INTRODUCTION. Tue great need of a good illustrated work to guide young naturalists in collecting and preserving objects of natural history has induced me to prepare the present Manual. In this attempt I hope I have been in some degree successful. I have spared no pains to bring to- gether, in a comprehensive form, the results of many years of experience in collecting and preserving objects of natu- ral history, both for private cabinets and for scientific museums. No popular work of this kind has before been published in America. Throughout the present work I have endeav- ored to encourage the young to engage in the ennobling study of Natural History, and to join the band of young naturalists so rapidly increasing in our land. I trust the reader will not by any means keep the teach- ings of this book secret, as some taxidermists are wont to counsel, but spread it broadcast among those who would profit by the information I have herein attempted to con- vey. It is intended for the Narurauist, whoever and wherever he may be; and as it comes from a colaborer in the common field, it will, perhaps, be well received. iv INTRODUCTION. All of Part First is original. In preparing objects of natural history I have in a great degree invented methods of my own, and have not given in this work a single one that I have not tested and proved equal to all oth- ers, if not superior. To avoid confusion, I have given only the method which experience has taught me to be the best. In this connection my thanks are due to Mr. E. L. Weeks, whose excellent illustrations will be found to add greatly to the value of the work. In Part. Second I have thought proper to add a cata- logue of the birds of Eastern Massachusetts, with notes, as tending to enable the collector to obtain the’ rarer spe- cies more readily, by specifying the localities and peculiar haunts in which they have been found by others. The critical notes may, perhaps, be perused with interest by the more experienced ornithologist. CONTENTS. — PART: I. CHARI Reg Le COLLECTING AND PRESERVING BIRDS, Scr. Pac I.

Draw the skin over the head, cutting off the ears close to the skull. Use caution in cutting the skin from the eyelids and in severing the lips frorn the skull, so as not to in- jure their outward appearance. The skull is to be detached entirely. Cover the inside of the skin well with arsenic, and, if large, rub it in well with the hand; but be sure that every part is poisoned. If there is any blood upon the hair, after the skin is turned into its former position, if it is dry, remove it with the stiff brush; if wet or very bloody, wash and dry with plaster, as explained in birds. Wind the leg-bones with sufficient hemp or cotton to supply the place of the muscles; then fill out the head, neck, and the rest of the body to their natural size. Sew up the orifice through which the body was removed neatly over and over, drawing the edges of the skin together nicely. Label the skin by sewing a bit of card-board upon one of the feet, or, if the animal is large, upon the ear, with the number of the specimen and the sex marked upon it. Clean the skull as much as possible with the scalpel ; if it is a large animal, the brains may be removed through the orifice where the spinal cord enters the skull. If this opening is not large enough to remove them, they should be left in. Roll the skull in arsenic, then label it with a number corresponding to the one upon the skin, and lay it by for future cleaning. The arsenic prevents insects from attacking it. Place the skin, if a small one, upon its side, with the legs bent neatly ; if a large one, upon its breast, with the Jegs stretched out on each side, the forelegs pointing for- ward, the hind ones backward. This is what is technically called a “ mammal’s skin.” COLLECTING AND PRESERVING MAMMALS. 49 Very large animals, such as Deer or Bears, should not be filled out in this way, but placed flat. In skinning large animals, make an incision in the form of a double cross, by making a longitudinal cut between the hind legs, from the root of the tail to the breast, between the forelegs ; then a transverse cut from the knee of the foreleg down the inside of the leg to the opposite knee. The same operation is repeated upon the hind legs. Then proceed as before, only, when the skin has been removed from the flanks, the animal must be suspended to facilitate the re- moval of the rest. In skinning a mammal with horns, make a longitudinal incision from the back of the neck to the occiput, or back of the head ; then make a transverse cut across the head, commencing about four inches beyond the right horn, and ending about four inches. to the left of the left horn, the cut passing close to the base of the horns, thus forming a T. Remove the skin from the body as far as the neck, which is cut at its junction with the body. The skull, horns, and neck are drawn through the above-mentioned orifice. In skinning large animals, it is well to take the diameter of the eye before it is removed, so that an artificial one may be inserted of the same size,-if the animal is to be mounted, as the eyelids shrink very much while drying. All mammals should be skinned as soon as possible after they are killed, especially small ones, as in a few hours decomposition will commence ; then the hair will come out. While skinning the legs of ruminants, such as Deer, . Sheep, ete., it will be found that the skin cannot be drawn over the knee-joint ; then cut longitudinally through the skin below the knee, and after severing the bone at the hoof and knee, remove it through this incision. The in- cision should be about one fourth the length of the dis- tance from the knee to the hoof. Bats are to be skinned in the ordinary manner, remoy- 3 D 50 THE NATURALIST’S GUIDE. ing the skin even to the tip of the phalanges of the wings; then tie the wing-hones together, as explained in birds. Place the bat upon a flat board to dry, and pin its wings in the proper position for flight. When dry, stitch it upon a piece of card-board. While skinning mammals, it is sometimes necessary to use plaster to absorb the blood and other juices that are apt to flow ; but if care is taken not to cut the inner skin over the abdomen it will not be needed. It is also some- times necessary to plug the mouth and nostrils, especially if blood flows from them. Srction III. Mounting Mammals. — The art of mount- ing mammals in lifelike attitudes can only be acquired by. experience. Hence the learner must practise the utmost degree of patience and perseverance. As in the first chapter I earnestly advised those who would be perfect to study nature, I would here repeat that advice. And if necessary while endeavoring to mount a bird, where the feathers cover the minor defects, it is essentially much more of a necessity to study nature carefully while striv- ing to imitate the graceful attitudes and delicately formed limbs of the smaller species of mammalia, or the full rounded muscles and imposing attitudes of the larger ones ; for in mammals the thin coat of hair will tend rather to expose than hide the most minute imperfections. Perfectly stuffed specimens can only be obtained by care- ful measurements of all the parts, such as the size of the legs, body, ete. In skinning mammals to mount, it is best not to remove the skull. Open it on the occipital bone, so as to remove the brains ; clean well; cover with arsenic; then supply the muscles removed, by using hemp wound tightly on with thread. As the skin will shrink badly if it is stuffed loosely, carefully fill out the space occupied by the mus- cles of the legs in the same manner. Cut wires for the THE WAY TO MOUNT MAMMALS. 51 feet, head, and tail, sharpen them on one end as directed in mounting birds ; now roll up grass until it is not quite as large round as the body, and about one third as long. Fill the fore part of the skin with bran or cut hemp as far back as the shoulders, and place the ball of grass against this filling, inside the skin. Now force the wires through the soles of the feet and top of the head into this ball; clinch them firmly. After filling the skin of the tail with bran, force the wire through the grass ball to the very end ; then clinch the opposite end in the ball by cutting off the part that protrudes and turning it in. Fill the remaining parts of the skin with bran to the natural size, and sew up the orifice carefully ; place the animal in the proper position by passing the protruding wires of the feet through holes in a board, clinching them firmly on the under side. The skin may now be moulded into shape with the hands, the hair carefully smoothed, the eyes set in the head with putty, the protruding wires cut off, and the specimen set away to dry. There are but few rules to be followed in placing animals in posi- tion, because they are almost infinite in variety. The most imperative rule applies to the positions of the legs, which are almost always the same ; and it should be studied with particular care, as a slight deviation from it will impair the lifelike attitude of the specimen. The rule is: Never place the bones of the -first joint (Plate IX. No. 1) and those of the second joint (2) of the hind legs in a straight line, but always at an dangle, more or less ; while the two bones of the forelegs (3, 4) should almost always be placed in a straight line, — always when the animal is standing upon them. In imitating that peculiarly graceful attitude assumed by the squirrels while sitting upon their hind legs feeding, after imitating the curve of the back, — which not one in a hundred can do naturally, — place the joints of the hind 52 THE NATURALIST’S GUIDE. legs so far up, and at such an acute angle, and the joints of the forelegs down at such an angle, that the two will almost touch. This rule should always be followed. The preceding method may be applied when mounting all animals below the size of a Newfoundland dog. Larger animals are mounted in the following manner: Fill out the space occupied by the muscles of the head and legs in the manner already described. Procure five iron rods, with a shoulder cut at each end, upon which fit a cap (Plate IX. Fig. 2, B); on the extreme end have a thread cut with a nut to fit (A), — the distance between the nut and cap should be about an inch and a half. Cut a piece of plank, an inch and a half thick, about two thirds as _ . long and wide as the body of the mammal to be mounted ; bore five holes in it, as indicated in Fig. 1, A. Fasten one rod (8) firmly to the skull by drilling a hole through the top and placing the cap in the proper position. Screw the nut on well (14), and place the lower end of the rod in the hole in the plank prepared for it (11) ; fasten it firmly. Now stuff the neck out with hemp to the proper size. Drill a hole through the hoofs, or bottom of the feet, into the hollow of the bones (2, 4); force the rod (7, 7, 7, 7) up through this hole, through the stuffing of the legs, and fasten them into the plank (5, 6). Force a wire into the tail and clinch it firmly in the wood (15). By winding up grass or hemp, imitate the various sections of the body taken out, and place them in the proper positions (16), making allowance for the plank and rods. Or a better way is to take casts in plaster of the different parts and place them in the proper position. Everything must be solid, to avoid sinkings and depres- sions in the skin. In this way the student can mount an animal of any size by increasing the size of the rods and plank. The ends of the rods must be fastened into a plank ‘stand (10) by passing them through holes drilled in it (17, 17, 17, 17). THE WAY TO MOUNT MAMMALS. Plate IX. 53 54 _ THE NATURALIST’S GUIDE. To mount a dried skin, first soak it in alum-water until it is perfectly pliable, and then mount as before. The water should not be too strongly impregnated with alum, or it will crystallize upon the hair. About a quarter of a \pound of alum to a gallon of water are the proper propor- tions. Ifthe skull has been detached, replace it, or make an artificial one of grass or plaster to take its place. Mam- mals that have been preserved in alcohol may be skinned in the usual manner and mounted. To skin mammals for the fur alone, cut in a straight line from the inside of the knee of one hind leg to the other. Skin as before explained, only cut off the feet and detach the skull. Stretch smoothly on a thin board, with the . wrong side out. The skin should be lengthened rather than widened. ———— CUMAP TER: TF. COLLECTING AND PRESERVING INSECTS FOR THE CABINET. Tus interesting class of animals has for a long time engaged the attention of students, yet it is surprising how comparatively little has been written about those of Amer- ica. The almost infinite number of species still affords the young naturalist a wide field for careful investigation. In collecting insects, the instruments used are: An msect- net, made of fine muslin or of silk gauze, and stretched upon a light steel wire frame, with a light handle, about four feet long, attached ; several wide-mouthed bottles and phials filled with strong alcohol; insect-pins of the best quality, which can be procured at natural-history stores ; tweezers smaller than those used for birds (Plate I. Fig. 3); also, a small pair of pliers (Fig. 1) ; several soft-pine boards about twelve by twenty-four inches, planed perfectly smooth, will also be needed. Boxes or drawers are necessary for the reception of the dried specimens, lined with thick felting or cork to receive the point of the pin that holds the insect and keeps it upright. An excellent box lined with paper is sometimes used to advantage, a description of which may be found in the “American Naturalist,” Vol. I. p. 156. I hardly need state that a good microscope is indispensa- ble in prosecuting the study of insects, although it may be commenced without one. I shall take each order of insects “separately, and endeavor to explain how they are collected and preserved, commencing with the Beetles, or Coleoptera.—The best way to preserve bee- tles temporarily is by putting them instantly into strong 56 THE NATURALISI’S GUIDE. alcohol; and as the collector will meet with specimens everywhere, he should never be without a phial ready for instant use. During spring and early summer thousands of minute species may be captured in the air with the net, especially just at night. During summer and autumn a great many nocturnal species may be captured near a light placed at an open window, or in the open air. Vari- ous species may be found feeding upon plants during the summer and autumn. A great many of the so-called car- rion-beetles may be taken, during the same seasons, by ex- posing the carcass of an animal. Some species inhabit decayed wood, where diligent search should be made for them, especially in the woods, under old stumps or in them. Numbers of very beautiful beetles may be found in the excrements of animals, and under them, also under stones and logs of wood ; they are found beneath the bark of trees and on sandy places, or in dusty roads. There are also a few aquatic species to be found in the water or near it. To mount large beetles, force the pin through the right wing-covert near the thorax, and place the point in the cork, with the beetle’s feet resting on it; place the feet in the attitude of life, with the antenne in the proper position, with a pin on each side of them to keep them in place until dry. If the wings are to be extended, place the beetle on the pin as described; then, with an awl, bore a hole in the pine board ; lay the insect upon — its back, with the head of the pin in the hole ; now open the wing-coverts, and spread the wings; over the latter lay a piece of card-board, and fasten it by placing pins through it into the wood on each side. The wing-cov- erts should not be fastened with a card, as it will flatten them. When dry, remove the card, and the wings will retain their position, when the beetle can be put in the proper position in the insect-box. Smaller beetles, less than an eighth of an inch long, BUGS, OR HEMIPTERA. 57 should be fastened to a piece of mica or to a round bit of card-board with a little gum-arabic, and the pin placed through the mica or card, or they may be transfixed with very fine silver wire; this wire must then be inserted in a bit of cork, through which the common insect-pin is placed. Beetles that are collected in remote countries should always be transported in alcohol. When they are to re- main long in alcohol it should be changed once, then they will keep for years uninjured. After they have been in alcohol for two or three weeks there is no need of its covering them, as a little in the bottom of the bottle will keep them sufficiently moist; but they should never be allowed to dry. Beetles may be preserved in a weak solution of carbolic acid as readily as in alcohol. This has the additional ad- vantage of preserving the specimens that have been im- mersed in it from the ravages of noxious insects for some time. Glycerine can be used to advantage in preserving beetles that have delicate colors which fade in alcohol ; but they cannot be pinned without cleansing. Bugs, or Hemiptera, may be found generally upon plants. The common thistle (Cirs’um lanceolatum) furnishes a pas- ture for several species. Numerous representatives of this order may be found on low bushes, and in the grass during summer and autumn. At least one species may be found in cheap boarding-houses during the midnight hours. The almost endless variety of Plant Lice come under this head, and may be taken everywhere on plants during summer and autumn. These insects, like the beetle, are first immersed in alcohol, and afterwards placed upon pins, with the legs arranged in natural positions, and the peculiar sucking- tube, with which they are all provided, brought well for- ward so as to be more easily examined. The numerous 3% 58 THE NATURALIST’S GUIDE. aquatic species may be secured with a net ; they should be carefully handled, however, to avoid the sharp sting, or piercer, with which some of them are armed. Grasshoppers, Crickets, ete., or Orthoptera. — Members of this order may be found everywhere, — the grasshoppers in the open fields and woods, where they may be caught in nets. The best way to kill them is to prick them on the under side of the thorax with the point of a quill that has been dipped in a solution of oxalic acid. If they are not to be mounted instantly, wrap them in paper. Crickets may be found in the ground in holes or burrows, under stones, and in the grass; a few species may be taken on the leaves of trees or bushes ; some species of the well- known Cockroach may be found in houses, and some under stones and beneath the bark of trees. All of the above may be mounted by placing the pin through the thorax, and arranging the legs as before de- scribed. The wings are also extended in the same man- ner as the beetles’, with the exception of the wing-coverts, which are fastened with cards like the wings. Walking-Sticks are found on low bushes or on trees, some- times upon the ground. They are to be put into alcohol to kill them, then mounted like the beetles. These in- sects, when dry, require delicate manipulation while being moved, as they are very fragile. When the colors of the Orthoptera are to be preserved perfectly, place them in pure glycerine. This is especially necessary in preserving the larvee of grasshoppers. Grasshoppers may be put into alcohol if convenient, but it must be very strong. This method will generally change the colors completely. Cock- roaches and crickets should always be killed by placing them in strong alcohol. Moths and Butterflies, or Lepidoptera. — All butterflies are diurnal, and are generally caught with the net. They may be killed by pinching the body just below the wings, MOTHS AND BUTTERFLIES, OR LEPIDOPTERA. 59 or by pricking between the forelegs with the quill and oxalic acid used in killing grasshoppers. If they are not to be mounted instantly, they should be packed in pieces of paper doubled in a triangular shape, with the edges folded. Butterflies may be reared from the egg by capturing the impregnated female and confining her in a box pierced with holes to allow fresh air to enter. In this box she will deposit her eggs; these are allowed to hatch, and the larvee fed upon the leaves that they natu- rally subsist upon. When sufficient time has expired they will cease to feed, and form a pupa or chrysalis, and either in a few weeks or the ensuing year come forth perfect insects, when they should be instantly killed. In this man- ner the collector will be able to secure fine specimens. Although some few of the moths are diurnal in their habits, the greater part are strictly nocturnal.
