In this net the main ring is of rounded iron wire on which anumber of brass rings are slipped. These must be but little larger [31] COLLECTING AND PRESERVING INSECTS FIG. 48.—Beating net, opened and attached to handle, with frameof same folded.

These little brass rings should not be more than 30 mm. or at most 40 mm., distant from each other, and to them the upper rim of the bag is sewed with very strong twine and is thus protected from wear and tear. The handle or stick of the net should be firmly and solidly attached to the ring and should be stout and not liable to break. I prefer a rather short stick, say not longer than two feet. I figure herewith the ring of a very convenient net for sweeping or beat-ing purposes. It has the advantage of being for sale on the market, and in fact is an ordinary fishing dip net of small size. Jt is hinged in three places, as shown in the figure, and folds into very small compass. When unfolded and brought together, it screwsinto a ferrule which may be attached to a cane or aspecial handle. The beating net
