 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.

 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-
