The lion, the tiger, the hyena, et id omne genus, can not coëxist in the same country with civilization. Not indeed, as is generally supposed, on account of the climate, but specifically because when the man and the tiger are in the same arena the one or the other must go to the wall....At the present time the Indian tiger, where the wall of civilization is not around him, breaks freely from his jungle, pursuing the antelope and the deer up the slopes of the Himalayas to the line of perpetual snow; while the leopard, the panther, and the cheetah stop not even for the snow, but follow their prey into the fastnesses of Siberia.
