THE INSECT DRIFT OF LAKE SHORES. 



BY JAMES G. NEEDHAM, ITHACA, N.Y. 



During the summer of 1906, while still living in Lake Forest, 

 Illinois, in a pleasant cottage near to the shore of Lake Michigan, 

 I spent all my spare time upon the beach studying the insect ac- 

 cumulations of the shore-line, and trying to settle some of the 

 questions raised by my earlier observations (1900-1904). I visited 

 the beach nearly every day, and collected insects from the drift- 

 line whenever there were any deposited there. Through early and 

 late summer I merely collected when the collecting was good; but 

 during the month of August I made daily careful observations on 

 the insects at the shore-line, and on accompanying conditions of 

 wind, waves and weather. As often happens, I settled a few of 

 my questions and raised many new ones. After waiting ten years 



April. 1917
