are so strong that they would also kill all the bees. The 

 treatment, therefore, which will cure a hive in the early stages 

 of the disease is absolutely useless in the advanced stages, and 

 this fact the bee-keeper must never forget. 



Do not mistake chilled hrood for foul brood. If brood 

 becomes too cold it dies, hut thereafter, in time, it turns black, 

 never broivn, as in foul brood. Later on it dries up and be 

 comes hard; it never forms a sticky, putrescent mass of coffee- 

 coloured, "ropy," or pappy matter, such as is to be found in 

 cases of foul brood. 



The Treatment of Foul Brood in its First Stages. 

 We will now deal with the remedies which will cure the 

 disease in its first stages, of which the best known are the

 the food. The solution for spraying the combs is made as

 acid, by itself, is practically insoluble in water) : all the 

 honey in the hive must be uncapped, and the solution projected 

 on to the combs in a fine spray from a spray diffuser (fig, 41).
