"It sometimes happens," said the Doctor, "that the jaguar is seen in the water from a steamer on the river. A friend of mine was ascending the Amazon some years ago on one of the Brazilian boats. Just as they rounded a bend in the river the pilot saw a jaguar swimming from one bank to the other and nearly in mid-stream. The boat was turned in his direction; the jaguar increased his speed, but could not escape. The odds of steam against muscle proved too much for the muscle; the animal turned for the side whence he started, but the boat turned too and pressed him closely. Then he was forced out into the middle of the river again; a small boat was lowered, as it could follow his turnings much more readily than the unwieldy steamer. A few vigorous strokes of the oars brought the boat near him; a lasso was thrown over his head, and then he wheeled about and attacked his pursuers. "They had him at an advantage, as he could not sustain himself in the water and maintain a vigorous fight at the same time. Just as his paws touched the side of the boat he was killed by a bullet from a revolver; his body was towed to the steamer and taken on board, where the skin was removed and carefully preserved. He was one of the largest of his race, and estimated to be only an inch or two less than three feet high at the shoulder when standing erect. He could have slaughtered and dragged off an ox easily. The jaguar's method of killing horses or oxen is to spring on the back, and break the animal's neck by a single blow of his powerful paw." [Illustration: GAME FOR THE JAGUAR.] "The jaguar will dig in the sand for turtle's eggs," said Manuel, "and he will also kill and devour turtles of good size; he can scoop out their shells as easily as though he had all the implements of a skilful cook, and he will stand in the water, where he seizes fish with his paws and tosses them on shore. If captured when very young he can be made as docile as a kitten, but when he gets his growth and strength he is a dangerous pet. I had one once," continued the guide, "and didn't realize what he was until he one day came near eating up one of my friends while playing with him. I concluded he was not good to have about a family, and sold him to a collector of curiosities." Fred asked what the collector did with him. "I heard that he had a hard time with the beast," said Manuel. "He went down the Amazon, and was several months on the voyage. By the time he reached Para the animal was nearly full-grown, and though perfectly submissive was averse to familiarity on the part of strangers. He bit the hand of a passenger on one of the steamers, and it was necessary to shut him in a cage; this made him ill-natured, and he refused to be quiet except in the presence of his owner.
