184 AGRICULTURAL EXPERIMENT STATION. [Jan. 



secure as far as practicable a corresponding level position 

 for all of them, and thereby remove the objection of the 

 possible influence of a more or less mclined position and 

 different state of moisture of one or the other on the results. 

 For this purpose the entire width of Field C on its western 

 termination was selected for the future trial. The field thus 

 marked out covered an area 189 feet lono- and 164 feet wide. 

 It was subdivided into six plats of equal size and shape (88 

 by 62 feet), corresponding thus in this particular with those 

 in the preceding year. Three plats of the previous year, 3, 

 4 and 5, remained unchanged ; their numbers were altered 

 into 6, 5 and 4. The new plats were numliered 1, 2, 3, 

 beoinnino; at the west end of the field. The entire area was 

 ploughed April 19, and subsequently staked out as above 

 stated into six plats, with four feet unoccupied space between 

 them. The below' specified fertilizer mixture was applied 

 to each plat broadcast, and the soil subsequently harrowed. 

 On May 10 it was rolled. All the crops were planted in 

 rows two and one-half feet apart ; the different crops were 

 seeded or planted each on the same day in all the plats. 

 The crops were arranged in all ])hits in the same order, 

 which, in the interest of a desiral)le rotation, differed from 

 that in the preceding year (plats 4, 5, 6).
