The following instance will show how little suspicion of man the vizcachas have. A few years ago I went out shooting them on three consecutive evenings. I worked in a circle, constantly revisiting the same burrows, never going a greater distance from home than could be walked in four or five minutes. During the three evenings I shot sixty vizcachas dead; and probably as many more escaped badly wounded into their burrows; for they are hard to kill, and however badly wounded, if sitting near the burrow when struck, are almost certain to escape into it. But on the third evening I found them no wilder, and killed about as many as on the first. After this I gave up shooting them in disgust; it was dull sport, and to exterminate or frighten them away with a gun seemed an impossibility.

It is a very unusual thing to eat the vizcacha, most people, and especially the gauchos, having a silly unaccountable prejudice against their flesh. I

have found it very good, and while engaged writing this chapter have dined on it served up in various ways. The young animals are rather insipid, the old males tough, but the mature females are excellent--the flesh being tender, exceedingly white, fragrant to the nostrils, and with a very delicate game-flavour.

Within the last ten years so much new land has been brought under cultivation that farmers have been compelled to destroy incredible numbers of vizcachas: many large "estancieros" (cattle-breeders) have followed the example set by the grain-growers, and have had them exterminated on their estates. Now all that Azara, on hearsay, tells about the vizcachas perishing in their burrows, when these are covered up, but that they can support life thus buried for a period of ten or twelve days, and that during that time animals will come from other villages and disinter them, unless frightened off with dogs, is strictly true. Country workmen are so well acquainted with these facts that they frequently undertake to destroy all the vizcacheras on an estate for so paltry a sum as ten-pence in English money for each one, and yet will make double the money at this work than they can at any other. By day they partly open up, then cover up the burrows with a great quantity of earth, and by night go round with dogs to drive away the vizcachas from the still open burrows that come to dig out their buried friends. After all the vizcacheras on an estate have been thus served, the workmen are usually bound by previous agreement to keep guard over them for a space of eight

or ten days before they receive their hire: for the animals covered up are then supposed to be all dead. Some of these men I have talked with have assured me that living vizcachas have been found after fourteen days--a proof of their great endurance. There is nothing strange, I think, in the mere fact of the vizcacha being unable to work his way out when thus buried alive; for, for all I know to the contrary, other species may, when their burrows are well covered up, perish in the same manner; but it certainly is remarkable that other vizcachas should come from a distance to dig out those that are buried alive. In this good office they are exceedingly zealous; and I have frequently surprised them after sunrise, at a considerable distance from their own burrows, diligently scratching at those that had been covered up. The vizcachas are fond of each other's society, and live peaceably together; but their goodwill is not restricted to the members of their own little community; it extends to the whole species, so that as soon as night comes many animals leave their own and go to visit the adjacent villages. If one approaches a vizcachera at night, usually some of the vizcachas on it scamper off to distant burrows: these are neighbours merely come to pay a friendly visit. This intercourse is so frequent that little straight paths are formed from one vizcachera to another. The extreme attachment between members of different communities makes it appear less strange that they should assist each other: either the desire to see, as usual, their buried neighbours becomes intense enough to impel them to work their way to them; or cries of

312 The Naturalist in La Plata.

distress from the prisoners reach and incite them to attempt their deliverance. Many social species are thus powerfully affected by cries of distress from one of their fellows; and some will attempt a rescue in the face of great danger--the weasel and the peccary for example.

Mild and sociable as the vizcachas are towards each other, each one is exceedingly jealous of any intrusion into his particular burrow, and indeed always resents such a breach of discipline with the utmost fury. Several individuals may reside in the compartments of the same burrow; but beyond themselves not even their next-door neighbour is permitted to enter; their hospitality ends where it begins, at the entrance. It is difficult to compel a vizcacha to enter a burrow not his own; even when hotly pursued by dogs they often refuse to do so. When driven into one, the instant their enemies retire a little space they rush out of it, as if they thought the hiding-place but little less dangerous than the open plain. I have frequently seen vizcachas, chased into the wrong burrows, summarily ejected by those inside: and sometimes they make their escape only after being well bitten for their offence.

I have now stated the most interesting facts I have collected concerning the vizcacha: when others rewrite its history they doubtless will, according to the opportunities of observation they enjoy, be able to make some additions to it, but probably none of great consequence. I have observed this species in Patagonia and Buenos Ayres only; and as I have found that its habits are considerably modified by

Biography of the Vizcacha,

313

circumstances in the different localities where I have met with it, I am sure that other variations will occur in the more distant regions, where the conditions vary.

The most remarkable thing to be said about the vizcacha is, that although regarded by Mr. Waterhouse, and others who have studied its affinities, as one of the lowest of the rodents, exhibiting strong Marsupial characters, the living animal appears to be more intelligent than other rodents, not of South America only, but also of those of a higher type in other continents. A parallel case is, perhaps, to be found in the hairy armadillo, an extremely versatile and intelligent animal, although only an edentate. And among birds the ypecaha--a large La Plata rail--might also be mentioned as an example of what ought not to be; for it is a bold and intelligent bird, more than a match for the fowl, both in courage and in cunning; and yet it is one of the family which Professor Parker--from the point of view of the anatomist--characterizes as a "feeble-minded, cowardly group."

CHAPTER XXI.

THE DYING HUANACO.

LEST any one should misread the title to this chapter, I hasten to say that the huanaco, or guanaco as it is often spelt, is not a perishing species; nor, as things are, is it likely to perish soon, despite the fact that civilized men, Britons especially, are now enthusiastically engaged in the extermination of all the nobler mammalians:--a very glorious crusade, the triumphant conclusion of which will doubtless be witnessed by the succeeding generation, more favoured in this respect than ours. The huanaco, happily for it, exists in a barren, desolate region, in its greatest part waterless and uninhabitable to human beings; and the chapter-heading refers to a singular instinct of the dying animals, in very many cases allowed, by the exceptional conditions in which they are placed, to die naturally.

And first, a few words about its place in nature and general habits. The huanaco is a small camel--small, that is, compared with its existing relation--without a hump, and, unlike the camel of the Old World, non-specializad; doubtless it is a very ancient animal on the earth, and for all we know to the contrary, may have existed contemporaneously with some of the earliest known representatives of the

The Dying Huanaco. 315

camel type, whose remains occur in the lower and upper miocene deposits--Poebrotherium, Protolabis, Procamelus, Pliauchenia, and Macrauchenia. It ranges from Tierra del Fuego and the adjacent islands, northwards over the whole of Patagonia, and along the Andes into Peru and Bolivia. On the great mountain chain it is both a wild and a domestic animal, since the llama, the beast of burden of the ancient Peruvians, is no doubt only a variety: but as man's slave it has changed so greatly from the original form that some naturalists have regarded the llama as a distinct species, which, like the camel of the East, exists only in a domestic state. It has had time enough to vary, as it is more than probable that the tamed and useful animal was inherited by the children of the sun from races and nations that came before them: and how far back Andean civilization extends may be inferred from the belief expressed by the famous American archaeologist, Squiers, that the ruined city of Tiahuanaco, in the vicinity of Lake Titicaca, is as old as Thebes and the Pyramids.

It is, however, with the wild animal, the huanaco, that I am concerned. A full-grown male measures seven to eight feet in length, and four feet high to the shoulder; it is well clothed in a coat of thick woolly hair, of a pale reddish colour, Longest and palest on the under parts. In appearance it is very unlike the camel, in spite of the long legs and neck; in its finely-shaped head and long ears, and its proud and graceful carriage, it resembles an antelope rather than its huge and, from an aesthetic point of view, deformed Asiatic relation. In habits

316 The Naturalist in La Plata.

it is gregarious, and is usually seen in small herds, but herds numbering several hundreds or even a thousand are occasionally met with on the stony, desolate plateaus of Southern Patagonia; but the huanaco is able to thrive and grow fat where almost any other herbivore would starve. While the herd feeds one animal acts as sentinel, stationed on the hillside, and on the appearance of danger utters a shrill neigh of alarm, and instantly all take to flight. But although excessively shy and wary they are also very inquisitive, and have enough intelligence to know that a single horseman can do them no harm, for they will not only approach to look closely at him, but will sometimes follow him for miles. They are also excitable, and at times indulge in strange freaks. Darwin writes:--"On the mountains of Tierra del Fuego I have more than once seen a huanaco, on being approached, not only neigh and squeal, but prance and leap about in a most ridiculous manner, apparently in defiance as a challenge." And Captain King relates that while sailing into Port Desire he witnessed a chase of a huanaco after a fox, both animals evidently going at their greatest speed, so that they soon passed out of sight. I have known some tame huanacos, and in that state they make amusing intelligent pets, fond of being caressed, but often so frolicsome and mischievous as to be a nuisance to their master. It is well known that at the southern extremity of Patagonia the huanacos have a dying place, a spot to which all individuals inhabiting the surrounding plains repair at the approach of death to deposit their bones. Darwin and Fitzroy first recorded

The Dying Huanaco. 317

this strange instinct in their personal narratives, and their observations have since been fully confirmed by others. The best known of these dying or burial-places are on the banks of the Santa Cruz and Gallegos rivers, where the river valleys are covered with dense primeval thickets of bushes and trees of stunted growth; there the ground is covered with the bones of countless dead generations. "The animals," says Darwin, "in most cases must have crawled, before dying, beneath and among the bushes." A strange instinct in a creature so preeminently social in its habits; a dweller all its life long on the open, barren plateaus and mountain sides! What a subject for a painter! The grey wilderness of dwarf thorn trees, aged and grotesque and scanty-leaved, nourished for a thousand years on the bones that whiten the stony ground at their roots; the interior lit faintly with the rays of the departing sun, chill and grey, and silent and motionless--the huanacos' Golgotha. In the long centuries, stretching back into a dim immeasurable past, so many of this race have journeyed hither from the mountain and the plain to suffer the sharp pang of death, that, to the imagination, something of it all seems to have passed into that hushed and mournful nature. And now one more, the latest pilgrim, has come, all his little strength spent in his struggle to penetrate the close thicket; looking old and gaunt and ghostly in the twilight; with long ragged hair; staring into the gloom out of death-dimmed sunken eyes. England has one artist who might show it to us on canvas, who would be able to catch the feeling of such a scene--of

318 The Naturalist in La Plata.

that mysterious, passionless tragedy of nature--I refer to J. M. Swan, the painter of the "Prodigal Son" and the "Lioness Defending her Cubs."

To his account of the animal's dying place and instinct, Darwin adds: "I do not at all understand the reason of this, but I may observe that the wounded huanacos at the Santa Cruz invariably walked towards the river."

It would, no doubt, be rash to affirm of any instinct that it is absolutely unique; but, putting aside some doubtful reports about a custom of the Asiatic elephant, which may have originated in the account of Sindbad the Sailor's discovery of an elephant's burial place, we have no knowledge of an instinct similar to that of the huanaco in any other animal. So far as we know, it stands alone and apart, with nothing in the actions of other species leading up, or suggesting any family likeness to it. But what chiefly attracts the mind to it is its strangeness. It looks, in fact, less like an instinct of one of the inferior creatures than the superstitious observance of human beings, who have knowledge of death, and believe in a continued existence after dissolution; of a triba that in past times had conceived the idea that the liberated spirit is only able to find its way to its future abode by starting at death from the ancient dying-place of the tribe or family, and thence moving westward, or skyward, or underground, over the well-worn immemorial track, invisible to material eyes.

But, although alone among animal instincts-in its strange and useless purpose--for it is as absolutely useless to the species or race as to the dying individual

THE DYING HUANACO.

[Page 3!8.

The Dying Huanaco. 319

--it is not the only useless instinct we know of: there are many others, both simple and complex; and of such instincts we believe, with good reason, that they once played an important part in the life of the species, and were only rendered useless by changes in the condition of life, or in the organism, or in both. In other words, when the special conditions that gave them value no longer existed, the correlated and perfect instinct was not, in these cases, eradicated, but remained, in abeyance and still capable of being called into activity by a new and false stimulus simulating the old and true. Viewed in this way, the huanaco's instinct might be regarded as something remaining to the animal from a remote past, not altogether unaffected by time perhaps; and like some ceremonial usage among men that has long ceased to have any significance, or like a fragment of ancient history, or a tradition, which in the course of time has received some new and false interpretation. The false interpretation, to continue the metaphor, is, in this case, that the purpose of the animal in going to a certain spot, to which it has probably never previously resorted, is to die there. A false interpretation, because, in the first place, it is incredible that an instinct of no advantage to the species, in its struggle for existence and predominance should arise and become permanent; and, in the second place, it is equally incredible that it could ever have been to the advantage of the species or race to, have a dying place. We must, then, suppose that there is in the sensations preceding death, when death comes slowly, some resemblance to the sensations experi-

320 The Naturalist in La Plata.

enced by the animal at a period when its curious instinct first took form and crystallized; these would be painful sensations that threatened life; and freedom from them, and safety to the animal, would only exist in a certain well-remembered spot. Further, we might assume that it was at first only the memory of a few individuals that caused the animals to seek the place of safety; that a habit was thus formed; that in time this traditional habit became instinctive, so that the animals, old and young, made their way unerringly to the place of refuge whenever the old danger returned. And such an instinct, slowly matured and made perfect to enable this animal to escape extinction during periods of great danger to mammalian life, lasting hundreds or even thousands of years, and destructive of numberless other species less hardy and adaptive than the generalized huanaco, might well continue to exist, to be occasionally called into life by a false stimulus, for many centuries after it had ceased to be of any advantage.

Once we accept this explanation as probable--namely, that the huanaco, in withdrawing from the herd to drop down and die in the ancient dying ground, is in reality only seeking an historically remembered place of refuge, and not of death--the action of the animal loses much of its mysterious character; we come on to firm ground, and find that we are no longer considering an instinct absolutely unique, with no action or instinct in any other animal leading up or suggesting any family likeness to it, as I said before. We find, in fact, that there is at least one very important and very

The Dying Huanaco. 321

well-known instinct in another class of creatures, which has a strong resemblance to that of the huanaco, as I have interpreted it, and which may even serve to throw a side light on the origin of the huanaco's instinct. I refer to a habit of some ophidians, in temperate and cold countries, of returning annually to hybernate in the saine den.

A typical instance is that of the rattlesnake in the colder parts of North America. On the approach of winter these reptiles go into hiding, and it has been observed that in some districts a very large number of individuals, hundreds, and even thousands, will repair from the surrounding country to the ancestral den. Here the serpents gather in a mass to remain in a wholly or semi-torpid condition until the return of spring brings them out again, to scatter abroad to their usual summer haunts. Clearly in this case the knowledge of the hyberna-ting den is not merely traditional--that is, handed down from generation to generation, through the young each year following the adults, and so forming the habit of repairing at certain seasons to a certain place; for the young serpent soon abandons its parent to lead an independent life; and on the approach of cold weather the hybernating den may be a long distance away, ten or twenty, or even thirty miles from the spot in which it was born. The annual return to the hybernating den is then a fixed unalterable instinct, like the autumnal migration of some birds to a warmer latitude. It is doubtless favourable to the serpents to hybernate in large numbers massed together; and the habit of resorting annually to the same spot once formed,

322 The Naturalist in La Plata.

we can imagine that the individuals--perhaps a single couple in the first place--frequenting some very deep, dry, and well-sheltered cavern, safe from enemies, would have a great advantage over others of their race; that they would be stronger and increase more, and spread during the summer months further and further from the cavern on all sides; and that the further afield they went the more would the instinct be perfected; since all the young serpents that did not have the instinct of returning unerringly to the ancestral refuge, and that, like the outsiders of their race, to put it in that way, merely crept into the first hole they found on the approach of the cold season, would be more liable to destruction. Probably most snakes get killed long before a natural decline sets in; to say that not one in a thousand dies of old age would probably be no exaggeration; but if they were as safe from enemies and accidents as some less prolific and more highly-organized animals, so that many would reach the natural term of life, and death came slowly, we can imagine that in such a heat-loving creature the failure of the vital powers would simulate the sensations caused by a falling temperature, and cause the old or sick serpent, even in midsummer, to creep instinctively away to the ancient refuge, where many a long life-killing frost had been safely tided over in the past.

The huanaco has never been a hybernating animal; but we must assume that, like the crotalus of the north, he had formed a habit of congregating with his fellows at certain seasons at the same spot;

The Dying Huanaco. 323

further, that these were seasons of suffering to the animal--the suffering, or discomfort and danger, having in the first place given rise to the habit. Assuming again that the habit had existed so long as to become, like that of the reptile, a fixed, immutable instinct, a hereditary knowledge, so that the young huanacos, untaught by the adults, would go alone and unerringly to the meeting-place from any distance, it is but an easy step to the belief, that after the conditions had changed, and the refuges were no longer needed, this instinctive knowledge would still exist in them, and that they would take the old road when stimulated by the pain of a wound; or the miserable sensations experienced in disease or during the decay of the life-energy, when the senses grow dim, and the breath fails, and the blood is thin and cold.

I presume that most persons who have observed animals a great deal have met with cases in which the animal has acted automatically, or instinctively, when the stimulus has been a false one. I will relate one such case, observed by myself, and which strikes me as being apposite to the question I am considering. It must be premised that this is an instance of an acquired habit; but this does not affect my argument, since I have all along assumed that the huanaco--a highly sagacious species in the highest class of vertebrates--first acquired a habit from experience of seeking a remembered refuge, and that such habit was the parent, as it were, or the first clay model, of the perfect and indestructible instinct that was to be.

It is not an uncommon thing in the Argentino

Y 2

324 The Naturalist in La Plata,

pampas--I have on two occasions witnessed it myself--for a riding-horse to come home, or to the gate of his owner's house, to die. I am speaking of riding-horses that are never doctored, nor treated mercifully; that look on their master as an enemy rather than a friend; horses that live out in the open, and have to be hunted to the corral or enclosure, or roughly captured with a lasso as they run, when their services are required. I retain a very vivid recollection of the first occasion of witnessing an action of this kind in a horse, although I was only a boy at the time. On going out one summer evening I saw one of the horses of the establishment standing unsaddled and unbridled leaning his head over the gate. Going to the spot, I stroked his nose, and then, turning to an old native who happened to be near, asked him what could be the meaning of such a thing. "I think he is going to die," he answered; "horses often come to the house to die." And next morning the poor beast was found lying dead not twenty yards from the gate; although he had not appeared ill when I stroked his nose on the previous evening; but when I saw him lying there dead, and remembered the old native's words, it seemed to me as marvellous and inexplicable that a horse should act in that way, as if some wild creature--a rhea, a fawn, or dolichotes--had come to exhale his last breath at the gates of his enemy and constant persecutor, man.

I now believe that the sensations of sickness and approaching death in the riding-horse of the pampas resemble or similate the pains, so often experienced, of hunger, thirst and fatigue combined,

The Dying Huanaco. 325

together with the oppressive sensations caused by the ponderous native saddle, or recado, with its huge surcingle of raw hide drawn up so tightly as to hinder free respiration. The suffering animal remembers how at the last relief invariably came, when the twelve or fifteen hours' torture were over, the toil and the want, and when the great iron bridle and ponderous gear were removed, and he had freedom and food and drink and rest. At the gate or at the door of his master's house, the sudden relief had always come to him; and there does he sometimes go in his sickness, his fear overmastered by his suffering, to find it again.

Discussing this question with a friend, who has a subtle mind and great experience of the horse in semi-barbarous countries, and of many other animals, wild and tame, in many regions of the globe, he put forward a different explanation of the action of the horse in coming home to die, which he thinks simpler and more probable than mine. It is, that a dying or ailing animal instinctively withdraws itself from its fellows--an action of self-preservation in the individual in opposition to the well-known instincts of the healthy animals, which impels the whole herd to turn upon and persecute the sickly member, thus destroying its chances of recovery. The desire of the suffering animal is not only to leave its fellows, but to get to some solitary place where they cannot follow, or would never find him, to escape at once from a great and pressing danger. But on the pastoral pampas, where horses are so numerous that on that level, treeless area they are always and everywhere visible, no hiding-place

326 The Naturalist in La Plata.

is discoverable. In such a case, the animal, goaded by its instinctive fear, turns to the one spot that horses avoid; and although that spot has hitherto been fearful to him, the old fear is forgotten in the present and far more vivid one; the vicinity of his master's house represents a solitary place to him, and he seeks it, just as the stricken deer seeks the interior of some close forest, oblivious for the time, in its anxiety to escape from the herd, of the dangers lurking in it, and which he formerly avoided.

I have not set this explanation down merely because it does credit to my friend's ingenuity, but because it strikes me that it is the only alternative explanation that can be given of the animal's action in coming home to die. Another fact concerning the ill-tamed and barbarously treated horses of the pampas, which, to my mind, strengthens the view I have taken, remains to be mentioned. It is not an uncommon thing for one of these horses, after escaping, saddled and bridled, and wandering about for anight or night and day on the plains, to return of its own accord to the house. It is clear that in a case of this kind the animal comes home to seek relief. I have known one horse that always had to be hunted like a wild animal to be caught, and that invariably after being saddled tried to break loose, to return in this way to the gate after wandering about, saddled and bridled, for over twenty hours in uncomfortable freedom.

The action of the riding-horse returning to a master he is accustomed to fly from, as from an enemy, to be released of saddle and bridle, is, no doubt more intelligent than that of the dying horse

The Dying Huanaco. 327

coming home to be relieved from his sufferings, but the motive is the same in both cases; at the gate the only pain the animal has ever experienced has invariably begun, and there it has ended, and when the spur of some new pain afflicts him--new and yet like the old--it is to the well-remembered hated gate that it urges him.

To return to the huanaco. After tracing the dying instinct back to its hypothetical origin--namely, a habit acquired by the animal in some past period of seeking refuge from some kind of pain and danger at a certain spot, it is only natural to speculate a little further as to the nature of that danger and of the conditions the animal existed in.

If the huanaco is as old on the earth as its antique generalized form have led naturalists to suppose, we can well believe that it has survived not only a great many lost mammalian types, but many changes in the conditions of its life. Let us then imagine that at some remote period a change took place in the climate of Patagonia, and that it became colder and colder, owing to some cause affecting only that portion of the antarctic region; such a cause, for instance, as a great accumulation of icebergs on the northern shores of the antarctic continent, extending century by century until a large portion of the now open sea became blocked up with solid ice. If the change was gradual and the snow became deeper each winter and lasted longer, an intelligent, gregarious, and exceedingly hardy and active animal like the huanaco, able to exist on the driest woody fibres, would stand the beat chance of maintaining its existence in such altered conditions,

328 The Naturalist in La Plata.

and would form new habits to meet the new danger. One would be that at the approach of a period of deep snow and deadly cold, all the herds frequenting one place would gather together at the most favourable spots in the river valleys, where the vegetation is dense and some food could be had while the surrounding country continued covered with deep snow. They would, in fact, make choice of exactly such localities as are now used for dying places. There they would be sheltered from the cutting-winds, the twigs and bark would supply them with food, the warmth from a great many individuals massed together would serve to keep the snow partially melted under foot, and would prevent their being smothered, while the stiff and closely interlaced branches would keep a roof of snow above them, and thus protected they would keep alive until the return of mild weather released them. In the course of many generations all weakly animals, and all in which the habit of seeking the refuge at the proper time was weak or uncertain in its action would perish, but their loss would be an advantage to the survivors.

It is worthy of remark that it is only at the southern extremity of Patagonia that the huanacos have dying places. In Northern Patagonia, and on the Chilian and Peruvian Andes no such instinct has been observed.

CHAPTER XXII.

THE STRANGE INSTINCTS OF CATTLE.

MY purpose in this paper is to discuss a group of curious and useless emotional instincts of social animals, which have not yet been properly explained. Excepting two of the number, placed first and last in the list, they are not related in their origin; consequently they are here grouped together arbitrarily, only for the reason that we are very familiar with them on account of their survival in our domestic animals, and because they are, as I have said, useless; also because they resemble each other, among the passions and actions of the lower animals, in their effect on our minds. This is in all cases unpleasant, and sometimes exceedingly painful, as when species that rank next to ourselves in their developed intelligence and organized societies, such as elephants, monkeys, dogs, and cattle, are seen under the domination of impulses, in some cases resembling insanity, and in others simulating the darkest passions of man.

These instincts are:--

(1) The excitement caused by the smell of blood, noticeable in horses and cattle among our domestic animals, and varying greatly in degree, from an

330 The Naturalist in La Plata.

emotion so slight as to be scarcely perceptible to the greatest extremes of rage or terror.

(2) The angry excitement roused in some animals when a scarlet or bright-red cloth is shown to them. So well known is this apparently insane instinct in our cattle that it has given rise to a proverb and metaphor familiar in a variety of forms to everyone.

(3) The persecution of a sick or weakly animal by its companions.

(4) The sudden deadly fury that seizes on the herd or family at the sight of a companion in extreme distress. Herbivorous mammals at such times will trample and gore the distressed one to death. In the case of wolves, and other savage-tempered carnivorous species, the distressed fellow is frequently torn to pieces and devoured on the spot.

To take the first two together. When we consider that blood is red; that the smell of it is, or may be, or has been, associated with that vivid hue in the animal's mind; that blood, seen and smelt is, or has been, associated with the sight of wounds and with cries of pain and rage or terror from the wounded or captive animal, there appears at first sight to be some reason for connecting these two instinctive passions as having the same origin--namely, terror and rage caused by the sight of a member of the herd struck down and bleeding, or struggling for life in the grasp of an enemy. I do not mean to say that such an image is actually present in the animal's mind, but that the inherited or instinctive passion is one in kind and in its work-

The Strange Instincts of Cattle. 331

ing with the passion of the animal when experience and reason were its guides.

But the more I consider the point the more am I inclined to regard these two instincts as separate in their origin, although I retain the belief that cattle and horses and several wild animals are violently excited by the smell of blood for the reason just given--namely, their inherited memory associates the smell of blood with the presence among them of some powerful enemy that threatens their life. To this point I shall return when dealing with the last and most painful of the instincts I am considering.

The following incident will show how violently this blood passion sometimes affects cattle, when they are permitted to exist in a half-wild condition, as on the pampas. I was out with my gun one day, a few miles from home, when I came across a patch on the ground where the grass was pressed or trodden down and stained with blood. I concluded that some thievish gauchos had slaughtered a fat cow there on the previous night, and, to avoid detection, had somehow managed to carry the whole of it away on their horses. As I walked on, a herd of cattle, numbering about three hundred, appeared moving slowly on towards a small stream a mile away; they were travelling in a thin long line, and would pass the blood-stained spot at a distance of seven to eight hundred yards, but the wind from it would blow across their track. When the tainted wind struck the leaders of the herd they instantly stood still, raising their heads, then broke out into loud excited bellowings;

332 The Naturalist in La Plata.

and finally turning they started off at a fast trot, following up the scent in a straight line, until they arrived at the place where one of their kind had met its death. The contagion spread, and before long all the cattle were congregated on the fatal spot, and began moving round in a dense mass, bellowing continually.

It may be remarked here that the animal has a peculiar language on occasions like this; it emits a succession of short bellowing cries, like excited exclamations, followed by a very loud cry, alternately sinking into a hoarse murmur, and rising to a kind of scream that grates harshly on the sense. Of the ordinary "cow-music" I am a great admirer, and take as much pleasure in it as in the cries and melody of birds and the sound of the wind in trees; but this performance of cattle excited by the smell of blood is most distressing to hear.

The animals that had forced their way into the centre of the mass to the spot where the blood was, pawed the earth, and dug it up with their horns, and trampled each other down in their frantic excitement. It was terrible to see and hear them. The action of those on the border of the living mass in perpetually moving round in a circle with dolorous bellowings, was like that of the women in an Indian village when a warrior dies, and all night they shriek and howl with simulated grief, going round and round the dead man's hut in an endless procession.

The "bull and red rag" instinct, as it may be called, comes next in order.

The Strange Instincts of Cattle. 333

It is a familiar fact that brightness in itself powerfully attracts most if not all animals. The higher mammalians are affected in the same way as birds and insects, although not in the same degree. This fact partly explains the rage of the bull. A scarlet flag fluttering in the wind or lying on the grass attracts his attention powerfully, as it does that of other animals; but though curious about the nature of the bright object, it does not anger him. His anger is excited--and this is the whole secret of the matter--when the colour is flaunted by a man; when it forces him to fix his attention on a man, i.e. an animal of another species that rules or drives him, and that he fears, but with only a slight fear, which may at any moment be overcome by his naturally bold aggressive disposition, Not only does the vivid colour compel him to fix his attention on the being that habitually interferes with his liberty, and is consequently regarded with unfriendly eyes, but it also produces the illusion on his mind that the man is near him, that he is approaching him in an aggressive manner: it is an insult, a challenge, which, being of so explosive a temper, he is not slow to accept.

On the pampas I was once standing with some gauchos at the gate of a corral into which a herd of half-wild cattle had just been driven. One of the men, to show his courage and agility, got off his horse and boldly placed himself in the centre of the open gate. His action attracted the attention of one of the nearest cows, and lowering her horns she began watching him in a threatening manner. He then suddenly displayed the scarlet lining of his

334 The Naturalist in La Plata.

poncho, and instantly she charged him furiously: with a quick movement to one side he escaped her horns, and after we had driven her back, resumed his former position and challenged her again in the same way. The experiment was repeated not less than half a dozen times, and always with the same result. The cattle were all in a savage temper, and would have instantly charged him on his placing himself before them on foot without the display of scarlet cloth, but their fear of the mounted men, standing with lassos in their hand on either side of him, kept them in check. But whenever the attention of any one individual among them was forcibly drawn to him by the display of vivid colour, and fixed on him alone, the presence of the horsemen was forgotten and fear was swallowed by rage. It is a fact, I think, that most animals that exhibit angry excitement when a scarlet rag is flourished aggressively at them, are easily excited to anger at all times. Domestic geese and turkeys may be mentioned among birds: they do not fly at a grown person, but they will often fly at a child that challenges them in this way; and it is a fact that they do not at any time fear a child very much and will sometimes attack him without being challenged. I think that the probability of the view I have taken is increased by another fact--namely, that the sudden display of scarlet colour sometimes affects timid animals with an extreme fear, just as, on the other hand, it excites those that are bold and aggressive to anger. Domestic sheep, forinstance, that vary greatly in disposition in different races or breeds, and even in different individuals, may be

The Strange Instincts of Cattle. 335

affected in the two opposite ways, some exhibiting extreme terror and others only anger at a sudden display of scarlet colour by the shepherd or herder.

The persecution of a sick animal by its companions comes next under consideration.

It will have been remarked, with surprise by some readers, no doubt, that I have set down as two different instincts this persecution of a sick or weakly individual by its fellows, and the sudden deadly rage that sometimes impels the herd to turn upon and destroy a wounded or distressed companion. It is usual for writers on the instincts of animals to speak of them as one: and I presume that they regard this sudden deadly rage of several individuals against a companion as merely an extreme form of the common persecuting instinct or impulse. They are not really one, but are as distinct in origin and character as it is possible for any two instincts to be. The violent and fatal impulse starts simultaneously into life and action, and is contagious, affecting all the members of the herd like a sudden madness. The other is neither violent nor contagious: the persecution is intermittent: it is often confined to one or to a very few members of the herd, and seldom joined in by the chief member, the leader or head to whom all the others give way.

Concerning this head of the herd, or flock, or pack, it is necessary to say something more. Some gregarious animals, particularly birds, live together in the most perfect peace and amity; and here no leader is required, because in their long association together as a species in flocks, they have attained to a oneness of mind, so to speak, which causes them

336 The Naturalist in La Plata.

to move or rest, and to act at all times harmoniously together, as if controlled and guided by an extrane-ous force. I may mention that the kindly instinct in animals, which is almost universal between male and female in the vertebrates, is most apparent in these harmoniously acting birds. Thus, in La Plata, I have remarked, in more than one species, that a lame or sick individual, unable to keop pace with the flock and find its food, has not only been waited for, but in some cases some of the flock have constantly attended it, keeping close to it both when flying and on the ground; and, I have no doubt, feeding it just as they would have fed their young.

Naturally among such kinds no one member is of more consideration than another. But among mammals such equality and harmony is rare. The instinct of one and all is to lord it over the others, with the result that one more powerful or domineering gets the mastery, to keep it thereafter as long as he can. The lower animals are, in this respect, very much like us; and in all kinds that are at all fierce-tempered the mastery of one over all, and of a few under him over the others, is most salutary; indeed, it is inconceivable that they should be able to exist together under any other system.

On cattle-breeding establishments on the pampas, where it is usual to keep a large number of fierce-tempered dogs, I have observed these animals a great deal, and presume that they are very much like feral dogs and wolves in their habits. Their quarrels are incessant; but when a fight begins the head of the pack as a rule rushes to the

The Strange Instincts of Cattle. 337

spot, whereupon the fighters separate and march off in different directions, or else cast themselves down and deprecate their tyrant's wrath with abject gestures and whines. If the combatants are both strong and have worked themselves into a mad rage before their head puts in an appearance, it may go hard with him: they know him no longer, and all he can do is to join in the fray; then, if the fighters turn on him, he may be so injured that his power is gone, and the next best dog in the pack takes his place. The hottest contests are always between dogs that are well matched; neither will give place to the other, and so they fight it out; but from the foremost in strength and power down to the weakest there is a gradation of authority; each one knows just how far he can go, which companion he can bully when he is in a bad temper or wishes to assert himself, and to which he must humbly yield in his turn. In such a state the weakest one must always yield to all the others, and cast himself down, seeming to call himself a slave and worshipper of any other member of the pack that chooses to snarl at him, or command him to give up his bone with a good grace.

This masterful or domineering temper, so common among social mammals, is the cause of the persecution of the sick and weakly. When an animal begins to ail he can no longer hold his own; he ceases to resent the occasional ill-natured attacks made on him; his non-combative condition is quickly discovered, and he at once drops down to a place below the lowest; it is common knowledge

in the herd that he may be buffeted with impunity by all, even by those that have hitherto suffered buffets but have given none. But judging from my own observation, this persecution, is not, as a rule, severe, and is seldom fatal.

It is often the case that a sick or injured animal withdraws and hides himself from the herd; the instinct of the "stricken deer" this might be called. But I do not think that we need assume that the ailing individual goes away to escape the danger of being ill-used by his companions. He is sick and drooping and consequently unfit to be with the healthy and vigorous; that is the simplest and probably the true explanation of his action; although in some cases he might be driven from them by persistent rough usage. However peaceably gregarious mammals may live together, and however fond of each other's company they may be, they do not, as a rule, treat each other gently. Furthermore, their games are exceedingly rough and require that they shall be in a vigorous state of health to escape injury. Horned animals have no buttons to the sharp weapons they prod and strike each other with in a sportive spirit. I have often witnessed the games of wild and half-wild horses with astonishment; for it seemed that broken bones must result from the sounding kicks they freely bestowed on one another. This roughness itself would be a sufficient cause for the action of the individual, sick and out of tune and untouched by the glad contagion of the others, in escaping from them; and to leave them would be to its advantage (and to that of the race) since, if not fatally injured or sick unto death, its

The Strange Instincts of Cattle. 339

chances of recovery to perfect health would be thereby greatly increased.

It remains now to speak of that seemingly most cruel of instincts which stands last on my list. It is very common among gregarious animals that are at all combative in disposition, and still survives in our domestic cattle, although very rarely witnessed in England. My first experience of it was just before I had reached the age of five years. I was not at that early period trying to find out any of nature's secrets, but the scene I witnessed printed itself very vividly on my mind, so that I can recall it as well as if my years had been five-and-twenty; perhaps better. It was on a summer's evening, and I was out by myself at some distance from the house, playing about the high exposed roots of some old trees; on the other side of the trees the cattle, just returned from pasture, were gathered on the bare level ground. Hearing a great commotion among them, I climbed on to one of the high exposed roots, and, looking over, saw a cow on the ground, apparently unable to rise, moaning and bellowing in a distressed way, while a number of her companions were crowding round and goring her.

What is the meaning of such an instinct? Darwin has but few words on the subject. "Can we believe," he says, in his posthumous Essay on Instinct, "when a wounded herbivorous animal returns to its own herd and is then attacked and gored, that this cruel and very common instinct is of any service to the species?" At the same time, he hints that such an instinct might in some circumstances be useful, and his hint has been developed into the current belief

340

The Naturalist in La Plata.

among naturalists on the subject. Here it is, in Dr. Romanes' words: "We may readily imagine that the instinct displayed by many herbivorous animals of goring sick and wounded companions, is really of use in countries where the presence of weak members in a herd is a source of danger to the herd from the prevalence of wild beasts." Here it is assumed that the sick are set upon and killed, but this is not the fact; sickness and decay from age or some other cause are slow things, and increase imperceptibly, so that the sight of a drooping member grows familiar to the herd, as does that of a member with some malformation, or unusual shade of colour, or altogether white, as in the case of an albino.

Sick and weak members, as we have seen, while subject to some ill-treatment from their companions (only because they can be ill-treated with impunity), do not rouse the herd to a deadly animosity; the violent and fatal attack is often as not made on a member in perfect health and vigour and unwounded, although, owing to some accident, in great distress, and perhaps danger, at the moment.

The instinct is, then, not only useless but actually detrimental; and, this being so, the action of the herd in destroying one of its members is not even to be regarded as an instinct proper, but rather as an aberration of an instinct, a blunder, into which animals sometimes fall when excited to action in unusual circumstances.

The first thing that strikes us is that in these wild abnormal moments of social animals, they are acting in violent contradiction to the whole tenor of their lives; that in turning against a distressed

The Strange Instincts of Cattle, 341

fellow they oppose themselves to the law of their being, to the whole body of instincts, primary and secondary, and habits, which have made it possible for them to exist together in communities. It is, I think, by reflecting on the abnormal character of such an action that we are led to a true interpretation of this "dark saying of Nature."

Every one is familiar with Bacon's famous passage about the dog, and the noble courage which that animal puts on when "maintained by a man; who is to him in place of a God, or melior natura; which courage is manifestly such as that creature, without the confidence of a better nature than its own, could never attain." Not so. The dog is a social animal, and acts instinctively in concert with his fellows; and the courage he manifests is of the family, not the individual. In the domestic state the man he is accustomed to associate with and obey stands to him in the place of the controlling pack, and to his mind, which is canine and not human, is the pack. A similar "noble courage," greatly surpassing that exhibited on all other occasions, is displayed by an infinite number of mammals and birds of gregarious habits, when repelling the attacks of some powerful and dangerous enemy, or when they rush to the rescue of one of their captive fellows. Concerning this rage and desperate courage of social animals in the face of an enemy, we see (1) that it is excited by the distressed cries, or by the sight of a member of the herd or family dying from or struggling in the clutches of an enemy; (2) that it affects animals when a number af individuals are together, and is eminently con-

342 The Naturalist in La Plata.

tagious, like fear, that communicates itself, quick as lightning, from one to another until all are in a panic, and like the joyous emotion that impels the members of a herd or flock to rush simultaneously into play.

Now, it is a pretty familiar fact that animals acting instinctively, as well as men acting intelligently, have at times their delusions and their illusions, and see things falsely, and are moved to action by a false stimulus to their own disadvantage. When the individuals of a herd or family are excited to a sudden deadly rage by the distressed cries of one of their fellows, or by the sight of its bleeding wounds and the smell of its blood, or when they see it frantically struggling on the ground, or in the cleft of a tree or rock, as if in the clutches of a powerful enemy, they do not turn on it to kill but to rescue it.

In whatever way the rescuing instinct may have risen, whether simply through natural selection or, as is more probable, through an intelligent habit becoming fixed and hereditary, its effectiveness depends altogether on the emotion of overmastering rage excited in the animal--rage against a tangible visible enemy, or invisible, and excited by the cries or struggles of a suffering companion; clearly, then, it could not provide against the occasional rare accidents that animals meet with, which causes them to act precisely in the way they do when seized or struck down by an enemy. An illusion is the result of the emotion similar to the illusion produced by vivid expectation in ourselves, which has caused many a man to see in a friend and companion the

The Strange Instincts of Cattle. 343

adversary he looked to see, and to slay him in his false-seeing anger.

An illusion just as great, leading to action equally violent, but ludicrous rather than painful to witness, may be seen in dogs, when encouraged by a man to the attack, and made by his cries and gestures to expect that some animal they are accustomed to hunt is about to be unearthed or overtaken; and if, when they are in this disposition, he cunningly exhibits and sets them on a dummy, made perhaps of old rags and leather and stuffed with straw, they will seize, worry, and tear it to pieces with the greatest fury, and without the faintest suspicion of its true character.

That wild elephants will attack a distressed fellow seemed astonishing to Darwin, when he remembered the case of an elephant after escaping from a pit helping its fellow to escape also. But it is precisely the animals, high or low in the organic scale, that are social, and possess the instinct of helping each other, that will on occasions attack a fellow in misfortune--such an attack being no more than a blunder of the helping instinct.

Felix de Azara records a rather cruel experiment on the temper of some tame rats confined in a cage. The person who kept them caught the tail of one of the animals and began sharply pinching it, keeping his hand concealed under the cage. Its cries of pain and struggles to free itself greatly excited the other rats; and after rushing wildly round for some moments they flew at their distressed companion, and fixing their teeth in its throat quickly dispatched it. In this case if the

344 The Naturalist m La Plata.

hand that held the tail had been visible and in the cage, the bites would undoubtedly have been inflicted on it; but no enemy was visible; yet the fury and impulse to attack an enemy was present in the animals. In such circumstances, the excitement must be discharged--the instinct obeyed, and in the absence of any other object of attack the illusion is produced and it discharges itself on the struggling companion. It is sometimes seen in dogs, when three or four or five are near together, that if one suddenly utters a howl or cry of pain, when no man is near it and no cause apparent, the others run to it, and seeing nothing, turn round and attack each other. Here the exciting cause--the cry for help--is not strong enough to produce the illusion which is sometimes fatal to the suffering member; but each dog mistakingly thinks that the others, or one of the others, inflicted the injury, and his impulse is to take the part of the injured animal. If the cry for help--caused perhaps by a sudden cramp or the prick of a thorn--is not very sharp or intense, the other dogs will not attack, but merely look and growl at each other in a suspicious way.

To go back to Azara's anecdote. Why, it may be asked--and this question has been put to me in conversation--if killing a distressed companion is of no advantage to the race, and if something must be attacked--why did not these rats in this instance attack the cage they were shut in, and bite at the woodwork and wires? Or, in the case related by Mr. Andrew Lang in Longman's Magazine some time ago, in which the members of a herd of cattle in Scotland turned with sudden amazing fury on

The Strange Instincts of Cattle. 345

one of the cows that had got wedged between two rocks and was struggling with distressed bellowings to free itself--why did they not attack the prisoning rocks instead of goring their unfortunate comrade to death? For it is well known that animals will, on occasions, turn angrily upon and attack inanimate objects that cause them injury or hinder their freedom of action. And we know that this mythic faculty--the mind's projection of itself into visible nature--survives in ourselves, that there are exceptional moments in our lives when it comes back to us; no one, for instance, would be astonished to hear that any man, even a philosopher, had angrily kicked away or imprecated a stool or other inanimate object against which he had accidentally barked his shins. The answer is, that there is no connection between these two things--the universal mythic faculty of the mind, and that bold and violent instinct of social animals of rushing to the rescue of a stricken or distressed companion, which has a definite, a narrow, purpose--namely, to fall upon an enemy endowed not merely with the life and intelligence common to all things, including rocks, trees, and waters, but with animal form and motion.

I had intended in this place to give other instances, observed in several widely-separated species, including monkeys; but it is not necessary, as I consider that all the facts, however varied, are covered by the theory I have suggested--even a fact I like the one mentioned in this chapter of cattle bellowing and madly digging up the ground where the blood of one of their kind had been spilt: also such a fact as that of wild cattle and other

346 The Naturalist in La Plata.

animals caught in a trap or enclosure attacking and destroying each other in their frenzy; and the fact that some fierce-tempered carnivorous mammals will devour the companion they have killed. It is an instinct of animals like wolves and peccaries to devour the enemy they have overcome and slain: thus, when the jaguar captures a peccary out of a drove, and does not quickly escape with his prize into a tree, he is instantly attacked and slain and then consumed, even to the skin and boues. This is the wolf's and the peccary's instinct; and the devouring of one of their own companions is an inevitable consequence of the mistake made in the first place of attacking and killing it. In no other circumstances, not even when starving, do they prey on their own species.

If the explanation I have offered should seem a true or highly probable one, it will, I feel sure, prove acceptable to many lovers of animals, who, regarding tins seemingly ruthless instinct, not as an aberration but as in some vague way advantageous to animals in their struggle for existence, are yet unable to think of it without pain and horror; indeed, I know those who refuse to think of it at all, who would gladly disbelieve it if they could.

It should be a relief to them to be able to look on it no longer as something ugly and hateful, a blot on nature, but as an illusion, a mistake, an unconscious crime, so to speak, that has for its motive the noblest passion that animals know--that sublime courage and daring which they exhibit in defence of a distressed companion. This fiery spirit in animals, which makes them forget their own

The Strange Instincts of Cattle. 347

safety, moves our hearts by its close resemblance to one of the most highly-prized human virtues; just as we are moved to intellectual admiration by the wonderful migratory instinct in birds that simulates some of the highest achievements of the mind of man. And we know that this beautiful instinct is also liable to mistakes--that many travellers leave us annually never to return. Such a mistake was undoubtedly the cause of the late visitation of Pallas' sand-grouse: owing perhaps to some unusual atmospheric or dynamic condition, or to some change in the nervous system of the birds, they deviated widely from their usual route, to scatter in countless thousands over the whole of Europe and perish slowly in climates not suited to them; while others, overpassing the cold strange continent, sped on over colder, stranger seas, to drop at last like aerolites, quenching their lives in the waves.

Whether because it is true, as Professor Freeman and some others will have it, that humanity is a purely modern virtue; or because the doctrine of Darwin, by showing that we are related to other forms of life, that our best feelings have their roots low down in the temper and instincts of the social species, has brought us nearer in spirit to the inferior animals, it is certain that our regard for them has grown, and is growing, and that new facts and fresh inferences that make us think more highly of them are increasingly welcome.

CHAPTER XXIII.

HORSE AND MAN.

THERE is no mode of progression so delightful as riding on horseback. Walking, rowing, bicycling are pleasant exercises in their way, but the muscular exertion and constant exercise of judgment they call for occupy the mind partly to the exclusion of other things; so that a long walk may sometimes be only a long walk and nothing more. In riding we are not conscious of exertion, and as for that close observation and accurate discernment necessary in traversing the ground with speed and safety, it is left to the faithful servant that carries us. Pitfalls, hillocks, slippery places, the thousand little inequalities of the surface that have to be measured with infallible eye, these disturb us little. To fly or go slowly at will, to pass unshaken over rough and smooth alike, fording rivers without being wet, and mounting hills without climbing, this is indeed unmixed delight. It is the nearest approach to bird-life we seem capable of, since all the monster bubbles and flying fabrics that have been the sport of winds from the days of Montgolfier downwards have brought us no nearer to it. The aeronaut gasping for breath above the clouds offers only a sad spectacle of the imbecility of science and man's

Horse and Man. 349

shattered hopes. To the free inhabitants of air we can only liken the mounted Arab, vanishing, hawklike, over the boundless desert.

In riding there is always exhilarating motion; yet, if the scenery encountered be charming, you are apparently sitting still, while, river-like, it flows toward and past you, ever giving place to fresh visions of beauty. Above all, the mind is free, as when one lies idly on the grass gazing up into the sky. And, speaking of myself, there is even more than this immunity from any tax on the understanding such as we require in walking; the rhythmic motion, the sensation as of night, acting on the brain like a stimulus. That anyone should be able to think better lying, sitting, or standing, than when speeding along on horseback, is to me incomprehensible. This is doubtless due to early training and long use; for on those great pampas where I first saw the light and was taught at a tender age to ride, we come to look on man as a parasitical creature, fitted by nature to occupy the back of a horse, in which position only he has full and free use of all his faculties. Possibly the gaucho--the horseman of the pampas--is born with this idea in his brain; if so, it would only be reasonable to suppose that its correlative exists in a modification of structure. Certain it is that an intoxicated gaucho lifted on to the back of his horse is perfectly safe in his seat. The horse may do his best to rid himself of his burden; the rider's legs--or posterior arms as they might appropriately be called--retain their iron grip, notwithstanding the fuddled brain.

350

The Naturalist in La Plata.

The gaucho is more or less bow-legged; and, of course, the more crooked his legs are, the better for him in his struggle for existence. Off his horse his motions are awkward, like those of certain tardigrade mammals of arboreal habits when removed from their tree. He waddles in his walk;
