The Potato Crops' 



in. Fruit or berry of potato (X %)- 



GroM'ers commonly prefer to dispose of the potato crop 

 before winter, as it is heavy and bulky to store and shrink- 

 age is likely to be heavy. If the crop has been grown free 



from disease and well 

 matured, however, it keeps 

 well, in ordinary cool un- 

 heated cellars, in pits or 

 in houses constriicted for 

 the purpose. Houses 

 should be certainly frost- 

 proof and capable of main- 

 taining a temperature of 

 approximately 40 degrees. 

 Some of the forms of storage pits are shown in Chapter 

 XIX. The illustrations show types of storage structures 

 as described by Wil- 

 liam Stuart in Farm- 

 ers' Bulletin 847, U. S. 

 Department of Agri- 

 culture. Pig. 108 is a

 ion. Pig. 109 is Maine type of potato storage-^ouse, with
