would unite with the alkali and the 

 nicotine would be set free. In this 

 form the alkaloid would be just as 

 active and probably more so, but would 

 be more liable to lose by volatilization. 

 .\cids would have no effect upon the

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 this or 

 that procedure has been reconnnended 

 or condemneii as the result of practical 

 experiences. In man.\- cases the reasons
