212 DISEASES AND ENEMIES OF BEES 
to feed anything. It is regarded as unsafe to feed the honey from 
hives infected with this disease, as high temperature for con- 
siderable length of time is necessary to insure death of all spores. 
In the hands of a novice it frequently happens that the boiling is 
not sufficiently thorough and healthy bees are thus infected. 
Treatment of American Foul Brood.—This disease is rather 
slow in its progress, but very sure, and once a colony becomes 
infected its final death is certain, unless the bees are removed 
toa clean hive and the infected brood destroyed. In the hands of 
the average bee-keeper the shaking treatment, commonly called 
the McEvoy treatment, is best. McEvoy, who was for a time 
inspector for Ontario, was very successful in treating foul brood 
and he it was who probably first brought suecessful methods of 
treatment prominently before the public. However, the essen- 
tials of this method were described in Europe many vears before 
the birth of McEvoy, and Quinby had also long made use of shak- 
ing for the cure of foul brood in this country. 
The first essential is to remove the bees entirely from the 
source of the disease, and they should accordingly be placed in 
a clean hive on the old stand and the old combs, brood, and honey 
all removed. McEvoy allowed them to build new combs for 
four davs, thus insuring that all honey carried with them would 
be used, and then again shook them into another clean hive and 
destroyed the combs that they had built in the meantime. The 
second shaking is not always necessary. By using good judg- 
ment the bee-keeper can usually tell when conditions are such 
that a second shaking will be necessary. 
The instructions given from the office of the Iowa Inspector 
are as follows: 
In the evening after the bees have stopped flying, brush or shake all 
the bees into a clean hive containing foundation starters. Bury or burn 
the old combs at once, not the next day. Take great care that no honey, 
not even the smallest drop, be exposed to the bees, or the disease may be 
carried back or exposed to healthy colonies. 
This is essentially the instruction given for years past by 
yarious State officials charged with enforcement of foul brood
