Between the squirrels and the mink family the difference is as much a matter of disposition as of structure. The mink is the evil genius of the place. His character has written itself in his physiognomy, glitters in his eye and shows itself in the serpentine motion of his head. His silence speaks. But his presence is agreeable in a way, for it is a touch of that savage nature we do not otherwise get without going back into the wilderness. A squirrel reveals his candor in his inquisitiveness and in his noisy ways; curiosity gets the better of his fears. These psychologic differences are as marked with animals as with men. I once surprised the weasel in this glen, with a young robin in her mouth which she had just taken from the nest and was carrying home for her family. She dropped the bird when I threw a stone, whereupon I stood by the dead robin and waited, anticipating her return, for I knew the weasel's boldness of old. Almost immediately the sinister-looking creature poked her head from the bushes and, without hesitation, approached and seized the bird where it lay between my feet. Another stone caused her to drop it again before she had gone far. This time I moved the robin some little distance away and stood beside it as before. Soon the weasel reappeared, and going to the spot where she had last dropped it, became visibly excited on finding it gone. She then began rapidly following the scent, like a hound, and at length by a circuitous course, approached, and again took the bird from under my feet. Almost every fine day in autumn the woodchuck is to be met. He emerges from the bushes with deliberation and ambles out into the open where there is a little clover to tempt him, his tawny legs showing in strong contrast with his grayish back and scraggly black tail. His enjoyment is evident; the sun feels good to him. He is a chilly body, and, like the snakes, cannot get any too much warmth. Now he sits upon his haunches and takes a deliberate survey, then pokes some greens into his mouth with his forepaws. If his sharp ears bring him no suspicious sound, he drops upon all fours and goes to browsing again.
