In a short time the Terror had whipped and thoroughly cowed Bruno and Jappie. Next he tackled Ben; but Ben's great bulk was too much for him. Finally he devoted a lot of time to bullying and reviling _through the bars_ a big but good-natured cinnamon bear, named Bob, who lived in the next den. In all his life up to that time, Bob had had only one fight. Tommy's treatment of Bob was so irritating to everybody that it was much remarked upon; and presently we learned how Bob felt about it. One morning while doing the cage work, the keeper walked through the partition gate from Bob's den into Tommy's. He slammed the iron gate behind him, as usual, but this time the latch did not catch as usual. In a moment Bob became aware of this unstable condition. Very innocently he sauntered up to the gate, pushed it open, and walked through into the next den. The keeper was then twenty feet away, but a warning cry from without set him in motion to stop the intruder.

Himalayan bear jealously guarding the body of a dead cage-mate.] Having no club to face, Bob quietly ignored the keeper's broom. Paying not the slightest attention to the three inoffensive bears, Bob fixed his gaze on the Terror, at the far end of the den, then made straight for him. Tommy made a feeble attempt at defense, but Bob seized him by the back, bit him, and savagely shook him as a terrier shakes a rat. The Terror yelled lustily "Murder! Murder! Help!" but none of the other bears made a move for his defense. Bob was there to give Tommy the punishment that was due him for his general meanness and his insulting behavior. The horrified keeper secured his pike-pole, with a stout spike set in the end for defense, and drove the spike into Bob's shoulder. Bob went right on killing the Terror. Again the keeper drove in his goad, and blood flowed freely; but Bob paid not the slightest attention to this severe punishment. Then the keeper began to beat the cinnamon over the nose; and that made him yield. He gave the Terror a parting shake, let him go, and with a bloody shoulder deliberately walked out of that den and into his own. The punishment of the Terror went to the full limit, and we think all those bears approved it. In a few hours he died of his injuries. Case 8. The Grizzly Bear and the String. One of the best illustrations I know of the keenness and originality of a wild bear's mind and senses, is found in Mr. W. H. Wright's account of the grizzly bear he did not catch with an elk bait and two set guns, in the Bitter Root Mountains. This story is related in Chapter VI.
