Third, he should have something of the artistic sense to make his groups pleasing as well as accurate.
Fourth, he must know the technique of manikin making, the tanning of skins, and the making of accessories such as artificial leaves, branches, etc.
With all these different kinds of technique in taxidermy it is obvious that if a man attempts to do practically everything himself, as I did in the deer groups, taxidermy must be a very slow process—just as if a painter had to learn to make his own paint or a sculptor to cast his own bronzes or chisel his concepts out of granite or marble.
The proper care of the skins in the field is itself a subject of infinite ramifications. I remember, for instance, my experience in skinning the first elephant that I killed. I shot him in the early afternoon. I immediately set to work photographing and measuring him. That took about an hour, and then I set to the serious work of getting off his skin. I worked as rapidly as I could, wherever possible using the help of the fifty boys of my safari, and by strenuous efforts finished taking the skin off and salting it by breakfast time the next morning. And that was not quick enough. Before I got all the skin off the carcass some of it on the under side had begun to decompose and I lost a little of it. This was a particularly difficult beast to skin because he had fallen in a little hollow and after skinning the exposed side of him all the efforts of the fifty black boys to roll him over, out of the depression, so that we could easily get at the other side, failed. After I had had more practice, I was able to photograph, measure, and skin an elephant and have his hide salted in eight hours. But then the work on the skin was only begun. A green skin like this weighs a ton and a quarter and in places is as much as two and a half inches thick. There is about four days' work in thinning it. I have had thirty or forty black boys for days cutting at the inside of the skin in this thinning process or sharpening the knives with which they did the work.
When it is finally thinned down, thoroughly dried and salted, it presents another problem. Moisture will ruin it. Salt, the only available preservative, attracts moisture. It isn't possible to carry zinc-lined cases into the forests after elephants. I tried building thatched roofs over the skins but it was not a success. I speculated on many other plans but none appeared feasible. Finally Nature provided a solution for the difficulty.
There are, in the elephant country, many great swarms of bees. I set the natives to work collecting beeswax which is as impervious to moisture as shellac. I melted the wax and used it to coat unbleached cotton cloth, known in East Africa as Americana. In this water-tight, wax-covered cloth I wrapped my dried and salted rolls of skins and packed them on the porters' heads down to the railroad.
As a matter of fact, field conditions make it so difficult to care for skins properly that only a very small percentage ever reach a taxidermy shop in perfect condition.
Similarly the measurement of animals for taxidermy presents many difficulties. The size of a lion's leg, for instance, measured as it hangs limp after the animal's death is not accurate data for the leg with the muscles taut ready for action. Nor is an animal's body the same size with its lungs deflated in death as when the breath of life was in its body. All these things must be taken into account in using measurements or even casts to resurrect an animal true to its living appearance.
My work on the deer groups impressed me with the fact that taxidermy, if it was to be an art, must have skilled assistance as the other arts have. I began to dream of museums which would have artist-naturalists who would have the vision to plan groups and the skill to model them and who would be furnished with skilled assistance in the making of the manikins and accessories and in the mounting of the animals. And it seemed as if the dream were about to come true. About this time I had a conference with Dr. Herman Bumpus, then director of the American Museum of Natural History in New York. He told me that he had then at the museum a young man named James Clark who could model but who did not know the technique of making manikins and mounting animals. The result of our talk was that Clark came out to my shop in Chicago and together we went through the whole process, mounting a doe which now stands in the American Museum. But the old museum trouble broke out again. It cost a lot to mount animals in the method which Clark brought back. So there was pressure to reduce the cost and, under this pressure, the methods, in the words of O. Henry, "were damaged by improvements." However, in the course of time it was demonstrated that while it often happens that an honest effort to make a thing better often makes it cheaper also, an effort merely to cheapen a thing very seldom makes it better.
In the meanwhile, in 1905, I went to Africa again, to collect zoölogical material for the Field Museum.
