addition of trouble or expense. The same holds true for a combination 
of Bordeaux mixture with an arsenical for the apple scab and the cod- 
ling moth, and many other illustrations will at once suggest themselves. 
Mr. Smith asked if the effect of combining ammoniacal 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 paper by 
Mr. Galloway: 
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 definite 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 you 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) Lime-keroseue emulsion. 
(3) Bordeaux-mixture-kerosene emulsion. 
(4) Bordeaux-mixture-kerosene emulsion and Paris green. 
(5) Resin wash. 
(6) Kesin- wash-kerosene 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. 
(1 ) 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
