New York Agricultural Experiment Station. 51 



Specific directions for freeing a factory once infested cannot 

 be given from the amount of data at hand, but plenty of hot 

 water, followed by plenty of live steam on the vats, cans and 

 working utensils, seems to be called for by the above experi- 

 ences. We will be pleased to correspond with and, as far as 

 practicable, visit every factoryman in the State having this 

 trouble, in the hope both of learning something ourselves aad of 

 being of use to the maker.
