TOIIPIDITY, 47 



son. In general, however, they retire from active life when 

 their food has become difficult to obtain, when the insects 

 have fled to their hiding places, and the cold has frozen in 

 the ground the roots and the seeds on which they subsist. 

 At die period of their reviviscence, the insects are again 

 sporting in the air, and the powers of vegetable life are ex- 

 erted in the various processes of germination and vegeta- 

 tion. 



Previous to their entrance into this state of lethargy, 

 these animals select a proper place, in general assume a

All the torpid animals retire to o, place of safety ^ where,

 to their habitations in such a manner, that it is more easy 

 to dig up the earth any where else, than in such parts 

 which they have thus fortified. The jumping mouse of 

 Canada seems to prepare itself for its winter torpidity in a
