 an eye to protection and the skill with which the crafty builder con- 

 ceals the entrance, avoids making any apparent path to his home and

 kills the inmate by sucking its blood. 



Chipmunks are very sociable neighbors, delighting to chat to-

 when danger is approaching. The latter is done by peculiar chir- 

 rup-alarms which are passed along from one to another until the 

 whole community is on guard.
