 side a quarter of a mile distant so short a time

 slide, through canal and basin, was now piled on 

 the bottom of this pond? I waded out into the 

 water, prodded about with a pole, and found sev- 

 eral smaller logs. Dragging one of these to the 

 surface, I found there were three notches in it. 



Evidently these heavy green tree cuttings had 

 been sunk to the bottom simply by the piling of 

 other similar cuttings upon them. With this 

 heavy material in the still water a slight contact 

 with the bottom would prevent the drifting of ac-

 formed. However, in deep or swift water I have 

 noticed that an anchorage for the first few pieces 

 was secured by placing these upon the lower slope

Scores of aspens were felled in the grove where 

 the notched ones were. They were trimmed, cut
