Subtracting $3.24, the expense of spraying, there remains a net profit of $13.68 per acre. THE PERU EXPERIMENT. This experiment was conducted by D. Clark, Peru, Clinton County, who made similar experiments for the Station. in 1904 and 1905. One field of four acres was sprayed four times and another of five acres five times. The four-acre field. was planted June 14 and 15, the other June 8. In both fields the variety was Green Mountain.. The sprayer was the same as that used in previous experiments; namely, an " Aroostook" potato sprayer which is drawn by two horses and covers six rows at each passage with one nozzle per row. The bordeaux used was of the usual 6-4-50 formula. About 25 gallons per acre were applied in each spraying. Water was obtained from a well near the smaller field and about 50 rods from the other one. The checks consisted of one unsprayed strip of three rows in the four-acre field and two unsprayed strips of three rows each in the five-acre field. In the four-acre field the check rows were treated once (July 31) with paris green in water, while on the sprayed portion of the field poison was used with the bordeaux in all four sprayings. In the five-acre field the checks received two applications of paris green in water for "bugs" while the sprayed rows received poison in all five sprayings. "Bugs" were plentiful and caused considerable injury in both fields. The check rows, not being properly protected, were more injured than the sprayed rows, so that a part of the difference in yield between the sprayed and unsprayed rows is due to "bugs...
