stable as the old standard ones of soap and milk, and Mr. Galloway 
explained that while this was generally true, many of the mixtures 
were sufficiently stable for practical, immediate use, and that the whole 
matter had been worked out provisionally by him with the idea of 
merely bringing it before the Association so that others having more 
time could take up the matter, make more careful experiments, and 
devise methods and formulas which would bring about the best results.

SPRAYING WITH ARSENITES VS. BEES. 
By F. M. Webster, Wooster, Ohio. 
At the Eochester, N. Y., meeting of this Association, I gave the 
results of some experiments looking toward a solution of the problem, 
Will spraying fruit trees while in bloom affect the bees which after- 
wards visit these trees for the purpose of securing either honey or any 
other substance carried to the hives, and if such be the case, what is 
the effect upon the inmates of such hives ? The results of my first 
attempt at settling this question will be found on record in Insect 
Life, vol. v, pp. 121-123, and it will, therefore, not be necessary for 
me to repeat them here. On account of the meteorological conditions 
under which the experiments were carried on they have never been 
deemed conclusive in point of definite results, even by myself, and I 
have only been waiting a favorable season in order to finish the work. 
This year the time appeared to have arrived in which I might hope 
to solve the problem. 
On May 2 two apple trees in full bloom — and the blossoms were 
abundant — were thoroughly sprayed with a mixture of 1 ounce of Paris 
green to each 12 gallons of water. After the water had evaporated 
the poison could be clearly observed both on bloom and foliage. The 
application was made during the forenoon, the day being warm and 
clear, and during the afternoon quite a number of bees were caught 
while visiting the bloom and marked with carmine ink. The hives 
were located but a few yards distant from the trees, and both being 
situated at a considerable distance from any other trees at that time 
in bloom. None of these marked bees were afterwards found dead 
about the hives. During the night following the application there 
was a rainfall of 0.20 inch. On the following day bees were caught 
and killed by being dropped into a cyanide bottle where the cyanide 
was embedded in plaster of Paris, after the usual custom. As soon as 
the bees were dead they were dissected as follows : The posterior legs 
with pollen attached were severed from the bodies and placed in a 
small glass vial and securely corked. The contents of the abdomens, 
including the honey sacs, were next dissected out and placed in a
