chute ; catching the rung of the chute hi his hands he drew himself over to 

 it ; fiuding himself above the end of the chute he tried to let his body dovpn, 

 tirst ou one side and theu on the other, until lu the most awkward manner 

 he managed to get near enough to the end to thrust a hand up the inside 

 far enough to reach the string. At once he pulled and the food came tum- 

 bling down on his chest and to the floor. Dropping to the floor he picked up 

 the food and ate it. The time from the removal of No. 4 was 40 seconds. 



Within one minute he climbed the front wire, reached the chute, and got food 

 in the same manner. On reaching the chute the third time he did not pull 

 himself above the end, but holding to the rung with his hands he dropped 

 his body below the end and placing his feet agaiiist the back of the 

 cage steadied himself while he thrust the free hand up inside and pulled 

 the string. Time : 40 seconds. From this time on No. 13 repeated the per- 

 formance as rapidly as his food was eaten. Within ten minutes he had gotten 

 food eleven times and had eaten it all. From the moment he was released in 

 the cage he seemed bent ou getting the food. In his efforts, he made but one 

 useless movement, namely, when he drew back from the chute after first 

 putting his hands on it. This, however, did not indicate a wavering from 

 the end in view. It was merely a drawing back for the renewed effort which 

 he immediately made. 



Sninmarij of Behavior of No. 13 in Chute Experiment B. 



During the preliminary trials No. 13 was exceedingly active, but at the 

 end of the time he had made no progress toward a solution of the problem. 

 He had gone to the chute, but there was no evidence that this was more than 

 a random act in his movements about the cage. He did not notice the end 

 of the chute and in no way did he seem to connect the chute with getting 

 food. During his last trial he was quiet much of the time. 



After his preliminary trials he saw No. 4 getting food at the end of 

 the chute five times. He was confined in an observation box so that he 

 could not follow No. 4 about. He did not get any food and he experienced the 

 result in no way. However, when he was released in the cage his behavior 

 was strikingly different from his liehavior during any of his preliminary trials. 

 He went almost directly to the place where he had seen No. 4 get food and 

 within two-thirds of a minute he had gotten food for himself by doing 

 essentially the same act No. 4 had done while he was watching her.
