SHEAK — INTELLIGENCE OF THE ORANG-UTAN

them, they would hurry after him, using their long arms as a man 
would use a pair of crutches, but often putting their heads to the ground 
and turning a somersault in their efforts to overtake their human 
friend. I have also seen them sit at table and use knife, fork, and spoon 
in eating, and drink out of an opaque bottle, looking repeatedly down 
the neck to see how much of the delectable fluid might be left. 
A two-year old baby orang which the Edwards Brothers had on 
exhibition in New York City in 1908, was very timid and much afraid 
of our large chimpanzee. The chimpamzee liked to tease the little 
fellow, because she saw he was afraid of her. When she would stamp 
her foot and threaten him, he would run to me and throw his arms 
about my neck, plainly imploring my protection from the great black, 
ugly beast, which he doubtless thought her to be. 
Though the orang may sit quietly in a corner of his cage, his beau- 
tiful brown eyes see everything about him. Indeed I have found 
him a very keen observer. One day I was standing in front of the 
cage of the orang with the Lambrigger Zoo, already referred to, when 
he came over near me, put his arm out between the bars, and went to 
examining something on my shoulder. On investigation I found there 
was a tiny knot, not larger than the head of a small pin, in the thread 
of the seam in my coat. I had not noticed it previously, but his eyes 
had caught it from the back of the cage and he was trying to get it. 
The orang-utan does not laugh aloud as often as the chimpanzee, but 
he has a smile that is strikingly human-like. When two young orangs 
are kept together, they become quite playful, romp and chase each 
other about, but in a more sedate and deliberate way, and not with the 
frantic haste and daring so characteristic of the chimpanzee. When 
thus engaged at play there is often a pronounced and joyous smile on 
their beaming faces. Now and then there may be a low chuckle, but 
not often. 
As already noted, they often become much attached to their keeper. 
They are also devoted to their own kind, and will often fight for each 
other, and especially their young. They will sometimes make pets of 
other animals, as cats, dogs, and rabbits. I once knew an orang that 
became much attached to a young pig-tail monkey. They spent much 
time together, the pig-tail usually sleeping in the ape’s arms. The 
orang was very affectionate, often fondling and caressing his little 
pet, and showing great patience, for the pig-tail was quarrelsome and 
vindictive, and often resented the familiarity of his fond foster father.
