Formula (b)—15 pounds of iron sulphate to 100 gallons. Formula (c)—lYz. pounds of iron sulphate to 100 gallons. Formula (d)—5 pounds of iron sulphate to 100 gallons. First spraying, March 27, 1908; cool and cloudy weather; formula (a); applied to four full bearing White Pearmain trees, three young Bellflower trees, two full bearing pear trees and 16 full bearing Newtown trees; amount used, 200 gal- lons.

First spraying, March 27, 1908; cool and cloudy weather; formula (a); applied to four full bearing White Pearmain trees, three young Bellflower trees, two full bearing pear trees and 16 full bearing Newtown trees; amount used, 200 gal- lons. Formula (b) applied to eight-year- old Newtowns; amount used, 100 gallons. The apple trees were not in bloom, but the blossom buds were unfolding, and the White Winter Pearmains had con- siderable foliage. One pear tree was in bloom and the other just ready to expand its blossoms. Second spraying, April 28, 1908; clear and warm weather; formula (c) applied to the same trees receiving the first spraying. Arsenate of lead was used in the mixture applied to the bearing trees at the rate of six pounds to 100 gallons. Amount of spray used, 300 gallons. Young Newtowns received 100 gallons without arsenate of lead. All the trees were past blooming, and the calyx cups of the apples were rapidly closing. Foli- age had now become abundant. Third spraying, June 3, 1908; weather clear, temperature moderate, light wind; formula (a) applied to the same trees receiving the other sprayings. The 300 gallons applied to the bearing trees con- tained arsenate of lead at the rate of four pounds to 100 gallons. The trees were all in heavy foliage, apples size of wal- nuts and larger. Fourth spraying, August 1, 1908; warm and cloudy weather; formula (d) applied to one-half of the trees receiving the other sprayings, each variety. The pear trees were omitted. Arsenate of lead was used in the mixture at the rate of six pounds to the 100 gallons, and those trees not receiving the iron sulphide application w
