Great care should be used to prevent other bees getting any of 
the honey from the infected combs, and if there is any possibility 
of honey dropping from them to the ground during treatment news- 
papers should be spread to catch any possible drops and the paper 
burned. 
After treatment the hive body, bottom and top should be scorched 
or in some manner subjected to over 212°F. to free them from in- 
fection which may be on them. 
No disinfectants known are effective in killing the germ caus- 
ing American foulbrood. 
The frames may be made safe for further use by boiling for 
half an hour, by dipping in boiling lye water, one can of lye to 
a washboiler of water, or by subjecting to rather high heat by baking. 
One New Jersey beekeeper successfully got the bees out of the 
infected hive into the clean one by placing the infected colony over 
the clean hive with nothing between and smoked and brushed the 
bees down as the combs were removed one by one. 
Any honey which may be in the combs may be extracted and 
put to family use, or it may be diluted with an equal amount of 
water, boiled for half an hour in a closed vessel and fed to bees. 
This should never be fed when it will be used for winter stores, 
as it will surely cause dysentery and death to the bees. 
European Foulbrood 
Description—This is a disease of the brood of bees caused by 
bacillus pluton White.* This organism causes death of the larvae 
in the majority of cases before the time for sealing has arrived. The 
color of the affected larvae differs much. It may be discolored 
only by having a yellow spot near the head, or it may be a light 
brown or a dark brown. The odor when present, which is not 
always, is distinctive but not easily described. It resembles in a 
measure the odor of ear wax (cerumen). ‘The position of dead 
larvae also varies and in truth it may be said that there is practi- 
cally no possible position in the cell which the dead larvae do 
not assume. The per cent of larvae affected also varies and may 
involve a very few cells up to ninety per cent of the larvae. Its 
progress in the colony is often rapid but may be slow. Thus it will 
be seen that the symptoms are exceedingly variable. As the writer 
has had opportunity to study the manifestations of this disease in 
New Jersey the most dependable symptom is the position of the larval 
remains (seales) in the cells and the shape of the scales them- 
selves. The scales are exceedingly irregular in form, and their
