infested seed. To clean the seed, soak the potatoes for one hour in a 

 solution made of one pint of formalin, which can be bought at any drug 

 store,' mixed with 30 gallons of water. A convenient way is to put the 

 seed potatoes in an old sack and lower them into the solution. At the 

 end of the soaking lift the potatoes out of the solution so that they will 

 drain and then spread them out on a clean place to dry. 



Where the land is badly infested with scab it is well to plant other 

 crops for several years until the soil becomes free from the fungus. The 

 scab fungus does not thrive in acid soil. Because lime lessens acidity 

 it has been thought by some to be responsible for the appearance of scab. 

 Lime applied to land does not cause scab, but it makes a more favorable 

 condition for scab to spread. If your soil is clean and your seed potatoes 

 are always thoroughly treated, you can apply lime without danger from 

 scab. 



Sending specimens to the station. If you have specimens of dis- 

 eased or insect-infested plants about which you wish advice, put speci-
