54 ANIMAL INTELLIGENCE 



manner described, I kept them under observation for 

 the period during which they survived, viz., one for 

 about a month and the other for between two and 

 three months. From the first one of them seemed to 

 take more kindly to his new surroundings than the 

 other; one appeared shy and dull, while his fellow 

 seemed as happy as any Chipmunk might be. They 

 were captured in September, and it has often occurred 

 to me that their habit of hibernation had something to 

 do with the behaviour of the one, though we should 

 expect that, in such a matter, both would be equally or 

 considerably affected. The degree to which, while 

 retaining their original habits, the latter became 

 modified in confinement, furnished me with an interest- 

 ing study, and suggested many problems. My ex- 

 perience does not agree wholly with that of Audubon 

 and Bachmann, who say in their " Quadrupeds of 

 North America" : " We are doubtful whether this 

 species can at any time be perfectly tamed." The one 

 of my Chipmunks that survived longest became, in a 

 short time, so tame that he would eat from the hand, 

 and even looked to be fed in this way. True, any 

 noise, or any unusual movement, might startle the 

 creature, when he would make the quick dart away 

 so characteristic of the species in the wild state, but 

 from this he very quickly recovered, and the tendency 

 to be thus frightened grew less and less. The authors 

 referred to also state that " they appeared to have some 

 aversion to playing on a wheel, which is so favourite 

 an amusement of the true squirrels." 



This does not at all agree with my observations, 

 for though at first my Chipmunk was apt to be startled 

 when he found the revolver of his cage moving on his 

 entering it, he soon got used to it, and delighted in it as 

 much as any squirrel could in fact, he used it by 

 night and by day, manifesting an ability to control it
