ELECTRICITY TO KILL PESTS

Washington Man Demonstrates Value - of Now Method of Exterminating Many Injurious Insects. Spokane, Wash.—Electricity as sn agency to destroy the codling moth and other bug pests is the latest Innovation introduced in modern apple orcharding In the Spokane valley, where W. M. Frost of Opportunity, Wash., and J. C. Lawrence, a grower of Spokane, the other night gave what is declared to have been the first demonstration of its kind In the warld The test was made In a six-year-old orchard, and more than a score of sec-ond-brood moths and many green aphis were killed in a few momonts. The apparatus consists of a storage battery* to charge the incandescent light globes, each of six candle power, which are netted with fine steel wire, coated with copper and tin, alternately. Attracted by the bright lights in

the trees, to which the globes are carried at the ends of a covered wire, the moths fly against the netting, complete the electric circuit'and are instantly killed, the bodies falling Into a receptacle placed beneath the globe. Mr. Frost estimates that one battery to an acre of trees will keep the moths under control, thus eliminating the usual spraying and saving many dollars annually for help, equipment and fluid. He la now preparing to wire his orchard of ten acres, containing 700 trees, and several Neighbors who witnessed the initial test are doing likewise. It is reported that several thousand acres of hearing apple trees will be equipped with exterminators by next spring. If commercial electric light wires are extended to the orchard tracts, as they are in many of the valleys in Washington, Idahp, Oregon and Montana, the expense of batteries may he

saved by making direct cupuectlaaL. The cost of covering the globes with wire nets is a small item* and any electrician can do the work, • r : ■ ' *-v ' . .TOlv' - ./
