To use the net in water sweep the water plants as quickly as possible. In running streams overturn stones, holding the net just below them with the mouth up stream. An old dipper made into a sieve by perforating, the bottom with an awl is a good utensil for collecting water insects. The Killing Bottle, Fig. 2.
