The monkey house is also found in front of the bear pit. This is the most attractive and popular house in the Garden. A young orang-outang, however, has monopolized most attention in the new aviary. The baboons, macaques, etc., will soon be placed in a new house, which will have more light from above, and there will be out-of-door cages. The capuchin seems to live out of doors all the year round. In the monkey house are different sorts of lemurs, white rats and mice, and the hamsters, which live in glass cases. One of the baboons has been for years in the Garden; he has learnt to dance, and will turn round as often as he is told. We leave the monkey house, built in pleasing Indian style, and come to the rodents’ grottoes and squirrel house. Here are porcupines and hystrices. The small rodents of the squirrel family live with the marmots or mountain-rats, and are to be seen close to the grottoes. This place is built of stone and iron to resist the sharp teeth of these gnawing animals. The carpincho (_Hydrochærus capybara_) is in an enclosure close by behind the monkey house. This animal is the largest of the rodents, being 4 feet long and weighing 98 pounds. Here also is a very fine collection of geese. Passing the pretty little house of the Director, we come to the splendid and imposing new aviary; here are all kinds of foreign birds, such as paroquets, etc. The four corners are marked by towers. There are outside cages, and the house is well built and free from draughts. On the south-west side of the house is a large open cage with a spring of water in it, containing wading birds, the ibises, and shore birds, such as oyster-catchers and plovers. Ladders lead up to the roosting-boxes. Each outside cage is provided with a good bath. All the birds are well labelled on the cages, and there are pictures of several of them. [Illustration: STORKS.

The Cologne aviary surpasses that of Berlin. The cages get their light from the front as well as from above; by this means you see the proper colours of the birds, and not merely their silhouettes. There are plenty of trees and plants for the enjoyment of the birds as well as for the pleasure of the visitors. These plants help to improve the air.
