A hole is cut through a bamboo stick at the end, and the ends of the wire are inserted. Just before the holes the stick is wrapped tightly with stout cord to prevent splitting. For the net he uses white silk—a very fine-mesh silk veiling. The handle of the net is of va- riable length and strength. For beating bushes it is necessary to have a very stout stick, hardly more than 2 feet long. For sweep- ing, the handle may be lighter and longer, 30 to 32 inches. For but- terflies and dragonflies a bamboo handle is very good and may be 3 or 4 feet in length. Longer handles may be useful in special cases, and may be fastened to the ordinary handle. Most dealers make a jointed handle, which is a great convenience in packing, and one- half is about the proper length for beating. The net may be of various materials. For butterflies a light net is the best; some thin material through which one can see the insect. Some use silk, or a silk gauze; some a material called "tarletan;".
