THE AMERICAN BLACK BEAR.

发布时间:2020-06-19 作者: 奈特英语

Ursus americanus. Pallas.

We have now arrived at the closing group of the true Carnivora; a group which, although less sanguinary in its habits than almost any of those which we have hitherto had occasion to notice, and endowed by nature with a capacity of subsisting entirely on vegetable substances, comprehends nevertheless, among the closely allied species of which it is composed, not merely the largest, but even some of the most formidable, of the carnivorous Mammalia.

Both in outward shape and internal characters, these clumsy, sluggish, and uncouth animals offer a perfect contrast to the light, active, and elegant forms of the[116] tribe with which we commenced our series. Instead of the compressed and lengthened body, with its soft, sleek, and variegated covering, and the long and graceful tail by which it is terminated, we have a broad, awkward, and thickset figure, covered with a rough, shaggy, and unattractive fur, and ending in a scarcely visible appendage, serving neither for ornament nor use. The difference in gait and motion is as remarkable as that of shape; for while the one glides gently along, as it were on tiptoe, or bounds onwards with the velocity of thought, the other appears to be oppressed by the weight of his ponderous and unwieldy bulk, and supporting himself on the full expansion of his dilated paws, scarcely moves without the semblance of an effort. The short and rounded jaws of the cats, with their close and regular series of powerful cutting and lacerating teeth, and their rough and rasplike tongue, are supplied by a broad and lengthened snout, teeth of a character totally different in almost every essential point, and a soft, smooth, and extensible tongue. The claws too, which in the cats are strongly curved, exceedingly sharp at their edges, tapering gradually to a fine point, and capable of being entirely retracted within their sheaths, are here indeed of great power, and sometimes even considerably arched, but rounded in their surfaces, more or less blunted at their extremities, and constantly protruded to their full extent. In this manner might the contrast be pursued through almost every organ; but our limits warn us that we must at once proceed to the enumeration of the essential characters which combine the Bears into a well marked group.

These characters are derived, first, from their completely[117] plantigrade walk, the whole sole being at all times closely applied to the surface on which they tread; secondly, from their claws, of which they have five on each foot; thirdly, from the extreme shortness of their tail; and lastly, from the form and arrangement of their teeth. These consist of the usual number of incisors and canines, the latter being in general very robust, and of a series of molars, which, when complete, amount to six on each side in each jaw; the posterior three having flat and expanded surfaces surmounted by broad and blunted tubercles, and lying closely in contact with each other. Between them and the canines exists a considerable space, which is or should be occupied by three smaller and obtusely pointed teeth; but this number is seldom found entire, one or more of them being generally absent, and the series being thus rendered incomplete.

The Black Bear of America is distinguished from his fellows, and more especially from the brown bear of Europe, which he approaches most nearly in size and form, by few very striking external differences, except the colour of his fur. His forehead has a slight elevation; his muzzle is elongated, and somewhat flattened above; and his hair, though long and straight, has less shagginess than that of most of the other species of the group. In colour it is of a uniform shining jet-black, except on the muzzle, where it is short and fawn-coloured, becoming almost gray on the lips and sides of the mouth. This, however, it should be observed, is the character only of the full-grown animal: the young are first of a bright ash colour, which gradually changes to a deep[118] brown, and finally fixes in the glossy black tint of mature age.

The habits and manners of the Black Bear resemble those of the brown almost as closely as his physical characters. In a state of nature he seeks the recesses of the forest, and passes his solitary life in wild and uncultivated deserts, far from the society of man, and avoiding even that of the animal creation. His usual food consists of the young shoots of vegetables, of their roots, which he digs up with his strong and arcuated claws, and of their fruits, which he obtains by means of the facility with which the same organs enable him to climb the loftiest trees. He possesses indeed the faculty of climbing in a most extraordinary degree, and frequently exercises it in the pursuit of honey, of which he is passionately fond. When all these resources fail him, he will attack the smaller quadrupeds, and sometimes even animals of considerable size; familiarity with danger diminishing his natural timidity, and the use of flesh begetting a taste for its continued enjoyment. He is also said, like the Polar Bear, to have a peculiar fondness for fish, and is frequently met with on the borders of lakes and on the coast of the sea, to which he has resorted for the gratification of this appetite. Notwithstanding his apparent clumsiness, he swims with the greatest dexterity, the excessive quantity of fat with which he is loaded serving to buoy him up in the water; in this way he frequently crosses the broadest rivers, or even very considerable arms of the sea.

The entire continent of North America, or perhaps it might be more correct to say, that immense portion of[119] its surface which still remains uncultivated and desolate, furnishes an abode to this species of bear, which is consequently as widely dispersed as any of his tribe. As his fur is of some value in commerce, although not so much sought after at the present day as it was formerly, his race has become an object of the cupidity of man, by whom they are frequently hunted for the sake of their skins. This chase is principally followed by the Indians, who are also attracted by the flavour of his flesh, of which, and especially of the fat, they partake with an avidity truly disgusting. Travellers, however, who have been reduced to the necessity of having recourse to this sort of food, speak of it as by no means despicable: the fat yields moreover a quantity of oil, which is often extremely serviceable. The Indians will sometimes attack these animals single-handed; and if they can manage to keep beyond the reach of their powerful grasp, which is almost irresistible, are sure of gaining the victory; as the bears, in the rampant posture which they always assume in self-defence, unconsciously expose their most vulnerable parts to the attack of the hunter. Snares are sometimes laid for them; but these are most frequently unsuccessful; that extreme caution, which is so strongly portrayed in their actions and demeanour, rendering them mistrustful of every thing. Nevertheless their gluttony will sometimes get the better of their prudence, and the bait of honey offers too tempting an allurement to be always resisted. At other times a whole tribe of Indians will assemble for the chase, and after having performed a variety of superstitious observances, beat the entire country for their game, drive a great number of them into a spot selected[120] for the purpose, and deal forth upon them wholesale destruction. They will also trace them to their retreats in the season of their lethargy, which occupies several of the winter months, and during which the bears are incapable of offering any effectual resistance.

In captivity the Black Bear is distinguished from the brown only by the less degree of docility and intelligence which he evinces: and the habits of the latter are so universally known that it would be useless to dwell upon them here. The specimen figured at the head of this article was presented to the Menagerie, in 1824, by Sir George Alderson, and is remarkably tame and playful. He has, until very lately, shared his den with the Hy?na, with whom he maintained a very good correspondence, except at meal-times, when they would frequently quarrel, in a very ludicrous manner, for a piece of beef, or whatever else might happen to furnish a bone of contention between them. The Hy?na, though by far the smallest of the two, was generally master; and the Bear would moan most piteously, and in a tone somewhat resembling the bleating of a sheep, while his companion quietly consumed the remainder of his dinner.
