(With Plate 7 and 5 Text‐figures) Following a discussion of methods for the uniform application of insecticides for evaluation purposes, a description of a vertical spraying apparatus is given. The spraying procedure is described. By varying different factors and estimating the consequent variation in the replication of deposit the accuracy of the apparatus was determined. The main advantage of the present method lies in the possibility of accurate and quick readjustment of the nozzle by means of a calibrated adjusting nut and a fixed vertical pointer. The nozzle is constructed of stainless metals and is not easily damaged.
