apart." In the second, the seed was cut into two-eye pieces and 

 planted in twenty-two hills, each 18 inches apart. In the third, the 

 potatoes were planted whole in eleven hills, or only cut sufRciently to 

 fill out the section, with the hills 36 inches apart. All of the varieties 

 sj^routed evenh% but owing to the heat and moisture of the season all 

 growth of vines ceased before August 1. The results for each variety 

 are given in a table which shows the yield of both the merchantable 

 and small potatoes for each of the three sj^stems of planting, the 

 average total yield, and the percentage of the total number of tubers 

 affected by the potato rot. This season two-eye pieces planted 18 

 inches apart gave the best results. The average yield of the entire 

 list of varieties was 54.19 bushels per acre.
