Quadrupeds, What They Are and Where Found: A Book of Zoology for Boys
“The beaver-houses are built of the same materials as their dams, and are always proportioned in size to the number of inhabitants, which seldom exceeds four old and six to eight young ones; though, by chance, I have seen above double the number. Instead of order or regulation being observed in rearing their houses, they are of a much ruder structure than their dams; for, notwithstanding the sagacity of these animals, it has never been observed that they aim at any other convenience in their houses than to have a dry place to lie on; and there they usually eat their victuals, which they occasionally take out of the water. It frequently happens that some of the large houses are found to have one or more partitions (if they deserve that appellation), but it is no more than a part of the main building left by the sagacity of the beaver to support the roof. On such occasions it is common for these different apartments, as some are pleased to call them, to have no communication with each other but by water; so that, in fact, they may be called double or treble houses, rather than different apartments of the same house. I have seen a large beaver-house built in a small island that had near a dozen apartments under one roof; and, two or three of these only excepted, none of them had any communication with each other but by water. As there were beavers enough to inhabit each apartment, it is more than probable that each family knew their own, and always entered at their own door, without any further connection with their neighbours than a friendly intercourse, and to join their united labours in erecting their separate habitations, and building their dams where required. Travellers who assert that the beavers have two doors to their houses – one on the land side, and the other next the water – seem to be less acquainted with these animals than others who assign them an elegant suite of apartments. Such a construction would render their houses of no use, either to protect them from their enemies, or guard them against the extreme cold of winter.
“So far are the beavers from driving stakes into the ground when building their houses, that they lay most of the wood crosswise, and nearly horizontal, and without any other variation than that of leaving a hollow or cavity in the middle. When any unnecessary branches project inward they cut them off with their teeth, and throw them in among the rest, to prevent the mud from falling through the roof. It is a mistaken notion that the woodwork is first completed and then plastered; for the whole of their houses, as well as their dams, are, from the foundation, one mass of mud and wood, mixed with stones, if they can be procured. The mud is always taken from the edge of the bank, or the bottom of the creek or pond near the door of the house; and though their fore-paws are so small, yet it is held close up between them under their throat: thus they carry both mud and stones, while they always drag the wood with their teeth. All their work is executed in the night, and they are so expeditious, that in the course of one night I have known them to have collected as much as amounted to some thousands of their little handfuls. It is a great piece of policy in these animals to cover the outside of their houses every fall with fresh mud, and as late as possible in the autumn, even when the frost becomes pretty severe, as by this means it soon freezes as hard as a stone, and prevents their common enemy, the wolverene, from disturbing them during the winter; and as they are frequently seen to walk over their work, and sometimes to give a flap with their tail, particularly when plunging into the water, this has, without doubt, given rise to the vulgar opinion that they use their tails as a trowel, with which they plaster their houses; whereas that flapping of the tail is no more than a custom which they always preserve, even when they become tame and domestic, and more particularly so when they are startled.
“Their food consists of a large root, something resembling a cabbage-stalk, which grows at the bottom of the lakes and rivers. They also eat the bark of trees, particularly those of the poplar, birch, and willow; but the ice preventing them from getting to the land in the winter, they have not any bark to feed on in that season, except that of such sticks as they cut down in summer, and throw into the water opposite the doors of their houses; and as they generally eat a great deal, the roots above-mentioned constitute a principal part of their food during the winter. In summer they vary their diet by eating various kinds of herbage, and such berries as grow near their haunts during that season. When the ice breaks up in the spring the beavers always leave their houses, and rove about until a little before the fall of the leaf, when they return again to their old habitations, and lay in their winter-stock of wood. They seldom begin to repair their houses till the frost commences, and never finish the outer coat till the cold is pretty severe, as has been already mentioned. When they erect a new habitation they begin felling the wood early in the summer, but seldom begin to build until the middle or latter end of August, and never complete it till the cold weather be set in.
“Persons who attempt to take beavers in winter should be thoroughly acquainted with their manner of life; otherwise they will have endless trouble to effect their purpose, because they have always a number of holes in the banks, which serve them as places of retreat when any injury is offered to their houses, and in general it is in those holes that they are taken. When the beavers which are situated in a small river or creek are to be taken, the Indians sometimes find it necessary to stake the river across to prevent them from passing; after which they endeavour to find out all their holes or places of retreat in the bank. This requires much practice and experience to accomplish, and is performed in the following manner: – Every man being furnished with an ice-chisel, lashes it to the end of a small staff about four to five feet long; he then walks along the edge of the banks, and keeps knocking his chisel against the ice. Those who are acquainted with that kind of work well know by the sound of the ice when they are opposite to any of the beavers’ holes or vaults. As soon as they suspect any, they cut a hole through the ice big enough to admit an old beaver; and in this manner proceed till they have found out all their places of retreat, or at least as many of them as possible. While the principal men are thus employed, some of the under-strappers and the women are busy in breaking open the house – which at times is no easy task, for I have frequently known these houses to be five or six feet thick; and one, in particular, was more than eight feet thick in the crown. When the beavers find that their habitations are invaded, they fly to their holes in the banks for shelter; and on being perceived by the Indians, which is easily done, by attending to the motion of the water, they block up the entrance with stakes of wood, and then haul the beaver out of its hole, either by hand, if they can reach it, or with a large hook made for that purpose, which is fastened to the end of a long stick. The beaver is an animal which cannot keep long under at a time; so that when their houses are broken open, and all their places of retreat discovered, they have but one choice left, as it may be called – either to be taken in their house or their vaults; in general they prefer the latter; for where there is one beaver caught in the house, many thousands are taken in the vaults in the banks. Sometimes they are caught in nets, and, in summer, very frequently in traps.
“In respect to the beavers dunging in their houses, as some persons assert, it is quite wrong, as they always plunge into water to do it. I am the better enabled to make this assertion, from having kept several of them till they became so domesticated as to answer to their name, and follow those to whom they were accustomed in the same manner as a dog would do; and they were as much pleased at being fondled as any animal I ever saw. In cold weather they were kept in my own sitting-room, where they were the constant companions of the Indian women and children; and were so fond of their company, that when the Indians were absent for any considerable time, the beavers discovered great signs of uneasiness, and on their return showed equal marks of pleasure, by fondling on them, crawling into their laps, lying on their backs, sitting erect like a squirrel, and behaving like children who see their parents but seldom. In general, during the winter, they lived on the same food as the women did; and were immoderately fond of rice and plum-pudding; they would eat partridges and fresh venison very freely; but I never tried them with fish, though I have heard they will at times prey on them. In fact, there are few graminivorous animals that may not be brought to be carnivorous.”
The Musquash, or Musk-rat, is undoubtedly a beaver, and has been called at times the Little Beaver; but it has pleased the naturalists to constitute it a genus of itself, though there is only the one species known. Its habits are extremely like those of the beaver: it is aquatic, or amphibious, if you please – building itself a conical house in the midst of a swamp, or low islet, and feeding on shoots of trees, bits of green wood, leaves and stalks of nettles, and other herbaceous plants. Its fur bears a very great resemblance to that of the beaver, only it is shorter, and therefore less valuable. Notwithstanding this, it is an article of extensive commerce; and upwards of a million skins have been imported into England in a single year. The musquash might also be exterminated like the beaver; but being a smaller creature, and therefore less persecuted by the amateur sportsman, it is still common enough upon the streams of the northern and middle States of America. Further north it is plentiful; and the Hudson’s Bay Company procure a vast number of skins for annual exportation to Europe. Its name of musk-rat is derived from the scent of musk which the animal emits, and which is especially powerful during the season of rut.
It is possible that the musk-rat of Siberia, as well as several species of water-rats belonging to South America – and known vaguely by the name of Lutras and Nutrias – may be animals of the beaver kind, rather than Water-Rats or Otters, among which they are generally classed.

Squirrels
These pretty little animals are widely distributed over the earth; though to this remark Australia seems to form an exception, since no species has yet been discovered there. However, there is much of that great island continent yet to be explored; and perhaps it may turn out that Australia has its squirrels, as well as other parts of the world – no doubt squirrels with pouches.
In number of species – and also of individuals, it may be added – America excels all other countries, and the great forests of North America may be regarded as the head-quarters of the squirrel tribe; but, if we give precedence to size, the squirrels of the East Indian countries are entitled to the first place.
Animals known as Squirrels are of three very distinct kinds – viz., Squirrels, properly so called; Ground Squirrels: and Flying Squirrels. These three kinds are very naturally separated into three different genera; but the closet naturalists, not content with this simple division, have again subdivided them into other sub-genera, using very difficult names to distinguish them. In our little sketch we shall simply call them by the three names above-mentioned.
The Squirrels, properly so called, are not only tree-climbers, but, as every one knows, dwell habitually upon trees, and there make their nests and their home. And perfectly at home they are among the highest branches; for under no circumstances do they ever miss their footing, or are they in the slightest danger of falling. In fact, they can not only run with the greatest agility along the branches, but equally well with their backs downward; and can spring from branch to branch, and also from tree to tree, over wide intervals of many yards. They can also leap down from the tops of the tallest trees to the earth – a feat often witnessed by squirrel-hunters – and do so without the appearance of having received the slightest injury; for, without pausing a moment on the ground, they continue their flight towards some other tree, where they expect to find better shelter from the short gun or rifle of their human enemy.
The squirrel builds a nest in the tree, similar to that of some birds; but they have also in the same tree a more secure retreat in case of being pursued. This is a hole in the trunk or one of the larger limbs – some natural excavation caused by the decaying of a branch – in short, what is termed a “knot hole,” which is common in many kinds of timber. In this hole the squirrel usually lays up its store of winter food, consisting of nuts, beech-mast, etcetera; and here it takes refuge when hunted, finding the tree-cave a safe asylum. Unless decoyed out again, or, which often happens, frightened out again, by rubbing the trunk with a piece of stick, the squirrel must escape scot-free nine times out of ten, since no hunter would think of felling a huge tree to procure so insignificant a reward as the carcass of a squirrel; and without felling the tree, and splitting it up, too, the creature could not be reached. Various devices, however, are practised to decoy it forth; and these, unfortunately for the little refugee, too often succeed.
The squirrels are the life of the American woods – indeed, a journey through these great forests would often be very monotonous were it not enlivened by the presence and gambols of these beautiful creatures; and in the depth of winter, when the squirrels keep within their dark tree-caves, the solitude of the forest seems redoubled. But even during frost and snow, when the weather is fine and the sun shining brightly, a few will be seen venturing forth, as if to take an airing.
A great many species exist in the forests of North America; sometimes only one, and sometimes several, occupy the same district. They are of different colours and sizes – some as small as the common squirrel of England, while several species are three or four times as large. Some are grey, others brown grey, several species of a fox red, and those esteemed the most beautiful are of a uniform jet black. Several new species have lately been found in the forests of Oregon and California.
Their habits are all nearly alike; but to one species of Grey Squirrel belongs a habit as distinct as it is singular. This is their habit of collecting together in immense flocks of many thousands, and migrating over vast tracts of country, crossing broad rapid rivers, and staying at no obstacle. The object of this migration is not known, only that it appears to be the result of some impulse – such as excites to a similar movement the springboks of South Africa, the buffaloes of North America, and the passenger pigeons.
In Europe the squirrel is represented by the Common Squirrel of our own woods, and which is found throughout the whole of Northern Europe and Asia, wherever there are trees. Although of a reddish colour in England, as well as in France, it assumes different hues, according to the different countries it inhabits; and in the more northern latitudes it is quite grey. Another European species, distinct from the English squirrel, is a denizen of the Pyrenees and the Alps of Dauphiné.
The Palm Squirrel is a beautiful species belonging to the tropical parts of Africa and India, and dwelling principally upon the palm trees – as its name imports.
Another, known as the Barbary Squirrel, belongs to North Africa, and is also a dweller upon palm trees.
The largest, and perhaps the most richly-coated of the tribe, is the Malabar Squirrel of India, which is as large as a domestic cat. It also haunts among palm trees, and is fond of the milk of the cocoa-nut, either in a liquid or solid state.
There are squirrels also in Eastern Africa. India has several species, and the great islands of Madagascar, Ceylon, Java, Borneo, Sumatra, etcetera, have each one or more species of large and beautiful squirrels.
The Ground Squirrels differ from the true squirrels in several respects, though the chief difference lies in the fact that the former make their nest or lair upon the ground, while the latter universally lodge themselves aloft among the branches. The Ground Squirrels can climb, and appear to ascend trees almost as nimbly as their congeners; but they rarely do so unless when pursued, and then but seldom go beyond the lower forks or branches. Their nest is usually in some hole or cavity among the roots, though several species have been lately discovered in rocky regions, dwelling in the crevices of rocks. They approach in habits to the marmot tribe, and seem to link the tree squirrels with these last. Usually, these ground squirrels are striped longitudinally with black, red, and white stripes, giving them a fine appearance; and the species are of different dimensions, from that of the ordinary squirrel to the size of a mouse. In America, for a long time, but one kind was supposed to exist; but latterly a great number of species have been observed and described: denizens of the far West – of the prairies, and remote valleys of the Rocky Mountains.
The African species of ground squirrel, already mentioned as the Palm Squirrel, has its dwelling among the palm trees, on the fruit and roots of which – especially that of the date-palm – it subsists. It is also an inhabitant of India, where there is at least one other species of palm ground squirrel.
In Europe, and throughout the whole of Northern Asia, the ground squirrels are represented by the burunduk– a very interesting little species, quite similar in habits to those of North America.
The Flying Squirrels are the last of the group. These are the most singular of all, and resemble great bats more than squirrels. They possess the power, not exactly of flight, but of making very long leaps from a higher to a lower level, so long that they might almost be regarded as flights. They can pass from one tree to another standing more than a hundred yards apart, and this without descending more than a few feet below the level from which they started. This feat they are enabled to perform by means of a broad membrane that extends from the skin of their fore-legs to that of their thighs, and which, when stretched out, endows them with the properties of a parachute. Their bodies, too, have a flattened shape like the bats; and this also helps to sustain them in the air.
They are true squirrels, however, living upon trees, as the common squirrels do, and looking very like the latter, notwithstanding their winged legs. In one point, however, they differ essentially from the common squirrels; and that is, they are nocturnal in their habits. In the daytime they are never seen, except by accident; but in the twilight, and during a clear night, they may be observed making their long leaps from tree to tree, through the glades or along the edges of the forest. There are several species inhabiting the forests of America, and of late California has yielded several new ones. In the tropical forests of America there are several large species, and the Old World has its flying squirrel in the Polatouka, which inhabits the pine forests of Northern Europe and Asia.
The largest species of these singular quadrupeds appears to belong to the Oriental Islands – to Java, Sumatra, the Philippines, and Moluccas, or Spice Islands, as also to Japan. The great Teguan, or flying squirrel of the Moluccas, is in reality as large as a cat!
The singular Ay-ay of Madagascar is sometimes classed among the squirrels and sometimes among the lemurs. It certainly bears a great resemblance to the squirrel family; but the habits of all animals belonging to Madagascar are so little known that it is difficult to assign them to that exact genus in which Nature intended they should be placed.
Chapter Twelve.
Hares, Rabbits, and other Rodents
The Hare, and its very near congener, the Rabbit, are animals too well-known to need description; but it is necessary to say that, besides the species of both, peculiar to Great Britain, there are many other kinds in other parts of the world. Even in Britain itself, including Ireland, there are several distinct sorts both of hares and rabbits; for the Irish hare is distinct, being a larger, stronger, and even swifter animal than the English hare, and having many other points peculiar to it. Moreover, in the northern and mountainous parts of Scotland there is found the Varying or Alpine Hare, whose fur changes in the winter season to a snowy whiteness. But I may here remark, that the Irish hare also possesses this singular power of transformation, since upon the mountains of the north, especially upon the Mourne range, in county Down, white hares have been frequently observed. Is this the Irish hare turned white, or the true Alpine hare of Pallas?
Hares and rabbits are peculiarly the denizens of cold countries, as their warm woolly covering would plainly indicate. In tropical climates their place is supplied by other kinds of rodents, that resemble them in habits, if not in “dress.” Of these other animals we shall presently speak. To the above remark, however a few partial exceptions may be brought forward; since there is a species existing in Egypt known as the Egyptian Hare, and there are three others at the Cape – the Rock Hare, the Burrow Hare, and the Vlakte Haas. These, however, differ very considerably from the common hares and rabbits of northern countries; and the remark still holds good, that in the tropics – properly so called – the hare does not exist: neither has any true hare been found in the new world of Australia.
Otherwise, hares are plenteous in the different continents of Europe, Asia, Africa, and America. In Asia there is a species inhabiting the regions of the Altai Mountains, and another peculiar to the Siberian territory, called the Tolai. There is an Indian species found in the Nepaul Mountains, and a curious variety, also a native of Nepaul and the Himalayas, known as the Woolly Hare of Thibet.
The Polar Hare, valued for its beautiful white fur, inhabits the countries around the Arctic Ocean, and is common in Labrador and the Hudson’s Bay territory. In North America, also, there are several other species of hares: the Marsh, or Swamp Hare, of the Southern United States, which dwells among the extensive marshes of the Carolinas and Louisiana, and which freely takes to the water; the Rabbit of the Middle States, which is a true hare, though from its small size usually termed a rabbit; the Californian Hare, indigenous to California, and also another Marsh Hare, belonging to the same country. Upon the prairies several distinct species have lately been discovered, among which the Sage Hare deserves especial mention. This kind derives its name from its being a dweller on the desert plains, where scarce any other vegetation exists except the artemisia, or wild sage plant, the leaves of which constitute the principal food of the animal, rendering its flesh almost uneatable.
The Calling Hares differ very much from the common hares and rabbits – so much as to constitute a separate genus. Their ears are shorter, and they are altogether without tails. Their habits, however, are very similar to those of the hare family, and they are therefore very naturally grouped with the latter. They derive their trivial name from the habit of uttering a note, which somewhat resembles the piping of a quail, and which can be heard at a very great distance. This note is repeated three or four times at night and morning, but is seldom heard during the middle of the day, unless when the weather is cloudy.
The calling hares are distributed over Asia and North America. At least two species belong to the Himalayan country, and one is found in Cabul. In Siberia and Northern Russia there is another, called the Eadajac; and several species inhabit the northern countries of America – some so small as scarcely to exceed the dimensions of a rat! The Little Chief is one of these tiny creatures long known; but late explorers of the Rocky Mountain regions have discovered a species still smaller than the little chief.
