A group of American opossums may be taken as a good example. The case which encloses the entire group is 4 feet long, 3 feet wide, and 3 feet high. The frame of the case is as light as possible, and all four sides and the top are of gla.s.s. On the side of a sloping bank stands the base of a small gum-tree, with the roots on the lower side exposed by the crumbling away of the bank. Of course the trunk rises to the top of the case, where it is cut squarely off. At the bottom of the sloping bank, between two of the roots, is an opening, which is recognized at once as the doorway to the opossum's home. The burrow winds upward between the roots of the tree, and finally turns off to the left into the bank, where, after running through a pa.s.sage-way of two or three feet in length, the nest itself is found. It is in a pocket-like excavation, and a circular section is cut out of the front of the bank so as to make an opening through which the nest can be seen.
The nest is lined with dead leaves, in which lies an opossum curled up and sound asleep. At the back of the case a sectional view of the bank is represented, and by means of an opening cut here and there, the course of the burrow is plainly seen. In the foreground is an old mother opossum with several young ones riding on her back, clinging to her gray coat, while the head of another protrudes from her pouch. This represents the manner in which the opossum carries her young after they have reached a certain age.
From a small branch hangs another opossum, suspended by its prehensile tail, sprawling in mid-air. This specimen is a female, and shows the size and location of the wonderful marsupial pouch. Another individual is climbing up the trunk of the tree. A fourth specimen, which has been disturbed by another, is pausing to protest with widely opened mouth, while in the act of creeping into the mouth of the burrow.
Please notice the number of facts that are taught by this simple little group. It shows that the opossum is a marsupial, and the female carries her young in a pouch in her own body; that when the young reach a certain age, they ride upon the mother's back, clinging to her fur; that the animal is arboreal in habit, and has a prehensile tail, by which it is capable of suspending itself; that it burrows in banks in dry situations, and sleeps curled up like a ball in a bed of dry leaves. It also shows the full size of the adult, the young of the previous year, and the recent brood. But for an unfortunate accident, which has yet to be repaired, it would also show the number born at one birth. Of course in this group the gra.s.s and moss is properly represented, and there are artificial leaves on the tree branches which enter the group.
Groups of this cla.s.s can easily be made to show the ordinary nesting and breeding habits of the animals represented. Now it happens that animals of some species make a variety of nests, according to circ.u.mstances or caprice. In 1889 we prepared a group in three sections, each of which shows one of the habits of the gray squirrel in nesting. Each is composed of an actual nest, and in the identical tree in which it was built by Bunny himself. One represents a nest in a hollow beech tree, in which a pair of gray squirrels bred for years. Another is what might be called a summer nest, made of cedar bark, in the top of a cedar tree. It is a round ball, and in size and shape much resembles a hornet's nest. The third section represents an outside nest of green oak-leaves, placed on a branch of an oak tree. These three groups are exhibited in one case, but while each is separated from the others by a plate of heavy tinted gla.s.s, it is made apparent that they all ill.u.s.trate the habits of the same animal. The specimens composing the three groups were all collected within a radius of ten miles of the city of Was.h.i.+ngton. Besides teaching what the nesting habits of the gray squirrel are, it also impresses upon the observer the very important fact that the habits of different individuals of a given species are capable of wide variation. They show how dangerous it is for a student or scientific investigator to generalize too freely from one or two facts, and that it is dangerous for anyone to say what an animal will _not_ do!
In beginning the preparation of small mammal groups (for a museum) the following hints may be of service: It is not necessary that a small group should be designed and sketched out in advance. The first step, therefore, is the finding of a typical family of specimens, and a suitable burrow or nest. The character of the creature's home will largely determine the design of your group. By all means endeavor to secure a nest or burrow which can be fitly shown as a typical home of the creature represented.
When the nest of an animal is situated in a tree, it is nearly always possible to cut out a section of the tree, and introduce it bodily into your case, with appropriate leaf settings. When an animal burrows in the ground, as do the fox and the woodchuck, the best that can be done is to dig out the spot carefully, taking measurements and diagrams as you proceed, to show the direction and size of the entrance and the exact shape and size of the nest. You can then manufacture a bank and reproduce a perfect fac-simile. Of course all the nest materials--refuse bones, hair, and feathers--must be taken along bodily, and used in the manufactured nest.
In displaying a portion of a tree-trunk which contains a nest, it has been our custom to saw out a rectangular section at one side of the hollow, and hang the piece on hinges at one side of the opening, like an open door, so that the entire interior and the situation of the nest can be seen. Of course it is in order to place a number of the young specimens in the nest in characteristic att.i.tudes.
When you have collected a number of young specimens, mount them at once while the forms and att.i.tudes are fresh in your mind and the skins are in good condition. If you are lucky enough to get the young alive, you can mount some of the skins while the others serve as living models.
Now comes an important point. It usually happens that at the time when the young are of the best age to display in a group, the fur of the adult specimen is at its poorest. Worse than that, shedding is often in progress.
No matter what hypercritics may say, do not hesitate to perpetrate an anachronism by taking _adult_ specimens later in the season, when their fur is at its best. It would be an injustice to the group, to the species, and to yourself, to include adult specimens in their poorest pelage. Along with your groups of young animals, which necessarily represent conditions during spring or summer, do not forget to represent some of your species in their winter homes, with their stores of nuts, acorns, etc., for winter use.
The field open to the conscientious and really artistic taxidermist in the preparation of groups is a wide and deeply interesting one. I know of no branch of taxidermy which ought to be more interesting than this. Its possibilities are open to all. While it is impossible for everyone to prepare groups of large mammals, in the matter of small groups you can say, "The world's mine oyster."
GROUPS OF LARGE MAMMALS.--In creating a high-cla.s.s group of large mammals, it is, as has been stated before, extremely desirable to prepare the design first, and collect the specimens to suit it. There is no burrow or nest to reproduce, and this course is not only possible, but usually very necessary.
There is one important fact which should never be lost sight of in the preparation of a design for a group of large quadrupeds. If the animals are purely terrestrial, as will be the case in nearly all large groups, the largest and finest adult male and female should each stand on a flat and horizontal surface, in easy and conventional att.i.tudes. This is necessary in order that the form, height, and back outline of each of the typical adult specimens can be studied by the technical zoologist with as much certainty and accuracy as any ordinary case specimen standing on a flat pedestal of hard wood. To ill.u.s.trate the point: If the huge bull bison in our large group had been put walking up hill, or walking down hill, it would now be practically impossible for anyone wis.h.i.+ng to draw a picture of him to accurately determine the precise angle of his hump. Furthermore, his height at the shoulders would be either exaggerated or diminished, almost unavoidably. As it is, he was with deliberate intention mounted on a flat and horizontal surface, as was the cow also, so that even though they are in a group they lose nothing whatever of their value to the technical zoologist, who demands that all specimens shall be mounted on flat surfaces, and in conventional att.i.tudes for the sake of comparison. Having done this much for pure science, we are at liberty to vary the att.i.tudes of the remaining specimens of the group.
In a museum group suppress all tendency to the development of violent action on the part of your specimens. In a well-regulated museum no fighting is allowed. Represent every-day, peaceful, home scenes in the lives of your animals. Seek not to startle and appal the beholder, but rather to interest and instruct him. Surely there are enough quiet and peaceful att.i.tudes to supply all your specimens without exhausting the stock. Let them be feeding, walking, climbing up, lying down, standing on the alert, playing with each other, or sleepily ruminating--in fact, anything but fighting, leaping, and running. If you do not happen to know the habits of the animals which form the subject of your group, and it is impossible for you to learn them by observation, then must you throw aside all reserve, and appeal to some one who has seen and studied them in their haunts.
It is no child's play to prepare a group of large mammals. It invariably costs several hundreds of dollars, perhaps even thousands, and the work is supposed to last a century or longer. Judge, therefore, how important it is that every detail of the work should be absolutely above criticism. If you mount such a group in haste, you are certain to repent at leisure.
Having prepared your design, collected your specimens, and made all your studies for the entire group, the next step, of course, is mounting each individual specimen. It is an excellent plan, and one which we have found particularly satisfactory in grouping ruminants, to prepare all the manikins before putting any skin on permanently. We begin with the most important specimen. By mounting the manikins one by one, and grouping them, we are able to secure the precise artistic effect that was intended in our design. The grouping of the naked manikins from time to time enables you to eliminate errors, and make such changes in the att.i.tudes as the eye may suggest.
A few facts in relation to the work done in setting up the buffalo group will serve as a fair index to work of this kind. Of course it is to be understood that every case is to have a wooden floor, and that one end can be opened bodily. Each of our buffaloes stood on a strong, thick base by itself, a rough pedestal, in fact, of a very substantial character. With pine boards we built a miniature hill, on which stands the spike bull, placed him upon it, and fastened him there permanently. The final work of arrangement was not undertaken until a trial grouping in the case had been satisfactorily made, and the exact position of each specimen definitely settled. A hole was cut in the bottom of the case, to give depth to the pool of water. The bottom of this pool was carefully modeled in papier-mache, and painted. The specimens standing farthest from the end containing the doors were first put in place, and the groundwork built up around them. The face of the cut bank was made by nailing wire cloth to a skeleton framework of boards, and covering this with a coa.r.s.e sort of papier-mache, made of sawdust, plaster Paris, glue, and hair, and used in large quant.i.ties. As fast as a specimen was put in place and fastened, the rough groundwork of boards was covered with the papier-mache composition to make a perfectly smooth foundation to receive the prairie sod. From first to last, between three and four barrels of this coa.r.s.e papier-mache was used. It was made to set quickly, and the modeling which was done on the surface of the cut bank, and in the bed of the stream, was done as soon as the soft material was put on. The surface of the pool was represented by a sheet of plate gla.s.s, a quarter of an inch thick. The entire groundwork of the case was covered with genuine prairie sod, each piece about one inch thick and a foot square, cut on the buffalo range in Montana, and s.h.i.+pped in barrels to Was.h.i.+ngton.
When this sod became perfectly dry, it lost all color and had the appearance of cured hay. In order to give it the right tone, it was necessary to spray it with a thin mixture of green paint in turpentine, to impart to it a pale green tint. As soon as the papier-mache was dry, the sod was cut neatly, matched carefully, and laid upon it--the joints being skilfully closed. A number of clumps of sage brush and bunches of broom sedge, grubbed up in Montana and carefully dried, were set here and there through the group. A bed of cactus was also introduced in the foreground.
The sage brush required no preparation except to pack it carefully, and dry it after it reached Was.h.i.+ngton, with the branches in position. The leaves were of the right color when dry, and remained attached to the stems. Montana dirt was used in the bottom of the buffalo trail, and on the side of the cut bank. A few buffalo bones were stuck in the side of the bank to represent fossil bones as they are often seen protruding from the faces of cut banks in Montana. While the papier-mache around the edge of the pool was yet soft, tracks were made in it with genuine buffalo hoofs of various sizes, and many more tracks were made in the dust in the bottom of the buffalo trail. Of all the accessories in the buffalo case, everything in sight came from the Montana buffalo range, except the sheet of gla.s.s forming the surface of the pool.
The last six months of my connection with the National Museum witnessed the completion of the great group of moose, which we began in 1889. In size and general make-up it is a companion piece to the group of buffaloes, and is a memorial worthy of the colossal species it represents. The setting represents a section of the moose woods of Upper Canada, in which the larger animals are browsing on the tender twigs of the white birch. The animals have come together at the edge of a bog, which is growing full of a gigantic species of grayish moss, peculiar to that locality. The time represented is the middle of autumn. The few leaves that remain on the maple saplings have been painted with October's most gorgeous tints of crimson and yellow, mixed with green, and the leaves of the white birch have turned pale yellow. The ground is plentifully strewn with leaves of bright tints, through which the green moss of moist banks shows in patches here and there.

Of the animals, the three largest--and huge beasts they are, truly--are feeding upon the birch twigs. A yearling calf is licking the head of a tiny brown-coated younger brother, while a two-year-old bull is in the act of "riding down" a stout birch sapling in order to get at the branches of its top, which would otherwise be beyond his reach.
Three of these fine specimens were collected by Colonel Cecil Clay, of Was.h.i.+ngton, and by him presented to the Museum for this group, together with the trees, moss, and other accessories, which he collected with infinite labor and care in the moose woods. He also furnished us with field notes and critical advice throughout, which had much to do in making the group what it is--a monument to Colonel Clay's skill and prowess as a sportsman, and to his deep interest in _Alces malchis_. It is to be sincerely hoped that other sportsmen will follow the Colonel's admirable example, and aid the museums in which they are most interested to secure some attractive groups.
The moose group was followed immediately by the group of musk-oxen, and there are others of Rocky Mountain goat, mountain sheep, and sea-lions in course of preparation.
CHAPTER x.x.xII.
GROUPS OF BIRDS AND REPTILES.
The principles which underlie the production of successful groups of birds are precisely the same as those which have already been set forth under the head of "Groups of Small Mammals." In addition, however, there is another which should be kept constantly in mind, viz., to guard against the temptation to permit the accessories of a group to completely overshadow, and, I might say, overwhelm, the specimens themselves. Be careful to make the birds conspicuous, and to avoid the appearance of an exhibit of artificial plants and flowers, instead of mounted birds.
Of course each species must be represented by itself in a case which shall contain its nest, displayed in the identical bough, or bunch of gra.s.s, or hole in the bank which it occupied when found by the collector. Except when a nest is situated in a bank of earth, the collector should cut a square section out of nature, of the proper dimensions for casing, and convey bodily the nest and its situation to the museum. Occasionally circ.u.mstances will prevent this, when it becomes necessary to collect the nest and the material surrounding it, so that with their aid the situation of the nest can be built up in the laboratory.
The finest groups of birds to be found in this country are those in the American Museum of Natural History in New York, which are the work of Mr.
Jenness Richardson. At present (1891) the series consists of groups composed almost wholly of species found in the State of New York. Each group, except in a few instances, occupies a light, iron-framed case by itself, and stands on an ebonized table-base, raised on legs about eighteen inches from the floor. The framework of the case, and the wood-work of the base is painted black. When the home of a ground-nesting bird is shown, a section has been cut from mother earth, placed on the base as the foundation, and all the perishable plants growing thereon have been carefully reproduced in wax by casting, and put back in place.
Where a nest was situated in a low bush, the bush and its foliage, and the ground beneath have all been included in its transfer. When a nest was placed on the end of a bough, the difficulty has been surmounted very satisfactorily by cutting off as much of the bough as could be put in the case, then reproducing, on the bottom of the case, the ground exactly as it was under the tree, and simply laying carelessly upon it the cut branch containing the nest and the birds. Of course watery situations call for the introduction of the plate-gla.s.s imitation.
The feature of these groups that is so pleasing is that each one appears to have been cut out of its place in field or forest, and brought to the museum within an hour. The life-like birds, the earth and water, the natural wood, and the beautiful foliage of spring combine to impart to each group the breezy freshness of the forest, the very soul of Nature all unchanged.
To see these charming productions, fresh from the hand of a true artist-naturalist, and lay aside the spirit of carping criticism which would find fault with even a heavenly harp, is the next thing to finding one's self in the actual haunts of our native birds, with their songs trilling in our ears. Mr. Richardson's groups lack but one thing--the song of the birds. They are so many pretty pages from Nature's choicest book, and actually bring the life of the forest into the otherwise dead and silent museum hall.
The time will yet come when our wealthy lovers of art and animated nature will find places in their houses for such groups as these, and the money to pay for them will be forthcoming. At present they are tired of the old-fas.h.i.+oned gla.s.s "shade," covering a stiff and utterly unnatural pyramid of small stuffed birds on an impossible "tree." The old-fas.h.i.+oned wall-case of birds also fails to satisfy the aesthete, for the simple reason that something better is wanted. We are all ready to step up to a higher plane.
GROUPS OF REPTILES.--I know of but one good group of reptiles, and that is a group of turtles which was prepared by Mr. F.A. Lucas, and displayed at the exhibition of the S.A.T., in New York, in 1883, where it received a medal, and afterward was presented by him to the National Museum. This altogether unique and pretty group teaches one very important lesson, viz., that even the most commonplace animals are interesting when they are well mounted, and grouped with a setting which represents their natural haunts.
Some of the specimens in this group are represented above water, and some beneath it, while one enterprising individual is caught in the act of diving, with part of his body under water and the other half out. The situation represents the successful accomplishment of a very neat mechanical feat, and is of itself an ill.u.s.tration of the possibilities in such matters.
After the quadrupeds of North America have been gathered and grouped until there remain in that direction no more worlds to conquer, it will be quite in order for our enterprising taxidermists then to proceed to the mounting of groups of reptiles.
There are possibilities with such subjects as the crocodiles, iguanas, lizards of various kinds, serpents, and turtles that few dream of. Already Professor Goode has under consideration the production of a series of reptilian groups for the National Museum, and within a short time the work will be undertaken.

HINTS ON PAINTING MUSEUM SPECIMENS.
In the preparation of museum specimens in general there is, from first to last, a great deal of painting to be done, and a knowledge of how to paint specimens properly is quite as necessary as a knowledge of how to mount them.
