EXPEEIMENTS WITH POTATOES. 



One hundred and eleven named varieties have been tested during 1891, and 153 

 seedlings. The boil and treatment was the same as that described under mangels. 

 They were planted in rows 2^ feet apart. The dates of planting and harvesting are 

 given in the tables, the hize of the plots, the yield per acre in bushels and pounds, 

 the proportion of marketable and unmarketable potatoes — all those of 2 inches in 

 diameter and upwards being i-egarded as marketable. The total yield is given, also 

 the weight of the diseased tubers. The results obtained from the named varieties 

 only are submitted in the tables. The yield per acre in most cases has been calcu- 

 lated from the product of two rows, each 86 feet in length : —
