from the ground. Audubon and Bachman say,* ‘“‘We were unable to 
obtain any information in regard to the manner in which the Fox climbs 
trees, as he does not possess the retractile nails of the cat or the sharp 
claws of the squirrel, until we saw the animal in the act. At one time 
when we thus observed the fox, he first leaped on a low branch four 
or five feet from the ground, from whence he made his way upward by 
leaping cautiously and rather awkwardly from branch to branch, till 
he attained a secure position in the largest fork of a tree, where he 
stopped. On another occasion, he ascended in a manner of a bear, but 
with far greater celerity, by clasping the stem of a small pine. We 
have since been informed that the Fox also climbs trees occasionally 
by the aid of his claws, in the manner of a raccoon or a cat. During 
winter only about one fifth of the Foxes chased by hounds will take 
to a tree before they suffer themselves to be run down; but in summer, 
either from the warmth of the weather, causing them to be soon fatig- 
ued, or from the greater number being young animals, they seldom con- 
tinue on foot beyond thirty or forty minutes before they fly for protec- 
tion to a tree.”
