Vredenburg BldiJ. ROCHESTER, N. Y. six weeks after the calyx spraying, although precocious moths can be found during blossoming time. Al- though there is considerable variation in dating the first and second sjjrayings owing to (luctuations in spring weather year after year, yet by the time of the second brood the seasons average up with remarkable consistency. For in- stance, during four years at North Yakima the first worms of the second brood have hatched on July 19th, which fixes that as the calendar date for the third spraying. Therefore spraying dates for the third and sub- sequent applications, once determined, can be relied on in the future. We have repeatedly had perfect re- sults when using one pound of jiaste arsenate of lead to every fifty gallons, and have even carried the dilution to one to seventy-live without lowering the efiicicncy of the spray. When the application is thorough two or more pounds to fifty gallons seem to gain nothing. Freciuently apples whitened with spray become excessively wormy. It is not a concentrated spray, but a careful, uniform, thin coating that counts. Indeed, theoretically an in- crease in concentration might produce a decrease in efficiency owing to the selective feeding habits of the newly- hatched worms. By the same reason- ing the poorer results following a com- bination spray can be accounted for, because the minute worms plausibly refuse to eat such unnatural and dis- tasteful materials as bordeaux spray, lime, sulphur preparations, tobacco, soai) or oils. By way of sununary con- clusion, the fight against the codling moth hinges on the calyx applicati
