burrows or other safe refuge into which they would scamper, on 

 the slightest alarm, with a rapid succession of sharp chipping 

 noises. During the summer and early fall they are ever in evi- 

 dence and are not easily frightened. As fall comes on and seeds 

 and nuts mature, these interesting little animals become more ac- 

 tive and very busy laying up their winter stores, stopping now and 

 then to bask in the sun, their crammed cheek-pouches giving them 

 a comical, mump-like appearance. At this time of the year they 

 have a call or note quite different from the sharp chipping noise 

 usually heard in the summer, it being a succession of hollow cluck- 

 ing sounds, most interesting when heard at some distance through 

 the autumn woods. A little later, toward the last of October, when 

 frosts are frequent and the days are chill, they may be seen only 

 on those days that are bright and sunny, usually sitting in the sun 

 on the root of some old hollow tree, chipping merrily. Still later, 

 as cold days become the rule, only the brightest days tempt them 

 out; then they sit quietly where the sun shines warmest, chipping 

 not at all or only now and then very mildly.
