Field C. 



This field comprises an area 328 feet long and 183 feet 

 wide ; it is subdivided into two parts, running from east to 

 west ; they are separated by a passage-way three feet wide. 



The system of manuring and of cultivating is the same on 

 both divisions. They are annually manured with a mixture 

 consisting of fine-ground steamed bone, six hundred pounds, 

 and muriate of potash, two hundred pounds, per acre. The 

 field is usually ploughed in the full and early in spring, with 

 the exception of small areas occupied by perennial plants. 

 The fertilizer is applied broadcast early in spring, and sub- 

 sequently slightly harrowed in. 



The crops are in the majority of cases planted in drills, 

 to secure chances for clean cultivation. The land has served, 

 for several years past, for the same purposes ; namely, to 

 ascertain the particular degree of adaptation of reputed fiirm 

 crops to our climate and our soil. In some instances suf- 

 ficient quantities of one or the other were raised to furnish 

 fodder for summer and winter feeding experiments. In the 

 majority of cases, however, the main object of the planting 

 was to secure suitable material for analysis, to determine 

 their relative economical value either for general farm pur- 

 poses or for special industrial purposes. The variety of 

 crops already tested in this connection is quite numerous ; 

 for details regarding previous years, we have to refer to our 

 preceding annual reports. Some analyses of crops raised 

 on fields C and D during the year 1889 are published, for 

 the first time, within a few subsequent pages.
