A man with less of the bulldog perseverance would not have succeeded, nor a man with less skill as an experimenter—less full of expedients. His first work seemed to point to success from a water-proofing of paris green, but the next season's spraying work showed this to be a failure, and paris green, which up to this time had everywhere been regarded as the standard remedy for codling moth, finally had to be discarded. Mr. Volck's work in 1904 consisted very largely in testing out all the brands of arsenicals on the market, other than paris green, and particularly the lead arsenates. Despite the serious burning of some orchards in 1903 the results in codling moth control so pleased the growers that a considerably larger acre- age was sprayed in 1904, and since most of this was with lead arsenate, and the season not particularly bad for burning, thej' became enthusiastic enough to spray about a third of the entire bearing acreage in 1905. The gradual extension of spraying is graphically shown in the accompanying chart. The spraying in 1905 was almost exclu- sively with Swift's arsenate, since that had proven best in the experiments of the previous year. The results obtained during this year were the most disap- pointing of the whole conflict. While the codling moth was well controlled the amount of burning was so large that the progress of spraying was entirely checked. For three years there was no appreciable increase in the number of acres sprayed. For this reason, in 1906, two more students were sent into the valley.
