150 GORILLAS AND CHIMPANZEES 



After a few minutes he returned with the gourd 

 about half filled with water. In carrying the vessel 

 he held it by the neck, but this deprived him of the 

 use of one hand. He waddled along on his feet, 

 using the other hand, but now and then would set 

 the gourd on the ground, still holding to it, and 

 using it something after the manner of a short stick. 

 On delivering the gourd of water to his master, he 

 gave evidence of knowing that he had done a clever 

 thing. I expressed a desire to see him fill the gourd 

 at the spring. The water was then emptied out, 

 and the gourd again given to him. On this occasion 

 we followed him to the place where he got the water. 

 On arriving, he leaned over the spring and pressed 

 the gourd into the water, but the mouth of it was 

 turned down so that the water could not flow into it. 

 As he lifted the gourd out, it turned to one side and 

 a small quantity flowed into it. He repeated the act 

 a number of times, and seemed to know how it 

 ought to be done, although he was very awkward in 

 doing it. Whenever the water in the mouth of the 

 gourd would bubble, he would dip it back again and 

 was evidently aware that it was not filled. Finally, 

 raising the vessel, he turned and offered it to his 

 master, who declined to relieve him of it. We 

 turned to go back into the town, and the ape followed 

 us with the gourd, but all the way along continued 

 to mutter a sound of complaint. 



He next sent him into the edge of the forest to 

 bring firewood. He was only gone a few minutes 

 when he returned with a small branch of dead wood
