These two forms of calcium arsenate were tested in the field in various ways. The Lucas materials showed indications of some advantages in dusting qualities and in adhesion to cotton in spite of rains. It appeared to be slightly more efficient in reducing the percentage of squares attacked by the boll weevil in the plats dusted with this material and in the yield of cotton secured from an average of the four treated plats. In cage toxicity tests where weevils were exposed for twenty-four hour periods on dusted plants, the Lucas material gave an average mortality of 58% for the six successive periods of 24-hours exposure while "standard brand" calcium arsenate gave an average of 38%. These results were from three series of tests.
