 ping lightly over the snow a short distance ahead. We gave chase, 

 but the mouse escaped by running up the trunk of a smooth-barked 

 beech hard by. My friend, who was not aware of its climbing pro-

 ease and nimbleness as a squirrel, ascended the tree and disap- 

 peared in a knot-hole high among the branches. 



The White-footed Mouse does not hibernate. Except during the
