Spraying, Followed by Cyanid Fumigation Paris green as well as the copper of bordeaux mixture are readily soluble in solutions of cyanid. Copper com- pounds in general form complex sol- uble salts with cyanids and soluble copper is injurious to foliage. Trees sprayed with any form of copper should not subsequently be fumigated with cyanid without the lapse of at least one year on account of the solvent action of the cyanid on the cop|)er. So far as known there is no danger of this character from the use of llie other sprays. Need of Chemical Assistance in Study of Insecticides and Fungicides Dining the past two years an effort has been made to arrange a card index of the references in agricultural and chemical literature to insecticides and fungicides and allied topics. As a re- sult many thousands of cards have been collected. Hut in this collection sur- prisingly few cards are found refer- ring to articles which discuss the chemical composition of insecticides or their toxic action upon parasites and the hosts of parasites. The number of references to articles on spraying ex- periments, when, how and what to spray, etc., is very large. This work has been done mostly by the entomolo- gist, the plant pathologist and the hor- ticulturist, whose training and view- points are not chemical. The effect of remedies upon parasites and host has been carefully observed and t
