weak in body and unlikely to live long.

At the Zoological Park we have tested out the orang-utan's
susceptibility to training, and proven that the task is so simple
and easy that even amateurs can accomplish much in a short time.
Desiring that several of our orangs should perform in public, we
instructed the primate keepers to proceed along certain lines and
educate them to that idea. Naturally, the performance was laid out
to match our own possibilities. In a public park, where only a
very little time can be devoted to training, we do not linger long
over an animal that is either stupid or obstinate. Those which
cannot be trained easily and quickly are promptly set aside as
ineligible.

Without any great amount of labor, and with no real difficulty,
our orangs were trained to perform the following simple acts:

1. To sit at table, and eat and drink like humans. This involved
eating sliced bananas with a fork, pouring out milk from a teapot
into a teacup, drinking out of a teacup, drinking out of a beer-
bottle, using a toothpick, striking a match, lighting a cigarette,
smoking and spitting like a man.

2. To ride a tricycle, or bicycle.

3. To put on a pair of trousers, adjust the suspenders, put on a
sweater or coat, and a cap, reversing the whole operation after
the performance.

4. To drive nails with a hammer.
