CAUTION ! 
should be the bee-keeper’s watchword, while extreme 
vigilance will bring its own reward. Those who have 
never seen foul brood should be most careful to note that 
frequently in summer its appearance is to be discovered 
by irregular or “patchy” slabs of brood, among which 
there are no black or rotting grubs whatever; for while the 
bees are actually storing, every sickly larva is at once 
removed ; so that when patches of brood known to have 
been quite compact are presently of irregular ages and 
appearance, it is time to be suspicious. Even at this stage 
the experienced eye may detect occasional sickly grubs, 
and some may not even be discolored. If a single larva 
lies in an irregular position in its cell, then the owner’s 
suspicions must be aroused, and the combs kept under close 
observation. 
There is only one position that the unsealed larva should 
occupy, and that may be described as a crescent form, and’ 
always so presented to the observer. The exception is 
sometimes to be found in the case of: drone brood in 
worker cells when the grub is too large for its cradle. 
Several Forms of Brood Disease. 
Cheshire found bees were troubled with several brood 
diseases, though he did not name them all. Later investi- 
gators with improved instruments have been able to verify 
his statements, and have named other disease germs which 
they consider more fatal than Baczllus alvet. 
Our American friends are now describing B. alvez as 
European foul brood, or black brood; and the more 
virulent form as American foul brood. The reader may 
rest assured that the treatment given herein will enable 
him to cure any form of the disease, if he will only act 
without delay.
