The Indian Rhinoceros, (_Rhinoceros unicornis_).—A full-grown Indian Rhinoceros is one of the most wonderful of all living animals. It seems like a prehistoric monster, belonging to the days of the dinosaurs, rather than a creature of to-day; and the killing of so grand a creature solely for the sake of “sport,” and a stuffed head to hang upon a wall, is murder, no less. It is quite time that the most wonderful works of animated Nature should universally be recognized as safe from attack with the rifle and knife. So pronounced is the rarity of the great Indian Rhinoceros, it is a fact that for nearly fifteen years no living specimens came into the wild-animal market. At last, however, the persistence and industry of the renowned Carl Hagenbeck was rewarded by the capture, in 1906, of four young specimens, all of which reached Hamburg in May, 1907. One of the best specimens of the quartette was purchased for the New York Zoological Park, and is now living in the Park in the quarters prepared for him at the Elephant House. [Illustration: PYGMY HIPPOPOTAMI.] The Indian One-Horned Rhinoceros is the largest of all living rhinoceroses. A full-grown male is about 5 feet, 6 inches in shoulder height, and 10 feet 6 inches long from end of nose to root of tail. The length of the horn is not great, rarely exceeding 12 inches. The skin is very thick, and lies upon the animal in great rigid slabs which are divided by articulating areas of thinner skin. The Hippopotamus, (_Hippopotamus amphibius_), is more frequently seen in captivity than any of the large rhinoceroses, or the African elephant. In the lakes and large rivers of central East Africa it still exists in fair numbers, and still is killed for “sport.” Strange as it may seem, this very inert and usually lethargic monster can, under what it deems just provocation, become very angry, and even dangerous. Four years ago, in one of the rivers of Uganda, a hippopotamus not only overturned a boat, but killed one of its native occupants by biting him. The Hippopotamus breeds readily in captivity, even under poor conditions, and the supply for the zoological gardens of the world is chiefly maintained in that way. The fine male specimen exhibited in the Zoological Park was purchased from the Central Park Menagerie, for $3,000, and is a gift from Mr. Samuel Thorne. He was born on July 13, 1904. His weight on November 1, 1909, at five years of age, was 3,114 pounds; and he is growing rapidly.
