48 HATCH EXPERIMENT STATION. [Jan. 



There were besides 19 other varieties giving the same or 

 higher yield at the earlier digging. These varieties are : 

 Carmen No. 1, 295.5; Country Gentleman, 251.5; Dreer's 

 Standard, 272.8; Early Kansas, 298.5; Early Roberts, 

 300; Early Vermont, 266.7; Irish Cobbler, 260.6; King 

 of the Earliest, 265.2; Lakeside Champion, 245.5; Lee's 

 Favorite, 278.8 ; Maule's Thoroughbred, 260.6 ; Prince Bis- 

 marck, 269.7 ; Prize Taker, 244 ; Secretary Wilson, 266.7 ; 

 Signal, 251.5; Tonhocks, 248.5; Vick's Perfection, 284.9; 

 Victory, P. and W., 278.8 ; Wisconsin Beauty, 251.5. 



It will be noticed that the old Beauty of Hebron and Early 

 Rose are found in both lists, thus ranking still among the most 

 productive sorts, whether for early or late harvest. 



There is surely no lack of good varieties of potatoes to 

 choose from, and between many there can be but little dif- 

 ference in value. A single test does not warrant general 

 conclusions. Good northern-grown seed is in my opinion 

 of more importance than name. It is, however, evident that 

 there are a few varieties on our list which seem unworthy of 

 further trial. Among varieties which have made good yields 

 three or more years may be mentioned : Beauty of Hebron, 

 Button's Seedling, Early Rose, Enormous, Fillbasket, Pro- 

 lific Rose, Restaurant, State of Maine, Thorburn, Vanguard 

 and White Elephant. 



Experiments in manuring Grass Lands. 



The system of using wood ashes, ground bone and muriate 

 of potash, and manure in rotation upon grass land has been 

 continued. We have three large plots (between two and 

 one-half and four acres each) under this treatment. Under 

 this system each plot receives wood ashes at the rate of 1 

 ton per acre one year ; the next year, ground bone 600 

 pounds and muriate of potash 200 pounds per acre ; and 

 the third year, manure at the rate of 8 tons. The system 

 is so planned that each year we have one plot under each 

 manuring. The manure is always applied in the fall, the 

 other materials early in the spring, — this year April 21 

 • and 22. 



Plot 1, which this year received barn-yard manure, ap- 

 plied Nov. 16, 1898, gave a yield at the rate of 2.095 tons
