I reached the scene just as he finished tearing both ends free. I saw him bend the steel panel inward, crush it down with his thousand pounds of weight, and dash through the yawning hole into his rival's arena.

Then ensued a great battle. The two huge bears rose high on their hind legs, fiercely struck out with their front paws, and fought mouth to mouth, always aiming to grip the throat. They bit each other's cheeks but no serious injuries were inflicted, and very soon by the vigorous use of pick-handles the two bear keepers drove the fighters apart.

Case 2. Ivan's Begging Scheme. Ivan came from Alaska when a small cub and he has long been the star boarder at the Bear Dens. He is the most good-natured bear that we have, and he has many thoughts. Having observed the high arm motion that a keeper makes in throwing loaves of bread over the top of the nine-foot cage work, Ivan adopted that motion as part of his sign language when food is in sight outside. He stands up high, like a man, and with his left arm he motions, just as the keepers do. Again and again he waves his mighty arm, coaxingly, suggestively, and it says as plain as print: "Come on! Throw it in! Throw it!"

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.

Case 5. Admiral Will Not Tolerate White Boots. Recently our bear keepers have found that Admiral has violent objections to boots of white rubber. Keeper Schmidt purchased a pair, to take the place of his old black ones, but when he first wore them into the den for washing the floor the bear flew at him so quickly and so savagely that he had all he could do to make a safe exit. A second trial having resulted similarly, he gave the boots a coat of black paint. But one coat was not wholly satisfactory to Admiral. He saw the hated white through the one coat of black, promptly registered "disapproval," and the patient keeper was forced to add another coat of black. After that the new boots were approved.

Case 6. The Mystery of Death. Once upon a time we had a Japanese black bear named Jappie, quartered in a den with a Himalayan black bear,—the species with long, black side-whiskers and a white tip to its chin. The Japanese bear was about one-third smaller than the Himalayan black.

One night the Japanese bear died, and in the morning the keepers found it lying on the level concrete top of the sleeping dens.

At once they went in to remove the body; but the Himalayan black bear angrily refused to permit them to touch it. For half an hour the men made one effort after another to coax, or entice or to drive the guardian bear away from the dead body, but in vain. When I reached the strange and uncanny scene, the guardian bear was in a great rage. It took a position across the limp body, and from that it fiercely refused to move or to be driven. As an experiment we threw in a lot of leaves, and the guardian promptly raked them over the dead one and stood pat.

We procured a long pole, and from a safe place on the top of the nearest overhang, a keeper tried to prod or push away the guardian of the dead. The living one snarled, roared, and with savage vigor bit the end of the pole. By the time the bear was finally enticed with food down to the front of the den, and the body removed, seven hours had elapsed.
