about feebly, but very few dead ones were found. During that day and 
the following day the bees were watched carefully and their activities 
seemed to be perfectly normal. At the end of the second day the bees 
were taken back to the apiary from whence they came. About 125 
dead bees were found inside the cabinet and 65 live bees that had not 
found their way back to the hive, were also collected. These were 
placed in separate vials to be submitted to a chemist for analysis to 
determine whether they would show any traces of arsenic. 
On the afternoon of April 21 with the owner of the bees, I made an 
examination of the colony that had been returned to the apiary. We 
found them working in an apparently normal way and we found that 
they had been storing honey during the two days that they were in the 
cabinet. All of the larvae seemed to be in normal condition; a number 
of cells were open and it is to be presumed that the larvae were being 
fed during the time of the experiment, otherwise they would have died. 
The queen had been laying eggs, and there was nothing about the colony 
to suggest any unusual conditions. I may add here that this colony was 
observed from time to time during the following year and no unusual 
conditions were noted. 
On April 22, in order to check the first experiment the cabinet was 
placed over another tree near the one that had been sprayed for the 
first experiment. This tree was about the same size and shape and in 
about the same condition as regards blossoming as the tree used in the 
experiment. We then selected another colony of bees that corre¬ 
sponded as nearly as possible in every way to the colony that had been 
placed under the cabinet in the first experiment. This colony was 
placed under the cabinet with the tree that had not been sprayed and 
their behavior carefully noted. The first ones that came out flew 
about uneasily for awhile, many of them flying to the top of the cover 
where some of them stayed. Many of them soon began to feed on the 
blossoms and in a short time they were feeding in a perfectly normal 
way. In the evening it was noted that a number were still clinging to 
the top of the cover, a few were found dead on the ground, and a few 
were crawling about in the grass. There was some brown spotting on 
the top of the hive and on a strip of cardboard placed on the ground in 
front of the hive; similar spots to these were seen during the progress of 
the first experiment, and there seems to be nothing abnormal about 
these spots. The number we found is doubtless due to the fact that the 
bees could not fly far away and any droppings from them would, there¬ 
fore, be more numerous in the inclosed space and so more conspicuous.
