2. South Division, Garden Crojis. 



This part of Field C, 328 feet long and 88 feet wide 

 (28,864 square feet), was sul)divided as above stated during 

 the spring of 1891 into five plats of a uniform size and shape 

 (88 feet by Q'2 feet, one-eighth of an acre), running from 

 north to south across the main field. These were separated 

 from each other by an unmanured space of from four to five 

 feet in width. The soil was several feet deep, and consisted 

 of a rather light loam in a good state of cultivation as far as 

 its mechanical condition is concerned. No other manurial 

 matter but fine-ground bone and muriate of potash, 600 

 pounds of the former and 200 pounds of the latter per acre, 

 was used before 1891. The field slopes very gently from 

 west to east. The plats were numbered 1, 2, 3, 4, 5, 

 beginning on the east end of the field. Each plat received, 

 spring of 1891, a manurial mixture of its own as fertilizer. 

 The difference of the fertilizers applied consisted essentially 

 in the circumstance that nitrogen and potash were used in 

 several of them in different forms. All plats received 

 practically the same quantity of nitrogen, potash and phos- 

 phoric acid, and every one of them received its phosphoric 

 acid addition in the same form, namely, dissolved bone-black. 

 Some plats received their nitrogen supply in the form of organic 

 animal matter, dried blood ; others received their nitrogen 

 in the form of sodium nitrate. Chili saltpetre ; others in the 

 form of ammonium sulphate. Some plats received their
