addition of trouble or expense. The same holds true for a combination 

 of Bordeaux mixture with an arsenical for the apple scab and tlie cod- 

 ling moth, and many other illustrations will at once suggest themselves. 



Mr. Smith asked if the effect of conibiniug ammouiacal salts with 

 arsenate of lead had been tried, and was informed that no such experi- 

 ments had been conducted. 



The subject of insecticides was continued in the following j)aper by

SOME OBSERVATIONS ON NEW AND OLD INSECTICIDES AND 

 THEIR COMBINATION WITH FUNGICIDES. 



By B. T. Galloway, Washington, D. C. 



In the course of sundry investigations made during the past six to 

 eight years I have prepared and used a number of compounds with a 

 view of testing them as insecticides and fungicides. As yet but few 

 of the preparations have been made public, owing to the fact that 

 many points in connection with them still remain unsettled. I should 

 prefer to allow the matter to rest until more detinite information is 

 obtained in regard to some of the preparations, but as it is questionable 

 when time will be found to continue the work, I have, at the suggestion 

 of a member of your Association, decided to present the accumulated 

 facts at this meeting. In doing this I hope it will be understood that 

 what is said is more in the line of suggestion than anything else. If 

 the statements are received in this light and are found of sufficient 

 interest to be worthy of adoption by yoa in further experimental work, 

 the remarks made shall have served the purpose for which they are 

 intended. The subject may properly be treated under eight heads, as 

 follows: 



(1) Bordeaux mixture. 



(2) Linie-keroseue emulsion. 



(3) Bordeaux-mixture-keroseue emulsion. 



(4) Bordeaux-mixture-kerosene emulsion and Paris green. 



(5) Eesin wash. 



(6) Kesin-wash-keroseue emulsion. 



(7) Resin soap for Bordeaux mixture and for resin wash. 



(8) Sulphur compounds. 



It must be admitted that some of the names for the preparations are 

 cumbersome, but they are indicative, and for the present purpose this 

 is perhaps all that is necessary. 



(IJ Bordeaux mixture. — Although not a new thing by any means, 

 it seems best, in view of what follows, to describe briefly some recent 

 improvements in making this preparation, which is rapidly supersed- 

 ing all other fungicides and is also coming into use as an insecticide
