Part 14

Not only is the motive which has led our race to such extensive conquests over the wild nature in itself sympathetic, but the process of winning these creatures from the wilderness has served effectively to extend and amplify this same impulse. One of the best features of agricultural life consists in the great amount of care-taking which it imposes upon its followers. The ordinary farmer has to enter into more or less sympathetic relations with half a score of animal species and many kinds of plants. His life, indeed, is devoted to ceaseless friendly relations with these creatures which live or die at his will. In this task his ancient savage impulses are slowly worn away, and in their place comes the enduring kindliness of cultivated men. When we compare the state of mind of the hunter with that of the care-taking soil-tiller, we see the vast scope and influence which this work of domestication has effected in our kind. To it perhaps more than to any other cause we must attribute the civilizable and the civilized state of mind.

Although no discreet person will venture to determine the relative weight which should be given to the influences which have made for civilization, there can be no doubt that the care of domesticated animals has been one of the most potent of these agents. Not only has this employment served to develop the motives of care-taking that result in the postponement of the momentary satisfaction of indolence or of hunger for the prospect of security or wealth to come, but it has served to arouse and broaden the sympathies given men, that humane spirit without which the best of our higher culture cannot be attained. If this view be correct, we may find in it a good reason for regretting the increasing development of cities, a reason which is more definite than the most of those which have been urged against the growth of great towns. Statistics seem to indicate that people are as healthy, as long lived, and on the whole no more given to vice and crime in a well-ordered urban life than they are on the farms. It is certainly easier to give them the formal education of the schools in the dense than in the scattered condition. There can be no doubt, however, that the practically complete separation of the most of our cities from all educative contact with the ancient companions and helpers of men brings about an omission of an element in culture that may entail serious consequences.

The question arises as to what can be done to diminish the evils which come from the total separation of a large part of our people from the humanizing influences due to the care of animals. How general this separation is may be judged from the fact that so far as I have been able to find in the manufacturing towns of Massachusetts not one child in thirty ever knew what it is to care for any creature, save those of its kind. And even in a well-conditioned place like Cambridge, the proportion of those who have any educative contact with animals probably does not exceed one in fifteen. I do not reckon the mere chance playing with a dog or cat as serving the need; the real service is when the person has a sense of responsibility for the life of the animal. To bring about this relation in the ordinary conditions of a town is usually impossible. Something can, however, be accomplished by various expedients.

In the lowest state of townspeople it is out of the question to give the children any pets whatever. Even caged birds cannot or should not be accommodated in the cheaper grade of lodging-houses. Wherever the animals are in separate houses it is often possible for children to have some contact with sympathetic animal life. In these conditions, our cocks and hens are the best creatures to rear. They are the most attractive of all our domesticated birds; they do better than any other forms of economic value in narrow conditions, and, what is of importance for the end in view, they contribute a share of food, so that a boy may have from them some experience with the economic relation of animals to men.

Some persons who have observed the advancing process of destruction of the natural world may have been brought to consider the change as in the necessary and inevitable order which comes with the higher development of man. They may welcome--indeed, some evidently do welcome--the chance that the ancient system may utterly disappear, and all the earth become fields and garden places tenanted only by those forms that man may have chosen to be his companions. To many people who have a keen impression as to the importance of man in the great economy, and no clear sense of his relation to the natural order, this possibility is doubtless attractive. It is not so to those who have gained a clear idea of the place of man and the conditions of his ongoing.

There is reason to expect that the modern gains in the cheapness and speed of transportation may before long bring about a material change in the housing of the laboring classes of our cities, so that they may be able to dwell in somewhat rural conditions. In this way we may hope to see these people once again brought where they may receive a fuller share of the influences which have served so well to lift our race to its elevated moral station. Working to the same end is the spirit which is leading many manufacturers to place their establishments in the country, where they can control the mode of life of the employees and their families. Against the growth of the factory towns with their sordid conditions, we may with pleasure set these rural workshops where the capitalists are doing the best they can to better the mode of living of the people who are under their charge. In this good work it may well be possible to include a share of contact with the soil and with domesticated animals. In this system of isolated factories we may perhaps hope to find the way out of the perplexities which the present condition of our industries have imposed on our civilization.

Up to our present half-century the process of winning animals and plants to domestication, and of improving them after they had been thus won, has been in its nature a matter of haphazard. Here and there, as men have seen creatures which promised in captivity to afford either pleasure or profit, they have endeavored to convert them to use. In some cases the effort has been made with some patience and steadfastness of purpose. If the creature yielded quickly to the needs of a new life which it was sought to impose upon him, he became a member of man's family. If its wilderness motives were strong, the effort to domesticate was soon abandoned. The greater part of these efforts to win animals and plants into alliance with our race have been made with the creatures which were native in the wildernesses about our ancestral dwelling-places. Occasionally from distant lands important gains have been made, especially among the food-giving plants; but all the animals of any importance which have been adopted by the Aryan people were originally natives of the lands in which that race has dwelt.

It is a remarkable fact that no sooner does a wild animal or plant become intimately associated with man, than it at once departs more or less widely from its ancient type. Our conquests from the vegetable world have to a great extent so far lost their original character that we can no longer determine the species from which they sprang. Botanists cannot find the wild forms which have given us the cabbage, wheat, and most other small grains, and a host of other important varieties. So, too, the origin of our dogs is as yet unsolved and bids fair ever to remain a mystery. In addition to this changed character which we observe in the forms of domesticated animals and plants alike, we note that the mental characteristics of the former undergo vast alterations. The creatures, in a way, take the tone of civilization, and to a great extent abandon those ancient habits of fear and rage which were essential to their life in the wilderness. The intellectual condition of our dogs shows us that the creatures may be progressively educated--in a word, that man may put into them something of his human quality. In the case of the dog, the longest possessed and most familiar to our households of all our captives, the mental change which has come, partly by selection, from association with man has gone so far that the species may be fairly said to have replaced its pristine motives with those which it has derived from ourselves. In many cases it has become, so far as its ways are concerned, even more man than dog.

Although the physical and mental educability of animals when brought into companionship with man is an old subject of remark, and one of the most interesting features which they exhibit, it was not until the doctrine of descent by variation of species from other related forms became established, that we had a chance to see the vast possibilities of accomplishment which are presented to us by our domesticated creatures. It is true that the breeder's art is old and that men have felt the subjugated animals to be almost like clay in the potter's hands, but except in a small and rather careless way with the dogs, little attention has been given to the development of the intelligence of these captives. The success which we have obtained with this animal has been accomplished by a selective process, but one which has been almost as blind in its operation as the choice which acts in the natural world. For thousands of years men have preferred the dogs which manifested a sympathy with them, and the result is a creature which, though derived from a very brutal ancestry, has in its way as intense affections as human beings. Now and then they have chosen deliberately to develop some mental peculiarity of the animal which would be of service in hunting, and the effect of this care is to be noted in the considerable variety and perfection of mental development which the sporting dogs exhibit. In the main, however, the interest of our dog fanciers has been limited to the physical features of the species; nothing like a deliberate effort to ascertain how far the development of their mental parts could be carried has ever been essayed. In no other field of human endeavor of anything like equal importance has there been so little understanding applied to the tasks.

Now that we are beginning to know something of the laws of inheritance, it is high time for us deliberately to consider what our relations to the organic world are hereafter to be, and how we can guide ourselves in these relations by the light of modern learning. It is in the first place clear that the subjugation of the earth which necessarily accompanies the development of civilization, inevitably tends to sweep away a large part of the organic life which is not adopted and protected by man. Already, with the mere beginnings of this culture, we find that several of the large beasts and birds and a number of plants have been destroyed. New as civilization is on this continent, it has already brought the moose and the buffalo to a point where they are on the verge of extinction, and in the Old World the wild ancestors of the horse and the bull have quite disappeared from the wildernesses. Within a few centuries the greater birds, the Dinornis and Epiornis, as well as the interesting Dodo, have vanished from the southern isles which they inhabited. In the century to come we can foresee that this process of effacement of the ancient life will go on with accelerated velocity.

It seems inevitable that man should play the part of a destroyer. It is his place to break down the ancient order determined by what we call natural forces and in its stead to set a new accord in which the economy of the earth will be in a great measure controlled by his intelligence. Even those who most keenly sympathize with the wilderness life, are not likely to object to the changes which are necessary to open the way for this new dispensation. They may fairly ask, however, that hereafter the displacement of the ancient life shall be brought about with foresight and with the exercise of the utmost care in minimizing the sacrifices which we are called on to make. Naturalists may fairly ask men to remember that each of these species which we are forced to destroy represents the toil and pains of unimaginable ages, and that when these creatures are swept away they can never be recovered. Whatever new species may come, by processes of evolution from the life which remains after we have done our will with the wilderness, we shall never see again the forms which have passed away.

It is the worst feature of the destruction which man is bringing upon the organic species that the assault is most effective on those varieties which are most interesting both from an intellectual and an economic point of view. To take only the case of the great birds which have recently been swept from the earth, we see clearly that we have with them lost precious opportunities for enlarging our understanding of nature and have at the same time been deprived of the chance to domesticate creatures which would most likely have proved of much economic value. With each of these species which disappears we lose what may be a precious chance of adding to the small store of animals or plants which may contribute to the well being of our kind. These considerations make it plain that it is our duty by our civilization, to do all in our power to save these species and at the same time to essay their domestication, for only when under the protection of man can they be regarded as insured from destruction.

The task of bringing wild creatures into our domestic fold is one of very varied difficulty. Many plants are easily reconciled to the conditions of our fields and gardens: they may be said to welcome the care of man which insures them some protection from the fierce contention with other life or with the elements to which they are exposed in their natural conditions. Only here and there is it necessary by careful breeding to develop domesticated habits to the point where the forms will endure culture. Where the task is, however, to make avail of some natural peculiarity which promises to be useful, but is not yet of economic value, it may require a hundred generations of careful selection to develop and fix desirable features. We are, however, in all cases sure in these half-animate species, the plants, that they will prove perfectly obedient to our will. It is otherwise, however, with wild animals. Here we have to deal with intelligences in which the most striking characteristic is an abiding fear of the master, and a general indisposition to submit to any other control than that of their native wild instincts. The measure in which this wilderness habit, bred of long contention with enemies, prevails in animals varies greatly. Some, as for instance the elephant, at once reconcile themselves to human association, and directly on being made slaves accept the mastery of their captors. Others, such as the zebra, remain for a lifetime possessed of their original savage nature. A large part of the labor which has been given to the work of domesticating by the breeder's art the score of mammalian species which man has won to his use has been devoted to this task of expelling the wilderness motives from these forms. The cases in which he has failed to accomplish this end are those in which the savage humor has persisted for so long a time that he has been forced to abandon his effort to subdue the stock.

It seems likely that at the present time we have acquired from the wilderness nearly all the animals which are capable of adoption by such brief and individual experiments as have won to us the species which constitute our flocks and herds. Our future gains will have to be made by far more deliberate and continuous endeavors. These tasks of the hereafter will have to be undertaken in a way which will insure a continuity of effort such as can only be attained by permanently organized associations which may continue their essays if needs be for centuries. The work should be done with two distinct ends in view: first, to determine what members of the wilderness life may be made to contribute to the needs of man; and, second, how far it is possible so to develop the intelligence of the lower animals in general as to make them better fitted for companionship with our kind. This last-named line of experiments needs to be undertaken not only with reference to varieties now wild, but also upon our most domesticated forms, for, as before remarked, we have not begun to explore the possibilities of intellectual gain, even in those species which have been the longest associated with us.

In considering a list of the creatures which might well be made the subjects of trial with a view to their domestication, we find ourselves at once embarrassed by the exceeding wealth of our opportunities. It is impossible within the limits of this article to treat, even in the catalogue way, a vast number of forms which commend themselves for experiment. Something of the richness of the field, however, may be judged by noting some of the more conspicuous forms, as we shall now proceed to do. Beginning with the insects, the lowest forms in the animal series which have proved in any sense domesticable, we note that wide as is this realm of life it offers but few opportunities such as the domesticator seeks. Of the million or more species in the group, only two, the honey-bee and the silkworm, have been won to man's use, and there is not another wild form which the naturalist can suggest as likely to prove a valuable captive. The only use which we are probably to find for these creatures is where, by some form of culture, we may induce predatory or parasitic species more effectively to do their destructive work on noxious forms of the class. So well fitted is this group for purposes of self-defence that however much man may interfere with the course of nature, he is not likely to sweep any of their multitudinous kinds from the earth, though experience clearly shows that by the methods above mentioned they may be greatly reduced.

It is among the vertebrate forms alone that we find animals which by their characteristics of body or of mind are well fitted to have an economic or social value. There alone are the qualities of flesh or of the external covering such as to make them in a high measure valuable, and the instincts of a nature to fit them for association in man's work. Even among these back-boned animals we find that the lower groups--the fishes, the amphibians, and the reptiles--promise little in the way of gains as compared with the higher groups, the birds and mammals; yet even among these inferior creatures we find certain forms which give promise of improvement under the care of man. Some of the fishes readily learn to come to any one from whom they may expect food, and they indicate in other ways that they are capable of a certain intellectual advance. The frogs and toads readily learn to recognize a master. Several of the larger members of the first-named forms could advantageously be bred so as to be very useful as food. The common hop toad of our gardens is an admirable helper in restraining the excessive development of certain slugs and insects. The tortoises and turtles contain a number of species which are edible, and many of the forms invite the breeder's care. It is, however, when we ascend in the type of vertebrates to the level of the birds that we find the great array of creatures which are worth considering as members of our civilization.

Nearly all the birds except those of prey and those which haunt the seas can easily be accustomed to man. A few of these species which have been reduced to captivity have not become sufficiently reconciled to the unnatural conditions to maintain their breeding habits. Even in these cases, however, it seems likely that in spacious aviaries, at least in climates to which they are accustomed, it will be possible to secure the continuous reproduction of the kind, on which all development by the breeder's art depends.

The ease with which most birds, except those of prey, may be reduced to domestication is due to the remarkable intensity of their sympathetic motives. In this regard the class is much more advanced than that of the mammalia to which we ourselves belong. Accustomed as they are to ceaseless and active intercourse with each other by means of their varied calls, largely endowed with the faculty of attention, and provided with fairly retentive memories, the birds are, on the average, nearer in the qualities of their intelligence to man than are many of the species in his own class. It was long ago remarked that the birds of remote islands, such as the Galapagos, which had never seen man, were at first not in the least afraid of him. It required, however, but a few generations of experience to show these creatures that the unfeathered biped was a singularly dangerous animal, and they at once and permanently adopted the habit of avoiding him. This incident of itself shows how quick birds are to learn certain large and important lessons. We see also the reverse of this education in fear in the rapid way in which birds become tame when they are secured from persecution. Wherever shooting is stopped over a considerable territory the birds rapidly become more tolerant of man's presence. Even among migratory species the individuals appear to learn that certain places where they are protected may be resorted to with safety.

Because of their freedom of flight it is in all cases difficult to bring our perching birds into such relations with the domiciles of man that they can be truly domesticated. The success, however, which has been attained in the case of the pigeons, which have been so far made captive by the change of their instincts that they never depart far from their cotes, seems to indicate that this tendency again to go wild is by no means ineradicable. In other instances it will probably disappear as it has in this by long-continued care in breeding. Our successes with the geese, ducks, and swans, all of which belong to genera characterized by the migratory habit, show how readily in the course of time the old native instincts may be subordinated to the will of man. Although the degree of the difficulty which will be encountered in taming many wild forms may be far greater than that which has been met in those which we have domesticated, there is no reason whatever to believe that in any case it will be insuperable.

While all the creatures of the wilderness may by the breeder's art be induced to vary in the conditions of captivity, the birds have shown themselves more plastic in our hands than any other animals. In almost every brood we find individuals possessing marked peculiarities of form or plumage. In their mental qualities also there is a like range of variation. Seizing upon these, the fancier can guide the quick succeeding generations so as to cause the form to depart in the course of a few years very far from its original aspect. With each step in this succession of changes the readiness with which the species responds to selective care increases. The results which have been attained in our barnyard fowl and with the pigeons show how admirably these creatures are fitted to obey the will of man when he has a mind to take charge of their destiny.

Perhaps the greatest conquests which we have yet to make among the birds will be won from the species which have the habit of dwelling mainly or altogether upon the ground. These, as experience shows, can be more readily brought to the uses of man than the species which are free by their strong wings to wander through the realms of air. There are very many of these ground birds the domestication of which has never been fairly essayed. There are perhaps a hundred species which in one part of the world or another might afford valuable additions to our resources, those of ornament or of economy, and yet within three centuries only one of these, the turkey, has been brought to the domesticated state. The greater part of our game birds, such as the quail, pheasants, and partridges, though they appear on slight experiments to be untamable, could probably by continuous effort be reduced to perfect domestication. For ages they have been harried by man in a manner which has insured a great fear of his presence. We have indeed through our hunting instituted a very thorough-going and continuous system of selection which has tended to affirm in these creatures an intense fear of our kind. Only the more timorous have escaped us, and year after year we proceed to remove with the gun the individuals which by chance are born with any considerable share of the primitive tolerance of man's presence. It is not to be expected that the chicks of these species will at once accept relations with our kind. The domestication of many of these forms is to be desired, not only on account of the excellent quality of their flesh, but because of their beauty and the charm which their quick intelligences afford them. Whoever has watched them in their care of their young or their other social habits has observed features which indicate a possible development under domestication perhaps greater than that which we have attained in any other of our feathered captives.

It seems most important that experiments in the further domestication of birds should be first addressed to certain, large ground forms which are now in more or less danger of extinction. The newly instituted industry of ostrich farming has probably insured this the noblest remnant of the old avian life from destruction; but the emu and the cassowary are still among the diminishing and endangered forms which unless taken into the human fold are likely soon to pass away. The brush turkey and the bower bird of Australia, two of the most curious inhabitants of that realm of strange life, appear to have qualities of mind and body which would make them readily domesticable and which would cause them to be among the most interesting of our feathered captives.

Among the aquatic birds there are many species which are as promising subjects for domestication as any which have been made captive; these if subjugated would prove great additions to our resources of ornament and use. Thus the eider duck, so well known for its wonderful soft down which is plucked from the breast to make a covering for the eggs, though a marine species, would prove domesticable at least on the seashore of high latitudes. There are many other varieties of the family, such as the canvas-back which is so highly esteemed for its flesh, that would likewise afford very interesting subjects for experiment.

The wading birds are characteristically very wild and range over a wide field; yet the flamingoes, the herons, and their kindred could probably be brought into at least as near an approach to reconciliation with man as their relations the storks. The comfortable relations which have been established between the last-named species and humankind in northern Europe is probably in nowise due to the peculiarly tamable nature of the bird, but rather to the fact that certain superstitious fancies on the part of the featherless biped led him to protect the feathered visitor of his roofs and chimneys. Should it be desirable to break up the habit of migration in these or other birds which are now accustomed to range up and down the meridians, there seems no reason to doubt that the change could be accomplished with the same ease that it has been in the case of the tamed geese and swans. Experience has shown that with these forms, which probably have not been associated with men for more than three or four thousand years, the migratory instinct, which appears one of the strongest of motives, has utterly disappeared. Not only do they no longer heed the cries of the wild birds of their kind as they fly away on their annual journeys, but they have, through the changes in form induced by their quiet life, lost the power to rise far above the earth. They are even more effectively tamed than are their captors.

Owing to their singularly perfect protection against the cold, and also perhaps to the quickness of their wits, birds are more readily transferable from one clime to another than are any other animals. The feathered tenants of our barnyards are, except perhaps the aquatic species and the turkey, all from the tropical realm. Experiments with various other wild forms go to show that there are very many other tropical species which will prove to have an equal tolerance of high latitudes. If this be true we may fairly look to the domestication of the varied bird life of the equatorial regions for the enrichment of our northern lands. Even when it may not be desirable to bring these species to the state of complete subjugation they may be introduced on something like the terms which have been given and accepted in the case of the so-called English pheasant, which has brought to the high north of Britain and some parts of this country an element of grace which is afforded by no indigenous form of North America or Europe. There are hundreds of beautiful tropical species which await reconciliation with men; they have that quality of sympathy which affords the natural foundations for the contract, but this has in no case been availed of except when the creatures, in addition to their aesthetic charm, have possessed some economic value. There as elsewhere in the matter of domestication the commercial motive has controlled our action.

In forming our societies as we are in time to do, account must be taken of the sympathetic value of its elements, reckoning among these the animals which the system brings in contact with men. Much of the culture which has served to lift our race above its ancient savagery has been derived from the influence of domesticated animals; in proportion as these creatures have sympathetically responded to our care we have been thereby educated and our spiritual development advanced. So far as in our further choice of animals which are to be associated with ourselves we are guided by a desire to extend this work, we may well turn our attention towards the birds, for in that group we may find a greater number of species which have attained the physical beauty which attracts and the mental qualities which may endear them to mankind. They can give us nothing that can ever come so close to us as the dog--the unique gift of the wilderness--but they may afford a host of forms to enrich our lives.

The mammals, because they are, in qualities of body and mind, nearer to us than the members of any other class of animals, afford the most promising field from which to make selections for future domestication. In an economic sense it seems unlikely that any very great profit can be attained by the subjugation of any of the mammalian species which are still wild. Civilized people have been so long in contact with the life of all the continents, and have ever been so hungry for gain, that they have already essayed about every experiment in subjugating the larger wild beasts which appears to be very promising. Still there are certain cases where there have been no trials and others where the failure to tame particular species has been due to hindrances which systematic labor may possibly overcome. It will therefore be well to glance at the array of the wild forms which afford some prospect of success in the hereafter, including under the title of successes those kinds which may contribute not only to immediately measurable wealth, but the aesthetic satisfactions as well.

Beginning with the lowlier group of mammals we find in the base of the series the ornithorhynchus and its allies, creatures which have nothing to recommend them but their exceeding organic peculiarities that render them attractive to the naturalist, but which are not likely to win them a place in the affections of men in general. As these species are most inoffensive as well as interesting, and as they are now confined to a portion of Australia, they might well be made the subject of some human care which would stop short of domestication. They might be transplanted to other continents and thereby given a larger field for variation as well as a chance to exhibit their features in a wider field. Among the pouched mammals, especially in the species of kangaroo, there are forms which commend themselves as very fair subjects for taming. They are of considerable size, their flesh is palatable, and their hides useful for leather; they breed rapidly, live on a poor herbage, and are, for wild animals of like strength, very inoffensive. Moreover, though relatively invariable both in mind and body, they exhibit sufficient individual peculiarities to indicate that the breeder's art could, in a short time, bring about considerable changes such as have been effected in other species, changes that would increase the value of these animals. As far as aesthetic or sympathetic relations are concerned, the pouched mammals have nothing to give us; they are, as befits their lowly estate, among the least graceful of their class; they are also little interesting in their mental qualities, being about the stupidest of our kindred.
