However, one application will accomplish little with any 

 of them. It must be dusted over the floor, behind the 

 boxes, on the shelves, and in every other place frequented 

 by the roaches several nights in succession and subse- 

 quently should the roaches appear again. 



A powder, known as Insectoline, manufactured by the 

 Insectoline Company, Cincinnati, Ohio, has given good 

 results in fighting these insects. The author has used it 

 in kitchens and pantries with satisfactory effect. A large 

 dwelling-house at Stonewall, Mississippi, that had be-

 results with this powder it must be applied thoroughly 

 and persistently.

 freely in the kitchen, with marked success. This was 

 sprinkled in cracks about the sink, along the top of base- 

 boards, near the sink, and elsewhere wherever there were 

 cracks which afforded the insects a hiding place. By a

 recommended report the same success, and in conversation 

 with other economic entomologists we hear unqualified 

 praise for the*' borax method.' i 



Whatever powder or other substance is used it must 

 be applied in large quantities over an extended period of 

 time. Moreover, the material must be applied fre-
