t, 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 assumed 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 assassinated. 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.

The above-described exhibition made it plain to me that the pig can be taught to understand a certain amount of human speech and to associate memories with phrases substantially as we do ourselves. It is perfectly clear that the performance which I witnessed was not a mere routine action, for I had a number of questions asked over again so as to make it sure that the creature acted with reference to each separate inquiry. The behavior of the animal during the performance seemed clearly to indicate mental effort and not mere automatic memory. His attitude when trying to determine which of two cards to take distinctly showed that he was intently viewing the figures and endeavoring to come to a decision. I am aware it has been suggested that learned pigs discriminate between the cards by peculiarities of odor which have been given to these bits of paper. I sought carefully to find if such was the case, and though I have a very keen sense of smell I found nothing which led me to suspect that this device was used. Even if such were the case, the rationality of the animal's action would be none the less clear. The showman assured me that he never used any such means in training pigs. He seemed, indeed, to treat the suggestion with contempt.

Although experiments in the training of pigs show that they have rather remarkable intellectual capacities, the most human feature in their mental organization is found in the keen sympathy which they exhibit with the sufferings of their own kind and the willingness with which they encounter danger in protecting their comrades. It usually requires close observation for the naturalist to determine the existence of this motive among the other wild or domesticated mammals. In fact, the traces of it are very slight indeed, and are generally to be attributed to the care of parents for offspring or of the males for their harem--a disposition which, though akin to the defence of the kind, is nevertheless of a special and peculiar nature. Even among our domestic dogs, whose sympathies have been developed in a remarkable degree and who will sacrifice their lives to defend or rescue the human beings with whom they are familiar, there appears to be but little disposition to support members of their species who may be assailed. With pigs, however, as is well known to all those who have observed their habits, the characteristic cry of distress of their fellows proves very exciting and stimulates all the adults, both male and female, who hear it to hasten in defence of their kinsmen. It is a noteworthy fact that while most other animals when in danger utter no distinct or continuous cry, the pig gives voice in a vociferous and insistent manner, as if he had a right to expect the sympathy and help of his species. The cry goes with the custom of defence which in this species has attained a better foundation in the sympathetic motives than in any other mammal below the level of man.

It is perhaps due to their relatively high intellectual organization that the excessively domesticated pigs are liable to suffer from attacks of mania. This is most commonly exhibited by the sows, which at times will destroy their young shortly after they are born. The sight of their progeny seems to infuriate them in a curious manner. One sow which I owned killed three successive litters; another fine animal of the Berkshire breed, a very amiable, indeed affectionate, creature, was carefully watched at the time she first bore young, precautions being taken to prevent her from harming them; she would willingly allow them to suckle, provided she did not see them, but the moment she laid her eyes upon them she was seized with the strange fury.

Although this singular perversion of the natural instincts of maternity sometimes occurs among the pigs which are allowed to roam together in herds, it seems to be far more common in those conditions where the animals are confined in pens without contact with their kind, and where they have no chance to recognize the young as members of their species or to acquire that interest in them which they would gain in the society of the herd. It is also clear that this maniacal habit is inherited; according to my observation it is common among the Berkshire, and relatively rare in other less specialized varieties.

The intelligence of the pig is also shown in the readiness with which the creature changes its habits to meet varied environments. Thus the pigs which range the woods in the western and southern parts of the United States have learned to catch the crawfish which abounds in the shallow streams in those parts of this country. They will wade up a brook, turning over the stones and driftwood as they go, catching with a quick movement the crustaceans which they have thus dislodged from their cover. Along the shores of the Bay of Fundy, the pigs, accustomed to follow the tide out, picking the chance food which is thus exposed to them, have learned carefully to avoid the risk of being caught by the returning waters. With the first splash of the turning tide they hasten inshore until they have attained safe ground.

One of the best evidences of the mental state of these animals is found in their actions when assailed by dogs or other beasts of prey. Pigs, though wary and sensible of danger, seem exempt from the extreme fear which leads to panic, and fight, even before being brought to bay by long chasing, in a discreet and valiant manner. Where a number of them are attacked by dogs or other enemies, they will form a circle with their heads out, each supporting the other in such a manner that the ring cannot readily be broken. Their thick-skinned forequarters and stout tusks provide them with excellent instruments with which to resist an assault.

The sagacity of the pigs is probably, in part at least, to be attributed to the fact that in their native state they are communal animals, all the species of their family being accustomed to live gregariously, so that for ages they have had the training which every social organization, however simple, affords. They are, moreover, omnivorous feeders, accustomed to subsist on a great variety of food--a habit which seems in all cases to promote the development of the intelligence in animals.

Although the pigs by their nature afforded the best opportunity for developing an intellectual animal which has come to us through our domesticated creatures, no effort whatever has been made by selection to develop the latent mental capacities of this species. It is perhaps the only form of those which man has subjugated which by his treatment he tends to degrade. In the time to come, when men will be held to a better accountability for the treatment of their captives, the condition of these animals will afford a fair field for the reformer's care.

The geologist who is acquainted with the mammalian life of the Middle Tertiary period readily notes the fact that the variety in genera and species appears to be much greater than it is at the present time. A great number of forms, differing somewhat widely from those now in existence, then abounded in the Americas and the Old World. It may at first sight seem unfortunate that man did not have the chance to essay his domesticative arts on that older and apparently richer life. A closer examination, however, leads us to see that the species of that time, though more numerous than those of the present, were on the whole less fitted for our use than the fewer but more completely differentiated kinds with which we have had to deal. The multitude of kinds which we find in the Mesozoic period indicates that the life was in a state more experimental than that to which it has attained. A host of forms on their way towards the specialization which has now been attained have been removed from the sphere, in the manner of a scaffolding from a completed structure. That which has been left remains because it has successfully accomplished the task of reconciliation with environment, or, in simpler phrase, because it has learned to do things which were useful and profitable in a more perfect manner.

As an illustration of the fact that the animals of to-day are better fitted to be the help-meets of man than were their ancestors of an earlier time, we may note the state of the horse at the time when that genus was undergoing its development in the region about the upper waters of the Missouri. As may be imagined, the long and difficult passage from the five-toed to the single-toed form was slowly accomplished, and to its doing went a great many temporary forms, which served, we may say, as stepping-stones for the ongoing. So far as we can judge, these intermediate forms were small, rather frail creatures, which probably could not have been made to serve any purpose useful to man. It was not until the mechanical system of the large single toe with the wonderfully developed nail, which makes up the foot and hoof of the horse, had been attained, that the creature becomes fit for the wonderful work we have persuaded him to do in our civilization.

A comparison of the skulls of the Tertiary mammals and those of our own day indicates that in certain of the important series, and presumably in them all, the brain has increased in size from the earlier to the later times. This increase in brain capacity has doubtless been attended by a decided gain in the measure of intelligence, a gain which has doubtless served to make the modern representatives of the series fitter for man's use than their ancestors were. For, while the number of our very useful domesticated forms may seem at first sight to be dull of wit, none of them are really low in the intellectual scale as we apply it to the brute; in fact, a considerable measure of intelligence is absolutely required as a condition for true subjugation. This is seen by the fact that nothing like a real adoption into our social system has ever been accomplished except with a few of the higher orders of mammals and birds, species which have an intellectual capacity that we recognize as akin to our own. Thus, so far as we can see, man's appearance on this stage was, so far as it relates to the possibility of companionship with the lower life, exceedingly well timed. He came at a period when the life was ready to give him and to receive from him a large measure of help. If his advent had been much earlier, he might have had less trouble in his contests with the larger carnivora; but if there had been a lack of beasts to obey his will, it is doubtful whether he could himself have won his way above that primitive life.

DOMESTICATED BIRDS

Domestication of Animals mainly accomplished by the Aryan Race; Small Amount of Such Work by American Indians.--Barnyard Fowl: Mental Qualities; Habits of Combat.--Peacocks: their Limited Domestication.--Turkeys: their Origin; tending to revert to the Savage State.--Water Fowl: Limited Number of Species domesticated; Intellectual Qualities of this Group.--The Pigeon: Origin and History of Group; Marvels of Breeding.--Song Birds.--Hawks and Hawking.--Sympathetic Motive of Birds: their AEsthetic Sense; their Capacity for Enjoyment.

It is an interesting fact that about all the work of domestication which has been done by man has been accomplished by the peoples of Asia and mainly by the Aryan race. The American Indians tamed the llama and alpaca and a few species of native plants; even where their habits were prevailingly sedentary they domesticated no birds. It was left for Europeans to make use of the wild turkey. Our primitive people had the same chance to tame ducks and geese as the folk of the Old World. They appear, however, to have lacked all capacity for such endeavors. The same lack of disposition to capture and tame wild creatures is noticeable among the characteristic peoples of Africa; all of which serves to show that the domesticating art, at least as applied to animals, is peculiar to the higher-grade folk of the Old World.

Of all the birds which have been domesticated, our common barnyard fowl has been by far the most useful to man. It has become in a way interwoven with his life to a degree found only in a few of our barnyard animals. Next after the pigeons and the pigs it has been most deeply impressed by the breeder's art. The wild species whence it sprang is a small creature, laying but few eggs and with but a slight tendency to accumulate fat. From this parent stock varieties have been bred which attain in some cases to eight or ten times the weight of the ancient form. They have, moreover, lost the fierce combative spirit which characterizes their ancestors and which by selection has been preserved and intensified in our breeds of game-cocks.

A part of the fitness of this creature to cast in its lot with man arises from the fact that they have very sympathetic natures. This is shown by the way in which the cocks will fight for their hens, even against their dreaded enemies, the hawks; and by the manner in which the mother, overcoming her natural fears, will do battle for her brood. It is shown also in the curious mingling of gallantry and kindliness with which the cock will call a hen to give her some choice bit of food which he has captured. As he grows older and becomes Philistinish, we may note that, after the manner of unfeathered bipeds, he is often disposed to indulge his selfishness, and summons his flock only to see him devour the morsel. Even in old age, however, the males of the varieties which are nearest the parent stock maintain their helpful motives and will struggle with infirmity to beat off a bird of prey.

The sympathetic and affectionate quality of our barnyard fowl is perhaps best indicated by the singular variety and denotative value of their various calls and cries. Those who know these birds well will find no difficulty in recognizing about a score of diverse sounds, each of which indicates a particular turn of their mind. Almost all of these different notes have slight variations of expression which fit particular situations. Thus the crow of these birds, which may seem to the unobservant a very unvaried sound, discloses to those who have lovingly studied them at least half a dozen distinct modifications. In the fledgling male who just begins to feel the spirit of his kind, and who goes through his performance in the adolescent way, it is a cheap and often pitiful call. From the open roost in the trees, where the birds are gradually aroused by the slow-coming day, we can often hear the note of the half-awakened cock, as full of the sense of slumber as the speech of a sleeping man. As the creature gradually awakens, his cry becomes more resonant until it has the true morning ring. Brave as is this note of the full day, it is not to be compared with the crowing of a game-cock, the most splendid braggart sound of all the animal world.

The really sympathetic notes of our fowls are uttered in their ordinary intercourse. Here the gradations of sounds have a range and fineness which, it seems to me, we can observe in no other creature below the level of man. Attention, astonishment, fear, commonplace distress, exultation, and agony are all set forth with cries which we, in a way, recognize as appropriate. Although some of these sounds relate to the larger experiences of the creatures, the most instructive of them are uttered in their ordinary intercourse, where they clearly maintain a kind of consensus in the flock by unending small bits of emotional speech, the notes being shaded in a wonderful way. These fine variations of utterance can sometimes be observed to be related to slight differences of situation. Thus the cackle of a hen when she leaves her nest after laying an egg is quite different from that which is made by the same hen when, during the period of incubation, she quits her eggs in search of food and water.

It is not unlikely that the eminent domesticability of our common fowls is in a way associated with the singular variety of their notes. This variety indicates that the creatures are in constant and effective communication with one another; in a word, they are very sympathetic. With this intellectual helpfulness naturally goes the love of the domicile and a disposition to submit to control.

So nice and well understood are the differences between the sounds which these birds give forth, and so well are their notes appreciated by their companions, that the creatures may well be said to have a language. Though it probably conveys only emotions and not distinct thoughts, it still must be regarded as a certain kind of speech. The modes of expression indicate that in this creature, as in the other feathered forms, the intellectual life consists largely in the movements inspired by the emotions. On the rational side our fowls seem weaker than many other less interesting species. In their nesting and other habits there are no evidences of constructive ingenuity; and in all my observations on them I have never seen any evidence which showed either considerable powers of memory or a capacity to act in any complicated way with reference to an end. It is evident, however, that they make a very good classification of the world about them. They have, for the limited field over which they roam, a keen topographic sense; they never are lost, and this in connection with their sympathetic homing instinct prevents them from wandering from their accustomed places to take up again with a wilderness life.

In their adhesion to domestication our common fowls differ in a remarkable way from all other of our captive animals except the dog, and these birds are even more ineradicably attached to man than their older companion. While the dog will sometimes become half wild, or, as we may phrase it, undomiciled, fowls seem incapable of maintaining themselves apart from human care. In much ranging of the wilderness I have never found one of these creatures more than a thousand feet away from a human habitation. When we consider how common must be the chances of their going astray, and how easy it is in many parts of the country, as in our Southern States, for them to obtain in the wilderness food throughout the year, the fact that they never go wild is indeed remarkable. It can only be explained by the great development of the homing instinct which man has brought about in their sympathetic souls.

Although our unnatural process of breeding has done much to degrade the original beauty of the cocks and hens, destroying the delicate coloration of the feathers as well as the admirable blending and contrasts of their pristine hues, it seems likely that the effect on the physical and mental development as a whole has not been unfavorable. Though less courageous, they are stronger creatures than in their wild state; they are clearly more fecund; they are gentler natured; and, so far as I have been able to compare the high-bred with the primitive forms, their range of expression through the voice has been much increased, a feature which may be noted in other domesticated species of birds, as, for instance, in the canaries. The most remarkable alteration which has been brought about in the minds of these creatures consists in the very great diminution in the combative motive of the males. In the wild forms, as well as in the kindred variety of the game-cock, this impulse to battle attains a truly phenomenal development, the like of which is probably not to be found in any other creature. The male birds begin their warfare before they are more than half grown, and in their adult state will attack anything which they can conceive to be an enemy. They will, with slight provocation, assail any of the other domesticated species of birds, and even the lesser mammals, such as the dogs and cats. They will fight their own image in a looking-glass. I have had game-cocks attack my hand when it was held near the ground and given an up-and-down movement in imitation of their antagonist's head.

I once reared a game-cock by hand, keeping him secluded from his kind until he was adult. I then placed him in a large collection of barnyard fowl where there were half a dozen mongrel cocks, a drake of the muscovy variety, several ganders, and two turkey-gobblers. Immediately and in rapid succession he settled his accounts with the males of his own kind. He shortly overcame the drake and the ganders. He then devoted what was left of his forces to battles with the turkeys. Here he found himself in great difficulty, for the reason that these great birds would seize him by the head and lift his body off the ground. However, he soon learned an ingenious trick which protected him from this danger. When gathering breath in the intervals between his assaults, he would hover himself between his antagonist's legs, keeping step with the awkward creature in its efforts to get away from him. In a few days he wore out these doughty foemen and remained the battered master of the field.

Although the indomitable valor of the game-cock may be in some measure due to the selection which the breeder has applied to the variety, there can be no question that it is essentially natural to the species and is the result of an age-long habit which in the native wilds of the creature did much to insure its safety. The antiquity of the state of mind may be judged by the perfection to which the spurs have attained and the remarkably skilful and definite way in which the creatures use them. The spur, which has arisen from the development of the scales and underlying bone of the bird's leg, is a singularly perfect structure, the finish of which cannot be judged in the degraded form in which it is found in our ordinary barnyard species. Although in its construction this weapon is admirably devised, it is placed in a position where only a remarkably well-addressed movement can give effect to its blow. Those who have watched game-cocks in combat have had a chance to see the vaults by which the creature, partly turning in the air, is able to throw the spur in such a manner that it shares the impulse of the body when it strikes the antagonist. This peculiar craft has been in good part lost among our common varieties. Their spiritless contests differ as much from those of the game-birds as do the fist fights of untrained men from the contests of skilled pugilists.

Although to persons unaccustomed to the spectacle the combats between game-birds may seem disgusting, almost every one must admire the valor, grace, and address which such scenes exhibit. Except where the brutal custom of putting steel points on the spurs prevails, the birds rarely receive fatal wounds. The defeated cock is soon brought to confess his inferiority and takes himself away. At no other time in the life of these birds does their organic beauty appear to such advantage as when they are struggling with each other. Then alone do we perceive the singular efficiency of their bodies and the quick as well as appropriate action of their instincts. They set themselves against each other in attitudes as well chosen and as peculiar as those of a well-trained fencer. Before the assault they often go through a singular performance, which consists in picking up bits of twigs or pebbles. These they cast into the air, an unmeaning movement which may be compared to the like meaningless though similarly graceful salute with which swordsmen preface their contests. Then, with their legs flexed so that they may be ready for the spring, and with the rather stiff feathers about the neck erected so as to serve as a shield, they creep toward each other until they are separated by the distance appropriate for the spring. When fairly placed for battle they begin a system of fence which is intended to provoke the enemy to an untimely assault. The art of the game appears to consist in persuading the adversary to venture an attack where his force will be spent in the air, so that a blow can be given him before he has time to recover position. The issue depends much on the endurance of the birds. Their movements require so much energy that one of them is apt to become exhausted before the other is quite spent. In rare cases, only one of which has been seen by me, a weary bird will feign death for a minute or so and thus obtain new strength with which to renew the combat, profiting also by the confusion which he will bring upon his adversary by his sudden revival.

Although the combatant motive which we find in the males among our barnyard fowls has doubtless been developed through their combats with each other, the valiant spirit which has come from it often leads the creatures to attack the enemies of their flock. I have seen a nimble game-cock strike a hawk which was pouncing to its prey, delivering the blow some feet above the surface of the ground, and this so effectively that the marauder was driven away in a sorely hurt condition. I have seen males of the game variety attack a number of other larger animals which in any way threatened their charges.

Although our barnyard fowl are almost the only ground birds which have ever been brought to a state of perfect domestication, there are several other species of the same group which have been taught in a measure to adhere to man. Of these perhaps the longest in domestication is the peafowl. This creature, though it has edible, indeed we may say savory flesh, has retained its small place in civilization solely on account of its extraordinary beauty. For its size it is doubtless the most beautiful of animals, its plumage, especially the magnificent display of the tail, exceeding that of any other natural object. There are other birds of small size which vie with the peacock in the details of ornamentation. Those jewels among the feathered tribes, the humming-birds, have a more delicate beauty. The birds-of-paradise and the lyre-birds have a grace in the attitudes of particular feathers which is unequalled; but for splendor none of them approach the peacock in his best estate.

The peacock is a native of Southern Asia, a realm in fact in which the species of the group attain an uncommonly rich development. The creature appears to have been domesticated some thousands of years ago, but has undergone no considerable changes in its experience with man. It has in truth not been completely tamed. It does not willingly remain near the dwellings of man, but prefers to abide apart, only resorting to the home when in need of food. It is very intolerant of the other barnyard creatures, and often becomes possessed of a kind of mania for slaying their young, not for food but from pure spirit of mischief.

Intellectually speaking, the peacocks are much below the cocks and hens; although they flock together, their sympathies do not seem quick; their cries and calls do not number a fifth part of those which we hear from our chickens, and their notes are prevailingly very discordant. Their cry of defiance, answering to the crow of the cock, is one of the rudest and least sympathetic sounds which is heard among the birds. Its only merit is that it can be heard very far. It is readily audible at the distance of a mile when it breaks the stillness of a summer night. At present the bird seems out of favor. At best it is a beautiful but annoying ornament to pleasure-grounds. It is likely, indeed, that it may in time become limited to its native wildernesses and to zo?logical gardens.

From Africa we have derived one rather uncommon tenant of our barnyards and fields, the guinea-hen. This creature, though of convenient size, hardy, and commendable from the number of eggs it lays, has never won a large place in the esteem of our rural people, and is now not much kept, except in some parts of the Southern States of this country. The difficulty with this creature, as with the peacock, is that it is not truly domesticated; though it will not betake itself altogether to the woods, it prefers to maintain a half-wild habit. It will not, if it can possibly avoid it, lay its eggs in any place where they are likely to be found by man. Moreover, their rude and little-modulated cries are in the summer season almost incessant, and the din which a considerable flock can produce is exceedingly vexatious. They thus do not fit the needs or comfort of man to the degree which is likely to give them a permanent place among his associates.

The last considerable addition to our barnyards has come to us in the form of the turkey. This species has the peculiar distinction of being the only animal form of definite use to man over a wide field which has been contributed from the life of the New World. Although the creature was much hunted by our North American Indians, and is of a type which lends itself to domestication, it does not appear to have become a companion of man until it was taken from the West India Islands to Europe shortly after the discovery of this country. Thence the domesticated form appears to have been returned to this country, where it has been a favorite in a measure unknown in the Old World. Ornithologists deem the Cuban turkey, whence our tame form came, to be specifically distinct from those which are found on the mainland of this continent. Although these kinds are distinguishable by plumage, they are probably only varieties of a common species. This is indicated by the fact that our tame flocks readily intermingle with their wild kindred.

The ease with which the turkey becomes domesticated is remarkable. In this regard the creature may be compared to our cocks and hens. In both cases the tamableness is doubtless to be explained by the fact that the primitive forms dwelt in permanent association, the movements of which were in a way controlled by the adult males, and by the fact that the forms had abandoned the use of wings for wide-ranging flight. The change which has been brought about in the turkeys with their adoption into the human association has been slight. No distinct varieties of breeds have been originated, though here and there the observer may note slight local variations in the coloration of the plumage, which are probably due to varying admixtures with the wild forms of our forests. Thus in Kentucky and other parts of the South, where the opportunities for the intermingling of blood of the tame and wild forms are frequent, the domesticated creatures often resemble so nearly the wilderness forms that even the wary hunter may make mistakes as to whether the bird he sights be fair game or not. Unless carefully watched, a drove of these creatures on the border of the wilderness is apt gradually to return to the wild state, the three or four centuries of life about the home of man not having been sufficient to do away with their ancient love of freedom.

Among the English folk of North America the turkeys found a large place as an element of the food-supply. It has become curiously associated with the Puritan festival of Thanksgiving, an institution which has spread throughout the United States and which has in a way taken the place of the harvest-home festivities of the Old World and bygone ages. It is probable that the relation of this bird to our national festivities has done much to keep it in use in this country. It is a well-recognized fact that it is costly to keep and that the eggs are not desirable for culinary use. The species requires a wide range. It does not do well in the confined conditions in which cocks and hens can readily be maintained. It therefore is not likely to be kept in any region where the agriculture is of a high grade. It is best suited to farms where there are considerable areas of half-wild pastures.

Although the turkey is a truly gregarious form, its mental endowments are of a lower grade than those of most social birds. Their calls are few in number and have little of that conversational quality which we note in those of our ordinary barnyard fowls. Although the males contest the field with each other by personal combats, they are not very valiant, the creatures trusting for favor with the females rather to the parade of their plumage and the pomp of their carriage than to the wager of battle. In the matter of show they are, however, very effective, being surpassed only by the peacock in the splendor of their attire. In their domesticated state they lose much of the beauty which they have in the wilderness, as they do their pristine dimensions. Those who have hunted our wild species are likely to remember scenes where in some forest glade they have beheld a gobbler displaying his graces to an admiring harem. As he struts about with his tail feathers erect and his neck arched back, now and then pausing to utter an exultant gobble, the spectacle is one of the most amusing displays of animal pride which the naturalist has a chance to behold.

Recent experiments in ostrich farming seem to indicate that we are on the eve of introducing into our "happy family" the noblest remaining member of that group of great birds which characterized the life of the later geological periods. As yet the efforts in taming ostriches are too new for us to tell just what the effect of man's skill on the development of this creature will be. It is evident, however, that the creature can be won from its wilderness state, at least to something like the imperfect companionship with man which has been attained by the guinea-fowls and turkeys. All we know of the variations in plumage of birds indicates that the breeder's art may bring about great changes in the highly decorative feathers for which this bird is to be reared. It is also probable that with the better food which domestic conditions imply, this wanderer of the desert may be brought to attain a very much greater size than it wins in the hard life of its native land. If the form should prove as plastic as that of our ordinary barnyard species, we may indeed succeed in developing a variety approaching in dimensions the gigantic moa of New Zealand, or the aepyornis of Madagascar, those magnificent creatures of the past which passed away just before their native lands were known to our race. The variations in size of the wild ostrich appear to indicate that this interesting result may be attainable.

Next after the cocks and hens the most important birds of economic value have come from the water fowl. In this field there are great opportunities for domestication, only a few of which have been adequately used. The aquatic birds, save for the fact that they are in all cases inspired with a more or less strong migratory humor, lend themselves to the shaping hand of man more readily than most other forms. These creatures have the habit of association in a much more perfect way than our ground birds. They normally dwelt in rather close order and in relations which are necessarily very sympathetic. Whoever has watched the flight of wild geese must have remarked the beautiful way in which they arrange at once for close companionship and for safety in the violent movements which impel their heavy bodies at high speed through the air. In the order of their flight the alignment is more perfect than in the march of trained soldiers. Each bird keeps as near to his neighbor as possible; but manages always to preserve the interval which will insure against a collision of the strong and swift-moving wings, an accident which might well disable them for flight. I have repeatedly undertaken to confound their motion by firing a rifle bullet at the head of the moving wedge. Although the sound of the projectile, if well directed, will disturb their processional order, it never brings confusion. The startled birds sink down or rise above the plane of the air in which their comrades are moving, but they never strike against them.

The admirable sense of interval which the wild birds exhibit in their flight is to be seen also when they move over the surface of the water, where the fleet of living forms is always so arranged that each individual does not interfere with its neighbor. I recall with much pleasure an occasion when, from a ship becalmed in a thick fog off the southern shore of Labrador, within sound of the breakers, I undertook to find something about the lay of the land and the chance of harborage by paddling in a small boat toward the shore. I had hardly lost sight of the ship when my boat glided into an assemblage of eider ducks, where the mothers, with their fledgling young, were lazily swimming to and fro, as if to practise the ducklings in the art of swimming. Each brood appeared to have its own space of water, and between each of the chicks there was likewise a less but equally well measured interval. The same features of orderly association, which I have just noted in the swimming and flying of these wild birds, may be seen in a somewhat degraded state in our domesticated varieties of the group. They all indicate in these forms a keen sense of their neighbors and a habit of association based upon sympathetic emotions.

The sympathetic quality of our water fowl, at least in that part of the emotion which leads them to be concerned with the afflictions of their species, appears to be more distinct than in the case of our ordinary barnyard fowl. Geese, as is well known, will make common cause against an intruder from whom harm to the flock may be expected. Their simultaneous din when anything occurs to arouse their enmity is commemorated in the ancient myth concerning the aid which they gave in the defence of the walls of Rome. There are anecdotes apparently well attested where water fowl have borne away a wounded comrade which had fallen before the huntsman's fowling-piece. In Smiles's "Life of Edwards" there is an often-quoted story which appears to be trustworthy and sufficiently illustrates this point. A hunter, having shot one of a flock of terns, which fell wounded into the water near the shore, waded in to seize it. Suddenly two of the terns came to their wounded companion, seized him by either wing, and bore him toward the open sea. When these two helpers were weary, the sufferer was lowered into the water, and, in turn, seized by two other birds which were fresh for the labor. Working in succession, these birds carried their companion to a rock some distance from the shore. When the hunter endeavored to approach the rock, yet others of the species seized the cripple and bore him far beyond reach.

Although too much value must not be given to the numerous anecdotes concerning the sagacity of water fowl, the great mass of these stories, as compared with the poverty of the anecdotes concerning the better-known barnyard creatures, seems to establish the fact that their intelligence is much greater than that of the land birds. This superiority can probably be attributed to the fact that their life requires much more definite adaptation of means to ends than in the simpler conditions which are met by the forms which dwell in the fields. The circumstances of their life are something like those of the seals among mammals. They have to do with the conditions of the air, the land, and the water; and as they generally undertake long migrations, the range of the things they have to accommodate themselves to is great, and the effect of their labor is decidedly educative.

As yet, from the great number of species of water fowl man has really domesticated but two characteristic groups, the species of geese and of ducks. Swans have been brought to a state where they tolerate the presence of man, though they rarely establish any really intimate relations with him. Some other species, as, for instance, the grebe, have been taught to dwell about the homes of man, accepting food from his hands. It is likely that more of these water fowl would have come into human associations were it not for the fact that they are naturally migratory, and when, after a season of domestication, they join a passing flock, they never return to the place where they have been kept.

The swan, like the peacock, has been bred for ornament rather than for use. In fact, the bird has no other merit than its exceeding grace. We cannot believe that much pains was ever taken with this creature to break up the migratory instincts which are common in the wild kindred species. We have to suppose that the bird in its pristine form was without the impulse to undertake distant journeys in the winter season, or that it abandoned ancient habits with no great difficulty. We obtain some light on this point by noting the fact that among the migratory species it not infrequently happens that, while the greater number of individuals undertake the annual journey, certain of them will remain on the ground where they were born. Those which remain would be more likely to mate with those which were like-minded than with others that journeyed afar. In this way small local breeds might well be originated which would differ from their migratory kindred not only in the measure of the wandering instincts, but in the capacity for flight which their kindred preserve. There is some reason to believe that this process of selection naturally and somewhat frequently takes place. In certain cases it may lay the foundation of new species, or at least of distinct varieties; more commonly, however, the individuals which have abandoned the migratory life are likely to perish from the severity of climate or the other unfavorable conditions that their mates avoid by their wanderings.

It is a characteristic of all the doves that their young are born in a very immature state, and for some time after they come from the egg they have to be supplied with food which has been partly digested in the crop or upper part of the stomach of the parent. For the proper rearing of the brood there is required the assiduous care of both parents. Therefore quite naturally we find among these birds that the pairing habit is well developed, and as they rear several broods each season, that the mating is for life. Although there are numbers of birds in various orders which are accustomed to the monogamic habit, it happens that the pigeon is the only animal which man has ever won to true domestication in which the sexes can be thus permanently united. In the dovecote, however many birds it may contain, the breeder can be always sure as to the parentage of the young which he is rearing. This affords an admirable basis for the practice of his art, which is still further favored by the fact that pigeons reproduce rapidly and the progeny are ready to mate in a few months after they come into the world. Thus the species affords really ideal conditions for that process of selection on which the improvement of all domesticated animals intimately depends.

Selective breeding of pigeons began in India, as the records seem to show, more than two thousand years ago. Though other animals have been brought to domestication at much earlier times, this appears to have been the first of them to be subjected to deliberate efforts on the part of their masters, which were intended to bring about in a methodical way certain changes in their forms and habits. The most curious part of this great endeavor which has been applied to breeding pigeons is found in the fact that the ends sought have no utility, but afford satisfaction from the point of view of pure diversion or the gratification of taste. We are well accustomed to the action of such motives upon our flowering plants of the garden, but the pigeon is the only animal where fancy has labored for thousands of years for its gratification. The breeders of pigeons from remote antiquity to the present day appear to have had no definite purpose in all their pains. They have taken the chance variations in form and habit and endeavored to extend these sports of nature by a careful system of mating those in which the singular features were most evident. Thus the fan-tail breed has been developed until the creatures display their unornamental tail feathers with all the dignity with which a peacock shows his marvellous decorations. The pouters have in some unaccountable way learned to take air into their crop; and the habit has been developed by selection until the bird destroys all trace of his original shapeliness, though he seems to take pride in his diseased appearance. The tumbler, probably derived from some ancestor afflicted with a disease of an epileptic character, manages to go through his convulsions in the air without serious consequences and apparently with some pleasure to himself. There are over one hundred less conspicuous varieties, of which only one deserves notice, and this for the reason that it has some possible utility to man and is now much attended to. This is known as the carrier pigeon.

In early time, before the invention of the railway and telegraph, some ingenious breeder of pigeons, observing the constant way in which these creatures returned to the place where they were bred, invented the plan of using them to convey information. This service was found convenient not only for ordinary correspondence, but was exceedingly valuable where a place was beleaguered by an enemy. In such cases carrier pigeons could often be used to convey information across the otherwise impassable lines. Even in modern times, as, for instance, during the last siege of Paris, these swift and sure flying birds proved of great use in keeping up communications between the people of the invested town and the French armies in the field. Letters in cipher, sometimes photographed down until the characters were microscopically fine, were made into packages of small weight in order not to impede the flight of the bird, carefully affixed to its body, and thus sent away. Very generally these curious shipments came to the hands of those for whom they were destined. The birds can be trusted to fly at night; they retain for a long time the memory of their home, and spare no pains to return to it.

The homing power of the carrier pigeon appears to be a special development of a natural capacity, as is also its swiftness and endurance in flight. Our other breeds and the wild species whence they have all come are not disposed to undertake long journeys; they rarely, indeed, wander far from their abiding places. Our experience with the carriers shows how readily the creatures may be educated to perform feats which they were not accustomed to do in their wild state. Something of the same elasticity of constitution may be observed in the bodies of our pigeons as they have been affected by selection. Not only has the plumage been greatly altered by the breeder's art and in pursuance of his plans, but the form and proportions of the bones have coincidently and unintentionally been greatly changed. So considerable are these alterations that if these creatures were submitted for dissection to a naturalist who knew nothing of the history of the bird, he would have no hesitation in classing them as belonging not only in different species, but as members of diverse genera.
