Remedies : Keep Italian Bees in preference to Blacks, and use 

 modern hives and modern methods. Bee Moth larvce can he easily 

 killed by confining infested comb in an air-tight receptacle and placing 

 bisulphide of carbon therein. Tzvo treatments at intervals of three 

 zveeks might be necessary. 



Carbon bisulphide is very volatile, and the gas, when mixed with 

 air, highly explosive, therefore, bring no light near it. Our old comb, 

 or comb-honey intended for feeding is kept in air-tight galvanized iron 

 boxes, about two feet square at ends, and four feet long. The Bee 

 Moth, in its various stages, is easily controlled under these condi- 

 tions with bisulphide of carbon, as above suggested. 



AMERICAN FOUL BROOD.

This contagious bacterial disease, known as Bacillus larvce. White, 

 is undoubtedly the bee-keeper's worst enemy in the western states. 

 This is in part because it is so little understood by the majority of 

 bee-keepers, who do not realize how insidious a disease carried by 

 spores or "germs" may be, and how easily it spreads from hive to 



hive. 



Although called American Foul Brood, it is prevalent in Europe. 

 It need not be confounded with the European Foul Brood or "Black 

 Brood," which is not nearly so common as the first named disease, 

 from which it can easily be distinguished as noted below. It calls for 

 practically the same treatment as the first named.
