Field B. 



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

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

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

 The systematic treatment of the area was inaugurated in 

 1884, when the present sul)division 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 l)one and 200 pounds of nuiriate of 

 potash per acre. The space of five feet left between the 

 different succeeding plats has been kept clean from any 

 growth by a constant use of the cultivator, and received at 

 no time any kind of manure. 



The details of the work carried on upon Field B have 

 been thus far reported from year to year in our annual 

 reports. The chemical analyses of the crops raised upon 

 this field, on account of the amount of work involved, have 

 been quite frequently published in later bulletins or in 

 annual reports of the succeeding year. 



A material change in the above-stated management of the 

 field was made in 1S89, with reference to the previously 

 unmanured })lats, 12, 14, K!, IS and 20; they were sul)se- 

 quently annually manured in exactly the same manner as the 

 remaining plats, receiving per acre 600 pounds of fine- 

 ground bone and 200 pound^s of muriate of potash. The 

 character of the crops raised upon the various })lats from 

 1888 to 1892 may l)e seen from the following tabular state-
