— DESCRIPTION OP PLATS ~ 



The land selected for the experiment had been in corn 

 two or three years previously. It was gently rolling, ^ap- 

 peared to be fairly imiform. Slight variations, where oc- 

 curring appeared to be gradual changes. The highest point 

 was on the northeast part, from which it fell gently away 

 to the southwest. There was a slight depressinn in the 

 southeast portion. The northwest edge bordered grass land 

 which fell away more abruptly. The extreme difference in el- 

 evation of the, experimental ground was perhaps fifteen feet. 



The plats extended from north to south in two series . 

 The north series included plats 1 feo IS, and the south series 

 plats 14 to 26. The plats were 18' by 75'. 45* in the middle 

 was occupied by corn, 15' din each end bare or occupied by 

 millet or soy beans. A strip of 15' was left between the series 

 extending the whole length of the experimental ground from 

 east to west. The corn was planted in hills three feet apart, 

 five kernals to the hill to the better secure a uniform stand 

 of three stalks. Thus each plat contained six rows of 16 hills 

 each. The spaces were left at both ends rather than at one end 

 only. to the better secure com.posite samples which would be com- 

 parable to the soil in the corn. 



Every third plat was reserved as a check.
