New YorkK 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 and of 
being of use to the maker.
