2. Field Experiments with Several Prominent Vari- 

 eties OF Grasses and of Potatoes. 



Field B. 



This field occupies an area of one and seven-tenths acres, 

 and runs from north to south, nearly on a level. The soil 

 consists of a somewhat sandy loam of several feet in depth. 

 The systematic treatment of the area was inaugurated in 

 1884, when the present subdivision into eleven plats was 

 first introduced. The plats are 175 feet long and 33 feet 

 wide (5,775 square feet, or two-fifteenths of an acre), of a 

 uniform shape, running from east to west, with a space of 

 five feet between adjoining plats. The numbering begins at 

 the north end with 11, and closes at the south end with 21. 

 From 1884 to 1889 every alternate plat received annually 

 the same kind and the same amount of fertilizer, — 600 

 pounds of fine-ground bone and 200 pounds of muriate of 

 potash per acre. 



From 1889 to the close of the season of 1892 all plats 

 were treated alike, as far as the system of cultivation and 

 of manuring is concerned. The previously stated unma- 

 nured plats (12, 14, 16, 18 and 20) received from 1890, like 

 the remaining plats (11, 13, 15, 17, 19 and 21), as manure 

 annually at the rate of 600 pounds of fine-ground bone and 

 200 pounds of muriate of potash, applied broadcast either as 

 a top dressing or thoroughly ploughed under, as circum- 

 stances admitted. 



For details regarding the work carried on upon Field B 

 previous to 1892, see tenth annual report. 



The character of the crops raised during 1892 may be
