SPRAYING AND SPRAYING MATERIALS. 1 55 



Treatment with Corrosive Sublimate. Dissolve one ounce cor- 

 rosive sublimate in hot water, in wooden or earthen vessel. When 

 dissolved add water to make up to 7 x / 2 gallons. Put potatoes into 

 sack and submerge in the solution in the barrel. Let soak for i l / 2 

 hours. As this is a deadly poison, great care must be taken that 

 none is taken internally. This strength is not at all harmful to the 

 hands. 



Treatment with Formaline. Formaline is not as deadly a poison, 

 hence is safer to use than corrosive sublimate. Pour the 4 ounces 

 of formaline into j}/ 2 gallons of water; follow directions as above 

 as to time and method of treating potatoes.
