War on the house fly. — Try a season's campaign against flies and see to what extent you can reduce their number. If you live on the farm and have no close neighbors, you can fight the war alone, but in a village or town the cooperation of the whole community must be secured. Some cities as large as Cleveland, Ohio, have conducted such a campaign and report a sweeping victory. The operations must follow. SmE View and Cross-section op Fly Trap along these lines: "In the early spring clean up all refuse heaps, filth of all kinds, manure pUes, garbage heaps, old cans, trash of all sorts, and abolish as far as possible open vaults and earth closets. Screens should be used freely on all doors and windows. The prompt disposal of garbage should be arranged for and swill barrels and garbage cans should be tightly closed. Use .some form of fly trap with the proper bait early, and continuously; place it where it will do the most ; (From circular No. 26, State Entomologist of Minnesota.) II. Ants. — Nests of ants are often found under boards and stones and in the ground near plants. Others make little mounds of earth, "ant hills,'' that are several inches high and several feet across. They are especially interesting. Note the openings leading down into the ground; see whether the ants go in and out of these. Are they carrying things ? With a stick dig up a portion of the mound; how do the ants behave now? Do you see some white objects looking like small grains of rice ? These are young ants in the pupa stage. The pupae themselves are in these tiny white bags or cocoons. Note the care taken of these. Please
