As we retain these little captives against their will and treat them worse than slaves by keeping them in close confinement, we should at least try to amuse them. It is true that they do not have to toil; but it would be more humane to make them work in the open air than to confine them so closely and deprive them of every means of pleasure. As an act of humanity and simple justice, I would impress upon those who have the charge of these little pets the importance of keeping them supplied with toys. In this respect they are just like children. For a trifle one can furnish them with such toys as they need. It is absolutely cruel to keep these little creatures confined in solitude and deny them the simple pleasure they find in playing with a bell, a ball, or a few marbles. A trifling outlay in this way will very much prolong their lives. Monkeys are always happy if they have plenty to eat and something to play with. I recall no investment of mine which ever yielded a greater return in pleasure than one little pocket match-safe, costing twenty-five cents, which one evening I gave to Nellie to play with. I had put into it a small key to make it rattle, and also some bits of candy. She rattled the box and found much pleasure in the noise it made. I showed her how to press the spring in order to open the box; but her little black fingers were not strong enough to release the spring and make the lid fly open. However, she caught the idea and knew that the spring was the secret which held the box closed. When she found that she could not open it with her fingers, she tried it with her teeth. Failing in this, she turned to the wall, and standing upright on the top of her cage, she took the box in both hands and struck the spring against the wall until the lid flew open. She was perfectly delighted at the result, and for the hundredth time, at least, I closed the box for her to open it again. On the following day some friends came in to visit her. I gave her the match-safe to open. On this occasion she was in her cage, and through its meshes she could not reach the wall. She had nothing against which to strike the spring to force it open. After looking around her and striking the box a few times against the wires of her cage, she discovered a block of wood about six inches square. She took this and mounted her perch. Balancing the block on the perch, she held it with the left foot, while with the right foot she held to the perch. With her tail wound around the meshes of the cage to steady herself, she carefully adjusted the match-box in such a manner as to protect her fingers from the blow. Then she struck the spring against the block of wood and the lid flew open. She fairly screamed with delight and held up the box with pride. The lid was again closed in order that she might open it.
