The formula is pounds of sulfate, pounds of lime, fifty gallons of water; also two pounds of Paris green per acre are added. Each application is made in opposite directions, two such sprayings being called a double application. From the time the vines cover the ground, at the beginning of each double application all nozzles are directed to the right, then into the centers twice over and then to the left twice over. This plan requires three double applications, and the spray is directed against the plant from different posi- tions and angles ; at the completion of the sixth spraying, every part of the plant is copper-plated. The last week in September or the first week in October, while vines are still green, harvesting is J/ Fig. 757. Four-row potato sprayer. begun. A four-horse elevator digger is used. In 1906, the crop on eighteen acres was dug and picked up in six and one-half actual days, the total crop being 7,510 bushels, or 417 bushels to the acre. (Fourteen years previous, when Mr. Martin took the farm, the average yield was sixty bushels per acre. A good part of the above crop was hauled directly to the station and sold at foity cents ; bushels only were sold as low as thiity-eight cents). The heav- iest day's work in the harvesting in 1906 was as follows : Twenty-one helpers, little and big; three and three-fourths acres dug and picked up ; three two-horse rigs drew seventeen loads to cars one mile distant, comprising 1,011 crates; digging teams drew 283 crates on trucks to the barn ; at six o'clock there were left on wagons and in the field
