And no coaxing could persuade it to do so unless it felt so inclined. The same cat also, whenever it wanted to go out, would come into the sitting-room, and make a peculiar noise to attractattention: failing that mode being successful, it would pull one's dress with its claw and then having succeeded in attracting the desired attention, it would walk to the street door and stop there, making the same cry until let out.

Coming now to cases indicative of reason in cats, Mr. John Martin, writing from St. Clement's, Oxford, informs me: 'I have a cat which a short time ago had kittens, and from some cause or other her milk failed. My housekeeper saw her carrying a piece of bread to them.' The process of reasoning here is obvious.
Mr. Bidie, writing from the Government Museum of Madras to 'Nature' (vol. xx., p. 96), relates this instance of reasoning in a cat:—
In 1877 I was absent from Madras for two months, and left in my quarters three cats, one of which, an English tabby, was a very gentle and affectionate creature. During my absence the quarters were occupied by two young gentlemen, who delighted in teasing and frightening the cats. About a week before my return the English cat had kittens, which she carefully concealed behind bookshelves in the library. On the morning of my return I saw the cat, and patted her as usual, and then left the house for about an hour. On returning to dress I found that the kittens were located in a corner of my dressing-room, where previous broods had been deposited and nursed. On questioning the servant as to how they came there, he at once replied, 'Sir, the old cat taking one by one in her mouth, brought them here.' In other words, the mother had carried them one by one in her mouth from the library to the dressing-room, where they lay quite exposed. I do not think I have heard of a more remarkable instance of reasoning and affectionate confidence in an animal, and I need hardly say that the latter manifestation gave me great pleasure. The train of reasoning seems to have been as follows: 'Now that my master has returned there is no risk of the kittens being injured by the two young savages in the house, so I will take them out for my protector to see and admire, and keep them in the corner in which all my former pets have been nursed in safety.'

Dr. Bannister writes me from Chicago, of a cat belonging to his friend the late Mr. Meek, the palæontologist, who drew my correspondent's attention to the fact:—
He had fixed upright on his table a small looking-glass, from which he used to draw objects from nature, reversed on wood. The cat seeing her image in this glass made several attempts to investigate it, striking at it, &c. Then coming apparently to the conclusion that there was something between her and the other animal, she very slily and cautiously approached it, keeping her eye on it all the while, and struck her paw around behind the mirror, becoming seemingly much surprised at finding nothing there. This was done repeatedly, until she was at last convinced that it was beyond her comprehension, or she lost interest in the matter.

Mr. T. B. Groves communicates an almost precisely similar observation to 'Nature' (vol. xx., p. 291), of a cat which, on first seeing his own reflection in a mirror, tried to fight it. Meeting with resistance from the glass, the cat next ran behind the mirror. Not finding the object of his search, he again came to the front, and while keeping his eyes deliberately fixed on the image, felt round the edge of the glass with one paw, whilst with his head twisted round to the front he assured himself of the persistence of the reflection. He never afterwards condescended to notice a mirror.
The following is communicated to me by a correspondent whose name I cannot obtain permission to publish. I am sure, however, that it is communicated in good faith, and the incident can scarcely be supposed to have been due to accident. After describing the cat and the parrot in their amiable relationship, my correspondent proceeds:—
One evening there was no one in the kitchen. Cook had gone upstairs, and left a bowl full of dough to rise by the fire. Shortly after, the cat rushed up after her, mewing, and making what signs she could for her to go down; then she jumped up and seized her apron, and tried to drag her down. As she was in such a state of excitement cook went, and found 'Polly' shrieking, calling out, flapping her wings and struggling violently, 'up to her knees' in dough, and stuck quite fast.No doubt if she had not been rescued she would have sunk in the morass and been smothered.

I shall here introduce two or three cases to show the ingenious devices to which clever cats will resort for the purpose of capturing prey.
Mr. James Hutchings writes in 'Nature' (vol. xii., p. 330) an account of an old tom cat using a young bird, which had fallen out of its nest, as a decoy for the old birds. The cat touched the young bird with his paw when it ceased to flutter and cry, in order that, by thus making it display its terror, the old cock bird, which was all the while flying about in great consternation, might be induced to approach near enough to be caught. Many times the cock bird did so, and the cat made numerous attempts to catch it, but without success. All the while a kitten had to be kept from killing the young bird. As this scene continued for a long time—in fact, till terminated by Mr. Hutchings—and as there does not appear to have been any opportunity for errors of observation, I think the case worth recording.
The following case is communicated to me by Mr. James G. Stevens, of St. Stephen, New Brunswick:—
Looking out on the garden in front of my residence, I observed a robin alight on a small tree: it was midwinter, the ground covered with about a foot oflightsnow. A cat came stealthily along, with difficulty making her way through the snow until within about three feet of the tree where the bird was; the robin was sluggishly resting on a twig distant three feet from the ground or surface of snow; the cat could not well, owing to the softness of the snow, venture to make a spring. She crouched down and at first gently stirred herself, evidently with the purpose of causing the bird to move. The first attempt failed. She again more actively stirred herself by a shaking motion. She again failed, when she stirred herself vigorously again and started the bird, which flew about fifty feet away, and alighted on a small low bush on thenorthernside of aclose-boardedfence. The cat keenly watched the flight and the alighting of the bird; as quickly as she could cross through the snow, she thentook a circuit of about one hundred feet, watching the place where the bird was all the while, and covering her march by makingavailable every bush to hide her. When out of range of vision of the bird she more actively made for the fence, leaped over it, came up on thesouthernside of it, and jumped on it, calculating her distance so accurately that she came within a foot of the bush where the bird was, and at once sprung. She missed her prey, but I thought she proved herself a cunning hunter. If this case is worth relating you may use the nameof Judge Stevens, of St. Stephen, New Brunswick, as a witness to the same.

Again, I quote the following case communicated to 'Nature' by Dr. Frost, because, although it shows an almost incredible amount of far-sighted stratagem, I cannot on the one hand see much room for mal-observation, and on the other hand it is, as I shall show, to some extent corroborated by an independent observation of my friend Dr. Klein, and another correspondent:—
Our servants have been accustomed during the late frost to throw the crumbs remaining from the breakfast-table to the birds, and I have several times noticed that our cat used to wait there in ambush in the expectation of obtaining a hearty meal from one or two of the assembled birds. Now, so far, this circumstance in itself is not an 'example of abstract reasoning.' But to continue. For the last few days this practice of feeding the birds has been left off. The cat, however, with an almost incredible amount of forethought, was observed by myself, together with two other members of the household, to scatter crumbs on the grass with the obvious intention of enticing the birds.[256]

The cat, however, with an almost incredible amount of forethought, was observed by myself, together with two other members of the household, to scatter crumbs on the grass with the obvious intention of enticing the birds.[256]
Although this account, as I have said, borders on the incredible, I have allowed it to pass, because up to a certain point it is, as I have also said, corroborated by an observation communicated to me by my friend Dr. Klein, F.R.S.
Dr. Klein satisfied himself that the cat he observed had established a definite association between crumbs already sprinkled on the garden walk, and sparrows coming to eat them; for as soon as the crumbs were sprinkled on the walk, the cat used to conceal himself from the walk in a neighbouring shrubbery, there to await in ambush the coming of the birds. The latter, however, showed themselves more wide awake than the cat, for there was a wall running behind the shrubbery, from the top of which the birds could see the cat in his supposed concealment, and then a long line of sparrows used to wait watching the cat and the crumbs at the same time, but never venturing to fly down to the latter until the former, wearied with waiting, went away. In this case the reasoning observationof the cat—'crumbs attract birds, therefore I will wait for birds when crumbs are scattered'—was as complete as in the case of Dr. Frost's cat, but the reasoning in the latter case seems to have proceeded a stage further—'therefore I will scatter crumbs to attract birds.'
Now, in the face of the definite statement made by Dr. Frost, that his cat did advance to this further stage of reasoning, I have not felt justified in suppressing his remarkable observation. And, as lending still further credence to the account, I may quote the corroborative observation of another correspondent in 'Nature,' which is of value because forming an intermediate step between the intelligence displayed by Dr. Klein's cat and that displayed by Dr. Frost's. This correspondent says:—
A case somewhat similar to that mentioned by Dr. Frost, of a cat scattering crumbs, occurred here within my own knowledge. During the recent severe winter a friend was in the habit of throwing crumbs outside his bedroom window. The family have a fine black cat, which, seeing that the crumbs brought birds, would occasionally hide herself behind some shrubs, and when the birds came for their breakfast, would pounce out upon them with varying success. The crumbs had been laid out as usual one afternoon, but left untouched, and during the night a slight fall of snow occurred. On looking out next morning my friend observed puss busily engaged scratching away the snow. Curious to learn what she sought, he waited, and saw her take the crumbs up from the cleared space and lay them one by one after another on the snow. After doing this she retired behind the shrubs to wait further developments. This was repeated on two other occasions.[257]

After doing this she retired behind the shrubs to wait further developments. This was repeated on two other occasions.[257]
Taking, then, these three cases together, we have an ascending series in the grades of intelligence from that displayed by Dr. Klein's cat, which merely observed that crumbs attracted birds, through that of the cat which exposed the concealed crumbs for the purpose of attracting birds, to that of Dr. Frost's cat, which actually sprinkled the crumbs. Therefore, although, if the last-mentioned or most remarkable case had stood alone, I should not have felt justified in quoting it, as we find it thus led up to by other and independent observations, I do not feel that Ishould be justified in suppressing it. And, after all, regarded as an act of reason, the sprinkling of crumbs to attract birds does not involve ideas or inferences very much more abstruse or remote than those which are concerned in some of the other and better corroborated instances of the display of feline intelligence, which I shall now proceed to state.
In the understanding of mechanical appliances, cats attain to a higher level of intelligence than any other animals, except monkeys, and perhaps elephants. Doubtless it is not accidental that these three kinds of animals fall to be associated in this particular. The monkey in its hands, the elephant in its trunk, and the cat in its agile limbs provided with mobile claws, all possess instruments adapted to manipulation, with which no other organs in the brute creation can properly be compared, except the beak and toes of the parrot, where, as we have already seen, a similar correlation with intelligence may be traced. Probably, therefore, the higher aptitude which these animals display in their understanding of mechanical appliances is due to the reaction exerted upon their intelligence by these organs of manipulation. But, be this as it may, I am quite sure that, excepting only the monkey and elephant, the cat shows a higher intelligence of the special kind in question than any other animal, not forgetting even the dog. Thus, for instance, while I have only heard of one solitary case (communicated to me by a correspondent) of a dog which, without tuition, divined the use of a thumb-latch, so as to open a closed door by jumping upon the handle and depressing the thumb-piece, I have received some half-dozen instances of this display of intelligence on the part of cats. These instances are all such precise repetitions of one another, that I conclude the fact to be one of tolerably ordinary occurrence among cats, while it is certainly very rare among dogs. I may add that my own coachman once had a cat which, certainly without tuition, learnt thus to open a door that led into the stables from a yard into which looked some of the windows of the house. Standing at these windows when the cat did not see me, I have many times witnessed hermodus operandi. Walking up to the door with a most matter-of-course kind of air, she used to spring at the half-hoop handle just below the thumb-latch. Holding on to the bottom of this half-hoop with one fore-paw, she then raised the other to the thumb-piece, and while depressing the latter, finally with her hind legs scratched and pushed the doorposts so as to open the door. Precisely similar movements are described by my correspondents as having been witnessed by them.
Of course in all such cases the cats must have previously observed that the doors are opened by persons placing their hands upon the handles, and, having observed this, the animals forthwith act by what may be strictly termed rational imitation. But it should be observed that the process as a whole is something more than imitative. For not only would observation alone be scarcely enough (within any limits of thoughtful reflection that it would be reasonable to ascribe to an animal) to enable a cat upon the ground to distinguish that the essential part of the process as performed by the human hand consists, not in grasping the handle, but in depressing the latch; but the cat certainly never saw any one, after having depressed the latch, pushing the doorposts with his legs; and that this pushing action is due to an originally deliberate intention of opening the door, and not to having accidentally found this action to assist the process, is shown by one of the cases communicated to me (by Mr. Henry A. Gaphaus); for in this case, my correspondent says, 'the door was not a loose-fitting one by any means, and I was surprised that by the force of one hind leg she should have been able to push it open after unlatching it.' Hence we can only conclude that the cats in such cases have a very definite idea as to the mechanical properties of a door; they know that to make it open, even when unlatched, it requires to bepushed—a very different thing from trying to imitate any particular action which they may see to be performed for the same purpose by man. The whole psychological process, therefore, implied by the fact of a cat opening a door in this way is really most complex. First the animal must have observedthat the door is opened by the hand grasping the handle and moving the latch. Next she must reason, by 'the logic of feelings'—If a hand can do it, why not a paw? Then, strongly moved by this idea, she makes the first trial. The steps which follow have not been observed, so we cannot certainly say whether she learns by a succession of trials that depression of the thumb-piece constitutes the essential part of the process, or, perhaps more probably, that her initial observations supplied her with the idea of clicking the thumb-piece. But, however this may be, it is certain that the pushing with the hind feet after depressing the latch must be due to adaptive reasoning unassisted by observation; and only by the concerted action of all her limbs in the performance of a highly complex and most unnatural movement is her final purpose attained.
Again, several very similar cases are communicated to me of cats spontaneously, or without tuition, learning to knock knockers and ring bells. Of course in both cases the animals must have observed the use to which knockers and bells are put, and when desiring a door to be opened, employ these signals for the purpose. It betokens no small amount of observation and reasoning in a cat to jump at a knocker with the expectation of thereby summoning a servant to open the door—especially as in some of the cases the jump is not a random jump at the knocker, but a deliberate and complex action, having for its purposes the raising and letting fall of the knocker. For instance, Mr. Belshaw, writing to 'Nature' (vol. xix., p. 659), says:—
I was sitting in one of the rooms, the first evening there, and hearing a loud knock at the front door was told not to heed it, as it was only this kitten asking admittance. Not believing it, I watched for myself, and very soon saw the kitten jump onto the door, hang on by one leg, and put the other fore-paw right through the knocker and rap twice.

Not believing it, I watched for myself, and very soon saw the kitten jump onto the door, hang on by one leg, and put the other fore-paw right through the knocker and rap twice.
In such cases the action closely resembles that of opening thumb-latches, but clearly is performed with the purpose of summoning some one else to open the door. Wonderful, however, as these cases of summoningby knockers undoubtedly are, I think they are surpassed by other cases in which the instrument used is the bell. For here it is not merely that cats perfectly well understand the use of bells as calls,[258]but I have one or two cases of cats jumping at bell-wirespassing from outside intohouses the doors of which the cats desired to be opened.[259]My informants tell me that they do not know how these cats, from any process of observation, can have surmised that pulling the wire in an exposed part of its length would have the effect of ringing the bell; for they can never have observed any one pulling the wires. I can only suggest that in these cases the animals must have observed that when the bells were rung the wires moved, and that the doors were afterwards opened; then a process of inference must have led them to try whether jumping at the wires would produce the same effects. But even this, which is the simplest explanation possible, implies powers of observation scarcely less remarkable than the process of reasoning to which they gave rise.
As further instances corroborating the fact that both these faculties are developed in cats to a wonderful degree, I may add the following. Couch ('Illustrations of Instinct,' p. 196) gives a case within his own knowledge of a cat which, in order to get at milk kept in a locked cupboard, used to unlock the door by seating herself on an adjoining table, and 'repeatedly patting on the bow of the key with her paw, when with a slight pull on the door' she was able to open it; the lock was old, and the key turned in it 'on a very slight impulse.'
As a still further instance of the high appreciation of mechanical appliances to which cats attain, I shall quote an extract from a paper by Mr. Otto, which will have been read at the Linnean Society before this work is published.After describing the case of a cat opening a thumb-latch in the same way as those already mentioned, this writer proceeds:—
At Parara, the residence of Parker Bowman, Esq., a full-grown cat was one day accidentally locked up in a room without any other outlet than a small window, moving on hinges, and kept shut by means of a swivel. Not long afterwards the window was found open and the cat gone. This having happened several times, it was at last found that the cat jumped upon the window-sill, placed her fore-paws as high as she could reach against the side, deliberately reached with one over to the swivel, moved it from its horizontal to a perpendicular position, and then, leaning with her whole weight against the window, swung it open and escaped.

To give only one other instance of high reasoning power in this animal, Mr. W. Brown, writing from Greenock to 'Nature' (vol. xxi., p. 397), gives a remarkable story of a cat, the facts in which do not seem to have admitted of mal-observation. While a paraffine lamp was being trimmed, some of the oil fell upon the back of the cat, and was afterwards ignited by a cinder falling upon it from the fire. The cat with her back 'in a blaze, in an instant made for the door (which happened to be open) and sped up the street about 100 yards,' where she plunged into the village watering-trough, and extinguished the flame. 'The trough had eight or nine inches of water, and puss was in the habit of seeing the fire put out with water every night.' The latter point is important, as it shows the data of observation on which the animal reasoned.
FOXES, WOLVES, JACKALS, ETC.
Thegeneral psychology of these animals is, of course, very much the same as that of the dog; but, from never having been submitted to the influences of domestication, their mental qualities present a sufficient number of differences from those of the dog to require another chapter for their consideration.
If we could subtract from the domestic dog all the emotions arising from his prolonged companionship with man, and at the same time intensify the emotions of self-reliance, rapacity, &c., we should get the emotional character now presented by the wolves and jackals. It is interesting to note that this genetic similarity of emotional character extends to what may be termed idiosyncratic details in cases where it has not been interfered with by human agency. Thus the peculiar, weird, and unaccountable class of emotions which cause wolves to bay at the moon has been propagated unchanged to our domestic dogs.
The intelligence of the fox is proverbial; but as I have not received many original observations on this head, I shall merely refer to some of the best authenticated observations already published, and shall begin with the instance narrated by Mr. St. John in his 'Wild Sports of the Highlands':—
When living in Ross-shire I went out one morning in July, before daybreak, to endeavour to shoot a stag, which had been complained of very much by an adjoining farmer, as having done great damage to his crops. Just after it was daylight I saw a large fox coming quietly along the edge of the plantationin which I was concealed; he looked with great care over the turf wall into the field, and seemed to long to get hold of some hares that were feeding in it, but apparently knew that he had no chance of catching one by dint of running; after considering a short time he seemed to have formed his plans, and having examined the different gaps in the wall by which the hares might be supposed to go in and out, he fixed upon the one that seemed the most frequented, and laid himself down close to it in an attitude like a cat watching a mouse. Cunning as he was, he was too intent on his own hunting to be aware that I was within twenty yards of him with a loaded rifle, and able to watch every movement that he made. I was much amazed to see the fellow so completely outwitted, and kept my rifle ready to shoot him if he found me out and attempted to escape. In the meantime I watched all his plans. He first with great silence and care scraped a small hollow in the ground, throwing up the sand as a kind of screen between his hiding-place and the hares' mews; every now and then, however, he stopped to listen, and sometimes to take a most cautious look into the field; when he had done this he laid himself down in a convenient position for springing upon his prey, and remained perfectly motionless with the exception of an occasional reconnoitre of the feeding hares. When the sun began to rise, they came one by one from the field to the cover of the plantation; three had already come in without passing by his ambush; one of them came within twenty yards of him, but he made no movement beyond crouching still more closely to the ground. Presently two came directly towards him; though he did not venture to look up, I saw by an involuntary motion of his ears that those quick organs had already warned him of their approach: the two hares came through the gap together, and the fox, springing with the quickness of lightning, caught one and killed her immediately; he then lifted up his booty and was carrying it off like a retriever, when my rifle-ball stopped his course by passing through his back-bone, and I went up and despatched him.

Numberless instances are on record showing the remarkable cunning of foxes in procuring bait from traps without allowing themselves to be caught. These cases are so numerous, and all display so much the same quality of intelligence, that it is impossible to doubt so great a concurrence of testimony. I shall only give two or three specific cases, to show the kind of intelligence that is inquestion. It will be observed that it is much the same as that which is displayed under similar circumstances by rats and wolverines, in which animals we have already considered it. In all these cases the intelligence displayed must justly be deemed to be of a very remarkable order. For, inasmuch as traps are not things to be met with in nature, hereditary experience cannot be supposed to have played any part in the formation of special instincts to avoid the dangers arising from traps, and therefore the astonishing devices by which these dangers are avoided can only be attributed to observation, coupled with intelligent investigation of a remarkably high character.
I extract the following from Couch's 'Illustrations of Instinct' (p. 175):—
Whenever a cat is tempted by the bait, and caught in a fox-trap, Reynard is at hand to devour the bait and the cat too, and fearlessly approaches an instrument which the fox must know cannotthendo it any harm. Let us compare with this boldness the incredible caution with which the animal proceeds when tempted by the bait in asettrap. Dietrich aus dem Winkell had once the good fortune of observing, on a winter evening, a fox which for many preceding days had been allured with loop baits, and as often as it ate one it sat comfortably down, wagging its brush. The nearer it approached the trap, the longer did it hesitate to take the baits, and the oftener did it make the tour round the catching-place. When arrived near the trap it squatted down, and eyed the bait for ten minutes at least; whereupon it ran three or four times round the trap, then it stretched out one of its fore-paws after the bait, but did not touch it; again a pause, during which the fox stared immovably at the bait. At last, as if in despair, the animal made a rush and was caught by the neck. (Mag. Nat. Hist., N. S., vol. i., p. 512.)
Whenever a cat is tempted by the bait, and caught in a fox-trap, Reynard is at hand to devour the bait and the cat too, and fearlessly approaches an instrument which the fox must know cannotthendo it any harm. Let us compare with this boldness the incredible caution with which the animal proceeds when tempted by the bait in asettrap.

In 'Nature,' vol. xxi., p. 132, Mr. Crehore, writing from Boston, says:—
Some years since, while hunting in Northern Michigan, I tried with the aid of a professional trapper to entrap a fox who made nightly visits to a spot where the entrails of a deer had been thrown. Although we tried every expedient that suggested itself to us we were unsuccessful, and, what seemed verysingular, we always found the trap sprung. My companion insisted that the animal dug beneath it, and putting his paw beneath the jaw, pushed down the pan with safety to himself; but though the appearance seemed to confirm it, I could hardly credit his explanation. This year, in another locality of the same region, an old and experienced trapper assured me of its correctness, and said in confirmation that he had several times caught them, after they had made two or three successful attempts to spring the trap, by the simple expedient of setting it upside down, when of course the act of undermining and touching the pan would bring the paw within the grasp of the jaws.

In connection with traps, my friend Dr. Rae has communicated to me a highly remarkable instance of the display of reason on the part of the Arctic foxes. I have previously published the facts in my lecture before the British Association in 1879, and therefore shall here quote them from it:—
Desiring to obtain some Arctic foxes, Dr. Rae set various kinds of traps; but as the foxes knew these traps from previous experience, he was unsuccessful. Accordingly he set a kind of trap with which the foxes in that part of the country were not acquainted. This consisted of a loaded gun set upon a stand pointing at the bait. A string connected the trigger of the gun with the bait, so that when the fox seized the bait he discharged the gun, and thus committed suicide. In this arrangement the gun was separated from the bait by a distance of about 30 yards, and the string which connected the trigger with the bait was concealed throughout nearly its whole distance in the snow. The gun-trap thus set was successful in killing one fox, but never in killing a second; for the foxes afterwards adopted either of two devices whereby to secure the bait without injuring themselves. One of these devices was to bite through the string at its exposed part near the trigger, and the other device was to burrow up to the bait through the snow at right angles to the line of fire, so that, although in this way they discharged the gun, they escaped with perhaps only a pellet or two in the nose. Now both of these devices exhibited a wonderful degree of what I think must fairly be called power of reasoning. I have carefully interrogated Dr. Rae on all the circumstances of the case, and he tells me that in that part of the world traps are never set with strings; so that there can have been no special association in the foxes' minds between strings and traps. Moreover, after the death of fox No. 1, the track onthe snow showed that fox No. 2, notwithstanding the temptation offered by the bait, had expended a great deal of scientific observation on the gun before he undertook to sever the cord. Lastly, with regard to burrowing at right angles to the line of fire, Dr. Rae justly deemed this so extraordinary a circumstance, that he repeated the experiment a number of times, in order to satisfy himself that the direction of the burrowing was really to be attributed to thought, and not to chance.[260]

Dr. Rae also informs me with, regard to wolves, that 'they have been frequently known to take the bait from a gun without injury to themselves, by first cutting the line of communication between the two.'[261]He adds:—
I may also mention what I have been told, although I have never had an opportunity of seeing it, that wolves watch the fishermen who set lines in deep water for trout, through holes in the ice on Lake Superior, and very soon after the man has left, the wolf goes up to the place, takes hold of the stick which is placed across the hole and attached to the line, trots off with it along the ice until the bait is brought to the surface, then returns and eats the bait and the fish, if any happens to be on the hook. The trout of Lake Superior are very large, and the baits are of a size in proportion.

Mr. Murray Browne, Inspector of the Local Government Board, writes to me from Whitehall as follows:—
I once, at the Devil's Glen, Wicklow, found a fox fast in a trap by the foot. We did not like to touch him, but got sticks and poked at the trap till we got it open. The process took ten minutes or a quarter-hour. When first we came up the fox strained to get free, and looked frightfully savage; but we had not poked at the trap more than a very short time before the whole expression of his face changed, he lay perfectly quiet (though we must at times have hurt him); and when at last we had got the trap completely off his foot, he still lay quiet,and looked calmly at us, as if he knew we were friends. In fact, we had some little difficulty in getting him to move away, which he did readily enough when he chose. Was not this a case of reason and good senseoverpoweringnatural instinct?

Couch says ('Illustrations of Instinct,' p. 178): 'Derham quotes Olaus in his account of Norway as having himself witnessed the fact of a fox dropping his tail among the rocks on the sea-shore to catch the crabs below, and hauling up and devouring such as laid hold of it.'
Under the present heading I must not omit to refer to an interesting class of instincts which are manifested by those species of the genusCanis, whose custom it is to hunt in packs. The instincts to which I refer are those which lead to a combination among different members of the same pack for the capture of prey by stratagem. These instincts, which no doubt arose and are now maintained by intelligent adaptation to the requirements of the chase, I shall call 'collective instincts.' Thus Sir E. Tennent writes:—
At dusk, and after nightfall, a pack of jackals, having watched a hare or a small deer take refuge in one of these retreats, immediately surrounded it on all sides; and having stationed a few to watch the path by which the game entered, the leader commences the attack by raising the cry peculiar to their race, and which resembles the sound 'okkay' loudly and rapidly repeated. The whole party then rush into the jungle and drive out the victim, which generally falls into the ambush previously laid to entrap it.A native gentleman, who had favourable opportunities of observing the movements of these animals, informed me that when a jackal has brought down his game and killed it, his first impulse is to hide it in the nearest jungle, whence he issues with an air of easy indifference to observe whether anything more powerful than himself may be at hand, from which he might encounter the risk of being despoiled of his capture. If the coast be clear he returns to the concealed carcass and carries it away, followed by his companions. But if a man be in sight, or any other animal to be avoided, my informant has seen the jackal seize a cocoa-nut husk in his mouth, or any similar substance, and fly at full speed, as if eager to carry off his pretendedprize, returning for the real booty at some more convenient season.[262]

Again, Jesse records the following display of the same instinct by the fox, as having been communicated to him by a friend on whose veracity he could rely:—
Part of this rocky ground was on the side of a very high hill, which was not accessible for a sportsman, and from which both hares and foxes took their way in the evening to the plain below. There were two channels or gullies made by the rains, leading from these rocks to the lower ground. Near one of these channels, the sportsman in question, and his attendant, stationed themselves one evening in hopes of being able to shoot some hares. They had not been there long, when they observed a fox coming down the gully, and followed by another. After playing together for a little time, one of the foxes concealed himself under a large stone or rock, which was at the bottom of the channel, and the other returned to the rocks. He soon, however, came back, chasing a hare before him. As the hare was passing the stone where the first fox had concealed himself, he tried to seize her by a sudden spring, but missed his aim. The chasing fox then came up, and finding that his expected prey had escaped, through the want of skill in his associate, he fell upon him, and they both fought with so much animosity, that the parties who had been watching their proceedings came up and destroyed them both.

Similarly, Mr. E. C. Buck records ('Nature,' viii., 303) the following interesting observation made by his friend Mr. Elliot, B.C.S., Secretary to Government, N.W.P.:—
He saw two wolves standing together, and shortly after noticing them was surprised to see one of them lie down in a ditch, and the other walk away over the open plain. He watched the latter, which deliberately went to the far side of a herd of antelopes standing in the plain, and drove them, as a sheep-dog would a flock of sheep, to the very spot where his companion lay in ambush. As the antelopes crossed the ditch, the concealed wolf jumped up as in the former case, seized a doe, and was joined by his colleague.

Mr. Buck draws attention to another closely similar display of collective instinct of wolves in the same district observed by a 'writer of one of the books on Indian sport.'
With reference to this case I wrote to 'Nature' as follows. The friend to whom I allude was the late Dr. Brydon, C.B. (the 'last man' of the Afghan expedition of 1841), whom I knew intimately for several years, and always found his observations on animals to be trustworthy:—
In response to the appeal which closes Mr. Buck's interesting letter ('Nature,' vol. viii., p. 302), the following instance of 'collective instinct' exhibited by an animal closely allied to the wolf, viz., the Indian jackal, deserves to be recorded. It was communicated to me by a gentleman (since deceased) on whose veracity I can depend. This gentleman was waiting in a tree to shoot tigers as they came to drink at a large lake (I forget the district), skirted by a dense jungle, when about midnight a large axis deer emerged from the latter and went to the water's edge. Then it stopped and sniffed the air in the direction of the jungle, as if suspecting the presence of an enemy; apparently satisfied, however, it began to drink, and continued to do so for a most inordinate length of time. When literally swollen with water it turned to go into the jungle, but was met on its extreme margin by a jackal, which, with a sharp yelp, turned it again into the open. The deer seemed much startled, and ran along the shore for some distance, when it again attempted to enter the jungle, but was again met and driven back in the same manner. The night being calm, my friend could hear this process being repeated time after time—the yelps becoming successively fainter and fainter in the distance, until they became wholly inaudible. The stratagem thus employed was sufficiently evident. The lake having a long narrow shore intervening between it and the jungle, the jackals formed themselves in line along it while concealed within the extreme edge of the cover, and waited until the deer was waterlogged. Their prey, being thus rendered heavy and short-winded, would fall an easy victim if induced to run sufficiently far,i.e., if prevented from entering the jungle. It was, of course, impossible to estimate the number of jackals engaged in this hunt, for it is not impossible that as soon as one had done duty at one place, it outran the deer to await it in another.A native servant who accompanied my friend told him that this was a stratagem habitually employed by the jackals in that place, and that they hunted in sufficient numbers 'to leave nothing but the bones.' As it is a stratagem which could only be effectual under the peculiar local conditions described, itmust appear that this example of collective instinct is due to 'separate expression,' and not to 'inherited habit.'Cases of collective instinct are not of unfrequent occurrence among dogs. For the accuracy of the two following I can vouch. A small Skye and a large mongrel were in the habit of hunting hares and rabbits upon their own account, the small dog having a good nose, and the larger one great fleetness. These qualities they combined in the most advantageous manner, the terrier driving the cover towards his fleet-footed companion which was waiting for it outside.The second case is remarkable for a display of sly sagacity. A friend of mine in Ross-shire had a small terrier and a large Newfoundland. One day a shepherd called upon him to say that his dogs had been worrying sheep the night before. The gentleman said there must be some mistake, as the Newfoundland had not been unchained. A few days afterwards the shepherd again called with the same complaint, vehemently asserting that he was positive as to the identity of the dogs. Consequently the owner set one watch upon the kennel and another outside the sheep enclosure, directing them (in consequence of what the shepherd had told him) not to interfere with the action of the dogs. After this had been done several nights in succession, the small dog was observed to come at daydawn to the place where the large one was chained; the latter immediately slipped his collar, and the two animals made straight for the sheep. Upon arriving at the enclosure the Newfoundland concealed himself behind a hedge, while the terrier drove the sheep towards his ambush, and the fate of one of them was quickly sealed. When their breakfast was finished the dogs returned home, and the larger one, thrusting his head into his collar, lay down again as though nothing had happened. Why this animal should have chosen to hunt by stratagem prey which it could easily run down, I cannot suggest; but there can be little doubt that so wise a dog must have had some good reason.

A similar instance of the display of collective instinct is thus narrated by M. Dureau de la Malle:—
I had at one time two sporting dogs, the one an excellent pointer with a very smooth skin, and of remarkable beauty and intelligence; the other was a spaniel with long and thick hair, but which had not been taught to point, but only coursed in the woods like a harrier. Mychâteauis situated on a level spot of ground, opposite to copse wood filled with hares andrabbits. When sitting at my window, I have observed these two dogs, which were at large in the yard, approach and make signs to each other, and first glancing at me, as if to see if I offered any obstacle to their wishes, step away very gently, then quicken their pace when they were at a little distance from my sight, and finally dart off at full speed when they thought I could neither see them nor order them back. Surprised at this mysterious manœuvre, I followed them, and witnessed a singular sight. The pointer, who seemed to be the leader of the enterprise, had sent the spaniel out to beat the bushes, and give tongue at the opposite extremity of the bushwood. As to himself, he made with slow steps the circuit of the wood by following it along the border, and I observed him stop before a passage much frequented by rabbits, and there point. I continued at a distance to observe how the intrigue was going to end. At length I heard the spaniel, which had started a hare, drive it with much tongue towards the place where its companion was lying in ambush, and the moment that the hare came out of the passage to gain the fields, the latter darted upon it and brought it to me with an air of triumph. I have seen these two dogs repeat this same manœuvre more than a hundred times; and this conformity has convinced me that it was not accidental, but the result of a concerted agreement and combined plan of operations understood beforehand.

Again, among Mr. Darwin's MSS., I find a letter from Mr. H. Reeks (1871), which says that the wolves of Newfoundland adopt exactly the same stratagem for the capture of deer in winter as that which is adopted by the hunters. That is to say, some of the pack secrete themselves in one or more of theleewarddeer-paths in the forest or 'belting,' while one or two wolves make a circuit round the herd of deer to windward. The herd invariably retreats by one of its accustomed runs, and 'it rarely happens . . . . that the wolves do not manage by this stratagem to secure a doe or young stag.' And Leroy, in his book on Animal Intelligence, narrates closely similar facts of the wolves of Europe as having fallen within his own observation.
