NATURE-STUDY REVIEW [14:7— Oct., 1918 



is usually a back stairway giving a quicker, more direct access to 

 the outside. 



The amount of earth which must be removed from such a 

 subterannean house is a good deal for so small an animal to 

 manage and one would suppose that traces of it at least would be 

 visible at the entrance. But not so. Every bit of it is carefully 

 carried away and the only way he could accomplish this is by 

 means of his pouches. 



To such a sun -loving merry creature as the chipmunk, it must 

 be a great change to live in the dark earth ; but since he is entirely 

 terrestrial in his feeding habits it is necessary that he should 

 hibernate while his food supply is covered with snow. 



Unlike many of the small hibernating mammals, the chipmunk 

 becomes only comfortably fat in the fall — his sleep is not so 

 profound and he frequently wakes up and partakes of his food 

 stores while waiting for spring. 



The chipmunk is one of the first signs of spring coming, out 

 sometimes in March and the first one to see his little striped form 

 slipping along the rail may feel that winter is over.
