the collections from clover on fields adjacent to the dusted potatoes 
where the dust floats and settles on the clover. It has also been 
suggested that bees get the poison from leaves of plants when gather- 
ing moisture from them. In support of this theory is the fact that 
in some samples of affected bees subjected to chemical analysis 
arsenic was found in sufficient quantity, it is believed, to kill the bees. 
On the other hand no poison was found in other samples in no 
way, so far as could be seen, differing from those which showed 
arsenic. 
Remedial Measures—The only suggestion which can be given to 
a beekeeper whose bees are troubled with this disorder is to move 
them out of the affected zone. 
It has been suggested that this disorder, the Isle of Wight disease 
and May disease are the same under different names. This, also, is 
mere conjecture. 
Dysentery 
This is a trouble which is sometimes experienced by adult bees 
and is due to their being confined to the hive for a long time by 
low temperature when the stores contain much material which is 
indigestible by bees. Under this condition there is a great ac- 
cumulation in the intestines. The bees normally void this ac- 
cumulation while on the wing. However, when it becomes great 
they may be forced to void it in the hive. When this occurs the 
trames, combs and bees are befouled, and unless the bees shortly 
get relief in flight they perish. 
Preventive Measures—No remedial measures are open to the 
beekeeper, but he must depend upon the weather for the only help 
that can be given. He can nevertheless take precautions against 
this condition. These are (1) if the stores are of doubtful quality 
he can feed, in the fall after the bees have ceased gathering from 
natural sources, five or more pounds of sugar made into a syrup. 
Mix one part of hot water and two parts by weight or measure 
of sugar; and (2) he can provide an abundance of winter packing 
and thus slow down consumption and consequently the accumulation 
of feces. 
ENEMIES 
Birds 
Some birds, prominent in the list of which is the king bird, 
have been accused of being enemies of bees in that they catch them 
while on the wing. The few drones or workers which might be so 
caught would hardly make any appreciable difference to the colony.
