some other crop ; or, if the soil is somewhat 

 heavy, a good clover sod, plowed under the 

 autumn previous, will make an excellent base 

 on which to grow a heavy crop of potatoes. 



The planting should be done early as soon, 

 in fact, as the soil is in good working order. 

 Our experience has been that, all other things 

 being equal, the earliest planted will yield at 

 least one third more than those which are 

 delayed two or three weeks. 



We are convinced that the majority of peo- 

 ple plant three times as much seed as they 

 should in order to secure the best results. 

 Probably the average amount used in this 

 country for seed will exceed ten bushels per 

 acre, while the average yield will not exceed 

 one hundred bushels, or at most a ten-fold 

 increase. 



Now, we suppose the potato is capable of 

 yielding at the rate of an hundred-fold with 

 common field culture ; and by taking a little 

 extra pains, in favorable situations, different 

 parties have succeeded in doing ten times as 

 well as this, even ; for upward of one thousand 

 pounds have repeatedly been produced from 

 a single pound of seed. 



We have for a number of years practiced
