100 bushels of choice potatoes per acre were raised on a twenty acre field 

 and were sold for an average of one dollar per bushel, the entire work of

 which are usually easily controlled by close attention and the use of proper 

 remedies.

PREPARING THE SOIL. 



To secure a good croxj of potatoes much care and attention must be 

 given to the preparation of the seed and root bed, A glance at cut Xo. 6 

 shows the ideal condition. This soil was plowed eight inches deep after 

 having been thoroughly disced to a depth of fully three and a half inches; 

 the discing having been done early our soil was moist and was in the best 

 possible condition to plow; as the furrow rolled over the fine, dry top soil 

 went under, the moist soil coming to the surface in an ideal condition, and 

 while moist the particles seemed to readily separate one from the other 

 and adjust themselves without material resistence to the desired compact- 

 ness, as the packer wheels rolled over the plowed ground, which was done 

 quite close to the plow. While we have said much upon the importance of 

 a proper condition of the soil when all work is done, we must almost repeat
