The Minds and Manners of Wild Animals: A Book of Personal Observations

If there is too much delay in the response, he motions with his right paw, also, both arms working together. It is irresistible. At least 500 times has he thus appealed, and he will do it whenever a loaf of bread is held up as the price of an exhibition of his sign language. Of course Ivan thought this out himself, and put it into practice for a very definite purpose. Case 3. Ivan's Invention for Cracking Beef Bones. Ivan invented a scheme for cracking large beef bones, to get at the ultimate morsels of marrow. He stands erect on his hind feet, first holds the picked bone against his breast, then with his right paw he poises it very carefully upon the back of his left paw. When it is well balanced he flings it about ten feet straight up into the air. When it falls upon the concrete floor a sufficient number of times it breaks, and Ivan gets his well-earned reward. This same plan was pursued by Billy, another Alaskan brown bear. Case 4. A Bear's Ingenious Use of a Door. When Admiral is annoyed and chased disagreeably by either of his two cage-mates he runs into his sleeping-den, slams the steel door shut from the inside, and thus holds his tormentors completely at bay until it suits him to roll the door back again and come out. At night in winter when he goes to bed he almost always shuts the door tightly from within, and keeps it closed all night. He does not believe in sleeping- porches, nor wide-open windows in sleeping-quarters.
