WASHINGTON, May 9. — "The Orang-utan when he is captured young soon becomes friendly with man and attached to those who feed and care for him,” W. H. Sheak of Philadelphia, said at the meeting of the American Society of Mammaloogists here today. This monkey also has a very human-like smile and when the young animals play they smile often. But when the Orang-utan grows older he is inclined to become mean and cross, said Mr. Sheak. "The Orange-utan is almost if not altogether as intelligent as the chimpanzee,” declared Mr. Sheak. “But as he is less active he does not show up to as good advantage. Mr. Orang-utan spends much of his time sitting silent in one corner of his cage. He does not weep as easily as the chimpanzee nor laugh aloud as often.” “One orang-utan wanted a walnut that lay just beyond his reach outside his cage. He tried to roll some straw into a wand, but this was too much broken. After deliberating for some time, he took off a red sweater he was wearing, pushed it between the bars of the cage, dropped it over the nut and pulled the nut within reach. This same animal pushed his keeper toward a lantern that was turned too high, because he had previously been burned by one that took fire and explored.”
