comparing shallow planting with high ridge cultivation, some- 

 what deeper planting with a lower, broader ridge, and deep 

 planting with as level cultivation as practicable, was begun. 

 This was continued through four years with two varieties 

 of potatoes. The results of the exepriment are here reported. 

 The deep planted lots were planted at a depth of 5 inches, the 

 medium at 3^2 inches and the shallow at 2 inches. 



Full data as to the planting, cultivation, spraying and har- 

 vesting of the crop were kept each season. But in an experi- 

 ment of this type it does not seem wise to use space in report- 

 ing details that, while they are important in showing that the 

 crop was carefully grown, have little agricultural significance 

 beyond that fact. 



The yields for the four years are given in the table which 

 follows :
