eye, they should give satisfactory results, other conditions being 

 favorable. 



From eleven to twelve bushels of seed to the acre are generally 

 planted in America, though many prominent growers use a 

 larger amount.

8. Planting. — The soil should be in a fine state of division 

 before starting to plant potatoes. Most American potato growers 

 space the rows 30 to 36 inches apart, the closer spacing being 

 favorable to the largest yield. In small gardens which are culti- 

 vated with wheel hoes, the rows, especially of early varieties, need 

 not be more than 26 inches apart. Though potatoes are sometimes 

 planted in hills, the more common practice is to distribute the 

 pieces 12 to 14 inches apart in drills. This gives each plant the 

 best opportunity for development and the plan is the most favor- 

 able for large yields. 



The proper depth of planting is a matter which should have the 

 most careful consideration. In light, friable soils it is universally 

 conceded that the seed should be planted about four inches deep, 

 because this depth of planting is most advantageous from the
