In the spring of 1908 the writer applied an arsenate of lead spray (made at the rate of 1 pound of arsenate of lead in paste form to 12 gallons of water i to a plant bed that was seriously Infested with cut- worm-, with the result that all the cutworm- were killed before they l^^^A had done any appreciable addi- r- kj ^ "s^ tional injury t the plant-.
