It is not going beyond the bounds of truth to assert that the grizzly bear of the Rocky Mountains is as formidable an enemy as the hunter is called upon to meet, wherever the hunting-ground and whatever the animal which opponents to our assertion may set up. When caught out on the open prairie, where he can be attacked on horseback and lassoed, the chances are against the bear; but, in a broken country, woe to his assailants, unless life is saved by some trick; or, happy fortune; a lucky shot; a telling blow, like Sanchez's with his slung-shot; or, the fanciful drumming, such as was Kit's, on the noses of his antagonists; or, some other equally singular and unlooked-for expedient. The weight of one of these monsters often runs as high as fifteen hundred pounds; and, their fore paws, which they can manage with the greatest dexterity, frequently measure fourteen inches. The courage, sagacity and skill invariably evinced by this species of bear, when engaged in a fight, is not equaled by any other wild animal on the face of the globe, not excepting the lion. We take pleasure in here giving further publicity to the careful research and plain truths which have emanated from the pen of that distinguished and successful traveler Dr. Livingston. The new ideas which appear in his pages in regard to the courage of the "King of Beasts," have served, in a measure, to correct the general impression, and to bring down from its high-stilted hyperbole the courage, sagacity and terrible power of the lion, which, he states, are overrated. We do not desire to contradict published statements any farther than our own personal knowledge extends; hence, we give our authority for our statements in regard to the lion, very well satisfied ourself with Dr. Livingstone's love of truth and earnest candor. So much for the lion. Our statements in regard to the Rocky Mountain grizzly bear rest upon our own knowledge and investigation, gathered in his own haunts and on his own wild domain; and, as such, are given upon our own responsibility. Because brave American woodsmen can readily conquer the monarch of the American forest; and because the chicken-hearted Afric son, or dweller, trembles before the steady glare of the Afric King of Beasts, _ergo_ his bearship must in popular opinion, play subordinate to his lionship. For the sake of truth, we should like to see the Spanish arena once open for a fighting encounter between a Rocky Mountain bear and an African lion, full and native grown specimens of each. The bull-fights all good men abhor; but, such a battle would serve to set at rest a fast-growing doubt among naturalists; and, so far, would prove available to science and the cause of truth. We would readily stake a purse on the bear.
