 ground, nearly covering the short legs, and quite concealing the 

 three-inch tail. Under this thick blanket we should find, were it

 through which neither frost nor snow could find its way. 



Although we should not suspect it, either from the length of 

 limb or the general structure of the body, he is both quick and sure-

 inner and pointed hoof as well as an outer and rounded one, a pro- 

 vision which enables him to make rapid progress over ice and among 

 the steep and slippery rocks where he dwells.
