+NOTE.
+
+
+In the original negatives of subjects 10 and 12, there are faint dark
+rings immediately surrounding some of the stars in the denser parts of the
+nebulosity. This effect has no doubt been accentuated in the subsequent
+photographic processes. On the plates of these two subjects in the
+completed volume, these rings are very distinct and give rise to a
+suspicion that the effect has been enhanced by the engraver. A critical
+examination of the prints seems to confirm this view. In the original
+proofs these rings were inconspicuous and were not noticed. The processes
+of steel-facing and printing appear to have increased the effect markedly,
+as it is much stronger on the sheets printed for the edition than in any
+of the early proofs.
+
+Inasmuch as these effects were not and could not be discovered until the
+sheets were assembled in Sacramento for binding, it has not been thought
+desirable to delay the issue of the volume for several weeks additional in
+order to have new plates and new prints of these subjects made by the
+distant engraver.

+
+
+PREFACE.
+
+
+When Professor Keeler entered upon the duties of Director of the Lick
+Observatory, on June 1, 1898, he planned to devote his observing time for
+several years to photographing the brighter nebul� and star clusters, with
+the Crossley reflector. The story of his wonderful success with this
+difficult instrument is familiar to all readers of astronomical
+literature: this form of telescope was in effect born again; and his
+contributions to our knowledge of the nebul� were epoch-making.
+
+Professor Keeler's observing programme included one hundred and four
+subjects. At the time of his lamented death, on August 12, 1900,
+satisfactory negatives of two-thirds of the selected objects had been
+secured. The unphotographed objects were mainly those which come into
+observing position in the unfavorable winter and spring months. The
+completion of the programme was entrusted to Assistant Astronomer Perrine.
+The observers were assisted chiefly by Mr. H. K. Palmer, and in smaller
+degree by Messrs. Joel Stebbins, C. G. Dall, R. H. Curtiss and Sebastian
+Albrecht.
+
+Professor Keeler's photographs enabled him to make two discoveries of
+prime importance, not to mention several that are scarcely secondary to
+them.
+
+1st.--"Many thousands of unrecorded nebul� exist in the sky. A
+conservative estimate places the number within reach of the Crossley
+reflector at about 120,000. The number of nebul� in our catalogues is but
+a small fraction of this." [The number already discovered and catalogued
+did not exceed 13,000. Later observations with the Crossley reflector,
+with longer exposure-times and more sensitive plates, render it probable
+that the number of nebul� discoverable with this powerful instrument is of
+the order of half a million.]
+
+2d.--"Most of these nebul� have a spiral structure."
+
+The photographs of the one hundred and four subjects contain the images of
+744 nebul� not previously observed. A catalogue of these is published in
+the present volume. Their positions, which are thought to be accurate
+within 1��, were determined by Messrs. Palmer, Curtiss, and Albrecht.
+
+The main purpose of this volume is to reproduce and make available for
+study, the larger and more interesting nebul� and clusters on the
+programme, sixty-eight in number. The thirty-six subjects not reproduced
+are for the most part small or apparently not of special interest. The
+difficulties attending the reproduction of astronomical photographs by
+mechanical processes are well-known to all who have made the attempt. It
+seems necessary to recognize, at least at present, that delicate details
+of structure will be lost, and that contrasts between very bright and very
+faint regions will be changed, especially if a good sky background is
+preserved; in other words, that the best obtainable reproductions fall far
+short of doing justice to the original photographs. Technical studies
+should be based upon the original negatives or upon copies on glass.
+
+After considerable experimental work, involving several methods and
+several firms, the making of the heliogravure plates and the hand-press
+prints was entrusted to The Photogravure and Color Company of New York
+City. To this firm's continued interest and willingness to act on
+constructive criticism is due much of the excellence of the results.
+
+The expensive reproductions could hardly have been undertaken without the
+generous assistance of the donors mentioned on a preceding page.
+
+Professor Keeler's description of the Crossley reflector, of his methods
+of observing, and of the chief results obtained, was written only a short
+time before his death. It is here republished. Other results of his work
+are described in the several papers to which the footnotes refer.

+THE CROSSLEY REFLECTOR OF THE LICK OBSERVATORY.[1]
+
+By JAMES E. KEELER.
+
+
+The Crossley reflector, at present the largest instrument of its class in
+America, was made in 1879 by Dr. A. A. Common, of London, in order to
+carry out, and test by practical observation, certain ideas of his
+respecting the design of large reflecting telescopes. For the construction
+of the instrument embodying these ideas, and for some fine astronomical
+photographs obtained with it, Dr. Common was awarded the gold medal of the
+Royal Astronomical Society in 1884.
+
+In 1885, Dr. Common, wishing to make a larger telescope on a somewhat
+similar plan, sold the instrument to Edward Crossley, Esq., F. R. A. S.,
+of Halifax, England. Mr. Crossley provided the telescope with a dome of
+the usual form, in place of the sliding roof used by its former owner, and
+made observations with it for some years; but the climate of Halifax not
+being suitable for the best use of such a telescope, he consented, at the
+request of Dr. Holden, then Director of the Lick Observatory, to present
+it to this institution. The funds for transporting the telescope and dome
+to California, and setting them up on Mount Hamilton, were subscribed by
+friends of the Lick Observatory, for the most part citizens of California.
+The work was completed, and the telescope housed in a suitable observatory
+building, in 1895.[2]
+
+On taking charge of the Lick Observatory in 1898, I decided to devote my
+own observing time to the Crossley reflector, although the whole of my
+previous experience had been with refracting telescopes. I was more
+particularly desirous of testing the reflector with my own hands, because
+such preliminary trials of it as had been made had given rise to somewhat
+conflicting opinions as to its merits.[3] The result of my experience is
+given in the following article, which is written chiefly with reference to
+American readers. If I have taken occasion to point out what I regard as
+defects in the design or construction of the instrument, I have done so,
+not from any desire to look a gift horse in the mouth, but in the interest
+of future improvement, and to make intelligible the circumstances under
+which the work of the reflector is now being done and will be done
+hereafter. The most important improvements which have suggested themselves
+have indeed already been made by Dr. Common himself, in constructing his
+five-foot telescope. The three-foot reflector is, in spite of numerous
+idiosyncracies which make its management very different from the
+comparatively simple manipulation of a refractor, by far the most
+effective instrument in the Observatory for certain classes of
+astronomical work. Certainly no one has more reason than I to appreciate
+the great value of Mr. Crossley's generous gift.
+
+
+[Illustration: DOME OF THE CROSSLEY REFLECTOR.]
+
+
+The Crossley dome is about 350 yards from the main Observatory, at the end
+of a long rocky spur which extends from the Observatory summit toward the
+south, and on which are two of the houses occupied by members of the
+Observatory staff. It is below the level of the lowest reservoir,
+"Huyghens," which receives the discharge from the hydraulic machinery of
+the 36-inch refractor, and therefore the water engine furnished by Mr.
+Crossley for turning the dome can not be used, unless a new water
+system--overflow reservoir, pump and windmill--is provided. In this
+respect a better site would have been a point on the south slope of
+"Kepler,"--the middle peak of Mount Hamilton--just above the Huyghens
+reservoir. No addition to the present water system would then have been
+needed. The slope of the mountain at this place might cut off the view of
+the north horizon, but since the telescope can not be turned below the
+pole, this would be a matter of no consequence. Water-power for the dome
+is not, however, really necessary.
+
+The cylindrical walls of the dome, 36-1/4 feet inside diameter, are
+double, and provided with ventilators. Opening into the dome, on the left
+of the entrance, are three small rooms, one of which has been fitted up as
+a photographic dark room, and another, containing a sidereal clock and a
+telephone, which communicates with the main Observatory, as a study, while
+the third is used for tools and storage. There is also a small room for
+the water engine, in case it should be used. The dome is at present
+supplied with water from only the middle reservoir, Kepler, which is
+reserved for domestic purposes and is not allowed to pass through the
+machinery.
+
+The dome itself, 38 feet 9 inches in diameter, is made of sheet-iron
+plates riveted to iron girders. It also carries the wooden gallery,
+ladders, and observing platform, which are suspended from it by iron rods.
+The apparatus for turning the dome consists of a cast-iron circular rack
+bolted to the lower side of the sole-plate, and a set of gears terminating
+in a sprocket-wheel, from which hangs an endless rope. As the dome does
+not turn easily, it has been necessary to multiply the gearing of the
+mechanism so that one arm's-length pull on the rope moves the dome only
+about one inch. In some positions of the telescope the dome can not be
+moved more than six or eight inches at a time without danger of striking
+the tube, and this slowness of motion is then not disadvantageous. It is
+only when the dome has to be moved through a considerable angle, as in
+turning to a fresh object, or in photographing some object which passes
+nearly through the zenith, that the need for a mechanical means of
+rotation is felt.
+
+The observing slit, 6 feet wide, extends considerably beyond the zenith.
+It is closed by a double shutter, which is operated by an endless rope.
+The upper part, within the dome, is also closed by a hood, or shield,
+which serves to protect the telescope from any water that may find its way
+through the shutter, and which is rolled back to the north when
+observations are made near the zenith. I have recently fitted the lower
+half of the slit with a wind-screen, which has proved to be a most useful
+addition. It is made of tarpaulin, attached to slats which slide between
+the two main girders, and is raised or lowered by halliards, which belay
+to cleats on the north rail of the gallery. A more detailed description of
+the dome has been given in an article by Mr. Crossley,[4] from which the
+reduced figure in Fig. 1[5] has been taken.
+
+The mounting of the three-foot reflector has been very completely
+described and illustrated by Dr. Common,[6] so that only a very general
+description need be given here. The most important feature of the
+mounting is that the telescope tube, instead of being on one side of the
+polar axis, as in the usual construction, is central, so that the axis of
+the mirror and the polar axis are in the same line when the telescope is
+directed to the pole. The declination axis is short, and is supported by a
+massive goose-neck bolted to the upper end of the polar axis. The mirror
+is placed just _above_ the declination axis. Its weight, and the weight of
+the whole tube and eye-end, are counterpoised by slabs of lead, placed in
+two iron boxes, between which the goose-neck of the polar axis passes. The
+great advantage of this arrangement, and the controlling principle of the
+design, is that the telescope is perfectly free to pass the meridian at
+all zenith distances. No reversal of the instrument is needed, or is
+indeed possible.
+
+
+[Illustration: THE CROSSLEY REFLECTOR.]
+
+
+For long-exposure photography, the advantage above referred to is obvious,
+but it is attended by certain disadvantages. One of these is that a very
+much larger dome is required than for the usual form of mounting. Another
+is the great amount of dead weight which the axes must carry; for the
+mirror, instead of helping to counterpoise the upper end of the tube, must
+itself be counterpoised. When anything is attached to the eye-end (and in
+astrophysical work one is always attaching things to the eye-end of a
+telescope), from ten to twenty times as much weight must be placed in the
+counterpoise boxes below the declination axis. Where room is to be found
+for the weights required to counterpoise the Bruce spectrograph, is a
+problem which I have not yet succeeded in solving.
+
+In his five-foot reflector, Dr. Common has caused the telescope tube to
+swing between two large ears, which project from the upper end of the
+boiler-like polar axis, the pivots constituting the declination axis being
+near, but above, the lower end of the tube. The mirror, therefore, helps
+to counterpoise the upper end of the tube. This I regard as a distinct
+improvement. The danger of large masses of metal near the mirror injuring
+the definition is, in my opinion, imaginary; at least there is no such
+danger on Mount Hamilton, where the temperature variations are unusually
+small. Experience with the Crossley reflector, as well as with the other
+instruments of the Lick Observatory, shows that the definition depends
+almost entirely on external conditions.
+
+My first trials of the reflector, as first mounted at the Lick
+Observatory, showed that the center of motion was inconveniently high.
+Among other difficulties arising from this circumstance, the spectroscope
+projected beyond the top of the dome, so that it had to be removed before
+the shutter could be closed. In July, 1898, the pier was therefore cut
+down two feet. This brought the eye-end down nearly to the level of the
+gallery rail, where it was at a convenient height for the observer when
+sitting on a camp-stool, and it made all parts of the mounting more
+accessible. Toward the north and south, the range of the telescope, being
+limited in these directions by the construction of the mounting, was not
+affected by the change, but the telescope can not now be used at such low
+altitudes as formerly, near the east and west points of the horizon. The
+only occasion likely to call for the use of the reflector in these
+positions is the appearance of a large comet near the Sun, and, after some
+consideration, I decided to sacrifice these chances for the sake of
+increasing the general usefulness of the instrument. Except in rare cases,
+all observations are made within three hours of the meridian.
+
+To adapt the mounting to the latitude of Mount Hamilton, a wedge-shaped
+casting, shown in the illustration, had been provided, but through some
+error, arising probably from the fact that the telescope had been used in
+two different latitudes in England, the angle of the casting was too
+great. When the pier was cut down its upper surface was therefore sloped
+toward the south, in order to compensate the error in the casting. Plate
+VII shows the instrument very nearly as it is at the present time.
+
+The polar axis of the Crossley reflector is a long, hollow cylinder,
+separated by a space of about one-eighth of an inch from its concentric
+casing. The idea was to fill this space with mercury, and float the
+greater part of the thrust of the axis, the function of a small steel pin
+at the lower end being merely to steady the axis. But this mercury
+flotation, as applied to the Crossley telescope, is a delusion, as I think
+Mr. Crossley had already found. The mercury, it is true, relieves the
+thrust to some extent, but it greatly increases the already enormous side
+pressure on the steel pin at the bottom, thus creating a much greater evil
+than the one it is intended to remedy. The workmen who set up the mounting
+inform me that the small bearing at the lower end of the polar axis is
+badly worn, as I should expect it to be. Instead of putting mercury into
+the space intended for it, I have therefore poured in a pint or so of oil,
+to keep the lower bearing lubricated. For the reasons indicated above, the
+force required to move the telescope in right ascension is perhaps five
+times greater than it should be. The lower end of the polar axis ought to
+be fitted with ball bearings to take the thrust, and with a pair of
+friction wheels on top; but it would be difficult to make these changes
+now. It should be observed that the disadvantages of the mercury flotation
+are considerably greater at Mount Hamilton than at the latitude for which
+the telescope was designed.
+
+
+[Illustration: THE CROSSLEY REFLECTOR.]
+
+
+As already stated above, the range of the telescope is limited on the
+south by the construction of the mounting. The greatest southern
+declination which can be observed is 25�. In England this would doubtless
+mark the limit set by atmospheric conditions, but at Mount Hamilton it
+would be easy to photograph objects 15� farther south, if the telescope
+could be pointed to them.
+
+The original driving-clock having proved to be inefficient, at least
+without an electric control, a new and powerful driving-clock was made by
+the Observatory instrument maker, from designs by Professor Hussey. In its
+general plan it is like that of the 36-inch refractor. The winding
+apparatus, contained in the large casting of the original mounting, has no
+maintaining power, and can not easily be fitted with one. The clock could
+in no case be wound during a photographic exposure, on account of the
+tremors attending the operation, but it would be somewhat more convenient
+to have the stars remain on the plate during the winding. With a little
+practice, however, one can wind the clock without actually stopping it,
+though the object must afterwards be brought back to its place by means of
+the slow motion in right ascension.
+
+Two finders have recently been fitted to the Crossley reflector. One has
+an object-glass of four inches aperture and eight feet six inches focal
+length, with a field of about 1� 2�, which is very nearly the photographic
+field of the main telescope. Its standards are bolted to one of the corner
+tubes of the reflector. The other finder has a three-inch objective and a
+large field. It had not been mounted when the photograph for the plate was
+made.
+
+When a telescope is used for photographing objects near the pole, with
+long exposures, the polar axis must be quite accurately adjusted, for
+otherwise the centers of motion of the stars and of the telescope will not
+agree, and the star images will be distorted. It is true that with a
+double-slide plate-holder, like the one used with the Crossley reflector,
+one star--namely, the guiding star--is forced to remain in a fixed
+position with respect to the plate; but the differential motion of the
+other stars causes them to describe short arcs, or trails, around this
+star as a center. A considerable part of the spring of 1899 was spent in
+efforts to perfect the adjustment of the polar axis, an operation which,
+on account of the peculiar form of the mounting, offers unusual
+difficulties.
+
+In the first plan which was tried, the reflector was used as a transit
+instrument. The inclination of the declination axis was determined with a
+hanging level which had been provided by Mr. Crossley, the hour circle and
+polar axis being very firmly clamped. The clock correction being known
+from the records kept at the Observatory, the collimation and azimuth
+constants were found by the usual formul�. This method failed to give
+satisfactory results, and it was found later that the declination and
+polar axis were not exactly at right angles.
+
+There is only one part of the sky on which the telescope can be reversed;
+namely, the pole. A method which promised well, and on which some time was
+spent, consists in photographing the pole (the declination axis being
+horizontal) by allowing the stars near it to trail for ten or fifteen
+minutes, then turning the polar axis 180� and photographing the pole again
+on the same plate. Half the distance between the images gives the error of
+the polar axis, which, if the plate is properly oriented, is easily
+resolved into horizontal and vertical components; while the distance of
+each image from the center of the plate is this error increased or
+diminished by twice the deviation of the telescope axis. In this case the
+vertical component depends upon the reading of the declination circle, and
+the horizontal component gives the error of collimation. This method
+failed, however, to give consistent results, mainly on account of
+instability of the mirror, and was abandoned.
+
+The use of the large mirror for purposes of adjustment was finally given
+up, and the axis was adjusted by observations of _Polaris_ with the long
+finder, in the usual manner. In order to reach the star at lower
+culmination the finder tube had to be thrown out of parallelism with the
+main telescope.
+
+The base-plate having no definite center of rotation in azimuth, and the
+wedges and crowbars used for moving it being uncertain in their action, a
+watch telescope, provided with a micrometer eyepiece, was firmly secured
+to the mounting throughout these operations, in such manner that a mark on
+the southern horizon could be observed through one of the windows of the
+dome. The errors of the polar axis were finally reduced to within the
+limits of error of observation.
+
+The movable hour circle and driving wheel of the Crossley reflector has
+two sets of graduations. The driving screw having been thrown out of gear,
+the circle is turned until the outer vernier indicates the sidereal time,
+whereupon the driving screw is thrown into gear again. The inner vernier
+is then set to the right ascension of the object which it is desired to
+observe. As an inconsistency, of minor importance, in the design of the
+mounting, I may note that the slow motion in right ascension changes the
+reading of the outer vernier instead of that of the inner one. In
+practice, however, no inconvenience is caused by this construction.
+
+In the early experiments and photographic work with the Crossley
+telescope, irregularities in driving were a source of great annoyance. Dr.
+Roberts, in laying down the conditions which should be fulfilled by a good
+photographic telescope, says that a star should remain bisected by a
+thread in the eyepiece for two minutes at a time. The Crossley telescope
+was so far from fulfilling this condition that a star would not keep its
+place for two consecutive seconds; and the greatest alertness on the part
+of the observer did not suffice to ensure round star images on a
+photographic plate. It was obvious that the fault did not lie with the
+driving clock; in fact, many of the sudden jumps in right ascension, if
+explained in this way, would have required the clock to run backward;
+nevertheless the clock was tested by causing its revolutions to be
+recorded on a chronograph at the main Observatory, together with the beats
+of one of the standard clocks. For this purpose a break-circuit attachment
+was made by Mr. Palmer. The errors of the clock were in this way found to
+be quite small.
+
+The principal source of the irregularities was found in the concealed
+upper differential wheel of the Grubb slow motion. This wheel turned with
+uncertain friction, sometimes rotating on its axis, and sometimes
+remaining at rest. After it was checked the driving was much better, and
+was still farther improved by repairing some defective parts of the train.
+Small irregularities still remain. They seem to be partly due to
+inaccuracies in the cutting of the gears, or of the teeth of the large
+driving wheel, and partly to the springing of the various parts, due to
+the very considerable friction of the polar axis in its bearings. The
+remaining irregularities are so small, however, that they are easily
+corrected by the screws of the sliding plate-holder, and with reasonable
+attention on the part of the observer, round star images are obtained with
+exposures of four hours' duration.
+
+The large mirror, the most important part of the telescope, has an
+aperture of three feet, and a focal length of 17 feet 6.1 inches. It was
+made by Mr. Calver. Its figure is excellent. On cutting off the cone of
+rays from a star, by a knife-edge at the focus, according to the method of
+Foucault, the illumination of the mirror is very uniform, while the star
+disks as seen in an ordinary eyepiece are small and almost perfectly
+round. They are not, I think, quite so good as the images seen with a
+large refractor; still, they are very good indeed, as the following
+observations of double stars, made recently for this purpose, will show.
+
+Several close double stars were examined on the night of April 17, 1900,
+with a power of 620. The seeing was four on a scale of five. The
+magnitudes and distances of the components, as given in the table, are
+from recent observations by Professor Hussey with the 36-inch refractor.

+
+Although the theoretical limit of resolution for a three-foot aperture is
+not reached in these observations, I do not think the mirror can do any
+better.
+
+The small mirror, or flat, at the upper end of the tube, is circular, the
+diameter being nine inches. Its projection on the plane of the
+photographic plate is therefore elliptical; but the projection of the
+mirror and its cell on the plane of the great mirror is very nearly
+circular.
+
+The small mirror, acting as a central stop, has the effect of diminishing
+the size of the central disk of the diffraction pattern, at the expense of
+an increase in the brightness of the system of rings. To this effect may
+be due, in part, the inferiority of the reflector for resolving bright
+doubles, as compared with a refractor of the same aperture. For
+photographic purposes, it is evident that the mirror is practically
+perfect.
+
+The upper end of the tube can be rotated, carrying with it the flat and
+the eye-end. Whenever the position is changed, the mirrors have to be
+re-collimated. In practice it is seldom necessary to touch the adjusting
+screws of the mirrors themselves. The adjustment is effected by means of
+clamping and butting screws on the eye-end, and a change of the line of
+collimation, with respect to the finders and the circles, is avoided. The
+operation is generally referred to, however, as an adjustment of the
+mirrors.
+
+For adjusting the mirrors there are two collimators. One of these is of
+the form devised by Mr. Crossley.[7] It is very convenient in use, and is
+sufficiently accurate for the adjustment of the eye-end when the telescope
+is used for photographic purposes, inasmuch as the exact place where the
+axis of the large mirror cuts the photographic plate is not then a matter
+of great importance, so long as it is near the center. Moreover, as stated
+farther below, the direction of the axis changes during a long exposure.
+The other collimator is of a form originally due, I think, to Dr.
+Johnstone Stoney. It consists of a small telescope, which fits the
+draw-tube at the eye-end. In the focus of the eyepiece are, instead of
+cross-wires, two adjustable terminals, between which an electric spark can
+be passed, generated by a small induction machine, like a replenisher,
+held in the observer's hand. The terminals are at such a distance inside
+the principal focus of the objective, that the light from the spark, after
+reflection from the flat, appears to proceed from the center of curvature
+of the large mirror. The rays are therefore reflected back normally, and
+form an image of the spark which, when the mirrors are in perfect
+adjustment, coincides with the spark itself. The precision of this method
+is very great. It is in fact out of proportion to the degree of refinement
+attained in other adjustments of the reflector, for a slight pressure of
+the hand on the draw-tube, or movement of the telescope to a different
+altitude, instantly destroys the perfection of the adjustment. I have
+provided these collimators with an adapter which fits the photographic
+apparatus, so that one can adjust the mirrors without having to remove
+this apparatus and substitute for it the ordinary eye-end carrying the
+eyepieces.
+
+For visual observation the Crossley telescope is provided with seven
+eyepieces, with powers ranging from 620 downward. The lowest power is only
+60, and consequently utilizes only 12 inches of the mirror, 9 of which are
+covered by the central flat. It is therefore of little value, except for
+finding purposes. The next lowest power utilizes 28 inches of the mirror.
+The other eyepieces call for no remark.
+
+But, while the Crossley reflector would doubtless be serviceable for
+various kinds of visual observations, its photographic applications are
+regarded as having the most importance, and have been chiefly considered
+in deciding upon the different changes and improvements which have been
+made.
+
+The interior of the dome is lighted at night by a large lamp, which is
+enclosed in a suitable box or lantern, fitted with panes of red glass, and
+mounted on a portable stand. In order to diffuse the light in the lower
+part of the dome, where most of the assistant's work is done, the walls
+are painted bright red; while to prevent reflected light from reaching the
+photographic plate, the inner surface of the dome itself, the mounting,
+and the ladders and gallery are painted dead black. The observer is
+therefore in comparative darkness, and not the slightest fogging of the
+plate, from the red light below, is produced during a four-hours'
+exposure. On the few occasions when orthochromatic plates are used the
+lamp need not be lighted.
+
+Experiments have shown that the fogging of the photographic plate, during
+a long exposure, is entirely due to diffuse light from the sky, and is
+therefore unavoidable. For this reason the cloth curtains which lace to
+the corners of the telescope tube, enclosing it and shutting out light
+from the lower part of the dome, have not been used, since their only
+effect would be to catch the wind and cause vibrations of the telescope.
+They would probably have little effect on the definition, and at any rate
+could not be expected to improve it.
+
+For photographing stars and nebul� the Crossley reflector is provided with
+a double-slide plate-holder, of the form invented by Dr. Common.[8] This
+apparatus, which had suffered considerably in transportation, and from
+general wear and tear, was thoroughly overhauled by the Observatory
+instrument-maker. The plates were straightened and the slides refitted. A
+spring was introduced to oppose the right ascension screw and take up the
+lost motion--the most annoying defect that such a piece of apparatus can
+have--and various other improvements were made, as the necessity for them
+became apparent. They are described in detail farther below.
+
+The present appearance of the eye-end is shown in the illustration. The
+plate-holder is there shown, however, on one side of the tube, and its
+longer side is parallel to the axis of the telescope. This is not a good
+position for the eye-end, except for short exposures. In practice, the
+eye-end is always placed on the north or south side of the tube, according
+as the object photographed is north or south of the zenith. The right
+ascension slide is then always at right angles to the telescope axis, and
+the eye-end can not get into an inaccessible position during a long
+exposure.
+
+As the original wooden plate-holders were warped, and could not be
+depended upon to remain in the same position for several hours at a time,
+they were replaced by new ones of metal, and clamping screws were added,
+to hold them firmly in place. The heads of these screws are shown in the
+plate, between the springs which press the plate-holder against its bed.
+
+To illuminate the cross-wires of the guiding eyepiece, a small electric
+lamp is used, the current for which is brought down from the storage
+battery at the main Observatory. The coarse wires have been replaced by
+spider's webs,[9] and reflectors have been introduced, to illuminate the
+declination thread. A collimating lens, placed at its principal focal
+distance from the incandescent filament of the lamp, makes the
+illumination of the wires nearly independent of their position on the
+slide, and a piece of red glass, close to the lens, effectually removes
+all danger of fogging the plate. The light is varied to suit the
+requirements of observation by rotating the reflector which throws the
+light in the direction of the eyepiece.
+
+
+[Illustration: DOUBLE-SLIDE PLATE-HOLDER OF THE CROSSLEY REFLECTOR.]
+
+
+In long exposures it is important for the observer to know at any moment
+the position of the plate with reference to its central or zero position.
+For this purpose scales with indexes are attached to both slides; but as
+they can not be seen in the dark, and, even if illuminated with red light,
+could not be read without removing the eye from the guiding eyepiece, I
+have added two short pins, one of which is attached to the lower side of
+the right ascension slide, and the other to its guide, so that the points
+coincide when the scale reads zero. These pins can be felt by the fingers,
+and with a little practice the observer can tell very closely how far the
+plate is from its central position. It would not be a very difficult
+matter to improve on this contrivance, say by placing an illuminated
+scale, capable of independent adjustment, in the field of the eyepiece,
+but the pins answer every purpose. The declination slide is changed so
+little that no means for indicating its position are necessary.
+
+In this apparatus, as originally constructed, the cross-wires of the
+guiding eyepiece were exactly in the plane of the photographic plate. The
+earlier observations made with the Crossley reflector on Mount Hamilton
+showed that this is not the best position of the cross-wires. The image of
+a star in the guiding eyepiece, which, when in the middle of its slide, is
+nearly three inches from the axis of the mirror, is not round, and its
+shape varies as the eyepiece is pushed in or drawn out. In the plane of
+the photographic plate (assumed to be accurately in focus), it is a
+crescent, with the convex side directed toward the center of the plate.
+This form of image is not suitable for accurate guiding. Outside this
+position the image changes to an arrow-head, the point of which is
+directed toward the axis, and this image can be very accurately bisected
+by the right ascension thread. As the construction of the apparatus did
+not allow the plane of the cross-wires to be changed, the wooden bed of
+the plate-holder was cut down, so as to bring the wires and the plate into
+the proper relative positions.
+
+After some further experience with the instrument, still another change
+was made in this adjustment. It was found that the focus often changed
+very perceptibly during a long exposure, and while the arrow-head image
+above described was suitable for guiding purposes, its form was not
+greatly affected by changes of focus. Between the crescent and the
+arrow-head images there is a transition form, in which two well-defined
+caustic curves in the aberration pattern intersect at an acute angle. The
+intersection of these caustics offers an excellent mark for the
+cross-wires, and is at the same time very sensitive to changes of focus,
+which cause it to travel up or down in the general pattern. The bed of the
+plate-holder was therefore raised, by facing it with a brass plate of the
+proper thickness.
+
+Why the focus of the telescope should change during a long exposure is not
+quite clear. The change is much too great to be accounted for by expansion
+and contraction of the rods forming the tube, following changes of
+temperature, while a simple geometrical construction shows that a drooping
+of the upper end of the tube, increasing the distance of the plate from
+the (unreflected) axis of the mirror, can not displace the focus in a
+direction normal to the plate, if it is assumed that the field is flat.
+The observed effect is probably due to the fact that the focal surface is
+not flat, but curved. During a long exposure, the observer keeps the
+guiding star, and therefore, very approximately, all other stars, in the
+same positions relatively to the plate; but he has no control over the
+position of the axis of the mirror, which, by changes of flexure, wanders
+irregularly over the field. The position of maximum curvature, therefore,
+also varies, and with it the focus of the guiding star relatively to the
+cross-wires, where the focal surface is considerably inclined to the field
+of view. It is certain that the focus does change considerably, whatever
+the cause may be, and that the best photographic star images are obtained
+by keeping the focus of the guiding star unchanged during the exposures.
+This is done by turning the focusing screw of the eye-end.
+
+In making the photographs of nebul� for which the Crossley telescope is at
+present regularly employed, it was at first our practice to adjust the
+driving-clock as accurately as possible to a sidereal rate, and then, when
+the star had drifted too far from its original position, on account of
+changes of rate or of flexure, to bring it back by the right-ascension
+slow motion, the observer either closing the slide of the plate-holder or
+following the motion of the star as best he could with the right-ascension
+screw. Lately a more satisfactory method, suggested by Mr. Palmer, has
+been employed. The slow motion in right ascension is of Grubb's form,[10]
+and the telescope has two slightly different rates, according to whether
+the loose wheel is stopped or allowed to turn freely. The driving-clock is
+adjusted so that one of these rates is too fast, the other too slow. At
+the beginning of an exposure the wheel is, say, unclamped, and the guiding
+star begins to drift very slowly toward the left, the observer following
+it with the screw of the plate-holder. When it has drifted far enough, as
+indicated by the pins mentioned farther above, the wheel is clamped. The
+star then reverses its motion and begins to drift toward the right; and so
+on throughout the exposure. The advantages of this method over the one
+previously employed are, that the star never has to be moved by the slow
+motion of the telescope, and that its general drift is in a known
+direction, so that its movements can be anticipated by the observer. In
+this way photographs are obtained, with four hours' exposure, on which the
+smallest star disks are almost perfectly round near the center of the
+plate, and from 2�� to 3�� in diameter.
+
+The star images are practically round over a field at least 1 inch or 16�
+in diameter. Farther from the center they become parabolic, but they are
+quite good over the entire plate, 3-1/4 by 4-1/4 inches.
+
+From these statements it will be seen that small irregularities in driving
+no longer present any difficulties. But certain irregular motions of the
+image still take place occasionally, and so far it has not been possible
+entirely to prevent their occurrence.
+
+It was found that the declination clamp (the long slow-motion handle
+attached to which is shown in the illustration) was not sufficiently
+powerful to hold the telescope firmly during a long exposure. A screw
+clamp was therefore added, which forces the toothed-declination sector
+strongly against an iron block just behind it, thus restoring, I think,
+the original arrangement of the declination clamp as designed by Dr.
+Common. This clamp holds the tube very firmly.
+
+The irregularities to which I have referred consist in sudden and
+unexpected jumps of the image, which always occur some time after the
+telescope has passed the meridian. These jumps are sometimes quite
+large--as much as one-sixteenth of an inch or 1. They are due to two
+causes: flexure of the tube, and sliding of the mirror on its bed. When
+the jump is due to sudden changes of flexure, the image moves very
+quickly, and vibrates before it comes to rest in its new position, and at
+the same time there is often heard a slight ringing sound from the tension
+rods of the tube. There seems to be no remedy for the sudden motions of
+this class. The tension rods are set up as tightly as possible without
+endangering the threads at their ends or buckling the large corner tubes.
+A round telescope tube, made of spirally-wound steel ribbon riveted at the
+crossings, would probably be better than the square tube now in use.
+
+Jumps due to shifting of the mirror are characterized by a gentle, gliding
+motion. They can be remedied, in part, at least, by tightening the copper
+bands which pass around the circumference of the mirror within its cell.
+This will be done the next time the mirror is resilvered.
+
+All that the observer can do when a jump occurs is to bring back the image
+as quickly as possible to the intersection of the cross-wires. If all the
+stars on the plate are faint, no effect will be produced on the
+photograph; but stars of the eighth magnitude or brighter will leave short
+trails. The nebula, if there is one on the plate, will, of course, be
+unaffected.
+
+Before beginning an exposure the focus is adjusted by means of a
+high-power positive eyepiece. An old negative, from which the film has
+been partially scraped, is placed in one of the plate-holders, and the
+film is brought into the common focus of the eyepiece and the great
+mirror. The appearance of the guiding star, which varies somewhat with the
+position of the guiding eyepiece on its slide, is then carefully noted,
+and is kept constant during the exposure by turning, when necessary, the
+focusing screw of the eye-end. For preliminary adjustments a ground-glass
+screen is often convenient. On it all the _DM._ stars, and even
+considerably fainter ones, as well as the nebul� of Herschel's Class I,
+are easily visible without a lens.
+
+Plates are backed, not more than a day or two before use, with Carbutt's
+"Columbian backing," which is an excellent preparation for this purpose.
+During the exposure the observer and assistant exchange places every half
+hour, thereby greatly relieving the tediousness of the work, though two
+exposures of four hours each, in one night, have proved to be too
+fatiguing for general practice. At the end of the first two hours it is
+necessary to close the slide and wind the clock.
+
+The brightness of the guiding star is a matter of some importance. If the
+star is too bright, its glare is annoying; if it is too faint, the effort
+to see it strains the eye, and changes of focus are not easily recognized.
+A star of the ninth magnitude is about right. In most cases a suitable
+star can be found without difficulty.
+
+In such an apparatus as that described above, the amount by which the
+plate may be allowed to depart from its zero position is subject to a
+limitation which has not, I think, been pointed out, although it is
+sufficiently obvious when one's attention has been called to it. It
+depends upon the fact that the plate necessarily moves as a whole, in a
+straight line which is tangent to a great circle of the sphere, while the
+stars move on small circles around the pole. The compensation for drift,
+when the plate is moved, is therefore exact at the equator only.
+
+Let the guiding star have the declination [Greek: delta]_{1}, and let a
+star on the upper edge of the plate (which, when the telescope is north of
+the zenith, and the eye-end is on the north side of the telescope, will be
+the southern edge) have the declination [Greek: delta]_{2}. Then if the
+guiding star is allowed to drift from its zero position through the
+distance _d_, the other star will drift through the distance _d_ (cos
+[Greek: delta]_{2} / cos [Greek: delta]_{1}). If the guiding star is
+followed by turning the right-ascension screw, the upper edge of the
+plate, as well as the guiding eyepiece, will be moved through the distance
+_d_. Hence there will be produced an elongation of the upper star,
+represented by
+
+  _e_ = _d_ ((cos [Greek: delta]_{2} / cos [Greek: delta]_{1}) - 1)
+
+  from which _d_ = (_e_ cos [Greek: delta]_{1}) /
+                    (cos [Greek: delta]_{2} - cos [Greek: delta_{1}]).
+
+Now, in the Crossley reflector, the upper edge of the plate and the
+guiding eyepiece are just about 3-2/3 inches, or 1�, apart. If _e_ is
+given, the above formula serves to determine the maximum range of the
+slide for different positions of the telescope.
+
+It has been stated farther above that the smallest star disks, on a good
+photograph, are sometimes not more than 2�� in diameter, or in a linear
+measure, about 1/20 mm. An elongation of this amount is therefore
+perceptible. There are many nebul� in high northern declinations, and
+there are several particularly fine ones in about +70�. If, therefore, we
+take [Greek: delta]_{2} = 70�, [Greek: delta]_{1}, = 71�, _e_ = 0.05, and
+substitute these values, we find _d_ = 1.0 mm, which is the greatest
+permissible range of the plate in photographing these nebul�. Before I
+realized the stringency of this requirement, by making the above simple
+computation, I spoiled several otherwise fine negatives by allowing the
+plate to get too far from the center, thus producing elongated star
+images.
+
+There is a corresponding elongation in declination, the amount of which
+can be determined by an adaptation of the formula for reduction to the
+meridian, but it is practically insensible.
+
+On account of the short focal length of the three-foot mirror, the
+photographic resolving power of the telescope is much below its optical
+resolving power. For this reason the photographic images are less
+sensitive to conditions affecting the seeing than the visual images. On
+the finest nights the delicate tracery of bright lines or caustic curves
+in the guiding star is as clear and distinct as in a printed pattern. When
+the seeing is only fair these delicate details are lost, and only the
+general form of the image, with its two principal caustics, is seen. A
+photograph taken on such a night is not, however, perceptibly inferior to
+one taken when the seeing is perfect. When, however, the image is so
+blurred that its general form is barely distinguishable, the photographic
+star disks are likewise blurred and enlarged, and on such nights
+photographic work is not attempted.
+
+The foregoing account of the small changes which have been made in the
+Crossley telescope and its accessories may appear to be unnecessarily
+detailed, yet these small changes have greatly increased the practical
+efficiency of the instrument, and, therefore, small as they are, they are
+important. Particularly with an instrument of this character, the
+difference between poor and good results lies in the observance of just
+such small details as I have described.
+
+At present the Crossley reflector is being used for photographing nebul�,
+for which purpose it is very effective. Some nebul� and clusters, like the
+great nebula in _Andromeda_ and the _Pleiades_, are too large for its
+plate (3-1/4 � 4-1/4 in.), but the great majority of nebul� are very much
+smaller, having a length of only a few minutes of arc, and a large-scale
+photograph is required to show them satisfactorily. It is particularly
+important to have the images of the involved stars as small as they can be
+made.
+
+Many nebul� of Herschel's I and II classes are so bright that fairly good
+photographs can be obtained with exposures of from one to two hours; but
+the results obtained with full-light action are so superior to these, that
+longer exposures of three and one half or four hours are always preferred.
+In some exceptional cases, exposures of only a few minutes are sufficient.
+The amount of detail shown, even in the case of very small nebul�, is
+surprising. It is an interesting fact that these photographs confirm (in
+some cases for the first time) many of the visual observations made with
+the six-foot reflector of the Earl of Rosse.
+
+Incidentally, in making these photographs, great numbers of new nebul�
+have been discovered. The largest number that I have found on any one
+plate is thirty-one. Eight or ten is not an uncommon number, and few
+photographs have been obtained which do not reveal the existence of three
+or four. A catalogue of these new objects will be published in due time.
+
+Some of the results obtained with the Crossley reflector, relating chiefly
+to particular objects of some special interest, have already been
+published.[11] The photographs have also permitted some wider conclusions
+to be drawn, which are constantly receiving further confirmation as the
+work progresses. They may be briefly summarized as follows:
+
+1. Many thousands of unrecorded nebul� exist in the sky. A conservative
+estimate places the number within reach of the Crossley reflector at about
+120,000. The number of nebul� in our catalogues is but a small fraction of
+this.
+
+2. These nebul� exhibit all gradations of apparent size, from the great
+nebula in _Andromeda_ down to an object which is hardly distinguishable
+from a faint star disk.
+
+3. Most of these nebul� have a spiral structure.
+
+To these conclusions I may add another, of more restricted significance,
+though the evidence in favor of it is not yet complete. Among the objects
+which have been photographed with the Crossley telescope are most of the
+"double" nebul� figured in Sir John Herschel's catalogue (_Phil. Trans._,
+1833, Plate XV). The actual nebul�, as photographed, have almost no
+resemblance to the figures. They are, in fact, spirals, sometimes of very
+beautiful and complex structure; and, in any one of the nebul�, the
+secondary nucleus of Herschel's figure is either a part of the spiral
+approaching the main nucleus in brightness, or it can not be identified
+with any real part of the object. The significance of this somewhat
+destructive conclusion lies in the fact that these figures of Herschel
+have sometimes been regarded as furnishing analogies for the figures which
+Poincar� had deduced, from theoretical considerations, as being among the
+possible forms assumed by a rotating fluid mass; in other words, they have
+been regarded as illustrating an early stage in the development of double
+star systems. The actual conditions of motion in these particular nebul�,
+as indicated by the photographs, are obviously very much more complicated
+than those considered in the theoretical discussion.
+
+While I must leave to others an estimate of the importance of these
+conclusions, it seems to me that they have a very direct bearing on many,
+if not all, questions concerning the cosmogony. If, for example, the
+spiral is the form normally assumed by a contracting nebulous mass, the
+idea at once suggests itself that the solar system has been evolved from a
+spiral nebula, while the photographs show that the spiral nebula is not,
+as a rule, characterized by the simplicity attributed to the contracting
+mass in the nebular hypothesis. This is a question which has already been
+taken up by Professor Chamberlin and Mr. Moulton of the University of
+Chicago.
+
+The Crossley reflector promises to be useful in a number of fields which
+are fairly well defined. It is clearly unsuitable for photographing the
+Moon and planets, and for star charting. On the other hand, it has proved
+to be of value for finding and photographically observing asteroids whose
+positions are already approximately known.
+
+One of the most fruitful fields for this instrument is undoubtedly stellar
+spectroscopy. Little has been done in this field, as yet, with the
+Crossley reflector, but two spectrographs, with which systematic
+investigations will be made, have nearly been completed by the Observatory
+instrument-maker. One of these, constructed with the aid of a fund given
+by the late Miss C. W. Bruce, has a train of three 60� prisms and one 30�
+prism, and an aperture of two inches; the other, which has a single quartz
+prism, will, I have reason to expect, give measurable, though small,
+spectra of stars nearly at the limit of vision of the telescope.
+
+The photogravure[12] of the Trifid nebula, which accompanies this article,
+was made from a photograph taken with the Crossley reflector on July 6,
+1899, with an exposure of three hours. It was not selected as a specimen
+of the work of the instrument, for the negative was made in the early
+stages of the experiments that I have described, and the star images are
+not good, but rather on account of the interest of the subject. At the
+time the photogravures were ordered no large scale photograph of the
+Trifid nebula had, so far as I am aware, ever been published.[13] The
+remarkable branching structure of the nebula is fairly well shown in the
+photogravure, though less distinctly than in the transparency from which
+it was made. The enlargement, as compared with the original negative, is
+2.9 diameters (1 mm = 13��). The fainter parts of the nebula would be
+shown more satisfactorily by a longer exposure.

+
+[3] The difficulties here referred to, about which a good deal has been
+written, seem to have had their origin in the fact that it was impossible,
+at the time of the preliminary trials, to provide the observer with an
+assistant, while the Crossley reflector is practically unmanageable by a
+single person.

+
+[8] _Mon. Not. R. A. S._, =49=, 297. The construction here described is
+not followed exactly in the Crossley apparatus. The guiding eyepiece
+slides freely when not held by a clamp. Pin-holes for preventing fogging
+are unnecessary when red light is used.
+
+[9] It so happens that the tension of the vertical thread is such that it
+begins to slacken when the temperature falls to within about 2� of the dew
+point. The thread thus forms an excellent hygrometer, which is constantly
+under the eye of the observer. When the thread becomes slack, it is time
+to cover the mirrors.

+
+1.B.  "Project Gutenberg" is a registered trademark.  It may only be

+agree to be bound by the terms of this agreement.  There are a few
+things that you can do with most Project Gutenberg-tm electronic works

+
+1.C.  The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works.  Nearly all the individual works in the
+collection are in the public domain in the United States.  If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed.  Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work.  You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D.  The copyright laws of the place where you are located also govern
+what you can do with this work.  Copyright laws in most countries are in
+a constant state of change.  If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work.  The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.
+
+1.E.  Unless you have removed all references to Project Gutenberg:
+
+1.E.1.  The following sentence, with active links to, or other immediate
+access to, the full Project Gutenberg-tm License must appear prominently
+whenever any copy of a Project Gutenberg-tm work (any work on which the

+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+
+This eBook is for the use of anyone anywhere at no cost and with
+almost no restrictions whatsoever.  You may copy it, give it away or
+re-use it under the terms of the Project Gutenberg License included
+with this eBook or online at www.gutenberg.org
+
+1.E.2.  If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges.  If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the
+Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
+1.E.9.
+
+1.E.3.  If an individual Project Gutenberg-tm electronic work is posted
+with the permission of the copyright holder, your use and distribution
+must comply with both paragraphs 1.E.1 through 1.E.7 and any additional
+terms imposed by the copyright holder.  Additional terms will be linked
+to the Project Gutenberg-tm License for all works posted with the
+permission of the copyright holder found at the beginning of this work.
+
+1.E.4.  Do not unlink or detach or remove the full Project Gutenberg-tm
+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.
+
+1.E.5.  Do not copy, display, perform, distribute or redistribute this
+electronic work, or any part of this electronic work, without
+prominently displaying the sentence set forth in paragraph 1.E.1 with
+active links or immediate access to the full terms of the Project
+Gutenberg-tm License.
+
+1.E.6.  You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form.  However, if you provide access to or
+distribute copies of a Project Gutenberg-tm work in a format other than
+"Plain Vanilla ASCII" or other format used in the official version
+posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
+you must, at no additional cost, fee or expense to the user, provide a
+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original "Plain Vanilla ASCII" or other
+form.  Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.

+     the use of Project Gutenberg-tm works calculated using the method
+     you already use to calculate your applicable taxes.  The fee is
+     owed to the owner of the Project Gutenberg-tm trademark, but he
+     has agreed to donate royalties under this paragraph to the
+     Project Gutenberg Literary Archive Foundation.  Royalty payments
+     must be paid within 60 days following each date on which you

+     address specified in Section 4, "Information about donations to
+     the Project Gutenberg Literary Archive Foundation."
+
+- You provide a full refund of any money paid by a user who notifies
+     you in writing (or by e-mail) within 30 days of receipt that s/he
+     does not agree to the terms of the full Project Gutenberg-tm
+     License.  You must require such a user to return or
+     destroy all copies of the works possessed in a physical medium
+     and discontinue all use of and all access to other copies of
+     Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+     money paid for a work or a replacement copy, if a defect in the
+     electronic work is discovered and reported to you within 90 days
+     of receipt of the work.
+
+- You comply with all other terms of this agreement for free

+
+1.E.9.  If you wish to charge a fee or distribute a Project Gutenberg-tm
+electronic work or group of works on different terms than are set
+forth in this agreement, you must obtain permission in writing from
+both the Project Gutenberg Literary Archive Foundation and Michael
+Hart, the owner of the Project Gutenberg-tm trademark.  Contact the
+Foundation as set forth in Section 3 below.
+
+1.F.
+
+1.F.1.  Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection.  Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2.  LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees.  YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3.  LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a
+written explanation to the person you received the work from.  If you
+received the work on a physical medium, you must return the medium with
+your written explanation.  The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund.  If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund.  If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4.  Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
+WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
+
+1.F.5.  Some states do not allow disclaimers of certain implied
+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law.  The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.
+
+1.F.6.  INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,
+promotion and distribution of Project Gutenberg-tm electronic works,
+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+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.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3.  Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service.  The Foundation's EIN or federal tax identification
+number is 64-6221541.  Its 501(c)(3) letter is posted at
+http://pglaf.org/fundraising.  Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+
+The Foundation's principal office is located at 4557 Melan Dr. S.
+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations.  Its business office is located at

+business@pglaf.org.  Email contact links and up to date contact

+page at http://pglaf.org
+
+For additional contact information:
+     Dr. Gregory B. Newby
+     Chief Executive and Director
+     gbnewby@pglaf.org
+
+
+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 http://pglaf.org
+
+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.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5.  General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone.  For thirty 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:
+
+     http://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.

+
+<div class="note">
+<p>In the original negatives of subjects 10 and 12, there are faint dark
+rings immediately surrounding some of the stars in the denser parts of the
+nebulosity. This effect has no doubt been accentuated in the subsequent
+photographic processes. On the plates of these two subjects in the
+completed volume, these rings are very distinct and give rise to a
+suspicion that the effect has been enhanced by the engraver. A critical
+examination of the prints seems to confirm this view. In the original
+proofs these rings were inconspicuous and were not noticed. The processes
+of steel-facing and printing appear to have increased the effect markedly,
+as it is much stronger on the sheets printed for the edition than in any
+of the early proofs.</p>
+
+<p>Inasmuch as these effects were not and could not be discovered until the
+sheets were assembled in Sacramento for binding, it has not been thought
+desirable to delay the issue of the volume for several weeks additional in
+order to have new plates and new prints of these subjects made by the
+distant engraver.</p>

+<h2>PREFACE.</h2>
+
+<p>When Professor Keeler entered upon the duties of Director of the Lick
+Observatory, on June 1, 1898, he planned to devote his observing time for
+several years to photographing the brighter nebul&aelig; and star clusters, with
+the Crossley reflector. The story of his wonderful success with this
+difficult instrument is familiar to all readers of astronomical
+literature: this form of telescope was in effect born again; and his
+contributions to our knowledge of the nebul&aelig; were epoch-making.</p>
+
+<p>Professor Keeler&#8217;s observing programme included one hundred and four
+subjects. At the time of his lamented death, on August 12, 1900,
+satisfactory negatives of two-thirds of the selected objects had been
+secured. The unphotographed objects were mainly those which come into
+observing position in the unfavorable winter and spring months. The
+completion of the programme was entrusted to Assistant Astronomer Perrine.
+The observers were assisted chiefly by Mr. H. K. Palmer, and in smaller
+degree by Messrs. Joel Stebbins, C. G. Dall, R. H. Curtiss and Sebastian
+Albrecht.</p>
+
+<p>Professor Keeler&#8217;s photographs enabled him to make two discoveries of
+prime importance, not to mention several that are scarcely secondary to
+them.</p>
+
+<p>1st.&mdash;&#8220;Many thousands of unrecorded nebul&aelig; exist in the sky. A
+conservative estimate places the number within reach of the Crossley
+reflector at about 120,000. The number of nebul&aelig; in our catalogues is but
+a small fraction of this.&#8221; [The number already discovered and catalogued
+did not exceed 13,000. Later observations with the Crossley reflector,
+with longer exposure-times and more sensitive plates, render it probable
+that the number of nebul&aelig; discoverable with this powerful instrument is of
+the order of half a million.]</p>
+
+<p>2d.&mdash;&#8220;Most of these nebul&aelig; have a spiral structure.&#8221;</p>
+
+<p>The photographs of the one hundred and four subjects contain the images of
+744 nebul&aelig; not previously observed. A catalogue of these is published in
+the present volume. Their positions, which are thought to be accurate
+within 1&Prime;, were determined by Messrs. Palmer, Curtiss, and Albrecht.</p>
+
+<p>The main purpose of this volume is to reproduce and make available for
+study, the larger and more interesting nebul&aelig; and clusters on the
+programme, sixty-eight in number. The thirty-six subjects not reproduced
+are for the most<span class="pagenum"><a name="Page_8" id="Page_8">[Pg 8]</a></span> part small or apparently not of special interest. The
+difficulties attending the reproduction of astronomical photographs by
+mechanical processes are well-known to all who have made the attempt. It
+seems necessary to recognize, at least at present, that delicate details
+of structure will be lost, and that contrasts between very bright and very
+faint regions will be changed, especially if a good sky background is
+preserved; in other words, that the best obtainable reproductions fall far
+short of doing justice to the original photographs. Technical studies
+should be based upon the original negatives or upon copies on glass.</p>
+
+<p>After considerable experimental work, involving several methods and
+several firms, the making of the heliogravure plates and the hand-press
+prints was entrusted to The Photogravure and Color Company of New York
+City. To this firm&#8217;s continued interest and willingness to act on
+constructive criticism is due much of the excellence of the results.</p>
+
+<p>The expensive reproductions could hardly have been undertaken without the
+generous assistance of the donors mentioned on a preceding page.</p>
+
+<p>Professor Keeler&#8217;s description of the Crossley reflector, of his methods
+of observing, and of the chief results obtained, was written only a short
+time before his death. It is here republished. Other results of his work
+are described in the several papers to which the footnotes refer.</p>

+<h2>THE CROSSLEY REFLECTOR OF THE LICK OBSERVATORY.<span class="foot"><a name="f1.1" id="f1.1" href="#f1">[1]</a></span></h2>
+<p class="center">By <span class="smcap">James E. Keeler</span>.</p>
+
+<p>The Crossley reflector, at present the largest instrument of its class in
+America, was made in 1879 by Dr. A. A. Common, of London, in order to
+carry out, and test by practical observation, certain ideas of his
+respecting the design of large reflecting telescopes. For the construction
+of the instrument embodying these ideas, and for some fine astronomical
+photographs obtained with it, Dr. Common was awarded the gold medal of the
+Royal Astronomical Society in 1884.</p>
+
+<p>In 1885, Dr. Common, wishing to make a larger telescope on a somewhat
+similar plan, sold the instrument to Edward Crossley, Esq., F. R. A. S.,
+of Halifax, England. Mr. Crossley provided the telescope with a dome of
+the usual form, in place of the sliding roof used by its former owner, and
+made observations with it for some years; but the climate of Halifax not
+being suitable for the best use of such a telescope, he consented, at the
+request of Dr. Holden, then Director of the Lick Observatory, to present
+it to this institution. The funds for transporting the telescope and dome
+to California, and setting them up on Mount Hamilton, were subscribed by
+friends of the Lick Observatory, for the most part citizens of California.
+The work was completed, and the telescope housed in a suitable observatory
+building, in 1895.<small><a name="f2.1" id="f2.1" href="#f2">[2]</a></small></p>
+
+<p>On taking charge of the Lick Observatory in 1898, I decided to devote my
+own observing time to the Crossley reflector, although the whole of my
+previous experience had been with refracting telescopes. I was more
+particularly desirous of testing the reflector with my own hands, because
+such preliminary trials of it as had been made had given rise to somewhat
+conflicting opinions as to its merits.<small><a name="f3.1" id="f3.1" href="#f3">[3]</a></small> The result of my experience is
+given in the following article, which is written chiefly with reference to
+American readers. If I have taken occasion to point out what I regard as
+defects in the design or construction of the instrument, I have done so,
+not from any desire to look a gift horse in the mouth, but in the interest
+of future improvement, and to make intelligible the circumstances under
+which the work of the reflector is now being done and will be done
+hereafter. The most important improvements which have suggested themselves
+have indeed already<span class="pagenum"><a name="Page_12" id="Page_12">[Pg 12]</a></span> been made by Dr. Common himself, in constructing his
+five-foot telescope. The three-foot reflector is, in spite of numerous
+idiosyncracies which make its management very different from the
+comparatively simple manipulation of a refractor, by far the most
+effective instrument in the Observatory for certain classes of
+astronomical work. Certainly no one has more reason than I to appreciate
+the great value of Mr. Crossley&#8217;s generous gift.</p>
+
+<p>&nbsp;</p>
+<div class="bbox" style="width: 500px; height: 397px;"><img src="images/img_pg12.jpg" alt="" /></div>
+<p class="center">DOME OF THE CROSSLEY REFLECTOR.</p>
+<p>&nbsp;</p>
+
+<p>The Crossley dome is about 350 yards from the main Observatory, at the end
+of a long rocky spur which extends from the Observatory summit toward the
+south, and on which are two of the houses occupied by members of the
+Observatory staff. It is below the level of the lowest reservoir,
+&#8220;Huyghens,&#8221; which receives the discharge from the hydraulic machinery of
+the 36-inch refractor, and therefore the water engine furnished by Mr.
+Crossley for turning the dome can not be used, unless a new water
+system&mdash;overflow reservoir, pump and windmill&mdash;is provided. In this
+respect a better site would have been a point on the south slope of
+&#8220;Kepler,&#8221;&mdash;the middle peak of Mount Hamilton&mdash;just above the Huyghens
+reservoir. No addition to the present water system would then have been
+needed. The<span class="pagenum"><a name="Page_13" id="Page_13">[Pg 13]</a></span> slope of the mountain at this place might cut off the view of
+the north horizon, but since the telescope can not be turned below the
+pole, this would be a matter of no consequence. Water-power for the dome
+is not, however, really necessary.</p>
+
+<p>The cylindrical walls of the dome, 36&#188; feet inside diameter, are
+double, and provided with ventilators. Opening into the dome, on the left
+of the entrance, are three small rooms, one of which has been fitted up as
+a photographic dark room, and another, containing a sidereal clock and a
+telephone, which communicates with the main Observatory, as a study, while
+the third is used for tools and storage. There is also a small room for
+the water engine, in case it should be used. The dome is at present
+supplied with water from only the middle reservoir, Kepler, which is
+reserved for domestic purposes and is not allowed to pass through the
+machinery.</p>
+
+<p>The dome itself, 38 feet 9 inches in diameter, is made of sheet-iron
+plates riveted to iron girders. It also carries the wooden gallery,
+ladders, and observing platform, which are suspended from it by iron rods.
+The apparatus for turning the dome consists of a cast-iron circular rack
+bolted to the lower side of the sole-plate, and a set of gears terminating
+in a sprocket-wheel, from which hangs an endless rope. As the dome does
+not turn easily, it has been necessary to multiply the gearing of the
+mechanism so that one arm&#8217;s-length pull on the rope moves the dome only
+about one inch. In some positions of the telescope the dome can not be
+moved more than six or eight inches at a time without danger of striking
+the tube, and this slowness of motion is then not disadvantageous. It is
+only when the dome has to be moved through a considerable angle, as in
+turning to a fresh object, or in photographing some object which passes
+nearly through the zenith, that the need for a mechanical means of
+rotation is felt.</p>
+
+<p>The observing slit, 6 feet wide, extends considerably beyond the zenith.
+It is closed by a double shutter, which is operated by an endless rope.
+The upper part, within the dome, is also closed by a hood, or shield,
+which serves to protect the telescope from any water that may find its way
+through the shutter, and which is rolled back to the north when
+observations are made near the zenith. I have recently fitted the lower
+half of the slit with a wind-screen, which has proved to be a most useful
+addition. It is made of tarpaulin, attached to slats which slide between
+the two main girders, and is raised or lowered by halliards, which belay
+to cleats on the north rail of the gallery. A more detailed description of
+the dome has been given in an article by Mr. Crossley,<small><a name="f4.1" id="f4.1" href="#f4">[4]</a></small> from which the
+reduced figure in Fig. 1<small><a name="f5.1" id="f5.1" href="#f5">[5]</a></small> has been taken.</p>
+
+<p>The mounting of the three-foot reflector has been very completely
+described and illustrated by Dr. Common,<small><a name="f6.1" id="f6.1" href="#f6">[6]</a></small> so that only a very general
+description need be<span class="pagenum"><a name="Page_14" id="Page_14">[Pg 14]</a></span> given here. The most important feature of the
+mounting is that the telescope tube, instead of being on one side of the
+polar axis, as in the usual construction, is central, so that the axis of
+the mirror and the polar axis are in the same line when the telescope is
+directed to the pole. The declination axis is short, and is supported by a
+massive goose-neck bolted to the upper end of the polar axis. The mirror
+is placed just <i>above</i> the declination axis. Its weight, and the weight of
+the whole tube and eye-end, are counterpoised by slabs of lead, placed in
+two iron boxes, between which the goose-neck of the polar axis passes. The
+great advantage of this arrangement, and the controlling principle of the
+design, is that the telescope is perfectly free to pass the meridian at
+all zenith distances. No reversal of the instrument is needed, or is
+indeed possible.</p>
+
+<p>&nbsp;</p>
+<div class="figcenter"><img src="images/img_pg14.jpg" alt="" /></div>
+<p class="center">THE CROSSLEY REFLECTOR.</p>
+<p>&nbsp;</p>
+
+<p>For long-exposure photography, the advantage above referred to is obvious,
+but it is attended by certain disadvantages. One of these is that a very
+much larger dome is required than for the usual form of mounting. Another
+is the great amount of dead weight which the axes must carry; for the
+mirror, instead of helping to counterpoise the upper end of the tube, must
+itself be counterpoised. When anything is attached to the eye-end (and in
+astrophysical work one is always attaching things to the eye-end of a
+telescope), from ten to twenty times as much weight must be placed in the
+counterpoise boxes below the declination axis. Where room is to be found
+for the weights required to counterpoise the Bruce spectrograph, is a
+problem which I have not yet succeeded in solving.</p>
+
+<p>In his five-foot reflector, Dr. Common has caused the telescope tube to
+swing between two large ears, which project from the upper end of the
+boiler-like polar axis, the pivots constituting the declination axis being
+near, but above, the lower end of the tube. The mirror, therefore, helps
+to counterpoise the upper end of the<span class="pagenum"><a name="Page_15" id="Page_15">[Pg 15]</a></span> tube. This I regard as a distinct
+improvement. The danger of large masses of metal near the mirror injuring
+the definition is, in my opinion, imaginary; at least there is no such
+danger on Mount Hamilton, where the temperature variations are unusually
+small. Experience with the Crossley reflector, as well as with the other
+instruments of the Lick Observatory, shows that the definition depends
+almost entirely on external conditions.</p>
+
+<p>My first trials of the reflector, as first mounted at the Lick
+Observatory, showed that the center of motion was inconveniently high.
+Among other difficulties arising from this circumstance, the spectroscope
+projected beyond the top of the dome, so that it had to be removed before
+the shutter could be closed. In July, 1898, the pier was therefore cut
+down two feet. This brought the eye-end down nearly to the level of the
+gallery rail, where it was at a convenient height for the observer when
+sitting on a camp-stool, and it made all parts of the mounting more
+accessible. Toward the north and south, the range of the telescope, being
+limited in these directions by the construction of the mounting, was not
+affected by the change, but the telescope can not now be used at such low
+altitudes as formerly, near the east and west points of the horizon. The
+only occasion likely to call for the use of the reflector in these
+positions is the appearance of a large comet near the Sun, and, after some
+consideration, I decided to sacrifice these chances for the sake of
+increasing the general usefulness of the instrument. Except in rare cases,
+all observations are made within three hours of the meridian.</p>
+
+<p>To adapt the mounting to the latitude of Mount Hamilton, a wedge-shaped
+casting, shown in the illustration, had been provided, but through some
+error, arising probably from the fact that the telescope had been used in
+two different latitudes in England, the angle of the casting was too
+great. When the pier was cut down its upper surface was therefore sloped
+toward the south, in order to compensate the error in the casting. Plate
+VII shows the instrument very nearly as it is at the present time.</p>
+
+<p>The polar axis of the Crossley reflector is a long, hollow cylinder,
+separated by a space of about one-eighth of an inch from its concentric
+casing. The idea was to fill this space with mercury, and float the
+greater part of the thrust of the axis, the function of a small steel pin
+at the lower end being merely to steady the axis. But this mercury
+flotation, as applied to the Crossley telescope, is a delusion, as I think
+Mr. Crossley had already found. The mercury, it is true, relieves the
+thrust to some extent, but it greatly increases the already enormous side
+pressure on the steel pin at the bottom, thus creating a much greater evil
+than the one it is intended to remedy. The workmen who set up the mounting
+inform me that the small bearing at the lower end of the polar axis is
+badly worn, as I should expect it to be. Instead of putting mercury into
+the space intended for it, I have therefore poured in a pint or so of oil,
+to keep the lower bearing lubricated. For the reasons indicated above, the
+force required to move the telescope in right<span class="pagenum"><a name="Page_16" id="Page_16">[Pg 16]</a></span> ascension is perhaps five
+times greater than it should be. The lower end of the polar axis ought to
+be fitted with ball bearings to take the thrust, and with a pair of
+friction wheels on top; but it would be difficult to make these changes
+now. It should be observed that the disadvantages of the mercury flotation
+are considerably greater at Mount Hamilton than at the latitude for which
+the telescope was designed.</p>
+
+<p>&nbsp;</p>

+<p class="center">THE CROSSLEY REFLECTOR.</p>
+<p>&nbsp;</p>
+
+<p>As already stated above, the range of the telescope is limited on the
+south by the construction of the mounting. The greatest southern
+declination which can be observed is 25&deg;. In England this would doubtless
+mark the limit set by atmospheric conditions, but at Mount Hamilton it
+would be easy to photograph objects 15&deg; farther south, if the telescope
+could be pointed to them.</p>
+
+<p><span class="pagenum"><a name="Page_17" id="Page_17">[Pg 17]</a></span>The original driving-clock having proved to be inefficient, at least
+without an electric control, a new and powerful driving-clock was made by
+the Observatory instrument maker, from designs by Professor Hussey. In its
+general plan it is like that of the 36-inch refractor. The winding
+apparatus, contained in the large casting of the original mounting, has no
+maintaining power, and can not easily be fitted with one. The clock could
+in no case be wound during a photographic exposure, on account of the
+tremors attending the operation, but it would be somewhat more convenient
+to have the stars remain on the plate during the winding. With a little
+practice, however, one can wind the clock without actually stopping it,
+though the object must afterwards be brought back to its place by means of
+the slow motion in right ascension.</p>
+
+<p>Two finders have recently been fitted to the Crossley reflector. One has
+an object-glass of four inches aperture and eight feet six inches focal
+length, with a field of about 1&deg; 2&prime;, which is very nearly the photographic
+field of the main telescope. Its standards are bolted to one of the corner
+tubes of the reflector. The other finder has a three-inch objective and a
+large field. It had not been mounted when the photograph for the plate was
+made.</p>
+
+<p>When a telescope is used for photographing objects near the pole, with
+long exposures, the polar axis must be quite accurately adjusted, for
+otherwise the centers of motion of the stars and of the telescope will not
+agree, and the star images will be distorted. It is true that with a
+double-slide plate-holder, like the one used with the Crossley reflector,
+one star&mdash;namely, the guiding star&mdash;is forced to remain in a fixed
+position with respect to the plate; but the differential motion of the
+other stars causes them to describe short arcs, or trails, around this
+star as a center. A considerable part of the spring of 1899 was spent in
+efforts to perfect the adjustment of the polar axis, an operation which,
+on account of the peculiar form of the mounting, offers unusual
+difficulties.</p>
+
+<p>In the first plan which was tried, the reflector was used as a transit
+instrument. The inclination of the declination axis was determined with a
+hanging level which had been provided by Mr. Crossley, the hour circle and
+polar axis being very firmly clamped. The clock correction being known
+from the records kept at the Observatory, the collimation and azimuth
+constants were found by the usual formul&aelig;. This method failed to give
+satisfactory results, and it was found later that the declination and
+polar axis were not exactly at right angles.</p>
+
+<p>There is only one part of the sky on which the telescope can be reversed;
+namely, the pole. A method which promised well, and on which some time was
+spent, consists in photographing the pole (the declination axis being
+horizontal) by allowing the stars near it to trail for ten or fifteen
+minutes, then turning the polar axis 180&deg; and photographing the pole again
+on the same plate. Half the distance between the images gives the error of
+the polar axis, which, if the plate is properly oriented, is easily
+resolved into horizontal and vertical components;<span class="pagenum"><a name="Page_18" id="Page_18">[Pg 18]</a></span> while the distance of
+each image from the center of the plate is this error increased or
+diminished by twice the deviation of the telescope axis. In this case the
+vertical component depends upon the reading of the declination circle, and
+the horizontal component gives the error of collimation. This method
+failed, however, to give consistent results, mainly on account of
+instability of the mirror, and was abandoned.</p>
+
+<p>The use of the large mirror for purposes of adjustment was finally given
+up, and the axis was adjusted by observations of <i>Polaris</i> with the long
+finder, in the usual manner. In order to reach the star at lower
+culmination the finder tube had to be thrown out of parallelism with the
+main telescope.</p>
+
+<p>The base-plate having no definite center of rotation in azimuth, and the
+wedges and crowbars used for moving it being uncertain in their action, a
+watch telescope, provided with a micrometer eyepiece, was firmly secured
+to the mounting throughout these operations, in such manner that a mark on
+the southern horizon could be observed through one of the windows of the
+dome. The errors of the polar axis were finally reduced to within the
+limits of error of observation.</p>
+
+<p>The movable hour circle and driving wheel of the Crossley reflector has
+two sets of graduations. The driving screw having been thrown out of gear,
+the circle is turned until the outer vernier indicates the sidereal time,
+whereupon the driving screw is thrown into gear again. The inner vernier
+is then set to the right ascension of the object which it is desired to
+observe. As an inconsistency, of minor importance, in the design of the
+mounting, I may note that the slow motion in right ascension changes the
+reading of the outer vernier instead of that of the inner one. In
+practice, however, no inconvenience is caused by this construction.</p>
+
+<p>In the early experiments and photographic work with the Crossley
+telescope, irregularities in driving were a source of great annoyance. Dr.
+Roberts, in laying down the conditions which should be fulfilled by a good
+photographic telescope, says that a star should remain bisected by a
+thread in the eyepiece for two minutes at a time. The Crossley telescope
+was so far from fulfilling this condition that a star would not keep its
+place for two consecutive seconds; and the greatest alertness on the part
+of the observer did not suffice to ensure round star images on a
+photographic plate. It was obvious that the fault did not lie with the
+driving clock; in fact, many of the sudden jumps in right ascension, if
+explained in this way, would have required the clock to run backward;
+nevertheless the clock was tested by causing its revolutions to be
+recorded on a chronograph at the main Observatory, together with the beats
+of one of the standard clocks. For this purpose a break-circuit attachment
+was made by Mr. Palmer. The errors of the clock were in this way found to
+be quite small.</p>
+
+<p>The principal source of the irregularities was found in the concealed
+upper differential wheel of the Grubb slow motion. This wheel turned with
+uncertain<span class="pagenum"><a name="Page_19" id="Page_19">[Pg 19]</a></span> friction, sometimes rotating on its axis, and sometimes
+remaining at rest. After it was checked the driving was much better, and
+was still farther improved by repairing some defective parts of the train.
+Small irregularities still remain. They seem to be partly due to
+inaccuracies in the cutting of the gears, or of the teeth of the large
+driving wheel, and partly to the springing of the various parts, due to
+the very considerable friction of the polar axis in its bearings. The
+remaining irregularities are so small, however, that they are easily
+corrected by the screws of the sliding plate-holder, and with reasonable
+attention on the part of the observer, round star images are obtained with
+exposures of four hours&#8217; duration.</p>
+
+<p>The large mirror, the most important part of the telescope, has an
+aperture of three feet, and a focal length of 17 feet 6.1 inches. It was
+made by Mr. Calver. Its figure is excellent. On cutting off the cone of
+rays from a star, by a knife-edge at the focus, according to the method of
+Foucault, the illumination of the mirror is very uniform, while the star
+disks as seen in an ordinary eyepiece are small and almost perfectly
+round. They are not, I think, quite so good as the images seen with a
+large refractor; still, they are very good indeed, as the following
+observations of double stars, made recently for this purpose, will show.</p>
+
+<p>Several close double stars were examined on the night of April 17, 1900,
+with a power of 620. The seeing was four on a scale of five. The
+magnitudes and distances of the components, as given in the table, are
+from recent observations by Professor Hussey with the 36-inch refractor.</p>

+
+<p>Although the theoretical limit of resolution for a three-foot aperture is
+not reached in these observations, I do not think the mirror can do any
+better.</p>
+
+<p>The small mirror, or flat, at the upper end of the tube, is circular, the
+diameter being nine inches. Its projection on the plane of the
+photographic plate is therefore elliptical; but the projection of the
+mirror and its cell on the plane of the great mirror is very nearly
+circular.</p>
+
+<p>The small mirror, acting as a central stop, has the effect of diminishing
+the size of the central disk of the diffraction pattern, at the expense of
+an increase in the brightness of the system of rings. To this effect may
+be due, in part, the inferiority of the reflector for resolving bright
+doubles, as compared with a refractor of the same aperture. For
+photographic purposes, it is evident that the mirror is practically
+perfect.</p>
+
+<p>The upper end of the tube can be rotated, carrying with it the flat and
+the eye-end. Whenever the position is changed, the mirrors have to be
+re-collimated. In practice it is seldom necessary to touch the adjusting
+screws of the mirrors<span class="pagenum"><a name="Page_20" id="Page_20">[Pg 20]</a></span> themselves. The adjustment is effected by means of
+clamping and butting screws on the eye-end, and a change of the line of
+collimation, with respect to the finders and the circles, is avoided. The
+operation is generally referred to, however, as an adjustment of the
+mirrors.</p>
+
+<p>For adjusting the mirrors there are two collimators. One of these is of
+the form devised by Mr. Crossley.<small><a name="f7.1" id="f7.1" href="#f7">[7]</a></small> It is very convenient in use, and is
+sufficiently accurate for the adjustment of the eye-end when the telescope
+is used for photographic purposes, inasmuch as the exact place where the
+axis of the large mirror cuts the photographic plate is not then a matter
+of great importance, so long as it is near the center. Moreover, as stated
+farther below, the direction of the axis changes during a long exposure.
+The other collimator is of a form originally due, I think, to Dr.
+Johnstone Stoney. It consists of a small telescope, which fits the
+draw-tube at the eye-end. In the focus of the eyepiece are, instead of
+cross-wires, two adjustable terminals, between which an electric spark can
+be passed, generated by a small induction machine, like a replenisher,
+held in the observer&#8217;s hand. The terminals are at such a distance inside
+the principal focus of the objective, that the light from the spark, after
+reflection from the flat, appears to proceed from the center of curvature
+of the large mirror. The rays are therefore reflected back normally, and
+form an image of the spark which, when the mirrors are in perfect
+adjustment, coincides with the spark itself. The precision of this method
+is very great. It is in fact out of proportion to the degree of refinement
+attained in other adjustments of the reflector, for a slight pressure of
+the hand on the draw-tube, or movement of the telescope to a different
+altitude, instantly destroys the perfection of the adjustment. I have
+provided these collimators with an adapter which fits the photographic
+apparatus, so that one can adjust the mirrors without having to remove
+this apparatus and substitute for it the ordinary eye-end carrying the
+eyepieces.</p>
+
+<p>For visual observation the Crossley telescope is provided with seven
+eyepieces, with powers ranging from 620 downward. The lowest power is only
+60, and consequently utilizes only 12 inches of the mirror, 9 of which are
+covered by the central flat. It is therefore of little value, except for
+finding purposes. The next lowest power utilizes 28 inches of the mirror.
+The other eyepieces call for no remark.</p>
+
+<p>But, while the Crossley reflector would doubtless be serviceable for
+various kinds of visual observations, its photographic applications are
+regarded as having the most importance, and have been chiefly considered
+in deciding upon the different changes and improvements which have been
+made.</p>
+
+<p>The interior of the dome is lighted at night by a large lamp, which is
+enclosed in a suitable box or lantern, fitted with panes of red glass, and
+mounted on a portable stand. In order to diffuse the light in the lower
+part of the dome, where most<span class="pagenum"><a name="Page_21" id="Page_21">[Pg 21]</a></span> of the assistant&#8217;s work is done, the walls
+are painted bright red; while to prevent reflected light from reaching the
+photographic plate, the inner surface of the dome itself, the mounting,
+and the ladders and gallery are painted dead black. The observer is
+therefore in comparative darkness, and not the slightest fogging of the
+plate, from the red light below, is produced during a four-hours&#8217;
+exposure. On the few occasions when orthochromatic plates are used the
+lamp need not be lighted.</p>
+
+<p>Experiments have shown that the fogging of the photographic plate, during
+a long exposure, is entirely due to diffuse light from the sky, and is
+therefore unavoidable. For this reason the cloth curtains which lace to
+the corners of the telescope tube, enclosing it and shutting out light
+from the lower part of the dome, have not been used, since their only
+effect would be to catch the wind and cause vibrations of the telescope.
+They would probably have little effect on the definition, and at any rate
+could not be expected to improve it.</p>
+
+<p>For photographing stars and nebul&aelig; the Crossley reflector is provided with
+a double-slide plate-holder, of the form invented by Dr. Common.<small><a name="f8.1" id="f8.1" href="#f8">[8]</a></small> This
+apparatus, which had suffered considerably in transportation, and from
+general wear and tear, was thoroughly overhauled by the Observatory
+instrument-maker. The plates were straightened and the slides refitted. A
+spring was introduced to oppose the right ascension screw and take up the
+lost motion&mdash;the most annoying defect that such a piece of apparatus can
+have&mdash;and various other improvements were made, as the necessity for them
+became apparent. They are described in detail farther below.</p>
+
+<p>The present appearance of the eye-end is shown in the illustration. The
+plate-holder is there shown, however, on one side of the tube, and its
+longer side is parallel to the axis of the telescope. This is not a good
+position for the eye-end, except for short exposures. In practice, the
+eye-end is always placed on the north or south side of the tube, according
+as the object photographed is north or south of the zenith. The right
+ascension slide is then always at right angles to the telescope axis, and
+the eye-end can not get into an inaccessible position during a long
+exposure.</p>
+
+<p>As the original wooden plate-holders were warped, and could not be
+depended upon to remain in the same position for several hours at a time,
+they were replaced by new ones of metal, and clamping screws were added,
+to hold them firmly in place. The heads of these screws are shown in the
+plate, between the springs which press the plate-holder against its bed.</p>
+
+<p>To illuminate the cross-wires of the guiding eyepiece, a small electric
+lamp is used, the current for which is brought down from the storage
+battery at the main<span class="pagenum"><a name="Page_22" id="Page_22">[Pg 22]</a></span> Observatory. The coarse wires have been replaced by
+spider&#8217;s webs,<small><a name="f9.1" id="f9.1" href="#f9">[9]</a></small> and reflectors have been introduced, to illuminate the
+declination thread. A collimating lens, placed at its principal focal
+distance from the incandescent filament of the lamp, makes the
+illumination of the wires nearly independent of their position on the
+slide, and a piece of red glass, close to the lens, effectually removes
+all danger of fogging the plate. The light is varied to suit the
+requirements of observation by rotating the reflector which throws the
+light in the direction of the eyepiece.</p>

+<p class="center">DOUBLE-SLIDE PLATE-HOLDER OF THE CROSSLEY REFLECTOR.</p>
+<p>&nbsp;</p>
+
+<p>In long exposures it is important for the observer to know at any moment
+the position of the plate with reference to its central or zero position.
+For this purpose scales with indexes are attached to both slides; but as
+they can not be seen in the dark, and, even if illuminated with red light,
+could not be read without removing the eye from the guiding eyepiece, I
+have added two short pins, one of<span class="pagenum"><a name="Page_23" id="Page_23">[Pg 23]</a></span> which is attached to the lower side of
+the right ascension slide, and the other to its guide, so that the points
+coincide when the scale reads zero. These pins can be felt by the fingers,
+and with a little practice the observer can tell very closely how far the
+plate is from its central position. It would not be a very difficult
+matter to improve on this contrivance, say by placing an illuminated
+scale, capable of independent adjustment, in the field of the eyepiece,
+but the pins answer every purpose. The declination slide is changed so
+little that no means for indicating its position are necessary.</p>
+
+<p>In this apparatus, as originally constructed, the cross-wires of the
+guiding eyepiece were exactly in the plane of the photographic plate. The
+earlier observations made with the Crossley reflector on Mount Hamilton
+showed that this is not the best position of the cross-wires. The image of
+a star in the guiding eyepiece, which, when in the middle of its slide, is
+nearly three inches from the axis of the mirror, is not round, and its
+shape varies as the eyepiece is pushed in or drawn out. In the plane of
+the photographic plate (assumed to be accurately in focus), it is a
+crescent, with the convex side directed toward the center of the plate.
+This form of image is not suitable for accurate guiding. Outside this
+position the image changes to an arrow-head, the point of which is
+directed toward the axis, and this image can be very accurately bisected
+by the right ascension thread. As the construction of the apparatus did
+not allow the plane of the cross-wires to be changed, the wooden bed of
+the plate-holder was cut down, so as to bring the wires and the plate into
+the proper relative positions.</p>
+
+<p>After some further experience with the instrument, still another change
+was made in this adjustment. It was found that the focus often changed
+very perceptibly during a long exposure, and while the arrow-head image
+above described was suitable for guiding purposes, its form was not
+greatly affected by changes of focus. Between the crescent and the
+arrow-head images there is a transition form, in which two well-defined
+caustic curves in the aberration pattern intersect at an acute angle. The
+intersection of these caustics offers an excellent mark for the
+cross-wires, and is at the same time very sensitive to changes of focus,
+which cause it to travel up or down in the general pattern. The bed of the
+plate-holder was therefore raised, by facing it with a brass plate of the
+proper thickness.</p>
+
+<p>Why the focus of the telescope should change during a long exposure is not
+quite clear. The change is much too great to be accounted for by expansion
+and contraction of the rods forming the tube, following changes of
+temperature, while a simple geometrical construction shows that a drooping
+of the upper end of the tube, increasing the distance of the plate from
+the (unreflected) axis of the mirror, can not displace the focus in a
+direction normal to the plate, if it is assumed that the field is flat.
+The observed effect is probably due to the fact that the focal surface is
+not flat, but curved. During a long exposure, the observer keeps the
+guiding star, and therefore, very approximately, all other stars, in the
+same <span class="pagenum"><a name="Page_24" id="Page_24">[Pg 24]</a></span>positions relatively to the plate; but he has no control over the
+position of the axis of the mirror, which, by changes of flexure, wanders
+irregularly over the field. The position of maximum curvature, therefore,
+also varies, and with it the focus of the guiding star relatively to the
+cross-wires, where the focal surface is considerably inclined to the field
+of view. It is certain that the focus does change considerably, whatever
+the cause may be, and that the best photographic star images are obtained
+by keeping the focus of the guiding star unchanged during the exposures.
+This is done by turning the focusing screw of the eye-end.</p>
+
+<p>In making the photographs of nebul&aelig; for which the Crossley telescope is at
+present regularly employed, it was at first our practice to adjust the
+driving-clock as accurately as possible to a sidereal rate, and then, when
+the star had drifted too far from its original position, on account of
+changes of rate or of flexure, to bring it back by the right-ascension
+slow motion, the observer either closing the slide of the plate-holder or
+following the motion of the star as best he could with the right-ascension
+screw. Lately a more satisfactory method, suggested by Mr. Palmer, has
+been employed. The slow motion in right ascension is of Grubb&#8217;s form,<small><a name="f10.1" id="f10.1" href="#f10">[10]</a></small>
+and the telescope has two slightly different rates, according to whether
+the loose wheel is stopped or allowed to turn freely. The driving-clock is
+adjusted so that one of these rates is too fast, the other too slow. At
+the beginning of an exposure the wheel is, say, unclamped, and the guiding
+star begins to drift very slowly toward the left, the observer following
+it with the screw of the plate-holder. When it has drifted far enough, as
+indicated by the pins mentioned farther above, the wheel is clamped. The
+star then reverses its motion and begins to drift toward the right; and so
+on throughout the exposure. The advantages of this method over the one
+previously employed are, that the star never has to be moved by the slow
+motion of the telescope, and that its general drift is in a known
+direction, so that its movements can be anticipated by the observer. In
+this way photographs are obtained, with four hours&#8217; exposure, on which the
+smallest star disks are almost perfectly round near the center of the
+plate, and from 2&Prime; to 3&Prime; in diameter.</p>
+
+<p>The star images are practically round over a field at least 1 inch or 16&prime;
+in diameter. Farther from the center they become parabolic, but they are
+quite good over the entire plate, 3&#188; by 4&#188; inches.</p>
+
+<p>From these statements it will be seen that small irregularities in driving
+no longer present any difficulties. But certain irregular motions of the
+image still take place occasionally, and so far it has not been possible
+entirely to prevent their occurrence.</p>
+
+<p>It was found that the declination clamp (the long slow-motion handle
+attached to which is shown in the illustration) was not sufficiently
+powerful to hold the telescope firmly during a long exposure. A screw
+clamp was therefore added, which<span class="pagenum"><a name="Page_25" id="Page_25">[Pg 25]</a></span> forces the toothed-declination sector
+strongly against an iron block just behind it, thus restoring, I think,
+the original arrangement of the declination clamp as designed by Dr.
+Common. This clamp holds the tube very firmly.</p>
+
+<p>The irregularities to which I have referred consist in sudden and
+unexpected jumps of the image, which always occur some time after the
+telescope has passed the meridian. These jumps are sometimes quite
+large&mdash;as much as one-sixteenth of an inch or 1. They are due to two
+causes: flexure of the tube, and sliding of the mirror on its bed. When
+the jump is due to sudden changes of flexure, the image moves very
+quickly, and vibrates before it comes to rest in its new position, and at
+the same time there is often heard a slight ringing sound from the tension
+rods of the tube. There seems to be no remedy for the sudden motions of
+this class. The tension rods are set up as tightly as possible without
+endangering the threads at their ends or buckling the large corner tubes.
+A round telescope tube, made of spirally-wound steel ribbon riveted at the
+crossings, would probably be better than the square tube now in use.</p>
+
+<p>Jumps due to shifting of the mirror are characterized by a gentle, gliding
+motion. They can be remedied, in part, at least, by tightening the copper
+bands which pass around the circumference of the mirror within its cell.
+This will be done the next time the mirror is resilvered.</p>
+
+<p>All that the observer can do when a jump occurs is to bring back the image
+as quickly as possible to the intersection of the cross-wires. If all the
+stars on the plate are faint, no effect will be produced on the
+photograph; but stars of the eighth magnitude or brighter will leave short
+trails. The nebula, if there is one on the plate, will, of course, be
+unaffected.</p>
+
+<p>Before beginning an exposure the focus is adjusted by means of a
+high-power positive eyepiece. An old negative, from which the film has
+been partially scraped, is placed in one of the plate-holders, and the
+film is brought into the common focus of the eyepiece and the great
+mirror. The appearance of the guiding star, which varies somewhat with the
+position of the guiding eyepiece on its slide, is then carefully noted,
+and is kept constant during the exposure by turning, when necessary, the
+focusing screw of the eye-end. For preliminary adjustments a ground-glass
+screen is often convenient. On it all the <i>DM.</i> stars, and even
+considerably fainter ones, as well as the nebul&aelig; of Herschel&#8217;s Class I,
+are easily visible without a lens.</p>
+
+<p>Plates are backed, not more than a day or two before use, with Carbutt&#8217;s
+&#8220;Columbian backing,&#8221; which is an excellent preparation for this purpose.
+During the exposure the observer and assistant exchange places every half
+hour, thereby greatly relieving the tediousness of the work, though two
+exposures of four hours each, in one night, have proved to be too
+fatiguing for general practice. At the end of the first two hours it is
+necessary to close the slide and wind the clock.</p>
+
+<p><span class="pagenum"><a name="Page_26" id="Page_26">[Pg 26]</a></span>The brightness of the guiding star is a matter of some importance. If the
+star is too bright, its glare is annoying; if it is too faint, the effort
+to see it strains the eye, and changes of focus are not easily recognized.
+A star of the ninth magnitude is about right. In most cases a suitable
+star can be found without difficulty.</p>
+
+<p>In such an apparatus as that described above, the amount by which the
+plate may be allowed to depart from its zero position is subject to a
+limitation which has not, I think, been pointed out, although it is
+sufficiently obvious when one&#8217;s attention has been called to it. It
+depends upon the fact that the plate necessarily moves as a whole, in a
+straight line which is tangent to a great circle of the sphere, while the
+stars move on small circles around the pole. The compensation for drift,
+when the plate is moved, is therefore exact at the equator only.</p>
+
+<p>Let the guiding star have the declination &#948;<sub>1</sub>, and let a
+star on the upper edge of the plate (which, when the telescope is north of
+the zenith, and the eye-end is on the north side of the telescope, will be
+the southern edge) have the declination &#948;<sub>2</sub>. Then if the
+guiding star is allowed to drift from its zero position through the
+distance <i>d</i>, the other star will drift through the distance <i>d</i> (cos
+&#948;<sub>2</sub> / cos &#948;<sub>1</sub>). If the guiding star is
+followed by turning the right-ascension screw, the upper edge of the
+plate, as well as the guiding eyepiece, will be moved through the distance
+<i>d</i>. Hence there will be produced an elongation of the upper star,
+represented by</p>
+

+
+<p>Now, in the Crossley reflector, the upper edge of the plate and the
+guiding eyepiece are just about 3&#8532; inches, or 1&deg;, apart. If <i>e</i> is
+given, the above formula serves to determine the maximum range of the
+slide for different positions of the telescope.</p>
+
+<p>It has been stated farther above that the smallest star disks, on a good
+photograph, are sometimes not more than 2&Prime; in diameter, or in a linear
+measure, about <span style="font-size: 0.8em;"><sup>1</sup></span>&frasl;<span style="font-size: 0.6em;">20</span> mm. An elongation of this amount is therefore
+perceptible. There are many nebul&aelig; in high northern declinations, and
+there are several particularly fine ones in about +70&deg;. If, therefore, we
+take &#948;<sub>2</sub> = 70&deg;, &#948;<sub>1</sub>, = 71&deg;, <i>e</i> = 0.05, and
+substitute these values, we find <i>d</i> = 1.0 mm, which is the greatest
+permissible range of the plate in photographing these nebul&aelig;. Before I
+realized the stringency of this requirement, by making the above simple
+computation, I spoiled several otherwise fine negatives by allowing the
+plate to get too far from the center, thus producing elongated star
+images.</p>
+
+<p>There is a corresponding elongation in declination, the amount of which
+can<span class="pagenum"><a name="Page_27" id="Page_27">[Pg 27]</a></span> be determined by an adaptation of the formula for reduction to the
+meridian, but it is practically insensible.</p>
+
+<p>On account of the short focal length of the three-foot mirror, the
+photographic resolving power of the telescope is much below its optical
+resolving power. For this reason the photographic images are less
+sensitive to conditions affecting the seeing than the visual images. On
+the finest nights the delicate tracery of bright lines or caustic curves
+in the guiding star is as clear and distinct as in a printed pattern. When
+the seeing is only fair these delicate details are lost, and only the
+general form of the image, with its two principal caustics, is seen. A
+photograph taken on such a night is not, however, perceptibly inferior to
+one taken when the seeing is perfect. When, however, the image is so
+blurred that its general form is barely distinguishable, the photographic
+star disks are likewise blurred and enlarged, and on such nights
+photographic work is not attempted.</p>
+
+<p>The foregoing account of the small changes which have been made in the
+Crossley telescope and its accessories may appear to be unnecessarily
+detailed, yet these small changes have greatly increased the practical
+efficiency of the instrument, and, therefore, small as they are, they are
+important. Particularly with an instrument of this character, the
+difference between poor and good results lies in the observance of just
+such small details as I have described.</p>
+
+<p>At present the Crossley reflector is being used for photographing nebul&aelig;,
+for which purpose it is very effective. Some nebul&aelig; and clusters, like the
+great nebula in <i>Andromeda</i> and the <i>Pleiades</i>, are too large for its
+plate (3&#188; &times; 4&#188; in.), but the great majority of nebul&aelig; are very much
+smaller, having a length of only a few minutes of arc, and a large-scale
+photograph is required to show them satisfactorily. It is particularly
+important to have the images of the involved stars as small as they can be
+made.</p>
+
+<p>Many nebul&aelig; of Herschel&#8217;s I and II classes are so bright that fairly good
+photographs can be obtained with exposures of from one to two hours; but
+the results obtained with full-light action are so superior to these, that
+longer exposures of three and one half or four hours are always preferred.
+In some exceptional cases, exposures of only a few minutes are sufficient.
+The amount of detail shown, even in the case of very small nebul&aelig;, is
+surprising. It is an interesting fact that these photographs confirm (in
+some cases for the first time) many of the visual observations made with
+the six-foot reflector of the Earl of Rosse.</p>
+
+<p>Incidentally, in making these photographs, great numbers of new nebul&aelig;
+have been discovered. The largest number that I have found on any one
+plate is thirty-one. Eight or ten is not an uncommon number, and few
+photographs have been obtained which do not reveal the existence of three
+or four. A catalogue of these new objects will be published in due time.</p>
+
+<p>Some of the results obtained with the Crossley reflector, relating chiefly
+to<span class="pagenum"><a name="Page_28" id="Page_28">[Pg 28]</a></span> particular objects of some special interest, have already been
+published.<small><a name="f11.1" id="f11.1" href="#f11">[11]</a></small> The photographs have also permitted some wider conclusions
+to be drawn, which are constantly receiving further confirmation as the
+work progresses. They may be briefly summarized as follows:</p>
+
+<p>1. Many thousands of unrecorded nebul&aelig; exist in the sky. A conservative
+estimate places the number within reach of the Crossley reflector at about
+120,000. The number of nebul&aelig; in our catalogues is but a small fraction of
+this.</p>
+
+<p>2. These nebul&aelig; exhibit all gradations of apparent size, from the great
+nebula in <i>Andromeda</i> down to an object which is hardly distinguishable
+from a faint star disk.</p>
+
+<p>3. Most of these nebul&aelig; have a spiral structure.</p>
+
+<p>To these conclusions I may add another, of more restricted significance,
+though the evidence in favor of it is not yet complete. Among the objects
+which have been photographed with the Crossley telescope are most of the
+&#8220;double&#8221; nebul&aelig; figured in Sir John Herschel&#8217;s catalogue (<i>Phil. Trans.</i>,
+1833, Plate XV). The actual nebul&aelig;, as photographed, have almost no
+resemblance to the figures. They are, in fact, spirals, sometimes of very
+beautiful and complex structure; and, in any one of the nebul&aelig;, the
+secondary nucleus of Herschel&#8217;s figure is either a part of the spiral
+approaching the main nucleus in brightness, or it can not be identified
+with any real part of the object. The significance of this somewhat
+destructive conclusion lies in the fact that these figures of Herschel
+have sometimes been regarded as furnishing analogies for the figures which
+Poincar&eacute; had deduced, from theoretical considerations, as being among the
+possible forms assumed by a rotating fluid mass; in other words, they have
+been regarded as illustrating an early stage in the development of double
+star systems. The actual conditions of motion in these particular nebul&aelig;,
+as indicated by the photographs, are obviously very much more complicated
+than those considered in the theoretical discussion.</p>
+
+<p><span class="pagenum"><a name="Page_29" id="Page_29">[Pg 29]</a></span>While I must leave to others an estimate of the importance of these
+conclusions, it seems to me that they have a very direct bearing on many,
+if not all, questions concerning the cosmogony. If, for example, the
+spiral is the form normally assumed by a contracting nebulous mass, the
+idea at once suggests itself that the solar system has been evolved from a
+spiral nebula, while the photographs show that the spiral nebula is not,
+as a rule, characterized by the simplicity attributed to the contracting
+mass in the nebular hypothesis. This is a question which has already been
+taken up by Professor Chamberlin and Mr. Moulton of the University of
+Chicago.</p>
+
+<p>The Crossley reflector promises to be useful in a number of fields which
+are fairly well defined. It is clearly unsuitable for photographing the
+Moon and planets, and for star charting. On the other hand, it has proved
+to be of value for finding and photographically observing asteroids whose
+positions are already approximately known.</p>
+
+<p>One of the most fruitful fields for this instrument is undoubtedly stellar
+spectroscopy. Little has been done in this field, as yet, with the
+Crossley reflector, but two spectrographs, with which systematic
+investigations will be made, have nearly been completed by the Observatory
+instrument-maker. One of these, constructed with the aid of a fund given
+by the late Miss C. W. Bruce, has a train of three 60&deg; prisms and one 30&deg;
+prism, and an aperture of two inches; the other, which has a single quartz
+prism, will, I have reason to expect, give measurable, though small,
+spectra of stars nearly at the limit of vision of the telescope.</p>
+
+<p>The photogravure<small><a name="f12.1" id="f12.1" href="#f12">[12]</a></small> of the Trifid nebula, which accompanies this article,
+was made from a photograph taken with the Crossley reflector on July 6,
+1899, with an exposure of three hours. It was not selected as a specimen
+of the work of the instrument, for the negative was made in the early
+stages of the experiments that I have described, and the star images are
+not good, but rather on account of the interest of the subject. At the
+time the photogravures were ordered no large scale photograph of the
+Trifid nebula had, so far as I am aware, ever been published.<small><a name="f13.1" id="f13.1" href="#f13">[13]</a></small> The
+remarkable branching structure of the nebula is fairly well shown in the
+photogravure, though less distinctly than in the transparency from which
+it was made. The enlargement, as compared with the original negative, is
+2.9 diameters (1 mm = 13&Prime;). The fainter parts of the nebula would be
+shown more satisfactorily by a longer exposure.</p>

+written, seem to have had their origin in the fact that it was impossible,
+at the time of the preliminary trials, to provide the observer with an
+assistant, while the Crossley reflector is practically unmanageable by a
+single person.</p>

+unnecessary when red light is used.</p>

+<p><a name="f9" id="f9" href="#f9.1">[9]</a> It so happens that the tension of the vertical thread is such that it
+begins to slacken when the temperature falls to within about 2&deg; of the dew
+point. The thread thus forms an excellent hygrometer, which is constantly
+under the eye of the observer. When the thread becomes slack, it is time

+
+1.E.  Unless you have removed all references to Project Gutenberg:
+
+1.E.1.  The following sentence, with active links to, or other immediate

+
+1.E.2.  If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges.  If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1

+permission of the copyright holder found at the beginning of this work.
+
+1.E.4.  Do not unlink or detach or remove the full Project Gutenberg-tm
+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.
+
+1.E.5.  Do not copy, display, perform, distribute or redistribute this
+electronic work, or any part of this electronic work, without
+prominently displaying the sentence set forth in paragraph 1.E.1 with
+active links or immediate access to the full terms of the Project
+Gutenberg-tm License.
+
+1.E.6.  You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form.  However, if you provide access to or
+distribute copies of a Project Gutenberg-tm work in a format other than
+"Plain Vanilla ASCII" or other format used in the official version
+posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
+you must, at no additional cost, fee or expense to the user, provide a
+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original "Plain Vanilla ASCII" or other
+form.  Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.
+
+1.E.7.  Do not charge a fee for access to, viewing, displaying,

+1.E.8.  You may charge a reasonable fee for copies of or providing
+access to or distributing Project Gutenberg-tm electronic works provided
+that
+
+- You pay a royalty fee of 20% of the gross profits you derive from
+     the use of Project Gutenberg-tm works calculated using the method
+     you already use to calculate your applicable taxes.  The fee is
+     owed to the owner of the Project Gutenberg-tm trademark, but he
+     has agreed to donate royalties under this paragraph to the
+     Project Gutenberg Literary Archive Foundation.  Royalty payments
+     must be paid within 60 days following each date on which you
+     prepare (or are legally required to prepare) your periodic tax
+     returns.  Royalty payments should be clearly marked as such and
+     sent to the Project Gutenberg Literary Archive Foundation at the
+     address specified in Section 4, "Information about donations to
+     the Project Gutenberg Literary Archive Foundation."
+
+- You provide a full refund of any money paid by a user who notifies
+     you in writing (or by e-mail) within 30 days of receipt that s/he
+     does not agree to the terms of the full Project Gutenberg-tm
+     License.  You must require such a user to return or
+     destroy all copies of the works possessed in a physical medium
+     and discontinue all use of and all access to other copies of
+     Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+     money paid for a work or a replacement copy, if a defect in the
+     electronic work is discovered and reported to you within 90 days
+     of receipt of the work.
+
+- You comply with all other terms of this agreement for free
+     distribution of Project Gutenberg-tm works.
+
+1.E.9.  If you wish to charge a fee or distribute a Project Gutenberg-tm
+electronic work or group of works on different terms than are set
+forth in this agreement, you must obtain permission in writing from
+both the Project Gutenberg Literary Archive Foundation and Michael
+Hart, the owner of the Project Gutenberg-tm trademark.  Contact the
+Foundation as set forth in Section 3 below.
+
+1.F.
+
+1.F.1.  Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection.  Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2.  LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees.  YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3.  LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a
+written explanation to the person you received the work from.  If you
+received the work on a physical medium, you must return the medium with
+your written explanation.  The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund.  If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund.  If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4.  Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
+WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
+
+1.F.5.  Some states do not allow disclaimers of certain implied

+1.F.6.  INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,
+promotion and distribution of Project Gutenberg-tm electronic works,
+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+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.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3.  Information about the Project Gutenberg Literary Archive
+Foundation

+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service.  The Foundation's EIN or federal tax identification
+number is 64-6221541.  Its 501(c)(3) letter is posted at

+
+
+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 http://pglaf.org
+
+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.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5.  General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone.  For thirty 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:
+
+     http://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.

+NOTE.
+
+
+In the original negatives of subjects 10 and 12, there are faint dark
+rings immediately surrounding some of the stars in the denser parts of the
+nebulosity. This effect has no doubt been accentuated in the subsequent
+photographic processes. On the plates of these two subjects in the
+completed volume, these rings are very distinct and give rise to a
+suspicion that the effect has been enhanced by the engraver. A critical
+examination of the prints seems to confirm this view. In the original
+proofs these rings were inconspicuous and were not noticed. The processes
+of steel-facing and printing appear to have increased the effect markedly,
+as it is much stronger on the sheets printed for the edition than in any
+of the early proofs.
+
+Inasmuch as these effects were not and could not be discovered until the
+sheets were assembled in Sacramento for binding, it has not been thought
+desirable to delay the issue of the volume for several weeks additional in
+order to have new plates and new prints of these subjects made by the
+distant engraver.

+
+PREFACE.
+
+
+When Professor Keeler entered upon the duties of Director of the Lick
+Observatory, on June 1, 1898, he planned to devote his observing time for
+several years to photographing the brighter nebulae and star clusters, with
+the Crossley reflector. The story of his wonderful success with this
+difficult instrument is familiar to all readers of astronomical
+literature: this form of telescope was in effect born again; and his
+contributions to our knowledge of the nebulae were epoch-making.
+
+Professor Keeler's observing programme included one hundred and four
+subjects. At the time of his lamented death, on August 12, 1900,
+satisfactory negatives of two-thirds of the selected objects had been
+secured. The unphotographed objects were mainly those which come into
+observing position in the unfavorable winter and spring months. The
+completion of the programme was entrusted to Assistant Astronomer Perrine.
+The observers were assisted chiefly by Mr. H. K. Palmer, and in smaller
+degree by Messrs. Joel Stebbins, C. G. Dall, R. H. Curtiss and Sebastian
+Albrecht.
+
+Professor Keeler's photographs enabled him to make two discoveries of
+prime importance, not to mention several that are scarcely secondary to
+them.
+
+1st.--"Many thousands of unrecorded nebulae exist in the sky. A
+conservative estimate places the number within reach of the Crossley
+reflector at about 120,000. The number of nebulae in our catalogues is but
+a small fraction of this." [The number already discovered and catalogued
+did not exceed 13,000. Later observations with the Crossley reflector,
+with longer exposure-times and more sensitive plates, render it probable
+that the number of nebulae discoverable with this powerful instrument is of
+the order of half a million.]
+
+2d.--"Most of these nebulae have a spiral structure."
+
+The photographs of the one hundred and four subjects contain the images of
+744 nebulae not previously observed. A catalogue of these is published in
+the present volume. Their positions, which are thought to be accurate
+within 1'', were determined by Messrs. Palmer, Curtiss, and Albrecht.
+
+The main purpose of this volume is to reproduce and make available for
+study, the larger and more interesting nebulae and clusters on the
+programme, sixty-eight in number. The thirty-six subjects not reproduced
+are for the most part small or apparently not of special interest. The
+difficulties attending the reproduction of astronomical photographs by
+mechanical processes are well-known to all who have made the attempt. It
+seems necessary to recognize, at least at present, that delicate details
+of structure will be lost, and that contrasts between very bright and very
+faint regions will be changed, especially if a good sky background is
+preserved; in other words, that the best obtainable reproductions fall far
+short of doing justice to the original photographs. Technical studies
+should be based upon the original negatives or upon copies on glass.
+
+After considerable experimental work, involving several methods and
+several firms, the making of the heliogravure plates and the hand-press
+prints was entrusted to The Photogravure and Color Company of New York
+City. To this firm's continued interest and willingness to act on
+constructive criticism is due much of the excellence of the results.
+
+The expensive reproductions could hardly have been undertaken without the
+generous assistance of the donors mentioned on a preceding page.
+
+Professor Keeler's description of the Crossley reflector, of his methods
+of observing, and of the chief results obtained, was written only a short
+time before his death. It is here republished. Other results of his work
+are described in the several papers to which the footnotes refer.

+THE CROSSLEY REFLECTOR OF THE LICK OBSERVATORY.[1]
+
+By JAMES E. KEELER.
+
+
+The Crossley reflector, at present the largest instrument of its class in
+America, was made in 1879 by Dr. A. A. Common, of London, in order to
+carry out, and test by practical observation, certain ideas of his
+respecting the design of large reflecting telescopes. For the construction
+of the instrument embodying these ideas, and for some fine astronomical
+photographs obtained with it, Dr. Common was awarded the gold medal of the
+Royal Astronomical Society in 1884.
+
+In 1885, Dr. Common, wishing to make a larger telescope on a somewhat
+similar plan, sold the instrument to Edward Crossley, Esq., F. R. A. S.,
+of Halifax, England. Mr. Crossley provided the telescope with a dome of
+the usual form, in place of the sliding roof used by its former owner, and
+made observations with it for some years; but the climate of Halifax not
+being suitable for the best use of such a telescope, he consented, at the
+request of Dr. Holden, then Director of the Lick Observatory, to present
+it to this institution. The funds for transporting the telescope and dome
+to California, and setting them up on Mount Hamilton, were subscribed by
+friends of the Lick Observatory, for the most part citizens of California.
+The work was completed, and the telescope housed in a suitable observatory
+building, in 1895.[2]
+
+On taking charge of the Lick Observatory in 1898, I decided to devote my
+own observing time to the Crossley reflector, although the whole of my
+previous experience had been with refracting telescopes. I was more
+particularly desirous of testing the reflector with my own hands, because
+such preliminary trials of it as had been made had given rise to somewhat
+conflicting opinions as to its merits.[3] The result of my experience is
+given in the following article, which is written chiefly with reference to
+American readers. If I have taken occasion to point out what I regard as
+defects in the design or construction of the instrument, I have done so,
+not from any desire to look a gift horse in the mouth, but in the interest
+of future improvement, and to make intelligible the circumstances under
+which the work of the reflector is now being done and will be done
+hereafter. The most important improvements which have suggested themselves
+have indeed already been made by Dr. Common himself, in constructing his
+five-foot telescope. The three-foot reflector is, in spite of numerous
+idiosyncracies which make its management very different from the
+comparatively simple manipulation of a refractor, by far the most
+effective instrument in the Observatory for certain classes of
+astronomical work. Certainly no one has more reason than I to appreciate
+the great value of Mr. Crossley's generous gift.
+
+
+[Illustration: DOME OF THE CROSSLEY REFLECTOR.]
+
+
+The Crossley dome is about 350 yards from the main Observatory, at the end
+of a long rocky spur which extends from the Observatory summit toward the
+south, and on which are two of the houses occupied by members of the
+Observatory staff. It is below the level of the lowest reservoir,
+"Huyghens," which receives the discharge from the hydraulic machinery of
+the 36-inch refractor, and therefore the water engine furnished by Mr.
+Crossley for turning the dome can not be used, unless a new water
+system--overflow reservoir, pump and windmill--is provided. In this
+respect a better site would have been a point on the south slope of
+"Kepler,"--the middle peak of Mount Hamilton--just above the Huyghens
+reservoir. No addition to the present water system would then have been
+needed. The slope of the mountain at this place might cut off the view of
+the north horizon, but since the telescope can not be turned below the
+pole, this would be a matter of no consequence. Water-power for the dome
+is not, however, really necessary.
+
+The cylindrical walls of the dome, 36-1/4 feet inside diameter, are
+double, and provided with ventilators. Opening into the dome, on the left
+of the entrance, are three small rooms, one of which has been fitted up as
+a photographic dark room, and another, containing a sidereal clock and a
+telephone, which communicates with the main Observatory, as a study, while
+the third is used for tools and storage. There is also a small room for
+the water engine, in case it should be used. The dome is at present
+supplied with water from only the middle reservoir, Kepler, which is
+reserved for domestic purposes and is not allowed to pass through the
+machinery.
+
+The dome itself, 38 feet 9 inches in diameter, is made of sheet-iron
+plates riveted to iron girders. It also carries the wooden gallery,
+ladders, and observing platform, which are suspended from it by iron rods.
+The apparatus for turning the dome consists of a cast-iron circular rack
+bolted to the lower side of the sole-plate, and a set of gears terminating
+in a sprocket-wheel, from which hangs an endless rope. As the dome does
+not turn easily, it has been necessary to multiply the gearing of the
+mechanism so that one arm's-length pull on the rope moves the dome only
+about one inch. In some positions of the telescope the dome can not be
+moved more than six or eight inches at a time without danger of striking
+the tube, and this slowness of motion is then not disadvantageous. It is
+only when the dome has to be moved through a considerable angle, as in
+turning to a fresh object, or in photographing some object which passes
+nearly through the zenith, that the need for a mechanical means of
+rotation is felt.
+
+The observing slit, 6 feet wide, extends considerably beyond the zenith.
+It is closed by a double shutter, which is operated by an endless rope.
+The upper part, within the dome, is also closed by a hood, or shield,
+which serves to protect the telescope from any water that may find its way
+through the shutter, and which is rolled back to the north when
+observations are made near the zenith. I have recently fitted the lower
+half of the slit with a wind-screen, which has proved to be a most useful
+addition. It is made of tarpaulin, attached to slats which slide between
+the two main girders, and is raised or lowered by halliards, which belay
+to cleats on the north rail of the gallery. A more detailed description of
+the dome has been given in an article by Mr. Crossley,[4] from which the
+reduced figure in Fig. 1[5] has been taken.
+
+The mounting of the three-foot reflector has been very completely
+described and illustrated by Dr. Common,[6] so that only a very general
+description need be given here. The most important feature of the
+mounting is that the telescope tube, instead of being on one side of the
+polar axis, as in the usual construction, is central, so that the axis of
+the mirror and the polar axis are in the same line when the telescope is
+directed to the pole. The declination axis is short, and is supported by a
+massive goose-neck bolted to the upper end of the polar axis. The mirror
+is placed just _above_ the declination axis. Its weight, and the weight of
+the whole tube and eye-end, are counterpoised by slabs of lead, placed in
+two iron boxes, between which the goose-neck of the polar axis passes. The
+great advantage of this arrangement, and the controlling principle of the
+design, is that the telescope is perfectly free to pass the meridian at
+all zenith distances. No reversal of the instrument is needed, or is
+indeed possible.
+
+
+[Illustration: THE CROSSLEY REFLECTOR.]
+
+
+For long-exposure photography, the advantage above referred to is obvious,
+but it is attended by certain disadvantages. One of these is that a very
+much larger dome is required than for the usual form of mounting. Another
+is the great amount of dead weight which the axes must carry; for the
+mirror, instead of helping to counterpoise the upper end of the tube, must
+itself be counterpoised. When anything is attached to the eye-end (and in
+astrophysical work one is always attaching things to the eye-end of a
+telescope), from ten to twenty times as much weight must be placed in the
+counterpoise boxes below the declination axis. Where room is to be found
+for the weights required to counterpoise the Bruce spectrograph, is a
+problem which I have not yet succeeded in solving.
+
+In his five-foot reflector, Dr. Common has caused the telescope tube to
+swing between two large ears, which project from the upper end of the
+boiler-like polar axis, the pivots constituting the declination axis being
+near, but above, the lower end of the tube. The mirror, therefore, helps
+to counterpoise the upper end of the tube. This I regard as a distinct
+improvement. The danger of large masses of metal near the mirror injuring
+the definition is, in my opinion, imaginary; at least there is no such
+danger on Mount Hamilton, where the temperature variations are unusually
+small. Experience with the Crossley reflector, as well as with the other
+instruments of the Lick Observatory, shows that the definition depends
+almost entirely on external conditions.
+
+My first trials of the reflector, as first mounted at the Lick
+Observatory, showed that the center of motion was inconveniently high.
+Among other difficulties arising from this circumstance, the spectroscope
+projected beyond the top of the dome, so that it had to be removed before
+the shutter could be closed. In July, 1898, the pier was therefore cut
+down two feet. This brought the eye-end down nearly to the level of the
+gallery rail, where it was at a convenient height for the observer when
+sitting on a camp-stool, and it made all parts of the mounting more
+accessible. Toward the north and south, the range of the telescope, being
+limited in these directions by the construction of the mounting, was not
+affected by the change, but the telescope can not now be used at such low
+altitudes as formerly, near the east and west points of the horizon. The
+only occasion likely to call for the use of the reflector in these
+positions is the appearance of a large comet near the Sun, and, after some
+consideration, I decided to sacrifice these chances for the sake of
+increasing the general usefulness of the instrument. Except in rare cases,
+all observations are made within three hours of the meridian.
+
+To adapt the mounting to the latitude of Mount Hamilton, a wedge-shaped
+casting, shown in the illustration, had been provided, but through some
+error, arising probably from the fact that the telescope had been used in
+two different latitudes in England, the angle of the casting was too
+great. When the pier was cut down its upper surface was therefore sloped
+toward the south, in order to compensate the error in the casting. Plate
+VII shows the instrument very nearly as it is at the present time.
+
+The polar axis of the Crossley reflector is a long, hollow cylinder,
+separated by a space of about one-eighth of an inch from its concentric
+casing. The idea was to fill this space with mercury, and float the
+greater part of the thrust of the axis, the function of a small steel pin
+at the lower end being merely to steady the axis. But this mercury
+flotation, as applied to the Crossley telescope, is a delusion, as I think
+Mr. Crossley had already found. The mercury, it is true, relieves the
+thrust to some extent, but it greatly increases the already enormous side
+pressure on the steel pin at the bottom, thus creating a much greater evil
+than the one it is intended to remedy. The workmen who set up the mounting
+inform me that the small bearing at the lower end of the polar axis is
+badly worn, as I should expect it to be. Instead of putting mercury into
+the space intended for it, I have therefore poured in a pint or so of oil,
+to keep the lower bearing lubricated. For the reasons indicated above, the
+force required to move the telescope in right ascension is perhaps five
+times greater than it should be. The lower end of the polar axis ought to
+be fitted with ball bearings to take the thrust, and with a pair of
+friction wheels on top; but it would be difficult to make these changes
+now. It should be observed that the disadvantages of the mercury flotation
+are considerably greater at Mount Hamilton than at the latitude for which
+the telescope was designed.
+
+
+[Illustration: THE CROSSLEY REFLECTOR.]
+
+
+As already stated above, the range of the telescope is limited on the
+south by the construction of the mounting. The greatest southern
+declination which can be observed is 25 deg.. In England this would doubtless
+mark the limit set by atmospheric conditions, but at Mount Hamilton it
+would be easy to photograph objects 15 deg. farther south, if the telescope
+could be pointed to them.
+
+The original driving-clock having proved to be inefficient, at least
+without an electric control, a new and powerful driving-clock was made by
+the Observatory instrument maker, from designs by Professor Hussey. In its
+general plan it is like that of the 36-inch refractor. The winding
+apparatus, contained in the large casting of the original mounting, has no
+maintaining power, and can not easily be fitted with one. The clock could
+in no case be wound during a photographic exposure, on account of the
+tremors attending the operation, but it would be somewhat more convenient
+to have the stars remain on the plate during the winding. With a little
+practice, however, one can wind the clock without actually stopping it,
+though the object must afterwards be brought back to its place by means of
+the slow motion in right ascension.
+
+Two finders have recently been fitted to the Crossley reflector. One has
+an object-glass of four inches aperture and eight feet six inches focal
+length, with a field of about 1 deg. 2', which is very nearly the photographic
+field of the main telescope. Its standards are bolted to one of the corner
+tubes of the reflector. The other finder has a three-inch objective and a
+large field. It had not been mounted when the photograph for the plate was
+made.
+
+When a telescope is used for photographing objects near the pole, with
+long exposures, the polar axis must be quite accurately adjusted, for
+otherwise the centers of motion of the stars and of the telescope will not
+agree, and the star images will be distorted. It is true that with a
+double-slide plate-holder, like the one used with the Crossley reflector,
+one star--namely, the guiding star--is forced to remain in a fixed
+position with respect to the plate; but the differential motion of the
+other stars causes them to describe short arcs, or trails, around this
+star as a center. A considerable part of the spring of 1899 was spent in
+efforts to perfect the adjustment of the polar axis, an operation which,
+on account of the peculiar form of the mounting, offers unusual
+difficulties.
+
+In the first plan which was tried, the reflector was used as a transit
+instrument. The inclination of the declination axis was determined with a
+hanging level which had been provided by Mr. Crossley, the hour circle and
+polar axis being very firmly clamped. The clock correction being known
+from the records kept at the Observatory, the collimation and azimuth
+constants were found by the usual formulae. This method failed to give
+satisfactory results, and it was found later that the declination and
+polar axis were not exactly at right angles.
+
+There is only one part of the sky on which the telescope can be reversed;
+namely, the pole. A method which promised well, and on which some time was
+spent, consists in photographing the pole (the declination axis being
+horizontal) by allowing the stars near it to trail for ten or fifteen
+minutes, then turning the polar axis 180 deg. and photographing the pole again
+on the same plate. Half the distance between the images gives the error of
+the polar axis, which, if the plate is properly oriented, is easily
+resolved into horizontal and vertical components; while the distance of
+each image from the center of the plate is this error increased or
+diminished by twice the deviation of the telescope axis. In this case the
+vertical component depends upon the reading of the declination circle, and
+the horizontal component gives the error of collimation. This method
+failed, however, to give consistent results, mainly on account of
+instability of the mirror, and was abandoned.
+
+The use of the large mirror for purposes of adjustment was finally given
+up, and the axis was adjusted by observations of _Polaris_ with the long
+finder, in the usual manner. In order to reach the star at lower
+culmination the finder tube had to be thrown out of parallelism with the
+main telescope.
+
+The base-plate having no definite center of rotation in azimuth, and the
+wedges and crowbars used for moving it being uncertain in their action, a
+watch telescope, provided with a micrometer eyepiece, was firmly secured
+to the mounting throughout these operations, in such manner that a mark on
+the southern horizon could be observed through one of the windows of the
+dome. The errors of the polar axis were finally reduced to within the
+limits of error of observation.
+
+The movable hour circle and driving wheel of the Crossley reflector has
+two sets of graduations. The driving screw having been thrown out of gear,
+the circle is turned until the outer vernier indicates the sidereal time,
+whereupon the driving screw is thrown into gear again. The inner vernier
+is then set to the right ascension of the object which it is desired to
+observe. As an inconsistency, of minor importance, in the design of the
+mounting, I may note that the slow motion in right ascension changes the
+reading of the outer vernier instead of that of the inner one. In
+practice, however, no inconvenience is caused by this construction.
+
+In the early experiments and photographic work with the Crossley
+telescope, irregularities in driving were a source of great annoyance. Dr.
+Roberts, in laying down the conditions which should be fulfilled by a good
+photographic telescope, says that a star should remain bisected by a
+thread in the eyepiece for two minutes at a time. The Crossley telescope
+was so far from fulfilling this condition that a star would not keep its
+place for two consecutive seconds; and the greatest alertness on the part
+of the observer did not suffice to ensure round star images on a
+photographic plate. It was obvious that the fault did not lie with the
+driving clock; in fact, many of the sudden jumps in right ascension, if
+explained in this way, would have required the clock to run backward;
+nevertheless the clock was tested by causing its revolutions to be
+recorded on a chronograph at the main Observatory, together with the beats
+of one of the standard clocks. For this purpose a break-circuit attachment
+was made by Mr. Palmer. The errors of the clock were in this way found to
+be quite small.
+
+The principal source of the irregularities was found in the concealed
+upper differential wheel of the Grubb slow motion. This wheel turned with
+uncertain friction, sometimes rotating on its axis, and sometimes
+remaining at rest. After it was checked the driving was much better, and
+was still farther improved by repairing some defective parts of the train.
+Small irregularities still remain. They seem to be partly due to
+inaccuracies in the cutting of the gears, or of the teeth of the large
+driving wheel, and partly to the springing of the various parts, due to
+the very considerable friction of the polar axis in its bearings. The
+remaining irregularities are so small, however, that they are easily
+corrected by the screws of the sliding plate-holder, and with reasonable
+attention on the part of the observer, round star images are obtained with
+exposures of four hours' duration.
+
+The large mirror, the most important part of the telescope, has an
+aperture of three feet, and a focal length of 17 feet 6.1 inches. It was
+made by Mr. Calver. Its figure is excellent. On cutting off the cone of
+rays from a star, by a knife-edge at the focus, according to the method of
+Foucault, the illumination of the mirror is very uniform, while the star
+disks as seen in an ordinary eyepiece are small and almost perfectly
+round. They are not, I think, quite so good as the images seen with a
+large refractor; still, they are very good indeed, as the following
+observations of double stars, made recently for this purpose, will show.
+
+Several close double stars were examined on the night of April 17, 1900,
+with a power of 620. The seeing was four on a scale of five. The
+magnitudes and distances of the components, as given in the table, are
+from recent observations by Professor Hussey with the 36-inch refractor.

+
+Although the theoretical limit of resolution for a three-foot aperture is
+not reached in these observations, I do not think the mirror can do any
+better.
+
+The small mirror, or flat, at the upper end of the tube, is circular, the
+diameter being nine inches. Its projection on the plane of the
+photographic plate is therefore elliptical; but the projection of the
+mirror and its cell on the plane of the great mirror is very nearly
+circular.
+
+The small mirror, acting as a central stop, has the effect of diminishing
+the size of the central disk of the diffraction pattern, at the expense of
+an increase in the brightness of the system of rings. To this effect may
+be due, in part, the inferiority of the reflector for resolving bright
+doubles, as compared with a refractor of the same aperture. For
+photographic purposes, it is evident that the mirror is practically
+perfect.
+
+The upper end of the tube can be rotated, carrying with it the flat and
+the eye-end. Whenever the position is changed, the mirrors have to be
+re-collimated. In practice it is seldom necessary to touch the adjusting
+screws of the mirrors themselves. The adjustment is effected by means of
+clamping and butting screws on the eye-end, and a change of the line of
+collimation, with respect to the finders and the circles, is avoided. The
+operation is generally referred to, however, as an adjustment of the
+mirrors.
+
+For adjusting the mirrors there are two collimators. One of these is of
+the form devised by Mr. Crossley.[7] It is very convenient in use, and is
+sufficiently accurate for the adjustment of the eye-end when the telescope
+is used for photographic purposes, inasmuch as the exact place where the
+axis of the large mirror cuts the photographic plate is not then a matter
+of great importance, so long as it is near the center. Moreover, as stated
+farther below, the direction of the axis changes during a long exposure.
+The other collimator is of a form originally due, I think, to Dr.
+Johnstone Stoney. It consists of a small telescope, which fits the
+draw-tube at the eye-end. In the focus of the eyepiece are, instead of
+cross-wires, two adjustable terminals, between which an electric spark can
+be passed, generated by a small induction machine, like a replenisher,
+held in the observer's hand. The terminals are at such a distance inside
+the principal focus of the objective, that the light from the spark, after
+reflection from the flat, appears to proceed from the center of curvature
+of the large mirror. The rays are therefore reflected back normally, and
+form an image of the spark which, when the mirrors are in perfect
+adjustment, coincides with the spark itself. The precision of this method
+is very great. It is in fact out of proportion to the degree of refinement
+attained in other adjustments of the reflector, for a slight pressure of
+the hand on the draw-tube, or movement of the telescope to a different
+altitude, instantly destroys the perfection of the adjustment. I have
+provided these collimators with an adapter which fits the photographic
+apparatus, so that one can adjust the mirrors without having to remove
+this apparatus and substitute for it the ordinary eye-end carrying the
+eyepieces.
+
+For visual observation the Crossley telescope is provided with seven
+eyepieces, with powers ranging from 620 downward. The lowest power is only
+60, and consequently utilizes only 12 inches of the mirror, 9 of which are
+covered by the central flat. It is therefore of little value, except for
+finding purposes. The next lowest power utilizes 28 inches of the mirror.
+The other eyepieces call for no remark.
+
+But, while the Crossley reflector would doubtless be serviceable for
+various kinds of visual observations, its photographic applications are
+regarded as having the most importance, and have been chiefly considered
+in deciding upon the different changes and improvements which have been
+made.
+
+The interior of the dome is lighted at night by a large lamp, which is
+enclosed in a suitable box or lantern, fitted with panes of red glass, and
+mounted on a portable stand. In order to diffuse the light in the lower
+part of the dome, where most of the assistant's work is done, the walls
+are painted bright red; while to prevent reflected light from reaching the
+photographic plate, the inner surface of the dome itself, the mounting,
+and the ladders and gallery are painted dead black. The observer is
+therefore in comparative darkness, and not the slightest fogging of the
+plate, from the red light below, is produced during a four-hours'
+exposure. On the few occasions when orthochromatic plates are used the
+lamp need not be lighted.
+
+Experiments have shown that the fogging of the photographic plate, during
+a long exposure, is entirely due to diffuse light from the sky, and is
+therefore unavoidable. For this reason the cloth curtains which lace to
+the corners of the telescope tube, enclosing it and shutting out light
+from the lower part of the dome, have not been used, since their only
+effect would be to catch the wind and cause vibrations of the telescope.
+They would probably have little effect on the definition, and at any rate
+could not be expected to improve it.
+
+For photographing stars and nebulae the Crossley reflector is provided with
+a double-slide plate-holder, of the form invented by Dr. Common.[8] This
+apparatus, which had suffered considerably in transportation, and from
+general wear and tear, was thoroughly overhauled by the Observatory
+instrument-maker. The plates were straightened and the slides refitted. A
+spring was introduced to oppose the right ascension screw and take up the
+lost motion--the most annoying defect that such a piece of apparatus can
+have--and various other improvements were made, as the necessity for them
+became apparent. They are described in detail farther below.
+
+The present appearance of the eye-end is shown in the illustration. The
+plate-holder is there shown, however, on one side of the tube, and its
+longer side is parallel to the axis of the telescope. This is not a good
+position for the eye-end, except for short exposures. In practice, the
+eye-end is always placed on the north or south side of the tube, according
+as the object photographed is north or south of the zenith. The right
+ascension slide is then always at right angles to the telescope axis, and
+the eye-end can not get into an inaccessible position during a long
+exposure.
+
+As the original wooden plate-holders were warped, and could not be
+depended upon to remain in the same position for several hours at a time,
+they were replaced by new ones of metal, and clamping screws were added,
+to hold them firmly in place. The heads of these screws are shown in the
+plate, between the springs which press the plate-holder against its bed.
+
+To illuminate the cross-wires of the guiding eyepiece, a small electric
+lamp is used, the current for which is brought down from the storage
+battery at the main Observatory. The coarse wires have been replaced by
+spider's webs,[9] and reflectors have been introduced, to illuminate the
+declination thread. A collimating lens, placed at its principal focal
+distance from the incandescent filament of the lamp, makes the
+illumination of the wires nearly independent of their position on the
+slide, and a piece of red glass, close to the lens, effectually removes
+all danger of fogging the plate. The light is varied to suit the
+requirements of observation by rotating the reflector which throws the
+light in the direction of the eyepiece.
+
+
+[Illustration: DOUBLE-SLIDE PLATE-HOLDER OF THE CROSSLEY REFLECTOR.]
+
+
+In long exposures it is important for the observer to know at any moment
+the position of the plate with reference to its central or zero position.
+For this purpose scales with indexes are attached to both slides; but as
+they can not be seen in the dark, and, even if illuminated with red light,
+could not be read without removing the eye from the guiding eyepiece, I
+have added two short pins, one of which is attached to the lower side of
+the right ascension slide, and the other to its guide, so that the points
+coincide when the scale reads zero. These pins can be felt by the fingers,
+and with a little practice the observer can tell very closely how far the
+plate is from its central position. It would not be a very difficult
+matter to improve on this contrivance, say by placing an illuminated
+scale, capable of independent adjustment, in the field of the eyepiece,
+but the pins answer every purpose. The declination slide is changed so
+little that no means for indicating its position are necessary.
+
+In this apparatus, as originally constructed, the cross-wires of the
+guiding eyepiece were exactly in the plane of the photographic plate. The
+earlier observations made with the Crossley reflector on Mount Hamilton
+showed that this is not the best position of the cross-wires. The image of
+a star in the guiding eyepiece, which, when in the middle of its slide, is
+nearly three inches from the axis of the mirror, is not round, and its
+shape varies as the eyepiece is pushed in or drawn out. In the plane of
+the photographic plate (assumed to be accurately in focus), it is a
+crescent, with the convex side directed toward the center of the plate.
+This form of image is not suitable for accurate guiding. Outside this
+position the image changes to an arrow-head, the point of which is
+directed toward the axis, and this image can be very accurately bisected
+by the right ascension thread. As the construction of the apparatus did
+not allow the plane of the cross-wires to be changed, the wooden bed of
+the plate-holder was cut down, so as to bring the wires and the plate into
+the proper relative positions.
+
+After some further experience with the instrument, still another change
+was made in this adjustment. It was found that the focus often changed
+very perceptibly during a long exposure, and while the arrow-head image
+above described was suitable for guiding purposes, its form was not
+greatly affected by changes of focus. Between the crescent and the
+arrow-head images there is a transition form, in which two well-defined
+caustic curves in the aberration pattern intersect at an acute angle. The
+intersection of these caustics offers an excellent mark for the
+cross-wires, and is at the same time very sensitive to changes of focus,
+which cause it to travel up or down in the general pattern. The bed of the
+plate-holder was therefore raised, by facing it with a brass plate of the
+proper thickness.
+
+Why the focus of the telescope should change during a long exposure is not
+quite clear. The change is much too great to be accounted for by expansion
+and contraction of the rods forming the tube, following changes of
+temperature, while a simple geometrical construction shows that a drooping
+of the upper end of the tube, increasing the distance of the plate from
+the (unreflected) axis of the mirror, can not displace the focus in a
+direction normal to the plate, if it is assumed that the field is flat.
+The observed effect is probably due to the fact that the focal surface is
+not flat, but curved. During a long exposure, the observer keeps the
+guiding star, and therefore, very approximately, all other stars, in the
+same positions relatively to the plate; but he has no control over the
+position of the axis of the mirror, which, by changes of flexure, wanders
+irregularly over the field. The position of maximum curvature, therefore,
+also varies, and with it the focus of the guiding star relatively to the
+cross-wires, where the focal surface is considerably inclined to the field
+of view. It is certain that the focus does change considerably, whatever
+the cause may be, and that the best photographic star images are obtained
+by keeping the focus of the guiding star unchanged during the exposures.
+This is done by turning the focusing screw of the eye-end.
+
+In making the photographs of nebulae for which the Crossley telescope is at
+present regularly employed, it was at first our practice to adjust the
+driving-clock as accurately as possible to a sidereal rate, and then, when
+the star had drifted too far from its original position, on account of
+changes of rate or of flexure, to bring it back by the right-ascension
+slow motion, the observer either closing the slide of the plate-holder or
+following the motion of the star as best he could with the right-ascension
+screw. Lately a more satisfactory method, suggested by Mr. Palmer, has
+been employed. The slow motion in right ascension is of Grubb's form,[10]
+and the telescope has two slightly different rates, according to whether
+the loose wheel is stopped or allowed to turn freely. The driving-clock is
+adjusted so that one of these rates is too fast, the other too slow. At
+the beginning of an exposure the wheel is, say, unclamped, and the guiding
+star begins to drift very slowly toward the left, the observer following
+it with the screw of the plate-holder. When it has drifted far enough, as
+indicated by the pins mentioned farther above, the wheel is clamped. The
+star then reverses its motion and begins to drift toward the right; and so
+on throughout the exposure. The advantages of this method over the one
+previously employed are, that the star never has to be moved by the slow
+motion of the telescope, and that its general drift is in a known
+direction, so that its movements can be anticipated by the observer. In
+this way photographs are obtained, with four hours' exposure, on which the
+smallest star disks are almost perfectly round near the center of the
+plate, and from 2'' to 3'' in diameter.
+
+The star images are practically round over a field at least 1 inch or 16'
+in diameter. Farther from the center they become parabolic, but they are
+quite good over the entire plate, 3-1/4 by 4-1/4 inches.
+
+From these statements it will be seen that small irregularities in driving
+no longer present any difficulties. But certain irregular motions of the
+image still take place occasionally, and so far it has not been possible
+entirely to prevent their occurrence.
+
+It was found that the declination clamp (the long slow-motion handle
+attached to which is shown in the illustration) was not sufficiently
+powerful to hold the telescope firmly during a long exposure. A screw
+clamp was therefore added, which forces the toothed-declination sector
+strongly against an iron block just behind it, thus restoring, I think,
+the original arrangement of the declination clamp as designed by Dr.
+Common. This clamp holds the tube very firmly.
+
+The irregularities to which I have referred consist in sudden and
+unexpected jumps of the image, which always occur some time after the
+telescope has passed the meridian. These jumps are sometimes quite
+large--as much as one-sixteenth of an inch or 1. They are due to two
+causes: flexure of the tube, and sliding of the mirror on its bed. When
+the jump is due to sudden changes of flexure, the image moves very
+quickly, and vibrates before it comes to rest in its new position, and at
+the same time there is often heard a slight ringing sound from the tension
+rods of the tube. There seems to be no remedy for the sudden motions of
+this class. The tension rods are set up as tightly as possible without
+endangering the threads at their ends or buckling the large corner tubes.
+A round telescope tube, made of spirally-wound steel ribbon riveted at the
+crossings, would probably be better than the square tube now in use.
+
+Jumps due to shifting of the mirror are characterized by a gentle, gliding
+motion. They can be remedied, in part, at least, by tightening the copper
+bands which pass around the circumference of the mirror within its cell.
+This will be done the next time the mirror is resilvered.
+
+All that the observer can do when a jump occurs is to bring back the image
+as quickly as possible to the intersection of the cross-wires. If all the
+stars on the plate are faint, no effect will be produced on the
+photograph; but stars of the eighth magnitude or brighter will leave short
+trails. The nebula, if there is one on the plate, will, of course, be
+unaffected.
+
+Before beginning an exposure the focus is adjusted by means of a
+high-power positive eyepiece. An old negative, from which the film has
+been partially scraped, is placed in one of the plate-holders, and the
+film is brought into the common focus of the eyepiece and the great
+mirror. The appearance of the guiding star, which varies somewhat with the
+position of the guiding eyepiece on its slide, is then carefully noted,
+and is kept constant during the exposure by turning, when necessary, the
+focusing screw of the eye-end. For preliminary adjustments a ground-glass
+screen is often convenient. On it all the _DM._ stars, and even
+considerably fainter ones, as well as the nebulae of Herschel's Class I,
+are easily visible without a lens.
+
+Plates are backed, not more than a day or two before use, with Carbutt's
+"Columbian backing," which is an excellent preparation for this purpose.
+During the exposure the observer and assistant exchange places every half
+hour, thereby greatly relieving the tediousness of the work, though two
+exposures of four hours each, in one night, have proved to be too
+fatiguing for general practice. At the end of the first two hours it is
+necessary to close the slide and wind the clock.
+
+The brightness of the guiding star is a matter of some importance. If the
+star is too bright, its glare is annoying; if it is too faint, the effort
+to see it strains the eye, and changes of focus are not easily recognized.
+A star of the ninth magnitude is about right. In most cases a suitable
+star can be found without difficulty.
+
+In such an apparatus as that described above, the amount by which the
+plate may be allowed to depart from its zero position is subject to a
+limitation which has not, I think, been pointed out, although it is
+sufficiently obvious when one's attention has been called to it. It
+depends upon the fact that the plate necessarily moves as a whole, in a
+straight line which is tangent to a great circle of the sphere, while the
+stars move on small circles around the pole. The compensation for drift,
+when the plate is moved, is therefore exact at the equator only.
+
+Let the guiding star have the declination [Greek: delta]_{1}, and let a
+star on the upper edge of the plate (which, when the telescope is north of
+the zenith, and the eye-end is on the north side of the telescope, will be
+the southern edge) have the declination [Greek: delta]_{2}. Then if the
+guiding star is allowed to drift from its zero position through the
+distance _d_, the other star will drift through the distance _d_ (cos
+[Greek: delta]_{2} / cos [Greek: delta]_{1}). If the guiding star is
+followed by turning the right-ascension screw, the upper edge of the
+plate, as well as the guiding eyepiece, will be moved through the distance
+_d_. Hence there will be produced an elongation of the upper star,
+represented by
+
+  _e_ = _d_ ((cos [Greek: delta]_{2} / cos [Greek: delta]_{1}) - 1)
+
+  from which _d_ = (_e_ cos [Greek: delta]_{1}) /
+                    (cos [Greek: delta]_{2} - cos [Greek: delta_{1}]).
+
+Now, in the Crossley reflector, the upper edge of the plate and the
+guiding eyepiece are just about 3-2/3 inches, or 1 deg., apart. If _e_ is
+given, the above formula serves to determine the maximum range of the
+slide for different positions of the telescope.
+
+It has been stated farther above that the smallest star disks, on a good
+photograph, are sometimes not more than 2'' in diameter, or in a linear
+measure, about 1/20 mm. An elongation of this amount is therefore
+perceptible. There are many nebulae in high northern declinations, and
+there are several particularly fine ones in about +70 deg.. If, therefore, we
+take [Greek: delta]_{2} = 70 deg., [Greek: delta]_{1}, = 71 deg., _e_ = 0.05, and
+substitute these values, we find _d_ = 1.0 mm, which is the greatest
+permissible range of the plate in photographing these nebulae. Before I
+realized the stringency of this requirement, by making the above simple
+computation, I spoiled several otherwise fine negatives by allowing the
+plate to get too far from the center, thus producing elongated star
+images.
+
+There is a corresponding elongation in declination, the amount of which
+can be determined by an adaptation of the formula for reduction to the
+meridian, but it is practically insensible.
+
+On account of the short focal length of the three-foot mirror, the
+photographic resolving power of the telescope is much below its optical
+resolving power. For this reason the photographic images are less
+sensitive to conditions affecting the seeing than the visual images. On
+the finest nights the delicate tracery of bright lines or caustic curves
+in the guiding star is as clear and distinct as in a printed pattern. When
+the seeing is only fair these delicate details are lost, and only the
+general form of the image, with its two principal caustics, is seen. A
+photograph taken on such a night is not, however, perceptibly inferior to
+one taken when the seeing is perfect. When, however, the image is so
+blurred that its general form is barely distinguishable, the photographic
+star disks are likewise blurred and enlarged, and on such nights
+photographic work is not attempted.
+
+The foregoing account of the small changes which have been made in the
+Crossley telescope and its accessories may appear to be unnecessarily
+detailed, yet these small changes have greatly increased the practical
+efficiency of the instrument, and, therefore, small as they are, they are
+important. Particularly with an instrument of this character, the
+difference between poor and good results lies in the observance of just
+such small details as I have described.
+
+At present the Crossley reflector is being used for photographing nebulae,
+for which purpose it is very effective. Some nebulae and clusters, like the
+great nebula in _Andromeda_ and the _Pleiades_, are too large for its
+plate (3-1/4 x 4-1/4 in.), but the great majority of nebulae are very much
+smaller, having a length of only a few minutes of arc, and a large-scale
+photograph is required to show them satisfactorily. It is particularly
+important to have the images of the involved stars as small as they can be
+made.
+
+Many nebulae of Herschel's I and II classes are so bright that fairly good
+photographs can be obtained with exposures of from one to two hours; but
+the results obtained with full-light action are so superior to these, that
+longer exposures of three and one half or four hours are always preferred.
+In some exceptional cases, exposures of only a few minutes are sufficient.
+The amount of detail shown, even in the case of very small nebulae, is
+surprising. It is an interesting fact that these photographs confirm (in
+some cases for the first time) many of the visual observations made with
+the six-foot reflector of the Earl of Rosse.
+
+Incidentally, in making these photographs, great numbers of new nebulae
+have been discovered. The largest number that I have found on any one
+plate is thirty-one. Eight or ten is not an uncommon number, and few
+photographs have been obtained which do not reveal the existence of three
+or four. A catalogue of these new objects will be published in due time.
+
+Some of the results obtained with the Crossley reflector, relating chiefly
+to particular objects of some special interest, have already been
+published.[11] The photographs have also permitted some wider conclusions
+to be drawn, which are constantly receiving further confirmation as the
+work progresses. They may be briefly summarized as follows:
+
+1. Many thousands of unrecorded nebulae exist in the sky. A conservative
+estimate places the number within reach of the Crossley reflector at about
+120,000. The number of nebulae in our catalogues is but a small fraction of
+this.
+
+2. These nebulae exhibit all gradations of apparent size, from the great
+nebula in _Andromeda_ down to an object which is hardly distinguishable
+from a faint star disk.
+
+3. Most of these nebulae have a spiral structure.
+
+To these conclusions I may add another, of more restricted significance,
+though the evidence in favor of it is not yet complete. Among the objects
+which have been photographed with the Crossley telescope are most of the
+"double" nebulae figured in Sir John Herschel's catalogue (_Phil. Trans._,
+1833, Plate XV). The actual nebulae, as photographed, have almost no
+resemblance to the figures. They are, in fact, spirals, sometimes of very
+beautiful and complex structure; and, in any one of the nebulae, the
+secondary nucleus of Herschel's figure is either a part of the spiral
+approaching the main nucleus in brightness, or it can not be identified
+with any real part of the object. The significance of this somewhat
+destructive conclusion lies in the fact that these figures of Herschel
+have sometimes been regarded as furnishing analogies for the figures which
+Poincare had deduced, from theoretical considerations, as being among the
+possible forms assumed by a rotating fluid mass; in other words, they have
+been regarded as illustrating an early stage in the development of double
+star systems. The actual conditions of motion in these particular nebulae,
+as indicated by the photographs, are obviously very much more complicated
+than those considered in the theoretical discussion.
+
+While I must leave to others an estimate of the importance of these
+conclusions, it seems to me that they have a very direct bearing on many,
+if not all, questions concerning the cosmogony. If, for example, the
+spiral is the form normally assumed by a contracting nebulous mass, the
+idea at once suggests itself that the solar system has been evolved from a
+spiral nebula, while the photographs show that the spiral nebula is not,
+as a rule, characterized by the simplicity attributed to the contracting
+mass in the nebular hypothesis. This is a question which has already been
+taken up by Professor Chamberlin and Mr. Moulton of the University of
+Chicago.
+
+The Crossley reflector promises to be useful in a number of fields which
+are fairly well defined. It is clearly unsuitable for photographing the
+Moon and planets, and for star charting. On the other hand, it has proved
+to be of value for finding and photographically observing asteroids whose
+positions are already approximately known.
+
+One of the most fruitful fields for this instrument is undoubtedly stellar
+spectroscopy. Little has been done in this field, as yet, with the
+Crossley reflector, but two spectrographs, with which systematic
+investigations will be made, have nearly been completed by the Observatory
+instrument-maker. One of these, constructed with the aid of a fund given
+by the late Miss C. W. Bruce, has a train of three 60 deg. prisms and one 30 deg.
+prism, and an aperture of two inches; the other, which has a single quartz
+prism, will, I have reason to expect, give measurable, though small,
+spectra of stars nearly at the limit of vision of the telescope.
+
+The photogravure[12] of the Trifid nebula, which accompanies this article,
+was made from a photograph taken with the Crossley reflector on July 6,
+1899, with an exposure of three hours. It was not selected as a specimen
+of the work of the instrument, for the negative was made in the early
+stages of the experiments that I have described, and the star images are
+not good, but rather on account of the interest of the subject. At the
+time the photogravures were ordered no large scale photograph of the
+Trifid nebula had, so far as I am aware, ever been published.[13] The
+remarkable branching structure of the nebula is fairly well shown in the
+photogravure, though less distinctly than in the transparency from which
+it was made. The enlargement, as compared with the original negative, is
+2.9 diameters (1 mm = 13''). The fainter parts of the nebula would be
+shown more satisfactorily by a longer exposure.

+
+[3] The difficulties here referred to, about which a good deal has been
+written, seem to have had their origin in the fact that it was impossible,
+at the time of the preliminary trials, to provide the observer with an
+assistant, while the Crossley reflector is practically unmanageable by a
+single person.

+
+[8] _Mon. Not. R. A. S._, =49=, 297. The construction here described is
+not followed exactly in the Crossley apparatus. The guiding eyepiece
+slides freely when not held by a clamp. Pin-holes for preventing fogging
+are unnecessary when red light is used.
+
+[9] It so happens that the tension of the vertical thread is such that it
+begins to slacken when the temperature falls to within about 2 deg. of the dew
+point. The thread thus forms an excellent hygrometer, which is constantly
+under the eye of the observer. When the thread becomes slack, it is time
+to cover the mirrors.

+Section 1.  General Terms of Use and Redistributing Project Gutenberg-tm
+electronic works
+
+1.A.  By reading or using any part of this Project Gutenberg-tm
+electronic work, you indicate that you have read, understand, agree to
+and accept all the terms of this license and intellectual property
+(trademark/copyright) agreement.  If you do not agree to abide by all
+the terms of this agreement, you must cease using and return or destroy
+all copies of Project Gutenberg-tm electronic works in your possession.
+If you paid a fee for obtaining a copy of or access to a Project
+Gutenberg-tm electronic work and you do not agree to be bound by the
+terms of this agreement, you may obtain a refund from the person or
+entity to whom you paid the fee as set forth in paragraph 1.E.8.
+
+1.B.  "Project Gutenberg" is a registered trademark.  It may only be
+used on or associated in any way with an electronic work by people who
+agree to be bound by the terms of this agreement.  There are a few
+things that you can do with most Project Gutenberg-tm electronic works
+even without complying with the full terms of this agreement.  See
+paragraph 1.C below.  There are a lot of things you can do with Project
+Gutenberg-tm electronic works if you follow the terms of this agreement
+and help preserve free future access to Project Gutenberg-tm electronic
+works.  See paragraph 1.E below.
+
+1.C.  The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works.  Nearly all the individual works in the
+collection are in the public domain in the United States.  If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed.  Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work.  You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D.  The copyright laws of the place where you are located also govern
+what you can do with this work.  Copyright laws in most countries are in
+a constant state of change.  If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work.  The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.
+
+1.E.  Unless you have removed all references to Project Gutenberg:
+
+1.E.1.  The following sentence, with active links to, or other immediate
+access to, the full Project Gutenberg-tm License must appear prominently

+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+
+This eBook is for the use of anyone anywhere at no cost and with
+almost no restrictions whatsoever.  You may copy it, give it away or
+re-use it under the terms of the Project Gutenberg License included
+with this eBook or online at www.gutenberg.org
+
+1.E.2.  If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges.  If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the
+Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
+1.E.9.
+
+1.E.3.  If an individual Project Gutenberg-tm electronic work is posted
+with the permission of the copyright holder, your use and distribution
+must comply with both paragraphs 1.E.1 through 1.E.7 and any additional

+permission of the copyright holder found at the beginning of this work.

+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.

+electronic work, or any part of this electronic work, without

+Gutenberg-tm License.

+1.E.6.  You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form.  However, if you provide access to or
+distribute copies of a Project Gutenberg-tm work in a format other than
+"Plain Vanilla ASCII" or other format used in the official version
+posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
+you must, at no additional cost, fee or expense to the user, provide a
+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original "Plain Vanilla ASCII" or other
+form.  Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.

+     you already use to calculate your applicable taxes.  The fee is
+     owed to the owner of the Project Gutenberg-tm trademark, but he
+     has agreed to donate royalties under this paragraph to the
+     Project Gutenberg Literary Archive Foundation.  Royalty payments
+     must be paid within 60 days following each date on which you

+     sent to the Project Gutenberg Literary Archive Foundation at the
+     address specified in Section 4, "Information about donations to
+     the Project Gutenberg Literary Archive Foundation."
+
+- You provide a full refund of any money paid by a user who notifies
+     you in writing (or by e-mail) within 30 days of receipt that s/he
+     does not agree to the terms of the full Project Gutenberg-tm
+     License.  You must require such a user to return or
+     destroy all copies of the works possessed in a physical medium
+     and discontinue all use of and all access to other copies of
+     Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+     money paid for a work or a replacement copy, if a defect in the
+     electronic work is discovered and reported to you within 90 days
+     of receipt of the work.
+
+- You comply with all other terms of this agreement for free

+
+1.E.9.  If you wish to charge a fee or distribute a Project Gutenberg-tm

+
+1.F.
+
+1.F.1.  Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection.  Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2.  LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees.  YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3.  LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a
+written explanation to the person you received the work from.  If you
+received the work on a physical medium, you must return the medium with
+your written explanation.  The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund.  If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund.  If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4.  Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
+WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
+
+1.F.5.  Some states do not allow disclaimers of certain implied
+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law.  The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.
+
+1.F.6.  INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,
+promotion and distribution of Project Gutenberg-tm electronic works,
+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+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.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3.  Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service.  The Foundation's EIN or federal tax identification
+number is 64-6221541.  Its 501(c)(3) letter is posted at
+http://pglaf.org/fundraising.  Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+
+The Foundation's principal office is located at 4557 Melan Dr. S.
+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations.  Its business office is located at
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email
+business@pglaf.org.  Email contact links and up to date contact

+     gbnewby@pglaf.org
+
+
+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 http://pglaf.org
+
+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.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5.  General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone.  For thirty 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:
+
+     http://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.
