 distracted and she did not climb. Later she climbed the front of the cage and 

 clinging with her feet and one hand, she allowed her body, head and other 

 arm to swing away from the cage toward the chute. This conduct came 

 nearest to suggesting the influence of No. I2's behavior of any during the 

 whole of the experiment. 



In all the later tests. No. 1 was more or less attentive to No. 2 and usually 

 got food when he pulled the string, but when he was removed she became 

 quite indifferent to the chute and took her leisure about the cage as if the 

 means of getting food was not present.

 opportunities to see No. 2 perform the operation and had profited frequently 

 by getting food. It then seemed certain that she would not learn to work the 

 device from seeing No. 2 do it. A stick, two inches wide, was placed from the 

 wire front of the cage to the chute. Within eight minutes, No. 1 had 

 climbed the side of the cage, had walked on the stick to the chute, had swung 

 down and thrusting her hand up the chute had opened the door. The 

 stick was then removed while No. 1 was on the floor. When her 

 food was eaten she became very active, making long leaps all about
