Field D, 1888. — This field is 328 feet long and 70 feet 

 wide, covering an area of 22,960 square feet. It has been 

 used during previous years for the raising of a variety of 

 garden and field cropa, on a larger or smaller scale. The 

 soil has been usually ploughed late in 

 the fall and early in the succeeding 

 spring. The manure has been applied 

 in every instance early in the spring, 

 after ploughing, and subsequently 

 slightly harrowed under. With the 

 exception of the potato plats used for 

 studying the causes of the scab on 

 potatoes, but one fertilizer, consisting 

 of fine-oTound bones with muriate of 

 potash, six hundred pounds of the 

 former and two hundred pounds of the 

 latter per acre, has lieen used upon 

 this field. The distribution of the 

 crops raised during the year 1888 may 

 be seen from the accompanying sketch. 

 Some analyses of crops raised during 

 that year are for stated reasons pub- 

 lished farther on for the first time, in 

 connection with analyses made of crops 

 raised during the present year. 



1889. — The preparation of the soil, 

 as well as the system of manuring, was 

 in all its details the same as in the 

 preceding years. The crops were 

 planted in rows, and kept clean by the 

 timely use of the cultivator and the 

 hoe. They were arranged in the fol- 

 lowing order, beginning at the west 

 end of the field : — 



Red-cob Ensilage Corn. — The seed
