260 EXPERIMENT STATION RECORD. 



A few facts about insects, R. W. Doane ( Washington Sta. Bui. 27, pp. 52, Jigs. 69).— 

 This bulletin forms a popular treatise on the subject of insects, its purpose being to 

 give the average farmer or orchardist, who has little or no time to devote to the 

 study of insects, some idea as to how they grow and breed, what changes they undergo, 

 how they are classified, the more common of the different orders of insects, mites, 

 spiders, and ticks, the natural enemies of insects (which are treated under the head 

 of beneficial insects), and of various remedies and preventive measures that the 

 farmer may employ. Under the head of preventive measures, high cultivation, clean 

 culture, crop rotation, protection of plants by screens, etc., and late plowing are 

 mentioned. The active measures noted are hand picking, trapping, and the use of 

 external irritants and insect poisons. Directions are given for using Paris green 

 mixtures, kerosene emulsion, the sulphur, salt, and lime wash, resin wash, whale-oil 

 soap, white hellebore, tobacco, carbon bisulphid, and pyrethrum.
