number of young bees; thus increasing the population so 
rapidly that the older workers may not be able to drive in 
enough fresh air; or they may be so busy gathering honey 
that they do not leave a sufficient number to do it 
thoroughly. It is quite probable that overheating injures 
the delicate gauze-like wings just as they are unfolding as 
the bee nears maturity, and hence the young thus affected 
will vainly attempt to fly. 
The Cure for May Disease 
is of course very evident, but with proper ventilation 
provided, the effect though certain as regards further 
young that may leave the cells, is not, of much avail so 
far as the bees already affected may be concerned. 
It is a very strange fact that the sudden advent of great 
heat will frequently show the first symptoms of the Isle of 
Wight disease in a stock hitherto apparently quite healthy, 
while others known to be slightly affected are immediately 
found to be in a worse state. Thus 
The question of thorough ventilation* 
is one that must be very seriously considered by every 
bee-keeper. In the above-mentioned rapid development 
of Isle of Wight disease usually oniy the adult bees are 
troubled, as distinguished from May disease, affecting the 
very young. 
Paralysis from Local Poisoning 
will sometimes be found to occur with bees that have 
* This must not be confused with excessive ventilation in cold 
weather. A wide entrance in cool weather, exposed to wind is 
detrimental; but a restricted entrance and heavy quilting will 
always be fatal. A small entrance, with the quilts removed, will 
be beneficial. Swarms slightly affected may always be cured if 
hived with no quilting until ready for supering. See also ‘‘ Swarm- 
ing without Increase.”
