1894. — As the east side of the field was on a higher level 

 than the west side, it was decided to run the crop across the 

 two plats from east to west, to secure as far as practicable 

 corresponding conditions of the layout of the area occupied 

 by the crops. The northern half of the field thus divided 

 (plats 1 and 2) measured one acre, the southern half one 

 and nine-tenths acres. 



Oats and corn (variety Pride of the North) were selected 

 for our observations. The oats were sown broadcast, at the 

 rate of 4 bushels per acre, upon the northern portion of the 

 field, and the corn was planted in rows 3 feet 3 inches apart, 

 with hills 20 inches from each other, upon the southern por- 

 tion, using 12 quarts of seed corn per acre. The area occu- 

 pied by oats amounted to .35 of an acre of Plat 1 and .65 

 of an acre of Plat 2 ; while the corn occupied .7 of an acre 

 of Plat 1 and 1.2 acres of Plat 2.

To test the reliability of the results obtained, it was de- 

 cided to repeat the experiments above described upon the 

 same field. The fertilizers were used in the same proportion 

 and in the same quantity per acre ; they were applied upon 

 the same portion of the field which had received each kind 

 before. Oats and corn were again selected as crops for the 

 trial. The material change in the experiment consisted in 

 reversing the location of the crops ; the corn was planted at
