is consequently formed by the shelving of the inferior surface alone, their breadth remaining the same throughout the whole of their enormous length, and their power being proportionally increased; an admirable provision for enabling the animal to exercise to the fullest extent his propensity for digging up the ground, either in search of food or for other purposes. It appears, however, on the other hand, to unfit him for climbing trees, which he never attempts; and this remarkable circumstance in his habits affords a striking distinction between him and all the other Bears, which are essentially climbers. Of all the quadrupeds which inhabit the northern regions of the American continent, the Grizzly Bear is unquestionably the most formidable and the most dreaded. Superior to the rest of his tribe, not excepting even the polar species, in bulk, in power, in agility, and in the ferocity of his disposition, it is not to be wondered at that he should be regarded by the native Indians with an almost superstitious terror, and that some portion of this feeling should have been communicated even to the civilized travellers, who have occasionally met with him in the wild and desolate regions which are subject to his devastations. In the Journals of some of these travellers we find recorded such astonishing instances of his strength, ferocity, and extraordinary tenacity of life as would indeed amaze us, were we not aware how much the human mind is prone, under certain circumstances, to fall into exaggeration, in many cases most certainly unintentional. Making, however, all due allowances for the existence of this very natural feeling, we are bound to acknowledge that there are few animals who can compete with this terrible beast; and that to be made the object of his pursuit is an occurrence well calculated to alarm the stoutest heart, even when provided with the most certain and deadly weapons of human invention, guided by the most experienced eye, and directed by the steadiest hand.
