piles, for the potatoes in them are almost certain to 

 undergo a heat which will destroy their keeping and 

 germinating power. This is a serious matter in stor-

 with a false floor, and separated one from the other 

 by a two-inch air space. Direct sunlight should be 

 kept from the storage. Subdued light or electricity 

 will not cause the tubers to turn green and unfit for 

 cooking. Finally, only sound tubers should be stored. 

 The storage house should be carefully cleaned out 

 before the crop is brought in from the field and the 

 interior walls and woodwork thoroughly disinfected 

 by burning flowers of sulphur.

 in double-headed barrels, as is done for apples. No 

 matter in what receptacles potatoes are shipped, it 

 is imperative to avoid rough handling and to pack 

 securely. This will prevent shaking and bruising of 

 the tubers while in transit. The cars should be 

 cleaned and protected from leakage. During ex- 

 treme cold weather, the cars should be generously 

 supplied with a layer of straw at the bottom and at 

 the sides.

 are no longer justified in allowing their potato crops 

 to be carried off by disease. 



Seed Selection. Most of the potato diseases are
