Domesticated animals

by Nathaniel Southgate Shaler

There is another inhabitant of the high north of this continent which deserves the notice of those who are disposed to attend to the questions concerning the extension of man's control over nature; this is the ovibos or musk-ox. Like the buffalo, only in much higher measure, this singular creature is fit for very cold countries; his fitness being in part assured by his admirable covering of long hair as well as by his capacity for taking on fat during the short summer in sufficient store to last him through the trials of the winter season. The kinship of the musk-ox to the group of the sheep is near enough to warrant the belief that the hair could be improved by selection, and that from the process we would be likely to obtain an animal much larger than our largest sheep and yielding fleeces of peculiar value in the arts.

Among the northern carnivora there are several species which deserve attention for the reason that they may be brought to some degree of domestication which may enable us to make better use of their hairy coverings. Among these we may mention the foxes, the polar bears, and the seals. The first-named group affords at present about the dearest furs of our markets. The silver-gray variety, which at present seems to be a frequent individual variation, could doubtless be affirmed by selection, and probably could be brought to a higher state of perfection than it has as yet attained. The animals are, if we may judge from their kindred, not untamable; at least they could be brought to live in a sufficient state of captivity to permit selection. In time they might be quite domesticated. Many of the islands of the high north and south are well fitted for such experiments.

As is well known, the polar bears have a wonderfully developed hairy covering; their coats, indeed, are among the richest that exist. These animals subsist mainly on what they capture from the sea, so that it might be possible to keep them at a small expense. They are, however, of all their kindred the most indomitable; it would probably require a long and costly effort to reduce them to anything like domestication. Moreover, being strong, free swimmers, it would not be easy to maintain them in captivity. Still, selecting such a well-inundated place as Bear Island of the North Atlantic, it would be most interesting to make the experiment, first of accustoming them to some human control, and then to a selection which might serve to lift the quality of the kind. It would be less difficult and perhaps more advisable at first to make a trial of a similar sort with the black bear, which in less arctic conditions flourishes and carries a fine pelt. The only difficulty would be in finding a sufficient supply of food for such captives, for although they will eat fish they have no skill in capturing them such as is possessed by their more degraded, or perhaps we should say their less advanced kindred, the polar bears. Still, as the form is even more omnivorous than man, it might be practicable to feed them.

By far the most important of the carnivora in an economic sense are the seals which dwell in the high northern waters. These creatures afford the most interesting subjects for experiments in domestication from an economic point of view that remain to be made. Of all the predatory animals the seals seem to have the largest share of intelligence and the greatest amount of sympathetic motives. No other wild animals, except perhaps the monkeys, appear to be so human-like in their qualities of mind as these creatures of the sea. So far, except when they have been captured and kept for purposes of show in menageries, man's relations to the seals have been purely destructive; he has incessantly hunted them. Yet certain species of them remain singularly willing, we may say desirous, of claiming friendship with their persecutors. As elsewhere noted, wounded seals behave in a curiously appealing way towards their assailants. When in captivity certain of the species show a remarkable friendliness and a capacity to receive training. No other wild animals, except perhaps the elephants, exhibit so great a fitness for profiting from contact with man.

Although our knowledge as to the habits of seals is still very imperfect, it appears likely that the greater part of the species have the habit of resorting to certain places during the breeding season, and that the individuals after the manner of certain fishes return at that time to their native shore. If this be true, as there is good reason to believe it is, it should not be a matter of grave difficulty, provided the maritime nations would abet the experiment, to establish seal colonies composed of the several promising forms at fit points in the circumpolar seas. There is reason to suppose that with ordinary decent treatment the animals would become to a great degree accustomed to men, and that it might be possible to accomplish selection enough of the individuals which were left to breed, to develop the already valuable characteristics of the fur. In the present disgraceful condition of our relations to these animals it will be but a few years before we shall have to lament the extirpation of several species, including the most interesting members of the group.

Looking upon the questions of man's future on the earth in a large way, we see that there are reasons why the animals of the high north, particularly those which obtain their food from the sea, should be protected from extermination. There is a great area of country in that part of the world which is not adapted to the occupation of any of the species which have as yet been domesticated. If this portion of the world is ever to prove fruitful in other ways than through its mineral stores, it will be by the creatures which are adapted to its climate and other conditions. At the present rate of increase in numbers, the population of the world will, in the course of two or three centuries, begin seriously to press upon the resources in the way of food which the fields of the tropical and temperate zones can supply; the chances of the arctic regions may then have much importance to our successors. Moreover, in the case of the seals we find the peculiar advantage that the animals are fed entirely from the sea, so that the domestication of these forms would give to man a means, the like of which he has never possessed, whereby he would be enabled to harvest the food resources of the deep.

The beaver, particularly the North American form, offers a most attractive opportunity for a great and far-reaching experiment in domestication. On this continent, at least, the creature exhibits a range of attractive qualities which is exceeded by none other in the whole range of the lower mammalian life. No other mammal below man shows anything like the same constructive skill in the contrivance of its habitations, or is able so to modify its habits of building to meet the varied needs of its life. When this country was first visited by man near one half of its area was occupied by this species. It built its dams and dwelling-places and, when necessary, excavated its canals along all the lesser streams in the timbered regions of the northern districts. As the destructive effects of civilization increased, the animal has gradually, to a great extent, been driven away from its old haunts, and where it remains it has, as the price of life, given up its architectural habits and betaken itself to the older and simpler mode of living in a chance manner much as is now the habit of the European variety. As an illustration of this I may note, in passing, that before the civil war, when all the recesses of the forests in the region about Richmond, Virginia, had for more than a century been industriously explored by hunters, the beaver was supposed to be extinct in the district; yet during the civil war, as I am credibly informed, a colony of these creatures became established near the town of Suffolk, and there, amid the roar of a great conflict in which men ceased to seek the lesser game, they recovered their habit of building dams, which we must believe to have been discontinued for many generations. This capacity to vary action with reference to changing needs is the best possible index of the mental power of animals. Guided by the exhibition that has been given us by the beavers, we are justified in considering them to be the one group of mammals which has gained a distinct, rational constructive power. This feature makes them decidedly the most interesting group for investigations which may be expected to throw light on the problems of animal intelligence. From the economic point of view the species has a certain importance for the reason that it affords one of the most valuable kinds of fur that has ever been marketed.

The domestication of the beavers to the point where they would tolerate the presence of man should not, provided they could be protected against the depredations of poachers, be a matter of any difficulty. The colonies of these animals require only what is afforded by vast realms of our wildernesses—flowing streams of moderate fall with timber upon their banks. They are not particular as to the species, so that swift-growing kinds of trees such as the poplars may be made to serve their needs. The natural growth on a hundred acres of otherwise worthless land would probably be sufficient to maintain a colony of average size containing say twenty-five individuals. In the region about the great lakes and for some distance to the northward and to the east and west there are great areas amounting in the aggregate to some hundred thousand square miles that would apparently be well suited to the nurture of this form, and which in the present condition of the country, as well as for the immediate future, cannot be turned to better use. It may be remarked that the domestication of the beavers would afford yet another means, in addition to those above noted, whereby we might be able to win some profit from the great wilderness of the north, which is, so far as our existing means of appropriating its resources, of little use to mankind. The only evident way by which we may hope to win profit from this part of our continent is by using it as a field for rearing animals that have yet to be subjugated; none of our captive varieties are fit for the service.

In the tropical parts of the world there are many mammalian species which are worthy subjects for essays in domestication. This is particularly the case in the continent of Africa where, except in the lands about the Mediterranean and the Red Sea, the native peoples have never attained the stage of culture in which men become strongly inclined to subjugate wild animals. Africa is richer in large herbivorous species than any other of the great lands; many of these forms are of large size and have qualities of flesh, of hide, or other peculiar features which promise to make them valuable in an economic way. Others, especially the antelopes, have a beauty of form and a grace of movement which render them among the most attractive creatures of their class. Even the hippopotamus, one of the grossest beasts of this realm, affords in its teeth a valuable ivory, and its hides, if supplied in sufficient quantity, would probably find a considerable use. It is evident that in this "dark continent," where the influences which make for human advancement have been so slight, we have the best field for the selection of species that may hereafter be brought to the use of man. There is evidently danger, in the advance in the civilizing process, that the native forms which, owing to their fitness to the physical conditions of the country, might be made useful to its people, may be utterly destroyed by hunters.

Perhaps the most interesting of the tropical beasts from the point of view which we occupy is the elephant: This animal in its relations to men is eminently peculiar, in that while it has been in an individual way long and completely subjugated, it has never been systematically reared in captivity. Owing, it may be, to the slow growth of these great beasts, as well as to the immediate manner in which they submit to their captors, it has ever been the custom to take them when adult from the wilderness. The result is that the supply of the Asiatic species, which alone is serviceable—the African form being apparently too fierce for use—is now dependent on a relatively small number of wild herds. Certain of these herds are protected by the governments of India, but it seems as if the species were already dangerously near the vanishing point—in a position where the invasion of some disease or some insect enemy might deprive the world of what is, all things considered, the most interesting of the brutes. Moreover, the failure to rear elephants in captivity has made it impossible to essay any of those experiments in breeding which have done so much to improve the utility and the beauty of most subjugated forms.
