 thirty-six gallons of water. The potatoes should 

 then be spread out to dry, when they may be cut 

 and planted in the usual manner. Great care 

 must be taken after potatoes have been treated as

 that have contained scabbed potatoes. 



" (2) Land that has produced scabbed potatoes

 where potatoes are of necessity grown every year,

 should be sprinkled with powdered sulphur.

 soil, etc. Acid manures only should be applied to 

 land that is infected. 



"(5) Peelings from infested potatoes, unless 

 they have been boiled, should not be given to pigs.

TIP BURN, LEAF BURN OR SCALD 



"This disease of the leaves occurs in many parts 

 of the country and is often confused with early 

 blight," says B. T. Galloway in "Farmers' Bulletin 

 No. 91." "The tips and edges of the leaves turn 

 brown and these discolored areas soon become hard 

 and brittle. 



"The burning or scalding may occur at any 

 time and as a rule is the result of unfavorable con-
