PRELIMINARY AND EXPLANATORY. Boru author and publisher of the ‘‘Key- to North American Birds” intended that the work should contain instructions for collecting and preparing birds, and that a Cueck List, accord- ing with the author’s views, should appear simultaneously with the volume. This proved impracticable: partly because the work so far overran the original estimates, that the additional expense and risk, which the publisher, an accomplished natu- ralist, generously offered to assume, seemed to the author unjustifiable ; and partly because the writer’s unexpected call to another field of official duty suddenly threw such a pressure of other engagements upon his hands that he could not just then find time to write out even so slight a treatise as this. The Cueck List and Manvat or Instruction are therefore now presented together, as a Supplement to the Key. The demand for a new Cueck List has become urgent. The last one published, and only one now in use, expresses a former state of American ornithology. That great changes— presumably for the better—have lately been made, is shown by the fact that, in round numbers, fifty species have been MANUAL. 1 2 EXPLANATORY. since ascertained to inhabit North America, while one hundred and fifty have been removed from the former list as being extralimital, invalid or otherwise untenable. Of whatever part the author may have taken in remodelling the list, it would be obviously indelicate to speak. But he cannot refrain - from alluding to the signal services of reform rendered by Mr. Allen, of Cambridge, whose stanch advocacy, under circum- stances that might have excused flinching, did so much to precipitate the changes, long while progressing and inevi- table, for which the time was at length at hand. Nor would this allusion be entirely just, did he not in the same connection refer to the thorough revision now making by Prof. Baird him- self, with the cooperation of Dr. Brewer and Mr. Ridgway, the results of which are about to appear in what promises to be one of the greatest monuments ever erected to American ornithology. ‘The notable concordance of the several writings in question, an agreement the more gratifying because a short time since it might have been considered impossible, marks an important period in the history of the science. The outlook promises well, when different premises lead up to the same conclusions, and conflicting views are reconciled. The present Cueck List, prepared in strict accordance with the Key, reflects exactly whatever of truth or error that work represents. The typography and presswork render it susceptible of use in labelling a collection.* It shows mainly three points of disagreement with the current Smithsonian List. The number of genera is reduced though not to the extent that may be desirable. It is perhaps to be regretted, that so many needless and burdensome generic names, for which Bonaparte, Cabanis, Kaup and Reichenbach are largely re- *For this purpose the List will be issued as a pamphlet by itself as well as forming part of this little volume. DS) EXPLANATORY. 3 sponsible, were adopted in Prof. Baird’s great work ;* for, sanctioned by the usage of such eminent authority, they have passed current, and are too closely ingrained in our nomen- elature to be soon eradicated. The writer feels at liberty to speak plainly, for his own skirts are not clear. Secondly, not a few species, new to North America, or to science, or both, have of late years been ascertained to inhabit this country. The third and principal variance between the present Curck List and its predecessor results from a large reduction of the number of admitted species. Part of them are excluded sim- ply because extralimital ; but most because they are considered untenable as species. In the present state of our knowledge, and under a system of nomenclature that is proven inadequate and may before long become obsolete, recognition of numerous ‘¢ Varieties ”— resultant modifications of species by physical conditions of environment —is imperative ; and what are these varieties but the rills that flow into and help to swell the mighty stream of descent with modification? The Instructions for Collecting and Taxidermy, herewith offered, are drawn almost entirely from the writer’s experience, acquired during several years he has spent, with little interrup- tion, in the study of our birds. He has collected over a wide area from Labrador to California, in northwestern territories, and in several southern states; enjoying opportunities for field investigations that no one with the least taste or aptitude for the pursuit could fail to profit by. In the matter of col- lecting, therefore, he may reasonably venture to speak with confidence. Since, furthermore, a taxidermal process that has been repeated several thousand times with fair results is by this simple circumstance proven satisfactory, he feels no diffi- *“Birds of North America” by Baird, Cassin and Lawrence. the absence of a better one. The Instructions will, itis be- lieved, enable any one to become reasonably proficient in certain ee of the indispensable qualifications of a good working ornithol- r Ey Ae ogist. He intends to take what may or may not be a liberty, Psy and to presume that the reader is entirely inexperienced in — | My field-work; and he begs the further privilege of waiving © ( formality, that he may be allowed to address the reader very familiarly, much as if chatting with a friend’ on a subject of Bik. mutual interest. | ap RN Bendire’s Mocking-thrush, Harporhynchus Bendiret Coues.

Under some circumstances you may trap or snare birds, catch them with bird-lime, or use other devices; but such cases are exceptions to the rule that you will shoot birds, and for this purpose no weapon compares with the one just mentioned. The soul of good advice respecting the selection of a gun, is, get the best one you can afford to buy; go the full length of your purse in the matters of material and workmanship. To say nothing of the prime requisite, safety, or of the next most desirable quality, efficiency, the durability of a high-priced gun makes it cheapest in the end. Style of finish is obviously of little consequence, except as an index of other qualities ; for inferior guns rarely, if ever, display the exquisite appoint- ments that mark a first-rate arm. There is really, so little choice among good guns that nothing need be said on this score ; you cannot miss it if you pay enough to any reputable maker or reliable dealer. But collecting is a specialty, and some guns are better adapted than others to your particular purpose, which is the destruction, as a rule, of small birds, at moderate range, with the least possible injury-to their plumage. Probably three-fourths or more of the birds of a miscellaneous collection average under the size of a pigeon, and were shot within thirty yards. ~~ WORKING TABLE. Nf} ceptacle for offal, for this only makes another article to be cleaned ; lay down a piece of paper for the refuse, and throw the whole away. A perfectly smooth surface is desirable. I generally have a large pane of window glass on the table be- fore me. It will really be found advantageous to have a scale of inches scratched on the edge of the table; only a small part of it need be fractionally subdivided ; this replaces the foot- rule and tape-line, just as the tacks of a dry goods counter answer for the yardstick. You will find it worth while to rig some sort of a derrick arrangement, which you can readily devise, on’one end of the table, to hitch your hook to, if you hang your birds up to skin them; they should swing clear of everything. The table should have a large general drawer, with the little drawer for gypsum and arsenic already men- tioned, unless these be kept elsewhere. Stuffing may be kept in a box under the table, and make a nice footstool; or ina bag slung to the table leg. §35. Query: Have you cleansed the bird’s plumage? Have you plugged the mouth, nostrils and vent? Have you meas- ured the specimen and noted the color of the eyes, bill and feet, and prepared the labels, and made the entry in the regis- ter? Have you got all your apparatus within arm’s length? Then we are ready to proceed. a §36.

Take scissors, stick in the pointed blade just over the end of the breast bone, cut in a straight line thence to and into the anus; cut extremely shallow. ¢ : Take the forceps in your left hand, and scalpel in your right, both held pen-wise, and with the forceps seize and lift up one of the edges of the cut skin, gently pressing away the belly- walls with the scalpel-point ; no cutting is required; the skin may be peeled off without trouble. Skin away till you meet- an obstacle ; it is the thigh. Lay down the instruments ; with your left hand take hold of the leg outside at the shank; put * Reverse this and following directions for position, if you are left-handed. j The motion is exactly like stroking the right and left sides of a moustache apart; you would never dress the hairs smoothly away from the middle line, by poking from ends to root; nor will the feathers stay aside, unless stroked away from base to tips. +The skin over the belly is thin as tissue paper in a small bird; the chances are you will at first cut the walls of the belly too, opening the cavity; this is no great matter, for a pledget of cotton will keep the bowels in; nevertheless, try to di- vide skin only. Reason for cutting into anus: this orifice makes a nice natural termination of the incision, buttonhole-wise, and may keep the end of the cut from tearing around the root of the tail. Reason for beginning to cut over the edge of the sternum: the muscular walls of the belly are very thin, and stick so close to the skin that you may be in danger of attempting to remove them with the skin, instead of removing the skin from them; whereas, you cannot remove anything but skin from over the breast bone, so you have a guide at the start. You can tell skin from belly-walls, by its livid, translucent whitishness instead of redness. Ff CHAPTER VI. HOW TO MAKE A BIRDSKIN. A. The regular process.

Take the scissors in your right hand; tuck one blade under the concavity of the knee, and sever the joint at a stroke; then the thigh is left with the rest of the body, while the rest of the leg is dissevered and hangs only by skin. Push the leg further up till it has slipped out of its sheath of skin, like a finger out of a glove, down to the heel-joint. You have now to clear off the flesh and leave the bone’ there; you may scrape till this is done, but there is a better way. Stick the closed points of the scissors in among the muscles just be- low the head of the bone, then separate the blades just wide enough to grasp the bone; snip off its head; draw the head to one side; all the muscles follow, being there attached ; strip them downward from the bone; the bone is left naked, with the muscle hanging by a bundle of tendons (‘‘leaders”’) at its foot; sever these tendons collectively at a stroke.* Draw the leg bone back into its sheath, and leave it. Repeat all the foregoing steps on the other side of the bird. If you are bothered by the skin-flaps settling against the belly-walls, in- sert a fluff of cotton. Meep the feathers out of the wound ; cotton and the moustache movement will do it. Next you must sever the tail from the body, leaving a small ‘‘ pope’s- nose” for the feathers to stay stuck into. Put the bird in the hollow of your lightly closed left hand, tail upward, belly toward you; or, if too large for this, stand it on its breast on the table in similar position. Throw your left forefinger across the front of the tail, pressing a little backward; take the scis- sors, cut the end of the lower bowel free first, than peck away at bone and muscle with cautious snips, till the tail-stump is dissevered from the rump, and the tail hangs only by skin. Now you have the rump-stump protruding naked; the legs * This whole performance will occupy about three seconds, after practice; and you may soon discover you can nick off the head of the bone of a small bird with the thumb-nail. + You will soon learn fo do it all at one stroke; but you cannot be too careful at ‘first; you are cutting right down on to the skin over the top of the pope’s-nose, and if you divide this, the bird will part company with its tail altogether. 60 HOW TO MAKE A BIRDSKIN. Mee dangling on either side; the tail hanging loose over the bird’s ~ back between them. Lay down scissors; take up forceps* in — your left hand; with them seize and hold the stump of the rump; and with point or handle of scalpel in the other hand, with finger tips, or with thumb-nail (best), gently press down on and peel away skin.t No cutting will be required (usually) till you come to the wings: the skin peels off (usually) as a easily as an orange rind; as fast as it is loosened, evert it; that is, make it continually turn itself more and more com- = pletely inside out. Work thus till you are stopped by the : os obtruding wings.t You have to sever the wing from the body = at the shoulder, just as you did the leg at the knee, and leave ‘ it hanging by skin alone. Take your scissors,§ as soon as the upper arm is exposed, and cut through flesh and bone alike at one stroke, a little below (outside of) the shoulder-joint. Do the same with the other wing. As soon as the wings are ~~ severed the body has been skinned to the root of the neck; the process becomes very easy ; the neck almost slips out of its sheath of itself; and if you have properly attended to keeping the feathers out of the wound and to continual ever- * Or at this stage you may instead stick a hook into a firm part of the rump, and hang up the bird about the level of your breast; you thus have both hands free to work with. This is advisable with all birds too large to be readily taken in hand and will help you at jirst, with any bird. But there is really no use of if with a small bird,and you may as well learn the best way of working at first as after- Wy ward. tem j The idea of the whole movement is exactly like ungloving your hand from the wrist, by turning the glove inside out to the very finger tips. Some people say, pull off the skin; I say never pull a bird’s skin under any circumstances: push i of, always operating at lines of contact of skin with body, never upon areas of skins already detached. t The elbows will get in your way before you reach the point of attack, viz., the shoulder, unless the wings were completely relaxed (as was essential, indeed, if you measured alar expanse correctly). Think what a difference it would make, were you skinning a man through a slit in the belly, whether his arms were stretched above his head, or pinned against his ribs. It is just the same with a — bird. When properly relaxed the wings are readily pressed away toward the bird’s head, so that the shoulders are encountered before the elbows. § Shears will be required to erash through a large arm-bone. Or, you may with the scalpel unjoint the shoulder. The joint will be found higher up and deeper among the breast muscles than you might suppose, unless you are used to carving fowls at table. With a small bird, you may snap the bone with the thonb aa tear asunder the muscles in an instant. PROCESS OF SKINNING. 61 sion of the skin, you now find you have a naked body con- nected dumb-bell-wise by a naked neck to a cap of reversed skin into which the head has disappeared, from the inside of which the legs and wings dangle, and around the edges of which is a row of plumage and a tail.* Here comes up an im- portant consideration: the skin, plumage, legs, wings and tail together weigh something — enough to stretch unduly the skin of the neck, from the small cylinder of which they are now suspended; the whole mass must be supported. For small birds, gather it in the hollow of your left hand, letting the body swing over the back of your hand out of the way; for large ones, rest the affair on the table or your lap. To skin the head, secure the body in the position just indicated, by confining the neck between your left thumb and forefinger ; bring the right fingers and thumb to a cone over the head, and draw it out with gentle force; or, holding the head itself be- tween the left thumb and forefinger, insert the handle of the scalpel between the skin and skull, and pry a little, .to enlarge . the neck-cylinder of skin enough to let the head pass. It will generally{ slip out of its hood very readily, as far as its greatest diameter ;§ there it sticks, being in fact pinned by the ears. Still holding the bird as before, with the point of the scalpel handled like a nut-picker, or with your thumb-nail, detach the delicate membrane that lines the ear-opening; do the same for the other ear. The skull is then shelled out to the eyes, and will skin no further of its own accord, being * You find that the little straight cut you made along the belly has somehow be- come a hole larger than the greatest girth of the bird; be undismayed; it is all right. {if you have up to this point properly pushed off the skin instead of pulling it, there is as yet probably no stretching of any consequence; but in skinning the head, which comes next, it is almost impossible for a beginner to avoid stretching to an extent involving great damage to the good looks of askin. Try your utmost, by delicacy of manipulation at the lines of contact of skin with flesh and only there, to prevent lengthwise stretching. Crosswise distension is of no conse- quence—in fact more or less of it is usually required to skin the head, and it tends to counteract the evils of undue elongation. { The special case of head too large for the calibre of the neck is treated beyond. § And you will at once find a great apparent increase of amount of free skin in your hand, owing to release and extension of all that was before shortened in length by circular distension, in enlargement of the neck-cylinder. 62 HOW TO MAKE A BIRDSKIN. again attached by a membrane, around the border of the eye- socket. Holding the scalpel as before, run its edge around an arc (a semicircle is enough to let you into the orbit) of the circumference, dissevering the membrane from the bone. Re- verse the scalpel, and scoop out the eyeball with the end of | the handle; you bring out the eye betwixt the ball of your thumb and the handle of the instrument, tearing apart the optic nerve and conjunctival tissue, but taking care not to open the eyeball* nor lacerate the eyelids. Do the same with the other eye. The head isthen skinned far enough; there is no use of getting quite to the base of the bill. You have now to get rid of the brain and flesh of the nape and jaws,y and leave most of the skull in; the cranial dome makes the only perfect *¢ stuffing” for the skin of the head. This is all done at once by only four particular cuts. Hold the head between your left thumb and fingers, the bill pointing towards you, the bird’s palate facing you; you observe a space bounded behind by the base of the skull where the neck joins, in front by the floor of the mouth, on either side by the prongs of the under jaw — these last especially prominent. Take the scissors; stick one blade just inside one branch of the lower jaw, thence into the eye-socket which lies below (the head being upside down) thence into the brain-box; make a cut parallel with the jaw, just inside of it, bringing the upper scissor blade perpendicu- larly downward crashing through the skull just inside of the angle of the jaw. Duplicate this cut on the other side. Con- nect the anterior ends of these cuts by a transverse one across the floor and roof of the mouth. Connect the posterior ends of the side cuts by one across the back of the skull near its base —just where the nape-muscle ceases to override the cra- * An eyeball is much larger than it looks from the outside; if you stick the instrument straight into the socket, you may punch a hole in the ball t out the water; a very disagreeable complication. Insinuate the knife-handle close to the rim of the socket, and hug the wall of the cavity throughout. t+ You may of course at this stage cut off the neck at the nape, punch a hole in the base of the skull, dig out the brains, and scrape away at the jaw-muscles till you are satisfied or tired; an unnecessary job, during which the skin may haye become dry and shrivelled and hard to turn right side out. The operation de- scribed in the text may require ten seconds, perhaps. PROCESS OF SKINNING. 63 nium. You have enclosed and cut out a squarish-shaped mass of bone and muscle, and on gently pulling the neck (to which of course it remains attached), the whole affair comes out, bringing the brain with it, but leaving the entire roof of the skull supported on a scaffolding of jaw-bone. It only remains to skin the wings. Seize the arm-stump with fingers or for- ceps ; the upper arm is readily drawn from its sheath as far as the elbow; but the wing must be skinned to the wrist (carpus —‘‘bend of the wing”); yet it will not come out so easily, because the secondary quills grow to one of the forearm bones (the ulna) pinning down the skin the whole way along a series of points. To break up these connections, hold the upper arm firmly with the left thumb and forefinger, the convexity of the elbow looking towards you; press the right thumb-nail closely against the back edge of the ulna, and strip downward, scrap- ing the bone with the nail the whole way.* If you only hit the line of adhesion, there is no trouble at all about this. Now you want to leave in one of the two forearm bones, to preserve sufficiently the shape of the limb, but to remove the other, with the upper arm bone and all the flesh. It is done in a moment; stick the point of the scissors between the heads of the two forearm bones, and cut the hinder one (ulna) away from the elbow ; then the other forearm bone (radius), bearing on its year end the elbow and the whole upper arm, is to be stripped away from the ulna, taking with it the flesh of the forearm, and to be cut off at its far end close to the wrist-joint, one stroke severing the bone and all the tendons that pass over the wrist to the hand; then the ulna, bare of flesh, is alone left in, attached at the wrist. Draw gently on the wing from the out- side till it slips into the natural position whence you everted it. Do the same for the other wing. This finishes the skin- ning process. The skin is now to be turned right side out. Begin any way you please, till you see the point of the bill reappearing among the feathers; seize it with fingers or for- ceps as convenient, and use it for gentle traction. But by no means pull it out by holding on to the rear end of the skin — * For special case of wing too large to be handled thus, see beyond. 64 HOW TO MAKE A BIRDSKIN. that would infallibly stretch the skin. Holding the bill, make a cylinder of your left hand and coax the skin backward with a sort of milking motion. It will come easily enough, until the final stage of getting the head back into its skull cap; this may require some little dexterity; but you cannot fail to get the head in, if you remember what you did to get it out. When this is fairly accomplished, you for the first time have the pleasure of seeing something that looks like a birdskin. Your next* care is to apply arsenic. Lay the skin on its back, the opening toward you and wide spread, so the interior is in view. Run the scalpel-handle into the neck to dilate that cyl- inder until you can see the skull; find your way to the orifices of the legs and wings; expose the pope’s-nose; thus you have not only the general skin surface, but all the points where some traces of flesh were left, fairly in view. Shovel in arsenic; dump some down the neck, making sure it reaches and plenti- ~ fully besprinkles the whole skull; drop a little in each wing hole and leg hole; leave a small pile at the root of the tail; strew some more over the skin at large. The simple rule is, put in as much arsenic as will stick anywhere. Then close the opening, and shake up the skin; move the head about by the bill; rustle the wings and move the legs; this distrib- utes the poison thoroughly. If you have got in more than is necessary, as you may judge by seeing it piled up dry, any- where, hold the skin with the opening downward over the poi- son-drawer, and give it a flip and let the superfluous powder fall out. Now for the ‘‘make up,’ upon which the beauty of the preparation depends. First get the empty skin into good shape. Let it lie on its back; draw it straight out to its nat- ural length. See that the skin of the head fits snugly; that the eyes, ears and jaws are in place. Expand the wings to make sure that the bone is in place, and fold them so that the quills override each other naturally ; set the tail feathers shin- *Some direct the poisoning to be done while the.skin is still wrong side out; and it may be very thoroughly effected at that stage. I wait, because the arsenic generally strews over the table in the operation of reversing the skin, if you use as much as I think advisable; and it is better to have a cavity to put it into than a surface to strew it on. STUFFING. ! 65 glewise also; draw down the legs and leave them straddling wide apart. Give the plumage a preliminary dressing ; if the skin is free from kinks and creases, the feathers come naturally into place; particular ones that may be awry should be set right, as may be generally done by stroking, or by lifting them. free repeatedly, and letting them fall; if any (through care- lessness) remain turned into the opening, they should be care- fully picked out. Remove all traces of gypsum or arsenic with the feather duster. The stuffing is to be put in through the opening in the belly; the art is to get in just enough, in the right places. It would never do to push in pellets of cot- ton, as you would stuff a pillew-case, till the skin is filled up ; no subsequent skill in setting could remove the distortion that would result. It takes just fowr* pieces of stuffing — one for each eye, one for the neck, and one for the body; while it re- quires rather less than half as much stuffing as an inexperienced person might suppose. ‘Take a shred of cotton that will make a tight ball as large as the bird’s eye; stick it on the end of your knitting needle, and by twirling the needle whilst the cotton is confined in your finger tips, you make a neat ball. Introduce this through the belly-opening, into the eyesocket ; if you have cut away skull enough, as already directed, it will go right in; disengage the needle with ‘a reverse twirl, and withdraw it. Take hold of the bill with one hand, and with the forceps in the other, dress the eyelids neatly and naturally over the elas- tic substance within. Repeat for the other eye. Take next a shred of cotton that will roll into a firm cylinder rather less than the size of the bird’s neck. Roll it on the needle much * For any ordinary bird up to the size of acrow. It is often directed that the leg bones and wing bones be wrapped with cotton or tow. I should not think of putting anything around the wing bones of any bird up to the size of an eagle, swan or pelican. Examination of a skinned wing will show how extremely com- pact it is, except just at the shoulder. What you remove will never make any dif- ference from the outside, while you would almost inevitably get in too much, not of the right shape, and make an awkward bulging no art would remedy; I say, then, leave the wings of all but the largest birds empty, and put in very little under any circumstances. As for legs, the whole host of small perching birds need no wrapping whatever; depend upon it you will make a nicer skin without wrapping. But large birds and those with very muscular or otherwise prominent legs must have the removal of flesh compensated for. Itreat of these cases beyond. MANUAL. 5 66 HOW TO MAKE A BIRDSKIN. as you did the eyeball, introduce it in the same way, and ram it firmly into the base of the skull; disengage the needle by twisting it the other way, and withdraw it, taking care not to dislodge the cotton neck. If now you peep into the skin you will see the end of this artificial neck; push it up against the skin of the breast—it must not lie down on the back between the shoulders.* The body-wad comes next; you want to imi- tate the size and shape of the bird’s trunk. Take a mass of cotton you think will be enough, and take about half of this ; that will be plenty (cotton is very elastic). It should make a tolerably firm ball, rather egg-shaped, swelling at the breast, smaller behind. If you simply squeeze up the cotton, it will not stay compressed ; it requires a motion something like that which bakers employ to knead dough into the shape of a loaf. Keep tucking over the borders of the cotton till the desired shape and firmness are attained. Insert the ball between the blades of the forceps in such way that the instruments con- fine the folded-over edges, and with a wriggling motion insin- uate it aright into the body. Before relaxing the forceps, put your thumb and forefinger in the bird’s armpits, and pinch the shoulders together till they almost touch; this is to make sure that there is no stuffing between the shoulders—the whole mass lying. breastwards. Loosen the forceps and withdraw them. If the ball is rightly made and tucked in, the elasticity of the cotton will chiefly expend itself in pufting out the breast, which is just what is wanted. Be careful not to push the body too far in; if it impacts against the skin of the neck, this will infallibly stretch, driving the shoulders apart, and no art will remedy the unsightly gape resulting. You see I dwell on this * Although a bird’s neck is really, of course, in direct continuation of the back- bone, yet the natural sigmoid curve of the neck is such that it virtually takes de- parture rather from the breast, its lower curve being received between the prongs of the merrythought. This is what we must imitate instead of the true anatomy. If you let the end of the neck lie between the shoulders, it will infallibly press them apart, so that the interscapular plumage cannot shingle over the scapular as it should, and a gaping place, showing down or even naked skin, will result. Likewise if the neck be made foo large (the chances are that way, at first), the same result follows. These seemingly trifling points are very important indeed; I never made a decent birdskin till I learned to get the neck small enough, and to shove the end of it against the breast. : SETTING THE SKIN. 67 matter of the shoulders; the whole knack of stuffing correctly focusses just over the shoulders. If you find you have made the body too large, pull it out and make a smaller one; if it fits nicely about the shoulders but is too long to go in, or too puffy over the belly, let it stay, and pick away shreds at the open end till the redundancy is remedied. Your bird is now stuffed. Close the opening by bringing the edges of the original cut together. There is no use of sewing* up the cut, for a small bird; if the stuffing is correct, the feathers will hide the opening, and if they do not, it isno matter. You are not making an object for a show case, but for a naturalist’s cabinet. Supposing you to have been so far successful, little remains to be done; the skin already looks very much like a dead bird; you have only to give the finishing touches, and “set” it. Fixing the wings nicely is a great point. Fold each wing closely; see that the carpal bend is well defined, that the coverts show their several oblique rows perfectly, that all the quills override each other like shingles. ‘luck the folded wings close up to the body —rather on the bird’s back than along its sides; see that the wing tips meet over the tail (under the tail as the bird lies on its back); let the carpal angle nestle in the plumage ; have the shoulders close together, so-+that the interscapulars shingle over the scapulars. If the wing be pressed in too tightly, the scapulars will rise up on end; there must be neither furrow nor ridge about the inser- tion of the wings ; every thing must lie perfectly smooth. At this stage of the process, I generally lift up the skin gingerly, and let it slip head first through one hand after the other, press- ing here or there to correct a deformity, or uniformly, to make the whole skin compact. The wings set, next bring the legs together, so that the bones within the skin lie parallel with each other; bend the heel-joint a little, to let the tarsi cross each other about their middle; lay them sidewise on the tail, * But sew it up, if you please, though you may be perhaps giving the man who subsequently mounts the bird the trouble of ripping out the stitches. Stitches however, will not come amiss with alarge bird. I generally, in such cases, pin the edges of the cut in one or more places. 68 | HOW TO MAKE A BIRDSKIN. so that the naturally flexed toes lie flat, all the claws mutually facing each other. See that the neck is perfectly straight, and, if anything, shortened rather than outstretched ; have the crown of the head flat on the table, the bill pointing straight forward,* the mandibles shut tightly.; Never attempt any ‘“‘ fancy.” atti- tudes with a birdskin; the simpler and more compactly it is made up the better.{ Finally, I say, hang over your bird (if you have time); dress better the feathers that were well dressed before; perfect every curve; finish caressingly, and put it away tenderly, as you hope to be shriven yourself when the time comes. There are several ways of laying a birdskin. A common, easy and slovenly way is to thrust it head first into a paper cone ; but it makes a hollow-chested, pot-bellied object unpleasant to see, and renders your nice work on the make-up futile. A paper cylinder, corresponding in calibre to the greatest girth of the birdskin, binds the wings well, and makes a good ordi- nary specimen— perhaps better than the average. Remarking that there are some detestable practices, such as hanging up a bird by a string through the nose (methods only to be men- * Exceptions. Woodpeckers, ducks and some other birds treated of in §39, are best set with the head flat on one side, the bill pointing obliquely to the right or left; owls, with the bill pointing straight up in the air as the bird lies on its back. tif the mandibles gape, run a thread through the nostrils and tie it tightly under the bill. Or, since this injures the nostrils (and we frequently want to examine their structure) stick a pin in under the bill close to the gonys, drawing it obliquely into the palate. Sometimes the skin of the throat looks sunken betwixt the sides of the jaw. A mere shred of cotton introduced with forceps through the mouth will obviate this. t Don’t cock up the head, trying to impart a knowing air—it cannot be done, and only makes the poor bird look ridiculous. Don’t lay the skin on one side, with the legs in perching position, and don’t spread the wings—the bird will never perch nor fly again, and the suggestion is unartistic because incongruous. The only permis- sible departure from the rule of severe simplicity is when some special ornament, as a fine crest, may be naturally displayed, or some hidden markings are desired to be brought out, or a shape of tail or wing to be perpetuated; but in all such cases the “flowery” inclination should be sparingly and judiciously indulged. It is, however, frequently desirable to give some special set to hide a defect, as loss of plumage, etc.; this may often be accomplished very cunningly, with excellent re- sult. No rules for this can be laid down, since the details vary in every case; buf in general the weak spot may be hidden by contracting the skin of the place and then setting the bird in an attitude that naturally corresponds, thus making a vir-_ tue of necessity. a ee DRYING AND PACKING SKINS. 69 tioned to be condemned), I will tell you the easiest and best way, by which the most elegant and tasteful results are almost necessarily secured. The skins are simply laid away in cotton, just as they come from your hands. Take a considerable wad of cotton, make a “bed” of it, lay the specimen in, and tuck it up nicely around the edges. In effect, I generally take a thin sheet of cotton wadding, the sizing of which confers some textile consistency, and wrap the bird completely but lightly in it. By loosening or tightening a trifle here or there, laying down a‘‘ pillow” or other special slight pressure, the most deli- cate contour-lines may be preserved with perfect fidelity. Un- necessary pother is sometimes made about drying skins; the fact being that under ordinary circumstances they could not be kept from drying perfectly ; and they dry in exactly the shape they are set, if not accidentally pressed upon. At sea, how- ever, or during unusually protracted wet weather, they of course dry slowly, and may require some attention to prevent mildew, and even souring, especially in the cases of very large, thick-skinned or greasy specimens. ‘Thorough poisoning, and drying by a fire, or placing in the sun, will always answer. Very close packing retards drying. When travelling or oper- ating under other circumstances requiring economy of space, you must not expect to turn out your collection in elegant order. Perfection of contour-lines can only be secured by put- ting each specimen away by itself; undue pressure is always liable to produce unhappily ouwtré configuration of a skin. Trays in a packing box are of great service in limiting possi- bilities of pressure; they should be shallow; for one four inches deep will take a well stuffed hen hawk, for example, or accommodate 3—6 sparrows a-top of each other. It is well to sort out your specimens somewhat according to size, to keep heavy ones off little ones; though the chinks around the former may usually be economized with advantage by packing In the less valuable or the less’ neatly prepared of the latter. When limited to a travelling chest, I generally pass in the skins as fast as made, packing them ‘‘solid” in one sense, yet hunting up a nice resting place for each. If each rests in its 70 HOW TO MAKE A BIRDSKIN. own cotton coffin, it is astonishing how close they may be laid without harm; and how many will go in a given space —a tray 30X18X4 inches will easily hold three hundred and fifty birds six inches long. As a tray fills up, the drier ones first put in may be submitted to more pressure. A skin originally dried in good shape may subsequently be pressed perfectly flat with- out material injury ; the only thing to avoid being contortion. The whole knack of packing birds corresponds to that of filling a trunk solidly full of clothes—as may easily be done without damage to an immaculate shirt-front. Finally, I would say, never put away a bird unlabelled, not even for an hour; you may forget it, or die. Never tie a label to a bird’s bill, wing or tail; tie it securely to both legs where they cross, and it will be just half as liable to become detached as if tied to one leg only. Never paste a label, or even a number, on a bird’s plu- mage. Never put in glass eyes before mounting. Never paint or varnish a bird’s billor feet. Never replace missing plumage of one bird with the feathers of another—no, not even if the birds came out of the same nest. B. Special Processes; Complications and Accidents. §37. Tue foregoing method of procedure is a routine prac- tice applicable to three-fourths if not nine-tenths of the ‘‘ gen- eral run” of birds. But there are several cases requiring a modification of this programme; while several circumstances may tend to embarrass your operations. The principal special conditions may therefore be separately treated to your advan- tage. §38. Size. Other things being equal, a large bird is more difficult to prepare than a small one. In one case, you only need a certain delicacy of touch, easily acquired and soon be- coming mechanical; in the other, demand on your strength may be made, till your muscles ache. It takes longer, too ;* * The reader may be curious to know something of the statistics on this score —how long it ought to take him to prepare an ordinary skin. He can scarcely imagine, from his first tedious operations, how expert he may become, not only in 4 i q SPECIAL PROCESSES. all I could put away a dozen sparrows in the time I should spend over an eagle, and I would rather undertake a hundred hum- ming birds than one ostrich. For “large” birds, say anything from a hen hawk upward, various special manipulations I have directed may be foregone, while however you observe their gen- eral drift and intent. You may open the bird as directed, or, turning it tail to you, cut with a knife.* Forceps are rarely required —there is not much that is too small to be taken in hand. As soon as the tail is divided, hang up the bird by the rump, so you will have both hands free. Let it swing clear of the wall or table, at any height most convenient. The steel hooks of a dissecting case are not always large enough; use a stout fish-hook with the barb filed off. Work with your nails, assisted by the scalpel if necessary. I know of no bird, and I think there is none in this country at least, the skin of which is so internally adherent by fibrous or muscular tissue as to require actual dissecting throughout; a pelican comes perhaps as near this as any; but in many cases the knife may be con- stantly employed with advantage. Use it with long clean beauty of result, but in rapidity of execution. Ihave seen taxidermists make good small skins at the rate of ten an hour; but this is extraordinary. The quickest work Iever did myself was eight an hour, or an average of seven and ahalf minutes apiece, and fairly good skins. But I picked my birds, all small ones, well shot, labelled, measured and plugged beforehand, so that the rate of work was excep- tional besides including only the actual manipulations from first cut to laying away. No one averages eight birds an hour, even excluding the necessary preliminaries of cleansing, plugging, etc. Four birds an hour, everything included, is good work. A very eminent ornithologist of this country, and an expert taxidermist, once laid a whimsical wager, that he would skin and stuff a bird before a certain friend of his could pick all the feathers off a specimen of the same kind, I forget the time, but he won, and his friend supped that night on some very tough game! * Certain among larger birds are often opened elsewhere than along the belly — with what advantage I cannot say from my own experience. Various water birds, such as loons, grebes, auks, gulls and ducks (in fact any swimming bird with dense under plumage) may be opened along the side by a cut under the wings from the shoulder over the hip to the rump; the cut is completely hidden by the make-up, and the plumage is never ruffled. ButI see no necessity for this; for, asa rule, the belly opening can, if desired, be completely effaced with due care; though a very greasy bird with white under plumage generally stains where opened, in spite of every precaution. Such birds as loons, grebes, cormorants and penguins are often opened by a cut across the fundament from one leg to the other; their con- formation in fact suggests and favors this operation. I have often seen water birds slit down the back; but I consider it very poor practice. 42 HOW TO MAKE A BIRDSKIN. sweeping strokes, hugging the skin rather than the body. The knee and shoulder commonly require disarticulation, unless you use bone-nippers or strong shears; the four cuts of the skull may presuppose avery able-bodied instrument —even a chisel. ‘The wings will give you the most trouble, and they require a special process ; for you cannot readily break up the adhesions of the secondary quills to the ulna, nor is it desi- rable that very large feathers should be deprived of this natural ‘support. Hammer or nip off the great head of the upper arm- bone, just below the insertion of the breast muscles; clean the rest of that bone and leaveitin. Tie a string around it (what sailors call ‘‘two half hitches” gives a secure hold on the bony cylinder), and tie it to the other humerus, inside the skin, so that the two bones shall be rather less than their natu- ral distance apart. After the skin is brought right side out, attack the wings thus: spread the wing under side uppermost, and secure it on the table by driving a tack or brad through the wrist-joint ; this fixes the far end, while the weight of the skin steadies the other. Raise a whole layer of the under wing coverts, and make a cut in the skin thus exposed, from elbow to wrist, in the middle line between the two forearm bones. Raise the flaps of skin, and all the muscle is laid bare ; it is to be removed. ‘This is best done by lifting each muscle from its bed separately, slipping the handle of the scalpel under the individual bellies ; there is little if any bony attach- ment except at each end, and this is readily severed. Strew in arsenic; a little cotton may be used to fill the bed of mus- cle removed from a very large bird; bring the flaps of skin together, and smooth down the coverts ; you need not be par- ticular to sew up the cut, for the coverts will hide the opening ; in fact, the operation does not show at all after the make- up. Stuffing of large birds is not commonly done with only the four pieces already directed. The eyeballs, and usually the neck-cylinder, go in as before; the body may be filled any way you please, provided you do not put in too much stuffing nor get any between the shoulders. All large birds had better have the leg bones wrapped to nearly natural size. Observe . LARGE HEADED BIRDS. 73 that the leg-muscles do not form a cylinder, but a cone; let the wrapping taper naturally from top to bottom. Attention to this point is necessary for all large or medium sized birds with naturally prominent legs. The large finely feathered legs of a hawk, for example, ought to be well displayed ; with these birds, and also with rails, etc., moreover, imitate the bulge of the thigh with a special wad laid inside the skin. Large birds commonly require also a special wad introduced by the mouth, to make the swell of the throat; this wad should be rather fluffy than firm. As a rule do not fill out large birds to their natural dimensions; they take up too much room. Let the head, neck and legs be accurately prepared, but leave the main cavity one-third if not one-half empty; no more is required than will fairly smooth out creases in the skin. Reduce bulk rather by flattening out than by general. compression. Use tow instead of cotton; and if at all short of tow, economize with paper, hay, etc., at least for the deeper portions of the main stuffing. Large birds may be “‘set” in a great quantity of tow; wrapped in paper, much like any other parcel; or simply left to dry on the table, the wings being only supported by cushioning or other suitable means. §39. SHapr. Some special configurations have been noticed in the last paragraph, prematurely perhaps, but leading di- rectly up to further considerations respecting shape of certain birds as-a modifying element in the process of preparation. As .for skinning, there is one extremely important matter. Most ducks, many woodpeckers, flamingoes, and doubtless some others, with which I am not familiar, cannot be skinned in the usual way, because the head is too large for the calibre of the neck and cannot be drawn through. In such cases, skin as usual to the base of the skull, cut off the head there (in- side the skin of course), and operate upon it, after turning the skin right side out, as follows:—Part the feathers carefully” in a straight line down the back of the skull, make a cut through the skin, just long enough to permit the head to pass, draw out the skull through this opening, and dress it as already 74 HOW TO MAKE A BIRDSKIN. directed. Return it, draw the edges of the cut nicely to- gether, and sew up the opening with a great many fine stitches. Simple as it may appear, this process is often embarrassing, for the cut has an unhappy tendency to wander about the neck, enlarging itself even under the most careful manipulation ; while the feathers of the parts are usually so short, that it is difficult to efface all traces of the operation. I consider it very disagreeable ; but for ducks I know of no alternative. I have however found out a way to avoid it with woodpeckers, excepting the very largest: it is this:— Before skinning, part the eyelids, and plunge the scalpel right into the eyeballs; seize the cut edge of the ball with the forceps, and pull the eye right out. It may be dextrously done without spilling the eye water on the plumage; but, for fear of this. previously put a little pile of plaster on the spot. Throw arsenic into the socket, and then fill it with cotton poked in between the lids. The eyes are thus disposed of. Then, in skinning, when you come to the head, dissever it from the neck and work the skull as far out as you can; it may be sufliciently exposed, in all cases, for you to gouge out the base of the skull with the scis- sors, and get at the brain to remove it. Apply an extra large dose of arsenic, and you will never hear from what jaw-muscle has been left in. In all these cases, as already remarked, the head is preferably set lying on one side, with the bill pointing obliquely to the right or left. Certain birds require a special mode of setting; these are, birds with very long legs or neck, or both, as swans, geese, pelicans, cormorants, snakebirds, loons, and especially cranes, herons, ibises and flamingoes. Long legs should be doubled completely on themselves by bending at the heel-joint, and either tucked under the wings, or laid on the under surface; the chief point is to see that the toes lie flat, so that the claws do not stick up, to catch in things or get broken off. A long neck should be carefully folded; not at a sharp angle with a crease in the skin, but with a short curve, and brought round either to the side of the- bird or on its breast, as may seem most convenient. The ° object is to make a ‘“‘bale” of the skin as nearly as may be, THIN SKINS, ETC.—FAT. 75 and when it is properly effected it is surprising what little space a crane, for instance, occupies. But it is rarely, if ever, admis- sible to bend a tail back on the body however inconveniently long it may be. Special dilations of skin, like the pouch of a pelican, or the air sacs of a prairie-hen, may be moderately displayed. §40. Tun skin. Loose prumace. It is astonishing how much resistance is offered by the thin skin of the smallest bird. Though no thicker than tissue paper, it is not very liable to tear if deftly handled; yet a rent once started often enlarges to an embarrassing extent if the skin be stretched in the least. Accidental rents, and enlargements of shot-holes, should be neatly sewn up, if occurring in an exposed place; but in most cases the plumage may be set to hide the openings. The tro- gons are said to have remarkably thin and delicate skin; I have never handled one in the flesh. Among our birds, the cardinal grosbeak has, I think, about the tenderest skin. The obvious indication in all such cases is simply a little extra delicacy of manipulation. In skinning most birds, you should not loose more than a feather or two, excepting those loos- ened by the shot. Pigeons are peculiar, among our birds, for the very loose insertion of their plumage; you will have to be particularly careful with them and in spite of all your precautions a good many feathers will probably drop. Strip- ping down the secondary quills from the forearm, in the manner already indicated, will so almost invariably set these feathers free from the skin that I recommend you not to attempt it, but to dress the wings as prescribed for large birds. §41. Fatness. Fat is a substance abhorred of all dissec- tors; always in the way, embarrassing operations and obscur- ing observations, while it is seldom worth examination after its structure has once been ascertained. It is particularly obnoxious to the taxidermist, since it is liable to soil the plu- mage during skinning, and also to soak into the feathers after- wards; and greasy birdskins are never pleasing objects. A 76 HOW TO MAKE A BIRDSKIN. few birds never seem to have any fat; some, like petrels, are always oily ; at times, especially in the indolent autumn season, when birds have little to do but feed, the great majority ac- quire an embonpoint doubtless to their own satisfaction, but to the taxidermist’s discomfort. In all such cases, gypsum should be lavishly employed. Strew plaster plentifully from the first cut, all through the operation ; dip your fingers in it frequently, as well.as your instruments. The invaluable absorbent will deal with most of the ‘‘ running” fat. When the skin is com- pletely reversed remove as much of the solid fat as possible ; it is generally found occupying the areolar tissue of particular definite tracts, and most of it may usually be peeled or flaked off in considerable masses. Since the soft and oozy state of most birds’ fat at ordinary temperatures may be much im- proved by cold, it will repay you to leave your birds on ice for a while before skinning, if you have the means and time to do so; the fat will become quite firm. There is a device for preventing or at any rate lessening the soiling of the plumage so apt to occur along the line of your incision; it is invaluable in all cases of white plumage. Take a strip of cloth of greater width than the length of the feathers, long enough to go up one side of the cut and down the other. Sew this closely to the skin all around the cut, and it will form an apron to guard the plumage. You will too frequently find that a bird, pre- pared without soiling and laid away apparently safe, after- wards grows greasy; if the plumage is white, it soon becomes worse than ever by showing dust that ‘the grease catches. Perhaps the majority of such birds in our museums show the dirty streak along the belly. The reason is, that the grease has oozed out along the cut and wherever else the skin has been broken, and infiltrated the plumage, being drawn up ap- parently by capillary attraction, just as a lampwick “sucks up” oil. Sometimes, without obviously soiling the plumage, the grease will run along the thread that ties the label, and make a uniformly transparent piece of ‘‘oil-paper.” I have no remedy to offer for this gradual infiltration of the plumage. It will not wash out, even with soap and water. Possibly BLOODSTAINS, ETC. 717 careful and persistent treatment with an ether might be effec- tive, but I am not prepared to say it would be. Removal of all fat that can be got off during skinning with a liberal use of plaster will in a measure prevent a difficulty that remains incurable. $42. Broopstains, Etc. In the nature of the case, this com- plication is of continual occurrence; fortunately it is easier dealt with than greasiness. Much may be done, in the field, to prevent bloodying of the plumage, as already said. A little blood does not show much on a dark plumage; but it is of course conspicuous on light or white feathers. Dried blood may often be scraped off, in imitation of the natural process by which a bird cleanses its plumage with the bill; or be pul- verized by gently twiddling the feathers between the fingers, and then blown off. But feathers may by due care be washed almost as readily as clothing; and we must ordinarily resort to this to remove all traces of blood, especially from white surfaces. If properly dried they do not show the operation. With a soft rag or pledget of cotton dipped in warm water bathe the place assiduously, pressing down pretty hard, only taking care to stroke the feathers the right way, so as not to crumple them, until the red color disappears; then you have simply a wet place to deal with. Press gypsum on the spot; it will cake; flake it off and apply more, till it will no longer stick. Then raise the feathers on a knife blade and sprinkle gypsum in among them; pat it down and shake it up, wrestling with the spot till the moisture is entirely absorbed. Two other fluids of the body will give you occasional annoy- ance—the juices of the alimentary canal, and the eye-water. Escape of the former by mouth, nostrils or vent is preventable by plugging these orifices, and its occurrence is inexcusable. But shot often lacerates the gullet, crop and bowels, and though nothing may flow at the time, subsequent jolting or pressure in the game bag causes the escape of fluids: a seemingly safe specimen may be unwrapped to show the whole belly plumage a sodden brown mass. Such accidents should be treated pre- 18 HOW TO MAKE A BIRDSKIN. cisely like bloodstains; but it is to be remarked that these stains are not seldom indelible, traces usually persisting in white plumage at least in spite of our best endeavors. Eye- water, insignificant as it may appear, is often a great annoy- ance, this liquor is slightly glairy, or rather glassy, and puts a sort of sizing on the plumage, difficult to efface —the more so since the soiling necessarily occurs in a conspicuous place, where the plumage is too scanty and delicate to bear much handling. It frequently happens that a lacerated eyeball, by the elasticity of the coats, or adhesion of the lids, retains its fluid till this is pressed out in manipulating the parts; and recollecting how the head lies buried in plumage at that stage of the process, it will be seen that not only the head, but much of the neck and eyen the breast may become wetted. If the parts are extensively soaked, the specimen is almost irrepa- rably damaged, if not ruined. Plaster will absorb the moist- ure, but much of the sizing may be retained on the plumage ; therefore, though the place seems simply wet, it should be thor- oughly washed with water before the gypsum is applied. I always endeayor to prevent the accident; if I notice a lacer- ated eyeball, I extract it before skinning, in the manner de- scribed for woodpeckers. Miscellaneous stains, from the juices of plants, etc., may be received; all such are treated on gen- eral principles. Blood on the beak and feet of rapacious birds, mud on the bill and legs of waders, etc., etc., may be washed off without the slightest difficulty. A land bird that has fallen in the water should be recovered as soon as possible, picked up by the bill, and shaken; most of the water will run off, un- less the plumage is completely soaked. It should be allowed to dry just as it is, without touching the plumage, before being wrapped and bagged. ‘If a bird fall in soft mud, the dirt should be scraped or snapped off as far as this can be done without plastering the feathers down, and the rest allowed to dry ; it may afterward be rubbed fine and dusted off, when no harm will ensue, except to white feathers which may require washing. MUTILATION. 19 $43. Murmarron. You will often be troubled, early in your practice, with broken legs and wings, and various lacerations ; but the injury must be very severe (such as the carrying away of a limb, or blowing off the whole top of a head) that can- not be in great measure remedied by care and skill. Sup- pose a little bird, shot through the neck or small of the back, comes apart while being skinned ; you have only to remove the hinder portion, be that much or little, and go on with the rest as if it were the whole. If the leg bone of a small bird be broken near the heel, let it come away altogether—it will make little if any difference. In case of the same accident to a large bird that ought to have the légs wrapped, whittle out a peg and stick it in the hollow stump of the bone; if there is no stump left file a piece of stout wire to a point and stick it into the heel joint. If the forearm bone that you usually leave in a small bird is broken, remove it and leave the other in; if both are broken, do not clean the wings so thoroughly that they become detached; an extra pinch of arsenic will condone the omission. In a large bird, if both bones of the forearm are broken, splint them with a bit of wood laid in between so that one end hitches at the elbow, the other at the wrist. A humerus may be replaced like a leg bone, but this is rarely required. If the skull be smashed, save the pieces, and leave them if you can; if not, imitate the arch of the head with a firm cotton-ball. A broken tarsus is readily splinted with a pin thrust up through the sole of the foot: if too large for this, use a pointed piece of wire. There is no mending a bill when part of it is shot away, for I think the replacing of part by putty, stucco, etc., inadmissible; but if it be only frac- tured, the pieces may usually be retained in place by winding with thread, or with a touch of glue or mucilage. It is singu- lar, by the way, what unsightliness results from a very trifling injury to the bill—much, I suppose, as a boil on a person’s nose is peculiarly deplorable. I have already hinted how art- fully various weak places in a skin, due to mutilation or loss of plumage, may be hidden. 80 HOW TO MAKE A BIRDSKIN. §44. Decomeosition. It might seem unnecessary to speak of what may be smelled out so readily as animal putrescence, but there are some useful points to be learned in this connec- tion, besides the important sanitary precautions that are to be deduced. Immediately after death the various fluids of the body begin to ‘‘settle” (so to speak) and shortly after, the muscular system as a rule becomes fixed in what is technically called rigor mortis. This stiffening usually occurs as the ani- mal heat dies away; but its onset, and especially its duration, is very variable, according to circumstances, such as cause of death ; although in most cases of sudden violent death of an animal in previous good health, it seems to depend chiefly upon temperature, being transient and imperfect, or altogether want- ing in hot weather. As it passes off, the whole system re- laxes, and the body soon becomes as ‘“‘limp” as at the moment of death. This is the period immediately preceding decompo- sition —in-fact, it may be considered as the stage of incipient putridity ; it is very brief in warm weather; and it should be seized as the last opportunity of preparing a bird without inconvenience and even danger. If not skinned at once, putrescence becomes established ; it is indicated by the efflu- vim (at the outset “sour,” but rapidly acquiring a variety of disgusting odors); by the distension of the abdomen with gaseous products of decomposition; by a loosening of the cuticle, and consequently of the feathers; and by other signs. If you part the feathers of a bad-smelling bird’s belly to find the skin swollen and livid or greenish, while the feathers come off at a touch, the bird is too far gone to be recovered without trouble and risk that no ordinary specimen warrants. It is a singular fact that this early putrescence is more poisonous than utter rottenness; as physicians are aware, a post-mortem examination at this stage, or even before it, in- volves more risk than their ordinary dissecting-room expe- rience. It seems that both natural and pathological poisons lose their early virulence by resolution into other products of decay. The obvious deduction from all this is to skin your birds soon enough. Some say they are best skinned per- DECOMPOSITION. 81 - fectly fresh, but I see no reason for this; when I have time to choose, I take the period of rigidity as being preferable on the whole; for the fluids have then “ settled,” and the limbs are readily relaxed by manipulation. If you have a large bag to dispose of, and are pressed for time, set them in the coolest place you can find, preferably on ice; a slight lowerjng of temperature may make a decided difference. Disembowelling, which may be accomplished in a moment, will materially retard decomposition. Injections of creosote or dilute carbolic acid will arrest decay for a time, for an indefinitely long period if a large quantity of these antiseptics be employed. When it becomes desirable (it can never be necessary) to skin a putres- cent bird, great care must be exercised not only to accomplish the operation, but to avoid danger. I must not, however, un- consciously lead you to exaggerate the risk, and will add that I think it often overrated. I have probably skinned birds as ‘‘ camey” as any one has, and repeatedly, without being con- scious of any ill effects. J am sure that no poison, ordinarily generated by decomposition of a body healthy at death, can compare in virulence with that commonly resulting after death by many diseases. I also believe that the gaseous products, however offensive to the smell, are innocuous as arule. The danger practically narrows down to the absorption of fluids through an abraded surface; the poison is rarely taken in by natural pores of healthy skin, if it remain in contact but a short time. Cuts and scratches may be closed with a film of collodion, or covered with isinglass or court plaster, or pro- tected by rubber cots on the fingers. The hands should, of course, be washed with particular care immediately after the operation, and the nails scrupulously dressed. Having never been poisoned (to my knowledge), I cannot give the symptoms from personal experience ; but I will quote from Mr. Maynard. ‘‘In a few days numerous pimples, which are exceedingly painful, appear upon the skin of the face and other parts of the person and, upon those parts where there is chafing or rub- bing, become large and deep sores. There is a general languor and, if badly poisoned, complete prostration results ; the slight- MANUAL. 6F 82 HOW TO MAKE A BIRDSKIN. est scratch becomes a festering sore. Once poisoned in this manner (and I speak from experience), one is never afterward able to skin any animal that has become in the least putrid, without experiencing some of the symptoms above described. Even birds that you handled before with impunity, you cannot now skin without great care. The best remedy in this case is, as the Hibernian would say, not to get poisoned, . . bathe the parts frequently in cold water ; and, if chafed, sprinkle the parts after bathing, with wheat flour. These remedies, if persisted in, will effect a cure, if not too bad; then, medical advice should be procured without delay.”* fe §45. How ro mounT BirpDs. As some may not improbably procure this volume with a reasonable expectation of being taught to mount birds, I append the required instructions, although the work only professes to treat of the preparation of skins for the cabinet. Asa rule, the purposes of science are best subserved by not mounting specimens; for display, the only end attained, is not required. I would strongly advise you not to mount your rarer or otherwise particularly, valuable specimens ; select for this purpose nice, pretty birds of no special scientific value. The principal objections to mounted birds are, that they take up altogether too much room, require special arrangements for keeping and transportation, and can- not be handled for study with impunity. Some might suppose that a mounted bird would give a better idea of its figure and general aspect than a skin; but this is only true to a limited extent. Faultless mounting is an art really difficult, acquired by few; the average work done in this line shows something of caricature, ludicrous or repulsive, as the case may be. To: copy nature faithfully by taxidermy requires not only long and close study, but an artistic sense; and this last is a rare * Avoid all mechanical irritation of the inflamed parts; touch the parts that have ulcerated with a stick of lunar caustic; take a dose of salts; use syrup of the iodide of iron, or tincture of the chloride of iron, say thirty drops of either, in a wineglass of water, thrice daily; rest at first, exercise gradually as you can bear it; and skin no birds till you have completely recovered. MOUNTING BIRDS. 83 gift. Unless you have at least the germs of the faculty in your composition your taxidermal success will be incommensu- rate with the time and trouble you bestow. My own taxider- mal art is of a low order, decidedly not above average ; although I have mounted a great many birds that would look well enough by the side of ordinary museum work, few of them ~ have entirely answered my ideas. A live bird is to me such a beautiful object that the slightest taxidermal flaw in the effort to represent it is painfully offensive; perhaps this makes me ' place the standard of excellence too high for practical pur- poses. I like a good honest birdskin that does not pretend to be anything else; it is far preferable to the ordinary taxider- mal abortions of the show-cases. But if, after the warnings that I mean to convey in this paragraph, you still wish to try your hand in the higher department of taxidermy, I will ex- plain the whole process as far as manipulation goes; the art you must discover in yourself. The operation of skinning is precisely the same as that already given in detail; then, instead of stuffing the skin as directed above, to lie on its back in a drawer, you have to stuff it so that it will stand up on its feet and look as much like a live bird as possible. ‘To this end a few additional implements and materials are required. ‘These are:—a, annealed wire of various numbers; it may be iron or brass, but must be perfectly annealed, so as to retain no elasticity or “ spring ;” 6, several files of different sizes; c, some slender, straight’ brad awls; d, cutting pliers; e, setting needles, merely sew- ing or darning needles stuck in a light wooden handle, for dressing individual feathers; jf, plenty of pins* and sewing thread; g, an assortment of glass eyes. (The fixtures and decorations are noticed, beyond, as occasion for their use arises.) There are two principal methods of mounting, which may _be respectively styled soft stuffing, and hard stuffing. In the former, a wire framework, consisting of a single anterior * The long, slender insect pins used by entomologists are the best. 84 HOW TO MAKE A BIRDSKIN. piece passing in the middle line of the body up through the neck and out at the top of the head, is immovably joined behind with two pieces, one passing through each leg: around this naked forked frame soft stuffing is introduced, bit by bit, till the proper contour of the skin is secured. I have seen very pretty work of this kind, particularly on small birds; but I consider it much more difficult to secure satisfactory results in this way than by hard stuffing, and I shall therefore con- fine attention to the latter. This method is applicable to all birds, is readily practised, facilitates setting of the wings, arranging of the plumage, and giving of any desired attitude. In hard stuffing, you make a firm ball of tow rolled upon a wire of the size and shape of the bird’s body and neck to- gether; you introduce this whole, afterwards running in the leg wires and clinching them immovably in the mass of tow. Having your empty skin in good shape, as already described, cut three pieces of wire of the right* size; one piece some- what longer than the whole bird, the other pieces two or three times as long as the whole leg of the bird. File one end of each piece to a fine sharp point, try to secure a three-edged cutting point like that of surgical needles, rather than the smooth, punching point of a sewing needle, the former perfo- rates more readily. Have these wires perfectly straight. Bend a small portion of the unfiled end of the longer wire ir- . regularly upon itself, as a convenient nucleus for the ball of tow.{ Take fine clean tow, in loose dossils, and wrap it round and round the wire nucleus, till you make a firm ball, of the size and shape of the bird’s body and neck. Study the con- tour of the skinned body: notice the swelling breast muscles, the arch of the lower back, the hollow between the furcula into *The right size is the smallest that will support the whole weight of the stuff- ing and skin without bending, when a piece is introduced into each leg. If using too thick wire you may have trouble in thrusting it through the legs, or may burst the tarsal envelope. +If accidentally kinky, the finer sizes of wire may be readily straightened by drawing strongly upon them s0 as to stretch them a little. Heavier wire musf be hammered out straight. t Cotton will not do at all; it is too soft and elastic, and moreover will not allow of the leg wires being thrust into it and there clinched. STUFFING AND WIRING. 85 which the neck, when naturally curved, sinks. Everything depends upon correct shaping of the artificial body; if it be misshapen, no art can properly adjust the skin overit. Firm- ness of the tow ball and accurate contour may both be secured by wrapping the mass with sewing thread, loosening here, tightening there, till the shape is satisfactory. Be particular to secure a smooth superficies ; the skin in drying will shrink close to the stuffing, disclosing its irregularities, if there be any, by the maladjustment of the plumage that will ensue. Observe especially that the neck, though the direct continua- tion of the backbone, dips at its lower end into the hollow of the merrythought, and so virtually begins there instead of directly between the shoulders. The three mistakes most likely to be made by a beginner are, getting the body altogether too large, not firm enough, and irregular. When properly made it will closely resemble the bird’s body and neck, with an inch or several inches of sharp-pointed wire pro- truding from the anterior extremity of the neck of tow. You have now to introduce the whole affair into the skin. With the birdskin on its back, the tail pointing to your right elbow, and the abdominal opening as wide as possible, hold the body in position relative to the skin; enter the wire, pass it up through the neck, bring the sharp point exactly against the middle of the skull, pierce skull and skin, causing the wire to protrude some distance from the middle of the crown. Then by gentle means insinuate the body, partly pushing it in, partly drawing the skin over it, till it rests in its proper position. This is just like drawing on a tight kid glove, and no more difficult. See that the body is completely encased ; you must be able to close the abdominal aperture entirely. You haye next to wire the legs. Enter the sharp point of one of the leg wires already prepared, exactly at the centre of the sole of the foot, thrusting it up inside the tarsal en- velope the whole length of the ‘“‘shank,” thence across the heel-joint * and up along the next bone of the leg, still inside * There is occasionally difficulty in getting the wire across this joint, from the point sticking into the enlarged end of the shin-bone. In such case, take stout 86 HOW TO MAKE A BIRDSKIN. the skin. The point of the wire will then be seen within the skin and may be seized and drawn a little further through, and you will have passed a wire entirely out of sight all the way along the leg. The end of the wire is next to be fixed immovably in the tow ball. Thrust it in at the point where the knee, in life, rests. against the side of the body.* Bring the point to view, bend it over and reinsert it till it sticks fast. There are no special directions to be given here; fasten the wire in any way that effectually prevents ‘“ wabbling.” You may find it convenient to wire both legs before fasten- ing either, and then clinch them by twisting the two ends together. But remember that the leg wires may be fixed re- specting each other, yet permit a see-saw motion of the body upon them. This must not be, the body and legs must be fixed upon a jointless frame. Having secured the legs, close the abdominal opening nicely, either by sewing or pinning, you may stick pins in anywhere, as freely as in a pin cushion; the feathers hide their heads. Stick a pin through the pope’s nose, to fix the tail in place. All this while the bird has been lying on its back, the neck stretched straight in continuation of the body, wired stiffly, the legs straddling wide apart, straight and stiff, the wings lying loosely, half-spread. Now bring the legs together, paral- lel with each other, and make the sharp bend at the heel joint that will bring the feet naturally under the belly (over it as the bird lies on its back). Pick up the bird by the wires that project from the soles and set it on its stand, by running the wires through holes bored the proper distance apart, and then securing the ends by twisting. The temporary stand that you use for this purpose should have a heavy or otherwise firm sup- port, so as not easily to overturn during the subsequent manip- ulations. At this stage the bird is a sorry looking object; but pliers and pinch the joint till the bone is smashed to fragments. The wire will then pass and the comminution will not show. If there is any trouble in passing the wire through the tarsus, bore a hole for it with a brad awl. *This point is further forward and more belly-ward than you might suppose. Observe the skinned body again, and see where the lower end of the thigh lies. If you insert the wire too far back, you cannot by any possibility balance the bird naturally on its perch; it will look in imminent danger of toppling over. SETTING THE BIRD. 87 if you have stuffed correctly and wired securely, it will soon improve. Begin by making it stand properly. The common fault here is placing the tarsi too nearly perpendicular. Perch- ing birds, constituting the majority, habitually stand with the tarsi more nearly horizontal than perpendicular, and generally keep the tarsi parallel with each other. Wading and most walking birds stand with the legs more nearly upright and straight. Many swimming birds straddle a little; others rarely if ever. See that the toes clasp the perch naturally, or . are properly spread on the flat surface. Cause the flank feath- ers to be correctly adjusted over the tibiz (and here I will remark that with most birds little, if any, of the tibize shows in life) the heel joint barely, if at all, projecting from the gen- eral plumage. It is a common fault of stuffing not to draw the legs closely enough to the body. Above all, look out for the centre of gravity ; though you have really fastened the bird to its perch, you must not let it look as if it would fall off if the wires slipped; it must appear to rest there of its own accord. Next, give the-head and neck a preliminary setting, according to the attitude you have determined upon. This will bring the plumage about the shoulders in proper position for the setting of the wings, to which you may at once attend. If the body be correctly fashioned and the skin of the shoulders only ad- justed over it, the wings will fold into place without the slight- est difficulty. All that I have said before about setting the wings in a skin applies here as well; but in this case they will not stay in place since they fall by their own weight. They must be pinned up. Holding the wing in place thrust a pin steadily through, near the wrist joint, into the tow body. ' Sometimes another pin is required to support the weight of the primaries; it may be stuck into the flank of the bird, the - outer quill feather resting directly upon it. With large birds - a sharp pointed wire must replace the pin. When properly set the wing tips will fall together or symmetrically opposite each other, the quills and coverts will be smoothly imbricated, the scapular series of feathers will lie close, and no bare space will show in front of the shoulder. Much depends upon the 88 HOW TO MAKE A BIRDSKIN. jinal adjustment of the head. The commonest mistake is get- ting it too far away from the body. In the ordinary attitudes of most birds, little neck shows, the head appearing nestled upon the shoulders. If the neck appears too long, it is not to be contracted by pushing the head directly down upon it, but by making an S curve of the neck. No precise direc- tions can be given for the set of the head but you may be assured it is a delicate, difficult matter; the slightest turn of the bill one way or another may alter the whole expression of the bird. You will of course have determined beforehand upon your attitude—upon what you wish the bird to appear to be doing; then, let your meaning be pointed by the bird’s bill. On the general subject of striking an attitude, and giving expression to a stuffed bird, little can be said to good purpose. If you are to become proficient in this art, it will come from your own study of birds in the field, your own good taste and appreciation of bird life. ‘The manual processes are easily described and practised —it is easy to grind pnint, I suppose, but not so to be an artist. I shall therefore only follow the above account of the general processes with some special practical points. After ‘‘attitudinizing” to your satisfaction, or to the best of your ability, the plumage is to be carefully ‘‘ dressed.” Feathers awry may be set in place with a light spring forceps, or needles fixed in a handle—one by one if necessary. When no individual feather seems out of place, it often occurs that the general plumage has a loose, slovenly aspect. This is readily corrected by wrapping with fine thread. Stick a pin into the middle of the back, another into the breast, and perhaps others elsewhere. Fasten the end of a spool of sewing cotton to one of the pins, and carry it to another, winding the thread about among the pins, till the whole surface is covered with an irregular network. Tighten to reduce an undue prominence, loosen over a depression ; but let the wrap- ping as a whole be light, firm and even. This procedure, nicely executed, will give a smoothness to the plumage not otherwise attainable, and may be made to produce the most exquisite SPREADING TAILS, ETC. 89 curves particularly about the head, neck and breast. The thread should be left on till the bird is perfectly dry; it may then be unwound or cut off, and the pins withdrawn. When a particular patch of skin is out of place, it may often be pulled into position and pinned there. You need not be afraid of sticking pins in anywhere; they may be buried in the plumage and left there, or withdrawn when the skin is dry. Tn addition to the main stuffing, a little is often required in particular places. As for the legs, they should be filled out in all such cases as I indicated earlier in this chapter; small birds require no such stuffing. It is necessary to fill out the eyes so that the lids rest naturally ; it may be done as hereto- fore directed, or by putting in pledgets of cotton from the out- side. A little nice stuffing is generally required about the upper throat. To stuff a bird with spread wings requires a special process, in most cases. The wings are to be wired, exactly as directed for the legs; they may then be placed in any shape. But with most small birds, and those with short wings, simple pinning in the half spread position indicating fluttering will suffice; it is readily accomplished with a long, slender insect pin. I have already spoken of fixing the tail by pinning or wiring the pope’s nose to the tow body; it may be thus fixed at any desired elevation or depression. There are two ways of spreading the tail. One is torun a pointed wire through the quills, near their base, where the wire will be hidden by the coverts ; each feather may be set at any required - distance from the next by sliding it along this wire. This method is applicable to large birds; for small ones the tail may be fixed with the desired spread by enclosing it near its base, in a split match, or two slips of card-board, with the ends tied together. This holds the feathers until they dry in posi- tion, when it is to be taken off. Crests may be raised, spread and displayed on similar principles. A small crest, like that of a cardinal or cherry bird, for instance, may be held up till it dries in position by sticking in behind it a pin with a little ball of cotton on its head. It is sometimes necessary to make a bird’s toes grasp a support by tying them down to it till they 90 HOW TO MAKE A BIRDSKIN. dry. The toes of waders that do not lie evenly on the surface of the stand may be tacked down with small brads. The bill may be pinned open or shut, as desired, by the method already given. Never paint or varnish a bird’s bill or feet. Substitution of an artificial eye for the natural one is essen- tial for the good looks of a specimen. Glass eyes, of all sizes and colors, may be purchased at a moderate cost. The pupil is always black; the iris varies. You will, of course, secure the proper color if it is known, but if not, put in a dark brown or black eye. It is well understood that this means nothing —it is purely conventional. Yellow is probably the next most com- mon color; then come red, white, blue and green, perhaps approximately in this order of frequency. But do not use these striking colors at hap-hazard, sacrificing truth perhaps, to looks. Eyes are generally inserted after the specimen is dry. Remove a portion of the cotton from the orbit, and moisten the lids till they are perfectly pliable; fix the eye in with putty or wet plaster of Paris, making sure that the lids are naturally adjusted over it. It goes in obliquely, like a button through a button-hole. Much art may be displayed in this little matter, making a bird look this way or that, to carry out the general ‘‘ expression.” On finishing a specimen, set it away to dry—the time re- quired varies, of course, with the weather, the size of the bird, its fatness, etc. The more slowly it dries, the better; there is less risk of the skin shrinking irregularly. You will often find that a specimen set away with smooth plumage and satisfac- tory curves dries more or less out of shape, perhaps with the feathers raised in places. I know of no remedy; it may, in a measure, be prevented by scrupulous care in making the body smooth and firm, and in securing slow, equable drying. When perfectly dry remove the wrapping, pull out the superfluous pins or wires, nip off the others so short that the ends are con- cealed, and insert the eyes. The specimen is then ready to be transferred to its permanent stand. Fixtures for the display of the object of course vary inter- minably. We will take the simplest case, of a large collection STANDS AND ORNAMENTAL SUPPORTS. 91 of mounted birds for public exhibition. In this instance, uni- formity and simplicity are desiderata. ‘Spread eagle” styles of mounting, artificial rocks and flowers, etc., are entirely out of place in a collection of any scientific pretensions, or de- signed for popular instruction. Besides, they take up too much room. Artistic grouping of an extensive collection is usually out of the question; and when this is unattainable, half-way efforts in that direction should be abandoned in favor of severe simplicity. Birds look best on the whole in uniform rows, as- sorted according to size, as far as a natural classification allows. They are best set on the plainest stands, with circular base and a short cylindrical crossbar lightly turned upright. The stands should be painted dead-white and be no larger than is necessary for secure support; a neat stiff paper label may be attached.* A small collection of birds, as an ornament to a private residence, offers a different case; here, variety of atti- tude and appropriate imitation of the birds’ natural surround- ings, are to be secured. A miniature tree, on which a number of birds may be placed, is readily made. Take stout. wire, and by bending it, and attaching other pieces, get the framework of the tree of the desired size, shape and number of perches. Wrap it closely with tow to a proper calibre, remembering that the two forks of a stem must be together only about as large as the stem itself. Gather a basket full of lichens and tree moss; reduce them to coarse powder by rubbing with the hands ; besmear the whole tree with mucilage or thin glue, and sift the lichen powder on it till the tow is completely hidden. This produces a very natural effect, which may be heightened by separately affixing larger scraps of lichen, or little bunches of moss; artificial leaves and flowers may be added at your taste. The groundwork may be similarly prepared with a bit of board, made adhesive and bestrewn with the same substance ; * A very simple and neat way of attaching the label to the stand is that used in the Peabody Academy of Science and other museums. It consists of narrow strips of tin bent over at each end so as to hold the label, and fixed to the stand by a small tack at any desired angle. These tins and neat red-lined labels can be had at the Naturalists’ Agency, or the printed names can be cut from the *“‘ Check List ” and used for labels for North American birds. 92 HOW TO MAKE A BIRDSKIN. grasses and moss may be added. If a flat surface is not de_. sired soak stout pasteboard, till it can be moulded in various irregular elevations and depressions ; lay it over the board and decorate it in the same way. Rocks may be thus nicely imi- tated, with the addition of powdered glass of various colors. Such a lot of birds is generally enclosed in a cylindrical glass case with arched top. As it stands on a table to be viewed from different points, it must be presentable on all sides. A niche in parlor or study is often fitted with a wall-case, which, when artistically arranged, has a very pleasing effect. As such cases may be of considerable size, there is opportunity for the display of great taste in grouping. A place is not to be found for a bird, but a bird for the place—waders and swimmers below on the ground, perchers on projecting rests above. The surroundings may be prepared by the methods just indicated. One point deserves attention here—since the birds are only viewed from the front, they may have a ‘‘show-side ” to which everything else may be sacrificed. Birds are represented flying in such eases more readily than under other circumstances — supported on a concealed wire inserted in the back of the case. I have seen some very successful attempts to represent a bird swimming, the duck being let down part way through an oval hole in a plate of thick glass, underneath which were fixed stuffed fishes, shells and seaweed. It is hardly necessary to add that in all ornamental collections, labels or other scien- tific machinery must be rigorously suppressed. Transportation of mounted birds offers obvious difficulty. Unless very small, they are best secured immovably inside a box by screwing the foot of the stands to the bottom and sides, so that they stay in place without touching each other. Or, they may be carefully packed in cotton, with or without re- moval of the stands. Their preservation from accidental injury depends ppon the same care that is bestowed upon ordi- nary fragile ornaments of the parlor. The ravages of insects are to be prevented upon the principles to be hereafter given in treating of the preservation of birdskins. : CHAPTER VII. MISCELLANEOUS PARTICULARS. §46. DETERMINATION OF SEX. This is an important matter, which must never be neglected. For although many birds show unequivocal sexual distinctions of size, shape and color, like those of the barnyard cock and hen for instance, yet the outward characteristics are more frequently obscure, if not altogether inappreciable on examination of the skin alone. Young birds, moreover, are usually indistinguishable as to sex, although the adults of the same species may be easily recog. nized. The rule results, that the sexual organs should be ex- amined, as the only infallible indices. The essential organs of masculinity are the festicles; similarly, the ovaries contain the essence of the female nature. However similar the accessory sexual structures may be, the testicles and ovaries are always distinct. The male organs of birds never leave the cavity of the belly to fill an external bag of skin (scrotum) as they do among mammalia, they remain within the abdomen, and lie in the same position as the ovaries of the female. Both these organs are situated in the belly opposite what corresponds to the ‘small of the back,” bound closely to the spine, resting on the front of the kidneys near their fore end. ‘The testicles are a pair of subspherical or rather ellipsoidal bodies, usually of the same size, shape and color; and are commonly of a dull opaque whitish tint. They always lie close together. A re- markable fact connected with them is, that they are not always of the same size in the same bird, being subject to periodical enlargement during the breeding season, and corresponding atrophy at other seasons. Thus the testicles of a house spar- row, no bigger than a pin’s head in winter, swell to the size of peas in April. The ovary (for although this organ is paired originally, only one is usually functionally developed in birds) will be recognized as a flattish mass of irregular contour, and usually whitish color; when inactive, it simply appears of finely granular structure which may require a hand lens to be made (93) 94 MISCELLANEOUS PARTICULARS. out; when producing eggs, its appearance is unmistakable. Both testis and ovary may further be recognized by a thread | leading to the end of the lower bowels—in one case the sperm- duct, in the other the oviduct; the latter is usually much the more conspicuous, as it at times transmits the perfect egg. There is no difficulty in reaching the site of these organs. Lay the bird on the right side, its belly toward you: cut with the ) scissors through the belly-walls diagonally from anus to the a root of the last rib—or further, snipping across a few of the lower ribs, if these continue far down, as they do in a loon for — instance. Press the whole mass of intestines aside collectively, a and you at once see to the small of the back. ‘There you ob- a serve the kidneys—large, lobular, dark reddish masses moulded into the concavity of the sacrum (or back middle bone of the pelvis) and on their surface, towards their fore end, lie testes or ovary, as just described. The only precaution required is, not to mistake for testicles a pair of small bodies capping the kidneys. These are the adrenals or ‘‘ supra-renal capsules ”— organs whose function is unknown, but with which at any rate we have nothing to do in this connection. They occur in both sexes, and if the testicles are not immediately seen, or the ovary not at once recognized, they might easily be mistaken for testicles. Observe that instead of lying in front, they cap the kidneys; that they are usually yellowish instead of opaque whitish ; and that they have not the firm, smooth, reg- ular sphericity of the testicles. The sex determined, use the sign ¢ or 9 to designate it, as already explained. In the very rare cases of impotence or sterility among birds, of course no organs will be observed; but Ishould dislike to become respon- sible for such labelling without very careful examination. The organs of a small bird out of the breeding season are never conspicuous, but may always be found on close scrutiny, unless the parts are disintegrated by a shot. $47. RECOGNITION OF AGE is a matter of ornithological ex- perience requiring in many or most cases great familiarity with birds for its even approximate accomplishment. There are, EXAMINATION OF THE STOMACH. 95 however, some unmistakable signs of immaturity, even after a bird has become full-feathered, that persist for at least one season. These are, in the first place, a peculiar soft fluffy “feel” of the plumage—the feathers lack a certain smooth- ness, density and stiffening which they subsequently acquire. Secondly, the bill and feet: are softer than those of the adults; the corners of the mouth are puffy and flabby, the edges and point of the bill are dull, and the scales, etc., of the legs are not sharply cut. Thirdly, the flesh itself is tender, and pale colored. These are some of the points common to all birds, and are independent of the special markings that belong to the youth of particular species. Some birds are actually larger for a while after leaving the nest, than in after years when the frame seems to shrink somewhat in acquiring the compactness of senility. On the other hand, the various members, espet cially the bill and feet, are proportionally smaller at first. Newly growing quills are usually recognized on sight, the barrel being dark colored and full of liquid, while the vanes are incomplete. In studying, for example, the shape of a wing or tail, there is always reason to suspect that the natural pro- portions are not yet presented, unless the quill is dry, colorless and empty, or only occupied with shrunken white pith. §48. EXAMINATION OF THE STOMACH frequently leads to inter- esting observations, and is always worth while. In the first place, we learn most unquestionably the nature of the bird’s food, which is a highly important item in its natural history. Secondly, we often secure valuable specimens in other depart- ments of zoology, particularly entomology. Birds consume incalculable numbers of insects, the harder kinds of which, such as beetles, are not seldom found intact in their stomachs ; and a due percentage of these represent rare and curious spe- cies. The gizzards of birds of prey, in particular, should always be inspected, in search of the small mammals, etc., they devour; and even if the creatures are unfit for preserva. tion, we at least learn of their occurrence, perhaps unknown before in a particular region. Mollusk-feeding and fish-eating 96 MISCELLANEOUS PARTICULARS. birds yield their share of specimens. The alimentary canal is often the seat of parasites of various kinds, interesting to the helminthologist ; other species are to be found under the skin, in the body of muscle, in the brain, etc. Most birds are also infested -with external parasites of many kinds, so various, that almost every leading species has its own sort of louse, tick, ete. Since these creatures are only at home with a live host, they will be found crawling on the surface of the plu- mage, preparing for departure, as soon as the body cools after death. There is in effect much to learn of a bird aside from what the prepared specimen teaches, and moreover apart from regular anatomical investigations. Whenever practicable, brief items should be recorded on the label, as already mentioned. §49. ResToRATION OF POOR SKINS. If your cabinet be a ‘‘oeneral”? one, comprising specimens from various sources, you will frequently happen to receive skins so badly prepared as to be unpleasant objects, besides failing to show their spe- cific characters. There is of course no supplying of missing parts or plumage; but if the defect be simply deformity, this may usually be in a measure remedied. The point is simply to relax the skin, and then proceed as if it were freshly removed from the bird; it is what bird stuffers constantly do, in mount- ing birds from prepared skins. The relaxation is effected by moisture alone. Remove the stuffing; fill the interior with cotton or tow saturated with water, yet not dripping: put pads of the same under the wings; wrap the bill and feet, and set the specimen in a damp cool place. Small birds soften very readily and completely ; the process may be facilitated by per- sistent manipulation. This is the usual method, but there is another, more thorough and more effective ; it is exposure to a vapor-bath. The appointments of the kitchen stove furnish all the apparatus required for an extempore ‘‘ steamer ;” the regu- lar fixture is a tin vessel much like a wash-boiler, with closed lid, false bottom and stopcock at lower edge. On the false bottom is placed a heavy layer of gypsum, completely satu- rated with water; the birds are laid on a perforated tray above ALCOHOLIC SPECIMENS. 97 it; and a gentle heat is maintained over a stove. The vapor penetrates every part of the skin, and completely relaxes it, without actually wetting the feathers. The time required varies oreatly of course; observation is the best guide. The chief precaution is not to let the thing get too hot. Professor Baird has remarked that crumpled or bent feathers may have much of their original elasticity restored by dipping in hot water. Im- mersion for a few seconds suffices, when the feathers will be ob- served to straighten out. Shaking off superfluous water; they may be simply left to dry or they may be dried with plaster. The method is chiefly applicable to the large feathers of the wings and tail. Soiled plumage of dried skins may be treated exactly as in the case of fresh skins. §50. Mummrrication. As before mentioned, decay may be arrested by injections of carbolic acid and other antiseptics ; if the tissues be sufficiently permeated with these substances, the body will keep indefinitely ; it dries and hardens, becoming, in short, a ‘“‘mummy.” Injection should be done by the mouth and yent, be thorough, and be repeated several times as the fluid dries in. It is an improvement on this to disembowel, and fill the belly with saturated tow or cotton. Due care should be taken not to soil the feathers in any case, nor should the carbolic solution come in contact with the hands, for it is a powerful irritant poison. I mention the process chiefly to con- demn it as an atrocious one; I cannot imagine what circum- stances would recommend it, while only an extreme emergency could justify it. It is further objectionable because it appears to lend a dingy hue to some plumages, and to dull most of them perceptibly. Birds prepared—rather unprepared —in this way, may be relaxed by the method just described, and then skinned ; but the operation is rather difficult. §51. Wer preparations. By this term is technically under- stood an object immersed in some preservative fluid. It is highly desirable to obtain more information of birds than their stuffed skins can ever furnish, and their structure cannot be MANUAL, 7 98 MISCELLANEOUS PARTICULARS. always examined by dissection on the spot. In fact, a certain small proportion of the birds of any protracted or otherwise ‘‘heavy” collecting may be preferably and very profitably pre- served in this way. Specimens in too poor plumage to be worth skinning may be thus utilized; so may the bodies of skinned birds, which, although necessarily defective, retain all the viscera, and also afford osteological material. Alcohol is the liquid usually employed and, of all the various articles recommended, seems to answer best on the whole. I have used a very weak solution of chloride of zinc with excellent results; it should not be strong enough to show the slightest turbidity. As glass bottles are liable to break when travelling, do not fit corners, and offer practical annoyance about corkage ; rectangular metal cans, preferably of copper, with screw-lid opening, are advisable. They are to be set in small, strong wooden boxes, made to leave a little room for the lid wrench, muslin bags for doing up separate parcels, parchment for labels, ete. Unoccupied space in the cans should be filled with tow or a similar substance, to prevent the specimens from swashing about. Labelling should be on parchment: the writ- ing should be perfectly dry before immersion: india-ink is the best. Skinned bodies should be numbered to correspond with the dried skin from which taken; otherwise they may not be identifiable. Large birds thrown in unskinned should have the belly opened, to let in the alcohol freely. Birds may be skinned, after being in alcohol, by simply drying them: they often make fair specimens. They are best withdrawn by the bill, that the “‘swash” of the alcohol at the moment of emer- sion may set the plumage all one way, and hung up to dry, untouched. Watery moisture that may remain after evapora- tion of the alcohol may be dried with plaster. §52. OsTEOLOGICAL PREPARATIONS. While complete skele- tonizing of a bird is a special art of some difficulty, and one that does not fall within the scope of this treatise, I may prop- erly mention two bony preparations very readily made, and susceptible of rendering ornithology essential service. I refer SKULLS AND BREAST BONES. 99 to the skull, and to the breast bone with its principal attach- ments. These parts of the skeleton are, as a rule, so highly characteristic that they afford in most cases invaluable zoo- logical items. To save a skull is of course to sacrifice a skin, to all intents; but you often have mutilated or decayed speci- mens that are very profitably utilized in this way. The breast bone, excepting when mutilated, is always preservable with the skin, and for ‘‘ choice” invoices may form its natural ac- companiment. You want to remove along with it the cora- coids (the stout bones connecting the breast bone with the shoulders), the merrythought intervening between these bones, and the shoulder-blades, all without detachment from each other. Slice off the large breast muscles close to the bone; and divide their insertions with the wing bones, scrape or cut away the muscles that tie the shoulder-blades to the chest ; snip off the ribs close to the side of the breast bone; sever a tough membrane usually found between the prongs of the wish- bone; then, by taking hold of the shoulders, you can lift out the whole affair, dividing some slight connections underneath the bone and behind it. The following points require atten- tion: the breast bone often has long slender processes behind and on the sides (the common fowl is one of the extreme illus- trations of this) liable to be cut by mistake for ribs, or to be snapped: the shoulder-blades usually taper to a point, easily broken off; the merrythought is sometimes very delicate, or defective. When travelling, it is generally not advisable to make perfect preparations of either skull or sternum: they are best dried with only superfluous flesh removed, and besprin- kled with arsenic. The skull, if perfectly cleaned, is particu- larly liable to lose the odd-shaped pronged bones that hinge the jaw, and the freely movable pair that push on the palate from behind. Great care should be exercised respecting the identification of these bones, particularly the sternum, which should invariably bear the number of the specimen to which it belongs. A skull is more likely to be able to speak for itself, and besides, is not usually accompanied by a skin; neverthe- less, any record tending to facilitate its recognition should be 100 MISCELLANEOUS PARTICULARS. duly entered on the register. There are methods, with which I am not familiar, of making elegant bony preparations. You may secure very good results by simply boiling the bones or, what is perhaps better, macerating them in water till the flesh is completely rotted away, and then bleaching them in the sun. A little potassa or soda hastens the process. With breast bones, if you can stop the process just when the flesh is completely dissolved but the tougher ligaments remain, you secure a ‘‘natural” preparation, as it is called; if the liga- ments go too, the associate parts of a large specimen may be — wired together, those of a small one glued. I think it best, with skulls, to clean them entirely of ligament as well as muscle; for the underneath parts are usually those conveying the most desirable information, and they should not be in the slightest degree obscured. Since in such case the anvil-shaped bones, the palatal cylinders already mentioned, and sometimes — other portions come apart, the whole are best kept in a suitable box. I prefer to see a skull with the sheath of the beak re- moved, though in some cases, particularly of hard billed birds, it may profitably be left on. The completed preparations should be fully labelled, by writing on the bone, in preference to an accompanying or attached paper slip, which may be lost. Some object to this, as others do to writing on eggs, thatit — ‘“‘defaces” the specimen; but I confess I see in dry bones no — beauty but that of utility.* 7 $53.
