For insects which live in the water, a special water net will be neces=ary; one with wider meshes so that it may be drawn readily thru the water. A special kind of collecting is that called "; In a meadow or pasture, especially if many flowers are in bloom, whip the net quickly back and forth over the tops of the weeds and grasses. You will be sure to catch a host of .small insects and spiders in this way. Do not collect the flying insects alone, but collect lar- vae, caterpillars, cocoons, chrysalides, nests, leaves and twigs bearing galls or showing the effects of insect attack, and all other specimens which illustrate the life of insects. The preservation of the collected specimens is simple, and easily learned. The insects are to be pinned up, i. e., each insect is to be mounted by thrusting a special kind ot slender pin (called an insect pin) thru the middle of that part of the body called the thorax, the part ot the body from which the wings arise. Beetles, only, are not pinned thru the middle of the thorax, but thru the right wing-cover close to the median line of the body. These insect pins must be bought of a dealer in nat- uralists' supplies, and can be 'r^fj had in various sizes. The sizes most commouty used are numbers i and 3 of the kind of pins called Klaeger .pins. (The dealer may not •^ — '~~ !-' ~—^^^~Zi^7^:' have the Klaeger pins, but a ti^ kind called Karlsbader; num- bers 3 and 5 are the size to Fig. 11. "Piuned-up" insect bu}' of this kind.) Thcsc pins cost 12 or 15 cents a hundred. The insects should be pushed up on the pin so that only one-third of the pin projects above the back of the specimen (fig. 11). Most insects need no further care than this simple pinning. Please note that these images are extracted from scanned page images that may have
