He introduced a roomy shifting cage into Boma's compartment, fixed the drop door, and for many days served Boma's food and water in that cage only. For two weeks the ape eluded capture, but eventually the keeper caught him. At first Boma's rage and fear were boundless; but presently the idea dawned upon his mind that he was not to be killed immediately. D'Osta handed him excellent food and water, twice a day, spoke to him soothingly, and otherwise let him alone. Slowly Boma's manner changed. He learned that he was not to be hurt, nor even annoyed. Confidence in the men about him began to come to him. His first signs of friendliness were promptly met and cultivated. At the end of ten days, D'Osta opened the sliding door, and Boma walked out, a wiser and better ape. His bad temper and his fears were gone. He trusted his keeper, and cheerfully obeyed him. Strangest of all, he even suffered D'Osta to put a collar upon him, and chain him to the front bars to curb his too great playfulness while his cage was being cleaned. Boma's fear of man has never returned. Now, although he is big and dangerous, he is a perfectly normal ape. The Training of an Over-Age Bear. A bear-trainer-athlete and "bear-wrestler" named Jacob Glass once taught me a lesson that astounded me. It related to the training of a bear that I thought was too old to be trained. We had an Alaskan cinnamon bear, three years old, that had been christened "Christian," at Skagway, because it stood so much pestering without flying into rages, as the grizzly did. After a short time with us, the concrete floors of our bear dens reacted upon the soles of its feet so strangely and so seriously that we were forced to transfer the animal to a temporary cage that had a wooden floor. While I was wondering what to do with that bear, along came Mr. Glass, anxious and unhappy. "My wrestling bear has died on me," he said, "and I've got to get another. You have got one that I would like to buy from you. It's the one you call Christian." Very kindly I said, "That is a mighty fine bear, as to temper; but now he is entirely too old to train, and you couldn't do anything with him. He would be a loss to you." "I've looked him over, and I like his looks. I think I can train him all right. You let me have him, and I'll make a fine performer of him." "I know that you never can do it; but you may try him, and send him back when you fail." Thus ended the first lesson; and I was sure that in a month Mr. Glass would beg me to take back the untrainable animal.
