Several attempts have been made to raise the young grizzlies, but these have all been abortive, the animals proving anything but agreeable pets. As soon as grown to a considerable size, their natural ferocity displays itself, and their dangerous qualities usually lead to the necessity for their destruction. For a long time the great polar bear has been the most celebrated animal of his kind; and most of the bear-adventures have related to him. Many a wondrous tale of his prowess and ferocity has been told by the whaler and arctic voyager, in which this creature figures as the hero. His fame, however, is likely to be eclipsed by his hitherto less-known congener--the grizzly. The golden lure which has drawn half the world to California, has also been the means of bringing this fierce animal more into notice; for the mountain-valleys of the Sierra Nevada are a favourite range of the species. Besides, numerous "bear scrapes" have occurred to the migrating bands who have crossed the great plains and desert tracts that stretch from the Mississippi to the shores of the South Sea. Hundreds of stories of this animal, more or less true, have of late attained circulation through the columns of the press and the pages of the traveller's note-book, until the grizzly bear is becoming almost as much an object of interest as the elephant, the hippopotamus, or the king of beasts himself. Speaking seriously, he is a dangerous assailant. White hunters never attack him unless when mounted and well armed; and the Indians consider the killing a grizzly bear a feat equal to the scalping of a human foe. These never attempt to hunt him, unless when a large party is together; and the hunt is, among some tribes, preceded by a ceremonious feast and a bear-dance. It is often the lot of the solitary trapper to meet with this four-footed enemy, and the encounter is rated as equal to that with two hostile Indians. Of course, both Redwood and old Ike had met with more than one "bar scrape," and the latter was induced to relate one of his best.
