Sets were cut from medium to large potatoes which had been selected for the 

 arrangement of eyes, to three size?, 1, 2 and 3 eyes; 66 sets were used in each cas£, 

 planted in drills 30 inches apart and one foot apart in the drills. 



The above tables indicate that the sets cut to 3 eyes gave slightly better results. 

 This was also noticeable in the growth of tops. The plants were more vigorous. 



Potatoes. — Selection Work. 



The six varieties of potatoes used in connection with the hill selection work last 

 year, were again selected this spring and 188 hills planted. At digging time 100 hills 

 were selected from these 188 hills, and compared with 100 hills as they came from the 

 rows in the multiplier plots. In every case there was a marked difference in favour of 

 the selected hills. 



Another variety was added to this selection work known as " Pride of the North ". 

 It is a red potato but is excellent for table purposes.

The experiment dealing with the diiferent distances of planting gave very interest- 

 ing results as can be seen by examining the following tables. However, these data are 

 obtained from but one year's work but were done in duplicate. 



Green Mountain potatoes were used throughout. The seed was uniform and clean 

 of scab, nevertheless all seed was previously treated with mercuric chloride, and when 

 harvested the tubers were found to be perfectly clean.
