Insecticide

Patent for an insecticide specifically for insects that burrow into the shucks of corn. "The general object of my invention is to provide a compound capable, when affected by moisture incidental to the sweating of the corn in the crib, of generating a poisonous gas which will permeate the shucks and reach and destroy the insect within the shucks, where it cannot be destroyed by simply sprinkling the corn with a poisonous powder or solution" (lines 17-25)
