Excerpt from Observations and Experiments on the San Jose Scale Sulphur shows gain for Orchard I in 1907, on a plot the original infestation of which was degrees, and a gain of percent in Orchard II in 1911 on a plot the original infestation of which was degrees. It is true that the Rex plots in Orchard II agree less closely in the two years, the percent of 1911 being matched by a gain of 49 percent in 1907 but a glance at the grades of infesta. Tion explains the discrepancy, the 1907 plot having an average grade before treatment of degrees, and the 1911 plot a grade of degrees. We get a more obvious improvement, as a general rule, where the average infestation is the less. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The San Jose Scale: Its Occurrences in the United States With a Full Account of Its Life History and the Remedies to Be Used Against It Much that is printed here has already been published in one shape or another in Insect Life, and republished in experiment-station bulletins and agricultural newspapers, but most of the topics of importance have been considerably added to in this publication. The most com plete life history hitherto published, for example, is that given on pages 287 - 289, Volume VII, of Insect Life. Careful observations during an additional season have enabled us to make the present account much more complete. The chief work which remains to be done is remedial. The writers feel by no means satisfied that cheaper if not more efficacious washes will not be found. They will continue experimental work in this direc tion, and in this work they count upon the cooperation of all experiment station entomologists.

Excerpt from Experiments With Insecticides for the San Jose Scale It was the principal object of these experiments to test the ef feets of rains on the two washes used, but other important results appeared in the outcome besides those immediately aimed at. Counts of dead and living scales on the check trees not treated and on the experimental trees before treatment, showed a surprising percentage of half-grown scales already dead, the ratio of dead young to living scales varying on different trees and on different parts of the same tree from twenty-one per cent. To sixty-nine per cent. This fact had already been observed in other localities where our insecticide work was in progress, and had, indeed, been noticed and reported as early as 1898 by another assistant of the office, Mr. E. B. Forbes, engaged in distributing to infested trees in southern Illinois the spores of a fungus parasite of the San Jose scale. This Spontaneous death of many of the scales which might have been expected to pass the winter alive, was apparently due in great measure and in both instances to a severe drouth of the pre ceding year. Consistently with this explanation the dead scales were most abundant on trees worst affected by the drouth, and on parts of trees to which the flow of sap would naturally be least.

Excerpt from The San José Scale (Aspidiotus Perniciosus, Comst.) And Methods of Treatment This bulletin is written in response to a very urgent demand for information on the San J osé scale, as evinced by the hundreds of letters which come into the office of the Extension Department of the College every year' with questions regarding this insidious fruit pest and methods of destroying it or preventing its ravages. The bulletin is divided into two parts. The first part, in large type, is in the nature of a summary, and presents briefly the essentials in formulas. And directions for treatment of the scale for quick perusal and for those who do not care for a further study of the subject. With each of the statements in the summary, page references are given to the second part of the bulletin. The second part of the bulletin takes up a fuller discussion with an endeavor to present a history and description of the scale and methods of dealing with it in the light of present knowledge and practice such as the up-to-date Twentieth Century farmer is demand ing. The bulletin contains but little original material, except such general observations as have been made on the behavior of the scale under local conditions and the tabulation of losses as shown by in formation obtained through the circular sent out the past autumn to the names on the mailing list of the Rhode Island Experiment Station.
