Distance of Planting. 



KINDS OF CULTIVATION. 



From the results obtained from the plots, it seems evident that three cultivations 

 are preferable. To be more explicit, cultivate twice and let the hilling up act as the 

 third cultivation. 



In growing an acre of potatoes to ascertain the cost of production two varieties 

 were used, Irish Cobbler for the early variety and Green Mountain for thedate or main 

 crop variety. One-half an acre of each was grown on a uniform piece of land. 



Preparation of the soil. — Early in the fall of 191-i the land was ploughed and 

 worked up so as to destroy weeds and prepare the soil to absorb and retain large 

 amounts of moisture. During the winter a coat of green manure was applied, at the 

 rate of 10 tons per acre. This manure was ploughed under as soon as the condition 

 of the soil would permit its being worked without injuring its texture. 



The double cutaway disc harrow was used twice to break up the soil, followed with 

 the smoothing harrow. 



Before planting, the roller was used to break the clods and make an even surface 

 besides compacting the soil. The drills were made with an ordinary Lister plough 30 

 inches apart.
