mountain feed the stream and supply the fish ponds with cool 
water. he stream is swollen after every freshet and then it 
gathers much silt, which gives a great deal of trouble by clogging 
the screens in the fish troughs. Of the insects collected from the 
stream within the meadow, only May fly nymphs of the genus 
Leptophlebia and caddis fly larvae of a number of wooden case 
building species were found in any considerable abundance.

New methods. Under this heading may be mentioned the 
use of two new pieces of apparatus that were designed for and 
first used in the field work of r905; a new form of trap lantern, 
and a water tent trap for capturing water insects at transformation. 
New form of trap lantern. The trap lanterns we used at 
Saranac Inn [described in N. Y. State Mus. Bul. 47, p.399] were 
efficient, but they were large and cumbersome, and difficult to carry 
from place to place. JI desired a smaller one that could be readily 
carried afield, and set up and run anywhere. So, I adopted for 
the lantern part of it a small acetylene bicycle lamp and made a 
small round trap of tin and celluloid to attach to its front, and 
hung out a leader in front of it, as shown in figure 3. The whole 
was attached to a light wooden arm, which could be quickly fas-
