Passing the great fish-pond, which in summer is ornamented with swans and in winter is very popular for skating, we come to the piggery, a pretty building in blue-gray basalt covered with natural red tiles. Each pig has a roomy eating and drinking trough, and is kept clean and free from smell. The floors are on a slant, and the drainage is excellent. Here are wart-hogs, some European wild boars (huge animals), small peccaries, and the brilliantly-coloured red river-hog. Next door are the birds of prey. Their building contains fifteen large flying cages, the one in the middle being the largest. At both ends of the rows of cages are twenty smaller cages. The great flying cages contain trees and a brook of flowing water. There are huts for nests built into the walls. The small cages are built of stone with bars in the front; shrubs are put into each. There are two sorts of vultures, thirty species of hawks, and ten of owls. A bridge of stone close to the eagle rocks connects the old part of the Garden with that of the new. The street below has not been destroyed, doubtless owing to its historic character. From the bridge there is a beautiful view over the Mühlheim heath of the town beyond. Five-sixths of the space of the new part of the Garden is taken up by a large lawn covered with shrubs. At the end of this we come to the sea-lion grotto; the Garden guide calls it the _chef-d’œuvre_ of the Garden. From a large rockwork overgrown with moss and plants the water flows into a basin 15 yards long and 8 yards wide. At the back of the rock are huts for the seals. Retracing our steps, we come to the buffalo houses, three pretty, massive wood-block houses. In one are to be found no less than five American bisons; in the others are the Indian bison, the yak, the Cape buffalo, the gaur, the banting from Java, and the gayal. Going back over the bridge, we see to the right, rather hidden by bushes, a road leading to the antelope and elephant house, fitted with large outside pens with water-tanks. Here is to be seen a hippopotamus. Opposite the tank is a beaver enclosure; not far from the beaver house is the otter tank, with perpetually flowing water. The so-called elephant house is a plaster building in the Moorish style, with little towers and minarets. Going through folding-doors, we step into a wide hall. Near the door are the equidæ. The idea of uniting the antelopes and elephants is for the sake of economy. The pens are separated from each other by rolling doors. The animals are fed from the front. There are one African and two Indian elephants. The Indian female elephant has been in the Garden since 1872 and is now thirty-two years old; the African elephant, a young male, is eight years old--Mangasia he is called, after the famous Abyssinian Ras. The old hippo, which was born in Antwerp, is now dead, and has been replaced by a baby one. This little fellow tumbles about in his tank in a most amusing manner.
