THE GEIZZLY BEAR AND BISONS. Except Man, the Bison or American Buffalo has little to fear from any antagonist, for its great strength, courage and endurance overawe all Beasts of Prey, except, occasionally, a hungry Grizzly Bear. This Bear can sometimes overcome a solitary Buffalo which may become isolated from the herd. The episode which is illustrated in the picture is one of excitement among the most formidable animals which are found in valleys and foothills of the Rocky Mountain regions. The Grizzly Bear has attacked a Bison Calf which has become separated from the herd. The piteous wail of the dying Calf has brought the herd of Buffaloes to the scene and the Grizzly Bear must now reluctantly abandon his prey and seek safety in flight, or be killed, for he cannot overcome the attack of the herd of infuriated' beasts, although his running powers are sufficient to enable him to escape.
