should recommence from the end of February, as the 
essential curative principles of any germicide stored for 
several months in the food either evaporate or become 
weaker. 
The partial success of a writer in the British Bee Journal 
of April 24th, 1913, who followed the plan of wintering on 
medicated food, is to be explained by the facts set out in 
the preceding paragraph. 
Sources of Danger disposed of. 
An essential feature is that young bees must be produced 
in September in sufficient numbers that the old stores of 
pollen, etc. are largely disposed of; as also the old. bees 
that are another source of danger, 
Adding Driven Bees. 
Where brood is not available, the reduced stocks may be 
made up with driven bees if these can be procured locaily, 
or from not too great a distance. In all cases the bees 
should be fed up rapidly with medicated food. Human 
beings can be treated without medicine, but bees living in 
such vast numbers and in close contact may not be 
managed in just the same way. Nevertheless I have 
always insisted that recuperative measures are of as much 
importance as the best germicide, and should always be 
adopted in combination. 
May Disease 
is a malady sometimes mistaken for the Isle of Wight 
paralysis, but it does not appear to be infectious, and 
usually only the very young bees seem to be affected, 
and should these be picked up they are quite prepared 
to use their stings. 
The cause is to be found in a sudden accession of heat 
just as a badly ventilated hive may be hatching a large
