THE POTATO. 245 



crop of the potatoes is sometimes produced when the 

 tops have made but small gi'owth. 



The crop should be harvested before frost. If frost 

 unexpectedly comes the vines should at once be cut 

 close to the ground. 



The sweet potato requires more careful handling 

 than the common potato. It should be well dried be- 

 fore being stored, and must be kept warmer than is 

 desirable for the common potato. 



Under favorable conditions the yield is enormously 

 large; the average vield is greater than that of the 

 common potato.
