Note : There is always a large hatch of these on Duck 

 Brook. One occurred when I was there with Dr. Alexander 

 and Mr. Harrison on June 23, 1935. I went up the brook 

 the afternoon before to see if the hatch was on and there 

 was not a single individual in sight. In 1934 it was on 

 Julv 1 and on June 16 in 1937.
