CIRCUIT OF THE SUMMER HILLS 



A buttemut-tree stands across the road in front 

 of Woodchuck Lodge. One season the red squirrels 

 stored the butternuts in the wall of one of the upper

 character of much animal behavior, the extent to 

 which their lives flow in fixed channels, was well 

 seen in the behavior of this squirrel. His procedure

 one hundred feet, was as definite and regular as the 

 movement of a piece of machinery.' He would rush 

 up and over the roof of the house with a nut in his 

 mouth, by those sharp, spasmodic sallies so charac-

 ten feet away, up it a few feet to make an observa-
