into L. A third time lie put bis left baud on 2k. straigbtened bis arm and 

 followed tbis action by thrusting bis right baud into L as before. He tbeu 

 went away from L. 



P. 7 to P. 10. No. 13 watched No. .5 carefully and drove her away from 

 the food, which be ate. He then went up to X and watched No. 5. When 

 she went near 2k be dashed for L. 



No. 5 was now removed and No. 13 was left alone in the cage. Not all 

 the food that No. 5 bad brought down bad been eaten, and No. 13 con- 

 tinued eating, going to L to get the seeds and climbing to X to eat tbem. 

 When be could find no more food be sat at L and scratched the edge of 

 the opening with his band. Then he grabbed 2k and pounded it against 

 the board ; taking 3k in bis right band and 2k in bis left, be pounded tbem 

 together ; afterward he did the same with 2k and Ik. He then went up to X 

 and perched for a moment, but almost immediately went to the floor and to L. 

 Thrusting his band in he searched for food and tlien looked into the opening 

 intently. Looking up, he took bold of 2k with his left hand and pounded 

 the board with it vigorously, then bit it and dropped it. Taking 2k in his 

 bands he went up to X, dropping the string as soon as be was settled on the 

 brace. His eyes turned at once to L and be went down to it and searched for 

 food; be picked up 2k in both liands and looked at it carefully; then be 

 pounded the board with it. Dropping it be went up to X, returning at once to 

 L; be grabbed 2k in bis luind, put it gently against Ik and dropped both of 

 tbem ; be returned to X, and. coming down to L, he did the same thing over 

 with 2k and Ik. He went up to X and tried to go up to 2t. but was pre- 

 vented. He then perched at A', looking at L for one minute. He was intent 

 on the getting of food at L. but he seemed puzzled. After looking intently at L 

 and the strings be went to the floor and to L. stopping to sit down and look 

 the string and opening all over. Then he again went up to A. 



Again No. 13 left his place at X and went to the door, pushing on it in an 

 effort to get out. Being unable to get out, be turned away from the door to 

 L and sat down in front of it. Quite slowly he looked it all over and, in the 

 same deliberate manner he looked up to 2k, took hold of it with his left hand 

 and gave a steady and vigorous pull. The food dropped to the bottom of 

 the chute and his right band shot into the opening and pulled it out. The 

 food was soon eaten and No. 13 immediately pulled the string again with 

 bis left band, getting the food in the same way as before. Without once leav- 

 ing bis place, he pulled the string six times, eating the food between the 

 pulls. While eating the food the third time, be put his band up to 2k 

 several times, but he did not pull bard enough to get the food. When his 

 food was gone, however, he pulled the string with a jei'k and the food 

 came. Repeatedly he dallied with the string in this manner while eating the 

 food, but he never failed to give a vigorous pull when the food was gone. 

 For fifteen minutes be sat before L. getting food repeatedly. He pulled the 

 string fourteen times in addition to the ones already mentioned, a total of 

 twenty times in all. The time from the removal of No. 5 until No. 13 got 

 food the first time was twelve minutes.
