488 ANIMAL INTELLIGENCE 



pull the glazed leather cover off a trunk which was near him. 

 I pulled the trunk away, and when he found it was out of hiS' 

 reach he ran and pushed the marble towards the trunk in the 

 manner I have described, and when he knew his chain was 

 then sufficiently long to reach the trunk, he ran to the latter 

 and hastily resumed his destructive process. 



29th. I notice that nothing the person does who has hold 

 of his chain offends him. I mean, although he is furiously 

 angry at having anything taken away from him, he is not 

 at all angry if he is pulled away by his chain. If he is 

 trying to bite a person, and another person takes hold of hi& 

 chain behind him and so prerents his spring forward, he does 

 not turn to bite the person who has taken hold of his chain, as 

 a dog would do under similar circumstances, but quietly submits 

 to be thus held. He seems to look upon his confinement and 

 management by a chain as a natural law against which it is 

 useless to struggle. On the other hand, he seems to be quite- 

 aware of the place where his chain is fastened, and to know 

 that if he were clever enough to undo it he would be free. 

 After we found he could move about the marble slab of the- 

 washhand-stand in the way described, we had a ring sunk in 

 the floor to tie him to. The moment the chain was fastened to 

 that ^ he began to investigate its new connection, and continued 

 to do so for hours, passing the chain rapidly backward and for- 

 wards through the ring. When he found this did not loosen it,. 

 he began to hammer it and the ring also with all his strength,, 

 and this he continued to do for the rest of the day. 



30th. He still continues to work at the chain where it is 

 fastened to the ring. He passed the whole of the chain through 

 the ring so many times with his fingers that it became quite 

 blocked up in the ring, which made it very short, and it took 

 me a quarter of an hour to disentangle it. He was very much 

 interested in this process, sitting quietly beside me and watching 

 my fingers intently, sometimes gently pulling my fingers on one- 

 side in order to see better, and sometimes casting a quick in- 

 telligent glance into my face as if asking how I did it. After I 

 had disentangled and lengthened the chain he worked at it 

 again for hours, but took care not to twist it into the ring a 

 second time. 



31st. To day he hurt himself by getting one of his toes 

 caught in a hinge of the clothes-horse. He did not make any 



' January 14, 1881. The marble slab was left with him after the 

 chain had been fastened to the ring ; but since that time he has never- 

 attempted to move the marble.
