wall seemed to be alive with them. It was probably 
one of the rare chipmunk migrations, which, al- 
though denied by some naturalists, actually do occur. 
Chippy usually goes to bed in late October, and 
sleeps until late March. He takes with him a light 
lunch of nuts and seeds, in case he may wake up and 
be hungry during the long night. Moreover, these 
come in very handy along about breakfast-time, for 
when he gets up there is little to eat. Then, too, he is 
very busy during those early spring weeks. In the 
first place, he has to sing his spring song for hours. 
It is a loud, rolling ‘“Chuck-a-chuck-a-chuck,”’ al- 
most like a bird-song, and Chippy is very proud of it. 
Then, too, he has to find a suitable Miss Chipmunk 
and persuade her to become Mrs. Chipmunk, all of 
which takes a great deal of time. So the nuts which 
he stores up are probably intended rather for an 
early breakfast than a late supper. 
An Indian writer tells how the boys of his tribe 
used to take advantage of the chipmunk’s spring

dodge the blunt arrows of the boy-hunters. 
Besides his song the chipmunk has another high-

as he dives into his burrow. There are two phases
