his hands feel for the reins; his toes turn inwards like a duck's. And here, perhaps, we can see why foreign travellers, judging him from their own standpoint, invariably bring against him the charge of laziness. On horseback he is of all men most active. His patient endurance under privations

that would drive other men to despair, his laborious days and feats of horsemanship, the long journeys he performs without rest or food, seem to simple dwellers on the surface of the earth almost like miracles. Deprive him of his horse, and he can do nothing but sit on the ground cross-legged, or en cuclillas,--on his heels. You have, to use his own figurative language, cut off his feet.

Darwin in his earlier years appears not to have possessed the power of reading men with that miraculous intelligence always distinguishing his researches concerning other and lower orders of beings. In the Voyage of a Naturalist, speaking of this supposed indolence of the gauchos, he tells that in one place where workmen were in great request, seeing a poor gaucho sitting in a listless attitude, he asked him why he did not work. The man's answer was that he was too poor to work! The philosopher was astonished and amused at the reply, but failed to understand it. And yet, to one acquainted with these lovers of brief phrases, what more intelligible answer could have been returned? The poor fellow simply meant to say that his horses had been stolen--a thing of frequent occurrence in that country, or, perhaps, that some minion of the Government of the moment had seized them for the use of the State.

To return to the starting point, the pleasures of riding do not flow exclusively from the agreeable sensations attendant on flight-like motion; there is also the knowledge, sweet in itself, that not a mere cunningly fashioned machine, like that fabled horse of brass "on which the Tartar king did ride,"

352 The Naturalist in La Plata.

sustains us; but a something with life and thought, like ourselves, that feels what we feel, understands us, and keenly participates in our pleasures. Take, for example, the horse on which some quiet old country gentleman is accustomed to travel; how soberly and evenly he jogs along, picking his way over the ground. But let him fall into the hands of a lively youngster, and how soon he picks up a frisky spirit! Were horses less plastic, more the creatures of custom than they are, it would always be necessary, before buying one, to inquire into the disposition of its owner.

When I was thirteen years old I was smitten with love for a horse I once saw--an untamable-looking brute, that rolled his eyes, turbulently, under a cloud of black mane tumbling over his forehead. I could not take my sight off this proud, beautiful creature, and I longed to possess him with a great longing. His owner--a worthless vagabond, as it happened--marked my enthusiastic admiration, and a day or two afterwards, having lost all his money at cards, he came to me, offering to sell me the horse. Having obtained my father's consent, I rushed off to the man with all the money I possessed--about thirty or thirty-five shillings, I believe. After some grumbling, and finding he could get no more, he accepted the money. My new possession filled me with unbounded delight, and I spent the time caressing him and leading him about the grounds in search of succulent grasses and choice leaves to feed him on. I am sure this horse understood and loved me, for, in spite of that savage look, which his eyes never quite lost,

Horse and Man, 353

he always displayed a singular gentleness towards me. He never attempted to upset me, though he promptly threw--to my great delight, I must confess--anyone else who ventured to mount him. Probably the secret of his conduct was that he hated the whip. Of this individual, if not of the species, the celebrated description held true:--"The horse is a docile animal, but if you flog him he will not do so." After he had been mine a few days, I rode on him one morning to witness a cattle-marking on a neighbouring estate. I found thirty or forty gauchos on the ground engaged in catching and branding the cattle. It was rough, dangerous work, but apparently not rough enough to satisfy the men, so after branding an animal and releasing him from their lassos, several of the mounted gauchos would, purely for sport, endeavour to knock it down as it rushed away, by charging furiously on to it. As I sat there enjoying the fun, my horse stood very quietly under me, also eagerly watching the sport. At length a bull was released, and, smarting from the fiery torture, lowered his horns and rushed away towards the open plain. Three horsemen in succession shot out from the crowd, and charged the bull at full speed; one by one, by suddenly swerving his body round, he avoided them, and was escaping scot-free. At this moment my horse--possibly interpreting a casual touch of my hand on his neck, or some movement of my body, as a wish to join in the sport--suddenly sprang forward and charged on the flying bull like a thunderbolt, striking him full in the middle of his body, and hurling him with a tremendous shock to

354 The Naturalist in La Plata.

earth. The stricken beast rolled violently over, while my horse stood still as a stone watching him. Strange to say, I was not unseated, but, turning-round, galloped back, greeted by a shout of applause from the spectators--the only sound of that description I have ever had the privilege of listening to. They little knew that my horse had accomplished the perilous feat without his rider's guidance. No doubt he had been accustomed to do such things, and, perhaps, for the moment, had forgotten that he had passed into the hands of a new owner--one of tender years. He never voluntarily attempted an adventure of that kind again; he knew, I suppose, that he no longer carried on his back a reckless dare-devil, who valued not life. Poor Picáso! he was mine till he died. I have had scores of horses since, but never one I loved so well.

With the gauchos the union between man and horse is not of so intimate a nature as with the Indians of the pampas. Horses are too cheap, where a man without shoes to his feet may possess a herd of them, for the closest kind of friendship to ripen. The Indian has also less individuality of character. The immutable nature of the conditions he is placed in, and his savage life, which is a perpetual chase, bring him nearer to the level of the beast he rides. And probably the acquired sagacity of the horse in the long co-partnership of centuries has become hereditary, and of the nature of an instinct. The Indian horse is more docile, he understands his master better; the slightest touch of the hand on his neck, which seems to have

Horse and Man. 355

developed a marvellous sensitiveness, is sufficient to guide him. The gaucho labours to give his horse "a silken mouth," as he aptly calls it; the Indian's horse has it from birth. Occasionally the gaucho sleeps in the saddle; the Indian can die on his horse. During frontier warfare one hears at times of a dead warrior being found and removed with difficulty from the horse that carried him out of the fight, and about whose neck his rigid fingers were clasped in death. Even in the gaucho country, however, where, I grieve to confess, the horse is not deservedly esteemed, there are very remarkable instances of equine attachment and fidelity to man, and of a fellowship between horse and rider of the closest kind. One only I will relate.

When Rosas, that man of "blood and iron," was Dictator of the Argentine country--a position which he held for a quarter of a century--desertors from the army were inexorably shot when caught, as they generally were. But where my boyhood was spent there was a deserter, a man named Santa Anna, who for seven years, without ever leaving the neighbourhood of his home, succeeded in eluding his pursuers by means of the marvellous sagacity and watchful care exercised by his horse. When taking his rest on the plain--for he seldom slept under a roof--his faithful horse kept guard. At the first sight of mounted men on the horizon he would fly to his master, and, seizing his cloak between his teeth, rouse him with a vigorous shake. The hunted man would start up, and in a moment man and horse would vanish into one of the dense reed-beds

A a 2

abounding in the place, and where no man could follow. I have not space to tell more about this horse; but at last, in the fulness of time, when the figs were ripe--literally as well as figuratively, for it happened in the autumn of the year--the long tyrannous rule ended, and Santa Anna came out of the reed-beds, where he had lived his wild-animal life, to mix with his fellows. I knew him some years later. He was a rather heavy-looking man, with little to say, and his reputation for honesty was not good in the place; but I dare say there was something good in him.

Students of nature are familiar with the modifying effects of new conditions on man and brute. Take, for example, the gaucho: he must every day traverse vast distances, see quickly, judge rapidly, be ready at all times to encounter hunger and fatigue, violent changes of temperature, great and sudden perils. These conditions have made him differ widely from the peasant of the Peninsula; he has the endurance and keen sight of a wolf, is fertile in expedients, quick in action, values human life not at all, and is in pain or defeat a Stoic. Unquestionably the horse he rides has also suffered a great change. He differs as much from the English hunter, for instance, as one animal can well differ from another of the same species. He never pounds the earth and wastes his energies in vain parade. He has not the dauntless courage that performs such brilliant feats in the field, and that often as not attempts the impossible. In the chase he husbands all his strength, carrying his head low, and almost grazing the ground with his hoofs, so that he is not a showy animal. Con-

stant use, or the slow cumulative process of natural selection, has served to develop a keenness of sense almost preternatural. The vulture's eye, with all the advantage derived from the vulture's vast elevation above the scene surveyed, is not so far-reaching as the sense of smell in the pampa horse. A common phenomenon on the pampas is a sudden migration of the horses of a district to some distant place. This occurs in seasons of drought, when grass or

water fails. The horses migrate to some district where, from showers having fallen or other circumstances, there is a better supply of food and drink. A slight breeze blowing from the more favoured region, which may be forty or fifty miles away, or even much further, is enough to start them off. Yet, during the scorching days of midsummer, very little moisture or smell of grass can possibly reach them from such a distance.

Another phenomenon, even more striking, is familiar to every frontiersman. For some reason, the gaucho horse manifests the greatest terror at an Indian invasion. No doubt his fear is, in part at any rate, an associate feeling, the coming of the Indians being always a time of excitement and com-motion, sweeping like a great wave over the country; houses are in flames, families flying, cattle being driven at frantic speed to places of greater safety. Be this as it may, long before the marauders reach the settlement (often when they are still a whole day's journey from it) the horses take the alarm and come wildly flying in: the contagion quickly spreads to the horned cattle, and a general stampede ensues. The gauchos maintain that the horses smell

358 The Naturalist in La Plata.

the Indians. I believe they are right, for when passing a distant Indian camp, from which the wind blew, the horses driven before me have suddenly taken fright and run away, leading me a chase of many miles. The explanation that ostriches, deer, and other fleet animals driven in before the invaders might be the cause of the stampede cannot be accepted, since the horses are familiar with the sight of these animals flying from their gaucho hunters.

There is a pretty fable of a cat and dog lying in a dark room, aptly illustrating the fine senses of these two species. "Listen! I heard a feather drop!" said the dog. "Oh, no!" said the cat, "it was a needle; I saw it." The horse is not commonly believed to have senses keen as that, and a dog tracing his master's steps over the city pavement is supposed to be a feat no other animal can equal. No doubt the artificial life a horse lives in England, giving so little play to many of his most important faculties, has served to blunt them. He is a splendid creature; but the noble bearing, the dash and reckless courage that distinguish him from the modest horse of the desert, have not been acquired without a corresponding loss in other things. When ridden by night the Indian horse--and sometimes the same habit is found in the gaucho's animal--drops his head lower and lower as the darkness increases, with the danger arising from the presence of innumerable kennels concealed in the grass, until his nose sweeps the surface like a foxhound's. That this action is dictated by a powerful instinct of self-preservation is plain; for, when I have attempted to forcibly drag the animal's head up, he has answered such an

Horse and Man. 359

experiment by taking the bit in his teeth, and violently pulling the reins out of my hand. His miraculous sense of smell measures the exact position of every hidden kennel, every treacherous spot, and enables him to pass swiftly and securely over it.

On the desert pampa the gaucho, for a reason that he knows, calls the puma the "friend of man." The Arab gives this designation to his horse; but in Europe, where we do not associate closely with the horse, the dog naturally takes the foremost place in our affections. The very highest praise yet given to this animal is probably to be found in Bacon's essay on Atheism. "For take an example of a dog," he says, "and mark what a generosity and courage he will put on when he finds himself 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!" Can we not say as much of the horse? The very horses that fly terror-stricken from the smell of an Indian will, when "maintained by a man," readily charge into a whole host of yelling savages.

I once had a horse at home, born and bred on the place, so docile that whenever I required him I could go to him where the horses were at pasture, and, though they all galloped off at my approach, he would calmly wait to be caught. Springing on to his back, I would go after the other horses, or gallop home with only my hand on his neck to guide him. I did not often ride him, as he was slow and lazy, but with timid women and children he was a favourite; he was also fre-

360 The Naturalist in La Plata,

quently used for farm work, in or out of harness, and I could shoot from his back. In the peach season he would roam about the plantation, getting the fruit, of which he was very fond, by tugging at the lower branches of the trees and shaking it down in showers. One intensely dark night I was riding home on this horse. I came through a road with a wire fence on each side, two miles in length, and when I had got nearly to the end of this road my horse suddenly stopped short, uttering a succession of loud terrified snorts. I could see nothing but the intense blackness of the night before me. and tried to encourage him to go on. Touching him on the neck, I found his hair wet with the sudden profuse sweat of extreme fear. The whip made no impression on him. He continued to back away, his eyes apparently fixed on some object of horror just before him, while he trembled to such a degree that I was shaken in the saddle. He attempted several times to wheel round and run away, but I was determined not to yield to him, and continued the contest. Suddenly, when I was beginning to despair of getting home by that road, he sprang forward, and regularly charged the (to me) invisible object before him, and in another moment, when he had apparently passed it, taking the bit between his teeth he almost flew over the ground, never pausing till he brought me to my own door. When I dismounted his terror seemed gone, but he hung his head in a dejected manner, like a horse that has been under the saddle all day. I have never witnessed another such instance of almost maddening fear. His terror and apprehension were like what we can imagine a man experiencing at sight of a ghost in some dark solitary place.

Horse and Man. 361

Yet he did not forcibly carry me away from it, as he might so easily have done; but, finding himself maintained by a "nature superior to his own," he preferred to face it. I have never met in the dog a more striking example of this noblest kind of brute courage. The incident did not impress me very much at the moment, but when I came to reflect that my sight was mere blindness compared with that of my horse, and that it was not likely his imagination clothed any familiar natural object with fantastic terrors, it certainly did impress me very deeply.

I am loth to finish with, my subject, in which, to express myself in the manner of the gauchos, I have passed over many matters, like good grass and fragrant herbs the galloping horse sniffs at but cannot stay to taste; and especially loth to conclude with this last incident, which has in it an element of gloom. I would rather first go back for a few moments to my original theme--the pleasures of riding, for the sake of mentioning a species of pleasure my English reader has probably never tasted or even heard of. When riding by night on the pampas, I used to enjoy lying back on my horse till my head and shoulders rested well on his back, my feet also being raised till they pressed against his neck; and in this position, which practice can make both safe and comfortable, gaze up into the starry sky. To enjoy this method of riding thoroughly, a sure-footed unshod horse with perfect confidence in his rider is necessary; and he must be made to go at a swift and smooth pace over level grassy ground. With these conditions the sensation is positively delightful. Nothing of earth is visible, only the vast circle of

362 The Naturalist in La Plata.

the heavens glittering with innumerable stars; the muffled sound of the hoofs on the soft sward becomes in fancy only the rushing of the wings of our Pegasus, while the enchanting illusion that we are soaring through space possesses the mind. Unfortunately, however, this method of riding is impracticable in England. And, even if people with enthusiasm enough could be found to put it in practice by importing swift light-footed Arabian or pampa horses, and careering about level parks on dark starry nights, probably a shout of derision would be raised against so undignified a pastime.

Apropos of dignity, I will relate, in conclusion, an incident in my London life which may possibly interest psychologists. Some time ago in Oxford Street I got on top of an omnibus travelling west. My mind was preoccupied, I was anxious to get home, and, in an absent kind of way, I became irritated at the painfully slow rate of progress. It was all an old familiar experience, the deep thought, lessening pace, and consequent irritation. The indolent brute I imagined myself riding was, as usual, taking advantage of his rider's abstraction; but I would soon "feelingly persuade" him that I was not so far gone as to lose sight of the difference between a swinging gallop and a walk. So, elevating my umbrella, I dealt the side of the omnibus a sounding blow, very much to the astonishment of my fellow-passengers. So overgrown are we with usages, habits, tricks of thought and action springing from the soil we inhabit; and when we have broken away and removed ourselves far from it, so long do the dead tendrils still cling to us!

CHAPTER XXIV,

SEEN AND LOST,

WE can imagine what the feelings of a lapidary would be--an enthusiast whose life is given to the study of precious stones, and whose sole delight is in the contemplation of their manifold beauty--if a stranger should come in to him, and, opening his hand, exhibit a new unknown gem, splendid as ruby or as sapphire, yet manifestly no mere variety of any familiar stone, but differing as widely from all others as diamond from opal or cat's-eye; and then, just when he is beginning to rejoice in that strange exquisite loveliness, the hand should close and the stranger, with a mocking smile on his lips, go forth and disappear from sight in the crowd. A feeling such as that would be is not unfrequently experienced by the field naturalist whose favoured lot it is to live in a country not yet "thoroughly worked out," with its every wild inhabitant scientifically named, accurately described, and skilfully figured in some colossal monograph. One swift glance of the practised eye, ever eagerly searching for some new-thing, and he knows that here at length is a form never previously seen by him; but his joy is perhaps only for a few moments, and the prize is snatched from sight for ever. The lapidary might

364 The Naturalist in La Plata,

have some doubts; he might think that the stranger had, after all, only mocked him with the sight of a wonderful artificial gem, and that a close examination would have proved its worthlessness; but the naturalist can have no doubts: if he is an enthusiast, well acquainted with the fauna of his district, and has good eyesight, he knows that there is no mistake; for there it is, the new strange form, photographed by instantaneous process on his mind, and there it will remain, a tantalizing image, its sharp lines and fresh colouring unblurred by time.

Walking in some open forest glade, he may look up just in time to see a great strange butterfly--a blue Morpho, let us say, wandering in some far country where this angel insect is unknown--passing athwart his vision with careless, buoyant flight, the most sylph-like thing in nature, and all blue and pure like its aerial home, but with a more delicate and wonderful brilliance in its cerulean colour, giving such unimaginable glory to its broad airy wings; and then, almost before his soul has had time to feel its joy, it may soar away unloitering over the tall trees, to be seen no more.

But the admiration, the delight, and the desire are equally great, and the loss just as keenly felt, whether the strange species seen happens to be one surpassingly beautiful or not. Its newness is to the naturalist its greatest attraction. How beautiful beyond all others seems a certain small unnamed brown bird to my mind! So many years have passed and its image has not yet grown dim; yet I saw it only for a few moments, when it hopped out

from, the thick foliage and perched within two or three yards of me, not afraid, but only curious; and after peering at me first with one eye and then the other, and wiping its small dagger on a twig, it flew away and was seen no more. For many days I sought for it, and for years waited its reappearance, and it was more to me than ninety and nine birds which I had always known; yet it was very modest, dressed in a brown suit, very pale on the breast and white on the throat, and for distinction a straw-coloured stripe over the eye--that ribbon which Queen Nature bestows on so many of her feathered subjects, in recognition, I suppose, of some small and common kind of merit. If I should meet with it in a collection I should know it again; only, in that case it would look plain and homely to me--this little bird that for a time made all others seem unbeautiful.

Even a richer prize may come in sight for a brief period--one of the nobler mammalians, which are fewer in number, and bound to earth like ourselves, and therefore so much better known than the wandering children of air. In. some secluded spot, resting amidst luxuriant herbage or forest undergrowth, a slight rustling makes us start, and, lo! looking at us from the clustering leaves, a strange face; the leaf-like ears erect, the dark eyes round with astonishment, and the sharp black nose twitching and sniffing audibly, to take in the unfamiliar flavour of a human presence from the air, like the pursed-up and smacking lips of a wine-drinker tasting a new vintage. No sooner seen than gone, like a dream, a phantom, the quaint

366 The Naturalist in La Plata.

furry face to be thereafter only an image in memory.

Sometimes the prize may be a very rich one, and actually within reach of the hand--challenging the hand, as it were, to grasp it, and yet presently slip away to be seen no more, although it maybe sought for day after day, with a hungry longing comparable to that of some poor tramp who finds a gold doubloon in the forest, and just when he is beginning to realize all that it means to him drops it in the grass and cannot find it again. There is not the faintest motion in the foliage, no rustle of any dry leaf, and yet we know that something has moved--something has come or has gone; and, gazing fixedly at one spot, we suddenly see that it is still there, close to us, the pointed ophidian head and long neck, not drawn back and threatening, but sloping forward, dark and polished as the green and purple weed-stems springing from marshy soil, and with an irregular chain of spots extending down the side. Motionless, too, as the stems it is; but presently the tongue, crimson and glistening, darts out and flickers, like a small jet of smoke and flame, and is withdrawn; then the smooth serpent head drops down, and the thing is gone.

How I saw and lost the noble wrestling frog has been recounted in Chapter IV.: other tantalizing experiences of the same kind remain to be told in the present chapter, which is not intended for the severe naturalist, but rather for such readers as may like to hear something about the pains and pleasures of the seeker as well as the result of the seeking.

Seen and Lost.

367

One of my earliest experiences of seeing and losing relates to a humming-bird--a veritable "jewel of ornithology." I was only a boy at the time, but already pretty well acquainted with the birds of the district I lived in, near La Plata River, and among them were three species of the hummingbird. One spring day I saw a fourth--a wonderful little thing, only half as big as the smallest of the other three--the well-known Phaithornis splendens--and scarcely larger than a bumble-bee. I was within three feet of it as it sucked at the flowers,

suspended motionless in the air, the wings appearing formless and mist-like from their rapid vibratory motion, but the rest of the upper plumage was seen distinctly as anything can be seen. The head and neck and upper part of the back were emerald green, with the metallic glitter usually seen in the burnished scale-like feathers of these small birds; the lower half of the back was velvet-black; the tail and tail-coverts white as snow. On two other occasions, at intervals of a few days, I saw this brilliant little stranger, always very near, and tried without success

368 The Naturalist in La Plata.

to capture it, after which, it disappeared from the plantation. Four years later I saw it once again not far from the same place. It was late in summer, and I was out walking on the level plain where the ground was carpeted with short grass, and nothing else grew there except a solitary stunted cardoou thistle-bush with one flower on its central stem above the grey-green artichoke-like leaves. The disc of the great thorny blossom was as broad as that of a sunflower, purple in colour, delicately frosted with white; on this flat disc several insects were feeding--flies, fireflies, and small wasps--and I paused for a few minutes in my walk to watch them. Suddenly a small misty object flew swiftly downwards past my face, and paused motionless in the air an inch or two above the rim of the flower. Once more my lost humming-bird, which I remembered so well! The exquisitely graceful form, half circled by the misty moth-like wings, the glittering green and velvet-black mantle, and snow-white tail spread open like a fan--there it hung like a beautiful bird-shaped gem suspended by an invisible gossamer thread. One--two--three moments passed, while I gazed, trembling with rapturous excitement, and then, before I had time to collect my faculties and make a forlorn attempt to capture it with my hat, away it flew, gliding so swiftly on the air that form and colour were instantly lost, and in appearance it was only an obscure grey line traced rapidly along the low sky and fading quickly out ol sight. And that was the last I ever saw of it.

The case of this small "winged gem," still wandering nameless in the wilds, reminds me of yet

Seen and Lost. 369

another bird seen and lost, also remarkable for its diminutive size. For years I looked for it, and when the wished-for opportunity came, and it was in my power to secure it, I refrained; and Fate punished me by never permitting me to see it again. On several occasions while riding on the pampas I had caught glimpses of this minute bird flitting up mothlike, with uncertain tremulous flight, and again dipping into the weeds, tall grass, or thistles. Its plumage was yellowish in hue, like sere dead herbage, and its extremely slender body looked longer and slimmer than it was, owing to the great length of its tail, or of the two middle tail-feathers. I knew that it was a Synallaxis--a genus of small birds of the Woodhewer family. Now, as I have said in a former chapter, these are wise little birds, more interesting--I had almost said more beautiful--in their wisdom, or wisdom-simulating instincts, than the quatzel in its resplendent green, or the cock-of-the-rock in its vivid scarlet and orange mantle. Wrens and mocking-birds have melody for their chief attraction, and the name of each kind is, to our minds, also the name of a certain kind of sweet music; we think of swifts and swallows in connection with the mysterious migratory instinct; and humming-birds have a glittering mantle, and the miraculous motions necessary to display its ever-changing iridescent beauty. In like manner, the homely Dendrocolaptidae possess the genius for building, and an account of one of these small birds without its nest would be like a biography of Sir Christopher Wren that made no mention of his works. It was not strange then

370 The Naturalist in La Plata.

that when I saw this small bird the question rose to my mind, what kind of nest does it build?

One morning in the month of October, the great breeding-time for birds in the Southern Hemisphere, while cautiously picking my way through a bed of eardoon bushes, the mysterious little creature flitted up and perched among the clustering leaves quite near to me. It uttered a feeble grasshopper-like chirp; and then a second individual, smaller, paler-coloured, and if possible shyer than the first, showed itself for two or three seconds, after which both birds dived once more into concealment. How glad I was to see them! for here they were, male and female, in a suitable spot in my own fields, where they evidently meant to breed. Every day after that I paid them one cautious visit, and by waiting from five to fifteen minutes, standing motionless among the thistles, I always succeeded in getting them to show themselves for a few moments. I could easily have secured them then, but my wish was to discover their nesting habits; and after watching for some days, I was rewarded by finding their nest; then for three days more I watched it slowly progressing towards completion, and each time I approached it one of the small birds would flit out to vanish into the herbage. The structure was about six inches long, and not more than two inches in diameter, and was placed horizontally on a broad stiff eardoon leaf, sheltered by other leaves above. It was made of the finest dry grass loosely woven, and formed a simple perfectly straight tube, open at both ends. The aperture was so small that I could only insert my little finger, and the bird

could not, of course, have turned round in so narrow a passage, and so always went in at one end and left by the other. On visiting the spot on the fourth day I found, to my intense chagrin, that the delicate fabric had been broken and thrown down by some animal; also, that the birds had utterly

vanished--for I sought them in vain, both there and in every weedy and thistly spot in the neighbourhood. The bird without the nest had seemed a useless thing to possess; now, for all my pains, I had only a wisp of fine dry grass in my hand, and no bird. The shy, modest little creature, dwelling

violet-like amidst clustering leaves, and even when showing itself still "half-hidden from the eye," was thereafter to be only a tantalizing image in memory. Still, my case was not so hopeless as that of the imagined lapidary; for however rare a species may be, and near to its final extinction, there must always be many individuals existing, and I was cheered by the thought that I might yet meet with one at some future time. And, even if this particular species was not to gladden my sight again, there were others, scores and hundreds more, and at any moment I might expect to see one shining, a living gem, on Nature's open extended palm.

Sometimes it has happened that an animal would have been overlooked or passed by with scant notice, to be forgotten, perhaps, but for some singular action or habit which has instantly given it a strange importance, and made its possession desirable.

I was once engaged in the arduous and monotonous task of driving a large number of sheep a distance of two hundred and fifty miles, in excessively hot weather, when sheep prefer standing still to travelling. Five or six gauchos were with me, and we were on the southern pampas of Buenos Ayres, near to a long precipitous stony sierra which rose to a height of five or six hundred feet above the plain. Who that has travelled for eighteen days on a dead level in a broiling sun can resist a hill? That sierra was more sublime to us than Conon-dagua, than Illimani.

Leaving the sheep, I rode to it with three of the men; aad after securing our horses on the lower

Seen And Lost. 373

slope, we began our laborious ascent. Now the gaucho when taken from his horse, on which he lives like a kind of parasite, is a very slow-moving creature, and I soon left my friends far behind. Coming to a place where ferns and flowering herbage grew thick, I began to hear all about me sounds of a character utterly unlike any natural sound I was acquainted with--innumerable low clear voices tinkling or pealing like minute sweet-toned, resonant bells--for the sounds were purely metallic and perfectly bell-like. I was completely ringed round with the mysterious music, and as I walked it rose and sank rhythmically, keeping time to my steps. I stood still, and immediately the sounds ceased. I took a step forwards, and again the fairy-bells were set ringing, as if at each step my foot touched a central meeting point of a thousand radiating threads, each thread attached to a peal of little bells hanging concealed among the herbage. I waited for my companions, and called their attention to the phenomenon, and to them also it was a thing strange and perplexing. "It is the bell-snake!" cried one excitedly. This is the rattle-snake; but although at that time I had no experience of this reptile, I knew that he was wrong. Yet how natural the mistake! The Spanish name of "bell-snake" had made him imagine that the whirring sound of the vibrating rattles, resembling muffled cicada music, is really bell-like in character. Eventually we discovered that the sound was made by grasshoppers; but they were seen only to be lost, for I could not capture one, so excessively shy and cunning had the perpetual ringing of their own

374 The Naturalist in La Plata.

little tocsins made them. And presently I had to return to my muttons; and afterwards there was no opportunity of revisiting the spot to observe so singular a habit again and collect specimens. It was a very slender grasshopper, about an inch and a half long, of a uniform, tawny, protective colour--the colour of an old dead leaf. It also possessed a protective habit common to most grasshoppers, of embracing a slender vertical stem with its four fine front legs, and moving cunningly round so as to keep the stem always in front of it to screen itself from sight. Only other grasshoppers are silent when alarmed, and the silence and masking action are related, and together prevent the insect from being detected. But this particular species, or race, or colony, living on the sides of the isolated sierra, had acquired a contrary habit, resembling a habit of gregarious birds and mammals. For this informing sound (unless it mimicked some warning-sound, as of a rattlesnake, which it didn't) could not possibly be beneficial to individuals living alone, as grasshoppers generally do, but, on the contrary, only detrimental; and such a habit was therefore purely for the public good, and could only have arisen in a species that always lived in communities.

On another occasion, in the middle of the hot season, I was travelling alone across-country in a locality which was new to me, a few leagues east of La Plata River, in its widest part. About eleven o'clock in the morning I came to a low-lying level plain where the close-cropped grass was vivid green, although elsewhere all over the country the vegeta-

tion was scorched and dead, and dry as ashes. The ground being so favourable, I crossed this low plain at a swinging gallop, and in about thirty minutes' time. In that half-hour I saw a vast number of snakes, all of one kind, and a species new to me; but my anxiety to reach my destination before the oppressive heat of the afternoon made me hurry on. So numerous were the snakes in that green place that frequently I had as many as a dozen in sight at one time. It looked to me like a coronelía--harmless colubrine snakes--but was more than twice as large as either of the two species of that genus I was already familiar with. In size they varied greatly, ranging from two to fully five feet in length, and the colour was dull yellow or tan, slightly lined and mottled with shades of brown. Among dead or partially withered grass and herbage they would have been undistinguishable at even a very short distance, but on the vivid green turf they were strangely conspicuous, some being plainly visible forty or fifty yards away; and not one was seen coiled up. They were all lying motionless, stretched out full length, and looking like dark yellow or tan-coloured ribbons, thrown on to the grass. It was most unusual to see so many snakes together, although not surprising in the circumstances. The December heats had dried up all the water-courses and killed the vegetation, and made the earth hard and harsh as burnt bricks; and at such times snakes, especially the more active non-venomous kinds, will travel long distances, in their slow way, in search of water. Those I saw during my ride had probably been attracted by the mois-

ture from a large area of country; and although there was no water, the soft fresh grass must have been grateful to them. Snakes are seen coiled up when they are at home; when travelling and far afield, they lie as a rule extended full length, even when resting--and they are generally resting. Pausing at length, before quitting this green plain, to give my horse a minute's rest, I got off and approached a large snake; but when I was quite twelve yards from it, it lifted its head, and, turning deliberately round, came rather swiftly at me. I retreated, and it followed, until, springing on to my horse, I left it, greatly surprised at its action, and beginning to think that it must be venomous. As I rode on the feeling of surprise increased, conquering haste; and in the end, seeing more snakes, I dismounted and approached the largest, when exactly the same thing occurred again, the snake rousing itself and coming angrily at me when I was still (considering the dull lethargic character of the deadliest kinds) at an absurd distance from it. Again and again I repeated the experiment, with the same result. And at length I stunned one with a blow of my whip to examine its mouth, but found no poison-fangs in it.

I then resumed my journey, expecting to meet with more snakes of the same kind at my destination; but there were none, and very soon business called me to a distant place, and I never met with this species afterwards. But when I rode away from that green spot, and was once more on the higher, desolate, wind-swept plain surrounding it--a rustling sea of giant thistles, still erect, although

dead, and red as rust, and filling the hot blue sky with silvery down--it was with a very strange feeling. The change from the green and living to the dead and dry and dusty was so great! There seemed to be something mysterious, extra-natural, in that low level plain, so green and fresh and snaky, where my horse's hoofs had made no sound--a place where no man dwelt, and no cattle pastured, and no wild bird folded its wing. And the serpents there were not like others--the mechanical coiled-up thing we know, a mere bone-and-muscle man-trap, set by the elements, to spring and strike when trodden on: but these had a high intelligence, a lofty spirit, and were filled with a noble rage and astonishment that any other kind of creature, even a man, should venture there to disturb their sacred peace. It was a fancy, born of that sense of mystery which the unknown and the unusual in nature wakes in us--an obsolescent feeling that still links us to the savage. But the simple fact was wonderful enough, and that has been set down simply and apart from all fancies. If the reader happens not to be a naturalist, it is right to tell him that a naturalist cannot exaggerate consciously; and if he be capable of unconscious exaggeration, then ho is no naturalist. He should hasten "to join the innumerable caravan that moves" to the fantastic realms of romance. Looking at the simple fact scientifically, it was a case of mimicry--the harmless snake mimicking the fierce threatening gestures and actions proper to some deadly kind. Only with this difference: the venomous snake, of all deadly things in nature, is

378 The Naturalist in La Plata.

the slowest to resentment, the most reluctant to enter into a quarrel; whereas in this species angry demonstrations were made when the intruder was yet far off, and before he had shown any hostile intentions.

My last case--the last, that is, of the few I have selected--relates to a singular variation in the human species. On this occasion I was again travelling alone in a strange district on the southern frontier of Buenos Ayres. On a bitterly cold midwinter day, shortly before noon, I arrived, stiff and tired, at one of those pilgrims' rests on the pampas--a wayside pulpería, or public house, where the traveller can procure anything he may require or desire, from a tumbler of Brazilian rum to make glad his heart, to a poncho, or cloak of blue cloth with fluffy scarlet lining, to keep him warm o' nights; and, to speed him on his way, a pair of cast-iron spurs weighing six pounds avoirdupois, with rowels eight inches in diameter, manufactured in this island for the use of barbarous men beyond the sea. The wretched mud-and-grass building was surrounded by a foss crossed by a plank drawbridge; outside of the enclosure twelve or fourteen saddled horses were standing, and from the loud noise of talk and laughter in the bar I conjectured that a goodly company of rough frontiersmen were already making merry at that early hour. It was necessary for me to go in among them to see the proprietor of the place and ask permission to visit his kitchen in order to make myself a "tin of coffee," that being the refreshment I felt inclined for. When I went in and made my salutation, one man

wheeled round square before me, stared straight into my oyes, and in an exceedingly high-pitched reedy or screechy voice and a sing-song tone returned my "good morning," and bade me call for the liquid I loved best at his expense. I declined with thanks, and in accordance with gaucho etiquette added that I was prepared to pay for his liquor. It was then for him to say that he had already been served and so let the matter drop, but he did not do so: he screamed out in his wild animal voice that he would take gin. I paid for his drink, and would, I think, have felt greatly surprised at his strange insolent behaviour, so unlike that of the usually courteous gaucho, but this thing affected me not at all, so profoundly had his singular appearance and voice impressed me; and for the rest of the time I remained in the place I continued to watch him narrowly. Professor Huxley has somewhere said, "A variation frequently occurs, but those who notice it take no care about noting down the particulars." That is not a failing of mine, and this is what I noted down while the man's appearance was still fresh in memory. He was about five feet eleven inches in height--very tall for a gaucho--straight and athletic, with exceedingly broad shoulders, which made his round head look small; long arms and huge hands. The round flat face, coarse black hair, swarthy reddish colour, and smooth hairless cheeks seemed to show that he had more Indian than Spanish blood in him, while his round black eyes were even more like those of a rapacious animal in expression than in the pure-blooded Indian. He also had the Indian or

half-breed's moustache, when that natural ornament is permitted to grow, and which is composed of thick bristles standing out like a cat's whiskers. The mouth was the marvellous feature, for it was twice the size of an average mouth, and the two lips were alike in thickness. This mouth did not smile, but snarled, both when he spoke and when he should have smiled; and when he snarled the wliolo of his teeth and a part of the gums were displayed. The teeth were not as in other human beings--incisors, canines, and molars: they were all exactly alike, above and below, each tooth a gleaming white triangle, broad at the gum where it touched its companion teeth, and with a point sharp as the sharpest-pointed dagger. They were like the teeth of a shark or crocodile. I noticed that when he showed them, which was very often, they were not set together as in dogs, weasels, and other savage snarling animals, but apart, showing the whole terrible serration in the huge red mouth.

After getting his gin he joined in the boisterous conversation with the others, and this gave me an opportunity of studying his face for several minutes, all the time with a curious feeling that I had put myself into a cage with a savage animal of horrible aspect, whose instincts were utterly unknown to me, and were probably not very pleasant. It was interesting to note that whenever one of the others addressed him directly, or turned to him when speaking, it was with a curious expression, not of fear, but partly amusement and partly something else which I could not fathom. Now, one might think that this was natural enough purely on account of

Seen and Lost. 381

the man's extraordinary appearance. I do not think that a sufficient explanation; for however strange a man's appearance may be, his intimate friends and associates soon lose all sense of wonder at his strangeness, and even forget that he is unlike others. My belief is that this curiosity, or whatever it was they showed in their faces, was due to something in his character--a mental strangeness, showing itself at unexpected times, and which might flash, out at any moment to amuse or astonish them. There was certainly a correspondence between the snarling action of the mouth and the dangerous form of the teeth, perfect as that in any snarling animal; and such animals, it should be remembered, snarl not only when angry and threatening, but in their playful moods as well. Other and more important correspondences or correlations might have existed; and the voice was certainly unlike any human voice I have ever heard, whether in white, red, or black man. But the time I had for observation was short, the conversation revealed nothing further, and by-and-by I went away in search of the odorous kitchen, where there would be hot water for coffee, or at all events cold water and a kettle, and materials for making a fire--to wit, bones of dead cattle, "buffalo chips," and rancid fat.

I have never been worried with the wish, or ambition to be a head-hunter in the Dyak sense, but on this one occasion I did wish that it had been possible, without violating any law, or doing anything to a fellow-creature which I should not like done to myself, to have obtained possession of this man's head, with its set of unique and terrible teeth. For

382 The Naturalist in La Plata.

how, in the name of Evolution, did he come by them, and by other physical peculiarities--the snarling habit and that high-pitched animal voice, for instance--which made him a being different from others--one separate and far apart? Was he, so admirably formed, so complete and well-balanced, merely a freak of nature, to use an old-fashioned phrase--a sport, or spontaneous individual variation--an experiment for a new human type, imagined by Nature in some past period, inconceivably long ago, but which she had only now, too late, found time to carry out? Or rather was he like that little hairy maiden exhibited not long ago in London, a reproduction of the past, the mystery called reversion--a something in the life of a species like memory in the life of an individual, the memory which suddenly brings back to the old man's mind the image of his childhood? For no dream-monster in human form ever appeared to me with so strange and terrible a face; and this was no dream but sober fact, for I saw and spoke with this man; and unless cold steel has given him his quietus, or his own horse has crushed him, or a mad bull sored him--all natural forms of death in that wild land--he is probably still living and in the prime of life, and perhaps at this very moment drinking gin. at some astonished traveller's expense at that very bar where I met him. The old Palaeolithic man, judging from the few remains we have of him, must have had an unspeakably savage and, to our way of thinking, repulsive and horrible aspect, with his villainous low receding forehead, broad nose, great projecting upper jaw, and retreat-

ing chin; to meet such a man face to face in Piccadilly would frighten a nervous person of the present time. But his teeth were not unlike our own, only very much larger and more powerful, and well adapted to their work of masticating the flesh, underdone and possibly raw, of mammoth and rhinoceros. If, then, this living man recalls a type of the past, it is of a remoter past, a more primitive man, the volume of whose history is missing from the geological record. To speculate on such a subject seems idle and useless; and when 1 coveted possession of that head it was not because I thought that it might lead to any fresh discovery. A lower motive inspired the feeling. I wished for it only that I might bring it over the sea, to drop it like a new apple of discord, suited to the spirit of the times, among the anthropologists and evolutionists generally of this old and learned world. Inscribed, of course, "To the most learned," but giving no locality and no particulars. I wished to do that for the pleasure--not a very noble kind of pleasure, I allow--of witnessing from some safe hiding-place the stupendous strife that would have ensued--a battle more furious, lasting and fatal to many a brave knight of biology, than was ever yet fought over any bone or bony fragment or fabric ever picked up, including the celebrated cranium of the Neanderthal.

THE PUMA, OR LION OF AMERICA.

THE following passage occurs in an article on "The Naturalist in La Plata," by the late Professor Piomanes, which appeared in the Nineteenth Century, May, 1893. After quoting the account of the puma's habits and character given in the book, the writer says:--"I have received corroboration touching all these points from a gentleman who, when walking alone and unarmed on the skirts of a forest, was greatly alarmed by a large puma coming out to meet him. Deeming it best not to stand, he advanced to meet the animal, which thereupon began to gambol around his feet and rub against his legs, after the manner of an affectionate cat. At first he thought these movements must have been preliminary to some peculiar mode of attack, and therefore he did not respond, but walked quietly on, until the puma suddenly desisted and re-entered the forest. This gentleman says that, until the publication of Mr. Hudson's book, he had always remained under the impression that that particular puma must have been insane."

MUSIC AND DANCING IN NATURE.

I have found among my papers the following mislaid note on the subject of sportive displays of mammalians, which should have been used on page 281, where the subject is briefly treated:--Most mammalians are comparatively silent and live on the ground, and not having the power to escape

easily, which birds have, and being more persecuted by man, they do not often disport themselves unrestrainedly in his presence; it is difficult to watch any wild animal without the watcher's presence being known or suspected. Nevertheless, their displays are not so rare as we might imagine. I have more than once detected species, with which I was, or imagined myself to be, well acquainted, disporting themselves in a manner that took me completely by surprise. While out tinamou shooting one day in autumn, near my own home in La Plata, I spied a troop of about a dozen weasels racing madly about over a vizcacha village--the mound and group of pit-like burrows inhabited by a community of vizcachas. These weasels were of the large common species, Galictis barbara, about the size of a cat; and were engaged in a pastime resembling a complicated dance, and so absorbed were they on that occasion that they took no notice of me when I walked up to within nine or ten yards of them, and stood still to watch the performance. They were all swiftly racing about and leaping over the pits, always doubling quickly back when the limit of the mound was reached, and although apparently carried away with excitement, and crossing each other's tracks at all angles, and this so rapidly and with so many changes of direction that I became confused when trying to keep any one animal in view, they never collided nor even came near enough to touch one another. The whole performance resembled, on a greatly magnified scale and without its beautiful smoothness and lightning swiftness, the fantastic dance of small black water-beetles, frequently seen on the surface of a pool or stream, during which the insects glide about in a limited area with such celerity as to appear like black curving lines traced by flying invisible pens; and as the lines everywhere cross and intersect, they form an intricate pattern on the surface, After watching the weasel dance for some minutes, I stepped up to the mound, whereupon the animals became alarmed and rushed pell-mell into the burrows, but only to reappear in a few seconds, thrusting up their long ebony-

black necks and flat grey-capped heads, snarling chattering at me, glaring with fierce, beady eyes.

THE STRANGE INSTINCTS OF CATTLE.

In November and December, 1893, a short correspondence appeared in the Field on the curious subject of "Dogs burying their dead." It arose through a letter from a Mr. Gould, of Albany, Western Australia, relating the following incident:--

A settler shot a bitch from a neighbouring estate that had formed the habit of coming on to his land to visit and play with his dog. The dog, finding his companion dead, was observed to dig a large hole in the ground, into which he dragged the carcase; but he did not cover it with earth. The writer wished to know if any reader of the Field had met with a similar case. Some notes, which I contributed in reply to this letter, bear on one of the subjects treated in the chapter on "strange instincts," namely, the instinct of social animals to protect and shield their fellows; and for this reason I have thought it best to reproduce them in this place.

I remember on one occasion watching at intervals, for an entire day, a large and very savage dog keeping watch over the body of a dead bitch that had been shot. He made no attempt to bury the dead animal, but he never left it. He was observed more than once trying to drag the body away, doubtless with the intention of hiding it; not succeeding in these attempts, he settled down by its side again, although it was evident that he was suffering greatly from thirst and heat. It was at last only with the greatest trouble that the people of the house succeeded in getting the body away and burying it out of his sight.

Another instance, more to the point, occurred at my own house on the pampas, and I was one of several persons who witnessed it. A small, red, long-haired bitch--a variety of

Appendix. 387

the common native cur--gave birth to four or five pups. A peon was told to destroy them, and, waiting until the bitch was out of sight, he carried them off to the end of the orchard, some 400 or 500 yards from the house, and threw them into a pool of water which was only two to three feet deep. The bitch passed the rest of the day in rushing frantically about, searching for her young, and in the evening, a little after dark, actually succeeded in finding them, although they were lying at the bottom of the pool. She got them all out, and carried them, one by one, to another part of the grounds, where she passed the night with them, uttering at intervals the most piercing cries. In the morning she carried them to still another spot, where there was a soft mould, and then dug a hole large and deep enough to bury them all, covering them over with the loose earth. Her task done, she returned to the house to sleep all day, but when night came again the whole piteous performance was repeated: the pups were dug up, and she passed the long, piercingly cold night--for it was in the depth of winter--trying to keep them warm, and uttering, as before, distressing cries. Yet a third time the whole thing was repeated; but after the third night, when the dog came home to sleep, the dead pups were taken out of the ground and buried at a distance.

Such an action as this strikes one with astonishment only because we have the custom of burying our dead, and are too ready at all times to regard the dog as human-like. But the explanation of the action in this case is to be found in the familiar fact that very many animals, including the dog, have the habit or instinct of burying or concealing the thing they wish to leave in safety. Thus, the dog buries the bone it does not want to eat, and when hungry digs it up again. When a dog buries or hides the dead body of the she dog it was attached to, or the she dog buries her dead young, it is with the same motive--namely, to conceal the animal that cannot be roused, and that it would not be safe to leave exposed.

388 Appendix.

It is plain to all who observe their actions that the lower animals have no comprehension of death. In the case of two animals that are accustomed to play or to be much together, if one dies, or is killed, and its body left, the other will come to sniff at, touch, and at last try to rouse it; but finding all attempts vain, it will at length go away to seek companionship elsewhere. In cases where the attachment is much stronger, the dead body may be watched over for an indefinite period. A brother of mine once related to me a very pathetic incident which occurred at an estancia on the pampas where he was staying. A large portion of the land was a low, level, marshy plain, partly overgrown with reeds and rushes; and one day, in this wilderness, a little boy of eight or nine, from the estancia, lost himself. A small dog, his invariable attendant, had gone out with him, but did not return. Seven days later the poor boy was found, at a great distance from the house, lying on the grass, where he had died of exhaustion. The dog was lying coiled up at his side, and appeared to be sleeping; but, when spoken to, he did not stir, and was presently found to be dead too. The dog could have gone back at any moment to the estancia, but his instinct of attachment overcame all others; he kept guard over his little master, who slept so soundly and so long, until he, too, slept in the same way.

A still more remarkable case of this kind was given in one of my books, of a gaucho, accompanied by his dog, who was chased and overtaken by a troop of soldiers during one of the civil wars in Uruguay. Suspecting him of being a spy, or, at all events, an enemy, his captors cut his throat, then rode away, calling to the dog to follow them; but the animal refused to leave his dead master's side. Returning to the spot a few days later, they saw the body of the man they had killed surrounded by a large number of vultures, which the dog, in a frenzy of excitement, was occupied in keeping at a respectable distance. It was observed that the dog, after making one of his sallies, driving the birds away with furious barkings, would set out at a run to a small stream

Appendix. 389

not far from the spot; but when half way to it he would look back, and, seeing the vultures advancing once more to the corpse, would rush back to protect it. The soldiers watched him for some time with great interest, and once more they tried in vain to get him to follow them. Two days afterwards they revisited the spot, to find the dog lying dead by the side of his dead master. I had this story from the lips of one of the witnesses.

In all such cases, whether the dog watches over, conceals, or buries a dead body, he is doubtless moved by the same instinct which leads him to safeguard the animal he is attached to--another dog or his human master. But, as the dead animal is past help, it is, of course, a blunder of the instinct; and the blunder must be of very much less frequent occurrence among wild than among domestic animals. In a state of nature, when a gregarious animal dies, he dies, as a rule, alone; his body is not seen by his former companions, and he is not missed. When he dies by violence--which is the common fate--the body is carried off or devoured by the killer. This being the usual order, there is no instinct, except in a very few species, relating to the disposal of the dead among mammals and other vertebrates, such as is found in ants and other social insects. There are a few mammalians that live together in small communities, in a habitation made to last for many generations, in which such an instinct would appear necessary, and it accordingly exists, but is very imperfect. This is the case with the vizcacha, the large rodent of the pampas, which lives with its fellows, to the number of twenty or thirty, in a cluster of huge burrows. When a vizcacha dies in a burrow, the body is dragged out and thrown on to the mound among the mass of rubbish collected on it--but not until he has been dead a long time, and there is nothing left of him but the dry bones held together by the skin. In that condition the other members of the community probably cease to look on him as one of their companions who has fallen into a long sleep; he is no more than so much rubbish, which must be cleared out

390 Appendix.

of an old disused burrow. Probably the beaver possesses some rude instinct similar to that of the vizcacha.

Apropos of animals burying their treasures (or connections) for safety, it is worth mentioning that the skunk of the pampas occasionally buries her young in the kennel, when hunger compels her to go out foraging. I had often heard of this habit of the female skunk from the gauchos, and one day had the rare good fortune to witness an animal engaged in obliterating her own kennel. The senses of the skunk are so defective that one is able at times to approach very near to without alarming them. In this instance I sat on my horse at a distance of twenty yards, and watched the animal at work, drawing in the loose earth with her fore feet until the entrance to the kennel was filled up to within three inches of the surface; then, dropping into the shallow cavity, she pressed the loose mould down with her nose. Her task finished, she trotted away, and the hollow in the soil, when I examined it closely, looked only like the mouth of an ancient choked-up burrow. The young inhabit a circular chamber, lined with fine dry grass, at the end of a narrow passage from 3 ft. to 5 ft. long, and no doubt have air enough to serve them until their parent returns; but I believe the skunk only buries her young when they are very small.
