BRAVER CUTTING DOWN A BLACK ASH AT NIGHT I THE FIRST PICTURE OF ITS KIND 



For two weeks the camera and flashlight faced this partly cut tree without result. Then 

 one night the beaver came, leaving his picture as well as the tree, for it stands today unfelled, 

 proof that a single animal does the work (see page 197). He was too frightened by the 

 flash to return that season.
