Domesticated Animals Part 4

As a flesh producer, particularly in sterile fields, sheep are more valuable than our horned cattle. They mature more rapidly, attaining their adult size and reproducing their kind in less than two years, so that in many parts of the world it is possible to obtain a larger quant.i.ty of flesh from poor pasturages with sheep than with any other of our domesticated animals. Their princ.i.p.al value, however, has been from the means they afforded whereby men in high lat.i.tudes have obtained warm clothing. Before the domestication of these creatures, peoples who had to endure the winter of high lat.i.tudes were forced to rely upon hides for covering--a form of clothing which is clumsy, uncleanly, and which the chase could not supply in any considerable quant.i.ty. Owing to its peculiar structure, the hair of the sheep makes the strongest and warmest covering, when rendered into cloth, which has ever been devised for the use of man. The value of this contribution is directly related to the conditions of climate. In the intertropical regions the sheep plays no part of importance. In high lat.i.tudes it is of the utmost value to man. No other of our domesticated creatures, except the camel, is so specially adapted to the needs which peculiarities of climate impose upon their possessors.

The relations of the goat to mankind are in certain ways peculiar. The creature has long been subjugated, probably having come into the human family before the dawn of history. It has been almost as widely disseminated, among barbarian and civilized peoples alike, as the sheep. It readily cleaves to the household, and exhibits much more intelligence than the other members of our flocks and herds. It yields good milk, the flesh is edible, though in the old animals not savory, and the hair can be made to vary in a larger measure than any of our animals which are shorn. Yet this creature has never obtained the place in relation to man to which it seems ent.i.tled. Only here and there is it kept in considerable numbers or made the basis of extensive industries. The reason for this seems to be that these animals cannot readily be kept in flocks in the manner of sheep. They are only partly gregarious, and tend to stray from the owner's keeping. There seems reason also to believe that they cannot easily be made to vary in other characteristics except their hairy covering at the will of the breeder, and so varieties cannot be formed, as is the case with sheep, to suit each peculiarity of soil and climate. Thus in Europe, where it would be easy to name a score of distinct breeds of sheep, each peculiarly well suited to the conditions of the country where it had been developed, the goats are singularly alike. The original stock of these creatures appears to have been adapted to feeding on the scant herbage which develops in rocky and mountainous countries. They do not seem able to make the perfect use of the resources of a pasture which sheep do.

These inherited peculiarities in feeding enable them to pick up a subsistence where they may range over a considerable territory, even where it seems to afford no forms of food for the hungriest animal.

Thus in that part of the city of New York known as "Shanty town," goats may be seen in fairly good condition, although the sole source of food, besides a few stray weeds, appears to be the paste of the paper advertis.e.m.e.nts which they pick from the rocks and fences.

Although goats appear to be characterized by invariable bodies, our sheep are, in physical characteristics, among the most flexible of our domesticated animals. They may by selection readily and rapidly be made to vary as regards the character of their wool, the size and proportion of their muscles, and the quant.i.ty and placing of the fat. In all these features they may be fairly blown to and fro by the wind of favor.

Between the meagre-bodied merino, with its skeleton-like frame and heavily wrinkled skin bearing a vast burden of long wool, and the heavy Hampshire-downs or South-downs, there is really an immense difference in bodily quality; yet these variations represent only a century or two of careful experiment on the part of the breeders. It seems not improbable that in the present state of this developing art it would be possible, in a hundred years, to reverse the conditions of these two varieties.

Sheep and goats, like the other herbivorous species which are the common tenants of our fields and forests, belong to the great cla.s.s of dull-witted mammals in which the intellectual processes appear to be almost altogether limited to ancient and simple emotions, such as are inspired by fear or hunger. They are characterized by little individuality of mind, and although the needs of men have not led to any experiment in developing their wits, as in the case of dogs, there is no reason to believe that they afford much foundation for such essays. The present rapid variations in the physical characteristics of our sheep which are induced by the breeder's skill, make it evident that we are far from having attained the maximum profit from these creatures. The goats also give promise, when selective work is carefully done upon them, of giving much more than they now afford to the uses of mankind; but from neither of these forms is there reason to hope, at least on our present lines of experiment, for any considerable gain in the intellectual qualities.

[Ill.u.s.tration: The Great Caravan Road--Central Asia]

We have already noted the fact that the sheep is especially adapted to serve man in high lat.i.tudes, where he has to provide against the winter's cold. The camel is an even more striking instance in which the value of the creature depends upon climatal peculiarities. It is peculiarly fitted, by its ancestral training and development, for the use of men who dwell in arid countries. In the olden days of the later Tertiary epoch, creatures akin to the camels appear to have been widely distributed, and were probably adapted to considerable variations of environment. Within the time of which we know something by history, these forms have been limited to the arid districts of southwestern Asia and northern Africa. It is not certain that we know the originally wild form of either of the two species, the double-humped or single-humped camels. Wild members of each exist, but they may be the descendants of the domesticated forms. It seems probable that long before the building of the Pyramids the people of the deserts had learned how to profit from the very peculiar qualities of this strangely provided beast, which in several distinct ways is singularly fitted to serve the needs of man in arid lands. The large and well-padded foot of this creature is well adapted for treading a surface unsoftened by vegetation. Its peculiar stomach enables it to store water in such a manner that it can go for days without drink. In the humps upon its back, as in natural pack-saddles, it may harvest a share of the nutriment which it obtains from occasional good pasturages, the store being laid away in the form of fat which may return to the blood when the creature would otherwise starve. So important have these peculiarities been found by men who have domesticated the camel, that on them have rested many of the most interesting features of race development in the history of our kind. In the territories along the eastern and southern sh.o.r.es of the Mediterranean, and in a large part of southern and central Asia, the camel has done service to man which elsewhere has been performed by sheep, cattle, and horses. In those parts of the world the share which these domesticated animals have had in the development of man has been relatively small. The camel has given the strength for burdens, hair for clothing, and often flesh to the needy men of the desert.

[Ill.u.s.tration: The Halt in the Desert at Night--The Story Teller]

Although long a captive, and for ages, perhaps, the most serviceable of all the creatures which man has won from the wilds, the camel is still only partly domesticated, having never acquired even the small measure of affection for his master which we find in the other herbivorous animals which have been won to the service of man. The obedience which he renders is but a dull submission to inevitable toil. The intelligence which he shows is very limited, and, so far as I can judge from the accounts of those who have observed him, there is but little variation in his mental qualities. As a whole, the creature appears to be innately the dullest and least improvable of all our servitors.

The fact is, this animal belongs to an ancient and lowly type of mammals characterized by relatively small brains, and therefore of weak intelligence; but, for its singular serviceableness in drought-ridden countries, it would probably have been hunted off the earth by the early men, as have been many other remnants of the ancient life.

[Ill.u.s.tration: Camels Feeding]

It is somewhat characteristic of the older forms of animals, those which took shape in the earlier Tertiary periods, that they are less variable than those which acquired their characteristics in times nearer our own. It is a fact well known to the students of paleontology, that species and genera which have been long on the earth are apt to become in a way rigid as regards their qualities of body and mind. It is an interesting fact that, although the camel can readily be transplanted to many other parts of the world, where the physiographic conditions are similar to those of the realm where he has served man so well, he has never been thoroughly successful except in the regions where he has been in use for ages. In the desert regions of the Cordilleras of America, in South Africa, and in Australia, various experiments go to show that the creature could be perfectly reconciled to its environment. Many years ago a lot of camels were brought to the valley of the Rio Grande with a view to their utilization in that region, which closely resembles the desert countries about the Mediterranean. These animals were thoroughly successful in meeting the climatal conditions of the region. They proved as strong and as fertile as in their natural realms. Although it is said they survive to the present day, they have never been of any service to the people.

[Ill.u.s.tration: Carrying the Sugar Cane in Harvest--Egypt]

Although, as before noted, the camel has a certain value for other purposes than conveying burdens, these subsidiary uses are so far limited that the creature is not likely to retain a place in the world after his service in caravans is no longer called for. The rapid recivilization of northern Africa, leading as it does to the development of a railway system in that region, promises to displace this creature from his most trodden ways. It seems likely that the other portions of the desert lands in the old world will soon be brought under the same civilizing influences, the nomadic tribes reduced to a stationary habit of life, and the commerce effected in the modern manner. When this change is brought about, this old-time animal, which but for the care of man would have probably long since pa.s.sed away, will be likely, save so far as it may be preserved through motives of scientific interest, to join the great array of vanished species.

[Ill.u.s.tration: Camels along the Sea at Twilight]

It affords a pleasant contrast to turn from the consideration of the camels to a study of the elephants. The difference in the measure of attractiveness of the two forms is very great, and depends upon facts of remarkable interest. Unlike the camel--which, as we have seen, is the last survivor of an ancient lineage, represented by but two species, and these limited to a small part of the world--the elephant, at the time when man appears to have taken shape, seems to have existed on all the continental lands except Australia, and to have been in a state of singular prosperity. As is often the case with other vigorous genera of mammals, the species were adapted to a very great variety of climates, and were fitted to endure tropic heat as well as arctic cold.

The group of elephants is first known to us in the early part of Tertiary time. From its first appearance on our stage it seems to have been successful in a high measure, and this probably by reason of its possession of the remarkable invention of the trunk--a prolonged and marvellously flexible nose which serves in the manner of an arm and hand for gathering food.

When we first find traces of mankind in the records of the rocks, in what appears to be an age just anterior to the Glacial epoch, the elephant had pa.s.sed the experimental stages of its development and was firmly established as the king of beasts. In his adult form he had nothing to fear from any of the lower animals, and by the organization of herds it is probable that even the young were tolerably safe from a.s.sault. Until the early races of men had attained a considerable skill in the use of weapons, the great beasts were probably safe from human attack. We may well believe that primitive savages shunned them as unconquerable. As early, perhaps, as the closing stages of the Glacial epoch in Europe, we find evidences which pretty clearly show that the folk of that land, probably belonging to some race other than our own, had attained a state of the warlike arts in which they could venture to hunt this creature.

The species of elephant which was hunted by the early men of Europe, and perhaps also by those in Asia and America as well, was a greater and, at least in appearance, a more formidable monster than the living species of Asia or Africa. He was on the average taller and probably bulkier than any of his living kindred. The tusks were large and curved in a curious scimitar form. Adding to the might of its aspect was a vast covering of hair, which on the neck appears to have had the form of a mane. This covering must have greatly increased the apparent size of the creature, which no doubt appeared about twice as large as any of our modern elephants which are nearly hairless.

Although the perils of this ancient chase must have been great, the triumphs were equally so, and to a people who lived by hunting, most profitable; a single animal would furnish more food than scores of the lesser beasts such as the reindeer.

It seems probable that the ancient northern elephant continued in existence in North America down to the time when this continent was inhabited by man. It can hardly be doubted that the very ancient human beings, whose remains are preserved to us beneath the lava streams of California, dwelt on the continent along with the mammoth. In excavations which I have made at Big Bone Lick in Kentucky, where a group of saline springs emerges at the bottom of a valley, there were disclosed a very great number of skeletons of this great elephant, commingled with the bones of one or two smaller forms of the related genus, the mastodon. At a slightly higher level was the mult.i.tude of remains belonging to an extinct species of bison which came just before our so-called buffalo, while near the surface of the ground was found the waste of the creatures which were in the field when it was first seen by the white men. A very careful search failed to reveal any trace of man until the uppermost level was attained. The facts, which cannot well be discussed here, have led me to the conclusion that only a few thousand years can have elapsed since the mammoth and the mastodon plentifully abounded in North America; but I am forced to doubt whether our savages were here in time to make acquaintance with these animals.

It is not certain that the extermination of the great northern elephant or mammoth even in the Old World came about through the action of man. It is possible that the death was due to more natural causes, such as the change of climate which attended the decline of the Glacial period, or to the attacks of some insect enemy like the tsetze fly of South Africa, which occasionally brings destruction to cattle in that part of the world. On the whole, however, it seems most probable that the extermination of this n.o.ble beast is to be accounted among the brutal triumphs of mankind, perhaps as the first of the long tale of destructions which he has inflicted upon his fellow-creatures. However this may be, it is clear that at the dawn of civilization the species of the genus elephas had become limited to that part of the African continent which lies south of the Sahara, and to the portion of Asia east of the Persian Gulf and south of China. The remnant consisted of two species: the African form, on the average the larger of the two, a fierce and scarcely domesticable creature; and the Asiatic, a milder-natured species which alone has been to any extent brought into the service of man.

It is not certain when or where elephants were first reduced to domestication. In the dawn of history we find them used to enhance the state of princes and for the purposes of war. It seems possible that in this early day the African as well as the Asiatic species was tamed, at least to the point where they could be made to serve in battle. We can hardly believe that all these animals which were at the command of Hannibal and the other generals of North Africa, came from the Asiatic realm. The fact that in modern times the species which dwells south of the Sahara has not been turned to the uses of man, may be accounted for by the lowly estate of the native people in that part of the world, and the lack of need for such creatures in the economic conditions of the Aryan folk who have settled along the sh.o.r.es and in the southern part of that continent.

The relations of man to the elephant are more peculiar than those which he has formed with any other domesticated animal. Although the creature will breed in captivity, its reproduction in that state is exceptional, and it is many years before the offspring are fit for any service. It is indeed about thirty years before the creature is sufficiently adult to attain a good measure of strength and endurance. It has therefore been the habit of the people who avail themselves of this admirable beast to use the captures which they make in the wilderness. It is a most interesting and exceptional fact that these captive elephants, though bred in perfect freedom and provided with none of those inherited instincts so essentially a part of the value of our other domesticated quadrupeds, become helpful to man and attached to him in a way which is characteristic of none other of our ancient companions except the dog. It is safe to say that the Asiatic elephant is the most innately domesticable, and the best fitted by nature for companionship with man, of all our great quadrupeds. The qualities of mind which in our other domesticated quadrupeds have been slowly developed by thousands of years of selection and intercourse with our kind, are in this creature a part of its wild estate.

It appears from trustworthy anecdotes that the Asiatic elephants in a few months of captivity acquire the rules of conduct which it is necessary to impose upon them. The speediness of this intellectual subjugation may be judged from the fact that, after a short term of domestication, they will take a willing and intelligent part in capturing their kindred of the wilderness, showing in this work little or no disposition to rejoin the wild herds. In the case of no other animal do we find anything like such an immediate adhesion to the ways of civilization. We have to account for this eminent peculiarity of the elephant on the supposition, which appears to be thoroughly justified, that the creature has, even in its wild state, a type of intelligence and instincts more nearly like those of men than is the case with any other wild mammal, an affinity with human quality which is, perhaps, only approached by certain species of birds. It appears from the observations of naturalists that the family or tribe of wild elephants is a distinct and highly sympathetic community. The grade and value of the friendly feeling which prevails among them may be judged by the fact that, when one of the males becomes lost or is driven away from its a.s.sociates, it does not seem to be able to join any other tribe, but becomes a "rogue," or solitary individual, and in this state develops a morose and furious temper.

There are many well-attested stories which serve to show that wild elephants have a kind of intelligence which indicates a certain constructive capacity. Of these, perhaps the best are the instances in which the creatures have been caught in pitfalls, made by digging a hole in the paths of the wilderness which they are accustomed to follow, the surface being covered with a frail platform so arranged as to conceal the excavation. When one of a tribe is caught in the trap, the others, if time allows before the hunters come to the ground, will in an ingenious way release him. I doubt if the most practicable manner of effecting this will occur at once to the reader. The easiest plan may seem to drag the captive from the pit by sheer strength, but as the hole is deep and has vertical sides, the elephants contrive a better way. They bring bits of timber, which they throw into the pitfall, the captive treads them down until he is elevated to a position whence he can escape from his prison.

The intelligence of the wild elephant is probably in good part to be accounted for by the fact that the creature possesses in its trunk an instrument which is admirably contrived to execute the behests of an intelligent will. It is easy for us to see how, in the case of man, the hands have served to develop the intelligence by providing him with means whereby he could do a great variety of things which demanded thought and afforded education. The elephant is the only large mammal which has ever acquired a serviceable addition to the body such as the trunk affords. In their ordinary life the trunk does almost as varied work as the human arm. With it they can express emotions in a remarkable way; they caress their young, gather their food by a great variety of movements, or defend themselves from a.s.sailants. To the naturalist who has come to perceive the close relations between bodily structure and mental endowments, it is not surprising to find that these creatures have attained a quality of mind which is found nowhere else among the mammals except in man and in some of his kindred, the apes.

The most peculiar mental quality of the elephant, a feature which separates him even from the dog, is the rational way in which he will do certain kinds of mechanical work. He appears to have an immediate sense as to the effects of his actions, which we find elsewhere only among human beings. From a great body of well-attested observations, showing what may be called the logical quality of the mind of these creatures, I may be allowed to select a few stories which have a singular denotative value. An acquaintance of mine, a British officer who had served long in India, told me that in taking artillery over very difficult roads, certain of the abler elephants could be trusted to walk behind each piece, where they would in a fashion control its movements, steadying or lifting it as the occasion demanded without any directions from the driver.

[Ill.u.s.tration: An Indian Elephant]

Elephants can be trained to pile up sticks of timber, such as railway ties, placing the layers alternately in opposite directions, as is the custom in such work. There is an excellent and well-attested story of an elephant who, without a driver, was bearing a stick of timber through a narrow wood path. Meeting a man on horseback, and perceiving that the way was not wide enough for both himself and the oncomer, the sagacious animal deliberately backed his huge body into the chaparral so as to clear the way, and then trumpeted as if to signal the horseman that the path was free.

The emotions as well as the intelligence of elephants are singularly like those of human kind. It is said by those who know them well that if when in their stubborn fits they are brutally overborne, they are apt to die of what seems to be pure chagrin. Their states of grief, despair, and rage much resemble those which are exhibited by violent children or men unaccustomed to control. Their affections and animosities have also a curious human cast. They readily form attachments which appear to be quite as enduring as those exhibited by dogs, and their memory of injuries remains quick for years after they have received the harm. Well-verified anecdotes showing the likeness of these emotional qualities to our own exist in such numbers that it would be easy to fill a volume with them. They are, however, not necessary to show the likeness of the creature to ourselves. This is sufficiently exhibited by their daily behavior under domestication. In noting this we should remember that the male elephant is the only large mammal the males of which it has proved safe to use in the ordinary work of life. Even our bulls and stallions, though they belong to species which have been domesticated for thousands of years, are so violent and untrustworthy as to be of little value except for breeding purposes. Bulls, even of the tamer breeds, are a constant menace to the lives of their masters; yet an adult male elephant recently made captive may, except when seriously diseased, be trusted to obey the mere signals of the driver, who has no such control over him as the bit affords in the case of horses. The creature has the strength to overcome all control save that of a moral nature. To this he submits in a way which is only equalled by our well-bred dogs.

As yet the utility of the elephant to man has, measured by his qualities, been but small. The creature has a marvellous strength, great intelligence, and remarkable docility. In proportion to the power which he can apply to a task, he is not an expensive animal to maintain. He can endure a considerable range of climate, and enjoys a tolerable immunity from disease. The reason for the relatively inconsiderable use of these creatures is probably to be found in the fact that they are not adapted for ordinary draught purposes, nor are they well suited to the needs of the caravan, for which the camel or the pack-mule is much better fitted. In ancient warfare, before the invention of gunpowder, elephants carrying archers or javelin-men upon their backs were greatly valued for the effect of their charge against an enemy and for the fright with which they inspired horses. Against the unsteady ranks of Oriental armies they were often most efficient in breaking a line of battle. Even the Roman troops, when they first encountered them and before they knew how to meet their charges, found them very formidable. It was soon learned that if their onset was stoutly resisted, they were likely to become unmanageable in the uproar of the fight, and to do as much damage to friends as to foes.

It is only in certain peculiar tasks that, in modern days, the elephants have any economic value, and in the most of this work their strength is likely to be replaced by various engines.

The two existing species of elephants are, as before remarked, the survivors of a long lineage, represented in the geological record by the remains of many extinct forms. Some of these lost species were far smaller than those of to-day; one at least was no larger than our heavier horses. If by the breeder's art the existing varieties could be caused so to change as to give us once again this relatively diminutive form, the creature would be sure to find a place of importance in our ordinary arts. The trouble is that the very long life of this animal is naturally a.s.sociated with a slow growth. It requires indeed almost the lifetime of a generation to bring the individual to an adult age. It is therefore not surprising that, as the wild forms can readily be won to domestication, these creatures have not been the subject of any of those interesting processes of selection which have so far affected for the better the characteristics of nearly all the other domesticated animals.

In every other regard than those mentioned above, the elephant appears to be an excellent subject for improvement by choice in breeding. The individuals vary much as regards their physical and mental qualities.

Probably no other wild mammal exhibits such differences in the mental features as does this highly intellectual creature. The physical individuality does not seem to be as striking as the mental, but even here we note a range, at least as regards size, which is unusual in the wild forms bred under similar conditions. The general elasticity of the group is shown by the considerable differences which may be traced in the herds which occupy different parts of the field over which the species range. As yet these local peculiarities have not been carefully studied; but from an examination of the tusks in the ivory warehouse at the docks in London, I have found that those shipped from particular ports in Africa and Asia differed both in form and texture, so that the experts were able to tell from which district they came. The evidence, in a word, appears to show that the creature tends to vary; and it is a safe presumption that the forms would prove as responsive to the breeder's art as those of our horses, cattle, sheep, or dogs.

As a whole, the elephant has been almost as little a.s.sociated with the life of our own race as the camel. Neither of these creatures has ever played any considerable part in European affairs. From the disappearance of the last of the mammoths in the closing stages of the Glacial time until the invasions of Italy by Pyrrhus and by Hannibal, elephants were practically unknown in Western Europe. They have never been used in peaceful occupations on that continent, and have had only a trifling place in its military arts. It was probably due to this separation of our eminently experimental race from the realm of the elephants that no efforts have been made systematically to breed them in captivity, and thus to win varieties in which the form might become better adapted to economic needs, and the remarkable mental powers of the creature be brought to their utmost development. As yet the only Europeans who have had much to do with elephants are the British, who in their civil and military service in India have been thrown in contact with these animals. Generally, however, these people have been only temporarily domiciled in Asia, and probably on this account have not become interested in the problems which this n.o.ble beast presents to all those who appreciate the animal world. We lack, indeed, the observations which might have been made with admirable effect by British observers in India during the two centuries in which that people has had to do with the lands in which elephants abound.

The elephant of Africa is still a tolerably abundant animal. Its numbers, though doubtless diminished by more than one-half within this century, are probably to be counted by the hundred thousand.

Nevertheless, in less than a hundred years the field which they occupied has been greatly reduced; and between the ivory hunter and the sportsman of our brutal race armed with guns of ever-increasing deadliness, it will certainly not require another century of free shooting to annihilate the African species. In view of the present condition of the life of these n.o.ble beasts, it seems in a high measure desirable that a thorough-going effort should be made to extend the domestication to the point where the form will not only be won from the wilds, but will be a permanent element in our civilization, in the manner of our common flocks and herds. It will be an enduring shame if, by neglect of our opportunities, the utmost is not done to attain this end. It appears fit that this task should be undertaken by the British Government, which in modern days has displayed a skill and forethought in the administration of its Indian provinces unexampled in the history of colonies. Owing to the slow breeding-rate of the elephant, it may require more than a century for experiments to attain any definite result, so that the task is clearly beyond the limits of individual endeavor.

Among the humbler helpers of man, the pig holds an important place. He has had no small share in the betterment of the estate of his masters.

One of the large questions which beset men in their unconscious endeavors to lay the foundations of civilization was that of food-supply. No sooner does a population become sedentary than the wildernesses about its dwelling-place are rapidly cleared of the large game, so that the chase affords but little save amus.e.m.e.nt. Therefore a provision in the way of meat has to be obtained from domesticated animals. The flocks and herds supply this need, though in a costly way.

Sheep have a value for their wool; horned cattle develop slowly, and are, moreover valuable, the oxen for their strength and the cows for their milk. Horses are too valuable to be used for food, save in times of exceeding stress; and none but the lowest savages are willing to send their faithful dogs to the pot. From the beginning of his experience with man the pig has been found the cheapest and most serviceable domesticated animal as a source of food-supply.

We can trace the origin of our domesticated pigs more clearly than in the case of the most of the other subjugated animals. The creature is evidently descended from the wild boar of Europe and Asia; and though long under domestication and greatly varied from its primitive stock, it readily reverts to something like its original form when allowed to betake itself once more to the wilds. The domestication of the species appears to have been accomplished at several different points in Asia and Europe. The forms which are found in eastern Asia differ from those which are kept in the western portion of the great continent, and may have their blood commingled with that of another species which is native in that part of the world.

Among our domesticated animals the pig is exceptional in the fact that it has been bred for its flesh alone; for although the hide is valuable and the hair serves certain purposes, as in the manufacture of brushes, these uses are only incidental and modern. They have not affected the plan of the breeder, whose aim has been to produce the largest weight of flesh in the shortest time, and with the least expenditure of food. In this peculiar task the success has been remarkable, the creature having been made to vary from its primitive condition in an extraordinary manner. In its wild state the species develops slowly, requiring, perhaps, three or four years to attain its maximum size. It never becomes very fat, but remains an agile, swift-footed, and fierce tenant of the wilds. Under the conditions of subjugation the pig has been brought to a state in which its qualities of mind and body have undergone a very great change. In the more developed breeds, even the males, when kept about the barnyard, are quiet-natured and not at all dangerous. The creatures have become slow-moving; they attain their full development in about half the time required for the growth of their wild kindred, and when adult they may outweigh them in the ratio of four to one.

The effect arising from the food-supply which our pigs afford is well seen in the use which is made of their flesh in all the ruder work of men, at least in the case of those of our race. Our soldiers and sailors are to a great extent fed on the flesh of these creatures, which lends itself readily to preservation by the use of salt. So rapidly can these animals be bred, owing to the number of young which they produce in a litter and the swiftness of their growth, that sudden demands for an increase in the supply, such as occurred at the outbreak of our civil war, can quickly be met. If the need should arise, the quant.i.ty of pork produced in this country could readily be doubled within eighteen months. This is the case with no other source of flesh-supply, and this fact gives the pig a peculiar importance.

Owing to the remarkably complete domestication of this animal, and also to the fact that it is omnivorous, the creature has ever been a favorite with the cotter cla.s.s. Those folk, who can afford neither sheep nor horned cattle, can often provide the food for pigs, and thus, in turn, be much better fed than they would otherwise be.

It is only within two centuries that our pigs have attained to anything like the domestication in which we commonly find them. Of old they were allowed to range the forests, much as they do in certain parts of our Southern States at the present day. In some parts of Europe, particularly in the southern portion of the continent, this method of rearing and feeding is still common. It was and is advantageous, for the reason that the creature, by its remarkably keen sense of smelling and its singular capacity for overturning the ground, is able to provide itself with abundant food in the way of grubs and roots which are not at the disposition of any other animal.

It was only as the public forests disappeared that pigs came to receive any considerable part of their provender from the products of tilled fields. In this stage of our agriculture, when all the land was possessed, the life of the pig was necessarily more restricted, and he became the denizen of a pen. In the earlier state there was no cost for his keeping; in the latter, except so far as he could be fed from the waste of a household, he is an expensive animal.

It is with this last state of the pig, when he became the most housed of our domesticated animals, that the work of the breeder really began. The aim of those who have developed the pig has been, as we have said, to obtain the most rapid growth along with the greatest weight of fat, and to accomplish the results with the least expenditure in the way of food. Although the animal has been subjected to selective experiments, looking to these ends, for not more than a century, or say about forty generations of the species, the amount of variation which has been attained is singularly great, the form and habits having been changed more rapidly, and in a larger measure, than in the case of any other of our domesticated animals. It may fairly be said that this creature is more obedient to the will of the practical selectionist than any other with which we have experimented.

It is commonly a.s.sumed that our pigs are among the least intelligent of the creatures which man has turned to his use. This impression is due to the fact that the conditions in which these animals are kept insure their degradation by cutting them off from all the natural mental training which wild animals, as well as the other tenants of the fields, receive. In the state of nature or in the condition of domestication which existed before pigs became captives in their pens, they were among the most alert and sagacious animals with which man has come in contact. Their wits were quick and their sympathies with their kind remarkably strong. Trainers have found these creatures more apt in receiving instruction than any other of our mammals, and the things which they can be made to do appear to indicate a native intelligence nearer to that of man than is found in any other species below the level of the apes.

As there is little in the books of anecdotes of animals concerning pigs, I venture to give an account of a learned individual of this species whose performances I had an opportunity of observing in much detail. The creature, an ordinary specimen about three years old, had been trained by a peasant in the mountain district of Virginia who made his living by instructing animals for show purposes. He stated that in selecting pigs for education it was his practice to choose those characterized by a considerable width between the eyes and whose skulls projected in this part of their periphery to a more than usual degree. He said that from many experiments he was satisfied that there was a very great difference in the capacity of the animals to receive training, and that the above-mentioned indices afforded him sufficient guidance in his choice.

In the exhibition about to be described there were but three persons present, myself, another spectator, and the showman. A score of cards were placed upon the ground, each bearing a numeral or the name of some distinguished person. These cards were in perfect disorder. I was allowed, indeed, repeatedly to change their position and to mix them up as I pleased. The pig was then told to pick out the name of Abraham Lincoln and bring it to his master. This he readily did. He was asked in what year Lincoln was a.s.sa.s.sinated. He slowly but without correction brought one by one the appropriate numerals and put them on the ground in due order. Half a dozen other questions concerning names and dates were answered in a similar way. Each success was rewarded with a grain of corn, and for his failures the creature received a reasonable drubbing. It was evident that the animal had to consider in making his choice of the cards. At times he was evidently much puzzled and would indicate his perplexity by squealing.

It seemed clear that the master of this learned pig did not guide the movements of the animal by other indications than words. The questions, in some cases, had to be reiterated in a loud voice in order to insure attention. Several times during the performance the pig rebelled, broke from the tent, and was with difficulty recaptured. The creature disliked this task in the manner of a lazy school-boy, and at the end of an hour of exercises seemed utterly overcome by his labor. He ran into the box where he was ordinarily confined, and when dragged forth, neither rewards nor punishments would quicken him to further work.
