twice aud then jumped from the rope to the wire. Then he climbed the 

 rope, opened the door by pushing on it with his teeth as No. 3 had done, 

 and got food. Next he tried to climb the post in the corner, and then 

 ran up the rope again and got the food. During the next ten minutes he 

 climbed the rope twelve times, getting food most of the times. 



Summary of Behavior of No. 2 in the Rope Experiment. 

 No. 2 during a long series of preliminary trials did not climb the rope 

 nor pay any attention to it or to the food door. During the first Imitation 

 tests he was not attentive to No. 3, but gradually became so as he saw 

 him getting food, and in the last test his attention was riveted on No. 3 

 during the whole of the time No. 3 was in the cage. His learning to do 

 what No. 3 did was also a gradual process. When his attention was 

 directed to the food door his first effort to get to it was by climbing the 

 wire front of the cage. His next step was to learn to bear a portion of 

 his weight on the rope. When he got food from No. 3 there was a notice- 

 able increase in his apparent desire to get to the door. The stimulation 

 seemed to Increase steadily until finally it forced him to leap to the rope 

 and back to the wire and then to climb the rope from the floor. Once on 

 the rope, he repeated exactly the act of No. 3 and got food in the same way.

C. Behavior of No. If. 



Preliminary tria/*-.— First trial. No. 4 spent the first few minutes on the 

 floor picking over nut hulls. Then she became very active about the cage. 

 She climbed the rope and investigated the top of the cage and the cracks 

 between the boards. She spent the most of the remaining time on the floor. 



Second trial. On the second day No. 4 spent most of the time on the 

 floor swaying back and forth before the door. Nothing inside seemed to 

 interest her and she wanted to get out. Twice she climbed the wire slowly, 

 but paid no attention to the rope. 



Third trial. On the third day No. 4 was not so active as usual and 

 perched on the brace most of the time. She gave no attention to the rope.
