4 FIKLD AND FOREST. 



minute yellow perch, associated with little sunfish, tangled in among 

 the water-plants, active as their strength permitted and darting vora- 

 ciously at almost invisible specks that seemed to serve them for food. 

 In the immediate neighborhood of the nest I have seen many hundreds 

 of such little perch.

 nary spring water, having some current, and the bed of the stream at 

 least partly covered with vegetation, is about such a locality as best 

 suits this fish.
