite understand your
anxiety to get them out of the way."

"Temporarily, mind," added Ramblethorne.

"Precisely.  Herr Rix," he exclaimed, addressing the Leutnant.  "Take
four men and go ashore.  Von Ruhle will tell you where these English
boys are; have them brought on board."

"One moment," interrupted Ramblethorne.  "They came to the island in a
boat.  There is nothing unusual in that, I admit, but the fact remains
that the boat is still lying in the cove next to this.  You might order
the men to set the boat adrift."

"Water-logged, and with sails set and the main-sheet made fast.
Another deplorable accident.  Ach!  It shall be so."

Half an hour later Ross Trefusis and Vernon Haye, still unconscious
under the action of the anaesthetic injection, were brought on board
U75 and passed below.  Their boat, lying on its beam-ends, was drifting
slowly in the direction of Black Bull Head.  Ramblethorne and von
Ruhle, their work for the present done, were already on the way to the
mainland.

Meanwhile, alarmed at the non-appearance of the young heir to
Killigwent Hall and his guest, a party had set off to search St. Mena's
Island.

Just as the boat's keel grounded on the beach of Half Tide Cove, the
German submarine slipped quietly through the blurr of misty rain, and
under cover of darkness headed towards the mouth of Bristol Channel.




CHAPTER IV

The Awakening

"Dash it all!  What am I doing here?" muttered Ross Trevor drowsily, as
he opened his eyes.

For the moment he quite imagined that he was in his dormitory at
school, and that by an oversight the rest of his chums had left him in
bed.  The suggestion was strengthened by the sound of gurgling water,
as if the bathroom tap were running.  Then he became aware that
everything was pitching up and down.  Once before he had experienced a
similar sensation--when he had had a violent headache following a
slight touch of sunstroke.

It puzzled him, too, that he was almost in darkness.  Somewhere
without, and partly screened by some projection, an electric light was
burning.  The reflected rays were just sufficient to enable him to take
stock of his surroundings.

No, he was not back in the school dormitory.  True, he had a headache,
but that would not account for the actual motion.  He fumbled, his
fingers came in contact with a curved board that served to prevent the
occupant of the bed--or, rather, bunk--from falling on the floor.

Almost mechanically he rolled out, and stood supporting himself by
grasping the ledge of the bunk.  The swaying, due partly to dizziness
and partly to an unaccountable see-saw motion, would have thrown him to
the floor but for the assistance afforded by the side of the bunk.

Gradually he became aware that there was a similar sleeping-place
immediately beneath the one he had been occupying.  Someone was lying
there, breathing heavily.  There was sufficient light for Ross to
recognize him.  It was his chum Vernon.

Just then a bell clanged noisily.  The sound of running water was
outvoiced by the loud din of machinery in motion.  A wave of hot air
that reminded the lad of the atmosphere of a Tube station wafted past
him.  The whole fabric trembled under the powerful pulsations of the
mechanism.

With his legs trembling through sheer physical weakness, Ross hung on
grimly.  He wanted to shout, but no sound came from his parched tongue.
He was bewildered.  It seemed as if he were in the throes of a terrible
nightmare, and that he would awake on finding himself falling into a
bottomless abyss.

The reflected light was obscured as a broad-shouldered man made his way
along the narrow corridor in which the bunks were placed.  As he did so
he caught sight of the lad.  Without a word he seized Ross in his arms,
not roughly, but nevertheless unceremoniously, and lifted him back into
the bunk.  There was something so peremptory in the action that Ross
lay still and closed his eyes.  All his will power seemed to have
deserted him.

"Make a dash for it, old man!" exclaimed a muffled voice that Trefusis
hardly recognized as his chum's.  "Make a dash for it.  Don't let them
collar us."

It was Vernon rambling in his sleep.  The words were sufficient to give
Ross a key to the hitherto baffling problem.

Like a flash he recalled the episode of their adventure on St. Mena's
Island.  He remembered himself being held in the grasp of the powerful
Ramblethorne until unconsciousness overcame him.  He was still a
prisoner, but with the qualifying knowledge that he was not alone.
Vernon Haye was sharing his captivity, wherever it might be.

"We're afloat then," he muttered.  "What has happened?"

Moistening his lips, Ross leant over the side of the bunk and called
his chum by name.  His voice sounded strangely unfamiliar.  He could
only just hear himself above the clamorous noise of the engines.

It was not long before another man appeared at the end of the corridor.
As he did so he switched on a lamp almost above the lad's head.  For a
few seconds Ross was temporarily blinded by the sudden transition from
artificial twilight to the intense brilliancy of electric light.

"So!  You are now awake, hein?" asked a guttural voice.  "How you vos
feel?"

"Rotten!" replied Ross emphatically.  His reply was brief and to the
point.  It summed up his sensations during the last ten minutes.

The man laughed.

"So you look.  You better soon will be.  You know where you now vos?"

"On board a ship," answered the lad.  He was still hoping against hope
that his questioner was anything but a German.  There was a small
chance that he had by some means been picked up at sea by a Dutch or a
Swedish vessel.

The man's announcement "put the lid on" that possibility.

"Sheep--goot!" he chuckled.  "German unterseeboot--vot you vos call
submarine.  No danger to you boys if you yourselves behave.  Much to
see--ach! plenty much."

The lad's eyes had now become more accustomed to the light.  He could
see that his visitor was a broad-shouldered, muscular man of average
height, florid-featured, and with light-yellow hair and a fair
moustache.  He was dressed in a uniform that was apparently a bad copy
of that worn by executive officers of the British Navy.  On the breast
of his coat he wore an Iron Cross.

"Me Hermann Rix, Ober-leutnant of unterseeboot," he announced.  "Der
Kapitan send me to see how you get better.  Goot!  I tell seaman to
bring food quick.  In one hour you go on deck.  Den you feel all well."

The German Leutnant bent and peered into the lower cot.

"Fat head," he remarked seriously.  "Bad knock, but he get well soon."

With that the officer went away, leaving the light switched on.

Scrambling out of his bunk, Ross approached his chum.  Vernon was now
sleeping quietly.  His face, however, was flushed, while it was quite
evident that he had received a fairly heavy blow across the skull, for
the top of his head was swollen to a considerable extent.

Before Ross had finished his examination a sailor entered, bearing a
tray on which were three slices of rye bread, some tinned beef, and a
bottle of Rhenish wine.

"Sprechen Sie deutsch?" he asked.

For an instant Trefusis hesitated before replying.  To profess
ignorance of the German language would be an immense advantage while on
board the submarine, provided he could control his facial expressions
and listen without betraying himself.  Then, on the other hand, he
reflected that Ramblethorne, the spy, might have been instrumental in
getting him into this predicament.  More than likely the Captain of the
submarine had been informed of the fact that his unconscious passengers
were well acquainted with the tongue-twisting language of the
Fatherland.

"Here is food for you," said the man, placing the tray on the floor.
"You had better take hold of the bottle before it upsets.  We are
rolling a bit.  When your friend open his eyes, call me.  I am in
yonder compartment.  It would be well for you to dress.  I will bring
your clothes to you very soon."

Ross made a sorry meal.  The food was not at all appetizing.  His
throat was in no condition to enable him to swallow easily.  A feeling
of nausea, due either to the motion, the hot, confined air, or the
after effects of the stupefying injection--perhaps a little of all
three--was still present.

He was actually on board a German submarine--one of Tirpitz's
twentieth-century pirates.  He racked his brains to find a reason.
With its limited accommodation an unterseeboot seemed the last type of
craft that would receive a pair of prisoners--and
non-combatants--within its steel-clad hull.  It must have been at
Ramblethorne's instigation; yet why had not the spy knocked the pair of
luckless eavesdroppers over the head and tumbled them into the sea?  It
seemed by far the easiest solution; yet, in spite of that, Ross and
Vernon were being carried to an unknown destination in one of the
"mystery-craft" of the Imperial German Navy.

The reappearance of the seaman bearing Ross's clothes cut short the
latter's unsolved meditations.  Without a word the man laid the neatly
folded garments on the bunk--a pair of flannel trousers, cricket shirt,
underclothes, and the sweater that had been the cause of the lads'
undoing; but in place of his shoes a pair of half-boots, reeking with
tallow, had been provided.

Ross proceeded to dress.  As he did so a voice that he hardly
recognized asked:

"Hulloa, Trefusis, where are we?"

It was Haye.  His companion was now awake, but hardly conscious of his
surroundings.

"Better?" asked Ross laconically.  He could not at that moment bring
himself to answer the question.

"Didn't know that I was ill," remonstrated Vernon.  Then, after a vain
attempt to raise his head--perhaps fortunately, since the bottom of
Ross's cot was within a few inches of his face--he added:

"Dash it all!  I remember.  That beastly German gave me a crack over
the head with his copper walking-stick.  Where are we?"

"In a rotten hole, old man.  We're in a German submarine, bound
goodness knows where."

"Where are my clothes?" asked Haye, this time successfully getting out
of his bunk.  "Since you have yours, there seems to be no reason why I
shouldn't have mine.  Hang it!  What's the matter with me?
Everything's spinning round like a top."

Mindful of the seaman's words, and with a docility that would have
surprised him in different circumstances, Ross staggered along the
corridor.  The passage was about thirty feet in length.  On one side
the metal wall was flat, on the other it had a pronounced curve.
Against it were six bunks arranged in pairs.  Four were used as
stowing-places for baggage, the remaining ones had been given up to the
two prisoners.  The roof was almost hidden by numerous pipes, most of
them running fore and aft, while a few branched off through the walls.
The flat bulkhead evidently formed one of the walls of the engine-room,
for, as the lad placed his hand against it to steady himself, he could
feel a distinct tremor, quite different from the vibration under his
feet.  The floor was of steel, with a raised chequer pattern in order
to give a better grip to one's feet.  At frequent intervals there were
circular places, similar to those covering the coal-shoots in the
pavement of residential thoroughfares.  Walls, ceiling, and floor were
covered with beads of moisture, but whether from condensation or
leakage Ross could not decide.

At the end of the corridor or alley-way was a steel water-tight door,
running in gun-metal grooves packed with india-rubber.  The door was
closed.

Seizing the lever that served as a handle, Trefusis tried to turn it,
but without success.  Failing that, he kicked the steelwork with his
heavy half-boots, yet no response came to his appeal.

"The fellow told me to call," he muttered airily.  "What did he want to
play the fool for?"

Retracing his steps, Ross went to the other end of the alley-way.
There was barely room to pass his companion as he did so.  The place
from which he had previously seen the reflected light was now shut off
by a door similarly constructed to the one that he had vainly attempted
to open.  He was locked in a steel tomb that was itself a metal box
within a metal box--a water-tight compartment of the submarine.

"They might just as well have switched off the light while they were
about it," he exclaimed bitterly; then at the next instant he wildly
regretted his words.  The idea of being imprisoned in that cheerless
compartment without a light of any description appalled him.

Almost frantically he returned to the door that had previously baffled
him.  As he did so he became aware that the submarine was tilting
longitudinally.  Since he was unaware of the direction of the craft,
and which was the bow or stern, he was unable to judge whether the
unterseeboot was diving, or ascending to the surface.

The incline became so great that he had to grasp the door-lever for
support.  Turning his head, he saw that Vernon was hanging on grimly to
the partition between the tiers of bunks.

Then, as the vessel regained an even keel, silently and smoothly the
door slid back in its grooves, revealing a small space barely six feet
in length and five in breadth, and separated from the rest of the
vessel by a closed water-tight panel.  Part of the compartment was
occupied by a bend, at which the seaman to whom he had previously
spoken was busily engaged in mending a rent in an oilskin coat.

"My friend is now awake," announced Ross.

The man laid aside his work.

"Good!" he replied.  "He is just in time.  I will bring him his food
and his clothes.  After that you will both go on deck for fresh air
before you are interviewed by Herr Kapitan Schwalbe.  See that door?
Beyond that you must not pass without permission.  It is forbidden.  If
you do so, you will not have another opportunity in a hurry."

"What are they going to do with us?" asked Ross.

The sailor shook his head.

"It is forbidden to ask questions," he said sternly.  "Whatever is
necessary that you should know will be told you."

He turned his back upon his questioner, signifying in a plain manner
that it was useless for Trefusis to say more.  Taking the hint the lad
returned to his chum, wondering deeply at the fate that had thrown them
into the hands of the enemy.




CHAPTER V

Aboard U75

Like Ross, Vernon Haye made a poor meal.  He had barely finished when a
petty officer appeared and curtly ordered the lads to follow him.
Since he did so in German it was fairly certain that Trefusis'
admission had been communicated to both officers and crew.

Staggering, they passed along the alley-way into a broad subdivision
that extended completely athwartships.  It was one of the two broadside
torpedo-rooms, and contained two tubes of slightly greater diameter
than the British 21-inch.  In "launching-trays" by the side of the
tubes were eight torpedoes with their deadly war-heads attached.  Both
transverse bulkheads were almost hidden by indicators, voice-tubes, and
pipes for transmitting the compressed air from the air-flasks to the
torpedo-tubes.

Passing through another water-tight door the prisoners found themselves
in yet another compartment.  On one side was an "air-lock", with its
complement of life-saving helmets; on the other was an oval-shaped door
forming means of communication with the small room built against the
curved sides of the submarine.  Ross guessed, and rightly as it
afterwards transpired, that the door led into a space that could be
flooded at will, and which in turn enabled a diver to operate from the
U-boat while submerged.

Confronting the lads was an almost perpendicular steel ladder
communicating with the conning-tower.  Their guide was about to ascend
when a stern voice exclaimed in German:

"Not that, you idiotic clodhopper!  Have you lost your reason?  The
forward hatchway, don't you know?"

"Pardon, Herr Leutnant," said the petty officer, abjectly apologetic,
and, backing down the ladder, he passed through another door entering
into an alley-way between the officers' cabins.  Here was the bowl of a
supplementary periscope, so that a vision of what was taking place
could be obtained without going into the conning-tower.

The alley-way terminated at another broadside torpedo-room, the pairs
of tubes pointing in the opposite direction to those the lads had just
seen.

Beyond were the living-quarters of the crew, kept spotlessly clean and
tidy, yet Spartan-like in their simplicity.  Two of the men were sound
asleep in their bunks.  Three more, who were playing cards at a plain
deal table, glanced up from their game as the British lads passed by;
but their interest was of brief duration, and stolidly they resumed
their play.

Stooping down to avoid a large metal trough--the "house" for the
for'ard 105-millimetre disappearing gun--Ross and his chum arrived at
the ladder by which they were to gain the open air.

The hatch-cover was thrown back.  For the first time during their
captivity they made the discovery that it was night.  Looking upwards,
they could see a rectangle of dark sky twinkling with stars that, with
the slight motion of the submarine, appeared to sway to and fro.

The cool night breeze fanned their heated foreheads as they gained the
deck.  For some time, coming suddenly from the glare of the
electrically lighted interior, their eyes were blinded.  They could see
nothing but an indistinct blurr of star-lit, gently heaving water.

Gradually the sense of vision returned.  They found themselves on the
fore-deck of the unterseeboot.  They had made up their minds to see a
turtle-back deck with a narrow level platform in the centre; instead
they found that the deck was almost flat and, in nautical parlance,
flush, save where it was broken by the elongated conning-tower topped
by the twin periscopes and slender wireless mast.

Lying on the deck in all conceivable attitudes were most of the
U-boat's crew, taking advantage of a brief spell on the surface to
breathe deeply of the ozone-laden atmosphere.

Not a light was visible on board.  Even the hatchway by which the lads
had gained the deck was constructed to trap any stray beam from the
brilliant glare below.

Miles away, and low down upon the horizon, a white light blinked
solemnly; then after a brief interval it was succeeded by a red gleam.
This in turn was followed by white again.

Trefusis, with a sailor's inborn instinct, began to count the
intervals.  Although having no means of consulting the only
time-recording watch in the possession of the two captives, he had a
fair idea of counting seconds.  At fourteen from the disappearance of
the red light the white appeared.  An almost identical space of time
occurred before the red reappeared.

"It's the Wolf Light," mentally ejaculated the lad.

His next step was to fix the bearing of the lighthouse.  This he did by
looking for the Great Bear, and then, following the Pointers, the North
Star.

"Phew!" he muttered softly.  "Nor'-nor'-west.  This brute of a
submarine is right in the chops of the Channel--the main highway for
vessels making for London and the south coast ports."

"What's that?" asked Vernon, who heard his chum speaking, but had
failed to grasp the significance of his words.

"Nothing," replied Ross almost in a whisper.  "I'll tell you later."

The cool air had revived both lads wonderfully.  They had been left to
their own devices, for the petty officer had gone aft.  Those of the
crew who were on deck seemed as apathetic as the men below concerning
the presence of the kidnapped youths.  They looked like men utterly
worn out by fatigue and nervous strain.

Grasping the flexible wire hand-rail Ross continued his survey of the
horizon, all of which was visible except a small portion obscured by
the rise of the conning-tower.  The air was remarkably clear.  Taking
into consideration the refraction of the atmosphere, the navigation
lamps of a vessel shown at twenty feet above the sea would be visible
from the low-lying deck of the submarine at a distance of six to seven
miles.

But there were no signs of any vessels in the vicinity.  The German
submarine rolled lazily in complete isolation, waiting, like a snake in
the grass, for its prey.

"Herr Kapitan would see you," exclaimed the guttural voice of the petty
officer.  "Come aft.  Remember, when you are addressed, to remove your
caps."

The man led the way, making no attempt to avoid the recumbent limbs and
bodies of the crew who impeded his passage.  Treading with discretion
Ross and Vernon followed till, after skirting the base of the
conning-tower, they found themselves in the presence of
Lieutenant-Commander Schwalbe, the Kapitan of U75.

Schwalbe was sitting in a small arm-chair which had been brought from
his cabin.  He was smoking a cigar.  At his elbow stood his satellite,
Hermann Rix, who was also smoking.  This luxury was denied the crew,
the officers being permitted to smoke only when the submarine was
running awash or resting on the surface.

[Illustration: THE INTERVIEW WITH THE GERMAN CAPTAIN (missing from
book)]

"So you have recovered from your little involuntary rest," exclaimed
Schwalbe in excellent English.  He was a remarkably good linguist, for
previous to the outbreak of the war he had been the skipper of a
North-German-Lloyd boat.  By sheer good luck he had reached a home port
the day after the momentous declaration of hostilities, having narrowly
escaped capture by a British destroyer.

Owing to the great expansion of the German submarine service, and its
equally rapid reduction at the hands of the British Navy, the supply of
specially trained officers of the Imperial Navy for this branch had run
out.  More had been transferred from the pent-up High Seas Fleet, while
others had been absorbed from the now useless German Mercantile Marine,
and hastily put through a course of instruction.  Schwalbe was one of
these, and after less than two months' hazardous work in the capacity
of Unter-leutnant found himself in command of U75, one of the "last
words" of von Tirpitz's piratical fleet.

Neither Ross nor Vernon replied.  They could form no suitable answer.
It was no doubt very considerate on the part of the Kapitan to enquire
after their healths, but somehow the lads felt that the skipper of U75
was responsible for their presence on board.

"Come, come," continued Schwalbe.  "Don't be sulky."

"We are not," expostulated Ross.

"I'm glad to hear it," rejoined the Kapitan, with a grin that had the
effect of letting his cigar fall to the deck.  He stooped to retrieve
it, but, suddenly remembering that it was beneath his dignity, changed
his mind and kicked the glowing stump on one side.  Having taken
another from a gun-metal case, he lit it with a device that merely
smouldered instead of giving a bright light.

"It is as well we understand each other," he continued.  "Do you know
why you are on board U75?"

"No, sir," replied Ross.

"Neither do I," rejoined Schwalbe with astonishing candour.  "I wish I
had not been honoured with your company."

"The remedy is in your hands then, sir," said Trefusis.  "You can land
us the next time you put in at St. Mena's Island for petrol, or else
put us on board the first fishing craft we fall in with."

"I beg to differ," was the rejoinder.  "Unfortunately you are on board,
and you must make the best of it, I understand from my friend--shall I
say Dr. Ramblethorne--that you are both very inquisitive.
Inquisitiveness is a bad trait in ones so young.  You see, it has got
you into trouble.  The doctor has strong reasons for getting me to take
care of you for some considerable time, so you will have an opportunity
of seeing how we Germans make war.  No half-measures, mark you.  It is
useless to make war with a velvet glove.  You English people call us
pirates, I believe?"

"It certainly looks like piracy when German submarines sink harmless
merchantmen without warning," declared Vernon.

"For my part I have never sent a merchant vessel to the bottom without
warning," said Schwalbe.  "As a seaman I regret having to sink any ship
of commerce.  As an officer of the German Navy I have to obey orders
unquestionably.  Nevertheless I have always given the crews of British
ships a chance of escape, and have never sunk any vessel until the men
are safely in the boats, unless she attempts to show fight or to run
away."

"Would you blame a skipper for trying to save his ship?" asked Ross.

"You do not understand," exclaimed Schwalbe.  "We are at war.  A
blockade has been declared upon the British Islands.  If, after full
warning, merchantmen persist in taking the risk, it is their look-out,
not mine.  However, to return to a more personal matter: having been
saddled with you, I must endure your presence.  You will be well fed,
as far as the resources at our command will allow.  You will be free to
go wherever you wish on board, with the exception of the conning-tower,
motor- and torpedo-rooms.  I am not ungrateful, for my brother, who had
the misfortune to be in the _Ariadne_, was captured by your fleet.  He
is being well treated somewhere in England.  Hence I give privileges to
the son of Admiral Trefusis and the son of Commander Haye so long as
they are my compulsory guests.  But bear in mind: you will be watched.
Should you commit any fault, however slight, you will pay dearly for
it.  If you are foolish enough to attempt any act of treachery, death
will be the penalty.  Have I made myself perfectly clear?"

"Yes, sir," replied both lads.

"Very well.  Is there anything you would like me to do within the
bounds of reason?"

"Could we communicate with our parents?" asked Ross.

"No," replied Schwalbe decisively.  "There are strong objections.  And,
while I am on the subject, should you fall in with the crews of
destroyed ships you are strictly forbidden to communicate with them
either by word or gesture.  That will be a punishable offence of the
second degree.  Anything more?"

"My friend has had a nasty knock on the head," said Trefusis.  "Have
you a doctor on board?"

Again Kapitan Schwalbe smiled broadly.

"No," he replied.  "There is no need.  Cases of illness must wait till
we return to port.  The only injuries we are likely to sustain would
put us beyond all medical aid.  But several of the men are fairly
skilled in rough surgery, so I will----"

"Vessel on the port bow, sir; she's showing no lights," announced a
voice.

"All hands to stations!" ordered the skipper.

"Down below with you!" hissed the petty officer, who during the
interview had stood rigidly at attention at two paces to the rear of
his charges.

Already the hitherto recumbent men were alert.  Quickly, yet in order,
they disappeared down the fore hatchway, and amongst them were Ross and
Vernon.

The officers had taken their places inside the shelter of the
conning-tower.  Everything was battened down from within, and with a
gentle purr the electric motors were set in motion, while at the same
time water ballast was admitted into the trimming-tanks.

Swift and stealthy had been their preparations, but the presence of the
submarine was betrayed by the phosphorescent swirl of the water caused
by the churning of the twin propellers as she slipped beneath the
surface.

Twenty seconds later a swift vessel that looked suspiciously like a
trawler, although her speed belied her, tore over the place where U75
had disappeared.  Bare inches only separated the top of the latter's
conning-tower from the massive keel plates of the craft that had all
but accomplished its mission.

The watch-dogs of the British Navy were at work.




CHAPTER VI

The Tramp

Like a startled hare the unterseeboot fled for shelter.  Not until she
reached a depth of fifteen fathoms did she check her diagonally
downward course.  At intervals a dull booming, audible above the rattle
of the motors, proclaimed the unpleasant fact that her antagonist was
circling around the spot marked by the phosphorescent swirl and the
iridescence of escaped oil, and was firing explosive grapnels in the
hope of ripping open the U-boat's hull.

Kapitan Schwalbe, looking very grey in the artificial light, was
standing behind the quartermaster.  His hands were clenched in
momentary apprehension.  Beads of perspiration stood out upon his
forehead.  He was experiencing a foretaste of the torment of the lost.

As a submarine officer of the Imperial German Navy he was a failure.
Only sheer luck had hitherto saved him from the fate that had overtaken
scores of his brother officers in that branch of the service.  Skilled
as he was in the handling of a huge liner, he lacked the iron nerve
that is essential to the man who has to risk his life in a steel box
that, in ninety-nine cases out of a hundred, offers no means of escape
in the event of a catastrophe.

Yet he had to do his duty, notwithstanding his utter distaste for
submarine work.  He had had no option.  The officers of the British
Navy volunteer for submarine duties; those of the German Navy are
simply told off whether they want to or not.

The nerve-racking work was beginning to tell upon him.  His orders
condemned him to a forlorn hope, for the English Channel was known to
be a death-trap for the under-sea blockaders.  The sight of a trawler
filled him with feelings akin to terror.  The possibility, nay
probability, of a merchantman carrying guns made him approach his
intended prey with the utmost caution; yet, as he had remarked to Ross
Trefusis, he had never torpedoed any vessel flying the red ensign
without giving her warning.

But it was not chivalry that prompted Schwalbe to act with
consideration.  Had he been untrammelled he would have sent his prey to
the bottom without compunction, for he had all the brutal instincts of
the kultured Hun.  It was a superstitious fear that held his
frightfulness in check--a presentiment based upon the Mosaic Law, an
eye for an eye and a tooth for a tooth.

Having placed a considerable distance between him and his attacker,
Kapitan Schwalbe ordered the electric motors to be stopped.  The
ballast tanks were "blown", and cautiously U75 rose to the surface.

It was the best course open to her.  The depth of the water was much
too great to allow her to rest on the bed of the sea.  On the other
hand, in order to keep submerged, the motors would have to be in
motion.  No one knew better than Schwalbe that the British patrol-boats
would be in a position to locate with uncanny certitude the presence of
their quarry, unless the strictest silence were maintained by the
fugitive.

So, ready to dive at the first alarm, U75 floated awash until such
times as were considered favourable for getting under way.  Decidedly
this part of the English Channel was, for the time being at least,
unhealthy; and Kapitan Schwalbe resolved to make for the Bristol
Channel, where the dangers of being destroyed by modern mosquitoes were
more remote.

Meanwhile Ross and Vernon had been sent back to the quarters in the
alley-way, by the side of the motor-room.  Not knowing the reason for
the U-boat's sudden submergence, and consequently unaware of the danger
that threatened her, they formed the erroneous impression that the
submarine was about to attack.

"The old fellow gave us a pretty straight tip," remarked Vernon, when
the chums found themselves alone.  "All the same, I vote we get out of
it at the first opportunity, favourable or otherwise."

"'Ssh," whispered Ross.  "Someone might be listening.  I don't see how
you propose to clear out, though."

"We were on deck just now."

"We were," agreed Trefusis.

"It was fairly dark.  All the men up for'ard were lying down.  It would
have been an easy matter to have dived overboard and swum for it, if we
hadn't been twenty miles or more from land."

"There was a bright look-out kept, all the same," objected Ross.  "And
I wouldn't mind saying that if the submarine were closer inshore,
getting a supply of petrol, for example, we should be closely watched.
All the same, I'm with you if we get the ghost of a chance.  But it's a
rummy affair altogether.  Fancy that chap knowing our names and the
rank of our respective fathers."

"Ramblethorne must have told him that," said Vernon.

"I suppose so; but for what reason?  By Jove, if we get out of this
mess all right, we'll have something to talk about--having been
prisoners on a German submarine!"

The lads were not allowed on deck again that night.  Acting upon Haye's
suggestion they "turned in", and slept fitfully until awakened by the
noise of the watch being relieved.

The seaman, Hans Koppe, brought them their breakfast.  The meal
consisted of fish, coffee, and the usual black bread.  By this time the
captives had practically recovered from the effects of the injection.
Haye's head was still painful, although the headache had left him.

They ate with avidity, owing possibly to the atmosphere of the confined
space, which was highly charged with oxygen.

"What is the Captain's name?" asked Ross, when the man came to remove
the breakfast things.

The sailor told him.

"Where are we now?" enquired Vernon.

The man winked solemnly.

"Afloat," he replied.  "Be content with that."

Just then there were unmistakable signs of activity on the part of the
submarine crew.  Several men hurried along the alley-way, each with a
set purpose.  They paid little heed to the Englanders as they passed.

At their heels came Herr Rix, the Leutnant of the submarine.  He was
beaming affably.

"Goot mornings!" he exclaimed.  "You come mit me, den I show you how we
blockade."

He led the way to the compartment in which the bowl of the
supplementary periscope was placed.  It was now broad daylight, and
consequently the bowl showed a distinct image.  A junior officer was
standing by, but on seeing Rix approach he saluted and moved aside.

"Look!" exclaimed the Leutnant.

Both lads peered into the bowl.  On its dull sides, an expanse of sea
and sky was portrayed.  Beyond that they could see nothing, until Rix
called their attention to a small dark object.

"Englische sheep!" he declared.  "Now you vos watch."

He touched a metal stud.  Instantly an arrangement of telescopic lenses
came into play within the tube of the periscope, with the result that a
small portion of the view was greatly magnified upon the object card.
It revealed a tramp of about nine hundred tons.  She had a single
funnel painted black, with two broad red bands; two stumpy masts, with
derricks, and a lofty bridge and chart-house abaft the funnel.  She was
wall-sided.  Her rusty hull was originally painted black.  Here and
there were squares of red lead, showing that her crew had been engaged
in trying to smarten her up before she reached port.  Aft, frayed and
dirty with the smoke that poured from her funnel, floated the red
ensign.

The submarine began to rise.  Although she tilted abruptly, the image
of the tramp steamer still remained upon the object bowl.  By an
ingenious arrangement, the lenses were constructed to compensate for
any deviation of the tube of the periscope from the vertical.  The lads
could see the bows of the U-boat shaking clear of the water, throwing
cascades of foam off on either side as the passing craft forged ahead
at at least eighteen knots.

Now, for the first time, the skipper of the tramp saw the danger.  He
was a short, thick-set man, with white hair and an iron-grey moustache,
and a face the colour of mahogany.  For an instant he grasped the
bridge-rails and looked towards the submarine, then gesticulated
violently to the man at the wheel.

The spikes ran through the helmsman's hands, as he rapidly revolved the
wheel actuating the steam steering-gear.  The tramp swung hard to port,
with the idea of baffling the momentarily expected torpedo.

Kapitan Schwalbe acted up to his principles.  In any case he was loath
to use a torpedo upon a comparatively small vessel.  In response to an
order, half a dozen of the submarine's crew swarmed on deck, three
going for'ard and three aft.  Within forty-five seconds the two
disappearing guns were raised from the water-tight "houses".

Ross, Vernon, and the German Leutnant remained gazing into the bowl of
the periscope.  The vision so absorbed the attention of the two lads
that they hardly heeded the presence of Herr Rix, who occasionally
emitted grunts of satisfaction or annoyance as the scene was enacted.

The bow gun spat viciously.  The range was but three hundred yards.
The missile passed a few feet in front of the tramp's bows, and,
throwing up a shower of spray that burst inboard on the British
vessel's fo'c'sle, ricochetted a mile or so away.

The tramp's skipper showed his mettle.  Round swung the vessel, listing
heavily as she did so.  By this time the call for more steam had been
responded to, and dense clouds of black smoke belched from her funnel,
mingled with puffs of white vapour as the siren bleated loudly for aid.

Running awash, U75 had a great advantage of speed; overtaking her prey
she was able to send half a dozen shells into the lofty target
presented as she slid by.

Holes gaped in the thin plating close to the waterline.  A shell,
passing completely through the funnel, demolished the siren.  Being
without wireless, the tramp was now without means of long-distance
signalling.

Another missile hit the chart-house and, exploding, swept the frail
structure overboard in a thousand fragments.  The old skipper, hit by a
splinter of wood, fell inertly upon the bridge; but the next instant he
staggered to his feet, bawling to the crew to get the hand-steering
gear connected.

"He's down again!" exclaimed Ross breathlessly, as the brave old man
dropped upon the shattered planking of the bridge.  "Hurrah!  He's
still alive."

The skipper had deliberately taken cover behind the slender shelter
afforded by the metal side-light boards.  By the frantic movement of
his arm, it was evident that he was exhorting his men to "stick it"
like Britons.

The hail of shells continued.  Already fire had broken out on board in
several places.  A sliver of metal sheered through the ensign staff.
Without hesitation one of the crew rushed off, retrieved the
weather-worn bunting, and made his way to the mainmast.

Slowly and deliberately he re-hoisted the ensign until it fluttered
proudly from the truck, then with apparent unconcern the man
disappeared below.

By this time the tramp was again under control, with a course shaped
for land, which lay about ten miles to the S.S.E.  It was, however, a
foregone conclusion that unless help were speedily forthcoming the
vessel was doomed.

The tramp began to heel, almost imperceptibly at first, then with
increasing speed.  She had received her _coup de grace_.

Still the engines were kept going full speed ahead.  The dauntless
skipper remained on the bridge, with a look of grim resolution on his
weather-beaten features.

Slowly the vessel's way diminished.  Her bow-wave, owing to the
gradually increasing draught, was greater, but less sharp than before.
In a few minutes the water would be pouring over her fore-deck.

Seeing that their work was completed, the pirates ceased fire, the
guns' crews standing with folded arms and stolidly watching the tramp
as she struggled in her death-throes.

Presently a vast cloud of steam issued from her engine-room.  The
inrush of water had damped her furnaces.  The engineer and firemen,
their faces black with coal-dust and streaming with moisture, hurried
on deck.

For another quarter of a mile the doomed vessel carried way, then came
to a sudden stop.  As she did so she gave a quick list to starboard,
until only a few inches of bulwark amidships showed above the waves.

Then, and only then, did the skipper give orders for the boats to be
lowered.  In an orderly manner the crew manned the falls, and the task
of abandoning the ship began.

Without undue haste, the crew dropped into the waiting boats, each man
with a bundle containing his scanty personal effects wrapped up in a
handkerchief.  The Captain was the last to leave.  He did so
reluctantly, his left hand tightly grasping the ship's papers.

Having rowed a safe distance from the foundering vessel, the men rested
on their oars, and waited in silence for the end.  It was not long in
coming.

The tramp was heeling more and more, and slightly down by the bows.
Suddenly she almost righted; then, amid a smother of foam as the
compressed air burst open her hatches, she flung her stern high in the
air.

Even then she seemed in no hurry.  The after part from the mainmast
remained in view, the now motionless propeller being well clear of the
water.

For quite a minute she remained thus, then with a quick yet almost
gentle movement slid under the waves.  The last seen of her was the
weather-worn red ensign still fluttering from the truck.

The periscope's bowl showed nothing but an expanse of sea and sky, and
the two boats rising buoyantly to the waves.

A grim chuckle brought Ross and Vernon back to their surroundings.
Herr Rix was rubbing his hands and grunting with evident satisfaction.

"Goot!" he ejaculated.  "Now, how you like dat?  Now you see how we
German make blockade, hein?"

"A brave deed," replied Ross scornfully, and, gripping Vernon by the
arm, led him back to their uncomfortable quarters in the alley-way.




CHAPTER VII

On the Bed of the Sea

For the next twenty-four hours nothing exciting occurred.  The U-boat
kept to the surface as much as possible, running under her petrol
motors at fifteen knots.  To exceed that pace would mean too great a
consumption of fuel, and already the vessel was short of petrol.

Kapitan Schwalbe was prone to act on the side of extreme caution.
Having sunk one vessel, he would not tackle another in the same
vicinity.  He invariably put at least a hundred miles between him and
the scene of his latest ignominious exploit before attempting another
act of kultur.

Three times during that twenty-four hours he dived: twice on sighting
what were unquestionably Bristol Channel pilot-boats, and on the third
occasion when a Penzance lugger under motor-power (for it was a dead
calm) crossed his track.

All this time a regular stream of shipping was passing up and down the
Bristol Channel, as unconcernedly as in the piping days of peace.  To
anyone but a bumptious German, the sight would have told its own tale;
for the British Mercantile Marine, used to danger and difficulties, was
not to be deterred by the "frightfulness" of von Tirpitz's blockade.
On the contrary, the possibility of falling in with a hostile submarine
gave an unwonted spice to the everyday routine of the toilers of the
sea.

After breakfast on the following morning Ross and Vernon were told to
go on deck.  The sea was still calm, and the submarine, now running
awash at full speed, was cleaving the water with practically dry decks.

The lads soon realized what was in progress.  A couple of miles away
was a large ocean cargo-boat, outward bound, and U75 was in pursuit.

Trefusis and his chum were not allowed for'ard, where the quick-firer
was already in position for opening fire.  They were ordered abaft the
conning-tower, the hatch of which was open.

Kapitan Schwalbe's head and shoulders could be seen projecting above
the opening.  On the raised grating surrounding the conning-tower,
stood a boyish-looking Unter-leutnant.  Hermann Rix was nowhere to be
seen.  Apparently his duties compelled him to remain below.

Presently the quick-firer barked, and a projectile struck the water
about a hundred yards from the starboard side of the pursued vessel.
With the discharge of the gun, a sailor hoisted the black cross ensign
of Germany from a small flagstaff aft, while a signal in the
International Code ordering the British vessel to heave to instantly
fluttered from the light mast immediately abaft the conning-tower.

The only response from the chase was the hoisting of the red ensign,
for previously she had shown no colours.  Slowly, defiantly, the
bunting was hauled close up, and ironically "dipped" three times.

Again and again the submarine's bow-chaser fired.  The shells were well
aimed as regards direction, but all fell short.  Imperceptibly the
merchantman had increased distance.

"Look at the fools!" Ross heard the Kapitan remark, as he kept his
binoculars focused on his intended prey.  "They are trying to snapshot
us.  Are all Englishmen so blind to peril?"

"Are you sure they haven't a couple of quick-firers mounted aft, sir?"
asked the Unter-leutnant.  "There are several men gathered round
something on the poop."

"Himmel, I hope not!" ejaculated Schwalbe.  "But no; had they any guns
they would have opened fire before now.  What is the matter with our
gun-layer?  It is about time he got a shell home."

The Unter-leutnant lowered himself on the foredeck, and shouted angrily
at the seaman whose duty it was to "lay" the bow-chasers.  The man
again bent over the sights.

This time the shell pitched ahead of the chase, but slightly to port.
Some of the spray thrown up by the projectile fell on board.

"Is that the best you can do, you brainless idiot?" shouted Schwalbe
wrathfully.  Now that he was in pursuit he was loath to be baffled, but
at the same time he realized that the submarine was using a lot of
precious fuel and a prodigious amount of ammunition without any
definite result.

In the midst of his torrent of abuse directed upon the luckless
gun-layer, Kapitan Schwalbe suddenly stopped.  Gripping the rim of the
oval hatchway he gazed, horror-stricken, at two objects bobbing in the
water directly in the path of the submarine.  Then, recovering his
voice, he shouted to the quartermaster to port helm.

The fellow obeyed promptly, but it was too late.  Practically
simultaneously, two barrels swung round and crashed alongside the
submarine's hull.

Officers and men, expecting momentarily to find themselves blown into
the air, stood stock-still.  Then, as nothing so disastrous occurred,
Schwalbe gave orders for easy astern.

The barrels, connected by a span of grass rope, had been thrown
overboard from the pursued vessel, in the hope that the submarine would
foul her propellers in the tangle of line.  Once a blade picked up that
trailing rope, the latter would coil round the boss as tightly as a
band of flexible steel.

The plan all but succeeded; only the metal guards protecting the
propellers saved them from being hopelessly jammed.  Yet the attempt
was attended with good results as far as the British ship was
concerned, for by the time U75 had lost way and had cautiously backed
away from the obstruction, the swift cargo-vessel had gained a distance
that put her beyond all chance of being overhauled.

Infuriated by his failure, Kapitan Schwalbe went aft and descended into
his cabin.  He was hardly conscious of the presence of his two
involuntary guests as he passed.  He was thinking of the fate that had
consigned him to a perilous and uncongenial task.  Without doubt the
vessel he had been pursuing was equipped with wireless, and by this
time a number of those dreaded hornets would be tearing towards the
spot.  To add to his discomfiture it was reported to him that the
reserve of fuel on board had seriously dwindled.  In order to remain
effective it was necessary that U75 should replenish her tanks before
another forty-eight hours had passed.

According to his customary tactics, Schwalbe ordered the submarine to
dive to sixty feet.  At that depth she would be safe from any
possibility of being rammed.  Provided she could avoid the under-water
obstructions with which the British naval authorities had sown the bed
of the sea at almost every point likely to be frequented by lurking
hostile submarines, she was in no actual danger.

Gaining his diminutive cabin, Schwalbe by sheer force of habit
consulted the aneroid.  The mercury was falling rapidly.  Since he last
looked, barely two hours previously, it had dropped 764 to 734
millimetres, or an inch and two-tenths.  That meant that the
anti-cyclone was rapidly breaking up, and that a severe gale was
approaching with considerable swiftness.

U75 must submerge and seek shelter.  It was impossible for her to keep
at a uniform depth unless she maintained steerage-way; that meant a
great demand upon her storage batteries.  She could not remain on the
bottom of the sea in a heavy gale, owing to the constant "pumping" or
up-and-down movements caused by the varying pressure of passing waves,
unless she sought a sheltered roadstead--and sheltered roadsteads were
generally mined, or guarded by some ingenious device that had already
accounted for several of U75's consorts.

Producing a chart of the Bristol Channel, Schwalbe unfolded and spread
it upon a table.  Then, in conjunction with a translation of the latest
British Admiralty guide to the west coast of England, he proceeded to
select what he hoped would be a snug shelter during the coming storm.

"Herr Rix!" he shouted.  "I'll make for this anchorage.  There's every
indication of a strong blow from the nor'-east."

"This" was Helwick Channel, a deep, almost blind passage between the
Glamorgan coast and an outlying submerged reef known as the East and
West Helwick.  In fine weather it was a short cut for traders plying
between Llanelly and Swansea.  In bad weather it was a place to be
avoided, as far as sailing vessels were concerned.  Sheltered by the
bold outlines of Worm's Head, it ought to prove an ideal lurking-place
until the gale had blown itself out, for there was little danger of the
place being used as an anchorage, since vessels preferred to give the
rock-bound coast a wide berth.  On this account, it was also highly
probable that the Helwick channel had not been safe-guarded by the
British naval authorities.

Just before sunset, U75, having made the passage unobserved, brought up
in twelve fathoms of water, resting evenly on the firm, hard sands at
the bottom.

Ross and his chum turned in early.  There was nothing for them to do.
They held aloof from the crew; there were no books to entertain them,
no games to amuse them.  The submarine was now motionless, sufficient
water ballast having been taken in to allow her to settle firmly upon
the bottom; but, in order to be prepared, the anchor was let go.  Thus
not the slightest movement of the hull was apparent.  The rest, after
hours of erratic movement on the oily swell, was a welcome one.

The lads had set their joint watch by the submarine's time, which,
being mid-European standard, was one hour fast of Greenwich.

For several hours they slept soundly and undisturbed.  Suddenly they
were both awakened by the muffled tramp of men in heavy sea-boots.  The
solitary light in the alley-way was switched off; the water-tight doors
were firmly closed.  Already the air in the confined space was stifling.

"What has happened?" asked Vernon anxiously, for the vessel, instead of
resting immovably upon the bed of the channel, was now rolling
sluggishly.  Yet she could not be under way, for the motors were silent.

Springing from his bunk, Ross felt for the switch of the electric
light.  It was already down, yet the flow of current was interrupted.

"Let's find out," he said.  "Come along."

The lads, before turning in, had carefully laid out their clothes, so
as to be ready to slip into them at a moment's notice, yet it was a
matter of considerable difficulty to dress in the dark.

"The door's closed," announced Ross as the lads groped their way to the
end of the alley-way.

"I believe the submarine's holed," suggested Haye.

"No; she wouldn't lift as she's doing.  Besides, the crew are moving
about.  Let's bang on the door with our boots."

For several minutes they hammered, but without result.  The air, never
very fresh, was now almost unbearable, owing to lack of ventilation.
The imprisoned youths began to get desperate.

Then, without warning, the door slid back.  The alley-way was flooded
with brilliant light.

"Make haste!" shouted a voice which the lads recognized as that of Hans
Koppe.  At the same time he grasped Ross by the shoulder and literally
dragged him across the steel threshold.  Vernon followed quickly, but
barely had he gained the compartment beyond than the massive steel door
shot back again.

"Didn't you hear the order all hands for'ard?" asked Hans, not
unkindly, for the white faces of the English lads told their own tale.

"No," replied Ross.  "Besides, we are not included in the 'hands', are
we?"

"You'll have to bear the consequences if you don't obey," rejoined
Koppe.  "I'm supposed to be looking after you, but how was I to know
you hadn't turned out?  Fortunately for you, I heard your knocking, and
asked Herr Kapitan to open the doors.  He was angry, but did so."

"What has happened then?" asked Trefusis, for the seaman seemed in a
communicative mood.

"A shift of wind.  It's blowing great guns up aloft, and there's a
terrific tumble into this channel.  We've dragged, or, rather, swung
round our anchor."

"But we are safe enough?" asked Vernon.

"Yes, safe," replied Hans.  "Too safe; we cannot break out our anchor.
They are sending a diver to see what is amiss."

Evidently the diving arrangements on board were not considered to be of
a confidential nature, for Hans led the way to the compartment under
the fore-hatch, without the lads being sent back by the significant
word "verboten".

A man was preparing for a submarine walk.  He was already dressed in an
india-rubber suit, with leaden weights attached to his chest, back, and
boots.  Two others were standing by, ready to place the helmet over his
head, when Leutnant Rix had finished giving him minute directions.

The officer spoke rapidly and in a low tone.  Ross could not catch all
he said, but the words "gefaehrliche Stroemungen" (dangerous currents)
and "Der Wendepunkt der Flut" (slack water) and "Drei Viertel funf" (a
quarter to five) occurred frequently.

Vernon glanced at his watch.  It was then a minute after four.
Apparently Rix was impressing upon the man that he must clear the
anchor at slack water, which occurred at a quarter to five.

The two attendants then proceeded to place the diver's helmet on his
head.  The lads noticed that it had neither air-tube nor telephone
wire.  Nor was there a life-line attached to his waist.  Fresh air was
obtained from a metal case strapped to his back.  The man was able to
work independently, and without having to rely upon his air supply from
the submarine.

The oval door in the diving-chamber was thrown open.  The diver
entered, and the water-tight panel was quickly replaced.  One of the
seamen thrust over a short lever, and immediately water rushed into the
small compartment.  As soon as the space was filled the diver was able
to open a similar door in the outer plating of the submarine, and thus
gain the bed of the sea.

Presently Leutnant Rix turned, and saw for the first time that Ross and
Vernon were discreetly standing in the background.

"Go away.  It is forbidden!" he shouted angrily.

They obeyed promptly, retreating to the space allotted to the crew,
since it was neither desirable nor possible to return to their bunks.

For some minutes the luckless Hans Koppe was subjected to a severe
dressing-down by his hot-headed officer, and when at length the seaman
rejoined the lads he was in no humour to resume conversation.

Slowly the minutes sped.  The submarine was still rolling sluggishly,
in spite of the fact that more water had been admitted into the ballast
tanks.

The men were talking seriously amongst themselves.  From scraps of
conversation that drifted to the lads' ears, it was evident that they
had grave doubts concerning the ability of the diver to perform his
task, and even of his chances of regaining the submarine, owing to the
violent disturbances of the water.

Presently the motion of the anchored submarine became more acute.  A
weird grating sound--the noise made by the hull rasping over the bed of
the sea--was distinctly audible.

One of the seamen produced a pocket compass.  His startled exclamation
brought other members of the crew around him.  The magnetic needle was
apparently describing a semicircle.  U75 was swinging round her anchor.

Just then a bell tinkled, and a disc oscillated on the indicator board
on the bulkhead.  Instantly the two men who had been told off as
attendants upon the diver hurried aft, while their companions crowded
expectantly around the door.

The two men came back, staggering under the weight of the diver.  They
had already removed his head-dress and leaden weights.  Water dropped
from his rubber suit.  His face was livid, his eyes wide open and
rolling.  One of his bare hands was streaked with blood that flowed
sullenly from a cut in his numbed flesh.

Kapitan Schwalbe and Leutnant Rix followed him into the crew-space.  It
was not through feelings of compassion that they had come for'ard.  It
was acute anxiety to hear the diver's report.

The luckless man was laid upon the mess-table.  His attendants divested
him of his diving-suit, and rubbed his body with rough towels.  A petty
officer poured half a glass of brandy down his throat.

"What is amiss?" Kapitan Schwalbe kept on repeating.

With a great effort the diver sat up.

"An anchor, sir," he gasped feebly.  "An anchor--an English naval
pattern one--has been dropped right over ours.  A very big one."

Then his eyes closed, and he fell back unconscious.

"Gott in Himmel!" ejaculated Rix.  "We are trapped!"




CHAPTER VIII

Balked by a Sea-plane

"How so?" demanded Kapitan Schwalbe.  "If we keep quiet, the
cruiser--for cruiser she must be, judging by the fellow's
description--will weigh and proceed."

"When she does weigh we are undone," said Rix despondently.  "We are
swinging round our anchor.  For all we know, our cable has taken a turn
round hers.  As soon as they heave up their anchor, our anchor and
cable will be brought up with it, and then the game is up.  Either the
strain will overcome our dead weight and we will be hauled to the
surface, or else they'll lower one of their brutal explosive charges."

"The situation is serious," admitted Schwalbe in a low tone, for his
Leutnant's words had produced a demoralizing effect upon the men.  "How
much cable have we inboard?"

Rix repeated the question.  A petty officer doubled forward to consult
the cable indicator.  U75's anchor, when under way, was housed in a
trough on the under side of the submarine's forefoot.  The cable was
automatically ranged in a compartment between the inner and outer
skins, the space being always filled with water.  The inboard end of
the cable was not shackled; but to prevent its being able to take
charge and run out, an indicator was placed on the bulkhead nearest to
the cable tier.  The amount of chain let go was regulated by a
compressor, which was actuated from within the hull by means of levers
and cranks, watertight glands being provided to prevent any leakage
into the interior of the submarine.

"Seventy-five fathoms," reported the petty officer.  "When we commenced
to swing we paid out the length we had taken on board when we hove
short."

"We must sacrifice the lot, Herr Rix," decided Kapitan Schwalbe.
"There is no time to lose.  Storm or no storm, we must slip and run for
it."

It was U75's only chance, but it left her with only a small stockless
kedge-anchor and chain, insufficient to withstand a heavy strain.

The compressor was released.  With a loud rumble, for every sound was
magnified within the confined space, the rest of the cable was allowed
to take charge.  It did so promptly, the end of the chain giving the
hull a defiant smack as it did so.  U75, no longer held by her anchor,
began to drift with the tide, scraping dismally over the bed of Helwich
Channel.

Schwalbe was now back at his post in the conning-tower.  He dare not
take the submarine to the surface until he had put a safe distance
between him and the anchored British warship.  Nor did he care to order
the ballast tanks to be blown.  Rather than allow the "pumping" of the
seas to hammer the submerged craft upon the hard sand, he preferred to
take the risk of letting her drag.

Fortunately the tide set evenly along the bed of the channel.  A
cross-current would have set the submarine upon the jagged rocks of the
hidden West Helwick Ridge.  Nevertheless there was always the danger of
being hurled violently against a detached rock, or of fouling a live
mine if by chance the British had laid obstructions in the channel.

Both Ross and Vernon knew the danger, but, manfully concealing their
misgivings, they watched the faces of those of the crew who were "watch
below".  Most of the men were Frisians, broad-shouldered,
blonde-featured, and generally devoid of fear.  Yet the ceaseless
strain upon the nerves had already begun to tell.  As hardy fishermen,
they would not have hesitated to launch their open boats in a storm to
go to the rescue of a hapless vessel aground on the grim sand-banks of
the Frisian shore.  As the conscript crew of the submarine, compelled
to keep within the limits of a steel box that almost momentarily
threatened to be their tomb, their natural bravery was quenched.

Many of them sat upon their lockers, stolid-faced men who had already
tasted of the bitterness of death.  Others showed unmistakable signs of
excitement, bordering on frenzy.  They dreaded their life of modern
piracy.  The idea of sinking hapless merchantmen was repugnant to them,
for they understood the brotherhood of the sea.  It would be different
if they were called upon to attack an armed British ship of war.  They
had no option but to obey their junker officers, who in turn were
compelled to accept the misguided orders of the arch-pirate, von
Tirpitz.

They were disheartened, too, for reports, in spite of the vigilance of
the officers to conceal them, had reached them of the losses inflicted
upon other unterseebooten.  Occasionally they heard of a submarine crew
being saved, but generally it was a case of total loss of all on board,
by some hitherto unknown means, at the hands of the British Navy.

A hand touched Ross lightly on the shoulder.  Turning, he saw Hans
Koppe standing in a darkened corner of the compartment.

"Can you tell me this, mein herr?" asked the seaman in a low tone.  "Is
it true that the English give no quarter to German seamen in
submarines?"

"I shouldn't think that they would refuse to do so," replied Trefusis.
"Of course, I can quite understand that an opportunity doesn't often
occur; but I've heard of several instances in which your U-boats have
surrendered, and the crews have been treated exactly the same as other
prisoners of war."

"I have heard differently," said Hans, "but I hope it's a mistake.  I
have a feeling that we won't see Wilhelmshaven again.  And I have a
wife and six children at Flensburg.  Our Kapitan, too, expects that we
might be denied quarter, because we have sunk your merchantmen.
Believe me, I regret having done so, but we have orders.  Do you know
why Kapitan Schwalbe took you on board?"

"Because a certain German agent wanted us out of the way, I suppose,"
replied Ross.

"Perhaps," admitted Hans Koppe.  "But in the event of our being
captured he thinks that his good treatment of you will be in his
favour.  We are, I do not mind telling you, in a very tight corner.
Our fuel supply is almost run out.  We cannot hope to return home by
way of the Straits of Dover.  Not one of our submarines has tried that
passage of late without meeting with disaster--at least, so I heard der
Kapitan tell der Leutnant.  Ach!  It is deplorable, this war."

The rapid ringing of a gong was the signal for the watch below to turn
out.  A peculiar hissing noise proclaimed the fact that the ballast
tanks were being emptied.  U75 no longer grated over the bottom; her
motors were running almost dead slow.

Although submerged, the submarine was "pumping" violently.  Seasoned
men were prostrate with sea-sickness.  The air, in spite of chemical
purifiers, was becoming almost intolerable.  Everything movable was
being thrown about in utter disorder, while to add to the discomfort of
the crew the covering-plates of one of the lubricating-oil tanks had
been strained, and at every jerk jets of viscous fluid would squirt
through the fracture and trickle sullenly over the floor of the
crew-space.

Since the watertight doors were still closed, Ross and Vernon were
unable to get back to their bunks.  Feeling thoroughly wretched, they
were glad to accept Hans Koppe's offer to lie down on a long locker.

At noon, U75 came to the surface.  The storm, being short forecasted,
had quickly blown itself out, but the waves still ran high.

It was a prearranged plan on the part of the three U-boats operating in
the English and Bristol Channels to communicate with each other by
wireless at noon and at midnight.  U75's wireless had a range of about
180 miles, and although it could be "jammed", the call could not be
tapped by vessels other than the one for which it was intended.  To
make doubly sure, the messages were sent in code.

For nearly ten minutes U75 "made her number" without eliciting any
reply.  Perhaps it was well that Kapitan Schwalbe did not know what had
happened to her consorts.  U74 was at that moment lying on her side at
the bottom of a Welsh harbour, her crew poisoned by the chlorine fumes
from her batteries--the result of a rash curiosity on the part of her
Lieutenant-Commander to investigate the approaches to the anchorage.
As for U77, she was flying blindly for safety, with a couple of
destroyers hard on her track, and a naval sea-plane overhead to direct
them in their search.

Foiled in her efforts to get in touch with her consorts, U75 remained
awash.  The heave of the sea made it most difficult for her to use her
periscope with certainty, for she had chosen a bad pitch on her
ascent--the furious "overfalls" or "tide-rips" to the west of Lundy
Island.

"We'll pay another visit to St. Mena's Island, Herr Rix," decided
Kapitan Schwalbe, after the two officers had discussed the sinister
matter of their futile attempt to make use of the wireless.  "To-night
at nine o'clock ought to suit.  If we cannot get von Ruhle to see our
signals--for my own part, I doubt whether he is in these parts--we'll
have to do our best to get ashore.  Meanwhile, keep a bright look-out.
If we see any likely vessel coming this way, we'll try our luck once
more."

"Message just received, mein herr," announced the wireless operator.

"From whom?" enquired Kapitan Schwalbe eagerly.  He was devoutly hoping
that either U74 or U77 had been able to "call up".

"I cannot say, sir," replied the man as he handed a code message to his
superior.

Decoded, the "wireless" was as follows:

"Station 41 to unterseebooten.  Two hundred gallons of fuel available
here.  Will be on the look-out for signals at 1 a.m."

The message was a "general call" for a secret petrol depot to any
German submarine operating in the vicinity.  Reference to the list of
stations showed that "41" was at Port Treherne, a remote cove on the
North Cornish coast about fifty miles from St. Mena's Island.

"I suppose it's safe," remarked Rix.

"With due precautions--yes," rejoined Kapitan Schwalbe.  "At any rate,
petrol we must have.  Where's the chart?  Ah, there we are!  It looks a
fairly easy place to approach, don't you think?  The only danger from a
navigation point is apparently this ledge of rocks--Lost Chance Reef,
it's called.  What unpleasant names these Englishmen give to their
coasts!"

At that moment the Unter-leutnant, who happened to be at the
conning-tower periscope, reported that a large vessel was bearing down
towards them.

Kapitan Schwalbe hurried to the conning-tower.  The object depicted was
that of a modern tank-vessel about four hundred feet in length.  She
was low in the water, showing that she was well laden.  In place of
masts she had four stumpy poles supporting derricks.  Right aft was the
single funnel.  The navigation bridge was well for'ard, connected with
another bridge just in front of the funnel by a long slender gangway.

"An oil-tank homeward bound!" exclaimed Kapitan Schwalbe.  "Just what
we want to fall in with.  All being well, there will be no necessity to
visit either Port Treherne or St. Mena's Island.  Ach!  When we have
taken what we require we will set fire to the ship, and the English
will have a splendid view of a maritime bonfire."

The crew were ordered to their stations, the ballast tanks "blown", and
U75 rose to the surface instead of "running awash", since the Kapitan
had resolved to stop the tank by gun-fire.

Even then the waves were running so high that the guns' crews were
almost constantly up to their knees in water.

Somewhat to the surprise of the submarine's officers and crew, the
tank-steamer made no attempt to escape.  The firing of a shot across
her bows and the display of the black cross ensign were enough to cause
the skipper to reverse her engines.

In less than five minutes, the oil-vessel was rolling in the trough of
the sea and drifting slowly to leeward.  Yet it was a somewhat
remarkable circumstance that no attempt was made to lower the red
ensign that was proudly displayed at the stern.

Kapitan Schwalbe, with his intimate knowledge of navigation, knew that
the only way possible to board the prize was to run to leeward of her,
and let the hull of the large vessel serve as a breakwater.  He also
knew that the submarine would have to be constantly under way during
the boarding operations, otherwise the tank-vessel, offering
considerable resistance to the wind, would drift down upon U75, whose
leeway was almost unappreciable.

"Send a boat, and lower your accommodation ladder," ordered Kapitan
Schwalbe, who, as the submarine ranged up half a cable's length to
leeward of the tank-vessel, had left the shelter of the conning-tower
and was standing on the platform in its wake.

"Aye, aye," was the prompt response.

"Board her, Herr Rix," said the Leutnant's superior officer.  "Bring
back her papers with you.  Order them to pump heavy oil both to
windward and leeward.  We will then be able to run close alongside and
receive her hoses."

A boat containing two seamen and an apprentice was lowered from the
tank's quarter and rowed to the submarine.  Into it dropped Leutnant
Rix and half a dozen armed men.  With them they took two incendiary
bombs fitted with time-fuses.

Rix smiled grimly as he gained the oil-steamer's deck.  The captain and
first mate were at the head of the accommodation ladder to receive him.
Most of the crew were already mustering on deck, each with a bundle
containing his private effects.

"You prize to German boat," announced the Leutnant.  "Make you no
trouble and we you will not harm.  First we will haf much
oil--petroleum, is it not?  Order your engineer to get steam to
donkey-engine, and your men--the--the----  Hein!  Ach, I haf it--the
hoses to get ready.  When we fill up, then twenty minutes we give you
to clear out.  You onderstan'?"

"Perfectly," replied the British skipper, a tall, raw-boned Scot, as he
eyed the podgy German Leutnant with grim contempt.  "But d'ye ken yon?"

[Illustration: "'D'YE KEN YON?' ASKED THE BRITISH SKIPPER, AS HE EYED
THE PODGY GERMAN LEUTNANT WITH CONTEMPT"]

He pointed skywards.  Less than five hundred feet up, yet sufficiently
far from the tank-vessel to enable the latter to screen her from the
unterseeboot, was a large naval sea-plane.  It was to deaden the noise
of her motors that the ship's steam-pipe was continually blowing off
steam from the time that U75 made her peremptory demand.

The eyes of the Leutnant and his six men followed the direction
indicated by the British skipper's outstretched hand.

At that instant the sea-plane was visible above the towering sides of
the British vessel.

U75 was still forging slowly ahead.  In a trice Kapitan Schwalbe
decided how to act.  Ordering the men on deck to their diving stations,
he dropped agilely into the conning-tower and gave the word for the
helm to be ported.

Thus, while the quick-firers were being housed, the submarine had drawn
close under the oil-tank's quarter.  Here she was comparatively safe
from the sea-plane, as the latter could not drop any bombs without risk
of exploding the highly inflammable cargo of the British vessel.

In ten seconds the sea-plane was over and beyond her quarry.  She had
then to turn and circle overhead, awaiting the chance of shattering her
enemy as she dived.

U75 was already disappearing beneath the waves.

She dived at a very oblique angle, steeper than she had ever done
before.

Ross and Vernon, unaware of what was taking place, thought for a moment
that the submarine was plunging headlong to the bed of the Bristol
Channel.  They had to cling desperately to the nearest object to hand
to prevent themselves from sliding violently against a transverse
bulkhead.

Even as they clung they heard two muffled detonations in quick
succession, followed by a distinct quiver of the submarine's hull--a
movement that bore a marked difference to the vibrations under the
pulsations of the motors.

The sea-plane had dropped two bombs, both of which very nearly attained
their object.

Kapitan Schwalbe did not bring the submarine to a horizontal position
until she had reached a depth of fifteen fathoms.  At that depth he was
safe, both from explosives dropped from the sea-plane and also from
observation.  The water being still agitated, made it impossible for
the observer on the biplane to follow the movements of a dark shadow
fathoms deep.  For once, the rough seas had been kind to U75; but the
fact remained that she was still badly in want of fuel, while his last
attempt had resulted in the loss of an officer and six men, who could
not well be spared.

Although the sea-plane had failed to achieve her object by pulverizing
the U-boat's hull, the moral and material result was none the less
effective.

The explosion of the bombs had started several of U75's plates.
Numerous jets of water were spurting through the seams, the inrush
requiring all the mechanical appliances at the command of the modern
pirate to keep the leaks under control, while the badly-jarred nerves
of Kapitan Schwalbe and his crew warned them of the grave risks they
ran in attempting to try conclusions with even an apparently harmless
craft displaying the Red Ensign of Britain's Mercantile Marine.




CHAPTER IX

The Landing at Port Treherne

"I wonder if they'll let us go on deck," remarked Vernon Haye.  "If so,
I vote we have a shot at getting ashore.  What sort of show is Port
Treherne?"

"I know it fairly well," replied Ross.  "It's the most forsaken crib
you are ever likely to meet along the coast.  It's a deep gully in the
cliffs.  There's only one small landing-place--a flat rock.  Years ago
there used to be a tramway down to the rock, and they shipped copper
ore by means of derricks into lighters, which were towed across in fine
weather to Swansea.  But the mine closed down, the village is now
deserted, and I don't believe there are any fishermen there.  They say
that the stream that flows into the port is still heavily charged with
mundic.  At all events the water is of a bright-red colour for several
hundred yards from shore, and no fish will stick that."

It was close on the midnight following the disastrous attempt on the
part of U75 to capture the oil-tank.  The submarine was running awash,
proceeding very slowly and cautiously towards Port Treherne--Station 41
of the secret petrol depots established by German agents along the
coast of the British Islands.

The lads had been informed of the destination of the submarine, but had
not been told why.  Nevertheless it was an easy conjecture that U75 was
going there to pick up stores that she had been unable to obtain in
sufficient quantities at St. Mena's Island.

The Unter-leutnant was in charge of the submarine.  Kapitan Schwalbe
had taken the advantage of the opportunity of a few hours' sleep.
Under-officered and undermanned, the strain on the personnel was a
severe one.  It was only on rare occasions that Schwalbe could in
future descend from his post in the conning-tower.

At midnight, according to custom, the submarine called up her consorts
by wireless.  Judging by the previous attempt it seemed a useless task,
but to the Operator's surprise he received a reply from U77, which was
then lying off the Scillies.

Kapitan Schwalbe, aroused from his sleep, eagerly awaited the decoding
of the message.  It was to the effect that the commander of U77 had
received information that H.M.S. _Tremendous_, one of the earlier
Dreadnoughts, was leaving Gibraltar for Rosyth.  The _Tremendous_, he
knew, had been engaged in the Dardanelles operations.  U77 therefore
suggested that the two unterseebooten should meet at a rendezvous off
The Lizard, and attempt a _coup de main_, the success of which would go
towards atoning for the blunders and losses sustained by the German
submarines in their endeavour to blockade the British Isles.

"Good!" exclaimed Kapitan Schwalbe.  "Tell them that I purpose to
rendezvous twenty kilometres S.W. by W. of The Lizard, on Thursday at
10 p.m.  I am now about to take in fuel.  Will communicate again at
noon to-morrow.  Ask them if they have picked up a wireless from U74."

Some time elapsed before the message could be coded by the sender and
translated by the receiving submarine.  When the reply confirming the
rendezvous was received, a message was added to the effect that U77 had
heard nothing of U74 for three days.  It was presumed, however, that
she was now on her way back to Wilhelmshaven, and was already out of
wireless range.

Kapitan Schwalbe knew better.  As senior officer of the three
submarines detached to operate in these waters, he was aware that U74
would not have left her station without orders from him.  That part of
the message had been sent merely as a "blind", so that the crews of the
remaining unterseebooten should not be discouraged.  It was safe to
conclude, decided Kapitan Schwalbe, that another of the blockaders had
gone to the bottom for the last time.

It was close on one o'clock when the "wirelessing" terminated.  U75,
which had hitherto been running awash, was now trimmed for surface work.

Most of the crew went on deck.  Amongst them were Ross and Vernon, no
one offering any objection.

The sea was no longer rough.  A long oily swell took the place of the
white-crested wave.  The night was dark.  Only a few stars were
visible.  Away to the S.E., the black outlines of the Cornish coast
reared themselves like an enormous wall against the gloomy sky.

Suddenly Vernon touched his chum's elbow, as a faint pin-prick of light
glimmered twice.  It was the shore agent's signal that the coast was
clear.

Barely carrying steerage-way, U75 stood in towards the as yet invisible
Port Treherne.  Already her crew had brought the collapsible canvas
boat from below, "man-handling" it through the fore hatch.  The men,
having opened it out and shipped the felt-lined and well-greased
rowlocks, stood by to launch it.

Gradually the towering cliffs enclosing the creek became
distinguishable against the loftier background of gaunt hills.  Into
the gap the submarine crept with the utmost caution, until it seemed as
if she were on the point of running her nose against the sheer face of
the granite wall.  The water bubbled slightly as her motors were
reversed; then, turning in her own length, she brought up, with her
bows pointing seawards.

Three of the crew grasped the canvas boat and pushed it gently into the
water on the port side.  One of them clambered in and shipped the oars
in the row-locks.

The two lads were cautiously scanning the shores of the inlet.  Ross
could sniff the unmistakable Cornish air.  The call of home seemed
irresistible.  It looked a comparatively easy matter to slip quietly
over the starboard side, and swim with noiseless strokes towards the
weed-covered rocks that showed six feet or more above the sea.  It was
half ebb-tide; there was little or no drift out of the cove.  Under the
shadow of those dark cliffs detection seemed almost impossible, unless
the submarine went to the risky expedient of switching on her
search-light.

They moved stealthily towards the light wire railing on the starboard
side just abaft the conning-tower.  Everything seemed in their favour.
Kapitan Schwalbe and the Unter-leutnant were on the navigation
platform, peering through their night-glasses towards the flat rock
that served as a landing-place.  Two of the seamen were engaged in
coiling down a hand-lead line; the rest of the men on deck were
devoting their attention to the now departing canvas boat.

"Not so fast, my friends," exclaimed a low deep voice, which the lads
recognized as that of Kapitan Schwalbe.  "Remember I have a pistol
ready to hand."

"How in the name of goodness did he know what we were up to?" thought
Ross.

The chums stood stock-still.  They felt much like children found out in
some petty escapade.

"Koppe!  Where are you?" asked the Kapitan in a loud whisper.

"Here, sir," replied the seaman.

"I hold you responsible for these Englishmen.  Now they are trying to
give us the slip.  Take them below.  But hold on.  Secure them to a
stanchion.  Chain them up, and bring me the key."

The seaman approached the lads almost apologetically, and led them to
the port side just for'ard of the conning-tower.  A light steel chain
was hitched round Ross's right ankle and Vernon's left, and deftly
padlocked round one of the uprights supporting the hand-rail.

"It is of no use trying any of your pranks here," commented Kapitan
Schwalbe, still in a low tone.  "You are only looking for trouble."

For several moments all was still, save for the screech of a benighted
gull.  Overhead a meteor passed swiftly across the sky, throwing a pale
gleam upon-the lurking submarine.

"Wer da?"

The words, although uttered in an undertone, travelled distinctly over
the placid waters of the cove.

The sailor in the boat muttered some inaudible reply.  The listeners in
the submarine could detect the sound of his oars as he laid them across
the thwarts.  Then, after further conversation, could be heard the
rumble of metal as the tins of petrol were rapidly placed in the boat.

"How many are there?" asked Kapitan Schwalbe eagerly as the men
returned with the first load.

"Forty here, Herr Kapitan.  Altogether there are over two hundred."

"Then be sharp and whip them on board.  Was there any communication for
me?"

"A bundle of English newspapers, sir, and this letter."

The man drew the documents from the inside of his jumper and passed
them to a seaman, who in turn handed them to the skipper.

"I may have to land, sir," continued the seaman.  "The rest of the cans
are in a cove at some distance from the landing-place.  Can Max go with
me to mind the boat?  There is a slight ground-swell at times, and she
might have a hole through her canvas if she is allowed to grind against
the rocks."

Receiving an affirmative reply, the man told his comrade to get on
board, and once more the boat vanished into the darkness.

Another twenty minutes elapsed, then came the sounds of muffled
footsteps, and of volatile spirit surging inside the petrol cans.  Then
one of the men must have slipped, for there was a slight scuffling,
followed by the loud crash of a can clattering over the rocks.

"'Alt!  Who goes there?" shouted a hoarse and unmistakably English
voice.

"Freund," promptly replied the German sailor.

It would have been far wiser on his part if he had waited for his
fellow-worker, the German agent, to reply, since his knowledge and
pronunciation of English were almost perfect.  But unfortunately it was
the spy who had fallen, and, half-winded by coming in contact with one
of the tins, was gasping for breath and at the same time rubbing a
barked shin.

"Not good enough for me, old sport," rejoined the challenger, and
without further ado he let loose "five rounds rapid".

A loud yell announced that one of the bullets had at least taken
effect.  It was the prostrate spy who received a dose of nickel through
the fleshy part of his thigh.

The seaman, dropping his cans, fled for his life.  Recklessly he leapt
from the landing-place into the canvas boat, which his comrade had been
keeping at oar's length from the shore.  The sudden impetus was too
much for the frail craft.  She capsized, and, being only
single-skinned, sank like a stone.

Already men, members of a picket, were hastening to the sentry's
support, their progress marked by a lantern held by a stout and sleepy
sergeant.

By this time U75 was making for the open sea.  Kapitan Schwalbe was
cursing loudly; not because the luckless agent had been hit--it was his
fault for not making sure of his ground; not so much on account of the
loss of two more men, nor of the sinking of the only boat belonging to
the submarine.  His anger was aroused at the knowledge that once again
his efforts to obtain fuel had been balked.  The quantity contained in
forty tins was a mere fraction of the amount he required in order to
carry out his ambitious programme.  Bitterly he realized that, like
those of transgressors, the ways of modern pirates are hard.




CHAPTER X

A Treacherous Plot

A ragged volley of musketry followed the departing submarine.  One
bullet mushroomed itself against the steel conning-tower; another
zipped through one of the guard-rails.  The rest either flew harmlessly
overhead or ricochetted from the surface of the placid water.

Nevertheless the firing was a signal for the crew to hasten below.
Kapitan Schwalbe and the Unter-leutnant disappeared with ignominious
speed within the conning-tower.  The men, bending low, bolted for the
fore hatch.  In twenty seconds the deck of U75 was deserted save for
Ross and Vernon, who, padlocked to the stanchion, were unable to move
six inches in either direction.  They were only partly screened by the
rise of the conning-tower.  A sharp splinter from the bullet that had
splayed against the steel wall cut cleanly through Vernon's coat sleeve
and inflicted a slight gash in the lad's forearm, yet in the excitement
he hardly noticed it.

"I say, old man," exclaimed Ross, as a wave slapping against the
submarine's bow threw a shower of spray over the two prisoners.  "What
will happen if they submerge?  It seems to me as if old Schwalbe has
forgotten us."

"He would have dived before this if he intended so doing," replied
Haye.  "Ten to one he's going to pay us out for attempting to take
French, or rather German, leave.  It's jolly cold and mighty
uncomfortable, but we'll keep a stiff upper lip and show him what we
are made of."

"With all due deference to you, old chap," rejoined Trefusis, his teeth
chattering as the keen wind played upon his saturated garments, "I
would far rather be without this badge of German kultur."  He indicated
the chain that encircled his ankle.  "I don't think that you can hold a
brief for Kapitan Schwalbe.  I am not so sure about it that he is not
going to dive."

U75 dipped as he spoke, submerging her fore deck almost to the base of
the conning-tower.  Then, with a double cascade of water pouring from
her, she shook herself free, throwing her bows high above the surface.

A man, gripping the stanchion-rail as he made his way knee-deep in
water, came towards the two prisoners.  It was Hans Koppe.  He had
obtained the Kapitan's permission to release his charges from their
uncomfortable position.

"Hold on tightly as you go aft," he cautioned.  "There is hot coffee
waiting for you below."

It was impracticable to descend by means of the fore hatch.  That means
of communication had already been closed and battened down, owing to
the constant flow of water over the bows.  Even the after hatch, in
spite of the protection afforded by the conning-tower and the raised
coaming, was admitting water into the interior of the submarine.

Cold, exhausted, and hungry, the lads were glad to be able to eat and
drink, discard their wringing-wet garments, and turn in.  Without
waking they slept solidly for ten hours.  It was one in the afternoon
when they turned out.  U75 was rounding Land's End.  She was submerged,
steering a compass course, but frequently showing her periscope to
ascertain her whereabouts.  Already the Longships Lighthouse was broad
on the port beam.

It was a tedious, discomforting run from Land's End to The Lizard.  The
Mounts Bay fishing fleets were out, a circumstance that compelled the
submarine to keep below the surface.  Kapitan Schwalbe knew that once
the alert skippers of these boats sighted even the tip of the
periscope, the news of the presence of a hostile submarine would be
quickly sent to the naval authorities at Devonport.  The necessity for
secrecy also prevented him from making use of the wireless: not that
the message would be deciphered, but because the origin of the message
could be fixed with comparative certainty by any of the British
wireless stations that "picked up" her call.

The approaches to Plymouth Sound, too, gave Kapitan Schwalbe a bad
time.  Far beyond the Eddystone, and from Looe Island to Bigbury Bay,
armed trawlers and torpedo-boats patrolled incessantly, their movements
aided by sea-planes.  It was almost a matter of impossibility for a
hostile submarine to approach Plymouth Sound by daylight, since the
aeroplanes were able to discern any sinister object moving under the
comparatively shallow and clear waters between Rame Head and Stoke
Point; while at night the precautions taken were of such an elaborate
and efficient description as to seal the fate of any submarine rash
enough to run her head into a noose.

Accordingly U75 gave the Eddystone a wide berth, shaping a course to
pass twenty miles to the south'ard of the far-famed lighthouse.  Here
she was in the thick of the Channel traffic, a stream of mercantile
ships passing up and down as unconcernedly as if such a thing as a
German submarine did not exist.

Although there were plenty of opportunities, Kapitan Schwalbe made no
attempt to molest the ships.  For one thing, experience had taught him
that the British merchant skipper possessed a bull-dog tenacity, and a
courage not to be daunted by the sight of a hostile periscope appearing
from nowhere in the midst of a waste of water.  For another, he was now
on the look-out for more important game--his chance to retrieve his
already vanishing prestige.

However, one of the merchant vessels served him a good purpose,
although unknown to her.  Marking a large ocean tramp bound up-Channel,
U75 dived deeply, so as to be free from any danger of being hit by her
forefoot.

With the noise of the tramp's propeller to guide her, U75 followed,
unsuspected, in her wake as she made for the Lizard Light.

Arriving safely at the rendezvous, Kapitan Schwalbe waited until it was
dark, and then cautiously brought the submarine awash.  Punctually at
ten o'clock a feeble violet light blinked through the night.  It was
U77's call to her consort.

"What's the game, I wonder?" asked Vernon, as a hail in German was
borne faintly to their ears.

The chums had turned in.  There was nothing else for them to do, since
they had been ordered to leave the quarters allotted to the crew.  As
there was no furniture of any description in the alley-way that had
been made their sleeping compartment, they had climbed into their
bunks.  Here they could maintain an almost uninterrupted conversation.

"Hist!" exclaimed Ross warningly.  He had been lying with his ear
almost touching one of the many voice-tubes that led from the
conning-tower to various parts of the submarine.  Quite by accident, he
discovered that the pipes formed an excellent conductor of sound in a
manner that had not been intended.

"What are you doing?" asked Haye curiously.

"Jam your ear against the centre one of these three pipes," said his
chum.

Vernon did so.  It required very little movement on his part, since the
bunks were rather narrow.  The same voice-tube that Ross was "tapping"
ran vertically past Haye's bunk, which was immediately underneath the
one Trefusis had appropriated from the time when he had been laid upon
it under the influence of the injection.

This particular pipe formed a means of vocal communication between the
conning-tower and Kapitan Schwalbe's cabin.  For some reason the
whistle had been removed from the cabin end, and consequently sounds
from the Kapitan's quarters were conveyed with tolerable clearness.

There were two men engaged in conversation.  One was Kapitan Schwalbe;
the other, who spoke in a lower key, and so rapidly that Ross had great
difficulty in mentally translating his words, was the
Lieutenant-Commander of U77.  He had been put aboard U75 only a few
minutes previously.

"My dear von Hoffner," Kapitan Schwalbe was saying.  "Your plan is all
very well as far as you are concerned; but where do we come in?
Understand that while we are on the surface our risks are increased
ten-fold.  Suppose, for instance, the battleship does not notice, or
affects not to notice, the white flag?"

"She will, right enough," assured the Lieutenant-Commander of U77.
"These English are such fools that in their anxiety to observe the
rules of warfare" (here von Hoffner laughed sardonically) "they play
into our hands.  More than a twelvemonth of war has not taught them
that the hitherto recognized observances of war are no longer binding.
This is not a petty squabble between two nations.  It is a struggle for
existence; consequently it is where our frightfulness scores."

"It hasn't up to the present, according to my experience," objected
Kapitan Schwalbe gloomily.  "These Englishmen simply won't be
frightened.  But to return once more to the point: what steps do you
propose to take to minimize my risk?"

"There must be risk, of course," remarked von Hoffner.  "According to
latest reports, it seems pretty certain that we cannot hope to
intercept the _Tremendous_ during the hours of darkness.  Consequently
we have to make use of a ruse.  Directly I spot her I dive, keeping as
much as possible close to her track, say three hundred metres off."

"Yes, you dive," commented Schwalbe caustically.  "That is quite
feasible.  But what of U75?"

"She will keep on the surface almost exactly in the indicated path of
the battleship.  You will strike your ensign and hoist a large white
flag in its place.  It will mean scrapping your best tablecloth, mein
herr.  With the wind in its present quarter the flag will blow athwart
the battleship's course, so there is no risk of it not being seen.  You
and your crew will, of course, form up aft.  That will give more colour
to the deception."

"Perhaps it will work," said Kapitan Schwalbe.

"Perhaps?  Of course it will," declared von Hoffher sanguinely.  "Then
the rest is child's play.  Directly the _Tremendous_ slows down--it's
the speed of these battleships that has caused us to miss hitherto--I
will let loose two torpedoes.  There will be no bungling, I assure you.
I'll take good care to hit her close to the magazine, and there will be
no opportunity for her to use her quick-firers.

"By the by, I've two English boys on board," said the Kapitan of U75.
In a few words he related the circumstances in which they were made
prisoners.  "I suppose they ought to line up on deck with the hands?"

"Certainly," replied von Hoffher, with one of his cold-blooded
sniggers.  "It will heighten the illusion.  It will do them good to see
what one of our unterseebooten can do.  But it is highly important that
there be no survivors from the torpedoed battleship.  The ruse is a
grand one, and can be employed over and over again, provided that the
secret does not leak out.  After all, I don't think I would bring these
English youths on deck."

"They are safe enough," protested Schwalbe.  "If we return to
Wilhelmshaven, they will be locked up in safe custody until the end of
the war.  If we do not, then I fancy there will be no survivors from
U75 as well as from the English battleship _Tremendous_."

The two treacherous officers conversed in a similar strain for several
minutes longer.  Then came the sound of glasses being clinked as an
accompaniment to a boastful toast.  Talking boisterously, the two
officers left the cabin, and presently the lads heard the sound of oars
as von Hoffner was rowed back to his command.




CHAPTER XI

Preparations

"The brutes!" ejaculated Vernon savagely.  He was violently excited.
Perspiration was pouring off his face at the thought of the almost
unparalleled act of wanton treachery that was about to be enacted.  "If
we could only prevent them!"

"I can't see how," rejoined Ross gloomily.  "We cannot give an alarm.
If we could control the valves for half a minute, I'd sink this blessed
craft with all on board, myself included, for good and all.  But it is
no use talking of the impossibly heroic."

"I have a plan," announced Vernon, after thinking deeply for a few
minutes.

"Well, out with it!"

"We have to pass through one of the broadside torpedo-rooms as we go on
deck.  We could each snatch a spanner and give the war-heads a terrific
blow.  You'll remember that there are half a dozen torpedoes in the
cages against the bulkhead.  It would mean certain death for us, but it
would save nearly a thousand lives."

Ross shook his head.

"There's no certainty of success," he objected.  "Those torpedoes are
very much like our own Whiteheads.  The striker in the head is
protected against accidental discharge by a small propeller.  Until the
torpedo travels a certain distance through the water--sufficient for
the resistance against the blades to cause the safety device to
unthread and leave the striker free to hit the primer--the danger of
premature explosion is almost negligible.  We shouldn't have time to
revolve the safety blades enough, and I'm pretty certain that even a
heavy blow on the war-head itself would not explode the charge."

"Then I'm done," said Vernon dejectedly.  "Think of something, old
man--something that will hold water."

Silence ensued for nearly ten minutes, broken only by the tapping of
the waves against the sides of the submarine, and the gentle purr of
the dynamos for supplying light to the interior of the vessel.

Suddenly Ross leapt out of his bunk.  He dared not trust himself to
speak above a whisper for fear of being overheard.

"Dash it all, old man!" exclaimed Vernon, when his chum had confided
his plans; "it ought to work.  If it doesn't, nothing else will.  I'm
on it, happen what may!"

"We'll want our knives for the job," continued Ross.  "Yours will open
easily, I hope?  Good!  Sharp?  We'll run no risks.  A sharp blade is
absolutely necessary."

They drew the knives and whetted the blades upon the soles of their
boots.  At Vernon's suggestion they kept open the big blades, making a
hole through the lining of their pockets in order to keep the knives in
a horizontal position and ready to hand.

"Now let's turn in properly," suggested the practical Ross.  "We want
to be fairly fresh for the job in front of us."

Soon after sunrise on the morrow all hands were mustered aft on deck,
Ross and Vernon included.  It was a bright morning.  The sun had risen
seemingly out of the sea, or in nautical parlance it was a "low dawn".
There was a chilliness in the air that made the lads wish that they had
been wearing overcoats.

They looked in vain for U75's consort.  The unterseeboot that was to
deal the coward's blow was not to be seen.  Her presence was to be kept
a secret from the crew of the decoy.

Kapitan Schwalbe, accompanied by his Unter-leutnant, made his way aft.
He looked pale and care-worn.  He had lost his military manner.  His
gait suggested that of a man recovering from a long illness.

"My men," he exclaimed, "circumstances over which I have no control
make it necessary to bring our cruise to a speedy termination.  U75 is
no longer in a state of efficiency, either for offence or flight.  It
therefore remains for us to save our lives by surrendering to the first
English ship of war that we fall in with.  It is a humiliating and
distasteful step to take, but there is no option."

The crew heard this lying speech in silence.  They hardly knew what to
make of it.  The majority mentally decided that it was better to be
imprisoned in England than to rot on the bed of the sea.  Kapitan
Schwalbe had no faith in his men's histrionic abilities; he was also
afraid that they would oppose the scheme that he himself had deprecated
as being too risky.

Hiding their indignation, Ross and his chum saw the Kapitan hand a
petty officer a white flag.  The man took it, and lashed short pieces
of cord to two adjacent corners.

Hans Koppe sidled up to his charges.

"You will soon be free," he remarked.  "Ach! but you do not seem
overjoyed.  You English are indeed a queer race."

Receiving no reply, the man went below to follow the example of his
comrades, who were getting together their personal belongings.  Many of
them thought of the times when they had seen non-belligerents do
likewise.  It was the boot on the other foot with a vengeance.

Ross gave another glance across the horizon.  Nothing was in sight.
Gripping his chum's arm, he led him for'ard.  U75 was motionless.  The
deck was deserted.  A quartermaster stood on the navigation platform in
front of the conning-tower.  Kapitan Schwalbe and his Unter-leutnant
had likewise vanished.

As Ross passed the conning-tower, he pulled out his knife and deftly
severed the lashings of a couple of buoys secured to the hand-rail.  It
was the first act of the lad's plan of operations.

"Vessel on the port bow, sir!" shouted the quartermaster.

Kapitan Schwalbe was on deck in a trice, closely followed by his
subordinate.  For a few moments, he kept his binoculars focused upon
the indistinct grey object, then three miles off.

"It is the _Tremendous_," he announced in an undertone to the
Unter-leutnant.  "Another ten minutes will see the business through."

He spoke with confidence, but it was a confidence inspired by a liberal
dose of brandy.  He felt that he had already passed the Rubicon.  There
could be no turning back.

A whistle trilled shrilly.  At the signal the men again doubled aft,
and joined up in a double line.

"Where are the English boys?" enquired Kapitan Schwalbe.

"Coming," replied Ross.  For the first time on board he omitted to add
the word "sir".  His omission was deliberate.  Utter contempt for the
German captain consumed him.  Schwalbe, too, noticed the manner in
which he had replied.  He smiled grimly, imagining that now the lads
thought themselves about to be free they could afford to be curt.

As the chums passed the lifebuoys, they deftly heaved them overboard.
They fell with hardly a splash, dropping close to the side of the
motionless submarine.

No one noticed the act.  The attention of the crew was centred upon a
little ceremony that was taking place.  Bareheaded, the men stood at
attention.  Their voices broke into the song of "Die Wacht am Rhein" as
the emblem of German sea-power was slowly lowered from the ensign staff.

The men sang sonorously and in perfect cadence.  They firmly believed
that it was their last tribute as free men to their Fatherland.  As the
last bar terminated, the petty officer smartly hoisted the white flag.
For an instant it hung limply, confined by one of the halliards; then
like a square of stretched canvas it blew out in the steady breeze--a
modern counterpart of the kiss of Judas.

And standing just behind the Kapitan, within arm's reach of the ensign
staff, were Ross Trefusis and Vernon Haye.




CHAPTER XII

The White Flag--and Afterwards

H.M.S. _Tremendous_, super-Dreadnought of 24,000 tons displacement, and
mounting ten 13.5-inch guns as her principal armament, was tearing
up-Channel at 21 knots.

She looked far different from the spick-and-span battleship which had
left Portsmouth only six weeks previously.

Her armoured sides still showed unmistakable traces of the impact of
Turkish shells.  Her grey paint was blotched, blistered, and stained.
Her after funnel had plates of sheet-iron riveted to it to hide a
gaping hole large enough to drive a stage-coach through.  Her guns were
worn out by sheer hard work.  It was mainly on this account that she
was homeward bound: to have the gigantic weapons "re-lined" in order
that she might again take her place as an effective unit of the Grand
Fleet.

The middle watch was about to relieve the morning watch.  The mess
decks were a seething mass of humanity.  In spite of the apparent
confusion everyone was in high good humour, for another few hours
(D.V.) would find H.M.S. _Tremendous_ at Pompey--as Portsmouth has from
time immemorial been termed by the Navy.

On the fire-control platform sleepy-eyed officers were awaiting their
reliefs.  Around the 12-pounders, the muzzles of which grinned
menacingly from apparently haphazard positions in the superstructure,
men were grouped, ready at the first alarm to train the weapons upon a
possible foe.  Day after day ceaseless vigilance was maintained.  One
and all realized that a moment's negligence might result in destruction
by one of the most horrible creations of modern science.

"Submarine on the starboard bow, sir!"

For an instant all was tense silence.  Then a bugle blared, followed by
the clear trills of the bos'n's mates' pipes and the hurried tramp of
men's feet.

The officer of the watch brought his telescope to bear ahead.  He was a
junior lieutenant, Bourne by name, and in receipt of a private income
of eight hundred a year.  On that sum he might have lived the life of a
man of leisure, but he vastly preferred a strenuous life as a
commissioned officer in the Royal Navy.  Not once had he regretted his
choice, and upon the outbreak of war he was ready to execute a hornpipe
of sheer delight at the prospect of "being in the big scrap".

"She's flying the white flag, by Jove!" he ejaculated.  "Funny,
deucedly funny!"

He had to act, and act promptly, for a battleship travelling at 21
knots does not give a man time to think for any length of time.
Already a messenger had been despatched to inform the "skipper", but
before the captain could gain the navigation bridge (more than likely
he was in his bath) the _Tremendous_ would have covered the intervening
distance.

The quartermaster looked enquiringly at the Lieutenant.  Bourne stepped
hastily to the engine-room telegraph indicator, half inclined to ring
down for "half-speed", or even "stop both engines".

He stopped abruptly.

"Steady on your helm, quartermaster."

"Steady it is, sir," replied the petty officer.

The telegraph indicator remained untouched.  With undiminished speed
H.M.S.  _Tremendous_ held on, under the propelling force of turbine
engines of 30,000 indicated horse-power.

A midshipman, standing by the side of the officer of the watch, had
been keeping the submarine under observation by means of his telescope.

"By Jove, sir!" he exclaimed.  "There's something wrong there.  The
white flag's down, and two fellows in mufti have leapt overboard."

"Torpedo on the port bow, sir!" sang out half a dozen lusty voices in
chorus.

"Hard-a-port, quartermaster!" ordered Bourne.

The spokes of the steam steering-gear revolved quicker than they had
ever done before.  Listing heavily to port, the _Tremendous_ turned
with a rapidity that belied her huge bulk and apparent unhandiness.  A
double track of ever-diverging foam marked the progress of the deadly
missile.  Another followed almost in its wake, both torpedoes
travelling at the speed of an express train.

For four seconds all on board who watched these messages of death stood
with bated breath.  Then a general roar of relief went up as the two
"tinfish" glided harmlessly past the ship, the nearest at a distance of
less than twenty feet, and parallel to the new course of the battleship.

Half a dozen quick-firers spat viciously.  A 6-inch, two of which for
some obscure reason the designers had placed on the main deck abreast
of the after 15-inch guns, added to the din.  A chaos of smoke, flame,
and spray marked the spot beneath which U77 had lurked to launch her
cowardly and treacherous bolt.

"That's blinded her, at least," thought Bourne.

He knew that even if the hidden submarine had escaped injury, a minute
at least would elapse before she could be conned into a position to
discharge another torpedo.  That minute would be enough for his purpose.

"Starboard!" he ordered.  "Ram her, quartermaster!"

Round swung the 24,000 tons of dead weight, steadied, and bore down
upon the motionless U75.  Cries of terror burst from the doomed crew,
many of whom leapt overboard in a vain attempt to swim clear of the
vengeful leviathan.

Bourne gripped the guard-rail, half expecting to be thrown violently by
the force of the impact.  He was mistaken.

With hardly a tremor the bows of the _Tremendous_ crashed into the
unterseeboot, hitting her just abaft the conning-tower.  The bow
portion sank like a stone.  The after part reared itself high in the
air, revealing the curiously shaped stern, the two propellers, and the
complication of rudders.  Then, before the cloud of smoke and spray had
time to drift inboard, the _Tremendous_ was over and beyond the
ever-widening circle of iridescent oil that marked the ocean grave of
yet another of the would-be blockaders of Britain's shores.

Even in the midst of his great responsibility Bourne's keen eye
discerned two heads bobbing up and down in the water.  The midshipman
noticed them too.

"They are those fellows who hauled down the white flag, sir," he
exclaimed.  "They are quite youngsters, too, and we daren't stop."

"No, we dare not," agreed the Lieutenant.  For aught he knew, another
unterseeboot might be in the vicinity, reserving her torpedoes in the
hope that the battleship would slow down to investigate.  "Pass the
word to the sentry to let go the Kisbie.  It's the best we can do."

With a splash the patent lifebuoy was dropped from the cage at the
extremity of the navigation-bridge.  It bobbed up again under the
battleship's quarter, emitting a dense cloud of calcium smoke as it did
so.  By the time the marine had dropped the Kisbie the ship was a
quarter of a mile away from the two swimmers.

"It's the best we can do," repeated Bourne as he closed the eyepiece of
his telescope.  "They may fetch it, they are swimming strongly."

"Well done, Mr. Bourne!" exclaimed a deep voice.

Turning, the Lieutenant faced the Captain standing beside him.

"A smart manoeuvre!" continued the skipper approvingly.  "We can now
only carry on; but we'll wireless the Commander-in-Chief Devonport, and
report that there are survivors from the rammed submarine.  He'll have
a destroyer patrol on the spot within an hour, and I hope it won't be
too late."

Bourne stepped to the extremity of the bridge and glanced astern.  His
effort to distinguish the heads of the two swimmers was fruitless, for
a thin haze, the smoke from the ship's funnel, spread far in her wake,
completely obliterating the spot where Ross Trefusis and Vernon Haye
were swimming for dear life.


It will be necessary to set back the hands of the clock in order to
follow the fortunes of Ross and his chum.

"Is she slowing down?" whispered Vernon anxiously, as they stood on the
deck of U75 awaiting the approach of the _Tremendous_.

"I don't think so," replied Ross.  "But now's our time."

The attention of Schwalbe and his crew was centred upon the battleship;
the Kapitan momentarily expecting to see the huge vessel reel under the
impact of the terrible torpedo, while the men began to entertain grave
doubts as to whether the British ship would accept their token of
surrender.  The fact that the super-Dreadnought showed no signs of
slowing down revived Kapitan Schwalbe's doubts.  Knowing the difficulty
of hitting, even at a comparatively short range, a swiftly moving
target, he began to wonder whether he did the right thing in falling in
with von Hoffner's diabolical plan.

His hurried thoughts were suddenly interrupted by some light object
enveloping his head and shoulders.  Before he could tear the fabric
away he heard two distinct splashes, followed by shouts of astonishment
from the crew; for with one clean sweep with his knife Ross had severed
the halliards of the ensign staff.

The lads dived deep, swimming the while with long, powerful strokes,
for both were accomplished in the art of natation.  They were longer in
coming to the surface than they anticipated, owing to the weight of
their half-boots, which they had been unable to remove without risk of
causing suspicion.

When at length their heads emerged almost simultaneously, they found
themselves nearly fifteen yards from the doomed U75.

"Strike out!" spluttered Ross.  "Get as far away from her as you can.
Never mind about old Schwalbe.  He can't hurt us."

Ross was right, for however much the Kapitan wanted to wreak his
vengeance upon his former prisoners, he was unable to do so.  In his
role as that of an officer waiting to surrender, the possession of a
revolver would tend to "give the show away".  He had left his pistol in
his cabin--an example that his Unter-leutnant had followed.  And now
his attention was directed upon the British battleship.

Meanwhile, the lads, swimming strongly, saw the _Tremendous_ heel as
she ported helm.  For a minute, not knowing how a ship behaves when the
helm is suddenly put hard over, they thought that the treacherous
unterseeboot had successfully carried out her cold-blooded plan.  Yet
no explosion occurred, and the battleship recovered her normal trim.

With their eyes only a few inches above the surface, the lads could see
nothing of the track of the torpedoes.  They had no indication that
they had been fired until the _Tremendous_ let fly with her 12-pounders.

"I think we've saved her," said Vernon.  "Now there'll be trouble for
us.  Schwalbe will certainly have a shot at recapturing us after the
battleship has cleared off.  Why doesn't she settle U75, I wonder?"

The lads both expressed astonishment that the motionless unterseeboot
had escaped the attention of the super-Dreadnought's quick-firers.  It
seemed as if the latter were ignoring U75 altogether and was sheering
off at full speed.

Suddenly Ross gave a whoop of delight, which ended in his swallowing a
mouthful of salt water.  The _Tremendous_ was turning once more, and
heading straight for the doomed submarine.

[Illustration: "THE _TREMENDOUS_ WAS HEADING STRAIGHT FOR THE DOOMED
SUBMARINE"]

Mentally Ross compared the on-coming battleship with an express train,
as shown on a cinematograph screen, in the act of approaching the
audience.  At one moment the ship was visible from her water-line to
the truck of her top-mast; at the next her bulk had suddenly expanded
and seemed to fill the complete field of vision.  It looked as if the
two lads, in spite of the distance they had put between themselves and
the motionless submarine, would yet be in the way of the vengeful
battleship, whose extreme beam was not less than ninety feet.

Yet neither of the two chums made the slightest effort to swim farther
away.  Mechanically treading water, they waited and watched.

They could see the terror-stricken attitudes of the crew of the doomed
U75.  They heard the shouts of consternation as the massive steel bows
bore down upon her.  Then, in a second it seemed, there was a hideous
crash that outvoiced the yells and shouts of despair as the
unterseeboot was rent in twain.

Of what happened during the next minute the lads had but a very hazy
idea.  Caught by the irresistible bow wave as the _Tremendous_ tore
past, they were hurled aside like feathers and buried a couple of
fathoms down under the breaking, foaming mass of water.  Vaguely they
heard the whirring of the four propellers--very near, it seemed; then,
caught by an eddy caused by the cavitation in the wake of the monstrous
vessel, they were separated and flung to the surface, half-breathless
and dazed.

Ross opened his eyes.  The _Tremendous_ had already covered nearly a
quarter of a mile.  Twenty yards away he saw his chum's head, as
Vernon, puffing like a grampus, was striking out towards him.

Where the submarine had dived for the last time was an ever-widening
circle of oil.  Those of the German crew who had not been carried down
by the sinking unterseeboot were too shaken by the concussion to make
any great effort to save their lives.  Attempting to keep afloat in
that oil-covered water added to their difficulties, for whenever the
head of a swimmer disappeared he did not rise again.

"Kick off your boots, old man," exclaimed Ross.

"Where are the lifebuoys?" asked Vernon as he carried out his friend's
advice.

One buoy had disappeared; the other was supporting a seaman, the only
survivor of the crew.

"A case of finding's are keeping's," announced Ross.  "We can't sling
him out of it.  It might support two people.  We could take turns at
hanging on."

"Stop!" exclaimed Vernon as Ross began to strike out towards the buoy.
"There'll be trouble if we get mixed up in that oil.  It's much lighter
than water.  I doubt whether we could swim in it.  Do you think the
_Tremendous_ will put back?"

"Not likely," replied Trefusis.

He looked in the direction of the fast-vanishing battleship, half
hoping that she would slow down and lower a boat.  As he did so,
something caught his eye: a cloud of grey smoke apparently issuing from
the sea.

"What's that?" he asked, pointing in that direction.

"Torpedo, perhaps; one that has finished her run," suggested Vernon;
but his chum waved aside the explanation.

"If U77 did fire a torpedo, you can bet your bottom dollar it wasn't
one with a dummy head!" he said.  "Only practice torpedoes send up a
calcium light when their compressed air has given out.  By Jove, I
believe it's one of those patent buoys!  Let's make for it."

The lads swam strongly, making powerful and comparatively slow
breast-strokes.  The water was warm.  They were in no immediate danger
of cramp.

As they skirted the patch of oil they noticed that the seaman holding
on to the buoy had turned round.  His face was now in their direction.
The man was Hans Koppe.

"Are you all right, Hans?" shouted Ross.

"Yes, mein herr," replied the man.  "I've found a buoy."

"Thanks to us," thought Trefusis; then raising his voice: "You had
better kick out and get clear of the oil," he advised.  "We are making
for yonder buoy."

By the time the swimmers reached the Kisbie the emission of calcium
smoke had ceased.  They found that not only did the buoy support them
both, but that it was so constructed as to allow them to maintain a
sitting position without having to hold on with both hands.  Glad of a
seat they waited, watching the approach of Hans Koppe, and also looking
for the undesired reappearance of U77.

"Ach!  My wife and children!" exclaimed Hans Koppe disconsolately, as
he brought his lifebuoy close alongside.  "I shall never see them
again."

"Cheer up, Hans!" replied Vernon.  "At any moment U77 might come to the
surface and take you on board.  We don't mind, so long as they let us
alone.  We've had enough of your unterseebooten."

"U77?" gasped the German incredulously.  "How do you know that?"

Briefly Haye related the story of the ill-fated Kapitan Schwalbe's
treachery.  As he proceeded Han's face bore a surprised expression that
presently changed to one of fear.

"If we are picked up by an English ship," he remarked, "they will shoot
me for abuse of the white flag.  And I am innocent.  Ach! my poor wife."

"They won't," replied Ross reassuringly.  "We can swear that you knew
nothing about it."

The minutes passed slowly.  There was no sign of U77.  Little did the
three survivors know that she lay within a quarter of a mile of her
consort, on the bed of the English Channel--to add to the
ever-increasing roll of unterseebooten that were fated never to enter a
German port again.

The sun rose higher and higher, its rays gathering strength as it did
so.  The heads of the three survivors were exposed to the solar heat;
their bodies and limbs were numbed by prolonged immersion.  The desire
for conversation had long since passed.  Almost exhausted they hung to
their supports, listless and torpid.  A few sea-gulls, struck with the
silence of the three men, hovered overhead, and swooped with shrill
cries to settle on the water within close distance of what appeared to
be a possible meal.  One bolder than the rest perched upon Trefusis'
head.

Raising his arm, Ross dealt the bird a furious blow.  It missed, but
had the effect of scattering the gulls.  Apathetically the lad watched
them as they flew off.  As he did so he caught sight of three vessels
being driven at high speed.

"Hurrah!" he exclaimed feebly.  "The destroyers, old man; we are saved!"




CHAPTER XIII

The Arm of the Law

"Hulloa!  What the deuce have we got here?" enquired Commander Devereux
of H.M. torpedo-boat destroyer _Yealm_, as three dripping figures were
transferred from the destroyer's dinghy to the deck.  "One strafed Hun,
right enough; but who are these fellows in mufti?"

"Can't say, sir," replied the coxswain.  "They sort o' collapsed
directly we got 'em into the boat."

"Then take them below," continued Devereux.  "I say, Fanshawe, there's
a job for you at last, my festive sawbones."

Fanshawe, lately a young country practitioner with a scattered "panel"
connection, had but recently entered the Navy as a surgical probationer
R.N.V.R.  He joined purely through patriotic motives, having sacrificed
a fairly substantial income in order to do so.  Up to the present his
work had been almost a sinecure.  The _Yealm_ had not had the faintest
chance of taking part in an engagement.  Her crew--to use Fanshawe's
own words--were "that beastly healthy, don't you know", that, out of
sheer anxiety to do something, he was learning navigation from the
Sub-lieutenant.

The medico undertook his first important professional task on board the
_Yealm_ with great alacrity, and it was not long before Ross and Vernon
were in a fit state to be questioned.  Hans Koppe was in a bad plight.
So utterly shaken were his nerves that he seemed on the point of
collapse.

"So you are the son of Admiral Trefusis," said the
Lieutenant-Commander.  "I can't say that I know him personally,
although I know of him.  But how did you get on board the submarine?"

Ross explained.  He felt hurt at having to do so.  The
Lieutenant-Commander's ignorance of the disappearance of the two chums
from St. Mena's Island "took all the wind out of his sails".  In
pre-War days the principal papers would have devoted at least half a
column to the supposed deaths by drowning, off the Cornish coast, of
two well-connected youths.  Nowadays editors had neither space nor
inclination to devote to such a comparatively trivial matter.
Consequently Devereux could be exonerated of all lack of knowledge of
the supposed accident.  Yet his interest grew as Ross proceeded with
his narrative.

"Look here," he remarked.  "We've got to dodge around for a few hours
in case your pal U77 does put in an appearance.  But I'll wireless the
Admiral and ask for a telegram to be sent to your homes, to let your
people know you are still alive and kicking."

"Better not, sir," objected Ross.

Devereux looked curiously at the lad.

"And why not?" he asked.

"Well, you see," explained Trefusis, "a telegram is not such a
confidential matter as one would like it to be, especially in a remote
country district."

"It's good news though," remarked the Lieutenant-Commander.

"Yes," admitted Ross; "but it is absolutely necessary to keep it dark
for a while.  A few hours won't make very much difference one way or
the other to my people, but it would make a thumping lot to our friend
Dr. Ramblethorne, otherwise von Hauptwald.  If he were to hear that we
were alive, he'd do a bunk.  The same with that other spy, von Ruhle.
They must be arrested promptly, and within a few hours of each other,
in case one of them scents trouble and clears out."

"I see your point," admitted Devereux.  "I won't send a wireless at
present.  You must be feeling peckish.  I'll get my steward to bring
you in some grub.  Excuse me, I must be off again.  We've a lot to
attend to, you know."

The Lieutenant-Commander went on deck to conduct operations.  He was
temporarily senior officer, and it fell to him to issue orders to his
two consorts relating to the investigation of the scene of the
battleship's exploit.

For two hours the three destroyers cruised over the spot where the two
submarines were supposed to have sunk.  At length wreckage was found by
means of grapnels.  It was, of course, much too deep to send a diver
down to report; but the spot was buoyed, and served as a base while
sweeping operations were proceeded with in the hope of locating the
hull of the second unterseeboot.  In a very short space of time two
operations undertaken for the purpose of destroying the sunken
submarine were highly satisfactorily carried out.  The first resulted
in the release of a small quantity of buoyant wreckage, amongst which
was the flagstaff of U75.  The second brought to the surface a quantity
of oil, showing that a submarine had been sunk there, but the injuries
she previously received had not been sufficient to liberate the
contents of the heavy oil-tanks.  The explosive charge had completed
the destruction of U77.

Just before five in the afternoon, the _Yealm_ and her consorts passed
the eastern arm of the breakwater in Plymouth Sound and brought up in
the Hamoaze.  Ross and Vernon, arrayed in borrowed clothes and
accompanied by Lieutenant-Commander Devereux, lost no time in going
ashore and proceeding to the offices of the Commander-in-Chief.

"You are acting with remarkable discretion," observed the Admiral, when
Ross reiterated his desire not to communicate with his home until the
spies were safely under lock and key.  "Fortunately there ought to be
no undue delay, as we have two expert Scotland Yard men investigating a
case in the Dockyard.  I'll telephone to the Superintendent of Police,
and get him to send the officers here at once."

Within ten minutes the officers were ushered into the
Commander-in-Chief's presence.  Ross and Vernon looked at them with
considerable curiosity.  It had not before fallen to their lot to come
into contact with two real representatives of the famous Scotland Yard.
Yet there was little about the appearance to occasion comment.  They
were not in any way disguised.  The taller of the two, who was
introduced as Detective-Inspector Ferret, was about forty years of age.
His closely cut hair was dark-brown, with a plentiful sprinkling of
grey hairs.  He wore a beard trimmed naval or "torpedo" fashion, with a
moustache.  He was dressed in a grey lounge suit, with dark-brown boots
and a golfing cap.  There was nothing of a piercing nature about his
eyes, which were of a deep-grey tint.  He seemed to be perpetually
beaming; the lines on his face gave one that impression.

His companion, Detective Hawke, was a short, thick-set man of about
thirty-five.  He was clean-shaven.  His features were ruddy and heavy.
There was a bulldog look about his jaw that proclaimed him to be a
tough customer.  His rough, brown, Harris-tweed suit and bowler hat
gave him the appearance of a prosperous yeoman rather than a successful
tracker of criminals.

"Now, young gentlemen," began Mr. Hawke briskly, after the
introductions had been made, "we'll get to business.  With your
permission, sir" (addressing the Admiral), "I will ask Mr. Trefusis to
give me his version of the affair.  To save time, I feel certain that
Mr. Haye will have no objection to going with my colleague and telling
him his story.  That, I must explain, is the best way to eliminate any
discrepancies.  We prefer to make a fair start, and then all ought to
go well."

During the next hour Detective-inspector Hawke was very busy.  He made
no written notes.  He relied solely upon his marvellous retentive
memory, and it was not long before he was in full possession of the
facts of the case.

His next step was to telephone to St. Bedal.  From the police there, he
learnt that Dr. Ramblethorne was medical officer to the 4th battalion
of a west-country regiment, but that he was temporarily detailed to act
on the recruiting staff at Wellington.

Hawke thereupon telegraphed to Harwich.  The Customs officers there
informed him that the Harwich-Flushing boat service had been suspended
for nearly a week, owing to the discovery of a hostile mine-field off
the Dutch coast.  Sailings were to be resumed that night.  A man who
gave himself out to be a Dutchman, but who answered to the description
of von Ruhle, had applied that morning for a permit to leave the
country by the night boat.  His berth had been booked under the name of
Cornelius Vanderhuit.

"Which one ought we to nab first?" asked Ferret.  "We'll have to be
very sharp, or one of them, finding that he is no longer in
communication with his accomplice, would smell a rat and clear out."

"Under normal conditions I would reply, 'Collar the principal first',"
replied Hawke.  "It is evident that Ramblethorne, _alias_ von
Hauptwald, is the master-spy.  Directly he's laid by the heels, the
whole of the organization immediately under his control goes by the
board.  But there's this Harwich business.  Von Ruhle crosses the North
Sea to-night, unless otherwise prevented.  We comprise the otherwise, I
hope."

"Then it would mean catching the midday express to Waterloo," remarked
Ferret.

"Could we go with you?" asked Ross.

The police officers looked rather astonished at the cool request.  Like
most professional men, they scouted the idea of amateur assistance when
the main issue was at stake.

"Perhaps it wouldn't be a bad idea," remarked Hawke.  "You have already
shown great discretion in the matter.  Most fellows would have made a
bee-line to the nearest telegraph office and given the whole show away.
The only difficulty is--I suppose, by the way, you are not feeling too
done up after your trying experiences?--the only difficulty is, I was
remarking, that von Ruhle might spot you.  Look here, Ferret; suppose
you take these young gentlemen, and proceed to Harwich by an ordinary
train?  Keep well out of sight when you arrive at Parkeston Quay, but
keep a sharp eye on the boat.  I'll travel from Liverpool Street by the
boat train, and see if I can pick out our quarry amongst the
passengers."

It was a tedious journey from Plymouth to Harwich.  Arriving at
Waterloo, Ferret took the lads to a quiet hotel and ordered lunch;
while Hawke, excusing himself, called in at "the Yard" to report his
new case to the Chief, and to wait for the Great Eastern boat train.

The weather had changed completely during the run from the West, for
when Ferret and the two lads arrived at Parkeston Quay it was raining
heavily, accompanied by half a gale of wind from the east'ard.

"We've a long wait," commented Ferret.  "Fortunately I know several of
the Customs officials very well.  I'll get them to let you take shelter
in their shed.  It's almost opposite the berth where the steamer
generally makes fast.  You'll be able to watch everyone who goes up the
gangway.  I'll go on board and speak to the steward.  I don't suppose
we'll spot friend von Ruhle until the boat train arrives, and by that
time perhaps Hawke will have marked his man."

Undoubtedly, the wisest course would have been to send other officers
to Wellington to arrest Dr. Ramblethorne; but Hawke was out for
"kudos".  Only a short while ago he had let a wanted man slip through
his fingers, and had been rapped over the knuckles for it.  With the
professional assistance of Ferret, he hoped to carry out a double
_coup_ and arrest both German Secret Service agents, thereby recovering
his lost prestige.

Arriving at Liverpool Street he took his ticket, and spent the time
until the departure of the boat train in walking up and down the
platform.  He had the knack of observing without being observed.  He
would look at a man in quite a casual way; there was no gleam of
intelligence in his eyes as he did so, but little escaped his notice.
An hour or two later he could accurately describe his appearance,
dress, and mannerisms.

A minute before the train started, a man answering von Ruhle's
description hurried down the platform.  He carried a new cane under his
left arm.  In his right hand he held an attache case with the initials
C. V.

Hawke waited until he had entered a carriage, then strolled to the
other end of the corridor coaches and took his seat.  He knew that the
run was supposed to be a non-stop one.

The train started.  The detective took his time.  He waited for nearly
twenty minutes before he made his way along the corridor, and entered
the smoking-compartment occupied by the suspect.

Presently Hawke made a commonplace remark.  The stranger replied
stiffly and in rather a deep voice, with a slight foreign accent.

"An assumed voice," soliloquized the detective; but undaunted by the
chilliness of his reception he again made some remark about the weather.

Before the train ran through Witham station, conversation was
proceeding briskly.  Hawke assumed the role of a commercial traveller,
and volunteered the information that his brother had just returned from
the Front.

The stranger showed no hesitation in discussing the war.  Emboldened,
the detective tackled the subject of East Coast defences and the futile
German blockade.

"He's giving me absolutely false information," he thought.  "Perhaps
he's trying to throw me off the scent.  I'll put a few questions that
no one but an ignoramus would ask in good faith.  If he's trying to
bluff me, I'll beat him at that game."

Presently his fellow-passenger excused himself and, without removing
his luggage, went into the corridor.  As soon as he was out of sight
Hawke took hold of the cane that the stranger had left in the rack.
With a grunt of satisfaction he found that it was certainly not a
Malacca, but made of metal.

The train began to slow down.  Lifting the blind, Hawke looked out of
the window.  He could just discern a fairly big town, completely in
darkness.

"Manningtree Junction," said Hawke to himself.  "Something on the line,
I suppose.  H'm, we're stopping."

With a jerk the train pulled up at the station.  The platform was
almost deserted, for no train was due at that time to stop there.  A
door slammed.  Again the detective pulled aside the blind.  He was just
in time to see his fellow-traveller, accompanied by the guard,
disappear into the station waiting-room.

"He's tumbled to it!" exclaimed Hawke.  "He's making off.  He's tipped
the guard to set him down.  I'm after him!"

He made his way swiftly and stealthily down the platform, and with a
quick movement threw open the waiting-room door.

The sudden transition from the semi-darkness of the platform to the
brilliantly lighted interior of the room temporarily dazzled his eyes.
Dimly he was aware that the place was occupied by khaki-clad soldiers
struggling into their equipment, and that in their midst was the guard
and the man of whom he was in search.

"At any rate there is plenty of assistance," thought Hawke as he
advanced to tap the suspect on the shoulder; but before he could attain
his object a deep, stern voice exclaimed:

"Arrest him, men!"

The next instant Detective-inspector Hawke was seized by half a dozen
muscular hands.

"What's this tomfoolery?" he demanded angrily.  "I'm a Scotland Yard
officer, and----"

A roar of laughter burst from the Tommies.  Even the subaltern in
command smiled broadly.

The stranger spoke again.

"Take him to the guard-room.  He is arrested under the Defence of the
Realm Act for attempting to elicit information prejudicial to the
welfare of the State.  I won't detain the train any longer, guard,
although I'll ask you to drop my gear on the platform."

Still protesting vehemently but ineffectually, the detective was
unceremoniously hustled into an ante-room, used since the outbreak of
the war as a guard-room for the military in charge of the line.  The
door was locked upon him.  He heard the train rumble out of the station.




CHAPTER XIV

A Fruitless Quest

From their places of concealment Ross and Vernon watched the boat train
run alongside the steamer.  At last the weary vigil was a thing of the
past.  All fatigue was forgotten at the prospect of witnessing the
capture of one of the active members of the German spy system at work
in this country.

For a quarter of an hour everything was in a state of bustle.  There
was a continuous stream of passengers and porters, the latter bending
under the weight of trunks and boxes as they hurried up the steeply
sloping gangway.

At length the throng thinned.  As yet there was no sign either of von
Ruhle or of Detective-inspector Hawke.

A man with his coat collar turned up ran through the driving rain and
entered the shed.  It was Ferret.

"Something's gone wrong," he declared.  "I've just had a telephone
message from my colleague.  I'm off to the post-office.  If you want me
during the next ten minutes you'll find me there."

Hawke had at length managed to get a word with his former
fellow-traveller, who happened to be a staff-officer of the Eastern
command.  The detective had been under a misapprehension.  The officer
had good reason for ordering his arrest; but the comedy threatened to
take a serious development.  Even when the detective showed his
credentials the officer was not satisfied.  He proposed telegraphing to
Scotland Yard, but Hawke, mindful of a former failure, induced him not
to do so.  The detective, who had occasion to contrast unfavourably the
summary powers of arrest under the Defence of the Realm Act with those
allowed by the Civil Power, was eventually allowed to communicate with
his brother officer at Parkeston Quay.  And then the military
authorities required a considerable amount of convincing.  It looked as
if Detective-inspector Hawke would have to remain under arrest until
next morning.

While Ferret was losing time and patience in his efforts to release his
confrere, Ross and Vernon noticed a man hurrying along the quay.  He
was short and thick-set.  He wore a long mackintosh, the collar of
which was turned up and helped, with the peak of his cap, to hide his
features.

Suddenly the man's foot tripped over a ring-bolt.  He cursed under his
breath, but sufficiently loudly for the lads to overhear.

Ross gripped his companion's arm.  The fellow was swearing in German.

"Von Ruhle!" he whispered.  He made a movement as if to issue from his
place of concealment, but Haye restrained him.

"Hold on!" he cautioned in a low voice.

The man paused on the gangway.  A partly shaded electric light threw a
glare upon his face.  He wore a heavy beard and moustache.

"You're wrong," whispered Vernon.

"He's a German, anyhow," persisted Trefusis.

The man still hesitated.  Then he hailed a seaman.

"Where is the post office?" he asked.  "I wish to telegraph.  Is there
time before the boat sails?"

Receiving an affirmative reply the man hurried off.

"Come on!" exclaimed Ross.

Neither of the lads had now any doubts as to the man's identity.  The
beard and moustache were false, but the voice was the same--von Ruhle's.

Keeping close to the wall of the line of sheds, the lads followed the
spy at a distance of about fifty feet.  More than once von Ruhle
glanced furtively over his shoulder, as if suspecting that he was being
tracked.

Presently a man, reeling along the quay, approached.  The spy made no
effort to avoid him.  As the inebriated one rolled past he whispered a
few words.  The effect was instantaneous.  Instead of continuing his
way towards the post office, von Ruhle turned and made off abruptly in
the direction of the gate of the Company's premises.

"An accomplice," whispered Vernon.  "He's been warned."

They had to wait until the man who had feigned drunkenness had
disappeared.  By this time the German had gained a considerable
distance.  To get the assistance of the detective was out of the
question.

"Come on!" exclaimed Ross, breaking into a run.

Concealment was no longer necessary.  Should occasion arise, there
would be plenty of help forthcoming, for there were several dock
policemen and soldiers on duty close at hand.

Von Ruhle had increased his pace into a brisk walk when he heard the
noise of his pursuers.  Then he, too, began to run.

"Stop him!" shouted Trefusis, calling to a group of uniformed men
standing in front of an abattoir.

Turning, the German made towards the quay-side.  He was no match in
speed for his youthful pursuers; but he gained the water's edge before
Ross headed him off.

"Give in, von Ruhle!" he challenged.

The spy recognized the voice of the British lad whom he imagined to be
miles away, on board an unterseeboot.

With a quick movement, the spy plucked a leather case from his coat
pocket and hurled it over the edge of the quay, then, throwing up his
arms, he dropped lifeless upon the rain-sodden ground.

Rapidly a crowd collected.  Amongst them was Detective-inspector
Ferret, who, having finished his conversation with his luckless
confrere, was leaving the post office when he heard the commotion.

"Well, what's all this?" he asked brusquely.  He bent over the body of
the spy and flashed a pocket-lamp upon his face.  "It's our man," he
continued, addressing the lads in an undertone.  This remark was
needless, since they were already certain upon that point.  "He's done
us out of a job.  Heart disease?  No fear: it's poison.  Don't wait
here.  Your work in this direction is done.  I have still a few
unpleasant tasks to perform.  Cut off to the hotel and await me there.
I may be an hour."

"One moment," protested Vernon.  "We saw von Ruhle heave something over
the quay.  It might float; if so, there might be a chance to pick it up
by means of a boat.  The tide is almost slack.  If it has sunk it will
be a diver's task to recover it."

"'Something' is always unsatisfactory," remarked Ferret reprovingly.
"Was it large, small, heavy, or light?"

"He was so jolly quick that I could hardly see it," replied Haye.  "I
should think it was about the size of a cigar-case."

Directing two policemen to remove and take charge of the body, the
Detective-inspector accompanied the lads to the edge of the quay.  It
was dead low water.  There was hardly sufficient current coming down
the Stour to swing the anchored craft against the wind.  Then the
investigators made a discovery.  Although there was a good depth of
water at the greater extent of the quay, at this spot the mud was
uncovered at the base of the wall, while almost at their feet was a
flight of stone steps.

Ferret descended cautiously and switched on the light of the torch.
Almost within arm's length, and partly buried in the slime, was the
object which the spy had thrown away.

As the detective hooked at it with his stick a hoarse voice shouted:

"Ahoy there!  What are you doing with that light?"

Apparently from nowhere a boat ploughed through the mud until its bows
were within a couple of feet of the steps.  The next instant Ferret and
his companions were covered by a revolver.

It was a naval guard-boat, the watchful eye of the officer in charge
having discovered what he took to be surreptitious signalling.
Explanations followed, and were accepted.  Ferret, holding the
recovered prize, ascended the steps, followed by Ross and Vernon, while
the boat backed noiselessly away.  It was but one more example of the
ceaseless vigilance of the great, silent Navy.

Almost dead-beat, Trefusis and his chum made their way to the hotel,
had supper, and went straight to bed.  Ferret, they decided, could wait
until morning.

At 6 a.m. Hawke, having secured his release, arrived at Parkeston,
having engaged a motor-car to bring him from Manningtree.  Already his
vindictiveness towards the military had vanished.  He had taken a
sensible view of the situation.  He had played and lost, and the staff
officer was justified in the circumstances.  As for the soldiers, they
had to obey orders.

Nevertheless he was chagrined when he heard his confrere's report.  It
was galling to think that their spy had outwitted him by taking his own
life.  The whole energies of the two detectives must, for the present,
be concentrated upon the capture of the master-spy, Von Hauptwald,
otherwise Dr. Ramblethorne.

Ross and Vernon met Hawke again at breakfast.  He was now quite
cheerful.

"You managed to get hold of von Ruhle so well," he remarked, "that I
think you really ought to bear a hand with friend Ramblethorne,--that
is, unless you've had enough of man-hunting?"

"We'll do our best," said Ross.  "It's our duty."

"When do you start?" asked Vernon.

"Almost at once," he declared.  "Ramblethorne might be alarmed if no
telegram arrives from his fellow-spy.  Again, the man who communicated
with von Ruhle on the quay last night might have given Ramblethorne
warning.  It's not at all surprising to me, since what you told us, Mr.
Trefusis, that there has been an alarming outbreak of enteric at St.
Bedal camp."

He turned over several pages of a complex timetable.

"Here we are," he announced.  "We must get to Paddington in time to
catch the 10.20 for Wellington.  One thing, young gentlemen, you'll be
nearly home.  Ferret has arranged about the inquest on von Ruhle.  Your
evidence will be taken down in writing, and in that case you won't have
to put in an appearance at that grim farce."

Hawke spoke feelingly and from experience.  In his opinion, based upon
circumstantial evidence, "crowner's quests" were a form of legal
absurdity.

The train journey to Liverpool Street was undertaken almost in silence,
as far as the four travellers were concerned.  Hawke buried himself in
his paper; Ferret was poring over some document found in von Ruhle's
pocket-book, trying to unravel the complex code that, if deciphered,
would be of the utmost importance to the country.  Ross and Vernon,
still feeling tired, tried to make up for arrears of sleep.

Taking a taxi across London, they were just in time to catch the Great
Western express, which would take them to Taunton.  Arriving at that
place, they changed into a slow train that eventually landed them at
the little Somersetshire town nestling under the Black Down Hills.

Without delay the party proceeded to the regimental depot.  Enquiries
for Captain Ramblethorne, R.A.M.C., only resulted in looks of
perplexity.  He was unknown to the authorities.

"But we heard from St. Bedal that Captain Ramblethorne was ordered to
Wellington for recruiting duties," persisted Hawke.

The orderly-room clerk smiled sadly.

"Are you quite sure that it was this Wellington?" he asked.  "We've had
similar mistakes before."

Detective-inspector Hawke felt like kicking himself.  He, too, was
aware of the existence of the Shropshire Wellington, but, without
giving the possibility any consideration, he had rashly jumped to the
conclusion that the place to which Ramblethorne had been appointed was
the one nearest to St. Bedal.

Sorrowfully the four marched out of the office.  More delay ensued
while a wire was dispatched to St. Bedal, asking for further details.

It took two hours before the reply came.  "Regret not to have added
Salop to Captain Ramblethorne's address.--C.O."

"It's a long lane that has no turning," observed Ferret as they made
for the railway station.

Hawke bit his lip.  He knew that had the spy been warned promptly he
might be out of the country by this time.

It was dark when, after a tedious journey, the four travellers alighted
at Wellington, Salop.  Here, guarded enquiries elicited the information
that Captain Ramblethorne had gone to Bridgnorth to examine men "roped
in" at a recruiting meeting.  He had left for Bridgnorth two hours
previously.

"There are no trains to-night," announced Hawke.  "We'll have to get a
car."

Ten minutes later, Ross and his companions were speeding over the
horribly rough and hilly road between Wellington and Bridgnorth.  Past
ironworks and coal-fields, over or under a network of railway lines,
the car tore; then, leaving the mining district behind, it entered the
picturesque valley of the Severn, where the road skirts a range of
towering limestone crags.

In spite of their fatigue, the lads could not restrain an exclamation
of surprise and delight as the town of Bridgnorth, bathed in moonlight,
appeared in sight--a cluster of houses perched upon a bold rock, and
dominated by the scanty ruins of the old castle.  At the foot of the
cliff the Severn meandered placidly.  In the midst of the greatest war
the world has ever known, Bridgnorth appeared to retain all the
characteristics of complete peace.

The recruiting office was closed for the night.  With unerring instinct
the detective made for the principal hotel.  Here they found that
Captain Ramblethorne had engaged a room, but the manager showed them a
telegram that had just reached him.

"Took wrong train cancel room arriving to-morrow morning Ramblethorne."

"A blind," mentally ejaculated Ferret.  "He has been warned."

The telegram had been dispatched from Shrewsbury.  Ferret was again at
fault, for the mistake was a genuine one.  It so happened that the two
trains left Wellington at precisely the same time, the one for
Bridgnorth starting from a side platform.  Before he realized his
mistake Ramblethorne found himself well on the way to Shrewsbury, for
the train stopped at no intermediate station.

"Shrewsbury, as hard as you can go!" ordered Hawke, addressing the
chauffeur.

At a pace averaging fifty miles an hour the powerful car bounded over
the road.  Without mishap it gained the outskirts of the county town of
Shropshire, when an involuntary halt occurred.

It was on the English Bridge, a comparatively narrow structure crossing
the Severn.  A belated drover was driving a herd of refractory cattle
into the town when a motor-bicycle whizzed down the hill.

The cattle stampeded.  With a jerk that almost threw Ferret and Vernon
from the seat, the car brought up.  At the same time the motor-bicycle
slowed down, and dexterously avoiding a huge bullock, glided past the
stationary car.

The moonbeams shone directly upon the rider's face as Ross thrust his
head out of the window.  The motor-cyclist was Ramblethorne the spy.

The recognition was mutual.  The spy, cool and collected, gave no sign
of recognition.  The next moment he was travelling "all out" along the
Much Wenlock road.

"That's Ramblethorne!" exclaimed Ross excitedly.

"Botheration take him!" ejaculated Ferret.  "Are we to get no rest
to-night?"

He opened the window in front of him.  Hawke was sitting with the
chauffeur.  Quickly the detectives arrived at their decision.

"After that chap!" exclaimed Hawke, addressing the chauffeur; "that
motor-cyclist who has just passed.  Ten pounds if you overhaul and stop
him."

It was the bright moonlight that had tempted Ramblethorne to go for a
midnight ride.  He was a keen out-of-door man.  He could handle almost
any make of car or motor-cycle with the utmost skill.  Finding himself
at Shrewsbury, he hired a motor-cycle from an agent, intending to have
a run along the road following the banks of the Severn as far as
Ironbridge.  It was his practice, whenever in a strange place, speedily
to become conversant with the locality.  It was, in fact, part of his
training as a spy.

Ramblethorne was somewhat taken aback when he saw Ross's face in the
moonlight, although he betrayed no sign of surprise.  In an instant he
realized that, by some means, young Trefusis had escaped from U75;
more, he was with a party of men evidently hard on his track.

Quickly he made up his mind.  His career as a medical officer to the
British Service was ended.  He could no longer hope to serve the German
Government in that direction.  Before morning a hue and cry would be
raised.

As he swung along the broad, level road he thought out his plans.  He
would ride as hard as he could until his supply of petrol gave out--a
matter of about seventy or eighty miles.  Then he would abandon and
hide the motor-cycle, and make his way on foot to the Essex coast.
There, he had means to get on board a nominally British fishing-boat,
which would run him over to a Dutch port.

Although the motor-cycle was travelling at close on forty miles an
hour, Ramblethorne glanced back over his shoulder.  He hardly expected
to be pursued.  If the car had turned to attempt to overhaul him, it
would almost to a certainty take the wider of the two fork roads--that
leading to Wellington.

Disagreeably surprised, the spy saw the two powerful head-lights of the
car less than a mile behind him.

The chauffeur of the pursuing vehicle had set his heart on winning the
promised guerdon.  "All out" the car bounded along the road, leaving in
its trail a dense cloud of dust that slowly dispersed in the moon-lit
air.

Hanging on desperately to the sides of the swaying car, Ferret and the
two lads knelt upon the front seat of the coupe and peered through the
dust-flecked glass at the solitary motor-cyclist in front.  They were
gaining--rapidly at first, but now the gap between lessened almost
imperceptibly.

At that tremendous rate, the bursting of a tyre would result in
complete disaster, yet not one thought did the pursuers give to the
danger they were running.  Their sole attention was centred upon the
spy.

A sharp bend close to the village of Cressage enabled the car to get
within fifty yards of the motor-cyclist.  Hawke drew a revolver from
his pocket.  The chauffeur noticed the action out of the corner of his
eye.  Purposely he toyed with the sensitive steering-wheel, causing the
car to swerve erratically.

"Put it up, sir!" he exclaimed, shouting in order to make himself heard
above the roar of the wind over the screen.  "If you bring him down
we'll smash up on top of him before we can pull up.  We'll have him on
Harley Bank right enough."

A sharp run down through the village of Harley brought the car within
sight of a very steep hill, up which the road wound like a silver
thread against the black slope.  This was Harley Bank, one of the
steepest of many stiff Shropshire hills, its gradient averaging one in
seven.

Up mounted the motor-cycle.  Ramblethorne was attempting to take it on
high gear.

The chauffeur of the car took no risks.  He promptly dropped into
second gear, with the result that the gap between them increased to
nearly a hundred yards.  Then the motor-cycle began to falter.  Perhaps
Ramblethorne was not thoroughly acquainted with the mechanism of the
two-speed.  By the time he got the friction-clutch into action the car
had more than regained the lost distance--and the fugitive had not yet
reached the stiffest part of the hill.

"Head him off--jam him up against that bank!" ordered Hawke.

"What for, sir?" asked the chauffeur.  He had no objection to taking
part in a midnight chase, but his sense of prudence told him that it
was not advisable to deliberately smash up another vehicle.

"He's a spy," replied Hawke.  "Don't hesitate.  I will take all risks."

Fifteen seconds later the near front wheel of the car was abreast of
Ramblethorne's back wheel.  Hawke leant sideways with the intention of
gripping the motor-cyclist by the collar, since the relative speeds
were practically the same.  At the same moment the car edged a little
closer to the left-hand side of the road.

Ramblethorne realized the danger.  A collision would with almost
certainty result in his receiving a broken neck; capture meant
ignominious death at the hands of a firing-party.  There was yet a
third alternative--a dash for safety.

He threw out the clutch and applied both brakes, at the same time
bringing the motor-cycle on to the grassy bank.  He alighted on all
fours, but almost immediately regained his feet.  The car was already
twenty yards on ahead and still in gear.

He grasped his cycle by the handle-bars and raised it from its
recumbent position.  One look showed that the glancing impact had bent
the front forks.  The machine was no longer rideable.  Without
hesitation he sprang up the bank.  As he did so he heard the footfalls
of his pursuers.

"Be steady!" cautioned Ferret, as Ross and Vernon alighted from the
car.  "He may be armed.  We're the people to take the brunt of it--not
you."

They were now within a few feet of the summit of the road, which at
this spot ran through the hill by means of a cutting.  Close by were
three excavations.  Someone had evidently attempted to commence
quarrying there, but had abandoned the undertaking.  As far as the
detective could conclude, these pits formed the only possible
hiding-place in the vicinity.

"Hist!" exclaimed Hawke, holding up one hand to enjoin silence.

All was still.  No sound of stealthily retreating footsteps reached
their ears.  Hawke knelt down and placed one ear to the ground.

"Someone breathing pretty hard," he whispered.  "He can't be very far
away; in one of these holes most likely.  Perhaps he's hurt himself."

An investigation of the first possible hiding-place produced no result.
At the second Ross heard a long-drawn sigh, emanating from a patch of
bushes and tall grass.

"Here you are!" he exclaimed.

The place was in shadow, yet he could discern some dark object lying at
full length in the midst of the grass.

In a trice the two detectives threw themselves upon their prey.  For an
instant the man struggled wildly.  Ross and his chum joined in the
fray, each hanging on desperately to his plunging legs.  Ignominiously
he was dragged from his place of concealment into the bright moonlight.

Ferret was the first to give a gasp of astonishment.  Their victim was
not Ramblethorne the spy, but a powerfully built tramp, who, finding
himself released, began to expostulate with alarming vehemence.

"Stop that!" exclaimed Hawke authoritatively.  "We are police officers.
If you don't behave we'll take you in charge for sleeping out without
visible means."

The fellow, cowed into silence, slunk away.

"Confound it!" ejaculated Ferret.  "We've let Ramblethorne slip away
under our very noses.  He'll be clear by this time."

"I'm afraid so," agreed Hawke ruefully; then turning to the chauffeur
he told him to drive into the nearest village, which happened to be
Much Wenlock.

Here Ross and Vernon were able to secure a room at an inn, while the
Scotland Yard men were busy at the little police station, getting a
description of the spy issued through the countryside.

Next morning the lads set out on their return journey to Killigwent
Hall.




CHAPTER XV

The Admiral Works the Oracle

"Look here, old man; what do you say about having a shot for the Naval
Reserve?" asked Ross.  "In ordinary circs I would be prepared to go
through Sandhurst, but this isn't ordinary circs.  Before we pass out,
the war will be over perhaps."

"I'd rather like to see something of the fun," agreed Vernon.

"As if we hadn't already," added his chum.  "But I know what you mean.
Instead of being cooped up in an unterseeboot and hunted by our
fellows, we want to have a hand in rounding up the German submarines.
I vote we write to our respective governors about it."

This conversation occurred two days after the lads' return to
Killigwent Hall.  They had been given up as lost, and their unexpected
return had caused unbounded rejoicings.  Pressmen thronged the Hall to
gather "exclusive" information of the manner of their seemingly
miraculous rescue, but both Ross and Vernon were determined not to
satisfy outside curiosity.  They even kept the story of how the white
flag fluttered down from the signalling mast of U75 from their
immediate friends.

"It will take a long time for us to get a reply," objected Vernon.  "By
the time the letters hang about at the G.P.O., before they are sent to
the fleet, a week will elapse, and before we get a reply bang goes a
whole fortnight.  Let's get hold of a Navy List and see what the
qualifications are."

A careful perusal of the regulations resulted in a setback.  Midshipmen
in the R.N.R., they found, had to be between 16 and 18 years of age,
and must either have passed through a course of instruction for two
years on board an "approved" training ship, or else one year on board a
first-class British merchant ship.

"That's put the hat on it," declared Ross.

"One minute," interposed Vernon.  "Why not write to Admiral Garboard?
He's an old shipmate of my governor's, and I know he's a bit of a pot
up at Whitehall, although he's on the Retired List."

"He was with my pater in the old _Rhodaphlare_ on the China station,"
added Ross.  "We'll try; the wheeze might work."

Accordingly Vernon wrote to the Admiral, who lived about twenty miles
from Killigwent Hall.  Promptly came Sir Peter Garboard's reply:


"TRELANGKERRICK,"
  CORNWALL.

"DEAR VERNON,

"In reply to your letter I am sorry that I cannot help you in the
matter to which you refer, unless you and your friend can produce
sufficient evidences of qualifications for the desired posts.

"On principle I object to influence in any shape or form.  Entry into
any branch of the Service should, like promotion, depend solely upon
the aptitude and ability of a candidate.  This has been my standpoint
throughout the whole of my career, and I see no reason why I should now
depart from it.

"If, however, you think you have strong reasons for pressing your
claims, and you care to see me, we will go more fully into the matter.

"Believe me,
  "Yours faithfully,
    "PETER GARBOARD."


"Not so dusty," commented Ross.  "He does leave us a loophole, although
I'm afraid we'll have to blow our own trumpets.  I vote we cycle over
at once.  We'll catch him in just before lunch."

"Better wait until after he's had his grub," said Vernon.  "That's
always the time to get a man in a good humour."

"We'll risk that," declared young Trefusis.  "Come on."

It was a very hilly twenty miles run across the moors to
Trelangkerrick.  Starting at ten in the morning it took the lads two
hours and a quarter, in the face of a strong south-westerly breeze, to
cover the distance.

Half-way up the drive, they saw the Admiral and a companion emerging
from a path leading from the kennels.

"Hulloa!" exclaimed Sir Peter cordially, as he recognized Vernon Haye.
"So you haven't marked time in coming to see me.  This is young
Trefusis, I presume?  Glad to meet you.  Knew your father very well
back in the 'eighties.  Hope to renew the acquaintance soon, you know.
If it hadn't been for the war----"

Admiral Garboard had taken Trelangkerrick only since the declaration of
hostilities; consequently he had had no opportunity of meeting Admiral
Trefusis, who, since July of the previous year, had been continuously
"somewhere in the North Sea".

"Cecil, my boy," he continued, addressing his companion, a tall,
sunburnt man, in shooting garb although his clean-shaven features and
slightly rolling gait proclaimed him to be a sailor.  "Let me introduce
the sons of two of my old shipmates to you.  Ross Trefusis and Vernon
Haye--my nephew, Cecil Bourne.  You'll stay to lunch, of course.
Cecil's on three days' leave.  He's not satisfied with hunting German
submarines, but must needs go after my rabbits."

They walked towards the house, Ross and Bourne leading, and the Admiral
and Vernon bringing up the rear.

"We'll discuss this little matter after lunch, my boy," remarked the
Admiral.

The meal proceeded without a hitch, the Admiral in his breezy way
relating anecdote after anecdote of the Service in the good old days.

"By the by," he remarked, "what's this yarn I hear about your
neighbour, Dr. Ramblethorne?  There's a report that a warrant has been
issued for his arrest."

"For espionage, I believe," replied Vernon.

"Bless my soul!  Is that a fact?  One doesn't know whom to trust in
these days.  No details, I suppose.  A decent fellow, too, from what I
saw of him.  No, I don't think you've met him, Cecil, at least not
here.  By the by, you might tell the boys about your little adventure
up-Channel in the _Tremendous_."

Ross and Vernon turned very red in the face, but as they sat with their
backs to the window the change of colour passed unnoticed.

"Oh, that submarine business!" remarked Lieutenant Bourne modestly.
"Just an ordinary occurrence, don't you know, except for one thing.  I
was officer of the watch at the time.  We spotted a strafed
unterseeboot flying a white flag.  Have to be jolly careful, you see.
Either give the thing a wide berth, and wireless the destroyers to take
possession of the prize, or else cut the brute in two.  Anyhow,
something funny did happen.  There were two fellows in mufti standing
close to the skipper on the submarine's deck.  Goodness only knows why
they did it, but I saw one of them----"

"Cut the halliards and let the white flag down," interposed Vernon.

There was dead silence in the room.  Only intense excitement was
responsible for young Haye's lapse of manners.  The words had slipped
from him almost unconsciously.  Ross barked his shin as a gentle
reminder.

"By Jove!  How did you know that?" demanded Bourne.  "Shouldn't have
thought that the yarn had had time to travel very far.  Hope I haven't
been boring you?"

Vernon took his courage in his hands.

"It was Ross who cut the halliards," he announced.  "We were both on
board, and jumped overboard just in time, and got hold of a lifebuoy
dropped from the _Tremendous_ as she passed."

"By Jove!" ejaculated the Lieutenant.  "I am surprised.  I wondered
whether you were picked up.  It was a jolly plucky action.  But how did
you get on board the unterseeboot?"

"Aye, out with it!" added the Admiral.  "I heard that you were missing,
of course, and also of your return.  Truth to tell, I thought when I
got your letter that the pair of you had been acting the goat, and had
run away to sea and had thought better of it."

"We didn't run, sir, we were carried," explained Ross.  "And Dr.
Ramblethorne was responsible for it."

Admiral Sir Peter Garboard was not satisfied until he had heard the
complete story of his young friends' adventures.  When they had
finished he turned to his nephew.

"Young Haye and his chum came to see me on a private matter," he
remarked, "but I don't think they will object to your hearing what we
have to say."

"Are you quite sure you won't?" asked Bourne, addressing the lads.

"Both Trefusis and Haye are supposed to be going in for Sandhurst,"
continued Sir Peter.  "Although, candidly speaking, I don't see why a
naval man should want to put his son in the Army."

"In my case it is only following a family precedent," said Ross.  "For
generations back the eldest son has alternately been in the Navy and
Army."

"And in my case it is the force of circumstances," added Vernon.  "When
I was of the age to be sent to Osborne I was a puny little chap.  The
doctor wouldn't pass me."

"You've altered a bit since then, I can see," remarked Bourne.  "You
look as strong as a young horse now."

"Yes, I've grown out of my early ailments, I think," said Vernon.

"Pity the doctor hadn't passed you," said Sir Peter bluntly.  "Ten or
eleven is too young an age for any medical man to express a final
opinion upon.  I remember a fellow in the Service who was nearly blind
on one eye and almost as deaf as a post.  He got through the
medical--influence, I expect.  Anyway the Navy was none the worse for
it.  You'll remember him by name, Cecil: he was my secretary on the
China Station.  Funny thing about him was that he couldn't see to read
red figures unless he looked through a green glass.  Do you know that
when I received your letter I imagined that your temporary
disappearance had something to do with your running away to sea?"
reiterated the Admiral.  "The idea, I believe, comes to most boys
almost as a matter of course; something like measles, in fact."

"Well, now we've had a taste of submarine work, we feel that it is high
time we had a hand at helping to collar the German unterseebooten,"
explained Ross.

"I think it could be arranged," remarked the Admiral.  "You haven't had
actual experience, of course----"

"Eh!" exclaimed Bourne.  "By Jove, Uncle, I should say they had!"

"From a strictly professional standpoint, I ought to have said, only
you didn't give me time," added Sir Peter.  "I'll write off to the
Admiralty to-night and see if I can get you both into the R.N.R.  You
are too young to receive commissions as Sub-lieutenants, but no doubt
you can be taken on as midshipmen.  Stringent regulations go by the
board in war-time.  Isn't that so, Cecil?"

"They would probably be appointed to an armed liner for patrol duty,"
observed Bourne.  "There are, I believe, no midshipmen on the trawlers
and motor-boats in submarine-hunting."

"We must take what we can get," said Vernon, "but we would rather----"

"Yes, yes," interrupted the Admiral.  "I know.  You leave that to me."

Accordingly Ross and Vernon "left it to" the genial Sir Peter, with the
result that within a week they were specially appointed as temporary
midshipmen to the motor-patrol ship _Capella_.




CHAPTER XVI

H.M.S. "Capella"

With the least possible delay the two chums joined the _Capella_ at
Southampton.  She was one of an entirely new class of vessel, built for
the express purpose of ridding the high seas of the presence of the
modern pirates.  Looking at her as she lay in the Empress Dock, there
was little about her to attract the eye.  A raised fo'c'sle and poop,
and a low superstructure abaft the funnel, two stumpy masts and
grey-coloured "wall" sides, gave her the appearance of a trawler.  It
was only when one had an opportunity of seeing her in dry dock, where
her graceful under-body, with its fine "entry" and clean run aft, was
visible, that any idea of her speed could be arrived at.  Further
details would be undesirable.  Sufficient to add, to quote a Yankee
journalist who had been given an opportunity of paying a visit to the
Grand Fleet and inspecting the component units of the greatest armada
that the world has yet seen, the class to which she belonged were "some
boats".  The exigencies of the hitherto unprecedented method of
carrying out the naval side of the Great War had demanded the creation
of large flotillas of small motor-driven hornets.  In the initial
stages the want was temporarily supplied through the patriotism of
owners of private motor-boats.  These craft, good in their way, were
handicapped by a lack of uniformity.  Nevertheless they served as an
excellent training-school until the Admiralty with remarkable celerity
produced the novel type of craft to which the _Capella_ belonged.

The _Capella_ carried a large crew in proportion to her size--four
officers and twenty-four men.  Her skipper was Stanley Syllenger, who
held the rank of Lieutenant-Commander, R.N.R.  He was a big, bluff man
of about thirty-five, a strict disciplinarian, and a stickler for duty.
He could be very outspoken when he wanted, which was fairly frequently,
but withal he was of a thoroughly good-natured disposition.

There were two Sub-lieutenants, R.N.R.  The senior was John Barry, a
very mild type of young officer.  He usually spoke in a very soft
voice, except when occasion warranted, when he could bellow in a way
that would take a stranger entirely by surprise.  It seemed incredible
that such a bull voice could belong to such a dapper little man as John
Barry.

The other Sub was Noel Fox--a tall, deep-chested fellow of twenty,
boisterous, and full of spirits.  In five crowded years he had gained a
good knowledge of three oceans, and a nodding acquaintance with the
remaining two.  Beginning his career on board a five-masted sailing
ship, he had served in tramps, "intermediates", and mail steamers until
the outbreak of the war, when he found himself appointed to an armed
liner that abruptly terminated her existence by trying conclusions with
a German mine.

Captain Syllenger and Sub-lieutenant Barry were pacing the diminutive
quarter-deck of the _Capella_ as she lay alongside the quay.  The
skipper had heard officially that morning of the appointment of two
temporary midshipmen to the craft under his command.  "Hanged if I can
understand it, Barry!" he exclaimed in his outspoken manner.  "What's
the idea of turning the _Capella_ into a nursery, I should like to
know!  These youngsters are somebody's pigeons, I suppose.  The usual
yarn.  Influence up topsides does the trick, and we're saddled with two
raw lubbers."

"There is no mention of their having had previous sea-service, sir?"
remarked Barry.  "But perhaps they'll turn out fairly smart."

"They will," added the Lieutenant-Commander grimly; "that is, if I have
anything to do with them for any length of time.  But, by Jove! here
they are, unless I'm much mistaken."

Looking rather self-conscious in their brand-new uniforms, Ross and
Vernon doubled down the steeply sloping gangway.  As they came aboard,
Syllenger noted with professional satisfaction that they both saluted
the quarter-deck.  The action showed, by one thing at least, they were
not the greenhorns he expected to receive.

"You have had no previous experience, I believe?" he asked, after the
midshipmen had introduced themselves.

"Very little, beyond knocking about in yachts and boats," replied Ross.

"That's something," decided the skipper.  "A fellow who starts his
career in a small boat has the makings of a good seaman.  It is rare
indeed that a man who goes straight to sea in a steamship makes a smart
man in a boat.  If ever you go on patrol duty you'll find your
experience of value.  By the by, I suppose you know our particular job?"

"Yes, sir," replied Ross.  "Hunting submarines."

"Ever seen one?" asked Syllenger abruptly.

"Several of the D and E classes manoeuvring in Plymouth Sound."

"But a German one?"

"Yes, sir."

"Where?"

"We've both spent nearly a week on board an unterseeboot, sir."

The skipper sternly regarded the two midshipmen.

"Look here," he said.  "If you think you've come on board to gammon me,
the sooner you get that idea out of your heads the better.  There's no
room on the _Capella_ for a pair of modern Ananiases."

Ross said nothing.  From the outside left breast-pocket of his
"undress" coat he produced a white foolscap envelope, bearing in blue
the "foul anchor" badge of the Admiralty.

The Lieutenant-Commander took the proffered envelope somewhat
suspiciously.  He more than half expected that it was a letter of
introduction from a high official at Whitehall, on the strength of
which the two midshipmen felt inclined to "put on side".

Instead, he found that it contained an autograph letter from the
Admiralty, thanking the lads for their bravery and presence of mind,
whereby they materially assisted in the preservation of H.M.S.
_Tremendous_ and in the destruction of two of the enemy submarines.
The document finished by congratulating Ross and Vernon on their escape
from U75, and trusted that their career as midshipmen of the R.N.R.
would be marked with success.

Syllenger read it through carefully and slowly, deliberately returned
it to the envelope, and handed it back to Ross.  Then he held out his
hand.

"I'm sorry for what I've said," he declared simply.  "Forget it, if you
can.  Come and lunch with me at one bell."

"Thank you, sir," replied Ross in answer to the invitation; then, after
a pause, he added: "we didn't want to brag about it, but you made us."

"So I understand," said the skipper.  "I've misjudged the pair of you,
but the least said about my part of it the better, I fancy."

He hailed a couple of men, instructing them to strike the midshipmen's
luggage down the companion-ladder.  Ross and Vernon followed, to be
introduced to their new quarters.

Owing to the _Capella's_ shallow draught, the cabin space was rather
limited.  The Captain's quarters were a double cabin, comprising a
state-room and sleeping-room, in a deck-house under the bridge.  The
two Subs had each a small "dog-box", as they termed it, aft on the
starboard side.  The engineer had a similar cabin on the port side.
Adjoining his quarters was another cabin, which had hitherto been used
as an overflow receptacle for officers' luggage.  This had now been
cleared out, and hooks provided for the two midshipmen to sling their
hammocks.  The slinging and unlashing of the hammocks was performed by
a servant, to whom Ross and Vernon had each to pay ten shillings a
month for the privilege.  During the day the cabin made a fairly
comfortable room, although the furniture was Spartan-like in its
simplicity.

At six bells (11 a.m.) the _Capella_, having replenished her fuel and
stores, and made good slight defects, was "tracked" out of the dock.
An hour later she left Southampton, bound for a rendezvous off Beachy
Head, near which a U-boat had been reported to have made an
unsuccessful attack upon a swift merchant vessel.

The run down Southampton Water was necessarily performed at
quarter-speed, for in spite of her light displacement the _Capella's_
wash at full speed was almost equal to that of a liner.  Even as it
was, a long line of white foam lashed itself upon the mudflats several
minutes after she had passed.

When Calshot Castle was abreast, speed was increased to 30 knots.
There was an easterly breeze blowing against the ebb-tide, with the
result that quite a choppy sea was met with outside Southampton Water.
Like a knife, the sharp cutwater of the _Capella_ cleft the waves,
sending up showers of white spray; but such was her speed that, before
the wind could carry the spindrift on deck, the swift vessel was beyond
the cascade of foam.  She hardly felt the motion of the waves; indeed,
she was so steady that it was possible to place a pail of water on deck
without any of the contents being spilt by the "lift" of the ship.

Under the guidance of Noel Fox, the midshipmen made the round of the
vessel, the Sub explaining everything to them in detail.  Already the
lads had taken a great fancy to the Sub, and Fox reciprocated the
sentiment.  He had a way about him that enabled him to give particulars
of the most intricate mechanism without having to resort to dry,
parrot-like instruction.

By the time he had explained the ingenious devices used to entrap the
German unterseebooten, Ross and Vernon felt inclined to marvel how it
was they found themselves on board the _Capella_, since only sheer good
luck had saved U75 from being doomed during every hour of their brief
and involuntary detention.

"Yes, we can mop up the German submarines quicker than they can turn
them out," said the Sub.  "Of course I don't mean to say that a few of
them won't get a smack at some of our ships for some time to come; but
all the same we are giving them beans.  From a strictly professional
point of view we would be sorry if Old Turps abandoned his 'effectual'
blockade.  Our chances of having a high old game with the
unterseebooten would be considerably reduced."

"There are still some in the English Channel," hazarded Vernon.

"Yes, a few; but have you noticed how those fellows fight shy of Dover?
They shun it like the plague.  It's horribly unhealthy for them.  D'ye
know why?  Perhaps you wouldn't have paid much attention to it, but
some months ago the Admiralty issued a 'Notice to Mariners', stating
that the Straits of Dover were heavily mined, and that all shipping was
to pass through the Downs within three miles of the Kentish coast.

"So it's fairly safe to assume that the few stray unterseebooten that
are still lurking in the Channel have made the passage round the north
coast of Scotland.  It's only a matter of time before we bag the lot, I
fancy."

"And our submarines?" enquired Ross.

"Have fewer opportunities since the Hun battleships and cruisers have
such a decided inclination to remain in harbour," rejoined Fox.  "When
there's a chance, you can bet your bottom dollar that our fellows seize
it.  Quite recently one of our submarines found herself alone and
disabled in the Bight of Heligoland.  Undismayed, her
lieutenant-commander signalled to a passing German trawler, covered her
with his guns, and made the Hun tow the crippled submarine into British
waters.  Then he released his involuntary benefactor, but before so
doing can you guess what he did?"

"No," replied both lads.

"Made the Huns line up on deck and sing the 'Hymn of Hate'.  You can
imagine the surprise of the trawler's men, who, judging by the
treatment meted out to our fishermen by the German submarines, expected
nothing less than imprisonment and the loss of their boat.  But it's
close on one bell," remarked Fox at length.  "You're messing with the
skipper to-day, I believe.  He's quite a decent sort when you know him
properly, but it takes a bit of doing."

A seaman strode up to the bell and gave it a sharp stroke.  Just then a
messenger hurried from the diminutive "wireless" room abaft the
chart-house and, leaping down the ladder at a single bound, knocked at
the door of the Captain's cabin.

"Stow those things away, Sparkes," exclaimed Captain Syllenger.  "Lunch
will have to wait."

He dashed out of his cabin.  On the way to the bridge he passed Fox and
the two midshipmen.

"You'll have to tighten your belts, my lads," he announced.  "We've
just had a message through.  A strafed unterseeboot has been spotted
trying to get into Spithead.  If we don't nab her within half an hour,
I'll eat my hat!"




CHAPTER XVII

A Double Bag

It was a sea-plane, flying at fifteen hundred feet above the Warner and
The Nab Lightships, that had detected an elongated shadow creeping
stealthily over the shingly bottom close to the Dean Tail Buoy.  The
shadow was that of a German unterseeboot, since none of the British
submarines were known to be in the eastern approaches to Spithead.
Evidently she had gone out of her course, for instead of being in the
main channel she was well to the north of it.  More than likely the
strong east-going tide, which hereabout surges at such a rate that it
causes the shingle 30 or 40 feet beneath the surface to emit a deep
rumble, had taken the unterseeboot in its grip.

Promptly the sea-plane wirelessed the news, and quickly a "general
call" was sent to the patrol vessels in the vicinity.  The _Capella_
was one of the craft that picked up the welcome order.

She was now only seven sea miles distant from the Dean Tail Buoy.
Within ten minutes of the receipt of the wireless she was on the
spot--one of the very first of a regular hornet flotilla bent upon
adding yet another of Von Tirpitz's pets to the "bag".

For the next quarter of an hour it looked as if a novel kind of marine
waltz was in progress.  Nearly a score of swift vessels were executing
fantastic movements at full speed, circling and interchanging positions
until it seemed as if collisions were impossible to avoid.

Their object was to thoroughly bewilder the already doomed U-boat, for,
if possible, her capture in a practically intact condition was desired.
In very deep water, salvage of a sunken submarine was out of the
question; here, in a comparatively shallow depth, and close to an
important naval base, to which the prize could be taken with little
trouble, the opportunity for capture rather than instant destruction
was too good to be missed.

Suddenly a cloud of white smoke shot up from the sea.  Its appearance
was greeted by hearty cheers from the patrol vessels.  It was a signal
that the U-boat, in her attempt to find deep water, had floundered
blindly into the trap.  Over and over again the hunters passed, towing
non-explosive grapnels, until it was certain that the prey was helpless
in their toils.

Then, in obedience to an order from the senior officer, the swift
vessels withdrew for nearly three cables' length from the spot where
the boat lay.  Two slow but powerfully engined trawlers approached at a
cable's length abreast, towing the bight of a massive steel hawser
between.  Doing little more than drift with the tide they crept past
the submerged U-boat, one on either side of the mark-buoy that
indicated her position.

Presently the strain on the hawser increased.  It was only by making
full use of the twin-screws that the trawlers were able to prevent
themselves from swinging together.  The steel rope stretched until it
resembled two metal bars which bore silent testimony to the strain.

Just then the two vessels shot ahead.  Although the hawser was still
intact, it no longer took any strain.  But its work was done.  The
bight, engaging the conning-tower of the unterseeboot, had turned the
submarine on its side.  In the space of a few seconds the deadly fumes
from the capsized batteries had almost painlessly accounted for the
crew of the U-boat, who themselves had neither pity nor consideration
for the hapless victims, men, women, and children, massacred against
all dictates of humanity and convention of civilized warfare.

"A bit of work for the dockyard lighters to-morrow," commented
Sub-lieutenant Barry, as the _Capella_ parted company to resume her run
up-Channel.  "They'll raise the U-boat, and take her into dry dock,
before the sulphuric acid has had time to do much damage to her
mechanism."

"I shouldn't be surprised if there were another U-boat knocking
around," remarked Vernon.  "From our limited experience we know that
they work either in pairs or threes."

"Then the worse for them," rejoined Barry.  "It would be a great wheeze
to bag two of them in one day.  Desperate diseases need desperate
remedies, you know."

Therein the Sub voiced the unanimous opinion of the British Navy.  At
the commencement of the war, the torpedoing of several battleships and
cruisers by German submarines aroused no enmity within the hearts of
the British tars.  They realized that a warship is "fair sport" to the
submarines of the opposing side.  To run the risk of being blown up was
one of the excitements to undergo in the course of duty.  But when it
came to torpedoing helpless merchantmen, and jeering at the
death-struggles of the unfortunate crews, Jack Tar began to regard the
unterseebooten in the light of pirates and murderers.  The wanton
destruction of the _Lusitania_, accompanied by the appalling death-roll
of non-combatants, women and children, literally sounded the
death-knell of the crews of von Tirpitz's jolly-Roger-flying
submarines.  In their methods of "frightfulness" they had overreached
themselves.  They had sown a wind: they were now reaping a whirlwind
with a vengeance.

And now the great silent Navy was paying back von Tirpitz in almost,
but not quite, his own coin.  While the much-advertised blockade of
Great Britain was petering out, British submarines were playing havoc
with German shipping in the Baltic--a sea which the Teutons regarded as
being almost their very own.  Yet what a difference marked the methods
adopted by the humane commanders of our submarines when dealing with
German mercantile shipping.  A punctilious regard for the safety of the
crews of overhauled merchantmen won admiration even from the seamen of
the destroyed vessels.  Humiliation and reproach seemed to haunt the
white-bearded dotard, whose hands had sought in vain to wrest the
trident from Britannia's virile grasp.

At about five in the afternoon the _Capella_ arrived at her station off
Beachy Head, relieving her sister ship the _Markab_, that, with three
other motor-driven craft, had been engaged in a vigorous, but for the
most part uneventful, patrol.

Day and night for a fortnight at a stretch, unless anything unforeseen
took place, the _Capella_ was to cruise up and down, keeping a smart
look-out for any sign of an object resembling a hostile periscope.  In
order to economize her fuel supply her speed was reduced to 10 knots.
It was then that her bad qualities showed themselves.  With her shallow
draught and high freeboard she rolled like a barrel, since speed was
essential to impart steadiness.  The motion was certainly
disconcerting, although it did not imply that the _Capella_ was
unseaworthy.

"'Fraid our chances of bagging another U-boat to-day are off," remarked
Barry to Ross.

It was within half an hour of sunset.  The chums had been temporarily
separated.  It was Vernon's "watch below".  The senior Sub and young
Trefusis were on the bridge.  In spite of the still-prevailing east
wind it was a grand evening.  Three miles away, broad on the starboard
beam, the chalk cliffs known as the Seven Sisters were beginning to be
tinted by the crimson hues of the western sky.  To seaward, three large
vessels were in sight.  One, a liner bound down-Channel, was pelting
along at such a pace with the wind that the smoke from her funnels was
rising almost perpendicularly.  Forging ahead in the opposite direction
were two big tramps, the smoke from their funnels, beaten down by the
strong breeze, trailing across the surface of the water for a couple of
miles in their wake.

"An object lesson," remarked Barry.  "The arteries of the Empire.  Hang
it all!  The blockade reminds me of a pigmy treacherously stealing up
behind a giant and trying to cut his jugular vein.  Instead, he merely
scratched a comparatively unimportant capillary, and feels mighty sorry
for himself when the giant turns and scruffs him by the neck."

Leaning over the bridge-rails, the Sub startled his companion by
bellowing in a voice loud enough to be heard a mile away:

"On look-outs!  Stand by bow and stern lights!"

The _Capella_ was making preparations for the night.  Unlike the armed
merchantmen that are compelled to scour the North Sea, summer and
winter alike, without showing the faintest glimmer of a lamp, the
_Capella_ observed the rules and regulations for preventing collision
at sea.  Her port, starboard, and bow lamps were lighted by
electricity, but, in order to guard against possible break-down of
current, oil lamps had also to be trimmed and lighted, ready, should
occasion serve, to take their places.

It was part of Ross's duty to report to the officer of the watch that
these lamps were in order, and also, at regular intervals, that the
navigation lights were burning brightly.

Presently the Sub prepared to take a cross-bearing.  He was fairly
certain that the _Capella_ had reached the westernmost limit of her
patrol-ground.  From that point she was to proceed due south for 10 sea
miles, and then due east for 20 miles until she fell in with her
"opposite number".

While Barry was thus engaged, Ross noticed a sail about 2 miles distant
on the starboard quarter.

"By Jove!" he muttered as he brought his glass to bear upon the
stranger.  "That's a funny rig."

The craft was a "two-sticker".  She was square-rigged on the foremast,
carrying fore-topsail and fore-course.  No jibs were set; neither, as
far as he could see, was any sail set on the mainmast.  The vessel's
sides were painted green with a broad red band.

Even as he kept the craft under observation she starboarded her helm,
shaping a course that would converge upon that of the rearmost of the
two tramps.  By so doing she exposed a considerable portion of her
broadside.

Ross gave an exclamation of astonishment.  Above the green sides
appeared what was undoubtedly the conning-tower and housed periscope of
a submarine.  "Submarine on the starboard quarter, sir!" he reported.

"What!" exclaimed Barry, levelling his telescope.  "By Jove, yes!  What
luck!"

The unterseeboot had, of course, noticed the _Capella_, and had
mistaken her for a trawler.  She realized that she ran a risk in case
the latter might be armed, but, trusting to her disguise, she hoped to
get within torpedo range of the tramp--a vessel of over 3000 tons--sink
her, and make her escape in the confusion that was bound to ensue.  On
the other hand, her Kapitan had good reasons for thinking that the
supposed trawler was not one of the armed patrol, since they usually
worked in company.  By rigging canvas bulwarks and setting sail upon
dummy masts, he was able to approach with little fear of detection.

"Action!"

Quickly the _Capella's_ crew were at their stations.  The quick-firers
were loaded, and their screens lowered so as not to impede their arc of
fire.  Until these preparations were complete the vessel still held on
her course.

Then Captain Syllenger, who had come on deck, telegraphed for full
speed ahead.  Like a racehorse the _Capella_ leapt forward.

A double, converging line of white foam marked the track of a torpedo
from the doomed U-boat.  By a slight alteration of helm the _Capella_
avoided it.  The action was hardly necessary: it was merely a matter of
precaution, since the _Capella's_ peculiarities of construction made
her practically immune from torpedo attack.

Captain Syllenger had no intention of ramming his opponent.  Ramming
with a lightly built vessel, such as the _Capella_, would only be
employed as a last resource.

At an almost point-blank range of 400 yards both bow guns were fired
simultaneously.  There was no need for another shot.  One of the
projectiles, hitting the U-boat at the base of the conning-tower, tore
a jagged hole a couple of feet in diameter.  The other shell hit her
about 10 feet from the bows, and, with an erratic peculiarity that such
missiles have after the first impact, was deflected downward, expending
the full force of its explosive charge in the submarine's bow
torpedo-room.

In a moment the luckless U-boat was done for.  A huge column of smoke
marked the spot where she had disappeared like a stone, while flying
pieces of metal hurtled far and wide through the air.  Several of the
fragments clattered upon the _Capella's_ deck as she swung round to
avoid any possibility of fouling debris.  Of the crew not a man was to
be seen.  Those who had not been killed by the shell-fire had been
wiped out by the explosion of their own torpedoes.

"We've pulled off a double event to-day, after all," remarked
Sub-lieutenant Fox as he disappeared down the companion-ladder to
resume his interrupted "watch below".  "Barry has got his wish."




CHAPTER XVIII

The Smoke-signals

For the next ten days nothing occurred beyond the ordinary routine.
Even Ross and Vernon, to whom everything was at first a novelty, began
to feel the irksomeness of the constant and vigilant patrol.  No
hostile submarines made their appearance; there were not even any
reports, true or otherwise, that they had been sighted.  It was the
same all along the English Channel--"nothin' doing".  It seemed as if
the unterseebooten had finally given up these waters as a "bad egg".

Yet it would be most injudicious for the naval authorities to relax
their watchfulness.  Areas of strategic importance must still be
closely guarded, since it was just possible that the wily Teuton would
refrain from submarine warfare in the Channel until the patrol-boats'
crews were lulled into a sense of false optimism.

The only break in the monotony was the occasional and welcome
appearance of a motor-boat from Shoreham, bringing off fresh supplies,
newspapers and letters for the patrol vessels.

Amongst Ross's correspondence was a letter from his father.  Admiral
Trefusis gave no indication of what he was doing, merely a brief
statement that he was still "somewhere in the North Sea".  He
congratulated his son upon his escape, and mentioned that he had heard
from the captain of H.M.S. _Tremendous_ with reference to his son's
action in warning the battleship.  But although the Admiral did not
express himself very enthusiastically on paper, he was as pleased as
only a proud father can be at his boy's display of gallantry and
resource.  "Under the circumstances," he wrote, "I think you did right
in temporarily abandoning your preparation for Sandhurst.  No doubt you
will acquit yourself in your present position as a Trefusis should do.
I was certainly surprised to hear about that fellow Ramblethorne.  He
always appeared to be a really decent man.  It only shows how careful
one has to be when dealing with a highly organized enemy."

Amongst Vernon's batch of correspondence was a letter from
Detective-inspector Hawke.  It was couched in semi-official language, a
survival of days long ago when the Inspector was a budding constable
and had to submit countless written reports to his superiors.

There was, he wrote, no definite news concerning Ramblethorne,
otherwise von Hauptwald.  The local police had taken up the case, and,
assisted by the military, were still scouring the country.  As usual,
there were inaccurate and misleading reports from various parts of the
country.  It was generally accepted that the spy was being hidden by
some of his compatriots who, by indulgence of the British Government,
were still at large in the country, or else that he had succeeded in
getting away on board a neutral ship.

The inquest on von Ruhle had taken place, with the anticipated result,
a verdict of _felo de se_ being returned by the jury.  No evidence had
been submitted as to the dead man's real occupation.  Under the name of
Cornelius Vanderhuit his body was handed over to the authorities for
interment.

But the case did not end there.  It remained for the competent
Authorities to decide the steps to be taken with reference to the
papers that had been found in von Ruhle's possession.

"I am keeping von Ruhle's 'malacca' as a memento," concluded Hawke.
"It may help me to discriminate between it and a portable metal tripod,
and save me from being placed under arrest by the military.
Fortunately, upon the last occasion, I did not meet with my Waterloo."

"The old chap feels a bit sore about it, I can see," remarked Ross.
"He's written a good deal more than he evidently intended.  However, he
looks like 'making good' this time."

"It's a pity Ramblethorne slipped through the detectives' fingers,"
said Vernon, as he prepared to go on deck.  "That fellow's bound to
cause trouble until he's laid by the heels."

It was Noel Fox's "trick".  The Sub was standing on the bridge with his
eye glued to his telescope.  A mile or so inland, on the summit of the
South Downs where they approach Beachy Head, three columns of smoke
were rising in the still air.  There was nothing extraordinary in that.
It might be a farmer burning rubbish on his fields; but what attracted
the Sub's attention was the remarkable and systematic changes in the
density of the smoke.  At one moment the two outside pillars were
heavy, the centre one being little more than a thin haze; at another
the conditions would be reversed.

Fox decided to take action.  Rapidly the _Capella_ closed with the
shore, until she was within signalling distance of a coast-guard
station.

The station in question was not manned by coast-guards.  Not considered
important, its complement was depleted at the outbreak of hostilities,
most of the men joining the large armoured cruisers.  A chief officer
and a boatman alone remained.  These were at a later period augmented
by a party of Sea Scouts.

As soon as the _Capella_ had "made her number", a signaller took up his
position on the roof of the chart-house.

"Fires burning one mile inland to north-west of coast-guard station,"
he semaphored.  "Suspect smoke-signals.  Investigate and report."

Keeping his telescope bearing on shore, Vernon watched the result of
the signal.  Promptly half a dozen Scouts, mounted on bicycles, set off
to the position indicated.  Their progress was hidden by an intervening
clump of trees, but in less than a quarter of an hour they returned.
By this time the smoke had disappeared.  One of their number worked the
semaphore attached to the station.

"Fires made with damp straw.  Found old blankets apparently used to
stifle smoke.  Saw large car stationary; made towards Lewes on
approach; number known; have informed police."

"Smart youngsters!" exclaimed Captain Syllenger.  "They've helped to
nip some little plan in the bud.  We'll have to be jolly careful for
the next few days, I expect.  Did you make a note of the fog-signals,
Mr. Fox?"

"I did, sir," replied the Sub, producing a leaf of a notebook covered
with an unintelligible number of lines.  "Each of these strokes
represents a column of smoke according to its position."

"I can make nothing of it," remarked Syllenger.  "At any rate I'll send
your result to the Admiralty with the utmost dispatch.  Take her in,
Mr. Fox, and bring up where you find the two-fathom mark."

The _Capella_ headed nearer towards the shore, a leads-man sounding
until the required depth was found.  One of the boats was lowered,
manned, and rowed to the coast-guard station, Sub-lieutenant Barry
being in charge, with Ross as his immediate subordinate.

"I want this to be forwarded to the Admiralty with the least possible
delay," he announced, addressing the chief officer.  "How long do you
think it will take to get through?"

"Too late for the eleven something train from Brighton, sir," was the
reply.  "There's a gentleman in the village who has a big car.  He's a
member of the Volunteer Training Corps.  No doubt he'll take it as far
as Lewes.  Why, sir, here's the gent himself!  Mr. Hyde's his name."

The newcomer was a sparely built man of below medium height.  He looked
about thirty years of age.  In reality he was nearly fifty.  Having
vainly attempted to obtain a commission in the R.N.R. and the Army, he
had joined the V.T.C. in the hope that, perhaps, some day his services
might be utilized in a very practical form.  Now his chance was at hand.

He had strolled down to the beach on noticing a boat putting off from
the patrol vessel.

"Lewes?  Certainly," he replied in answer to Barry's question.  "I
doubt whether you'll save much.  Why not let me take the message right
to the Admiralty?  I'd like to do it, 'pon my word I would."

The Sub hesitated.  Perhaps the stranger might be all right; but he
might be all wrong.  One had to be very careful in these times.  Yet
the offer was a tempting one.  If possible, it was most desirable to be
able to decipher the transcription of these mysterious columns of smoke.

"I say, Trefusis," he said, "you've had a fairly long time afloat; what
do you say to a run up to town?  I'm sure this gentleman would make no
objection to giving you a seat in his car."

"With the greatest pleasure," declared Mr. Hyde.

"Thanks!" rejoined Barry.  "Of course the honour of delivering the
letter will be yours, sir.  Mr. Trefusis accompanies you merely as a
passenger.  We'll stand by to pick you up, Trefusis.  I'll make it all
right with the skipper."

The Sub accompanied Mr. Hyde and the midshipman to the garage, which
was about four minutes' walk from the coast-guard station.  While the
man was getting out the car (he was his own chauffeur), Barry seized
the opportunity of telling Ross to be on his guard, in case anything
suspicious occurred.

With a terrific bound the powerful car started on its sixty-mile
journey.  Between the sea and Lewes the needle of the speed-indicator
never fell below 40 miles an hour, until at times the car was running
at 60.  Village after village was passed at almost break-neck speed.
In vain, sleepy rural constables sought to hold up the reckless driver.
Discretion was the better part of valour, so they stood aside and
attempted to note the number on the identification plate of the car.
Again in vain.  All they could see and swallow was a cloud of white,
chalky dust that hung thickly on the sultry air long after the car was
out of sight and hearing.

The hills around East Grinstead it surmounted at 40 miles an hour,
dashing down the inclines at the speed of an express train, and
swerving time after time to avoid lumbering farm wagons.

At Croydon Mr. Hyde wisely slowed down.  He had covered 49 miles in
exactly fifty-five minutes, but twenty-eight minutes later the car drew
up under the Admiralty Arch.

"Room 445 is the one I want," he explained to Ross.  "I know my way
about here, you know.  I've several relations at the Admiralty.  Come
along: the car won't hurt where she is."

"Your pass, sir," demanded a Metropolitan policeman who, with a naval
pensioned petty officer, was stationed at the door.

"Haven't one," replied Mr. Hyde.  "Urgent business--see?" and he
produced the envelope, bearing the words "On His Majesty's Service", in
which was enclosed Captain Syllenger's communication.

The policeman was the essence of imperturbable dignity.

"No use, sir; you must have a pass.  They are obtainable across the
road there."

"It will mean at least twenty minutes' delay," muttered the motorist
savagely, as he turned away.  "Come on, Mr. Trefusis, let's try our
luck across the way."

As Ross descended the short flight of stone steps leading from the
lobby to the street, he nearly cannoned into a couple of naval officers
who were about to enter the building.  Suddenly remembering that he was
in uniform, the midshipman brought his right hand smartly to the peak
of his cap.  As he did so, he recognized that one of the naval men was
his father.

The recognition was mutual.

"Hullo, pater!"

"Hullo, Ross!  What brings you here?  Duty, eh?  It's the same in my
case.  Sorry I can't have you to lunch, but must catch the first train
north.  This is the first time I've come up to town since the war
started.  In any case I'm not sorry that I am not stopping the night
here.  Judging by reports, it's a jolly sight too dangerous for me.
Don't fancy being run over by a taxi in a dark main thoroughfare.  Give
me the North Sea any day.  Well, I must be moving.  Can't keep My Lords
waiting, you know.  Good-bye, Ross!"

It was Admiral Paul Trefusis' way.  Whenever he had any business on
hand that kept him from his ship, he invariably spoke in short, jerky
sentences.  Ross knew his parent's little mannerism.

"One moment, pater," he exclaimed.  "We're in an awful hurry too----"

"Don't look like it," growled the Admiral good-naturedly.  "You were
ambling out like an old shellback.  Always execute orders at the
double: that's my advice to budding midshipmen.  Well, what is it?"

As briefly as possible, Ross told his parent of the rebuff Mr. Hyde and
he had received, and of the matter that brought them at 50 miles an
hour from a remote Sussex coast-guard station.

Making a hurried excuse to his companion, the Admiral skipped up the
steps into the lobby, Ross and his fellow-traveller following closely.

The policeman naturally asked for no pass from a Flag officer in
uniform, but he was on the point of stopping his companions when the
messenger recognized the Admiral as his former captain.  His apologies
surprised even the stolid policeman.

"Don't apologize for doing your duty, my man," remarked Admiral
Trefusis.  "Hope you're fit.  Must have a yarn with you when I've more
time.  Come along, Ross."

Having seen Mr. Hyde and Ross safely to the outside of the door of Room
445, the Admiral abruptly took his departure.

In reply to a knock the door was opened by a very tired-looking clerk,
who was bravely bearing up under the strain of having to work ninety
hours a week, including Sundays.  Having explained his business, Mr.
Hyde was shown into the presence of an official whose talent was little
short of miraculous.

A dozen precise and pointed questions put him in full possession of all
the facts bearing upon the document that he required.  He touched an
electric bell.  An assistant hurried to his desk.

"Bring me the papers on the von Ruhle case," he ordered in an undertone.

In less than half an hour the transcription was completed, although the
_Capella's_ officer of the watch had not taken down the actual
commencement of the smoke-signal.  Then, having "pressed" the paper in
order to obtain a duplicate copy, the official placed it in an
envelope, which he secured with an imposing wax seal.

"No mistake about it, the war has bucked the civilian staff at the
Admiralty," observed Mr. Hyde to Ross as they gained the street.  "I
can remember a time when all you had to do was to mention someone's
name, and you had practically a free entry.  Your particular pal could
always contrive to have an hour's yarn with you, and perhaps an
interval for refreshment.  They know what working at high pressure
means now."

Hyde was more cautious on the return journey.  He was well within the
limit that he had set himself.  An hour and forty minutes later, the
car drew up outside the coast-guard station.

"Captain Syllenger presents his compliments, Mr. Hyde, and requests
your company on board," said Sub-lieutenant Barry when the _Capella's_
boat arrived to take off the midshipman.  "Ton my word, you haven't
been long.  We didn't expect you back before six o'clock."

Having received his guest, Captain Syllenger led the way to his cabin,
Barry and Ross being included in the party.  The skipper's face glowed
with satisfaction when he had opened the envelope, for the signal as
decoded was as follows:

"(words missing) closely patrolled.  Unable to provide stores here.
Will attempt removal of (word missing) from Station 123 on Friday
night.  Will signal from Station 125 at 1 a.m. on Saturday if possible.
Transports leaving by Needles Channel at daybreak."

Following this was an explanatory note.

"Station 123 is stated to be in Keyhaven Marshes.  Station 125 one mile
west of white house at Milford-on-Sea."

"Humph!" ejaculated Captain Syllenger.  "It looks as if there's trouble
in store for some gentlemen of marked Teutonic sympathies.  I only hope
we'll have a chance of being off Station 125."




CHAPTER XIX

That Friday Night

Three hours later H.M.S. _Capella_ received the following order by
wireless:--

"Await relief by _Taurus_, then proceed to Rendezvous Y, Portsmouth
Command.  _Capella_ to be temporarily attached to Western Inner Patrol."

The meaning of the message was plain to all on board.  The _Capella_
was to proceed to Rendezvous Y, which according to Admiralty
instructions was off Yarmouth, Isle of Wight, where a flotilla of small
craft was patrolling day and night, as a precautionary measure in the
unlikely event of any hostile craft forcing the formidable defences of
the western entrance to the Solent.

At eight on the following morning the _Taurus_ arrived on the station,
and with the least possible delay the _Capella_ made for the west'ard.

Only one incident marked the run.  A few miles from the Royal Sovereign
Lightship, the _Capella_ sighted a number of submarines running on the
surface.  They were on Particular Service, and although opportunities
for torpedoing a hostile surface craft were very remote, the submarines
were constantly rendering yeoman service by keeping the approaches to
the German North Sea ports under close observation.  On rare occasions,
when a German light-cruiser or destroyer did venture beyond the
protection of the mine-fields and guns of the land-batteries, British
submarines were not backward in seizing their chance of letting loose
"tinfish" against their quarry.

Having arrived off Yarmouth, Captain Syllenger reported himself to the
senior officer.  He came back beaming.  The _Capella_ was to take part
in combined sea and land operations for the capture of the German
agents, who were supplying petrol to one of the submarines, and also
for the capture of the U-boat.

The eventful Friday evening came at last.  The _Capella_, in company
with four first-class torpedo-boats, was to be ready at a signal from
Hurst to make a dash through the North Channel.  A fleet of armed
trawlers from the Poole base was to operate farther out to sea, in
order to cut off the U-boat's retreat should she be lucky enough to
escape the attentions of the _Capella_ and her consorts.

At ten o'clock the east-going tidal stream began to set through the
Needles Channel.  Half an hour later it ran with a velocity exceeding
five knots.  The _Capella_, moving at a rate equal to that of the tide,
kept about half a mile from the Isle of Wight shore, with the white,
occulting light of the Needles just visible to the north of Cliff End
Fort.

It was a perfectly calm night, overcast, but with no wind.  A dull
rumble, rising and falling in volume, could be heard from the direction
of the open sea.

"Breakers on the Shingles--a large bank on the starboard hand of the
Needles Channel," explained Barry in answer to the midshipmen's enquiry.

"Then it means that bad weather is approaching," said Ross, who had had
plenty of opportunities of observing the phenomenon of "ground swells"
on the North Cornish coast.  "If it's like this, the U-boat won't be
able to make direct communication with the shore."

The appearance of Captain Syllenger on the bridge put an end to
conversation.  The officers, by the aid of telescopes and binoculars,
kept the Hampshire shore under close observation.

To the naked eye nothing was visible but a dark bank of trees.  Not a
light was to be seen, although there were several houses in the
vicinity.  The position of Lymington, in time of peace discernible by
reason of a strong blaze of light, could only be determined by the
feeble glow of the high red light marking the course up the river.

"It's nearly midnight," observed the skipper.  "If our friends the
Germans are going to shift their supplies from here to Milford, they'll
have to be pretty sharp.  Seems to me like a case of 'nuthin' doing'."

Hardly were the words out of his mouth, when the silence was broken by
a peremptory hail.  The sound travelled clearly across the water,
although the person shouting must have been a mile and a half away.

Then came the jumbled noise of men's voices, quickly followed by two
rifle-shots.  The voices then died away, and, as far as the listeners
on the _Capella_ could hear, all was quiet.

"That's soon over, whatever it was, sir," remarked Barry.

"Hurst calling up, sir," announced a signalman, as a light blinked
rapidly from the fort guarding the Hampshire side of the narrow
channel.  It was the order to proceed at full speed to the position
previously decided upon.

Although the torpedo-boats were speedy craft, the _Capella_ left them
behind "hands down".  Fortunately there were no search-lights to baffle
her quartermaster, for those of both Hurst and the batteries on the
Isle of Wight shore had been previously switched off.  Since the Needle
Channel was closed to all mercantile shipping, the _Capella_ could, and
did, without risk, extinguish her navigation lights.  Only the
phosphorescent spray from her sharp cutwater marked her position.

Suddenly she ported helm, just in time to avoid a collision with a long
dark shape that proved to be an unterseeboot in the act of diving.  Her
commander had detected the pulsations of the _Capella_ motors, but he
was too late.

Round spun the patrol vessel.  From her quarter, a long length of
something that resembled an exaggerated string of sausages was paid
out.  At the rate that the _Capella_ was circling, it was impossible
for the U-boat to escape from her toils.  Dive to a safe depth she
could not, since the maximum depth was but 5 3/4 fathoms.

The last of the "sausages", to which was attached stout flexible wire,
disappeared beneath the water.  Then a jerk upon the wire announced the
gratifying fact that the fugitive submarine had fouled the string of
sausages, which was in reality a number of gun-cotton charges, primed
and connected to a powerful battery by means of an insulated wire.

Sub-lieutenant Fox, who was standing by the firing-key, needed no
orders.  His fingers pressed the ebonite disc.  A hundred yards astern
of the _Capella_ a column of water was flying high in the air, followed
by a tremendous roar.  For one minute the vessel rocked violently in
the agitated waters, then, circling, she made for the spot under which
the explosion had occurred.  With a splash a mark-buoy was dropped
overboard to indicate the position of the shattered U-boat.  By this
time the torpedo-boats had arrived on the scene.

"A deuce of a commotion on shore, Barry," exclaimed the skipper.

"I should be surprised if there were not, sir," replied the Sub.  "The
racket was enough to smash every window within a couple of miles of the
beach.  They're signalling, sir."

"German submarine's boat rowing off.  Intercept her," was the signal
spelt out by the long and short flashes.

"More work," remarked Barry.  "It's like looking for a needle in a
bottle of hay.  Shall I order the searchlight to be run, sir?"

"Very good," replied Captain Syllenger.  "But before you do so you
might signal to Hurst, and request that all available search-light be
brought to bear in this direction."

Soon the hitherto pitch-dark sea was flooded in a blaze of light.
Giant beams from the Isle of Wight shore joined with those of Hurst
Castle to sweep slowly across the waves, supplementing the twin rays
projected from the two search-lights on the _Capella's_ bridge.

It was indeed a brilliant spectacle.  The _Capella_ and the
torpedo-boats seemed outlined in silver.  Along the shore as far as
Hengistbury Head, the low line of cliffs was thrown into strong relief
against the dark background of sky.  The crest of every wave seemed as
if made of delicate filigree work.  Nothing afloat could hope to escape
detection within the radius of action of the concentrated millions of
candle-power search-lights.

Less than a mile away, and about the same distance from shore, a small
black object bobbed buoyantly upon the waves.  It was the ill-fated
U-boat's canvas dinghy, apparently empty.

Down bore the _Capella_, her search-lights fixed upon the object of her
search.  The boat was not deserted.  Lying at full length on the bottom
boards were two men, who had adopted that position, in the vain hope of
escaping detection.

As the patrol vessel approached, they sat up and raised dolorous cries
of "Mercy, Englishmen!"

"Chuck it, Fritz!" shouted one of the British seamen.  "You won't get
hurt.  You ain't in a strafed submarine now, you know."

"Silence!" ordered the skipper.  "Stand by there.  Get that boat
aboard.  See they don't sling anything overboard."

There was precious little that the German seamen could throw overboard,
for when the canvas boat was placed on the Capellus deck it was found
to contain only a pair of oars and two crutches.  What the German
sailors hoped to do had they escaped detection was a matter for
conjecture, for without a compass, food, and water, and in a frail
cockle-shell with every indication of bad weather approaching, certain
death stared them in the face.

Finding themselves well treated, the Germans grew quite communicative.
They freely admitted that they expected to obtain a considerable
quantity of petrol from their agents ashore.  They did not know their
names, or if they did they professed complete ignorance on the point.
Their craft, numbered for some vague reason U7, was built at Altona,
and completed only a fortnight previously.  In addition to her normal
crew of twenty-eight officers and men, she carried five officers and
ten men for instructional purposes.  She was one of four that had come
round Cape Wrath and the West and South coasts of Ireland, rather than
risk the hazardous passage through the Straits of Dover, or the almost
equally dangerous North Channel between Scotland and Ireland.  Two of
the five were missing; the other was supposed to be in the
neighbourhood of Cape Ushant.  U7's particular mission was to intercept
transports that were known to be leaving Southampton for the French
coast.

The men admitted that they had been tricked.  A light had been flashed
seaward, and although the signal was not strictly in accordance with
the prearranged plan, it was sufficiently accurate to delude the U7's
Lieutenant-Commander.

The German officer had shown considerable skill and audacity in closing
with the shore so close to the numerous and powerful batteries.  He
dwelt upon the almost absolute certainty of the gunners devoting their
attention solely to the Needles Channel, and since it was a little past
the time of dead low water the intervening Shingles Bank, which in
places rears itself 20 feet above the sea, would afford an efficient
screen from the search-lights.

But he had reckoned without the patrol vessels.  Barely had the
U-boat's collapsible rowed a hundred yards from her parent when the
_Capella_ raced up, and promptly put another hostile submarine to her
credit.

Early next morning, the _Capella_ having returned to her station off
Yarmouth to await orders, Vernon Haye went ashore in charge of the
whaler in order to pick up mails and secure fresh provisions.

Arriving alongside the little stone quay, he left a boat-keeper in
charge and proceeded towards the post office, while the coxswain and
the rest of the men went in search of the much-desired commodities in
the shape of fresh butter and milk.

Just as Vernon was about to enter the post office, he nearly collided
with a very sleepy-looking subaltern in the uniform of the Royal
Garrison Artillery.

"By Jove, Barraclough!" he exclaimed.  "I didn't expect to see you
here."

Barraclough was an Upper Sixth man at the same school as Haye, but had
left four terms previously.  On the outbreak of war he had applied for,
and had obtained, a commission, and had been stationed, somewhat to his
disappointment, at Hurst Castle.  Beyond a few false alarms and a
liberal experience in target practice, his existence at that isolated
fortress bordered on the monotonous.  He was simply on thorns to be
able to proceed to the Front; the probability was that he would have to
"do his bit" for his country at a spot within 20 miles of his home
until the termination of the war.

"Bless my soul, Haye!" he rejoined.  "Whoever would have thought to see
you here, and in naval get-up.  How long have you been in the Service,
and what ship are you on?"

"Only a few weeks; and I'm on the _Capella_ with Trefusis."

"Trefusis, eh?  Well, he's a lucky boy to have an Admiral for a father.
And the _Capella_?  Then you were in last night's affair?  I heard they
bagged the submarine."

"Rather!" declared Vernon proudly.

Barraclough stifled a prodigious yawn.

"Jolly glad to hear it.  'Scuse me, but I'm beastly tired.  Had a night
of it after those spies across yonder.  Didn't turn in till three, and
at six I had to cross from Hurst to Vic.--that's Fort Victoria, you
know--on duty."

"Did you collar them?" asked the midshipman eagerly.

The subaltern yawned again.

"No," he drawled.  "Worse luck, we didn't; but we had some fun.  You
know we were warned to watch Keyhaven marshes--and a dreary spot it is.
Worse than the most dismal flats on the Essex coast, which is saying a
lot.  Well, before I tell you what happened, I ought to describe the
place.  It's a marsh, with patches of dry ground thickly covered with
furze, that extends from Keyhaven to Lymington River--about four miles.
It is separated from the sea--or rather mud-flats, covered at high
tide--by a low bank on which is an apology for a footpath.

"Our orders were to post a squad at a certain point where the spies
were supposed to have hidden a quantity of petrol.  The place in
question was close to a rifle-butt.  Men were detailed to guard all
roads leading to the marsh, and to allow all traffic, whether
motor-cars, carts, or pedestrians, to pass unchallenged.  The sentries
were on no account to show themselves, except to hold up everything and
everyone coming _from_ the marsh.

"Other men were told off to watch the three available roads between
Keyhaven and Milford, where the submarine was expected to send ashore
for her stores, so you see the U-boat didn't stand much chance of
getting what she wanted.  She copped something she didn't expect.

"As soon as it was dark, my squad left Hurst by motor-boat and landed
near the toll-house at Keyhaven.  It was almost dead low water, you
know, or we might have been able to save ourselves a long tramp--you
couldn't call it a march.

"We followed the wretched footpath, slipping on the slimy mud, and
either tumbling over each other or else side-slipping into the morass,
which was a jolly sight worse.  To make a long story short, we took up
our position, which was in the middle of a circular clump of furze
within 50 yards of the butts, at ten o'clock.

"There we stuck for nearly two mortal hours, and not so much as a
chance of having a cigarette.  Of course the men were frightfully keen,
and it took me all my time to stop them from chin-wagging.  Some of
them began to get jumpy, swearing they saw all manner of men and things.

"I had just looked at my watch--luminous face, thank goodness--when my
sergeant whispered to me that someone was approaching.  It was then
close on twelve.  He was right.  There were three men ambling
cautiously along the sea-wall.  They were talking softly.  Once one of
them stopped, bent under the lee of a furze bush and lit a cigarette,
which seemed a rummy thing for a spy to do unless it was a prearranged
signal.

"We let them come on until they got within 20 yards, then up popped my
sergeant.

"'Halt, who goes there?' he shouted, loud enough to be heard a couple
of miles away.

"Bless me if the three fellows hadn't the cheek to answer in exactly
the same words, although they didn't sound particularly cheerful over
the job; and, instead of halting, one of them came on, holding a stick
above his head.  The others didn't seem very keen to follow him, but
began jabbering away as hard as they could.

"So I gave orders for a couple of shots to be fired over their heads,
just to let them know what to expect when they deliberately ignore a
challenge.  But instead of 'hands up' they bolted, with our men after
them.

"Then I had good reason to bless that blessed marsh, for between us and
the rifle-butt was a deep ditch filled with water, and a nice wire
fence on the other side.  Half a dozen of us, myself included, were
floundering up to our waists; the others were lucky enough to avoid the
ditch by making straight for the path.  But we had the fellows all
right."

"The spies?" asked Vernon.

Barraclough yawned, and then laughed mirthlessly.

"Nuthin' doing," he replied.  "They were three members of a local
defence corps engaged in patrolling the marshes.  Goodness only knows
what for, for they hadn't any weapon with them except walking-sticks.
Perhaps 'twas as well, though, for they might have let rip in their
excitement.  When a man's nerves are all upset it's not safe for him to
have his finger on the trigger of a rifle, you know."

"But the spies?" asked Vernon.

"Not a sign of 'em," replied the subaltern.  "If they were anywhere
about, they must have sheered off pretty quickly when they heard the
racket.  An hour later an orderly brought us word to return to the
fort, so we guessed that something had taken place between a
patrol-ship and the submarine.  But I must be on the move.  Regards to
Trefusis.  If you've a chance to get ashore on the other side, look me
up."




CHAPTER XX

To the Rescue

Twelve hours later found H.M.S. _Capella_ back on her station off
Beachy Head.

The long-threatened gale had burst with great violence upon the South
coast.  Long crested breakers surged towards the chalky cliffs,
thundering with terrific force against the sheer face of the rocks.

Seaward, as far as the eye could reach, was nothing but a confused
tumble of foam, backed by a lowering bank of ragged and sombre clouds.

The _Capella_ and her consorts had to "stick it".  Without orders they
dare not seek shelter in Newhaven harbour.  All they could do was to
forge slowly ahead, keeping bows on to the furious seas.  In spite of
her shallow draught, the _Capella_ was an excellent sea boat, although
inclined to be "jumpy".  Frequently green waves broke over the fo'c'sle
and surged aft as far as the deck-house under the bridge; but with
unfailing regularity the stanch vessel would shake herself clear of the
tons of water that had invaded her deck, to be ready to receive the
next contribution from the hand of King Neptune.

Nevertheless, while the gale lasted it was a time of discomfort.  One
thing for which the crew were thankful was the fact that it was still
September, and the gale was not one of those wintry varieties which are
so trying to the hardy patrollers of the North Sea.

Everything had to be battened down.  'Tween-decks the air was stifling,
and reeked of fumes from the motors.  It was impossible for a man to
stand unsupported.  Anything that had not been securely lashed would be
sure to be flung across the deck by the erratic motion.  No hot meals
were obtainable.  Officers and crew had to eat as best they might,
without the use of articles of civilization such as plates and similar
things.

Ross and Vernon saw very little of each other during the gale, except
for a brief interval during the changes of the watch on deck.  Each
enjoyed his "trick" on deck, as he crouched behind the bulging
storm-dodgers and faced the howling wind and the stinging spray.  It
was greatly to be preferred to being below, cooped up in an atmosphere
which resembled that of an underground scullery on washing-day, with
the odours of petrol and lubricating oil thrown in as extras.

"One thing we've to be thankful for," remarked Barry, "and that is that
it's a sou'wester.  It minimizes the chance of being blown up by a
derelict mine."

"How is that?" asked Ross.

"A sou'easter's the brute for that.  Brings with it dozens of German
mines that have broken adrift from the Belgian coast.  When I was
stationed at Great Yarmouth we had the same game in easterly gales.  It
was nothing unusual to find twenty of the brutes lying ashore; and on
several occasions they have exploded on coming into contact with the
rocks, and then, especially at night, everyone thought that the Germans
had at last ventured to risk 'The Day'.

"I remember one that came ashore a few miles from Lowestoft.  It was a
whopper, of a different type from the rest.  An Engineer officer
brought a dozen young subalterns down to see it and give them an
object-lesson.  He talked for the best part of an hour, explaining its
construction, and laying particular stress upon the need of the
greatest caution when handling it.  Finally he proceeded to explode it
electrically.  The circuit of the battery was tested and found to be in
perfect order, and the wires were then connected with the detonator of
the mine, after the tube containing the fulminate of mercury had been
removed.

"The whole crowd took cover.  The circuit was completed, but the mine
didn't budge.  They tried three times, and finally came to the
conclusion that the thing was a dud.

"Then a squad of soldiers took pot-shots at it until it was fairly
riddled with bullet holes, but still the blessed thing wouldn't
explode.  Eventually it was decided to remove the mine to a laboratory
for examination, and a team of mules was requisitioned to drag it off
the beach.

"One of the mules suddenly took it into his head to be a little bit
premature, for he lashed out, broke away from the traces, and pelted
down the beach.  When the brute came to the place where the mine lay,
he found that the tackle which the men had already rove to shift it was
in his way.  Possibly the sight of a rope upset him, for he backed and
lashed out with his hind legs--and up went the mine with a terrific
bang.  They never found any of the pieces of the mule."

At length, as is invariably the case, the gale blew itself out, and,
although the sea still ran high, the absence of broken water made it
possible for the hatchways to be kept open.

The behaviour of the _Capella_ and her consorts was a matter for
congratulation.  They had stood the test remarkably well, and had
proved themselves good all-weather craft, provided that they could be
kept head to wind.

A week later the _Capella_ returned to Southampton to replenish her
stores, and after three days in port she received orders to proceed to
the French coast and patrol off Cape Levi, where the presence of a
hostile submarine had been reported.

This intelligence was serious.  It meant that, once again, an
unterseeboot had made its way into the English Channel, and was lying
on the track of the British transports and hospital ships running
between Southampton and Rouen.

It took the _Capella_ two hours only to run from The Nab to within
sight of the French coast.  Even then her motors were not running at
the maximum number of revolutions.  Extreme speed was only resorted to
when actually engaged in submarine hunting.

As the vessel closed with the grey cliffs of Normandy, Ross suddenly
shouted: "Submarine on the port bow!"

Less than two cables' length away could be discerned the twin
periscopes and a portion of the conning-tower.  The submarine was not
forging ahead; it was simply stationary, except for a slight movement
caused by the action of the waves.  It certainly was not a British
craft.  It might be French.  The odds were that it was German, since
submarines belonging to the allied nations were not in the habit of
keeping awash, unless in the presence of an enemy.

Quickly the guns, which were already cleared for action, were trained
upon the visible part of the submarine; but as she made no attempt to
move, Captain Syllenger refrained from giving the order to open fire.

Thrice the _Capella_ circled round the mysterious craft, at the same
time gradually closing, since she had nothing to fear from the
discharge of a torpedo.

"I believe she's abandoned, sir," said Barry.

The _Capella_ stopped.  Preparations were being made for the lowering
of a boat, when one of the seamen shouted:

"It's a dud, sir; a blessed decoy-bird!"

The man was right.  Upon investigation, the submarine was found to be
nothing more than a couple of barrels covered with painted canvas.  Two
thick poles passing vertically through them, and weighted at the
lowermost ends to give the necessary stability, served as periscopes.

"There's a real submarine knocking about, I'll swear," said the
skipper.  "Put a shot into those barrels, Morgan."

One shell was sufficient.  Little more than a hundred chips floating on
the surface was left of the decoy.

The _Capella_ was about to resume her course when a warning cry was
heard:

"Torpedo coming, sir!"

From a point bearing half a mile on the vessel's port quarter, the
track of the on-coming torpedo was clearly discernible.  The _Capella_,
being without way, would undoubtedly have fallen a victim had it not
been for her light draught, for before she could forge ahead the
missile passed under her keel.  Its track could be followed as far as
the eye could reach, which showed that it was a modern weapon propelled
with superheated air and having a range of about five miles.

Straight for the source of the missile, tore the British craft, but her
effort to grapple with the unterseeboot was in vain.  The submarine had
dived immediately.  No sounds betrayed her presence in the vicinity.
Had the U-boat been moving, the churning of her propellers would have
been distinctly audible.

"She's got away, worse luck," growled Sub-lieutenant Fox.  "I wonder
how she did it?  It's too deep for her to sound, and she can't be
moving under her own power."

"We'll have her right enough," rejoined Barry, the optimist.  "A light
haze and a calm sea is what we want.  We'll run her down in less than a
week, you mark my words."

Four days passed.  The _Capella_ kept her station almost without
incident.  Ship after ship, deeply laden with troops and munitions,
entered the sand-banked estuary of the Seine, having been escorted thus
far by destroyers.  Ship after ship, more lightly burdened, left the
river, homeward bound.  Amongst them were hospital ships, clearly
distinguishable by their broad green bands and conspicuous red crosses
on both bows and quarters.  A big action had taken place "somewhere in
France", and the passing of the Red Cross vessels was the aftermath of
a dearly-bought victory.

Yet nothing occurred to threaten the constant stream of shipping.  It
seemed reasonable to surmise that either the U-boat had met with an
accident or else that she had transferred her energies to another area.

Meanwhile Ross and Vernon had been working hard, improving their
seamanship.  Under the instruction of the two sub-lieutenants they were
making rapid progress in navigation; they could fix their position by
the use of a sextant, were able to use the semaphore, and, generally,
competent to carry out the duties required as midshipmen of the watch.

Captain Syllenger had long before overcome his prejudices against the
sons of Flag Officers--at least in their case--and even expressed his
willingness to grant them each a certificate of proficiency, should
they wish to transfer to one of the cruisers of the Royal Navy.

At length the _Capella_ received orders for recall to her station off
Beachy Head.  She was to put into Havre to revictual that day, leaving
at 9 a.m. on the morrow.

The lads were heartily glad when the _Capella_ left the malodorous
_bassin a flotte_.  The irksomeness of lying in the harbour at Le Havre
palled upon them, even after a few hours.  They yearned for the open
sea almost from the time their ship made fast alongside the grimy quay.

Forty minutes after leaving French waters, the _Capella_ sighted a
large cargo-boat steaming northwards.  She was high in ballast and
rolling like a barrel.  On bringing glasses to bear upon her, the
_Capella's_ officers found that she was the _Orontabella_, one of the
vessels chartered by the British Government and fitted as a
horse-transport ship.  She was doing 16 knots to the _Capella's_ 34,
and when first sighted was nearly five miles off.

Suddenly a low rumble was heard by the crew of the patrol-vessel.
Telescopes and binoculars that had just been laid aside were again
brought into action, and it was seen that the transport was sinking
rapidly by the stern.  She had been torpedoed under the starboard
quarter.  The terrific impact of the explosion had torn a large hole,
besides shattering the rudder and one of the propellers, while all her
boats in davits were rendered useless by the concussion.

It was a matter of but a few moments before she made her final plunge.
Already signals were fluttering from her stumpy masts--the well-known
N.C. (in distress; want immediate assistance) and A.R. (boats are stove
in).

Captain Syllenger gave a quick glance astern.  There were other
vessels, but low down on the horizon.  To expect succour from them was
for the present out of the question.  He had a double task: to attempt
to destroy the aggressor, and to rescue the transport's crew.

"Prepare to lower boats!" he shouted.  "A midshipman and a couple of
hands in each.  Guns' crews stand by!"

Clang, chang, went the engine-room telegraph.  Like a greyhound, the
_Capella_ increased her speed, until she was within a quarter of a mile
of the foundering vessel.  Then reversing engines, she almost lost way
at less than a cable's length from the transport.

By this time Ross and Vernon were in their respective boats.  Before
way was off the ship the falls were paid out and the disengaging gear
cast off.

"Give way, men," ordered Ross.

His scanty crew, for more men could not well be spared, "gave way" with
a will, gaining a couple of lengths before his chum was able to push
off.

With hardly a pause the _Capella_ dashed off, quickly increasing her
pace to full speed ahead, in her quest for the U-boat that had launched
the deadly torpedo.

The _Orontabella's_ stern was now under water.  She had a pronounced
list to starboard.  Dense volumes of smoke and steam, pouring from her
funnels and hatchways, showed that the water had already invaded her
boiler-room.  Above the hiss of the scalding vapour and the rush of
escaping air, could be heard the terrified neighing of a dozen or more
wounded horses, for whom no escape was possible.

Clustering on the fo'c'sle were about twenty or thirty men, the
officers and crew who had survived the explosion; for the death-roll,
especially in the engine-room and stokehold, was very high, men being
overwhelmed by the inrush of water before they could scramble up the
steep ladder and through the narrow hatchway.

The waiting men showed no signs of panic.  Those who could swim had not
troubled to don their cork life-belts, but were calmly engaged in
lashing their life-saving devices round the shoulders of their less
fortunate comrades.

[Illustration: THE SINKING OF THE "ORONTABELLA" (missing from book)]

Ross ordered his men to back towards the foundering vessel.  He
realized that at any moment the transport might plunge suddenly, and
the danger of being dragged down by the suction was a thing he had to
avoid.  There was also a risk of the boat being swamped by the men as
they clambered on board.

"Jump!" he shouted.  "Not too many at a time."

Three men accepted the invitation: two good swimmers and a non-swimmer.
The former, grasping their struggling companion by the shoulders,
struck out without much difficulty and reached Ross's boat, where they
were quickly hauled into safety.

Setting the rescued men to take an oar each, for there were several to
spare lying on the thwarts, Ross took the whaler closer in, since he
had now more means of propulsion at his command.

Four more followed, and were picked up by Vernon's men.  Meanwhile the
bows of the _Orontabella_ were rising high out of the water, as the
stern sank correspondingly deeper, until those of the officers and crew
who still remained on board had to cling desperately to the rails to
prevent themselves slipping into the maelstrom that surged over the
submerged part of the sinking ship.

Suddenly the vessel dived.  Where a few seconds previously a towering
mass of black and red plating rose high above the boats, there hung a
cloud of smoke, steam, and spray, while all around the water was
thrashed white with foam.

"Give way, men!" shouted Ross.

The rowers were too late.  Before the boat could pull clear of the
scene of disaster, a vicious, crested wave, so hollow that the lean
quarters of the whaler were unable to rise to it, poured into the frail
craft.

The next instant Ross and his crew were struggling in the confusion of
the broiling sea.

Vernon, although farther from the spot, narrowly escaped the fate of
his chum.  It was surprising what a terrific commotion the
_Orontabella_ caused at the last.  For some minutes he could see
nothing beyond the tips of the blades of the oars.  Everything else was
enveloped in smoke, steam, and spray.

Gradually the waves subsided and the wind dispersed the pall of vapour.
The sea was dotted with the heads of swimmers.  Ross's boat, with her
stem and stern-posts just visible above the surface, was waterlogged,
yet retained sufficient buoyancy to support half a dozen men.

Here, indeed, was a pretty pickle.  At the very most, Vernon's boat
would hold fifteen or sixteen men.  The _Capella_ was almost out of
sight.  The whole attention of her officers and crew would be centred
upon the U-boat.  So long as there was any indication of the latter's
whereabouts, the patrol-vessel would cling tenaciously to her quest.

There was very little left floating from the sunken ship.  A few
gratings, handspikes, a couple of breakers, and fragments of the
shattered boats, but nothing substantial enough to support a man above
water; and in mid-Channel, although it was only September, the sea was
too cold to enable the swimmers to keep afloat very long without almost
certain danger of cramp.

Vernon looked around for his chum.  He saw him sharing an oar with one
of the crew.

"Come on, my lads!" shouted Ross encouragingly.  "We'll hike her up.
Half a dozen of you who have life-belts come round this side, and when
I say 'All together!' lift for all you're worth."

The men obeyed as quickly as they could in the circumstances.  Finding
that they could easily keep afloat, the non-swimmers had regained their
confidence.  Piloted by those who could swim, the men ranged themselves
along one gunwale of the waterlogged whaler.

"All ready?" asked Ross, whose knowledge of how to empty a waterlogged
Canadian canoe prompted him to try a large, heavy boat.  "Together!"

Up rose the boat's gunwale as high as the men's arms could reach, but
with a dull swish the whaler resumed its former position.  In lifting
one side the other had dropped deeply beneath the surface, and the
attempt to shake out the water had ended in failure.

"Now then," ordered Vernon, taking his turn to direct operations.  "All
swimmers get overboard for a few minutes.  Those with life-belts get on
board, and take off your belts."

In five minutes a dozen cork life-belts were available.  Manoeuvring
his boat alongside the waterlogged whaler, Vernon gave directions for
the belts to be lashed underneath the thwarts, so that they were
completely submerged.  Then taking the whaler's painter he hove taut
until, added to the lifting powers of the cork and the upward strain on
the ropes, the gunwale rose a good three inches above the water.

This done, one of the _Capella's_ men, armed with a baler, began
throwing out the water from the whaler.  In another five minutes the
boat showed sufficient buoyancy to allow two more hands to clamber on
board.  They, too, baled vigorously, with the result that once more the
whaler was free from water.

Between the two boats, all the survivors of the _Orontabella_ were
easily accommodated; but when at length the midshipmen looked for the
_Capella_, the patrol-boat was nowhere to be seen.




CHAPTER XXI

Adrift in the Channel

"She'll be back for us soon," declared Vernon optimistically,
addressing his chum, for the two boats were within twenty feet of each
other.  "Can you see any signs of her now?"

Ross stood upright in the stern-sheets and, shading his eyes with his
hand, gave a careful look in the direction where the _Capella_ was
supposed to be.

"No," he answered.  "And I cannot see any signs of the other vessels we
saw some time ago.  We'd better let the men rest on their oars."

Unknown to the two midshipmen, they had for the last hour and a half
been in the grip of the strong west-going tide that surges along the
French coast.  In that interval they had been carried out of the course
of the vessels they had sighted, and were some four or six miles from
the spot where the _Orontabella_ had sunk.

Another hour passed.  The men who had been in the water took the
opportunity of drying their clothing in the hot sunshine.  They treated
their misfortune lightly, making very little reference to the loss of
their vessel.  One would have thought that being torpedoed was almost
an everyday occurrence.

As the minutes slipped by, it began to occur to Ross and his chum that
the _Capella_ had missed them entirely.  In another few hours night
would be coming on, and the prospect of spending ten hours of darkness
in a couple of open boats in mid-Channel was not at all alluring.

Each boat was equipped with compass, lead-line, signal-book, lamp, box
of biscuits, and beaker of water.  None of these articles belonging to
Ross's boat had suffered, in spite of their being immersed, except the
lamp, for the provisions were in watertight boxes.  Masts and sails
were not in the boats, having been left on board the _Capella_ when the
rescuers put off hurriedly on their errand of mercy.

"What's the best thing to be done, skipper?" asked Ross, addressing the
master of the _Orontabella_.

"Well, sir, since you ask me," was the reply, "I'd shape a course due
north.  We'd be in the track of craft making up and down Channel before
it gets dark.  If we don't fall in with any vessel, we can carry on.
'Taint so very far to land, considering the number of hands we've got
in the boats."

Quickly the available oars were manned, the men being told off in
relays to row for half an hour at a time, while the skipper of the
torpedoed boat relieved Ross at the yoke-lines.  The mate, who had been
picked up by the other boat, was also able to give Vernon a spell.

At six o'clock, a biscuit and a small quantity of water were served out
to each man, and preparations were made for the approaching night.
Vernon's boat, which possessed the only lantern that would burn, was to
take the lead as soon as darkness set in, the light enabling the whaler
to keep in touch with her consort.

"Jolly funny where the _Capella's_ got to," remarked Ross to the
skipper.  "With her speed she could search a couple of hundred square
miles by this time."

"'Spose she wasn't torpedoed?" asked the _Orontabella's_ master.

"No jolly fear!" replied the midshipman decidedly.  "She's
torpedo-proof.  We've had plenty of them fired at us, but never the
least danger of being hit."

"It's a good thing the sea's calm," continued the skipper.  "We're
doing a good four knots.  Twelve hours at the very most ought to bring
us in sight of the Wight, but we've dropped a long way to lee'ard.
P'raps it's as well, for it's no joke to be in the thick of the
cross-Channel traffic at night, with only a tuppenny dip to light us.
Good heavens!  What's that?"

Less than fifty yards from the boat a pole-like object, throwing off a
double feather of spray, was forging through the water.

"A periscope, sir!" shouted half a dozen voices.

Ross did not require to be told that.  With considerable misgivings, he
saw the metal shaft rise higher and higher out of the water; then the
tip of an ensign-staff, followed almost simultaneously by the snout and
conning-tower of a large German submarine.  Finally the unterseeboot
rose to the surface, revealing her entire length, which was not less
than three hundred feet.

She slowed down.  The aperture in her conning-tower opened and a couple
of officers appeared.  From hatchways fore and aft, seamen clad in grey
fearnought coats came tumbling on deck, greeting the British with jibes
and laughter.

"So you getting on, Englishmen!" exclaimed a leutnant.  "Still it is
long vay to land, hein?  An' where vos der _Capella_?  Suppose I tell
you: we her haf sent to der bottom.  Goot night, ver' goot night.  Our
ver' kind regards to Jellicoe."

The U-boat forged ahead, then, getting way, made off at high speed.  In
a quarter of an hour she was out of sight.

"I suppose those fellows were telling the truth, old man," called out
Ross, addressing his chum.

"'Fraid so," replied Vernon.  "They had her name pat, so it looks as if
the poor old ship's done for.  But, I say, what a whopper of a
submarine!"

"One of the new type, I should fancy," said the skipper of the
_Orontabella_.  "I shouldn't be surprised if she were a mine-layer as
well."

Darkness fell upon the scene.  The men rowed doggedly, Vernon setting
the course by the simple expedient of keeping the Pole Star in line
with the boat's stem.  It saved the strain of peering into the compass
bowl, and in any case the boats were bound to hit the English coast,
unless they were swamped or run down.

Throughout the long night the steady progress was maintained.  It was
horribly cold.  Most of the men were lightly clad in imperfectly dried
garments.  Both Ross and Vernon were glad when the officers of the
_Orontabella_ relieved them, since they could take turn at the oars and
derive a certain amount of warmth from the exertion.

Day dawned at last, a brilliant pink sky that betokened bad weather
before the day was out.  Away on the starboard bow could be discerned a
grey cliff surmounted by dark hills.  It was the Isle of Wight, distant
about six miles off.

With the appearance of the sun the wind freshened, and soon developed
into a strong breeze dead in their teeth.  Spray began to fly over the
bows, soon to be followed by green seas, that necessitated constant
baling.  It was quite evident that every yard of that six miles meant
desperate work, with the chances of being swamped before the boat
reached land.

The men, weakened by hunger and exposure, stuck gamely to their task,
yet after another half an hour's hard pulling the boats seemed no
nearer their object.  They were barely holding their own against the
wind and waves.

"What's to be done now?" asked Ross, consulting the experienced
skipper.  Although the midshipman was in charge, he was not above
asking the advice of a man who had been to sea almost as many years as
the lad had been days.  "We're hardly making headway, and the sea's
beating up fast."

"And the men are almost done up," added the skipper.  "It's bound to be
worse before it gets better.  I would suggest that we ride to a
sea-anchor, and trust to luck to be picked up."

The men quickly got to work.  A triangle was composed of six oars in
pairs lashed together, two of the boat's gratings being secured between
the ash spars.  To the apex the anchor was made fast, in order to make
the sea-anchor float in a vertical position, its weight compensated by
the use of the now empty water-beaker as a float.

Secured by three spans of equal length, which in turn were bent to the
boat's painter, the sea-anchor was dropped overboard.  For some
distance the whaler drifted to leeward, until held by the strain of the
painter she rode head to wind, and in comparative safety in the wake of
the floating breakwater.

Vernon's boat then came close alongside.  Her painter was caught and
secured, allowing her to ride astern.

The crews were then at liberty to rest, with the knowledge that their
drift was little more than half a knot.  Yet every two hours they would
be drifting a mile farther from shore, unless their plight were
observed by passing vessels.

By this time the sea was running high.  At one moment the whaler would
be tossing high upon the rounded crest of a wave, with the other boat
deep in the trough.  At the next, nothing was to be seen from the
whaler save an incline of green water and a canopy of dark-grey sky.
On either side the crests were white with foam, yet, thanks to the
sea-anchor, hardly a drop of water was taken in over the boats'
gunwales.

The men sat in silence, turning their backs to the keen wind.  A few
who had tobacco smoked.  Those who had not were glad to chew the small
quantity given them by their more fortunate comrades.  As for Ross and
Vernon, they were glad to doze, lying on the damp bottom-boards with
their heads pillowed on their arms.

Ross was almost asleep when he was aroused by one of the men announcing
that a vessel was in sight.  At the prospect of rescue, all hands were
alert.  The man was right, for, as the whaler rose on the crests of the
waves, a dark, grey shape could be discerned through the mirk at a
distance of about a couple of miles.

Quickly the shape resolved itself into a large four-funnelled cruiser
pelting down-Channel at full speed.  Unless she altered her course she
would pass within a hundred yards of the boats.

"Lash a shirt to the boat-hook, lads!" ordered Ross.

A few moments of intense anxiety followed.  Then a groan of
disappointment rose from the men as the cruiser ported helm.

She was then a couple of miles to windward.  The smoke from her funnels
drifted around the boats, making it impossible for the derelict men to
see what she was doing, until the evil-smelling haze dispersed, showing
the cruiser less than two cables' length away and bearing down towards
them.

From her after bridge a seaman was semaphoring vigorously.

"Will slow down to windward of you," read the message.

"Oars, lads!" ordered Ross.

The bowman of each boat promptly cut the painter.  With renewed spirit
the rowers bent to their work, and soon the boats were alongside and
under the lee of H.M.S. _Oxford_, armoured cruiser of the County class.

By the aid of bowlines the rescued men were quickly hauled over the
side.  Without delay the _Capella's_ boats were cut adrift, and the
cruiser proceeded on her way.




CHAPTER XXII

An Unexpected Capture

"I can see no possibility of landing you at present," said the officer
of the watch, after Ross had reported the events that had led up to the
rescue of the two boats.  "We're under sealed orders.  We have to make
for a certain rendezvous at full speed.  When we arrive we shall know
where we are bound for--until then we are quite in the dark.  We'll
wireless, however, and let the Commander-in-Chief at Portsmouth know
that you are safe."

"Have you any news of the _Capella_?"

"Yes; she was mined while in pursuit of a submarine.  It is a dickens
of a puzzle to know why, for our sweepers were over there early that
morning and never found a single mine.  Whatever it was, it was not so
powerful as they generally are, for the _Capella_ was able to make for
shore and run aground within a few miles of Barfleur.  All hands were
saved, luckily, but I'm afraid this gale will do for her entirely.
It's blowing great guns."

"Then those fellows on the unterseeboot were wrong," remarked Vernon.
"They said she had gone down with all hands.  We believe that the
submarine is a mine-layer, and perhaps it was one of her mines that the
old _Capella_ bumped against."

"Let's hope the patrol-vessels will settle her," rejoined the officer
of the watch.  "But you must be awfully knocked up.  I'll introduce you
to your new messmates, and they'll give you a shake-down in the
steerage flat.  The _Orontabella's_ officers can mess with the
'warrants', and the men will be berthed for'ard."

The Lieutenant stepped to the top of the ladder from the navigation
bridge.  A couple of midshipmen were standing on the superstructure,
watching with professional interest the splicing of a six-inch hawser.

"Mr. Sefton!" sang out the officer of the watch.

The midshipman ran up the ladder and saluted.

"Your messmates for the time being," continued the Lieutenant, after he
had formally introduced Trefusis and Haye.  "They've had a pretty rough
time, and they are jolly peckish, I know."

Midshipman Sefton led the two chums below, and piloted them into a very
long room on the main deck.  It was plainly, nay scantily furnished,
and appeared at first sight to be utterly cheerless.  Possibly the idea
was heightened by the fact that frequently the scuttles were obscured
by the seas that slapped viciously against the cruiser's sides.

"This is the gun-room," explained Sefton apologetically.  "We've had to
clear it out pretty thoroughly, you know.  No knick-knacks or
pretty-pretties in war time.  Sorry the other fellows aren't here.
We're four one-stripers, three midshipmen R.N., and five midshipmen
R.N.R.--a jolly lively crowd of us, I can assure you."

He touched a bell.  A messman appeared.

"Jones," ordered the midshipman, "a good square meal for two, and jolly
well look sharp about it."

"You've got to be dead nuts on that chap if you want anything done in a
hurry," explained Sefton after the man had cleared off.  "It's the only
way to check slackness.  No doubt he gets his own back by giving us
plum-duff without troubling to extract the cockroaches; but we manage
to thrive on it.  By the by, I'll tell my servant to sling a couple of
hammocks for you.  There'll be no need to turn out before dinner."

Sefton hastened below to acquaint the marine who, for the sum of ten
shillings a month, acted as the budding Nelson's factotum to make the
necessary preparations for his new chums.  By the time he returned, a
substantial lunch had been set before Trefusis and Haye.

"I say, you fellows," remarked the midshipman; "I notice that
Eccles--that's the officer of the watch, you know--was greasing his jaw
tackle a good bit.  Did he mention where we are bound for?"

"Nothing definite," replied Vernon.  "He said that the ship was under
sealed orders."

"Then it's no use hazarding a guess," decided Sefton.  "It might be
anywhere from China to Peru.  In any case, it's a change from what
we've been doing--knocking about in the North Sea, waiting for an
appointment which the Germans flatly decline to keep.  Four months
solid, and I've never seen a gun discharged except at target practice."

During the progress of the meal young Sefton was a little inclined to
patronize his guests.  Perhaps he did it unconsciously.

"My governor's a post-captain," he observed in the course of
conversation.  "What's yours?"

"Only an Admiral," replied Ross.

"Is he, by Jove!" exclaimed Sefton.  "Then why the deuce are you a
'with but after'?"

"A what?" asked Trefusis, somewhat mystified.

"An R.N.R. man ranks with, but after, an R.N. fellow with equal rank,"
explained the midshipman.  "It's a fact: look it up in the King's
Regulations.  But, I say, do you play footer?  We're in a match.
Gun-room versus Ward-room, coming off this week.  If you play, I'll get
Cranbury--he's president of our mess--to put you in the team."

The meal over, Ross and Vernon were taken to the steerage flat, an
electrically lighted space out of which opened the cabin of the junior
officers.  At the after end of the flat, a marine sentry paced day and
night, his post extending from the stern torpedo-tube to the gun-room
door on the port side, and to the armoured door on the starboard side.
Amongst his varied and multitudinous duties, particularly strict orders
were given him not to allow anyone to put their hands on the
paintwork--one of the standing orders dating from the prehistoric days
before the war, when "spit and polish" were regarded as being
absolutely essential to the efficiency of H.M. ships.

At three bells in the second dog-watch, the _Oxford_ having arrived at
the rendezvous, the sealed orders were opened.  It was then found that,
in company with the _Guildford_ and the _Launceston_, the cruiser had
to proceed to Halifax, Nova Scotia, to escort a contingent of Canadian
troops to Liverpool.

This was but one of the manifold odd jobs performed by the British Navy
in connection with the war--necessary, but without any prospect of
excitement.  The trip was regarded as a picnic, after weeks of
monotonous patrol duty, for when 800 miles west of Ireland there was
little likelihood of falling in with any hostile submarine, while other
German craft had been swept off the board months previously.

On the third day out the football match came off.  Ross and Vernon were
included in the gun-room team, and never before had they participated
in a rugger match in such strange circumstances.  The _Oxford_ was
pitching slightly in the long Atlantic swell.  The "ground" was the
port side of the quarter-deck, nets being rigged up to prevent the ball
getting very much in touch with the sea.  The fun was fast and furious,
the referee being inclined to tolerance; and before half-time half the
players were off the field owing to minor injuries, ranging from the
smashing of the Assistant Paymaster's eyeglasses to the laying out of
the portly Engineer-Commander.

Suddenly the _Oxford_ turned 8 degrees to starboard.  The alteration of
course resulted in a break in the game.  Something out of the usual had
occurred for the cruiser, which was the leading vessel in line ahead,
to break out of station.

A bugle sharply sounded the "G"--officers' call.  For'ard the bosn's
mates' pipes were turning up the hands.  The Captain, Commander, and
officer of the watch were on the fore-bridge looking steadily at a dark
cloud of smoke showing beyond the horizon.

It was a ship on fire.  The alert officer of the watch had noticed the
smoke, which was much too dense to be caused by the vessel's furnaces.
On reporting the matter to the captain, the latter immediately ordered
the _Oxford_ to be steered in that direction.  As senior officer, he
gave orders for the other cruisers to stand on that course.

"She's quite a small packet, I should imagine," remarked one of the
Subs.  "At any rate she's not fitted with wireless."

In half an hour the cruiser was sufficiently near to see clearly the
distressed vessel.  She was a cargo-boat of about two thousand tons.
Amidships, flames were mounting fiercely from her hatches.  She had
stopped her engines, and was preparing to lower boats.  Aft, she flew
the Stars and Stripes, upside down as a signal of distress.

The ship was doomed.  Fanned by the light breeze, the flames were
rapidly spreading.  Her cargo undoubtedly consisted of highly
inflammable material, since it blazed freely, while the smoke smelt
strongly of burnt oil.

The _Oxford_ stopped at four cables' length to windward of the burning
ship.  She could do nothing beyond rescuing the crew on board.  There
was no necessity to lower her boats, since the cargo-boat obviously had
enough for all hands.

At length the boats of the unfortunate ship were lowered.  There was no
undue haste.  Men deliberately threw their bundles into the arms of
their waiting comrades before they swarmed down the falls.  The captain
was the last to leave, a bulge under his coat betraying the fact that
he had taken the ship's papers with him.

"Nothing of an explosive nature in her cargo," said Ross to his chum.
"Otherwise they would have sheered off a bit quicker.  My word, how she
does burn!  Isn't it a grand sight?"

"Yes," admitted Vernon.  "It's lucky there's help at hand.  Knocking
about in the boats in mid-Atlantic must be ten times as bad as in the
English Channel."

"I beg to differ," remarked one of the Subs who was standing by.
"There's not so much shipping, I'll admit, but the waves are longer and
more regular in mid-ocean.  It's marvellous what an open boat can do
when she's put to it, except in very broken water."

The boats were now approaching the _Oxford_.  A monkey-ladder had been
lowered to enable the men to surmount the lofty side of the cruiser,
while the sailors, always ready to lend a hand in cases of distress,
were swarming down to the net-shelves in readiness to receive the
personal belongings of the American seamen.

"Look!" whispered Vernon.  "Isn't that chap like our old pal
Ramblethorne?"

He pointed to a tall, bronzed man clad in canvas jumper and trousers,
and wearing a grey slouched hat.  He was sitting in the stern-sheets of
the second boat, with his shoulders hunched and his face half-averted.

"Like him?" echoed Ross.  "By Jove, it's he, right enough!"

Trefusis was right.  Von Hauptwald, alias Ramblethorne, had succeeded
in evading the hue and cry after his escape on Harley Bank, and had
continued to remain hidden in the house of a naturalized German in
Cheshire until the search for him had somewhat relaxed.

He then managed to ship as a fireman on board a vessel bound for
Montreal, knowing that his chances of getting out of Great Britain
would be greater if he made for a Dominion port rather than one in the
United States.

At Montreal he promptly deserted, made his way across the border, and
thence to New York.  Here he picked up with a German-American
shipowner, who readily agreed to help him back to Germany.

A cargo-boat, the _Tehuantepec Girl_, was loading with a cargo
consisting of cotton, ready-made clothing, and leather equipment.
Nominally her destination was Leith.  Her manifest and bill of lading
were made out to that effect, but secretly her skipper had instructions
to make for Stockholm.  If he were overhauled and taken into Lerwick by
a British patrol-boat, well and good.  The owners must be compensated
by the British Government, even if the _Tehuantepec Girl_ was miles out
of her course for Leith.  On the other hand, if the boat succeeded in
reaching the Baltic, she would be conveniently "captured", by previous
arrangement, by a German cruiser or destroyer and taken into Kiel.

Unfortunately the fact of keeping secret the real destination of the
_Tehuantepec Girl_ led to her undoing.  A German dock-hand, who was
really in the pay of the Teutonic Government, had placed an infernal
machine in the cargo, setting it to explode two days after leaving New
York.

In less than a quarter of an hour after the discovery of the outbreak,
the fire had taken such a firm hold that all attempts to subdue it were
hopeless.

And now von Hauptwald, in the disguise of a Yankee deck-hand, was being
rowed towards a craft which he would have given almost anything to
avoid--a British cruiser.

Still, he was not dismayed.  The chances of detection were absurdly
small.  None of the _Tehuantepec Girl's_ crew knew his true personality
except the captain, and he was to be handsomely rewarded as soon as the
spy was safe in German territory.  On the other hand, there might be
one amongst the 655 forming the complement of the _Oxford_ who might
recognize the one-time doctor who had lived at Devonport.

"Let's get out of his way," suggested Vernon.  "We'll inform the
Commander, and he will order him to be put under arrest."

"I'm not going to budge," declared Ross.  "If he sees us, what can he
do?"

"I'm not afraid of him," protested Haye.

"Very well, then; let's stop where we are.  He's got to know sooner or
later."

The first boat had already delivered her human cargo Upon the cruiser's
quarter-deck.  As each man's name was taken down by the master-at-arms
he was sent forward.  The first mate remained in conversation with the
Commander until the arrival of the _Tehuantepec Girl's_ skipper.

Von Hauptwald was one of the last men to come aboard.  As he swung
himself over the rail he gave a swift glance at the group of officers.
His eye caught that of Ross Trefusis.

For a moment the spy thought that he was mistaken, but a second glimpse
confirmed his suspicions.

"Steady on there!" shouted the Commander.  "What the deuce are you up
to?"

Von Hauptwald had broken into a run across the quarter-deck.  With a
bound he cleared the stanchion-rails, and plunged head foremost into
the sea.

He had realized that to remain on the cruiser meant arrest and ultimate
death as a dangerous spy.  Better by far to be drowned without further
delay than to experience all the horrors of lying under sentence of
death.

He had acted spontaneously, yet there was method in his madness.  By
running across to the other side of the ship there was little chance of
the boats being able to pick him up ere he sank for the last time.  Not
until he rose to the surface did he realize his difficulty.  He was a
strong swimmer, and the natural instinct to strike out overpowered his
determination to sink.

There was a rush of officers and men to the ship's side to see what was
taking place.  With two exceptions, they thought that the supposed
seaman had suddenly lost his reason.

Two seamen, one a brawny specimen, the other a red-haired
middle-weight, dived after the would-be suicide.  Others were on the
point of following when the Commander restrained them.

"Away sea-boat!" was the order.

The _Oxford_ was now forging slowly through the water.  During the
rescue of the _Tehuantepec Girl's_ people, she had drifted rather too
close to the burning ship to be safe, should an explosion occur.
Already von Hauptwald was fifty yards astern, with the two seamen
swimming towards him with powerful strokes.

His efforts to drown were a failure.  He simply couldn't keep his head
under.  His attempts to swallow quantities of salt water only increased
the instinctive motion of the limbs to keep himself afloat.  Bitterly
he regretted that he had not picked up some heavy metal object during
his career across the cruiser's quarterdeck.

The approach of his would-be rescuers made him realize the necessity of
self-destruction.  At the encouraging shout of "Cheer up, old mate,
you're safe!" spluttered by the leading seaman, he dived, pressing his
chest with both hands in the hope that he would be able to expel the
air from his lungs.

A horny hand gripped him by the arm.  He felt himself being drawn to
the surface.  As his head appeared, he swung round and dealt the seaman
a powerful blow with his fist.  The man, taken completely by surprise,
relaxed his grip.  Von Hauptwald's blow had almost broken his shoulder.

"Be careful, Ginger!" he shouted to his mate.  "He's fair balmy.  Mind
he don't plug you."

The second seaman swam in a circle just beyond reach of the spy's arm.
His attempt to get behind the German failed, for the simple reason that
von Hauptwald gave no opportunity for an attack in the rear.  The other
sailor, floating on his back and rubbing his injured arm, was content
to shout advice and await developments.

The red-haired man was not deficient in courage, but he did not at all
relish the idea of tackling single-handed a powerfully built
maniac--for such he took the spy to be.  He wisely awaited the approach
of the _Oxford's_ sea-boat, which, manned by four rowers who were
encouraged by Midshipman Setley, was being urged rapidly towards the
scene.

"Way enough!" shouted the middy.

The bowman boated his oar and leant over the bows.  As he did so von
Hauptwald avoided his grip, and, seizing the boat's keel, brought his
head in violent contact with the elm planking.

Then it was that Ginger saw his chance and took it.  Grabbing the
German by the legs, he hung on like grim death, shouting to his
comrades to "tackle the lubber".

Within an ace of capsizing the boat, von Hauptwald was hauled on board.
He fought desperately.  For a moment it seemed as if he would more than
hold his own against the four seamen, until one of them, seizing a
stretcher, dealt the spy a crack on the head that laid him senseless
across the thwarts.

"Couldn't help it, sir," exclaimed the man apologetically.

"You did perfectly right, Dickenson," said the midshipman.  "He's
properly mad.  Come on, you men, are you going to bathe for the rest of
the day?"

The victim of von Hauptwald's attack had to be assisted into the boat,
which, on making the ship, was quickly hoisted and secured.

Meanwhile the _Tehuantepec Girl_ was on the point of sinking.  From
stem to stern she was a roaring furnace.  Mingled with the roar of the
flames could be heard the hiss of water coming in contact with the
red-hot plates, while ever and anon came the crash of metal as the deck
beams gave way and fell into the hold.

Suddenly she parted amidships.  The flames died out, overpowered by the
inrush of water.  A thick column of smoke and steam arose as the bow
and stem [Transcriber's note: stern?] portions floated apart.  Then
with the roar of escaping air the remains of the Yankee cargo-boat
disappeared, to find a resting-place 7000 fathoms deep on the bed of
the Atlantic.




CHAPTER XXIII

Mined

"So that accounts for the fellow's behaviour," remarked the Captain of
the _Oxford_, after Ross and Vernon had communicated their discovery to
the Commander, who in turn reported the news to the skipper.  "The
doctor says he is out of danger, eh?  From a medical point of view, no
doubt.  Put him in the cells, Master-at-arms.  We'll take good care not
to land him at Halifax."

Upon arriving at the Nova Scotian port, whither the _Oxford's_ consorts
had preceded her, the officers and crew of the _Tehuantepec Girl_ were
landed.  Forty-eight hours elapsed before the transports were ready to
leave, and thus Ross and Vernon, with most of the officers of the
cruisers, had an opportunity of a "spell ashore".

On the homeward run nothing untoward occurred, except that, instead of
proceeding to Liverpool, the cruisers and their convoy were suddenly
ordered by wireless to make for the Clyde.

Off the Pladda Light the transports were met by a flotilla of
destroyers, while the cruisers were ordered to proceed via Cape Wrath
to rejoin the fleet at Rosyth.  Without slackening speed the three
cruisers flung about, and steered a course immediately opposed to the
one they had previously been following.  Experience had told them that
speed was one of the essentials to safety, even when in land-locked
waters such as the Firth of Clyde.

"You don't look like leaving us in a hurry," remarked Midshipman
Sefton, when he communicated the latest change of plans to Trefusis and
his chum.

"We don't mind in the slightest," Ross hastened to assure him.  "It's
jolly comfortable on board the _Oxford_."

"Wait until we're ordered straight away for patrol work," said Sefton.
"It's more than likely that we may be pushed off to the Norwegian coast
without having so much as a sniff at Rosyth.  We'll just about hit the
equinoctial gales, and in those latitudes they get ice and snow pretty
early in the autumn.  But, by the by, I heard the doctor tell the
Commander that your pal, von Hauptwald, is in a pretty state of funk."

"I shouldn't wonder," replied Ross.  "A court-martial will make it
pretty hot for him."

"It's hardly that," said Sefton.  "The fellow's absolutely crazy with
fear.  He's been imploring the master-at-arms and the sentry on the
cells to ask the skipper to shift him above the water-line.  It's only
since the ship arrived in home waters, so it seems as if he's in mortal
dread of being cooped up below and the _Oxford_ being mined or
torpedoed."

"And what did the Captain say?"

"Merely told the M.A.A. to carry on.  Since the cells are below the
water-line, and the King's Regulations say that prisoners are to be
placed in cells, that ends the matter."

Passing through the Little Minch, and continually steering an erratic
course in order to baffle any unterseebooten, should they be operating
off the West coast of Scotland, the _Oxford_ rounded Cape Wrath.

In spite of a rapidly falling glass the weather still remained fine,
although the heavy swell encountered off the coast of Sutherland and
Caithness betokened, in conjunction with the barometer, a gale at no
distant date.

"This will be you fellows' last night on board," remarked Farnworth,
one of the Acting Sub-lieutenants, as Ross and Vernon prepared to turn
into their hammocks after a strenuous sing-song in the gun-room mess.
"We'll be at Rosyth before noon to-morrow.  'Fraid it's been a bit tame
after the _Capella_.  Beyond that affair of the _Tehuantepec Girl_
there hasn't been much doing.  The small fry get all the excitement,
I'm sorry to say.  These armoured cruisers seem to be neither fish,
fowl, nor good red herring in these times."

It seemed to Ross that he had been asleep only a few minutes when he
was suddenly awakened by a terrific crash, followed by a concussion
that shook the cruiser from stem to stern.  His hammock rolled so
violently that he promptly fell out on the floor of the flat.  Before
he could rise, the occupant of the next hammock tried his level best to
thrust his toes into Trefusis' mouth.  The rest of the midshipmen, who
were watch below, were either thrown from their hammocks or had leapt
hurriedly from them.  The electric lights were out.  The shock had
either shattered the carbon threads or had broken the wires.

"Torpedoed!" exclaimed a junior midshipman.

"Dry up!" ordered Sefton sternly.  "On deck all of you; there's the
'Action' bugle--no, it's 'Collision Stations'."

Just then a light appeared.  The sentry in the steerage flat had lit
one of the bulkhead lamps, which are always in readiness for use in the
event of a break-down in the electric current.

The cruiser was listing perceptibly to starboard.

She was in danger of turning turtle and foundering, but even in the
face of death not one of the handful of young officers showed the
faintest sign of fear.  If in their inmost minds the lads were a little
timorous, they bravely kept their feelings to themselves.  They were
part and parcel of a British warship's complement.  They had a
reputation to maintain--the reputation of a Navy dating back for
centuries.  It was in safe keeping, for the _Oxford's_ midshipmen were
made of the right stuff.

A few made a hasty dive into their sea-chests to make sure of some
precious article.  Others scrambled into their thick coats, bantering
each other as they did so.

Overhead, the noise of hundreds of feet could be heard as the men
doubled aft to the quarter-deck.  Above the tumult rose the shrill
pipes of the bos'n's mates' whistles, and the hoarse shouts of "On
deck, every mother's son of you!" bawled by a leather-lunged petty
officer.

"We don't want to leave you, but we fear that we must go," parodied one
of the midshipmen, giving a farewell glimpse into the gun-room that had
been his home for the last fifteen months.  "Come on, you fellows,
who's going to enter for the long-distance swimming race?"

Up the ladder swept the throng of youthful humanity, followed by the
sentry, who had received orders to abandon his post.  On the half-deck,
the gun-room officers met the swarm of senior officers issuing from
their cabins, mostly clad in pyjamas and uniform caps.  The
Gunnery-lieutenant was afterwards heard to declare solemnly that he had
seen the Paymaster issuing from the ship's office with the ledger on
his head, while under his left arm he held his cap.

"Let's stick together, old man!" exclaimed Ross as the chums gained the
quarter-deck.

The first hurried rush aft had now given place to strict discipline.
The men were falling in as calmly as if mustered for divisions.  Some
were blowing up their pneumatic swimming-collars, others helping to
adjust a comrade's life-belt.  A few were joking and talking, none of
the officers gainsaying them.  By virtue of an unwritten law the men
were allowed to smoke, and the odour of strong tobacco wafted across
the broad quarterdeck.

"Got a fag, Lofty?" Vernon overheard a burly stoker ask his neighbour.

"No; I don't smoke, mate," replied the man.

"You will soon," replied the stoker, and a roar of merriment rose from
the lips of the men within hearing.  They thought the retort was a
smart bit of humour, and, when at length the implied nature of the
man's words dawned upon him, even Vernon had to smile.

From the after bridge, search-lights were playing upon the waves.  The
light quick-firers were manned ready to deal with any visible foe.  On
the navigation bridge the Captain, with the officer of the watch, was
pacing calmly up and down the slightly inclined structure.

Presently he was joined by two dark forms--the Commander and the
carpenter.  A bugle sounded the "Still".  A hush fell upon the swarm of
humanity, the silence being broken only by the hiss of escaping steam,
and the rush of water under the action of the powerful Downton pumps.

"My lads!" shouted the skipper.  "The old ship is holding out.  We'll
get her into dock yet.  Pipe down!"

The _Oxford_ had not been struck by a torpedo.  Examination showed that
she had bumped against a mine, with the result that the fore
compartments were flooded.  Fortunately the transverse bulkhead and
watertight doors withstood the strain of the terrific inrush of water.
Although well down by the bows the cruiser was in no immediate danger.

The watch below disappeared from sight; those of the officers who were
not on duty retired to their cabins, yet few of them slept again that
night.

As Ross and his chum were about to leave the quarterdeck, the Commander
strode by.


"Pass the word for the master-at-arms," he ordered.  "Master-at-arms
went below, sir, to release the prisoners," reported a petty officer.

"By Jove!" whispered Ross.  "I'd clean forgotten Ramblethorne.  I
wonder how he liked the business?"

"Let's wait," suggested Vernon.

They took up their position on the leeward side of the after 7.5-inch
gun-shield.  Here they were sheltered from the wind and out of sight of
the alert Commander, although they could hear what was being said.

"Master-at-arms is in the sick-bay, sir," reported the messenger as he
came up at the double.  "He's nearly done for, trying to get to the
prisoners.  The ship's corporal managed to release the two ordinary
seamen, but the spy's done in, sir--I mean he's drownded."

Almost immediately following the explosion, the master-at-arms had
hurried to the cells.  The flat was in darkness.  The sentry on No. 6
post, in charge of the prisoners, was lying stunned on the floor of the
passage.  Water was surging aft.  Already it was up to the knees of the
master-at-arms as he plunged through the gloom towards his goal.

The three prisoners were shouting in mad panic.  They realized their
awful peril.  Caged like rats in a trap, they felt certain that the
cruiser was foundering, and that they would be carried down in a living
tomb until the pressure of water burst open the comparatively strong
steel walls of the cell.

At length the chief of the ship's police forced the door of the
nearmost cell.  By sheer good luck he inserted the key into the lock
without having to fumble for the opening.  The prisoner, a young seaman
who had broken out of the ship at Halifax, was too terrified to know
his way to safety.  He clutched at the master-at-arms, following him to
the next cell.

The water was now waist-deep.  In trying to find the keyhole the
master-at-arms dropped the keys.  It took some minutes to find them--a
loss of valuable time.

The noise of the inrushing water was deafening.  For all the petty
officer knew, the ship might be about to make her last plunge.  Yet his
duty lay before him.  At the risk of his life the prisoners must be set
free.

A light appeared upon the scene.  A ship's corporal, bearing a lantern,
descended to the flat with the laudable intention, of assisting his
superior.

The door of the second cell flew open, but a rush of water on the
flood, under the movement of the stricken vessel surged and swept the
master-at-arms off his feet.  His forehead came in violent contact with
the steel frame of the door, and, rendered senseless, he dropped
inertly upon the flooded floor of the passage.

"Pull yourselves together, men!" exclaimed the corporal to the two
prisoners.  "You're all right.  Bear a hand here."

Together they carried the unconscious master-at-arms out of the flat.
The corporal returned to liberate the occupier of the third cell--von
Hauptwald.  But once again the keys were missing, having slipped from
the insensible man's hand.

The water in the confined space was now shoulder-deep.  The corporal
could hear the stout bulkhead groaning under the pressure.  Fixing the
lantern on a bracket he dived, groping with both hands for the keys.
At length he found them, and threw open the door of the cell.

"Out you come!" he shouted.

There was no reply.  Von Hauptwald had ceased to shout for some
minutes.  The silence was ominous.

A movement of the badly stricken ship sent the water well over the
corporal's head.  He was swept off his feet.  It was time for him to
get back to safety.  He had done all he could.  The spy was dead.




CHAPTER XXIV

"Shrap"

It was late in the afternoon when the _Oxford_ arrived, under her own
steam, at Rosyth.  Although the dry docks were in use, accommodation
was quickly found for the damaged cruiser by the simple expedient of
floating out a battleship that was being cleaned and recoated with
anti-fouling composition.  Since speed is an absolute necessity for
efficiency in war-time, it was the practice to dock all the ships of
the battle-cruiser and armoured cruiser class in rotation, the margin
of safety being sufficient to allow this to be done without impairing
the strength of the squadrons.

By the aid of powerful arc-lamps the dockyard hands took the crippled
_Oxford_ into dock, and, the caisson having been replaced, the water
was quickly pumped out.  The damage done was found, on examination, to
be limited to a space extending 30 feet from the bows.  The actual
aperture caused by the explosion measured 6 feet by 30 inches, but the
adjacent plates had been buckled and the bolts "started" under the
violent concussion.  Well it was that the armoured bulkhead had
withstood the strain, otherwise nothing could have saved the ship.

There was no delay in setting to work.  Almost before the last of the
water had been pumped out of the dock, stagings were built up round the
bows, and scores of shipwrights set to work to rebuild the damaged
portion of the hull.  Under normal conditions the work would have taken
a couple of months, but, by working day and night, the efficient
dockyard staff hoped to effect repairs within nine days.

Since the commencement of the greatest war the world has ever yet seen,
it was the custom to allow the officers and crews of torpedoed or mined
ships--if they were fortunate enough to be numbered amongst the
survivors--seven days' leave.  A rest on shore was necessary for the
crews to recover from the mental shock, for it was found that although
the men might escape from physical injury and appear bright and
cheerful immediately after the occurrence, the reaction was most marked
at about forty-eight hours afterwards.

Ross and Vernon, although not borne in the books of the _Oxford_,
received permission to go on leave.  Since Haye's father was somewhere
in the North Sea, and he had no near relatives, he gladly accepted
Ross's offer to sample again the hospitality of Killigwent Hall.

It was late when their train arrived at King's Cross; so much so that
the lads realized it would be useless to attempt to catch the Cornwall
express that would land them at St. Bedal just before midnight.

"I vote we have an evening in town," suggested Vernon.  "Let's go to a
theatre.  It seems ages since I was inside a music hall, or even a
picture palace."

"All right," agreed Ross.  "We'll have a jolly good square meal before
we go.  I know of a decent little hotel just off the Strand."

The two midshipmen took the Underground as far as Charing Cross.  As
they emerged from the station they renewed their acquaintance with the
metropolis in war-time.  The streets were plunged in almost Stygian
darkness.  Omnibuses and taxicabs crawled painfully through the gloom;
pedestrians were cannoning into each other at every step.  The only
relief to the blackness were the two search-lights from the Admiralty
Arch that swung like gigantic pendulums across the dark and misty sky.

"Let's get out of it," exclaimed Ross, as he just managed to save
himself from being run down by a motor-car.  "It's a jolly sight more
dangerous than keeping the middle watch on the old _Capella_."

Five minutes later they were sitting down to an ample dinner, provided
at a cost that proved pretty conclusively the futility of the German
submarine blockade.  In the well-lighted room there was little to
suggest that business was not proceeding "as usual", except perhaps the
predominance of khaki-clad officers.

A string band was discoursing the latest operatic music, the diners
were laughing and chattering.  Within, the gaiety and light-heartedness
contrasted violently with the dismal gloom inflicted upon the
metropolis as a result of precautions adopted by the triple authorities
responsible for its defence against air-craft.

Presently the band finished one item on the programme.  The comparative
silence that followed was almost immediately interrupted by a series of
sharp reports, punctuated by a deeper crash.

"Zepps!" exclaimed a dozen voices.

Instantly there was a rush--not for the deep cellars underneath the
building, but for the open street.  The white faces of a few of the
guests showed that they had, perhaps, a little anxiety, but for the
most part an excitable curiosity took possession of the crowd.

"Come on!" exclaimed Ross to his chum.  "Let's see the fun.  We haven't
had a chance of seeing a real Zepp before."

The lad's words voiced the thoughts of nine-tenths of the dwellers of
the metropolis who were within sight of the would-be Terror of the Air.
Useless, indeed, were the official warnings as to the right thing to be
done when the Zeppelins came.  One man, however, drew a respirator from
a hand-bag and proceeded to don it, until a roar of laughter from the
stream of people issuing from the hotel caused him somewhat
shamefacedly to replace the useless article.

Into the street the lads elbowed their way.  The progress through the
long corridor of the hotel reminded them of a football scrum.  It was
not the blind rush of panic; merely a desire to lose nothing of the
"fun".

A couple of thousand feet overhead, a silvery-grey, bluff-pointed
cylinder was moving with apparent slowness.  Half a dozen search-lights
concentrated their beams upon it.  All around were rings of smoke,
marking the bursting shells from the anti-aircraft guns; yet,
apparently untouched by the hail of bullets, the giant gas-bag passed
on, hurling out death and destruction upon the greatest city on
earth--a city that, until the present war, had only once heard the
thunder of hostile guns.

Breathlessly the lads watched the progress of the huge Zeppelin,
momentarily expecting it to collapse and come tumbling, a tangled mass
of flaming wreckage, to the ground.  Viewed from below, it seemed
impossible for the airship to escape the bursting shells.  The air was
rent by the crash of falling bombs and the sharp reports of the
"anti's", while in the distance could be heard the clatter of broken
glass.  The explosive bombs wrought havoc upon the homes of harmless
Londoners.  Flames, too, were springing up, throwing a lurid glare upon
the sky.

Yet, unless actually within radius of the German explosives, the
populace was remarkably calm.  Men, women, and children watched the
Zeppelin, much in the same way as if they were witnessing a Brock's
display at the Crystal Palace.  Once again German frightfulness had
failed--and failed badly--to attain its desired end.

"Hurrah!  She's got it properly in the neck," shouted an excited
special constable, as the Zeppelin gave a sudden lurch and began to
drop at an acute angle.

But the next instant the silvery envelope was hidden in a cloud of
dense black smoke.  Seconds passed, but no shattered wreckage streamed
earthwards.  When the vapour dispersed, the Zeppelin was nowhere to be
seen.  Under cover of the smoke-cloud she had dropped a large quantity
of ballast, and had soared skyward to a great altitude.

Gradually, like the rumble of a passing thunderstorm, the reports of
the distant anti-aircraft guns died away.  The Zepps had taken
themselves off, leaving half a dozen fires and hundreds of more or less
damaged buildings to impress upon the strafed English that insularity
is no longer a protection from the cowardly night-raiders of the air.

"The show's over," declared Ross.  "I vote we turn in.  By Jove,
there'll be a rush to the recruiting offices to-morrow!"

Requesting to be called at eight, the two midshipmen entered the lift
and were whisked up to their room.

"What's that noise?" asked Vernon, pausing in the midst of unpacking
his portmanteau.

"Something in the corridor," replied Ross.

"I don't think so.  It's something or someone under my bed.  Lock the
door, old man; no, don't ring, if it's a burglar we'll tackle him."

Haye knelt by the bedside, Ross standing behind him ready to grapple
with the intruder.  Cautiously Vernon lifted the valance.  As he did so
he quickly withdrew his hand, which had come in contact with something
warm and moist.

"Dash it all!" he exclaimed.  "It's a dog.  Come out, sir!"

He was right.  The animal gave a low whine, but made no attempt to
budge.

"Mind the brute doesn't fix you," cautioned Ross.

"No fear," replied his chum confidently.  "All dogs take to me.  Come
along, old boy."

Again he groped with his hand.  His fingers touched the long, silky
hair on the animal's neck.  Slowly he drew the creature from its place
of concealment.  It was a sheep-dog pup, of about four months.

"Pretty-looking dog," exclaimed Vernon.  "I wonder how it came here?
Suppose it was frightened at the racket.  It looks terrified out of its
wits.  Good dog!"

The pup fixed its large brown eyes upon Vernon's face, and attempted to
wag its stumpy tail.  As it did so the lads discovered that its hind
quarters were tinged with blood.

"Oh, you poor little beggar!" said Vernon sympathetically.  "However
did you get that?  I say, Ross, fill that basin with water."

"Better send for the boots," suggested Trefusis.  "He'll take it to a
vet.'s, or perhaps he'll know whose dog it is."

"Not much chance of finding a vet. at this time of night," objected
Vernon.  "Even the chemist will be busy with minor casualties.  No, I
won't worry the management.  I've doctored dogs before now."

He began bathing the matted hair.  The flow of blood had ceased, but
upon examining the wound he found that it was a small circular incision.

He felt the spot.  The pup, hitherto patient, uttered a low moan.

"There's something hard there," reported Vernon.  "It's only a little
way under the skin.  We'll have it out.  Hold his head, old man.  Don't
let him yelp; keep your hand over his muzzle.  I'm afraid I must hurt
the poor little beggar a bit."

Using the little blade of a knife, Haye adroitly probed the wound.
Soft-hearted as he was, the action seemed to hurt him more than the
patient; but his efforts were rewarded by the extraction of a small
steel ball.

"A shrapnel bullet!" exclaimed Ross.  "That accounts for the poor
little brute being in such a terrible funk.  Give him a drink of water.
He'll be better now.  We can bandage the wound with our handkerchiefs."

Five minutes later the dumb patient, his hind quarters swathed in
elaborate bandages, was lying contentedly upon the hearth-rug, his
stumpy tail, protruding between the folds of linen, wagging, as he
tried to express his gratitude in doggy fashion.

"Now what's to be done?" enquired Ross.

"Let him stop until morning," replied Vernon decisively.  "There might
be a row if the hotel people know that there's a dog in the bedroom.
The owner can't be much of a chap if he doesn't make enquiries."

"Perhaps he hasn't missed the dog," suggested Ross; "or it's just
likely he isn't stopping at the hotel.  Well, here goes.  I'm turning
in."

Ten minutes later both midshipmen were fast asleep.  They had no middle
watch to keep, and as for Zeppelins, they were merely a passing show.

At daylight Vernon was awakened by something licking his face.  The
pup, having shown his contempt for bandages by biting them to ribbons,
was standing on his hind legs and licking his benefactor's nose, while
his tail was wagging with the rapidity of the flag of an expert
signaller.  The hardy little animal had made light of his wound.

Having dressed, the midshipman made enquiries of the waiter, but
without satisfactory results.  No one in the hotel had a dog.

"I'll report him to the police," decided Vernon.  "Ten to one the owner
won't claim him.  At any rate I'll stick to him.  He's awfully fond of
me already."

After breakfast Vernon sent the obliging waiter to purchase a collar,
for the sheep-dog was wearing none.  Sticking closely to Vernon's
heels, the pup followed his new master to the police station, where an
inspector took down a number of particulars.

"Very good, sir; that's all I want.  I don't fancy you'll hear any more
about it."

"What are you going to call him?" asked Ross, as the chums were seated
in a first-class carriage, with the dog at Vernon's feet, on their way
to Cornwall.

"Zepp," replied Vernon promptly.

"Not patriotic," objected Ross with a laugh.

"I think so," rejoined his chum.

"Why?"

"Because, like last night's Zeppelin, he turned tail when he had a
shrapnel bullet in his stern."

"That's all very well," said Ross, "but you can't explain all that to
everyone.  Why not call him Shrapnel?"

"All right.  'Shrap' for short," agreed Vernon.  "Good boy, Shrap!  Wag
your tail, you little rascal."

And Shrap obeyed promptly.  Evidently the choice of a name reminiscent
of bodily injury troubled him not one jot.




CHAPTER XXV

Off the Belgian Coast

"A chance of seeing something exciting at last!" exclaimed Ross.  "Of
course we've not had altogether a dull time, but this ought to be
absolutely 'it'."

Two months had elapsed since the lads saw a hostile air-ship over
London.  Now they were about to see what a fleet of heavily armed
British ships could do--not against a practically defenceless town, but
against the strongly fortified German batteries on the Belgian coast.

Trefusis and Haye were on board the _Capella_, lying in the outer
harbour at Dover.  It was not the _Capella_ that had come off
second-best in an encounter with a floating mine, but another, similar
in almost every respect to the lost patrol-boat.  She was manned, too,
by the same officers and crew--with one exception.  Sub-lieutenant John
Barry had obtained his promotion, and had been appointed to H.M.S.
_Hunbilker_ in command.

What the _Hunbilker_ was, no one on board the _Capella_ knew.  The
Admiralty publications at their disposal were blank as far as that ship
was concerned.  Speculation ran high: some of the officers expressing
their opinion that Barry's command was a subsidized cargo-boat; others
that she was one of the mosquito flotilla that had been evolved out of
modern naval requirements.  All were wrong, as they had yet to learn
something more of the type of vessel flying the White Ensign that was
helping to sweep the seas of the Black Cross of Germany.

"Well, old boy, how do you think you will like the racket?" asked
Vernon, stooping to pat the massive head of a healthy-looking
sheep-dog.  Shrap had been allowed, by the Captain's permission, to
join the _Capella_ as a mascot--the pet of both officers and crew, and
of Vernon Haye in particular.

Shrap winked knowingly, then trotted off to a secluded part of the
chart-room, where, under a locker, he had hidden the remains of what,
half an hour previously, had been Sub-lieutenant Fox's shaving-brush.

The _Capella_ was by no means the only craft rolling sluggishly in the
vast artificial harbour.  There were seven motor patrol-vessels,
specially detailed for the forthcoming operations as tenders to the
sea-planes.

A strong array of monitors, craft of ugly but utilitarian design,
low-lying, and mounting two 14-inch guns, had assembled for the purpose
of making it hot for the Hun on the morrow.  Only light-draughted craft
were to be employed in the attack, since they could approach within
very effective range of their guns, and at the same time stand little
chance of being torpedoed by a handful of unterseebooten that had been
transported in sections to Zeebrugge and there fitted for service.

According to the Admiral's plan, the monitors were to approach Ostend
just after daybreak.  In the offing a number of empty transports were
to assemble, protected by a powerful flotilla of destroyers.  The
appearance of these transports would be taken by the Germans as an
indication of an attempted landing of a British force, and troops would
be hurriedly massed to repel the threatened invasion.

The monitors were thereupon to fire a certain number of rounds, then,
followed in a parallel course by the transports, make for Zeebrugge.
Alternate visits to both the Belgian ports in German hands were to be
made throughout the day, thereby wearing out the German troops in
fruitless marching and counter-marching, and at the same time diverting
a strong body of men from a section of the trenches upon which the
British troops were to deliver a sudden and unexpected assault.

At four in the morning the monitors began to leave Dover Harbour.
Thanks to the stringent military precautions taken in the
town--precautions that could with decided advantage be imitated
elsewhere--the presence of spies was almost, if not quite, a matter of
impossibility.  Unheralded by the Kaiser's agents, the small yet
powerful vessels cleared the entrance to the breakwater and headed for
the Belgian coast.

An hour later a masthead lamp blinked from the _Vega_--the senior
officer's ship of the patrol flotilla.  Then, in line ahead, the swift
motor craft slipped quietly out of the harbour to overtake their slower
consorts.

The _Capella_, like the rest of her sister ships, was cleared for
action.  Stanchion-rails were unshipped; everything likely to splinter
was sent below.  In the wake of the armoured protection, sandbags were
placed to reinforce the steel plating.  Although the patrol-vessels
were not to take part in the bombardment, they had to be prepared in
case a forlorn hope in the shape of a few German torpedo-boats might
attempt a sudden onslaught.

As attendants upon the sea-planes, too, it was possible that the
patrol-boats would have to approach within range of the garrison
artillery, especially in the event of one of the aerial craft being
disabled and falling into the sea, on its return from "spotting" the
hits of the monitors' guns.

Dawn had not yet broken when the monitors, followed at two miles'
distance by the motor patrol, came in sight of the search-lights on the
low-lying Belgian coast.  Beyond the limit of direct rays, yet within
range of their monster guns, the monitors were safe from detection.
All that was wanting was the presence of the sea-planes, for whose work
daylight was essential.

Slowly a pale light spread on the north-eastern horizon.  The short
wintry day was breaking.  The sea was calm.  The air was piercingly
cold.  A thin coating of frost covered the _Capella's_ deck.  Ross and
his chum were heartily glad of their thick pilot-coats, mufflers, and
woollen "mitts", as they sheltered behind the breast-work erected on
the bridge.

Captain Syllenger slowly paced the bridge, frequently glancing at the
clock in the chart-room, since it was almost a matter of impossibility
to consult his watch, owing to his generous accumulation of clothing.
It was now nearly eight o'clock, but as yet there were no signs of the
expected sea-planes.

Just then the dull morning light was pierced by a brilliant flash from
one of the monitors.  The watchers on the _Capella's_ bridge could see
the low-lying hull give a decided jerk in a sternward direction under
the reaction of the enormous projectile.

Long before the shell reached its objective, other 14-inch guns added
their quota, and the air was rent with the flashes of the ordnance and
the ear-splitting detonations following the discharge.

"By Jove!" exclaimed Sub-lieutenant Fox, who with his brother officers
had had telescopes levelled upon the faintly outlined sand dunes.
"There are the sea-planes!"

He was right.  Flying at a great height the air-squadron had passed
over the warships, and had taken up their observation stations without
being seen or heard by anyone on board the patrol-vessels immediately
over the German batteries, they were cutting "figure eights" and
describing seemingly erratic circles, while the observers, coolly
wirelessing the results of the monitors' shells, hardly heeded the
furious fire directed upon them by the hostile anti-aircraft guns.

On a point extending for nearly three miles, the shore was torn by the
terrific explosive shells.  Clouds of sand, and yellow smoke mingled
marked the scene of destruction, as battery after battery was spotted
and promptly put out of action.  Across the dunes could be seen swarms
of ant-like figures--German troops flying for shelter from the
devastating fire of the British guns.

But the action was by no means a one-sided one.  Guns, large and small,
replied; the heavier ordnance vigorously at first, and then gradually
slackening down as the lyddite shells sought out the fixed
emplacements.  The lighter guns, mounted on armoured motor-cars, gave
more trouble, since, after every shot, each piece was moved a hundred
yards or more.

For several minutes the lads watched the unusual spectacle through the
binoculars.  Then something resembling a concentrated tornado screeched
above their heads.  Instinctively they ducked, the glasses falling from
their hands.  Ten seconds later Ross ventured to look up.  Vernon was
still holding his hands over his face.  Then slowly he, too, opened his
eyes.

The lads smiled sadly at each other, picked up their binoculars, and
somewhat shamefacedly resumed their former positions.

It was their baptism of heavy gun-fire.  A 42-centimetre shell had
ricochetted and leapt full twenty feet above their heads.

Captain Syllenger was standing a few paces from them.  Luckily, thought
Ross, the skipper's back was turned, and he had not noticed the action
of his young subordinates.  But Trefusis was wrong.  The Captain had
seen them.  Out of consideration, for he remembered his own sensations
when first under fire, he affected not to notice the temporary panic
that had overtaken the midshipmen.

The _Capella_ was now running at half speed, in a direction parallel to
the shore.  All around, the sea was torn by the falling projectiles,
most of which were sufficiently large to send her to the bottom like a
stone.  Yet, beyond the wounding of her wireless operator, the loss of
her signalling-mast, and the shattering of one of her boats, she came
off lightly.  Although not the object of the hostile guns, she narrowly
escaped several ricochets, until, at a signal from the senior officer,
the patrol-vessels withdrew to a safer distance.

One of the monitors, too, was slowly steaming seawards, well down by
the bows and smoke issuing from her fo'c'sle, while her single funnel
was riddled like a sieve.

"Sea-plane returning, sir!" announced Sub-lieutenant Fox.

Flying at an altitude of about a thousand feet, one of the aerial
scouts was making towards the line of patrol-vessels.  She was flying
steadily; her motor was purring rhythmically; a trail of thin bluish
smoke from her exhaust belied the suggestion of an overheated engine.
Yet something must have taken place for her to have quitted her
observation station.

Promptly Captain Syllenger gave orders for the _Capella's_ motors to
stop, then "Easy astern" until way was off the ship.

Making a graceful volplane, the sea-plane alighted with a faint splash
upon the surface of the water, and "taxied" to leeward of the
motionless vessel.

The sea-plane was a "two-seater".  The rearmost or observer's seat was
unoccupied.  In the foremost was a young Flight-Sub-lieutenant heavily
clad, and his clean-shaven face almost hidden by an airman's helmet.
For the first time, the officers on the bridge of the _Capella_ noticed
that the light steel plating was holed in many places, while the planes
bore testimony to the accuracy of the enemy's shrapnel.

"A casualty!" sang out the Flying officer.  "My pilot's been hit.  Can
you take him on board?"

Two of the _Capella's_ crew swarmed over the side and gained the
nearmost float, whence they clambered upon the body of the sea-plane.
At the same time, one of the davits from which the _Capella's_
shattered boat had hung was slung outboard.  By dint of careful
manoeuvring, the sea-plane was brought alongside with her main planes
practically parallel to the side of the ship.

The injured man was lying on the floor of the fuselage.  A canvas band
was strapped round his waist, and, supported by the two seamen, he was
gently hoisted on board the ship by means of the davit tackle.

The Flight-Sub swung himself over the side of the _Capella_ and
ascended the bridge.

"Got it hot at fifteen hundred feet," he explained.  "My pilot was
winged.  Hit twice, I believe.  Luckily the old bird kept fairly steady
until I could clamber into the pilot's seat and take control.  Rough
luck, too.  We were just doing a useful bit of spotting.  I suppose,
sir, there's no one on board who can handle a 'plane?"

"I'm afraid not," replied Captain Syllenger.

"Rough luck!" exclaimed the Sub despondently.  Then, brightening up, he
asked:

"Can you lend me a 'wireless' man?  I could take on the pilot's job."

"Our man's knocked out," said the skipper.

"That's done it!" exclaimed the Sub.  "There's a particularly tough
battery that I wanted to see knocked out.  No. 5 was almost on it when
we got it hot."

Ross was thinking rapidly and deeply.  He knew the Morse code well.  He
had dabbled in wireless telegraphy at school.  Perhaps----

He felt that it was almost too impertinent to offer his services, yet
the matter was urgent.  It was dangerous, too, most dangerous; but the
midshipman had learnt to place duty before personal consideration.

"Well?" asked Captain Syllenger as Trefusis stepped up and saluted
smartly.

"I'll go if I can be of any assistance, sir," said Ross.  "I can Morse
and use a buzzer, and I have a knowledge of wireless."

"Carry on, then," replied Captain Syllenger.

"Good man!" exclaimed the Flight-Sub-lieutenant.  "Can you stick
heights?"

"I've done a lot of cliff climbing--I am a Cornishman, you know," said
Trefusis.  "I haven't had a chance of flying before."

"You have now!" added the Flight-Sub.




CHAPTER XXVI

Disabled in Mid-air

Ross climbed agilely into the observer's seat, and, at his flying
companion's suggestion, buckled a broad leather strap round his waist.
At his right hand was the wireless transmitter, together with a pair of
prismatic glasses and map.  The latter was held in a transparent
celluloid case, while the glasses were secured by a cord sufficiently
long to enable the observer to use them in any direction.  Everything
was attached to the sea-plane so that in the event of the machine
having to "loop the loop" nothing would be lost.

The Sub, who for the present was to act as pilot, took his place in the
forward part of the body.  Giving a few preliminary touches to the
mechanism, he announced that everything was in order.

The self-starter was released and the motor fired, causing the twin
propellers to buzz smoothly and powerfully.

Ross waved his hand to his chum as the sea-plane glided away from the
_Capella_, and from that moment his whole attention was centred upon
the work on which he was engaged.

For nearly a hundred yards the sea-plane "taxied", rising lightly over
the waves; then almost imperceptibly it glided upwards with an even
motion.  Ross could hardly believe he was flying until he saw the sea
apparently receding from him.

"All right?" asked the Sub through the telephone that formed the only
audible means of communication between pilot and observer.  "Not
feeling giddy?"

"Not a bit," replied Ross.  Without experiencing the faintest sensation
of vertigo, he found himself able to lean over the side of the chassis
and look down at the scene two thousand feet beneath him.

The sea-plane was rising in a direction diverging obliquely with the
coast.  She was, in fact, almost over the line of empty transports that
looked little bigger than a fleet of toy boats.  Farther away could be
discerned the _Capella_ and her consorts, moving with apparent slowness
upon a perfectly calm sea, for at that altitude the waves were merged
into a flat surface.  Small splashes of white--the spray thrown up by
falling shells--could be seen all around the patrol-vessels, which, in
obedience to a signal, had now taken up a position rather nearer to the
monitors.

Presently the Flight-Sub, having gained the desired altitude, moved the
steering-plane ever so slightly.  Quickly the machine answered her
helm, swinging round until she pointed towards the land.

Three minutes later Ross found himself immediately above the British
monitors.  The sea-plane was now pitching slightly in the disturbed
air, for the concussion of the heavy weapons was distinctly felt even
at seven hundred yards above the bombarding ships.  Although the roar
of the concerted cannonade was deafening, Ross heard not a sound of it.
To all intents, as far as he was concerned, the guns might have been
fired with silencers attached to their muzzles.  The whirr of the
sea-plane's motor and the rush of air past his ears out-voiced every
other sound.

Five miles beyond the line of monitors, could be discerned the Belgian
coast, composed for the most part of undulating sand-dunes dotted with
clusters of buildings.

As the sea-plane approached the land Ross could, with the aid of his
binoculars, distinguish other objects--wavy lines, dotted with ant-like
figures bunched together round something that looked like stumps of a
lead pencil.  The lines were the German trenches, the "ants"
grey-coated artillerymen, and the "stumps" the heavy howitzers.

"That's our pigeon!" spoke the Flight-Sub through the telephone.  "The
battery a hundred yards to the north of that ruined church tower.  Our
fellows haven't knocked it out yet.  Wireless them; fifty yards over."

Ross sent the desired information.  The sea-plane, having flown over
its objective, turned, describing an elongated figure eight.  As she
swung round, Ross noticed a mushroom-like cloud of white smoke a short
distance beneath, and to the left of the fuselage.  Then another a
hundred feet immediately in front.  At each "mushroom" the sea-plane
curtsied.  Something zipped close to the lad's ear.  A wire snapped,
the severed portions circling themselves into erratic spirals.  A
fragment of fabric from one of the main planes flew past him, like a
scrap of tissue-paper in the grip of a boisterous wind.

Then Ross tumbled to it.  Those silent mushrooms of smoke were shrapnel
shells bursting unpleasantly close.  For a moment, the young observer
felt himself seized by an almost irresistible impulse to take refuge
under the coaming surrounding his seat.  He uttered an involuntary
exclamation of unwelcome surprise.

"What's up?" asked a voice in his ear.  It was the Flight-Sub, to whom
the telephone had transmitted Ross's exclamation.

"Nothing," replied the lad.

"Thought so," was the laconic reply.  "Don't worry."

Reasoning with himself, Ross came to the decision that the advice was
thoroughly sound.  Worrying would not help him in the least; neither
would cowering inside the frail body of the sea-plane.  Twice within a
very short space of time he had experienced a sensation of "funk".
Twice he was surprised to find how quickly he recovered; for, at the
next shot from the monitor for which he was "spotting", he found that
the sensation of "cold feet" had given place to one of exhilaration
when he was able to record a "direct hit".

By this time the initial operations were terminating.  The German fire
had almost ceased to be troublesome.  Most of the big howitzers and
long-range guns had been knocked out.  A few were still firing, but
very erratically.

At a signal from the senior officer, the monitors drew out of range,
and steaming at the maximum speed--a bare 11 knots--kept a course
parallel with the shore, accompanied by the patrol-vessels and
transports.

Well above effective shrapnel range, the squadron of sea-planes headed
for Zeebrugge.  A number of aviatiks, which were flying over the German
new sea base, hurriedly turned tail.  Previous experience had taught
them that naval air-craft could hit hard, in addition to carrying out
observation work.

There were, however, plenty of evidences that the Germans were rushing
up thousands of troops in order to deal with the supposed landing in
force.  Train after train made towards the town, crammed with soldiers.

The sea-planes let the trains pass unhindered.  It was not their
purpose to stop Germans from pouring into Zeebrugge.  Once the troops
were there, then would be the time to cut their lines of communication.

Again the monitors opened fire.  Their reception was hotter than it had
been in the neighbourhood of Ostend, for, in spite of frequent and
destructive molestation, the Germans had succeeded in throwing up
numerous heavily armed and cleverly concealed batteries.

At almost extreme range the British ships maintained a rapid high-angle
fire.  In a few minutes fires had broken out in several places.
Fifteen-hundred-pound shells dropped in the canal basin, blowing to
atoms several submarines that were in the process of fitting out.  The
harbour works were swept by the huge projectiles.  The long curved
breakwater suffered heavily.  Huge gaps appeared in the solid masonry.
Everything lying afloat in the enclosed water was either set on fire or
sunk.  In an hour the havoc wrought at Zeebrugge had wiped out the work
of months.

Ross had little time to notice the work of destruction.  His particular
business was to observe the fire directed upon a large redoubt to the
north-east of the town.  The first shell from the monitor fell short,
blowing an enormous crater in the grass-grown dunes.  The second fell
beyond, completely demolishing a house.  The third dropped fairly in
the centre of the redoubt, causing a terrific explosion that was not
due solely to the lyddite bursting-charge.  The magazine had exploded.

Skywards rushed an enormous cloud of black and yellow smoke.  Caught by
the blast of the violently displaced air the sea-plane rocked, then
began dropping like a stone.

For the moment Ross imagined that the end had come.  He was no longer
afraid.  A sensation of intense curiosity as to what the machine and
its occupants would look like seemed to obsess his mind.

Then, with a jerk that reminded the midshipman of the sudden starting
of a lift, the sea-plane "flattened out" and began to climb out of the
enveloping cloud of smoke.

The Flight-Sub turned his head and grinned broadly.  His manner could
not do otherwise than inspire confidence.  Although not a pilot, he was
master of the frail machine.  Side-slips and nose-dives troubled him
but little, provided he was flying at a safe altitude.

"A jolly good wipe-out!" he exclaimed.  "There won't be many Bosches
left within half a mile of that battery, I'm thinking.  Now watch when
the next shot lands: that will give you the objective."

A sharp buzzing in the receiver attached to Ross's flying helmet
announced that the monitor was "calling up" her observer.  Quickly the
lad seized the pencil, and gave the signal that he was ready to take
down the message.

The Morse signal, when translated into writing, was as follows:--

"Register Position 47."

"Good!" exclaimed the Plight-Sub when Ross had telephoned him the
message.  He consulted his map, which was similar to the one at the
observer's disposal "Position 47: that's a railway junction."

In the course of their work of fortifying Zeebrugge, the Huns had
constructed a double-track railway, passing within a few yards of the
Dutch frontier for several miles before heading straight for the new
submarine base.  Two miles from Zeebrugge the line joined the existing
railway, the junction being recorded on British airmen's maps as
Position 47.

The time was now ripe for the monitor which had successfully demolished
the redoubt to attempt a similar exploit, namely, to destroy the
junction.

The sea-plane's appearance was the signal for a furious fire from the
numerous anti-aircraft guns mounted in the vicinity of the station.

At six thousand feet the risk of being hit was small, while the height
did not prevent the observer making a fairly accurate register of the
hits.

It was a very long range, but the monitor's 14-inch guns did excellent
work.  Seven shells sufficed to reduce the station to a heap of ruins
and blow whole sections of the line to atoms.

Again came a wireless order:

"Sea-plane to proceed to Zwilhuit.  Attempt destruction of bridge
across canal."

Once more the Flight-Sub smiled.  This was work that suited him
immensely.  For the nonce "spotting" was finished with.  The sea-plane
had to drop her cargo of bombs upon an important strategic position.

"All right!" exclaimed the Flying officer.  "Keep a cool head.  When I
give the word, press that pedal under your right foot.  Bend down and
you'll find a safety pin just above the floor.  Remove it, but be jolly
careful not to touch the pedal until I give the word."

Underneath the fuselage were six bombs hanging from an inclined steel
rod.  These were released by means of a rachet operated by the pedal to
which the Flight-Sub had alluded.  To prevent a premature release the
pedal was "locked" by a safety device.  When this was removed, each
depression of the pedal would result in the liberation of a potent
missile of destruction.

The sea-plane was not alone on her errand.  In her wake flew two more,
for the actual bombardment had now ceased, and the air-craft were at
liberty to engage upon a raid several miles inland.

The Huns had not constructed their strategic railway close to the Dutch
frontier without a cunning reason.  Extreme care had to be exercised by
British airmen, since it was an easy matter for a bomb to drop across
the border.  Nothing would please the Germans better, for at once there
would be a case of violation of Dutch territory.  On the other hand,
the Huns had no scruple in mounting a battery of anti-aircraft guns,
training them in such a manner that the earthward flight of spent
shrapnel would assuredly fall upon the Dutch village of Venterloos,
which was separated from Zwilhuit by a distance of less than four
hundred yards.

In twenty minutes the sea-plane's objective came in sight: a broad line
of railway crossing a canal by means of a steel bridge.  It was evident
that the Germans meant this base to be a permanent one, for the bridge
was of massive construction, strong enough to bear the transport of the
heavy 42-centimetre guns, and yet sufficiently high above the waterway
to admit the passage of large lighters with towering deck-cargoes.

"Stand by!" cautioned the Flight-Sub.  "Keep cool.  Do as well as you
have already done, and everything will go like greased lightning."

Volplaning at an acute angle, the sea-plane swooped down upon her
quarry.  Shrapnel shells burst over, in front, behind, and underneath
her.  It seemed impossible that such a frail object could escape
destruction.

At five hundred feet the Flight-Sub checked her downward course.

"Now!" he ordered.  "And again!"

Two puffs of white smoke marked the points of explosion of the powerful
bombs.  One had fallen fifty yards short of the bridge; the other had
burst almost at the junction of the railway lines.

Round spun the sea-plane.  As she turned Ross could discern the second
of the aerial raiders gliding down, while the third was still at a
great altitude.  Before the one in which Ross was flying could again
soar over its target the second sea-plane had dropped three of her
missiles.  All fell close to the bridge.  The work of demolition was
accomplished, for when the smoke and dust cleared away the substantial
fabric had been precipitated, a mass of twisted steel, into the canal.

[Illustration: "THE WORK OF DEMOLITION WAS ACCOMPLISHED"]

"Two more on the station and then we've finished," exclaimed the
Flight-Sub.  "Ready?"

"Ay, ay!" replied Ross.

He turned his head to watch the progress of the other sea-planes.  One
was still maintaining a terrific altitude, and showed no signs of
making a volplane.

The other was nowhere to be seen.  Perhaps it was as well that the
midshipman had not noticed what had befallen her, for a few seconds
previously a shrapnel shell had burst close underneath the chassis.
The explosion had communicated itself to the remaining bombs, with the
result that utter annihilation had overtaken the plucky British airmen
in the moment of their triumph.

Ross's companion had witnessed the catastrophe.  More, his trained eye
had discerned half a dozen small specks in the western sky.  Quickly he
brought his binoculars to bear upon them.  No mistake now; the specks
revealed themselves as German aviatiks intent upon cutting off the
retreat of the two remaining British air-craft.

Not until Ross had dropped the remaining bombs did his companion speak.

"We've a bit of a shooting match on," he announced.  "Get that rifle
ready.  It's under the coaming on your right hand.  Sight at three
hundred yards, and let rip when I give the word."

Ross took up the weapon almost as a matter of course.  After the
excitement of bomb-dropping and being shelled by shrapnel, the approach
of a fleet of Zeppelins would hardly disturb his equanimity.

Already the third sea-plane, having gained a favourable altitude, was
making straight for her numerous opponents.

The Flight-Sub now began to speed his machine up, climbing in short
spirals, so as to gain what was equivalent to the "weather-gauge" in
the sea battles of Nelson's days.

Ross unslipped the rifle.  Mechanically he set the back-sight, and
jerked open the bolt-action to assure himself that the magazine was
charged.  As he did so he became aware that the cartridges were bent
and buckled.  A piece of shrapnel, passing through the side of the
fuselage, had lodged in the magazine of the rifle.  In addition,
although it was possible to withdraw the bolt, the striking-pin had
jammed.  As a weapon the rifle was useless.  By stopping the shrapnel
bullet the rifle had saved Ross from a serious and perhaps mortal wound.

The midshipman was on the point of reporting the disablement of the
weapon, when the motor gave vent to a peculiar cough and abruptly
stopped.  Unknown to the pilot the petrol-tank had been pierced almost
at its lowest point.  The remaining petrol had been used up during the
spiraling process.  The sea-plane was now at an altitude of three
thousand feet; propulsion, except under the force of gravity, was no
longer possible.

The Flight-Sub was quick to act.  Before the hitherto climbing
air-craft began diving tail downwards, he regulated the elevating
planes, and a long volplane ensued.  The sea-plane was bound to come to
earth, but it was not on hostile soil that the airman hoped to alight.
His goal was the ground beyond the seemingly endless line of barbed
wire that marked the frontier between Belgium and Holland.

The anti-aircraft guns had now opened fire, blazing furiously away at
the rapidly descending sea-plane.  The rapidity of her descent saved
her, for, before the time-fuses could be altered to suit the
ever-varying range, the air-craft was well below the bursting-point of
the missiles.  Nothing but a direct hit--a most difficult matter--could
harm her now.

At a thousand feet she passed the border-line.  Still the Archibalds
barked.  Ross could see the Dutch frontier guards bolting for shelter
as the hall of bullets fell on neutral ground.  Not until the sea-plane
was well over the boundary did the guns reluctantly cease fire.

The earth appeared to leap up and meet the descending machine.  It
looked as if a terrific smash were inevitable.  A sea-plane alighting
upon solid ground has a thousand chances against her, for, being
unprovided with landing wheels, she is not adapted to withstand
successfully the impact with the earth.

Cool and collected, the Flight-Sub "flattened her out" to a nicety.  At
forty miles an hour the floats struck the ground.  For twenty yards the
sea-plane skidded, then with a rending crash the floats and a network
of struts and tension-wires gave way under the abnormal strain.  The
next instant Ross found himself sprawling on the sandy soil, the sudden
jerk tearing his securing-belt from its fastenings.

He sat up.  A multitude of dazzling lights seemed to flash before his
eyes.  He was dimly aware of a tangle of wreckage, out of which a
practically undamaged plane rose at an oblique angle, lumbering the
ground quite twenty yards from where he found himself.  Men were
hastening towards the wrecked sea-plane from all directions, but, thank
Heaven, they did not wear the uniform of the Hun.

With his head still whirling, Ross was supported by two Dutch soldiers,
while a third poured a quantity of raw spirits down his throat.  Blood
was streaming from a gash on his forehead, and his knees, grazed and
discoloured, were visible through rents in his trousers.

Of what happened during the next quarter of an hour, the midshipman had
but a very hazy idea.  The men had laid him on the ground, propping him
against a large stone.  He felt horribly sick.  The pain across his
chest, caused by the strain upon the leather belt, was acute--far worse
than the wound on his forehead which the kindly soldiers were bathing
with handkerchiefs dipped in water.

The men were talking excitedly.  He could not understand what they were
saying.  He felt inclined to tell them to shut up.  They irritated him
beyond measure; if only they would go away and leave him in peace he
would be deeply grateful.

Suddenly it dawned upon him that he had been in an awful smash.  The
wrecked sea-plane had not hitherto led the train of his thoughts to the
subject of the accident.  Now he realized his position.

"Where's my companion?" he asked,  "Is he knocked out?"

"Do not yourself fret," said a voice that sounded far away.  "He is
hurt, but badly not at all.  We him have carried away.  I am a doctor.
You quiet must be, and zen recovery rapide will be."

The doctor--a Dutch army surgeon--ran his hands lightly over the lad's
limbs.

"Goot!" he ejaculated.  "Nodings broken is."

He gave directions to the men in attendance.  A stretcher was laid on
the ground beside the lad.  Two men lifted him gently upon it.  Even as
they did so, Ross gave a low groan and passed into merciful oblivion.




CHAPTER XXVII

Not on Parole

"Ver' goot.  I understan' you no give parole?"

"No, sir," replied the Flight-Sub firmly.

"An' you, mynheer?"

"I am in the same boat, sir," replied Ross.

The camp-commandant smiled--a hearty smile, bordering on a laugh.

"Goot, I understan' also," he reiterated.  Then, shaking a podgy little
finger, he added: "Same boat, ah?  English idiomatic expression?  Ver'
well, it is so; but if you make escape, do not let me you catch.  Zat
is all."

A week had elapsed since the involuntary descent of the sea-plane.
Both officers were making rapid progress towards recovery, for, in
spite of the violence of the impact, neither of them had received
anything worse than contusions and bruises.

After three days in hospital at Utrecht, the interned aviators were
transferred to a small concentration camp at the village of Koedijk, a
short distance from Alkmaar.  A few miles to the westward, and beyond
an expanse of sand dunes, was the North Sea.  The temptation to refuse
to give their parole was not to be wondered at, with the call of the
sea so near at hand.  It was, indeed, rather remarkable that the two
officers had not been sent to the large internment camp at Groningen,
where so many of the ill-fated Naval Brigade languished, if not in
captivity, in a state of enforced and tedious detention.

"We'll have to be doubly careful now," remarked the Flight-Sub.  "The
mere fact that we have declined to give our parole will put the
commandant on his guard.  Our best plan will be to mark time for a bit."

"Marking time is always an unsatisfactory business," protested the
energetic Ross.  "Nothing rusts a fellow like inaction.  It wouldn't be
much of a task to tunnel our way out."

The Flight-Sub shook his head.

"Tunnelling's not much good in this water-logged country," he declared.
"We are not water-rats.  Patience, my festive: where there's a will
there's a way."

Their quarters consisted of a long, two-storied building.  The only
other occupants beside the guards, were three British Naval officers
rescued from a mined trawler that had managed to reach Dutch waters
before foundering.  Two of them had broken legs; the third was down
with double pneumonia, the legacy of many a cold, stormy night in the
North Sea.

Surrounding the house was a high brick wall, on which had been recently
placed a triple row of barbed wire.  At the entrance, an archway about
ten feet in height, stood a wooden sentry-box, where a soldier with
rifle and fixed bayonet kept guard in the leisurely manner of the
stolid Dutch menfolk.  One could imagine him, a picturesque figure in
baggy trousers and coat of fantastic cut, smoking his pipe on the quay
at Volendam.  The blue uniform did not form a fitting mantle for his
corpulent form.

The sentry was one of a type.  The rest of the guards--middle-aged men
called up on mobilization--were much of the same build and demeanour.
Their innate love of gossiping tempted them to be on most friendly
terms with the interned officers.  One and all were violently
pro-British.  They had reason to dread the German menace, for they were
level-headed enough to realize that, with the Central Powers
triumphant, the independence of Holland would be a thing of the past.

Adjoining the grounds were the quarters occupied by interned seamen, to
the number of about sixty.  They were strictly guarded; a formidable
double fence of barbed wire, between which armed sentries patrolled,
enclosed the premises.  For discipline, the men were under the orders
of their own petty officers.

"Jolly good luck to you!" exclaimed one of the wounded officers, to
whom the two new-comers confided their intention of escaping.  "If we
three weren't crocked we should have been across the ditch by this
time."

He pointed seawards as he spoke.  From the upper windows of the
building the sunlit sea could be seen.  Beyond the "ditch", as he
termed it, was England and freedom.

"It's no use trying to break out," he continued.  "German spies as
thick as blackberries along the coast.  The most benevolent-looking
mynheer might, as likely as not, be a kultured Hun.  You have to be
smuggled out.  Try your blandishments on old Katje."

"Old who?" asked the Flight-Sub.

"Katje, the old vrouw who calls for the washing.  She comes every
Tuesday and Friday with a cart drawn by dogs, and a basket big enough
to stow the pair of you.  You'll want plenty of palm oil.  There are
the sentries to be squared, and the fellow who provides you with a suit
of 'mufti'.  Wilson, our Lieutenant-Commander, got clear about a month
ago.  He made his way to Ymuiden."

"Wasn't there a row about it?" asked Ross.

"Naturally," replied the wounded officer.  "We had a pretty strenuous
time after it--certain privileges withdrawn and all that sort of thing.
However, when we heard that Wilson had succeeded in making his way to
England we didn't mind that, and things have now recovered their normal
appearance."

On the following Tuesday, Ross and his companion anxiously awaited the
arrival of Vrouw Katje.  At length the old lady--she was nearly
eighty--drove up in style, shouting shrilly to her dogs from her perch
on top of an enormous wicker hamper.

"More washing for you, Katje," announced one of the crippled officers.
"Two more of my countrymen.  They will be very pleased to see you."

Without further ado, Katje ascended the stairs and hammered violently
upon the door of the sitting-room.

Her knowledge of English was good, for earlier in life she was the wife
of the skipper of a bolter that made regular voyages to Hole Haven at
the mouth of the Thames, where a large eel trade was in the hands of
the Dutch fishermen.

"Very well; but I must ask permission of the Commandant," replied
Katje, in perfect good faith, when the Flight-Sub had broached the
subject of being conveyed from the internment camp.

"No, no," protested the young officer in alarm; "that won't do."

"Why not?" persisted the washerwoman.  "Mynheer the Commandant is very
kind."

"Undoubtedly," replied the Flight-Sub.  "But we would much rather that
you wait until we are away from the place before you ask him.  See,
here are five English sovereigns.  They are yours once you get us
clear."

The vrouw shook her head.

"I do not care to," she replied firmly; then without a pause she
continued: "My son-in-law, Jan van Beverwijk, will.  I am sure he will.
Next Friday he will come instead of me.  He is mate of a steamship that
takes the bulbs from Holland to England.  He returns to-morrow, and
sails on Saturday from Ymuiden."

"That sounds excellent," commented the Flight-Sub.

"It is excellent," agreed Katje.  "It will cost you each twenty English
sovereigns."

"But we haven't ten between us."

The vrouw smiled till her weather-beaten face was one mass of deep
wrinkles.

"You English have a proverb about a road," she remarked.

"'It's a long lane that has no turning?'" quoted the officer; but Katje
shook her head.

"'Where there's a will there's a way'," suggested Ross.

"Ah!  That is it.  I knew it was something about a road or a lane.
Way, you call it.  Very well; by next Friday you will find a way."

"Artful old baggage!" exclaimed the Flight-Sub when Katje had taken her
departure.  "She's mighty keen on the rhino.  We'll have to have a whip
round, Trefusis, and give a note of hand."

Their brothers in adversity willingly responded to the call, and before
the eventful Friday a sum in English and Dutch coinage, equivalent to
forty pounds, was ready to be handed to Jan van Beverwijk.

"I wouldn't pay cash on the nail if I were you," suggested the crippled
officer who had been so useful in advising them before.  "Half down,
and the rest when you land in England.  Jan might object, but he'll
give in.  No Dutchman of his standing would shut his eyes to twenty in
hard cash."

At eight o'clock on Friday morning Katje's dog-team romped up; but,
instead of the old vrouw, a lean, leather-faced man with a long coat
reaching to his heels and a flat-topped peak cap strode beside the cart.

At the gate he stopped, and spoke at considerable length with the
sentry.  There was hardly any expression on the faces of the two men as
they talked.  Whether the soldier fell in with the suggestion, Ross,
who was anxiously watching from the window, could not decide.

Presently Jan stooped to fasten the strap of one of his _klompen_, or
wooden shoes; then shouting to the dogs he came towards the house.
Before he had gone very far, the sentry bent and picked up something
that was lying on the spot where Jan had been attending to his footgear.

"Palm oil!" remarked the Flight-Sub laconically.

"Heavy wash to-day," was Jan's greeting as he deposited his heavy
basket in the corridor.  "Spot cash, down on the nail."

"Your knowledge of English is remarkable," said the Flight-Sub affably.

"It has to be," rejoined the Dutchman stolidly.

"We have only twenty pounds," declared the Sub.  "That we will give you
as soon as we are on board and in English waters.  The balance Mr.
Brown will give you on your return, on receipt of a note from us to the
effect that we are safely home."

"It cannot be done," said Jan.

"Then the deal's off," remarked the Flight-Sub coolly; but he
ostentatiously poured the coins from his right hand into his left
before returning them to his pocket.

The Dutchman capitulated.

"Very good," he said.  "I can trust an English Naval officer, although
many a time have I been done in London.  Get in, one of you."

"But the other?" enquired the Sub.

"I am strong, but I am not a Hercules," replied the Dutchman with a
shrug of his shoulders.  "One I can carry to the cart.  To-day is a
heavy wash, so I must return for a second load.  You twig?"

"In you get, Trefusis," ordered his companion, in a tone that would
brook no refusal.

By dint of hunching his shoulders and bending his knees, Ross managed
to get into the basket.  The lid was shut, and Jan, assisted by the
Sub, lifted the heavy load on to his shoulders.

Jolting over the cobble-stones, the cart proceeded at a rapid pace for
nearly a quarter of an hour.  Then Jan called to the dogs to stop.  The
lid was thrown back and Ross told to get out.

He found himself outside a small cottage by the side of a canal.  Katje
was on her knees washing a bundle of clothes; the operation assisted,
with disastrous results to the interned officers' effects, by means of
two large stones with which she pounded the saturated garments.
Without even turning her head to watch the midshipman's exit from the
basket, she proceeded vigorously with her task.

Jan led him into the cottage and pointed to a heap of clothes.

"Put these on you," he said.  "I will now go for your friend."

Before the Flight-Sub rejoined him, Ross was rigged out as a Dutch
youth, in voluminous trousers, long coat, stock, tall cylindrical hat,
green stockings, and wooden shoes.  His companion had to look twice
before he recognized him.

"Now you come with me to Mynheer Guit," said Jan.  "He is a bulb
merchant, and lives just outside Ymuiden.  You will then go on board a
barge that brings the boxes of bulbs from Mynheer Guit's warehouse to
the ship.  I will be with you.  The men in the barge will say nothing.
Before to-night you will be safe on board the _Hoorn_."

Jan was as good as his word.  That night the fugitives slept
comfortably in the cabin of the mate of the steamship _Hoorn_; and at
tide-time, early on Saturday morning while it was still dark, the
vessel glided between the breakwater of Ymuiden, and shaped a course
for the mouth of the Thames.




CHAPTER XXVIII

Almost Recaptured

"What's that light, Jan?" asked the Flight-Sub.

The _Hoorn_ was now well beyond the three-mile limit.  Ross and his
fellow-passenger were standing aft, sheltering from the keen
south-westerly wind.  The mate of the vessel was with them, the skipper
being on the bridge.

"Those lights?" corrected Jan.  "They have been visible all the time.
They are the two white leading-lights to Ymuiden harbour."

"No, I don't mean those," said the Flight-Sub.  "Away to the south'ard,
quite a mile from the harbour.  See, it's showing again."

From the dunes a white light blinked thrice and then disappeared.

"I do not know," answered Jan gravely.  He thought for a moment and
then said: "Half a mo'.  I will speak to the skipper."

"Hanged if I like it," muttered the Flight-Sub.  "I say, Trefusis, that
light blinking away looks very fishy.  It would mean a fifty-pound fine
in England; but here, apparently, it is not objected to."

The skipper and the mate were talking rapidly.  Both men were leaning
over the after side of the bridge-rails, with their eyes fixed upon the
dark shore from which the mysterious light flickered at regular
intervals.

"Light on the port bow," reported the helmsman.  Both of the _Hoorn's_
officers turned just in time to catch sight of a steady white light
before it disappeared.  Whatever its meaning, it was remarkable that
from that moment the shore light ceased to blink.

"Put out our navigation lamps, Jan," said the skipper.  "Someone has
betrayed your English friends.  Nevertheless I will do all in my power
to aid them.  We'll steer south-west for an hour.  Perhaps we may
outwit yon craft, whatever she may be, before dawn."

Ross and his companion were quick to note the alteration of helm.  They
knew, too, that the removal of the steaming-lights was for the purpose
of baffling what must be, to a dead certainty, a German craft--a
submarine, or perhaps a torpedo-boat, since the latter frequently
ventured out of Borkum and crept stealthily towards the Schelde,
keeping close to the Dutch territorial waters in order to avoid being
snapped by the vigilant British destroyer flotilla.

Slowly the wintry day dawned.  Anxiously the British officers scanned
the horizon.  The low-lying Dutch coast was now invisible.  All around
was a waste of grey, tumbling waves, unbroken by a sail of any
description.

The _Hoorn_ was ploughing her way at a modest ten knots.  Short, beamy,
and deep-draughted, she was pitching heavily, sending a frothy bow wave
far to leeward each time she dipped her nose into the steep seas.

"I'd give a fiver for the sight of a good old White Ensign at the
present moment," remarked the Flight-Sub anxiously.  "Good heavens,
what's that?"

Ten seconds later he laughed mirthlessly.

"Nerves going to blazes," he muttered.  "A bit of wreckage gave me the
jumps.  By Jove, don't we look a pair of comical objects?"

They had discarded their grotesque head-dress.  Ross had a woollen
muffler wrapped round his head, while his companion had been given the
loan of a red stocking-cap, but they still retained the weird garb in
which they had made their journey down the ship canal.

Suddenly Ross gripped his companion's arm and pointed with his right
hand to a spar-like object projecting a few feet, close to the waves,
at less than a cable's length on the port quarter.

"A periscope!" ejaculated the Flight-Sub.

"Let's hope it's one of our own submarines," said Ross.

"We'll soon find out," added his companion.  "It's forging ahead.
Whatever it is, they've got us under observation."

Jan, who was now on the bridge, had his attention called to the
disconcerting fact.  He beckoned to his two passengers.

"You had better go below and stow yourselves away," he suggested.  "We
will be boarded before long."

"Not I," replied the Flight-Sub.  "They've marked us already.  If they
do take us they won't have to dig us out of a coal-bunker."

The submarine was emerging.  At a pace that more than held its own with
the _Hoorn_, she shook herself clear of the water, although green seas
were breaking across the flat deck as far aft as the conning-tower.

Then muffled forms clambered through the hatchway; a young,
yellow-bearded officer appeared on the navigation platform and hailed
the _Hoorn_ in Dutch to heave to instantly.

Even then the tough old Dutch skipper was not going to give in without
a protest.

"For what reason?" he shouted back.  "This is a Netherlands ship."

"That I do not doubt," rejoined the officer of the submarine.  "But you
have two Englishmen on board who have broken their parole----"

"You lie!" interrupted the skipper vehemently.

"Not a word more!" exclaimed the German fiercely.  "Heave to, or we
sink you!"

Reluctantly the "old man" gave the order to stop the engines.  Jan,
sliding down the bridge ladder, communicated to the British officers
the text of the conversation.

"Some rascal of a German spy has betrayed you," he added.  "If I could
lay my hands upon him----"

There was a look on the Dutchman's face which showed that his anger was
genuine.

"All right, Jan," said the Flight-Sub.  "It's the fortune of war."

      *      *      *      *      *

"Deucedly rotten morning," remarked Sub-lieutenant Fox as he greeted
the officer of the watch, whom he was about to relieve.

Eccles, the Lieutenant, who had been on the _Capella's_ bridge for four
long and dreary hours, merely nodded sleepily.  He was thinking, with
feelings of satisfaction, of the hot coffee and fragrant bacon and eggs
awaiting him below.  Three minutes had to elapse before eight bells.
Wearily he rubbed his salt-rimmed eyelids with a heavily gloved hand.

"_Taurus_ wirelessed twenty minutes ago," he reported, as the two
officers entered the chart-room.  "She was then at the extreme limit of
her northerly course.  You ought to sight her very shortly.  Here's our
course"--he indicated the pencilled line on the chart.  "Nothing to
report: there never is when I'm officer of the watch.  It's this
infernal monotony that plays havoc with a fellow's nerves."

Noel Fox nodded sympathetically.  Although the _Capella_ had been only
six days on her new station--keeping a watch on the Dutch coast between
the Texel and the North Hinder Lightship--he, too, was mightily "fed
up" with the task of "treading on the tail of Germany's coat".

Not so much as the periscope of a hostile submarine had been sighted.
The German torpedo-boats that occasionally sneaked southwards from
Borkum were taking an enforced holiday.  Perhaps it was in sympathy
with the "High Seas Fleet" skulking in the Kiel Canal.  In any case,
the six motor craft of the _Capella_ class had a full share of wintry
conditions in the North Sea without any compensating adventures to
mitigate the monotony.

As Eccles descended from the bridge, a great-coated muffled-up figure,
followed by a large dog, swung himself up the ladder.

"Morning, Haye," was Noel Fox's salutation, as he stooped to pat Shrap,
the chartered libertine of the _Capella_.  "Dash it all, it is cold!
Makes a fellow wish he were a sheep-dog.  Here, Shrap, off you go and
get your whiskers trimmed.  I can see Tomkins waiting for you."

The dog needed no second order.  Every morning just after eight bells
Shrap would be taken over by the watch below.  Every man took a delight
in combing the animal's long hair, until Shrap's coat was the pride of
the _Capella's_ crew and the envy of the rest of the flotilla, whose
mascots never aspired to be more than a tame rat, parrot, or canary.

"Sail on the port bow, sir," bawled the look-out.

The Sub and the midshipman promptly levelled their telescopes.  A small
cargo-steamer was pitching and rolling as she forged slowly ahead on a
westerly course.  Although she was fairly discernible against the pale
grey of the eastern sky, it could be taken for granted that from the
Dutchman's bridge the neutral-grey-painted _Capella_ would be
practically invisible.

"She's slowing down," declared Vernon.

"What on earth for?" enquired the Sub.  "She couldn't possibly have
spotted us.  Starboard your helm, quartermaster.  Good!  Keep her at
that.  We'll get her to make her number, if nothing else."

Again Noel Fox levelled his telescope.  Then he thrust it into a rack
on the side of the chart-room, and bellowed:

"Turn up, both watches.  Action stations.  Submarine ahead."

His quick glance had discerned the after part of a large unterseeboot
as she ranged alongside the Dutchman, whose high sides screened most of
the submarine from the _Capella_, and conversely prevented the Germans
clustered amidships from noticing the approach of the swift British
patrol-vessel.

For the next few minutes, all was bustle and orderly confusion on board
the _Capella_.  Taking three steps at a time, Captain Syllenger gained
the bridge, closely followed by Eccles, to whom the sudden interruption
of a hearty breakfast came as a welcome call.

At a terrific pace the sleuth-hound of the sea tore towards the
_Hoorn_, for such she was.  Rounding under her squat counter, and
reversing engines, the _Capella_ brought up within fifty yards of the
submarine before the astonished Germans could realize their precarious
plight.

"Surrender, or I sink you!" roared Captain Syllenger.

The grim muzzles of the _Capella's_ 4.7's, trained at a point-blank
range, were a conclusive argument.  Without waiting for orders, the
majority of the unterseeboot's crew held up their arms.  For a brief
instant did her Kapitan hesitate.

"Me surrender," he replied.

"Very good; I accept your surrender," replied the _Capella's_ skipper.
"But understand, any attempt to open the sea-cocks will mean that no
quarter will be given.  Order all hands below, and leave the hatchways
open.  You will oblige me by proceeding on board His Majesty's ship
_Capella_."

By this time the _Hoorn_ was forging ahead, since she was in danger of
drifting down upon the captured submarine.  In the excitement of the
capture, no one on board noticed two grotesquely garbed men on the
_Hoorn_ whose antics resembled those of a pair of demented creatures;
nor was the presence of a couple of dejected German leutnants and five
seamen, stranded on board the Dutchman, observed, as the Huns
frantically besought the obdurate skipper of the _Hoorn_ to steam as
hard as he could towards the Dutch coast.

It was Vernon Haye's duty to take the cutter and board the prize.  It
was a hazardous piece of work, for the sea was now fairly high, and
breaking under the effect of tide against wind; but, with the exception
of a broken top-strake, the boat managed to lie sufficiently close
alongside the submarine to enable the midshipman and five seamen to
board.

Already the German crew were below.  Hatches were lowered and secured,
with the exception of the one in the after side of the conning-tower.
This could be left open without fear of the submarine being swamped,
while, to prevent the captured crew closing it and making an attempt to
dive, the steel cover was removed from its hinges and secured on deck.
The Black Cross flag was hauled down and rehoisted under the White
Ensign, and preparations were made to take the prize in tow.

It was some time before a grass rope, to which a stout wire hawser was
bent, could be veered from the _Capella's_ quarter and taken on board
the submarine, but eventually the hawser was made fast.

"Now, sir," said Vernon, addressing the German Kapitan.  "Will you
please step into that boat?  Where are the other officers?"

"In that ship," replied the Hun sullenly, as he pointed towards the
_Hoorn_.  "They will not welcome you, but there are others who will."

Not knowing what the German meant, Vernon indicated that he should get
on board the cutter.

"There are two German officers on board that vessel, air," reported the
midshipman, as the boat came alongside the _Capella_.  "Am I to bring
them off?"

Captain Syllenger hesitated before replying.  It was a knotty problem.
To remove by force the subjects of a hostile nation from a neutral ship
was contrary to international law.  However much the Germans violated
the "right of search", it was not Great Britain's policy to engage upon
reprisals.  Holland, although a third-rate Power, had to be treated
with due courtesy.

"It's all the same in the long run," replied Captain Syllenger.  "Board
that vessel, Mr. Haye, and see what those fellows are doing there.  If
the Dutch skipper objects to their presence on his hooker, then bundle
them into the boat.  If, on the other hand, he protests against their
removal, let them remain.  They will be collared as soon as the ship
enters our three-mile limit."

The _Hoorn_ had once more come to a dead stop, at two cables' length
from the British patrol-vessel.

As the _Capella's_ cutter came alongside, Vernon agilely scrambled up
the "monkey ladder" and gained the deck.

"Hulloa, old man!" exclaimed a well-known voice.

Vernon looked at the speaker.  He knew the voice, but for a moment he
failed to recognize in the oddly garbed youth his chum Ross Trefusis.
Then he grinned broadly.

"My word!" he exclaimed.  "You do cut a pretty figure."

Had they been of any nationality but British, the lads would have
fallen on each other's necks and perhaps kissed each other.  Instead,
they stood a yard apart and laughed--but their mutual joy was none the
less genuine.

"So you've come to fetch the German Leutnant and his boat's crew," said
Ross, after Haye had been introduced to the Flight-Sub.  "He's
somewhere below.  You'll recognize him right enough."

"Eh?" asked Vernon incredulously.

"Rather!" declared Ross emphatically.  "You'd never guess.  It's our
old pal, Hermann Rix, late of U75.  No wonder he's tearing his hair,
for he must have broken his parole.  He knew me directly he came over
the side, and didn't forget to rub it in.  You should have seen his
face when, in the midst of his beastly gibes, the old _Capella_ came
snorting up."

With Jan acting as interpreter, Vernon put his case before the Dutch
skipper, who seemed only too delighted at the way events had turned.
His satisfaction at getting rid of his Hunnish visitors was evident, in
spite of the stolidity of his manners.

"I want no pirates on board the _Hoorn_," he said.  "Take them and
welcome!"

While the Flight-Sub and Ross were "squaring up" with the good-hearted
Jan, Vernon rounded up Ober-leutnant Rix and his boat's crew.  Finding
that their protests to the Dutch skipper were of no avail, they
sullenly gave in.

"Look here," said Ross, taking his chum aside.  "I don't want to crow
over that fellow.  It isn't cricket.  You might take him to the
_Capella_ and come back for us.  You'll have a pretty good load as it
is."

"Two British officers, escaped from an internment camp, on board the
_Hoorn_, sir," reported Vernon, as he delivered his cargo of German
prisoners on board the _Capella_.  "They would like to be taken off."

"Carry on, then," replied Captain Syllenger.

As the cutter returned from her second trip to the _Hoorn_, the
_Capella's_ crew awaited with undisguised curiosity the arrival of the
men who had contrived to escape from irksome detention in a neutral
country.

Presently Shrap, who was sitting up on the quarterdeck, gave a bark of
delight.

"Good old Shrap!" said Ross.  "He knew me in spite of my rig-out."

"Blow me, if it ain't Mr. Trefusis!" exclaimed one of the men.

The next instant the first of three hearty cheers burst from the
throats of the crew, with whom Ross was a great favourite.  The
Dutchmen, too, joined in, to the accompaniment of a prolonged blast
upon the _Hoorn's_ siren as she resumed her interrupted voyage.

"It's like being home again," declared Ross, after Captain Syllenger
and the other officers had congratulated him.  "But, I say, can anyone
lend me a decent suit of togs?"




CHAPTER XXIX

Bound for the Baltic

A fortnight had elapsed since the day on which H.M.S. _Capella_ towed
the captured unterseeboot into Harwich harbour.  Since then she had
been attached to a base on the East coast of Scotland, her sphere of
usefulness in the English Channel being a thing of the past.

The German blockade had fizzled out like a damp squib.  Absolutely
afraid to risk the remaining boats in operations that would certainly
end in their being unceremoniously conveyed to Davy Jones's locker, the
German Admiralty had dispatched them to the Mediterranean, where, under
the Austrian flag, they attempted, at first with a certain degree of
success, to terrorize merchantmen by their "frightfulness".

So the _Capella_ had been ordered to Cromarty Firth, pending the
completion of arrangements for sending a fleet of swift destroyers and
patrol-boats to operate in conjunction with the British submarines in
the Baltic.

Almost the first duty Ross had to undertake upon arrival was to draw
money for the ship's company from the Paymaster's office at Invergordon.

Accompanied by six seamen, wearing their side-arms and carrying three
canvas bags, the midshipman landed, and proceeded to the office.
Leaving the escort "standing easy", Ross entered the building and found
himself confronted by a door on which was painted the words,
"Accountant Officer".  Underneath was a piece of cardboard on which was
written: "Don't knock--walk in".

The midshipman accepted the invitation and entered.  It was a large
room.  Against one wall were three knee-hole desks, at which were
seated naval "writers"--petty officers detached for clerical work.  Two
more were bending over a large tray, studiously engaged in "putting the
money up", or placing wages in the compartments of the tray in order to
facilitate the forthcoming payment to the civilian workers attached to
the establishment.  At a large desk was an officer, with his head
almost touching a litter of papers.  His back was turned, but Ross
could see by the gold-and-white band that he was an Assistant Paymaster.

Hearing footsteps behind him, the A.P. broke into a torrent of abuse:

"Of all the scatter-brained idiots that act the giddy goat, this
strafed lunatic takes the proverbial ship's biscuit!" he exclaimed.
"Just look here, Carruthers; did you ever see such a piece of arrant
tomfoolery----"

He turned his head, and saw it was not Carruthers.

"Sorry," he said apologetically.  "Thought it was someone else.  You
must have imagined that I was off my head.  It's a wonder I'm not.
Look at this: here am I up to my eyes in work, and I get this sort of
thing fired at me."

Ross looked at the tendered document.  It was headed: "Queries in the
Store Ledger", and the gem to which the harassed A.P. had referred was
as follows:--

"4 oz. tin-tacks.  Please say if these are synonymous with 'tacks
tinned'."

The midshipman laughed.  The A.P. glared.

"Some rotten idiot drawing five hundred a year evidently doesn't
realize it's war-time," he growled.  "Now, what can I do for you?"

At length the midshipman received the necessary coin.  He was about to
leave the officer when he found himself face to face with John Barry,
now a Lieutenant-Commander, R.N.R.

"Bless my soul, Trefusis!" exclaimed Barry cordially.  "I am glad to
see you.  I heard the new _Capella_ was ordered round.  How's everyone?
Thanks, I'm top-hole.  In a deuce of a hurry!  Look here, come on board
and see me to-night.  The _Hunbilker_ is lying off Cromarty.  Can you
manage it?"

"I think so," replied Ross.

"Very good; bring Haye with you.  I'll send a boat at seven bells."

Captain Syllenger readily gave the midshipmen permission.

"It looks as if it might blow a bit before very long," he added.  "If
so, remain on board until morning.  It's no joke making a five-mile
trip in a steamboat on a pitch-dark night with a sea running."

The lads were delighted at the prospect of the visit.  They were both
awfully keen on John Barry; besides, they were rather anxious to see
what sort of command he had.  The ship's name was enough to excite
their curiosity.  She had evidently arrived later than the _Capella_,
for there was no sign of a craft bearing that name when the
patrol-vessel passed Cromarty on the previous afternoon.

Punctually at seven bells a grey motor-boat dashed up alongside the
_Capella's_ gangway.  Shrap, whose instinct told him that his young
master was leaving the ship, anticipated him by making a prodigious
bound from the side into the waiting boat, alighting upon the shoulders
of the coxswain, much to that worthy's astonishment.

"Never mind, sir," replied the man, in answer to Vernon's apologies.
"I've a dog myself at home, very much like this one."

"Let him come with us," suggested Ross.  "He'll kick up an awful row if
you don't."

So Shrap, coiled up in the stern-sheets, had his way.

Having received the midshipmen, the boat turned and threshed its way in
the teeth of a strong easterly breeze.

"Yes, sir, that's the _Hunbilker_," replied the coxswain in answer to
Vernon's query, as a large grey shape loomed through the twilight.

"By Jove!" ejaculated Ross, absolutely taken aback.  "She's a whopper.
Old Barry's got a battleship.  If she isn't a sister ship to the
_Tremendous_, I'm a----"

Fortunately for him, Ross refrained from saying what he might be, for
as things turned out he was wrong.  The _Hunbilker_ commenced her
career as a 6000-ton merchantman, but no one would recognize her as
such.

In all probability, but for the war, she would have ended her career as
such.  But the Navy required her for a certain purpose, and loyally the
old tramp stepped into the breach.  When, after a lapse of nine weeks,
she emerged from the repairing basin, her disguise was complete.  She
looked to be what she was not.  It is, therefore, no cause for
wonderment that the two midshipmen were deceived by the enormous
outlines of what appeared to be a formidable unit of the British Navy.
The _Hunbilker_ was, in short, a maritime ass in lion's skin, but her
role was none the less a responsible one.

"I was rather doubtful whether you would turn up," remarked Barry.
"The glass is dropping like billy-ho, and there's a brute of a sea
tumbling in."

"We need not return to-night," announced Ross.

"That's capital," rejoined the Lieutenant-Commander.  "I'll get the
hands to hoist in the boat and trice the accommodation-ladder up.  We
roll like a barrel in a sea-way."

"You've got a big command this time, sir," said Vernon.

Barry smiled.

"Yes," he replied.  "Plenty of room, but the lighting 'tween decks is
rotten.  All artificial, you know, except the little we get in through
the quarter-deck skylights.  I'm expecting young Jolly; he's the A. P.
you saw ashore at Invergordon.  Not a bad sort of youngster when he's
clear of his work.  Would you like to look round before we go below?"

"Of course the Germans know all about our dummy battleships," continued
Barry as he led the way.  "They jeered at the scheme in the papers as
far back as last November twelvemonth."

"Then what's the object?" asked Ross.

"It muddles them up.  They can't distinguish the _Tremendous_ from this
packet, especially in hazy weather.  They've got to guess which is the
substance and which is the shadow.  From actual results we know now
that the costly experiment has more than justified the expenditure."

The Lieutenant-Commander and his young guests continued to talk shop
until it was time to go below.  From that moment, conversation drifted
into other channels of more or less personal interest.

Presently a loud whistle was heard from without.

"That's Jolly," declared the Lieutenant-Commander.  "It's the last boat
to-night, I fancy."

A few minutes later the A. P., having divested himself of his dripping
oilies and sou'wester, was ushered into the cabin.  Separated from his
duties as Accountant Officer, he was much the same as other men.  Ross
could hardly believe that the jovial officer--for he did not now belie
his name--was the same explosive man who had figuratively lost his head
over four ounces of "tacks tinned".

Dinner over, the four officers drew their chairs close to the fire and
yarned incessantly.  Even the laboured rolling of the ship, the howling
of the wind overhead, and the _chouf chouf_ of the waves as they
slapped against the sides, failed to remind them that they were afloat
and in an exposed anchorage.

"Heard from your sister recently?" enquired Barry, addressing the A. P.
He tried to ask the question in a natural tone of voice, but the
midshipmen were quick to perceive a deepening of the tan in the
Lieutenant-Commander's weather-beaten face.

"Had a letter only this morning," replied Jolly; "a fairly long one,
too.  I suppose things have quieted down a bit after the rush.  My
sister's a double one, you know," he added, turning to Ross and his
chum.

"A what?" asked Ross.

"She's my sister, and she's a nursing sister at a naval hospital,"
explained the A.P.  "There's a very quaint little bit.  I must read it
to you."

He produced an envelope from his pocket.

"'You remember Marjory May?'" he read.  "'She's had her wish.  She
joined here as a probationer, on the day after that terrible destroyer
affair.  We had most of the cases.  One of the patients was a stoker,
who had been knocked about by a shell exploding in a bunker (whatever
that is--it sounds like golf).  Marjorie had her first task--to wash
him before the doctor could operate.  I went to see how she was
progressing, and found the poor girl on the verge of tears.  'Oh,
sister!' she exclaimed; 'I've been scrubbing him for ten minutes, and I
can't get him clean!'  It was rather dull in the ward, so I switched on
the light.  Then I saw the cause of Marjory's distress.  The poor
stoker was a half-caste."

"By Jove!" ejaculated the A.P. as a particularly savage gust laid the
ship well over.  "It isn't half blowing!"

"Yes, my festive friend," agreed Barry; "it is!  Fortunately you are
not due back to-night.  If you were it wouldn't signify, for I wouldn't
order a boat away on a night like this.  To-morrow, if it hasn't
moderated--and the worst is yet to come--we'll weigh and stand up the
Firth into smoother water."

There was a pause in the conversation.  The din without was now
terrific.  One of the worst of the winter gales was approaching its
climax--a furious nor'easter.

"Come in!" shouted Barry as a knock was heard at the cabin door.

"Wireless message, sir," announced one of the ship's boys.

"Very good," replied the Lieutenant-Commander.  Then, after the
messenger had backed out, he started to his feet.

"I say, you fellows!" he exclaimed.  "Here's a pretty kettle of fish:
'Flag to _Hunbilker_: Proceed to sea at once.  Rendezvous Lat. 5 deg. E.,
Long. 57 deg. 30' N.'  That means, whether you like it or whether you
don't, you're bound for the Baltic."




CHAPTER XXX

The Affair off Kiel

Clad in their oilskins over their greatcoats, the two midshipmen
accompanied Barry to the bridge.  The A. P., on second thoughts,
decided to remain below.  He had a rooted objection to getting his
glasses smothered in spray if it could be avoided.

Steam had been raised a week ago, when the _Hunbilker_ left Newcastle
for Cromarty, so there was no delay on that account.  Already the steam
capstan was clanking dolorously as fathom after fathom of chain crept
with seeming reluctance through the hawse-pipe.

It was a night.  Towering seas, sweeping in from the exposed Moray
Firth, surged madly into the more sheltered inlet where the dummy
battleship strained at her cable.  The air was thick with sleet.
Overhead, black clouds scudded rapidly across the moon.

Even though the ship was partly under the lee of the projecting ground,
the midshipmen knew that it would be hopeless to attempt to lower a
boat.  For good or ill they were bound to remain on board.

"Suppose it's all right," remarked Ross.  "We may get a chance of doing
something, far more so than if we were on board the _Capella_, now this
submarine blockade fiasco is finished.  At any rate it's not our fault
we're here."

"But our good fortune," added Vernon.  "Evidently there's a big affair
coming off, though I can't quite see what this vessel's going to do in
it."

For fifteen hours of darkness the _Hunbilker_ plodded steadily onwards.
No lights were shown, yet it was a known fact that at least thirty
vessels of various types were converging upon the rendezvous.

Captain Barry never once quitted the bridge.  Although his lofty post
was constantly deluged by clouds of icy spray, and the weather side of
the bridge-rail canvas was inches deep in sleet, he braved the elements
through watch and watch, snatching a hasty meal of cocoa (which was
cold by the time it reached him) and biscuits under the lee of the
chart-house.

Day dawned at last.  Ross and Vernon, who had gone below to snatch a
few hours' sleep, came on deck to find the _Hunbilker_ at the
rendezvous.  She lay in the midst of a fleet.  There were the great
battle-cruisers, Dreadnoughts and their replicas, light cruisers, and a
galaxy of torpedo-boats--the latter swept from stem to stern by the
waves.

Without any appreciable weakening of the Grand Fleet, this maritime
force had been assembled for particular service--presumably in the
Baltic, although no orders to that effect had yet been received.

All that short January day the fleet steamed slowly eastward, while
signal flags fluttered incessantly.  No hostile submarine put in an
appearance.  Either the Germans feared the swift destroyers that
encircled the large vessels, or else they were in ignorance of the
presence of the British within four hours' steaming of their shores.

It was not until night that the _Hunbilker_ received her orders.  She
had to proceed in advance of the destroyers, and under cover of
darkness pass through the Great Belt.  Having done so, she was to be
run aground on a shoal between the Danish island of Laaland and the
Prussian island of Fehmern, the latter being within forty miles of the
stronghold of the German Navy at Kiel.

Then she was to await developments.  If attacked by submarines, the
British destroyers would dash in; but what the British Admiral fondly
hoped was that the hostile battleships or armoured cruisers would not
be able to resist the temptation of sallying forth from Kiel to give
the supposed Dreadnought her _coup de grace_.  In this case our
submarines would "chip in", and possibly the battle-cruisers might
score with their deadly and accurate long-range salvoes.

"It's not so risky as it looks," commented Barry as he explained the
tactics to the midshipmen.  "You see, they can torpedo us as much as
they like, and blow the dummy sides of the ship to bits piecemeal.  We
can't sink, since we'll be hard aground.  We can't take fire--at least,
it would be quite a job to get any part of her to burn without being
able to keep the flames under control.  Gunnery, of course, puts a
different aspect on the subject.  If the enemy start shelling us with
their heavy guns, then the sooner we abandon ship and clear out the
better, and leave our big cruisers to mop up the Huns."

Grey dawn was breaking when the _Hunbilker_, having made the passage
through the Great Belt, ran gently aground at the spot indicated in the
Admiral's orders.  Away in the sou'west, a glare in the sky that was
rapidly fading with the growing morn indicated the search-lights of the
Kiel defences.  Eastwards, two huge grey shapes loomed ghost-like in
the half-light.  Whether they were British cruisers or decoys, or even
German battleships, Ross could not determine.

The _Hunbilker_ lay with a slight list to starboard.  All around her
the sea was covered with drifting ice.  An utter stillness brooded over
everything.  The silence was in keeping with the scene of desolation.

Suddenly the deafening blast of the _Hunbilker's_ siren rent the air.
It was the prearranged signal that she was in readiness; it was also
her challenge to the Kiel-tied German fleet.

Ten minutes later a lurid flash, followed by a dull booming noise, came
from the nearmost of the two vessels Ross had previously noticed.

"Either mine or torpedo," remarked Barry casually.  "It doesn't
signify.  They won't sink her in a hurry."

"What is she, sir?" asked Vernon.

"Our opposite number, the _Snark_," replied the Lieutenant-Commander.
"See, she's steaming northwards, without any apparent injury.  It will
be our turn before very long."

At frequent intervals the siren shrieked, as if calling to the rest of
the squadron for assistance.  Then out of the rising mist, for with the
break of day a thin pall of vapour rose from the ice-flecked water,
leapt two German torpedo-boats.

"Port side, all hands!" roared Barry.

Officers and crew put the greatest possible distance between them and
the side of the ship exposed to the hostile craft.  Without slackening
speed, the torpedo-boats described a sharp curve.  Their officers must
have wondered why they were not greeted by the stranded battleship's
quick-firers.  As they turned, two gleaming objects flopped
ungracefully from their decks and disappeared with a splash beneath the
surface.  Each boat had fired a torpedo from her broadside tubes.

From the place where the midshipmen stood, they were not able to follow
the track of the formidable missiles; but they had not long to wait.
Both torpedoes struck almost simultaneously--one abreast of the for'ard
dummy turret, the other fifty feet farther aft.

High in the air rose a column of water mingled with fragments of iron
plating; while in their place of hiding the two lads were smothered
with cork-dust and blackened cotton that had been blown from the space
betwixt the outer and inner hulls.

"It's lucky for us that they didn't use their quick-firers," remarked
Barry.  "They would have pulverized us before our destroyers romped up.
By Jove, Haye, that dog of yours looks as though he likes it!  Hulloa!
There you are!"

The Lieutenant-Commander pointed to the southward.  A rift in the mist
disclosed a two-masted, two-funnelled armoured cruiser about two miles
off.

"The _Prinz Heinrich_ or the _Fuerst Bismarck_," declared Barry.  "We've
turned 'em out.  Hope to goodness our little lot will be in time to
snap them up.  Unless I'm much mistaken, there are two more astern of
her."

Almost as he spoke, a spurt of flame rent the dull sky.  Then, to the
accompaniment of a vivid flash and an ear-splitting detonation, a
5.9-inch shell burst against the for'ard dummy turret of the
_Hunbilker_.

When the smoke had cleared away, guns, turret, and conning-tower,
together with a portion of the bridge, had vanished.

"All hands abandon ship!" ordered Barry, as a salvo of light
projectiles flew round, over, and through the decoy.

It was quite time.  Several men had been hit, since there was nothing
to afford complete protection from the hail of shells.  The difficulty
was to find a boat that was seaworthy, since these suffered almost at
once from the flying fragments of metal.

"Hurrah, sir!" shouted one of the men.  "There are our destroyers."

He was right.  Seven British destroyers were tearing through the water,
intent upon giving the Germans the punishment that they had boasted to
inflict upon the strafed Englishmen--a hussar stroke.

Instantly the galling fire ceased.  The German cruiser had all her work
cut out to endeavour to beat off her wasp-like antagonists.

The _Hunbilker_ was doomed.  In spite of elaborate precautions against
fire, she was burning furiously.  Her fo'c'sle was a mass of flames,
generated by the intense heat of the first shell that had struck her.
Smaller fires, too, had started in other parts of the ship.

But help was at hand.  One of the covering destroyers had witnessed her
plight.  Adroitly manoeuvring, she came right alongside the burning
ship.

"Jump, men!" shouted Barry.

There was no time to be lost.  The danger of the flames communicating
with the shells and war-heads on the destroyer's deck was to be taken
into consideration.

"Come on, old man!" exclaimed Ross, as his chum looked anxiously about
him.

"Where's Shrap?" asked Vernon.  "He was here a minute ago."

In the confusion, occasioned by the rush of men to leap upon the
destroyer, the dog had vanished.

Without a word Vernon ran towards the companion leading to the
half-deck.  Above the roar of the flames and the hissing of steam, he
had heard the well-known bark of his pet.

"Silly ass!" muttered Ross; but he, too, followed his chum.

Wreaths of thin smoke were issuing from the companion as Ross gained
the head of the ladder.  Putting his muffler round his mouth, he groped
his way down.  'Tween decks the air was full of smoke.  He could hear
Shrap's insistent bark, and Vernon's voice as, amidst fits of coughing,
he called to his canine companion.

"Whatever is the matter with the brute?" thought Ross, as he fought his
way along the half-deck.

A gaping hole in the ship's side admitted sufficient light to enable
him to discern his comrade backing from one of the cabins.  Shrap was
preceding him, while Vernon was dragging something limp and heavy.  It
was the body of the luckless A. P.

Without a word, for the atmosphere was hot and choky, Ross bore a hand.
Stumbling and slipping, the two lads bore their burden to the
companion, and by dint of much exertion carried Jolly on deck.

"Is he dead?" asked Ross, after he had refilled his lungs with less
smoke-laden air.

"I don't think so," said Vernon.  "It was good old Shrap that found
him."

The A. P. was below when the salvo from the German cruiser struck the
ship.  He had gone to the cabin temporarily allotted to him to obtain
some small but cherished belonging.  A fragment from one of the shells
had inflicted a nasty scalp wound, stretching him senseless upon the
floor.

Had it not been for the sheep-dog, whose sagacity made him recognize
that Jolly was a friend of his master's, the A. P. would have ended his
career in the burning hull of the _Hunbilker_.

"Hurry up!" exclaimed Ross.  "Let's get him aboard the destroyer."

Between them they carried the insensible officer across the
quarter-deck, but as they reached the side abreast the wreckage of the
superstructure they came to an abrupt halt.

The destroyer had sheered off and was out of sight.

"Now what's to be done?" asked Vernon, aghast at the latest turn of
fortune.

They laid the A. P. on the deck and looked over the side.  Still made
fast to the falls was a whaler, with her keel ten feet above water.
When the order had been given to abandon ship, the boat had been
lowered, but the appearance of the destroyer had done away with the
necessity of having to make use of her.

"Lower away!" ordered Ross.

Checking the descent by taking a turn round the cleats, the lads
allowed the whaler to reach the water.  To their satisfaction they
found that she leaked but very little.  Oars and crutches were already
on board, together with mast and sail.

"Down you get," said Ross.  "Let go the after disengaging gear, then
stand by.  I'll let Jolly down to you."

Vernon quickly swarmed down the falls, while his chum carried the A.P.
to the now empty davit.  Taking a few turns with his strong muffler
round the chest of the unconscious man, Ross engaged the hook of the
lower block, and slowly lowered him into Vernon's arms.  Shrap followed
in a similar manner, since the drop was too great for him to leap
without risk of limb.  Then Ross climbed down and gained the boat.  He
was not a minute too soon, for the flames were drawing nearer and the
heat was becoming almost unbearable.

Placing Jolly in the stern-sheets, the lads stepped the mast and
hoisted sail.  Nothing else was in sight, although the rumble of heavy
firing was still audible.

"I'll steer north," declared Ross, who had taken the helm, while Vernon
attended to the A.P.'s ugly wound.  "If we are not picked up by one of
our own boats, we are almost bound to hit one of the Danish islands."

There was but little wind.  What there was, blew from a couple of
points abaft the beam, so that the little craft was able to lie
comfortably upon her course.

At length Jolly opened his eyes.  Somewhat to his companions' amusement
his first words were:

"Dash it all!  Where did I leave my glasses?  Hulloa!  I've been
plugged.  Where am I?"

He attempted to sit up, but promptly subsided upon the gratings in the
stern-sheets, and in a very short time he began to talk incoherently,
and finally dropped off into a fitful slumber.

The fog had now increased in density, so that it was no longer possible
to see more than a hundred yards ahead.  Several vessels moving at high
speed passed within hailing distance, but no reply came to the lads'
shouts.

"There's a hail!" exclaimed Vernon.

Again came the sound of a human voice.  It was a call for aid, and was
uttered in German.

"Steady!" cautioned Vernon, as Ross put the helm down.  "We don't want
to run alongside a cargo of Huns."

"There's only one, I should imagine," replied his chum.  "At any rate
we'll have a look.  If there are too many, we'll sheer off."

Guided by the repeated calls for assistance, the midshipmen came in
sight of a disabled boat.  It had been holed, and was kept afloat only
by some of its air-tanks which had escaped damage.  The gunwales,
jagged by shell-fire, were showing only a few inches above the water.
The stern was almost awash, but the bows rose sufficiently high for the
forefoot to be seen.  Crouching on the for'ard thwart was a German
officer.  He was bareheaded.  The collar of his greatcoat was turned
up.  His face was blanched by the intense cold.  As the whaler
approached and he saw that it was a British one, he held up his hands
in token of surrender.

Dropping to leeward, Ross luffed smartly.  The whaler lost way almost
alongside the waterlogged boat.

Awkwardly the German clambered over the gunwale, for his limbs were
numbed.  Then, as soon as he was safely on board, he drew a revolver
from the pocket of his greatcoat and fired twice in quick succession.

Ross saw his chum throw up his arms and pitch across the centre thwart.
The next instant he felt a stinging pain in his shoulder, as if it were
pierced by a red-hot needle.

"The brute has plugged me!" was the thought that flashed through his
mind, as he subsided heavily upon the grating by the side of the A. P.

He was still conscious, although everything seemed misty.  Up to a
certain point he remembered exactly what happened, for with a sudden
spring Shrap flew at the treacherous Teuton's throat.

Again and again the German fired, wildly and in the air, for the
sheep-dog had him fixed in his unyielding jaws, shaking the fellow like
a rat.  Unable to move a limb, Ross remained conscious until the issue
was decided and victory rested with the devoted Shrap; then his head
dropped upon his chest and everything became a blank.

      *      *      *      *      *

Ross Trefusis recovered consciousness to find himself in hospital on
the East coast.  In the next cot was Jolly, cutting a sorry figure with
his head swathed in surgical bandages.  Vernon was in an adjoining
ward, making a promising recovery from the wound caused by the cowardly
German's bullet that had passed between his ribs, fortunately just
missing his lungs.

It was not until a week later that Ross heard of the manner of his
rescue.  The whaler had been picked up by a destroyer.  In it they
found the three wounded British officers, and a dead German with his
throat fearfully lacerated.  Not only had Shrap saved the situation,
but he had helped still further to save his master's life, for it was
owing to the warmth of the dog's body that Vernon was saved from death
by exposure.

One of the first of visitors to Ross's bedside was John Barry, now
Commander Barry, R.N.R., D.S.O.

"And how did the scrap come off?" asked Ross.

"Fairly well," replied the Commander.  "We bagged a cruiser and a
couple of destroyers.  The old _Hunbilker_ justified her existence, you
see."

"I'm afraid Haye and I are out of the running," remarked Ross
disconsolately.

"Not a bit of it," replied Barry in his breezy way.  "Not a bit of it.
You'll both be as fit as fiddles in a couple of months.  The Navy's
pushing on with the job all right, Ross, but it's slow and sure.
You'll be at it again long before the end."

Ross gave a sigh of satisfaction.

"Sounds promising, sir, doesn't it?" he exclaimed.

Section  2.  Information about the Mission of Project Gutenberg-tm

Project Gutenberg-tm is synonymous with the free distribution of
electronic works in formats readable by the widest variety of computers
including obsolete, old, middle-aged and new computers.  It exists
because of the efforts of hundreds of volunteers and donations from
people in all walks of life.

Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg-tm's
goals and ensuring that the Project Gutenberg-tm collection will
remain freely available for generations to come.  In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg-tm and future generations.

Section 4.  Information about Donations to the Project Gutenberg
Literary Archive Foundation

Project Gutenberg-tm depends upon and cannot survive without wide
spread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine readable form accessible by the widest
array of equipment including outdated equipment.  Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.

The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States.  Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements.  We do not solicit donations in locations
where we have not received written confirmation of compliance.  To
SEND DONATIONS or determine the status of compliance for any
particular state visit www.gutenberg.org/donate

While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.

International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States.  U.S. laws alone swamp our small staff.

Please check the Project Gutenberg Web pages for current donation
methods and addresses.  Donations are accepted in a number of other
ways including checks, online payments and credit card donations.

Section 5.  General Information About Project Gutenberg-tm electronic
works.

Professor Michael S. Hart was the originator of the Project Gutenberg-tm
concept of a library of electronic works that could be freely shared
with anyone.  For forty years, he produced and distributed Project
Gutenberg-tm eBooks with only a loose network of volunteer support.

Project Gutenberg-tm eBooks are often created from several printed
editions, all of which are confirmed as Public Domain in the U.S.
unless a copyright notice is included.  Thus, we do not necessarily
keep eBooks in compliance with any particular paper edition.

Most people start at our Web site which has the main PG search facility:

     www.gutenberg.org

This Web site includes information about Project Gutenberg-tm,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
