CURIOSITIES RESPECTING ANIMALS.—(Continued.)

It would not be consistent with the plan of this work to embrace the whole natural history of the animal and vegetable kingdom. This is a Book of Curiosities; and it is our intention to present the reader with a sketch of the most remarkable things in the universe: our present subject, therefore, being curiosities respecting animals, we shall commence with—

The Beaver.—This animal was known to the ancients for its possession of that sebaceous matter called castor, secreted by two large glands near its genitals and anus, and of which each animal has about two ounces; but they appear to have been unacquainted with its habits and economy, with that mental contrivance and practical dexterity, which in its natural state so strikingly distinguish it. Beavers are found in the most northern latitudes of Europe and Asia, but are most abundant in North America.

In the months of June and July, they assemble in large companies to the number of two hundred, on the banks of some water, and proceed to the formation of their establishment. If the water be subject to risings and fallings, they erect a dam, to preserve it at a constant level; where this level is naturally preserved, this labour is superseded. The length of this dam is occasionally eight feet. In the preparation of it, they begin with felling some very high, but not extremely thick tree, on the border of a river, which can be made to fall into the water; and, in a short time, this is effected by the united operation of many, with their fore-teeth, the branches being afterwards cleared by the same process. A multitude of smaller trees are found necessary to complete the fabric, and many of these are dragged from some distance by land, and formed into stakes; the fixing of which is a work of extreme difficulty and perseverance, some of the beavers with their teeth raising their large ends against the crossbeam, while others at the bottom dig with their fore-feet the holes in which the points are to be sunk. A series of these stakes, in several rows, is established from one bank of the river to the other, in connection with the cross-tree, and the intervals between them are filled up by vast quantities of earth, brought from a distance, and plashed with materials adapted to give it tenacity, and prevent its being carried off. The bark is formed at the bottom, of about the width of twelve feet, diminishing as it approaches the surface of the water, to two or three; being thus judiciously constructed to resist its weight and efforts by the inclined plane instead of perpendicular opposition.

These preparations, of such immense magnitude and toil, being completed, they proceed to the construction of their mansions, which are raised on piles near the margin of the stream or lake, and have one opening from the land, and another by which they have instant access to the water. These buildings are usually of an orbicular form, in general about the diameter of ten feet, and comprehending frequently several stories. The foundation walls are nearly two feet in thickness, resting upon planks or stakes, which constitute also their floors. In the houses of one story only, the walls, which in all cases are plastered with extreme neatness both externally and within, after rising about two feet perpendicularly, approach each other, so as at length to constitute, in closing, a species of dome. In the application of the mortar to their habitations, the tails as well as feet of the beavers are of essential service. Stone, wood, and a sandy kind of earth, are employed in their structures, which, by their compactness and strength, completely preclude injury from winds and rain. The alder, poplar, and willow, are the principal trees which they employ; and they always begin their operations on the trunk, at nearly two feet above the ground; nor do they ever desist from the process till its fall is completed. They sit instead of stand, at this labour, and while reducing the tree to the ground, derive a pleasure at once from the success of their toils, and from the gratification of their palate and appetite by the bark, which is a favourite species of food to them, as well as the young and tender parts of the wood itself.

For their support in winter, ample stores are laid up near each separate cabin; and occasionally to give variety and luxury to their repasts during a long season, in which their stores must have become dry and nearly tasteless, they will make excursions into the neighbouring woods for fresh supplies. Depredations by the tenants of one cabin on the magazines of another are unknown, and the strictest notions of property and honesty are universal. Some of their habitations will contain six only, others twelve, and some even twenty or thirty inhabitants; and the whole village or township contains in general about twelve or fourteen habitations. Strangers are not permitted to intrude on the vicinity; but, amidst the different members of the society itself, there appears to prevail that attachment and that friendship which are the natural result of mutual co-operation, and of active and successful struggles against difficulty. The approach of danger is announced by the violent striking of their tails against the surface of the water, which extends the alarm to a great distance; and, while some throw themselves for security into the water, others retire within the precincts of their cabins, where they are safe from every enemy but man.

The neatness as well as the security of their dwellings is remarkable, the floors being strewed over with box and fir, and displaying the most admirable cleanness and order. Their general position is that of sitting, the upper part of the body, with the head, being considerably raised, while the lower touches, and is somewhat indeed immersed in, the water. This element is not only indispensable to them in the same way as to other quadrupeds, but they carefully preserve access to it even when the ice is of very considerable depth, for the purpose of regaling themselves by excursions to a great extent under the frozen surface. The most general method of taking them is by attacking their cabins during these rambles, and watching their approach to a hole dug in the ice at a small distance, to which they are obliged, after a certain time, to resort for respiration.

If a man, who had never been informed of the industry of beavers and their manner of building, were shewn the edifices that they construct, he would suppose them to be the work of most eminent architects. Every thing is wonderful in the labours of these amphibious animals; the regular plan, the size, the solidity, and the admirable art of these buildings, must fill every attentive observer with astonishment.

The works of beavers have a great resemblance to those of men; and upon their first appearance we may imagine them to be produced by rational and thinking beings; but when we examine them nearer, we shall find that in all their proceedings, these animals do not act upon the principles of reason, but by an instinct which is implanted in them by nature. If reason guided their labours, we should naturally conclude that the buildings which they now construct would be very different from those they formerly made, and that they would gradually advance towards perfection. But we find that they never vary in the least from the rules of their forefathers, never deviate from the circle prescribed to them by nature, and the beavers of to-day build exactly after the same plan as those which lived before the deluge. But they are not the less worthy of our admiration. In these sagacious creatures we have an example of the great diversity there is in the instinct of animals—how superior is the instinct of the beaver to that of the sheep!

The flesh of the anterior part of the bodies of beavers resembles that of land animals in substance and flavour; while that of the lower possesses the taste, and smell, and lightness of fish.

The sexual union among these animals is connected with considerable individual choice, sentiment, and constancy.—Every couple pass together the autumn and winter, with the most perfect comfort and affection. About the close of winter, the females, after a gestation of four months, produce, in general, each two or three young, and soon after this period they are quitted by the males, who ramble into the country to enjoy the return of spring; occasionally returning to their cabins, but no longer dwelling in them. When the females have reared their young, which happens in the course of a few weeks, to a state in which they can follow their dams, these also quit their winter residence, and resort to the woods, to enjoy the opening bloom and renovated supplies of nature. If their habitations on the water should be impaired by floods, or winds, or enemies, the beavers assemble with great rapidity to repair the damage. If no alarm of this nature occurs, the summer is principally spent by them in the woods, and on the advance of autumn they assemble in the scene of their former labours and friendships, and prepare with assiduity for the confinement and rigours of approaching winter.

When taken young, the beaver may be tamed without difficulty; but it exhibits few or no indications of superior intelligence. Some beavers are averse to that association which so strikingly characterizes these animals in general, and satisfy themselves with digging holes in the banks of rivers, instead of erecting elaborate habitations. The fur of these is comparatively of little value.

Another subject of animal curiosity is, The Mole.—This animal is about six inches in length, without the tail. Its body is large and cylindrical, and its snout strong and cartilaginous. Its skin is of extraordinary thickness, and covered with a fur, short, but yielding to that of no other animal in fineness. It hears with particular acuteness, and, notwithstanding the popular opinion to the contrary, possesses eyes, which it is stated to be able to withdraw or project at pleasure. It lives partly on the roots of vegetables, but principally on animal food, such as worms and insects, and is extremely voracious and fierce. Shaw relates, from Sir Thomas Brown, that a mole, a toad, and a serpent, have been repeatedly inclosed in a large glass vase, and that the mole has not only killed the others, but has devoured a very considerable part of them. It abounds in soft ground, in which it can dig with ease, and which furnishes it with a great supply of food. It forms its subterraneous apartments with great facility by its snout and feet, and with a very judicious reference to escape and comfort. It produces four or five young in the spring, in a nest a little beneath the surface, composed of moss and herbage. It is an animal injurious to the grounds of the farmer, by throwing up innumerable hills of mould, in the construction of its habitation, or the pursuit of its food, and many persons obtain their subsistence from the premiums, which are, on this account, given for their destruction. Moles can swim with considerable dexterity, and are thus furnished with the means of escape in sudden inundations, to which they are frequently exposed. In Ireland, the mole is unknown.

The Common Frog.—This is an animal so well known, that it needs no description: but some of its properties are very singular. Its spring, or power of taking large leaps, is remarkably great, and it is the best swimmer of all four-footed animals. Its parts are finely adapted for those ends, the fore members of the body being very lightly made, the hind legs and thighs very long, and furnished with very strong muscles. While in a tadpole state, it is entirely a water animal, for in this element the spawn is cast. As soon as frogs are released from their tadpole state, they immediately take to land; and if the weather has been hot, and there fall any refreshing showers, the ground for a considerable space is perfectly blackened by myriads of these animalcules, seeking for some secure lurking places. Some persons not taking time to examine into this phenomenon, imagined them to have been generated in the clouds, and showered on the earth: but had they, like Mr. Derham, traced them to the next pool, they would have found a better solution of the difficulty. As frogs adhere closely to the backs of their own species, so we know they will do the same by fish. That they will injure, if not entirely kill carp, is a fact indisputable, from the following relation.

Not many years ago, on fishing a pond belonging to Mr. Pitt, of Encomb, Dorsetshire, great numbers of the carp were found, each with a frog mounted on it, the hind legs clinging to the back, and the fore legs fixed to the corner of each eye of the fish, which were thin and greatly wasted, teased by carrying so disagreeable a load. The croaking of frogs is well known; and from that, in fenny countries, they are distinguished by ludicrous titles,—thus they are styled Dutch nightingales, and Boston waites. Yet there is a time of the year when they become mute, neither croaking nor opening their mouths for a whole month; this happens in the hot season, and that is in many places known to the country people by the name of the paddock-moon. It is said, that during that period their mouths are so closed, that no force (without killing the animal) will be capable of opening them. These, as well as other reptiles, feed but a small space of the year. Their food is flies, insects, and snails. During winter, frogs and toads remain in a torpid state; the last of which will dig into the earth, and cover themselves with almost the same agility as the mole.

Not less remarkable is The Common Toad.—This is the most deformed and hideous of all animals. The body is broad, the back flat, and covered with a pimply dusky hide; the belly large, swagging, and swelling out; the legs short, and its pace laboured and crawling; its retreat gloomy and filthy: in short, its general appearance is such as to strike one with disgust and horror. Yet it is said that its eyes are fine. Ælian and other ancient writers tell many ridiculous fables of the poison of the toad.

This animal was believed by some old writers to have a stone in its head fraught with great virtues, medical and magical: it was distinguished by the term of, the reptile, and called the toad-stone, bufonites, krottenstern, and other names, but all its fancied powers vanished on the discovery of its being nothing but the fossil tooth of the sea-wolf, or of some other flat-toothed fish, not unfrequent in our island, as well as several other countries. But these fables have been long exploded. And as to the notion of its being a poisonous animal, it is probable that its excessive deformity, joined to the faculty it has of emitting a juice from its pimples, and a dusky liquid from its hind parts, is the foundation of the report. That it has any noxious qualities, there seem to be no proofs in the smallest degree satisfactory, though we have heard many strange relations on that point. On the contrary, many have taken them in their naked hands, and held them long without receiving the least injury. It is also well known that quacks have eaten them, and have squeezed their juices into a glass, and drank them with impunity. They are also a common food to many animals; to buzzards, owls, Norfolk plovers, ducks, and snakes, which would not touch them, were they in any degree noxious.The fullest information concerning the nature and qualities of this animal is contained in letters from Mr. Arscott and Mr. Pitfield to Dr. Milles, communicated to Mr. Pennant; concerning a toad that lived above thirty-six years with them, was completely tame, and became so great a favourite that most of the ladies in the neighbourhood got the better of their prejudices so far as to be anxious to see it fed. Its food was insects, such as millepedes, spiders, ants, flies, &c. but it was particularly fond of flesh worms, which were bred on purpose for it. It never appeared in winter, but regularly made its appearance in the spring, when the warm weather commenced, climbing up a few steps, and waiting to be taken up, carried into the house, and fed upon a table. Before it attacked the insects, it fixed its eyes on them, and remained motionless for a quarter of a minute, when it attacked them by an instantaneous motion of its tongue, darted on the insect with such rapidity that the eye could not follow it, whereby the insect stuck to the tip of its tongue, and was instantly conveyed to its mouth. This favourite toad at last lost its life, in consequence of being attacked by a tame raven, which picked out one of its eyes; and although the toad was rescued, and lived a year longer, it never recovered its health or spirit. It never showed any signs of rage, being never provoked.

Our next subject is an animal of great bulk, The Rhinoceros.—This quadruped is exceeded in size only by the elephant. Its usual length, not including the tail, is twelve feet, and the circumference of its body nearly the same. Its nose is armed with a horny substance, projecting, in the full-grown animal, nearly three feet, and is a weapon of defence, which almost secures it from every attack. Even the tiger, with all his ferocity, is but very rarely daring enough to assail the rhinoceros. Its upper lip is of considerable length and pliability, acting like a species of snout, grasping the shoots of trees and various substances, and conveying them to the mouth; and it is capable of extension and contraction at the animal’s convenience. The skin is, in some parts, so thick and hard as scarcely to be penetrable by the sharpest sabre, or even by a musket-ball. These animals are found in Bengal, Siam, China, and in several countries of Africa; but are far less numerous than the elephant, and of sequestered solitary habits. The female produces only one at a birth; and at the age of two years the horn is only an inch long, and at six only of the length of nine inches. The rhinoceros is not ferocious, unless provoked, when he exhibits paroxysms of rage and madness, and is highly dangerous to those who encounter him. He runs with great swiftness, and rushes through brakes and woods with an energy to which every thing yields. He is generally, however, quiet and inoffensive. Its food consists entirely of vegetables, the tender branches of trees, and succulent herbage, of which it will devour immense quantities. It delights in retired and cool situations, near lakes and streams, and appears to derive one of the highest satisfactions from the practice of rolling and wallowing in mud,—in this respect bearing a striking resemblance to the hog.

Many varieties of this formidable animal are found in Asia and Africa.
The above figure represents the Asiatic variety, which has but one horn.

Of the African rhinoceros, Mr. Cumming, the famous hunter, describes several kinds.
The above figure represents the two-horned kind, which is found nowhere but in Africa.
Mr. Cumming killed many of this kind.

This animal was exhibited, by Augustus, to the Romans, and is supposed to be the unicorn of the scripture, as it possesses the properties ascribed to that animal, of magnitude, strength, and swiftness, in addition to that peculiarity of a single horn, which may be considered as establishing their identity. This animal can distinguish, by its sight, only what is directly before it, and always, when pursued, takes the course immediately before it, almost without the slightest deviation from a right line, removing every impediment. Its sense of smelling is very acute, and also of hearing, and, on both these accounts, the hunters approach him against the wind. In general, they watch his lying down to sleep, when, advancing with the greatest circumspection, they discharge their muskets into his belly. The flesh is eaten both in Africa and India.

We now proceed to The Crocodile.—This animal is a native both of Africa and Asia, but is most frequently found in the former, inhabiting its vast rivers, and particularly the Niger and the Nile. It has occasionally been seen of the length of even thirty feet, and instances of its attaining that of twenty are by no means uncommon. It principally subsists on fish, but such is its voracity, that it seizes almost every thing that comes within its reach. The upper part of its body is covered with a species of armour, so thick and firm, as to be scarcely penetrable with a musket-ball; and the whole body has the appearance of an elaborate covering of carved work. It is an oviparous animal, and its eggs scarcely exceed in size those of a goose. These eggs are regarded as luxuries by the natives of some countries of Africa, who will also with great relish partake of the flesh of the crocodile itself. When young, the small size and weak state of the crocodile prevent its being injurious to any animal of considerable bulk or strength; and those which have been brought living to England have by no means indicated that ferocious and devouring character which they have been generally described to possess; a circumstance probably owing to the change of climate, and the reducing effect of confinement.

In its native climate its power and propensity to destruction are unquestionably great, and excite in the inhabitants of the territories near its haunts a high degree of terror. It lies in wait near the banks of rivers, and, with a sudden spring, seizes any animal that approaches within its reach, swallowing it with an instantaneous effort, and then rushing back into its watery recesses, till renewed appetite stimulates the repetition of its insidious exertions. These animals were occasionally exhibited by the Romans among their collections of the natural wonders of the provinces; and Scaurus and Augustus are both recorded to have entertained the people with a sight of these new and formidable objects.

It is reported by some travellers, that crocodiles are capable of being tamed, and are actually kept in a condition of harmless domestication at the grounds and artificial lakes of some African princes, chiefly as appendages of royal splendour and magnificence. A single negro will often attack a crocodile, and by spearing it between the scales of the belly, where it is easily penetrable, secure its destruction. In some regions these animals are hunted by dogs, which, however, are carefully disciplined to the exercise, and are armed with collars of iron spikes.

Aristotle appears to have been the first who asserted that the under jaw of the crocodile was immoveable, and from him it was transmitted and believed for a long succession of ages. But the motion of the jaw in this animal is similar to that of all other quadrupeds. The ancients also thought it destitute of a tongue; an idea equally false. The tongue, however, is more fixed in this than in other animals, to the sides of its mouth, and less capable, therefore, of being protruded.—The eggs of the crocodile are deposited in the mud or sand of the banks of rivers, and immediately on being hatched, the young move towards the water; in their passage to which, however, vast numbers are intercepted by ichneumons and birds, which watch their progress.

The Alligator, or American Crocodile, has a vast mouth, furnished with sharp teeth; from the back to the end of the tail, it is serrated; its skin is tough and brown, and covered on the sides with tubercles. This dreadful species, which grows to the length of 17 or 18 feet, is found in the warmer parts of North America, and is most numerous, fierce, and ravenous, towards the south. Yet, in Carolina, it never devours the human species, but on the contrary, shuns mankind; it, however, kills dogs as they swim the rivers, and hogs which feed in the swamps. It is often seen floating like a log of wood on the surface of the water, and is mistaken for such by dogs and other animals, which it seizes, draws under water, and devours. Like the wolf, when pressed by long hunger, it will swallow mud, and even stones, and pieces of wood. They often get into the wears in pursuit of fish, and do much mischief by tearing them to pieces. They are torpid during winter, in Carolina, and retire into their dens, which they form by burrowing far under ground. They make the entrance under water, and work upwards. In spring they quit their retreats, and resort to the rivers, and chiefly seek their prey near the mouth, where the water is brackish. They roar and make a dreadful noise at first leaving their dens, and against bad weather. The female lays a vast number of eggs in the sand, near the banks of lakes and rivers, and leaves them to be hatched by the sun: multitudes are destroyed as soon as hatched, either by their own species, or by fish of prey. In South America, the carrion vulture is the instrument of Providence to destroy multitudes; and it thus prevents the country from being rendered uninhabitable.

The following account of Eastern Alligators is extracted from Forbes’s Oriental Memoirs.

The eastern districts of Travancore, intersected by lakes and rivers, abound with amphibious animals, especially alligators and seals. There seems to be no essential difference between the alligator of India, and the Egyptian crocodile; lacerta alligator, and lacertus crocodilus. Naturalists seem to confine the alligator to South America, the crocodile to Asia and Africa; but in India the lacerta crocodilus, generally called the alligator, is from five to twenty feet long, shaped like the genus to which he belongs; the back is covered with impenetrable scales; the legs short, with five spreading toes on the fore feet, and four in a straight line on the hinder, armed with claws: the alligator moves slowly, its whole formation being calculated for strength, the back bone firmly jointed, and the tail a most formidable weapon: in the river, he eagerly springs on the wretch unfortunately bathing within his reach, and either knocks him down with his tail, or opens his wide mouth for his destruction, armed with numerous sharp teeth of various lengths; by which, like the shark, he sometimes severs the human body at a single bite: the annals of the Nile and Ganges, although wonderful, are not fabulous. The upper jaw only of the alligator was thought to be moveable; but that is now completely disproved: the eyes are of a dull green, with a brilliant pupil, covered by a transparent pellicle, moveable as in birds: from the heads of those of large size, musk is frequently extracted.

It may not be improper in this place to introduce to the reader’s notice, one of the greatest curiosities of its kind, which late ages have produced; that is, a Fossil Crocodile.

This is the skeleton of a large crocodile, almost entire, found at a great depth under ground, bedded in stone. This was in the possession of Linkius, who wrote many pieces in natural history, and particularly an accurate description of this curious fossil. It was found in the side of a large mountain in the midland part of Germany, and in a stratum of black fossil stone, somewhat like our common slate, but of a coarser texture, the same with that in which the fossil fishes in many parts of the world are found. This skeleton had the back and ribs very plain, and was of a much deeper black than the rest of the stone; as is also the case with the fossil fishes, which are preserved in this manner. The part of the stone where the head lay was not found; this being broken off just at the shoulders, but that irregularly; so that in one place a part of the back of the head was visible in its natural form. The two shoulder-bones were very fair, and three of the feet were well preserved: the legs were of their natural shape and size; and the feet preserved even to the extremities of the five toes of each.

Our next subject is named The Ornithorhynchus Paradoxus, and is a very singular quadruped, remarkable for its structure. The head is similar to that of a duck, which would lead to the supposition that it belonged to an aquatic bird. Both jaws are as broad and low as those in a duck, and the calvaria has no traces of a suture, as is generally the case in full-grown birds. In the cavity of the skull there is a considerably bony falx, which is situated along the middle of the os frontis, and the ossa bregmatis. The mandible of this animal consists of a beak, the under part of which has its margin indented as in ducks, and of the proper instrument for chewing that is situated behind within the cheeks. Dr. Shaw says it has no teeth, though Mr. Home found, in a specimen examined by him, two small and flat molar teeth on each side of the jaws. The fore part of this mandible, or beak, is covered and bordered with a coriaceous skin, in which three parts are to be distinguished, within the proper integument of the beak. Into these three parts of that membrane numerous nerves are distributed, intended, probably, as the organs of feeling, a sense which, besides men, few mammalia enjoy; that is, few animals possess the faculty of distinguishing the form of external objects and their qualities, by organs destined for that purpose,—a property very different from the common feeling, by which every animal is able to perceive the temperature and presence of sensible objects, but without being informed, by the touch, of their peculiar qualities. Thus the skin in the wings of the bat, and its ear, are supposed the organs of common feeling, by means of which they are enabled to flutter, after being blinded, without flying against any thing. The whiskers of many animals appear likewise to serve the same purpose of informing them of the presence of sensible bodies, and hence they have been compared to the antennÆ of insects.

But to return to the ornithorhynchus: It is an animal which from the similarity of its abode, and the manner of searching for food, agrees much with the duck, on which account it has been provided with an organ for touching, viz. with the integument of the beak, richly endowed with nerves. This instance of analogy in the structure of a singular organ of sense in two species of animals, from classes quite different, is a most curious circumstance in comparative physiology, and hence the ornithorhynchus is looked upon as one of the most remarkable phenomena in zoology.

We shall close this chapter with an account of The Marmot, or Mountain-Rat of Switzerland.—This rat is almost the size of a leveret, and resembles a common rat very much in appearance. These little creatures live together in societies, and have different dwellings for winter and summer; their fore paws are remarkably strong, which qualifies them for scooping out their burrows. The same form is always preserved in the construction of their dwellings, which consist of a long passage, just big enough to let the marmot enter, leading to two apartments; the largest of these serves the whole family for a chamber, where they lie close together, in a torpid state, rolled up like hedge-hogs, during the cold season, as dormice do in England. When they betake themselves to their winter quarters, after having lined their chamber with soft hay, they carefully stop up the entrance with a sort of cement, which they make of earth, mixed with stones and dry grass. Before they collect the grass, either for food, or for their winter habitations, they form themselves into a circle, sitting on their hind legs, looking with a cautious eye on every side. If the least thing stirs that alarms them, the first which perceives it makes a particular kind of cry, which its next neighbour repeats, and so on till it goes round, when they hastily make their escape. They are often seen upon the slopes of the Alps, where grass is in plenty; but they love a warm sheltered situation, and change their residence according to the season.
