Four applications on the same variety on the adjoining plat (plat C) resulted in a gain in yield of only bushels over the check, doubtless because of the thin setting of blossoms on this plat, but per cent of the fruit examined from the sample areas was free from fireworm 14.—Spray-guD used in spraying experimental plats. Shows size of struaui of spray used, with medium-sized disk at full eapaeity. On the McFarlin variety (plat F) three applications gave a gain of bushels per acre over the untreated vines, per cent of the examined fruit being free from fireworm injury. Four applications (plat E) gave better results, a gain of bushels over the un- treated vines, per cent of the examined fruit being sound. The Thkee Types of Nozzees Compared as to Economy of Time and Material. With the Bordeaux outfit (fig. 12) it took about 1-|- hours to spray an acre, an average of 609 gallons being necessary for a thorough application. It was necessary to walk about 24 times across the acre, which was in the form of a square. With the mist outfit (fig. 13), it took about 1 hour to spray an acre, 438 being the average.
