Domesticated Animals.

INTRODUCTION

One of the effects of the modern advance in natural science has been greatly to increase the attention which is devoted to the influences that the conditions of diverse peoples have had upon their development.

Man is no longer looked upon, as he was of old, as a being which had been imposed upon the earth in a sudden and arbitrary manner, set to rule the world into which he had been sent as a master. We now see him as one of the myriad species which has won its way by powers of mind out of darkness and the great struggle to the place of command. The way in which this creature, weak in body and exceedingly dependent on his surroundings, has in the modern geologic epoch come forth from the ma.s.s of the lower animals, is by far the most impressive and as yet the most unexplained phenomenon which the geologist has to consider. It is not likely that the marvellous advancement can be accounted for by any single cause; it is probably due, as are most of the great evolutions, to the concurrence of many influences; but among these which make for advance, we clearly have to reckon the animals and plants which man has learned to a.s.sociate with his work of the household and the fields.

Although certain species of insects, particularly the ants, have the well-developed habit of subjugating certain creatures of their own family, man is the only vertebrate that has ever adopted the plan of domesticating a variety of animals and plants. The beginnings of this custom were made in a very remote time, and for long ages the profit which was thereby gained appears to have been but slight. Gradually, however, races, owing to their masterful quality and to the opportunities which were offered by the wild life about their dwelling places, obtained flocks and herds. In the group of continents commonly termed the old world, where there were several ancient primitive peoples of innate ability, and where there were many species of larger mammals which were well fitted for domestication, the advance in social development went on rapidly. In the new world, though the primitive races contained tribes of much ability, there was practically no chance for the people to add to their strength by the subjugation of beasts of burden, or to their food resources by the adoption of various animals which could be used for the needs of food or raiment. The advance of men when they have obtained valuable domesticated animals, and their failure to win a high station where the surrounding nature denied such opportunities, go far to prove the bearing of this accomplishment in the development of peoples.

A little consideration makes it evident to us that the advance of mankind above the original savage state is in several ways favored by the possession of domesticated animals. In the first place, each creature which is adopted into the household or the fields usually brings as its tribute a substantial contribution to the resources which tend to make the society commercially successful. When we consider the enlargements of resources and the diversification of industries which rest upon the adoption of any one of these animals--as, for instance, the horse--we see in a way what the possession of domesticated animals and plants really means, and are in a position to conceive, though at best but dimly, what the scores of these captive species have done for us. We recognize the fact that while, under almost any conditions, a certain manner of advance above the most primitive savagery is possible to a naturally able people, this on-going cannot lead any distance unless the folk have other help than their own weak bodies can give them. It is hardly too much to say that civilization has intimately depended on the subjugation of a great range of useful species.

It would be interesting to trace, if we could, what share the several domesticated animals have had in the development of the human races; but this task is not to be done. We can, however, discern that the Arab without the camel and the horse would not have found the place in history which he has filled, and that our own race could not have attained its place save for the aid which the horned cattle, sheep, and a host of other helpers which we have pressed into service, have afforded. These economic gains have to be judged in ma.s.s, they cannot be reckoned in detail. When we have made the best account of them we can, there remains another cla.s.s of influences, the value of which, though evidently great, is yet harder to reckon; these arise from the education which has been attained through the care of these adopted creatures.

Among savages the great need is a training in forethoughtfulness; all primitive peoples are like children, they live in the interests of the day; the cares of the seasons to come, or even of the morrow, are not for them. The possession of domesticated animals certainly did much to break up this old brutal way of life; it led to a higher sense of responsibility to the care of the household; it brought about systematic agriculture; it developed the art of war; it laid the foundations of wealth and commerce, and so set men well upon their upward way.

Moreover, the use of domesticated animals of the better sort enabled the more vigorous and care-taking races to gain the strength which led to their advancement in power to a point where they were able to displace the lower and feebler tribes. In other words, the system of domestication has provided a method by which those peoples who were fitted to develop the qualities which make for civilization could advance; it has provided the opportunity for selection.

Of all the influences which have been exercised on man by the care of his flocks, herds, and droves, perhaps the most important is that which has arisen from the broader development of his sympathies. The savage may be defined as a man who cares only for his family and his tribe; the civilized man as one whose kindly interest extends to mankind and beyond to all sentient beings. In the development of this altruistic motive the care of the dependent species has evidently been most effective. We note that the peoples who have attained the first upward step in the a.s.sociation with domesticated animals are in their quality, so far as tested by literature and history, much above the mere savage. With the care of the flocks we find a.s.sociated poetry, the first notes of higher religious motives, and a largeness of the sympathetic life which is favored by the nature of the occupation. Where the nomadic habits of the original shepherds pa.s.s into the more sedentary state of the soil tiller, the element of personal care and the affection and the consequent education of the sympathy were increased. Men had now to care for half a dozen or more kinds of animals; they had to learn their ways, in a manner to put themselves in their places and conceive their needs.

Thus the life of a farmer is a continual lesson in the art of sympathy; with the result, certainly in part due to this cause, that there is no cla.s.s of people from whom the brutal instincts of the ancient savage life which we all inherit have been so completely eradicated.

It is perhaps too much to attribute the advance of the agricultural cla.s.ses of our civilized peoples, in all that serves to remove them from the brutality of their savage ancestors, altogether to the nature of their work--to the very large element of kindly care for which it calls, and which is the price of success in the occupation. Yet when we note the immediate way in which the people bred in cities, under circ.u.mstances of excitement are wont to behave like savages of the lower kind, showing in their conduct a lack of all sympathetic education, and contrast their behavior with that of their kinsmen from the fields--we see essential differences in character which cannot well be explained save by the diverse natures of the training which the men have received.

Thus in the French Revolution, the baser, more inhuman deeds were not committed by the peasants, who had been the princ.i.p.al sufferers under the regime which was overthrown, but by the people of the great towns who had been less oppressed by the iniquities of the old system of government.

If it be true--as my personal experiences and observations lead me firmly to believe is the case--that man's contact with the domesticated animals has been and is ever to be one of the most effective means whereby his sympathetic, his civilized motives may be broadened and affirmed, there is clearly reason for giving to this side of life a larger share of attention than it has received. So far the presence of these lower creatures in our society has generally been accepted as a matter of course. Sentimentalists, after the fashion of Laurence Sterne, have dwelt upon the imaginary woes of the creatures. a.s.sociations of well-meaning people have endeavored to diminish the cruelty which people of the towns, rarely those bred on the soil, often inflict upon them. It seems, however, desirable that we should place this consideration upon a plane more fitting the knowledge of our time. It should be made plain, not only that the success of our civilization depends now as in the past on the cooperation which mankind has had from the domesticated animals, but also that the development of this relation is one of the most interesting features in all history. On through the ages of the geologic past comes this great procession of life, in the endless succession of species whose numbers in the aggregate are to be reckoned by the scores, if not by the hundreds of millions. Until this modern age, the throng goes forward blindly, groping its way towards the higher planes of life.

At length certain of the more advanced forms attain to a measure of intellectual elevation. Still, for all this advance, the life is not organized so as to attain any large ends; no society arises from it.

Suddenly, in the last geological epoch, man, the descendant of a group which like all others had led the narrow life of the preparatory ages, appears upon the scene. At first, and in his lower human estate, his position was not noticeably higher than that of his kindred, but there was in him the seed of a great unlikeness, of very new things, in that his desires had an element of the unlimited which was to grow apace, and in time to make him greedy of on-going. As this innovating creature sought for agents of power in the wilderness about him, he blindly laid hands upon such of the fellow tenants of the wilds as might serve his immediate needs. This species, both animals and plants, endowed with the capacity for variation, the plasticity which is in general a characteristic of all organic forms, were early led by their new master, as of old they had been guided by the old organic laws. They changed according to his choice, abandoning their ancient ways for the novel paths of civilization. With this a.s.sociation of the higher forms of the earth under the leadership of man, there began an entirely new and unprecedented condition of the world's affairs. In place of the ancient law of nature there came the control of our species which had been, in a way, chosen to be the overlord of life.

At first, the number of species of animals and plants which man brought under his control was very limited; it was indeed confined to those which might readily be subjugated to meet immediate needs. Gradually, however, the list has been extended until it included thousands of forms, which, while they meet no need such as the savage recognizes, are gratifying to the taste or the ambitions of civilized peoples. These aesthetic devices, or those of necessity, are advancing so rapidly that each generation sees hundreds of new animal and plant species added to our living collections, so that our plant and animal gardens now contain a large share of the more attractive forms which are to be found in the various geographical realms. Our tilled fields yield perhaps a hundred times as many varieties of plants as they did in the earliest historic agriculture. The advance in the process of domestication is not so rapid as regards the animal kingdom as it is with the realm of plants, and this mainly for the reason that animals have a will of their own which has to be bent or broken to that of man. Still it goes on apace. We of to-day have at our command many times the number of sentient species contributive to our pleasure or profit that had been made captive at the beginning of our era. Naturally, in the early days of domestication, men brought under their control the greater number of the animals which gave promise of utility. As no new species of any economic importance have been created within the last geologic period, the field for the extension of economic domestication has of late been very limited. But the realm of sympathetic appreciation, unlike the economic, knows no definite bounds, and promises in time to bring all the more important organic forms under the care of the sympathetic and masterful being who has been chosen as the ruler of terrestrial life.

We thus see that the matter of domesticated animals is but a part of the larger problem which includes all that relates to man's destined mastery of the earth--a mastery which he is rapidly winning. It means that, in time, a large part of the life of this sphere is to be committed to his care, to survive or perish as he wills, to change at his bidding, to give, as other subjugated kinds have done, whatever of profit or pleasure they may contribute to his endless advancement. From this point of view our domesticated creatures should be presented to our people, with the purpose in mind of bringing them to see that the process of domestication has a far-reaching aspect, a dignity, we may fairly say a grandeur, that few human actions possess. If we can impress this view, it will be certain to awaken men to a larger sense of their responsibility for, and their duty by, the creatures which we have taken from their olden natural state into the social order. It will, at the same time, enlarge our conceptions of our own place in the order of this world.

In the following pages little effort has been made to present those facts concerning domesticated animals which would commonly be reckoned as scientific. The several essays which, in larger part, were separately printed in Scribner's Magazine, are intended for those persons who, while they may not care to approach the matter in the manner of the professional inquirer, are glad to have the results which naturalists have attained, so far as they may serve to extend knowledge of things which lie in the field of familiar experiences. To the text as it at first appeared, numerous additions have been made, and the concluding chapters, on the Rights of Animals, and on the Problem of Domestication, are new. In them an effort is made to direct attention to the importance of the problem of man's relation to the lower life which is about him, and which in the future far more than in the past is to be helped or hindered by his rule. Our life is made up of large problems; but there seem few that are greater than this, which concerns our duty by the creatures that share with us the blessings of existence, and over which we have come to rule.

THE DOG

Ancestry of the Domesticated Dogs.--Early Uses of the Animal: Variations induced by Civilization.--Shepherd-dogs: their Peculiarities; other Breeds.--Possible Intellectual Advances.--Evils of Specialized Breeding.--Likeness of Emotions of Dogs to those of Man: Comparison with other Domesticated Animals.--Modes of Expression of Emotions in Dogs.--Future Development of this Species.--Comparison of Dogs and Cats as regards Intelligence and Position in Relation to Man.

It is an interesting fact that the first creature which man won to domesticity was made captive and friend for the sake of companionship rather than for any grosser profit. The dog was, the world over, the first living possession of man beyond the limits of his own kindred. He has been so long separated from the primitive species whence he sprang that we cannot trace with any certainty his kinship with the creatures of the wilderness. Like his master he has become so artificialized that it is hard to conjecture what his original state may have been.

Naturalists are much divided in opinion in all that relates to the origin of our ancient and common domesticated animals; and this for the reason that the longer a creature has been subjected to the change-bringing conditions of our fields and households, the further it has departed from the parent stock. This difficulty is naturally the greatest in the case of the dogs, for the reason that they have been longer and more completely under the control of man than any other of the lower animals. Some students of the problem have inclined to the opinion that the dog is a descendant of the wolf; the whelps of this species, it is supposed, were captured by primitive men and brought under domestication. Savages, like children, are much given to bringing the young of wild animals to their homes; if the conditions are favorable they will care for these captives, even if the charge upon their resources is tolerably heavy. With most primitive people, however, life is so vagarious and starvation so recurrent that they are not apt to retain their pets long enough to establish domesticated forms. Thus, among our American Indians, though they show fondness for wild creatures as much as any other people, no species save the dog ever became permanently a.s.sociated with their tribe. It is, however, possible, that in some sedentary group of savages the work of domesticating the ancestors of the dog, even if they were wolf-like, was accomplished.

The difficulty of this view is that even with the high measure of care which the conditions of civilization permit us to devote to the effort, it has been found impossible to educate captive wolves to the point where they show any affection for their masters, or are in the least degree useful in the arts of the household or the occupations of the chase. They are, in fact, indomitably fierce and utterly self-regarding. It seems unreasonable to believe that any savage would have found either pleasure or profit from an effort to tame any of the known species of wolves. Moreover, the fact that dogs show little or no tendency to revert to the form and habits of their brutal kindred, or to interbreed with them, is clearly against the supposition that there is any close relation between the creatures.

[Ill.u.s.tration: Greyhound after "the Kill"]

Yet other speculative inquirers have sought the origin of the dog through the admixture of the blood of several different species, the wolf and the jackal being, perhaps, the princ.i.p.al or the only components of the hybrid stock. Here, too, the evidence of nature is against the supposition. No one has ever succeeded in hybridizing the wolf and the jackal, nor do our dogs show any more tendency to revert to the jackal than to the wolf. They meet their tropical relative with as much animosity as is proper, or at least customary, in the intercourse of allied yet distinct species. In fact, all the indices by which we are able to carry back the history of other domesticated animals to their primitive or even extinct ancestry, fail in the case of the dog. When the stock is allowed to go as nearly wild as they can be induced to become, we do not find that they thereby approach to any known wild form. It therefore seems reasonable to betake ourselves to another basis for the natural history of the dog, which has not yet been made a matter of much inquiry, but which promises to afford us more substantial truth than the conjectures which we have just considered.

We should, in the first place, note the fact that the ancestors of our more important domesticated animals, those which have been longest in subjugation, have commonly disappeared from the wild state--the species, except for the cultivated forms, having gone into the irrecoverable past. This is the case with the wild kindred of our bulls, horses, sheep, and camels, there probably being none of the original wild species of these groups now living, except those which have been more or less completely subjugated by man, and then have returned to the wilderness. The fact is, that with any large mammal the domestication of the species tends to bring about the destruction of the remaining wild forms. If we go back in fancy to the time when the dog was taken in from the wilderness, we readily perceive how certainly the subjugated individuals would have mingled with their wild kindred, so that either the wild would have become tame or _vice versa_. The same incompatibility which exists between slavery and freedom in our own species in any given territory may be said to hold in the case of captive animals. It is particularly on this account that I am disposed to think that our races of dogs have been derived from one or more original species of truly canine ancestors, the wild forms of which have long since disappeared from the earth.

[Ill.u.s.tration: St. Bernard]

Although there are no species of wild dogs now in existence to which we can refer the origin of our household friends, there are several known to us only in their fossil state, from which they may possibly--indeed, we may say probably--have been derived. These creatures are, of course, represented only by their skeletons, and even these remains have only been found in an imperfect state of preservation. It is evident, however, that these extinct species, or at least certain of them, lived down to the time when man had come upon the earth, and was beginning to speculate on his surroundings for such company and help as he might win therefrom. It may interest the reader to know that a species of American dog existed in the Southern Appalachians down to a very recent time--recent, at least, in a geological sense. The remains of one of these animals were found by the writer in a cave in East Tennessee, near c.u.mberland Gap. From the fragments of the skeleton, Mr. J. A. Allen has described the species. The animal appears to have been of moderate size, and, from the position of the bones, it seems tolerably certain that it lived but a few centuries ago.

It is clearly a reasonable supposition that some of these primitive canine species may have been far more domesticable than the existing kindred of the dog--the wolves, foxes, jackals, or hyenas--differing from their fiercer kindred much as the zebras do from the wild a.s.ses, the one form being utterly undomesticable, and the other lending its back almost willingly to the burdens which man chooses to impose. It seems likely that this primitive species--perhaps more than one--whence the dog sprang was not a very vigorous or widespread form; else, as before remarked, a savage would have found it impossible to keep his half-tamed creatures from rejoining their wild kinsmen. Thus, if a man should in this day succeed in taming wolves, in a region where they were plenty, to the point where they began to abide his presence, or even to have some slight affection for him, the call of nature would be likely to lead them back to reunion with their kind.

It seems pretty certain that the first steps in the domestication of the dog must be attributed not to any distinct purpose of acquiring a useful companion, but to that vague instinct which leads children to make captives of any wild animals with which they come in contact. The fancy for pets is not only common to all mankind, civilized and savage alike, but is clearly exhibited in many of the mammals below the level of man.

Almost every one has observed cases where dogs, cats, and horses have become attached to some creature of an alien species with which they have been by chance thrown in contact. The higher the grade of the intelligence, the more sympathetic with other life the animal is likely to become. Thus the elephants, whose natural endowments in the way of intelligence are perhaps superior to those of any other wild creatures, are, when brought into captivity, curiously p.r.o.ne to form attachments to human beings. Savages appear to make but little use of their dogs in hunting. In fact, those peculiar combinations of instinct and training which we find in our hounds, pointers, setters, and other dogs which have been bred to serve the purposes of sportsmen, have been acquired but slowly, and are of no value except where the search for game is carried on under what we may term civilized conditions. The dog of the savage is in all countries much like his master--a creature with few arts and unaccustomed to subdue his rude native impulses.

[Ill.u.s.tration: Spaniel Retrieving Wild Duck]

It seems most likely that for ages the princ.i.p.al use of the dog which dwelt about the camps of the primitive people was found in the reserve food supply which they afforded their thriftless masters. When the hunting was successful the poor brutes had a chance to wax fat, and even in times of scarcity they managed to pick up enough food to keep them alive. When their masters were brought to a state of famine they were doubtless accustomed, as are many savages at the present time, to eat a portion of their pack. In the early conditions of humanity there was no other beast which could be made to serve so well this simple need in the way of provender. The dog is, in fact, the only animal ever domesticated which can be trusted through his own affections alone to abide with his master in the endless changes of camp and the rapid movements of flight and chase which characterized men before their housed state began. In a certain curious way the use of dogs for food has served greatly to advance the development of these captives.

When the savage was driven to feed upon his dogs he was naturally more willing to sacrifice the least intelligent and affectionate of them, delaying, to the point of extremity, the time when he would kill those which had endeared themselves to him. In this way for ages a careful though unintended process of selection was applied to these creatures, and to it we may fairly attribute, as many considerate naturalists have done, a large part of the intellectual--indeed, we may say moral--elevation to which they have attained.

When the place of the dog as the first and most intimate companion of man was affirmed in the rude way above described--when the savagery to which he was at first made free gradually enlarged to civilization, a number of special uses were found for the peculiar capacities of the creature. These varied in the different parts of the world, according to the peculiarities in the conditions of the masters. In high lat.i.tudes, where the ground is snow-covered during the winter season, dogs were used, as they are to this day, in dragging sleds. They were, indeed, perhaps the first animals which were harnessed to vehicles. When they were brought to serve this definite end, we may well believe that the stronger and more enduring individuals were spared in times of dearth for the reason that they were almost indispensable to their masters, and even the little forethought which we find among primitive peoples would lead to their preservation. Here again, doubtless, came in the process of unintended selection which has made the Esquimau sled-dog one of the most remarkable varieties of his kind.

Perhaps the most interesting of the early variations induced among dogs is that which has arisen from the pastoral habit. We do not know when this custom of keeping sheep in large flocks was first inst.i.tuted, but it is evidently of exceeding antiquity, probably far older than the pyramids of Egypt. The custom could hardly have been inst.i.tuted without help of the shepherd's mate, the sheep-dog.

Although the creatures of this breed are probably in form very near to the original wild species whence our canines came, the variety has as regards its instincts been, by a process of education and selection, led very far away from the original stock.

The wild forefathers of this species were clearly natural born sheep-slayers, and the motive abides to this day in all the breeds which have the strength to a.s.sail our unresisting flocks. The spirit is so ingrained that even the most civilized of our house-dogs, which may for generations never have tasted blood and which show no disposition to attack the other animals of the barn-yard, cannot be trusted alone with sheep. When two or more of them are together the old instincts of the wild pack return, and they will slay with insensate brutality until they are fairly exhausted with their fury. Their behavior on such occasions reminds one of the actions of their masters when possessed with the blind rage of a mob. Yet in the shepherd-dog we find this ancestral motive, once a large part of the life of the creature, so overcome by education and selection that they will not only care for a flock with all the devotion which self-interest can lead the master to give to the task, but they will cheerfully undergo almost any measure of privation in order to protect their charges from harm. The annals of shepherd districts, especially those where winter snows fall deeply, as in Scotland, abound in anecdotes of a well-attested nature which show how profoundly the dogs which tend the flocks are imbued with the love of the animals committed to their care. This affection is more curious for the reason that it is never in any measure returned by the sheep. To them the custodian is ever a dreaded overseer. He seems to bring to them nothing but the memories of danger derived from the experience which their species acquired in far-away times.

It is very interesting to note the behavior of a young shepherd-dog when he is first brought in contact with a flock. It is easy to see that he has an amazingly keen interest in the sheep. He regards them with an attention which he gives to no other living things, except perhaps his master. Out of a litter of well-bred pups belonging to this variety, the greater part will at once a.s.sume a curatorial att.i.tude toward a flock.

They will show a disposition to keep them together, and will seize on an individual only in case he undertakes to break away. They will generally use no more force than is necessary to reduce the recalcitrant to order. They arrest him by catching hold of the leg or fleece, and rarely seize hold of the throat, which other dogs, led by their inherited instincts, are apt at once to a.s.sail. Very rarely does a shepherd-dog of good ancestry, even at the outset of his career, attack a sheep in a way which shows that the ancient proclivities have been revived in his spirit. Even then a little remonstrance, or at most a slight castigation, is pretty sure to turn him from his evil ways. If we could measure in some visible manner the psychic peculiarities of animals, we would be led to regard this great change in the instincts of the dog, which has been brought about by his use in herding, as perhaps the most momentous transformation which man has ever accomplished in any creature, including himself; for none of our own inherited savage traits are so completely sublated at the time of our birth as is this old and sometime dominant slaying motive in the shepherd-dog.

With the advancing differentiation of human occupations and amus.e.m.e.nts, our breeds of dogs have, by more or less deliberate selection, been developed until by form and instincts they fit a great variety of purposes. Some of these pertain to industrial work, but the greater portion are related to the sports or fancies of men. The turnspit was bred for its short legs and small, compact body, and was serviceable in those treadmills of the hearth which have long since pa.s.sed out of use, but which were for centuries features in our kitchens.

[Ill.u.s.tration: Bull-Dog]

The ma.s.sive type of bull-dogs, characterized by heavy frames and an indomitable will, appears to have been brought about by a process of selection having for its unconscious end the development of a breed which should render the herdsman of horned cattle something like the a.s.sistance which the shepherd-dog gave to those who had charge of flocks. In the more primitive state of our bulls and cows the creatures were much wilder than at present, and were generally kept, not in enclosed pastures, but on unfenced ranges. In these conditions the care taken needed the help which the ancestors of our modern bull-dog afforded. The tasks which the animal was called on to perform were of a ruder nature than those which were allotted to the shepherd-dog. Their business was to conquer the unruly beast. They were taught to seize the muzzle, and by the pain they thus inflicted they could subdue even the fiercer small bulls of the ancient type of form. From this original use the cattle-dogs were turned to the brutal sport of bull-baiting, a rude diversion which was indulged in by our ancestors for centuries, and has only disappeared in our less cruel modern days. Bred for the bull-ring, these dogs acquired the formidable strength and ferocity under excitement which made their name a terror and their qualities a satirical embodiment of the ruder traits which characterized the British folk.

The training which inst.i.tuted the breed of bull-dogs was evidently much less continuous and effective than that which developed the shepherding variety. The use for the creature in the care of herds has pa.s.sed away. In the older parts of the world cattle are kept only in enclosures; and where, as on our frontier, they still range over unbounded fields, they are guarded by hors.e.m.e.n who do not need the a.s.sistance of dogs to control the movements of the herds. No longer serviceable either in economies or sports, the breed of true bull-dogs is rapidly disappearing. As we may often observe in other fields of development, the peculiarities of this breed are now under the control of fancy, and the blood is being led far away from its old characteristics. The bull-terrier and other varieties, which retain something of the form and of the solemn demeanor which characterized their ancestors, but which are too small to a.s.sail horned cattle, mark the vanishing stages of this great stock, which will soon be known only in memory. The history of this peculiar herd-dog shows us how marvellously pliant the body and mind of this species has become under the conditions of civilization. The rude process of unconscious selection, acting without steadfastness of purpose or rationally developed skill, serves to sway the qualities of the animal this way or that to meet the ever-changing requirements of use or fancy. A similar selection in the case of our horned cattle has within a few centuries converted the cows into mild-mannered and sedentary milk-making machines, and has deprived the bulls of the greater part of their ancient savage humor. Owing to this change in the quality of their a.s.sociates in captivity the dogs have also been led into great variations. The same type of interaction may be traced again and again in the isolated part of the world enclosed within our fences, as well as in the free realm of the wildernesses. All the individuals in the great host of life affect each other as do the soldiers of a well-organized army in the movements of a battle.

The shepherd-dog, the turnspit, and the bull-dog are the three remarkable variations of the canine blood which were brought about by a process of training and selection unconsciously directed to the inst.i.tution of breeds suited to special economic ends. The other varieties of dogs have been shaped more distinctly for purposes of amus.e.m.e.nt or for the indulgence of mere fancy. The several varieties of hounds, harriers, beagles, pointers, setters, terriers, etc., have been designed to meet a dozen or more variations in the conditions of the chase. The marvellously complete way in which special peculiarities have been developed in mind and body makes this field of domestic culture the most fascinating subject of inquiry to the naturalist. The ordinary fox-hound has had his inheritances determined so as to fit him for pursuing a small animal which can rarely be kept in view during its flight, and which can only be followed by the odor it leaves in its trail, so these creatures run almost altogether under guidance of their sense of smell. The stag-hound, on the other hand, pursues a relatively large animal which cannot well be followed by the nose, at least with any speed; they therefore trust almost altogether to vision in their chase. The packs which hunt otters have developed the swimming habit and an array of instincts which fit them especially for this peculiar sport. If s.p.a.ce allowed we could note at least a dozen divisions of the group of hounds or chasing dogs, each of which has developed a peculiar a.s.semblage of qualities, more or less precisely adapted to some particular game.

[Ill.u.s.tration: Fox-Hound and Pups]

Perhaps the most special adaption which man has brought about in his domesticated animals is found in our pointers and setters. In these groups the dogs have been taught, in somewhat diverse ways, to indicate the presence of birds to the gunner. Although the modes of action of these two breeds are closely related, they are sufficiently distinct to meet certain differences of circ.u.mstances. The peculiarities of their actions, it should be noted, are altogether related to the qualities of our fowling-pieces. These have been in use, at least in the form where shot took the place of the single ball, for less than two centuries, and the peculiar training of our pointers and setters has been brought about in even less time. It seems likely, indeed, that it is the result of about a hundred and fifty years of teaching, combined with the selection which so effectively works upon all our domesticated creatures. It thus appears that this peculiar impress upon the habits of the hunting-dog is the result of somewhere near thirty generations of culture.

[Ill.u.s.tration: Pointer Retrieving a Fallen Bird]

Although, as has been often suggested, the pointing or setting habit probably rests upon an original custom of pausing for a moment before leaping upon their prey, which was possibly characteristic of the wild dog, it seems to me unlikely that this is the case, for we do not find this habit of creeping on the prey among our more primitive forms of dogs nor the wild allied species as a marked feature. All the canine animals trust rather to furious chase than to the cautious form of a.s.sault by stealthy approach and a final spring upon their prey, as is the habit with the cat tribe. Granting this somewhat doubtful claim that the induced habits of these dogs which have been specially adapted to the fowling-piece rest upon an original and native instinct, the amount of specialization which has been attained in about thirty generations of care remains a very surprising feature, and affords one of the most instructive lessons as to the possibilities of animal culture.
