We next come to the llama house, which includes specimens of guanaco and vicuna, the llama and alpaca. The reindeer enclosure follows. Behind this, again, are the moufflon and chamois rocks; a grotto cut out of the rock shelters the goats from Chili. Below the rock are lodged the graceful Indian antelopes. Between the rock and the aquarium is a construction with a deep basin, in which live the otters and seals. The otters, which were presented in 1891, are very tame. At the word of command they hop up to the top of a rock and take headers into the water. Opposite the otters’ tank is the cow house, holding forty cows, the little dairy at the side being much frequented during summer, when as many as a thousand glasses of milk are sold in a day. Close by the dairy is a picturesque enclosure of lawn and rockwork, inhabited by a herd of over twenty black buck of all ages. It was an amusing sight to watch them frisking and scampering about after the manner of the springbock of Africa. The aquarium, situated on the right beyond the dairy, contains ten large tanks of sea-water and four tanks of fresh-water. These basins are made of slate, with one side of glass. They receive light only from above, and in them are to be seen the octopus, shrimps, anemones, soles and plaice. Many of the fish grow tame to a remarkable degree, and know their keeper well. At the end of the aquarium is the fish-culture pavilion, in which one sees in transparent tanks a very complete collection of fresh-water fish and the most perfect apparatus in connection with fish culture. Every year the establishment incubates a considerable number of salmon spawn. Visitors can follow the operations of artificial fertilization of several species of trout, including the American rainbow trout. After the aquarium, in front of the concert kiosk, we find the restaurant, where we can have refreshments at fixed prices under large trees. [Illustration: HERD OF BLACKBUCK, JARDIN D’ACCLIMATATION, PARIS.] Facing the aquarium is a large glass enclosure surrounding the antelope house, in which can be seen the Indian nylgai, which breeds well; the eland, looking amongst the trees as if it was in its native haunts; the gnu, which looks half ox, half horse; the _Oryx beisa_ from Kordofan; a gazelle from the Soudan. And then comes a surprise, for in the same pen with several Patagonian cavies are no less than four hartebeests, one of which was born in the Gardens, August 15, 1901. Next we come to the deer house, with the wapiti from America, the axis deer from Siam, Père David’s deer, and others. On the other side of the main drive, and opposite the deer, is a large dog-kennel, containing dogs of every description. Here a large exhibition has been held every year since 1863, and dogs can be bought at fixed prices.
