The night before the bees are removed from the cellar it is good 
practice to leave the cellar doors and windows wide open. 
DISEASES AND ENEMIES. 
There are two infectious diseases of the brood of bees which cause 
great losses to the beekeeping industry of the United States. These 
are known as American foul brood and European foul brood. Both 
of these diseases destroy colonies by killing the brood, so that there 
are not enough young bees emerging to take the place of the old 
adult bees as these die from natural causes. The adult bees are 
not attacked by either disease. In the hands of careful bee keepers 
both diseases may be controlled, and this requires careful study and 
constant watching. In view of the fact that these diseases are now 
widely distributed throughout the United States, every bee keeper 
should read the available literature on the subject, so that if disease 
enters his apiary he may be able to recognize it before it gets a start. 
The symptoms and the treatment recommended by this depart- 
ment are given in another publication which will be sent free on 
request.' 
It is difficult for a bee keeper to keep his apiary free from disease 
if others about him have diseased colonies which are not properly 
treated. The only way to keep disease under control is for the 
bee keepers in the neighborhood to cooperate in doing everything 
possible to stamp out disease as soon as it appears in a single colony. 
The progressive bee keeper who learns of disease in his neighborhood 
should see to it that the other bee keepers around him are supplied 
with literature describing symptoms and treatment, and should also 
try to induce them to unite in eradicating the malady. Since it is 
so often impossible to get all of the bee keepers in a community 
to treat infected colonies properly and promptly, it is desirable 
that the States pass laws providing for the inspection of apiaries and 
granting to the inspector the power to compel negligent bee keepers 
to treat diseased colonies so that the property of others may not be 
endangered and destroyed. This has been done in a number of 
States, but there are still some where the need is great and in which 
no such provision has been made. When no inspection is provided, 
bee keepers should unite in asking for such protection, so that the 
danger to the industry may be lessened. 
In case there is an inspector for the State or county, he should 
be notified as soon as disease is suspected in the neighborhood. 
Some bee keepers hesitate to report disease through fear that the
