About one year later Glass appeared again, jubilant. At once he broke forth into eulogies of Christian; but one chapter would not be large enough to contain them. He had trained that bear, with outrageous ease and celerity, and hadimmediately taken him upon the stage as a professional jiu-jitsu wrestler. And really, the act was admirable. As a wrestler, the bear seemed almost as intelligent as the man. He knew the "left-hand half-nelson" as well as Glass, and he knew the following words, perfectly: "Right, left, half-nelson, strangle, head up, nose under arm, and hammer-lock." [Illustration with caption: THE WRESTLING BEAR "CHRISTIAN" AND HIS PARTNER] Glass declared that this bear was more intelligent than any lion, or any other trained animal ever seen by him. He was wise in many ways besides wrestling,--in his friendship with Glass, with other bears, with other men, and with a dog. _He obeyed all orders willingly,_ even permitting Glass to take his food away when he was eating; but he would not stand being punished with a whip or a stick! In response to that he would bite. However, he generously permitted himself to be _held down and choked, as a punishment,_ after which he would be very repentant, and would insist upon getting into his partner's lap,--to show his good will. Glass was enthusiastically certain that Christian could reason independently from cause to effect. He declared that his alertness of mind was so pronounced it was very rarely necessary to show him a second time how to do a given thing. Training an Adult Savage Monkey. Once we had a number of Japanese red-faced monkeys, and one of the surplus adult males had a temper as red as his face. Mr. Wormwood, an exhibitor of performing monkeys, wished to buy that animal; but I declined to sell it, on the ground that it would be impossible to train it. At that implied challenge the trainer perked up and insisted upon having that particular bad animal; so we yielded. He wished him for the special business of turning somersaults, because he had no tail to interfere with that performance. Two months later Mr. Wormwood appeared again. "Yes," he said, but not boastfully, "_I trained him;_ but I came mighty near to giving him up as a bad job. He was the hardest subject I ever tackled; but I conquered him at last, and now he is working all right." A really great number of different kinds of animals have been trained for stage performances, running the scale all the way up from fleas to elephants. It is easy to recall mice, rats, rabbits, squirrels, parrots, macaws, cockatoos, crows, chickens, geese, cats, pigs, dogs, monkeys, baboons, apes, bears, seals, sea-lions, walruses, kangaroos, horses, hippopotami and elephants. It is a large subject, and its many details are full of interest. It is impossible to discuss here all these species and breeds.
