Both experiments were conducted on dark gray sandy 

 or loamy branch bottom soil, rather retentive of mois- 

 ture. The earlier experiment was preceded by corn, the 

 later one bv cotton. 



The field had been cleared about 75 years and the origi- 

 nal growth is reported as sweet gum, red and white oak, 

 hickory, ash, poplar, cucumber tree, and a few short-leaf 

 pines, and chestnuts. 



The latter part of the season of 1899 was dry and un- 

 favorable and in 1900 there was almost continuous wet 

 weather during the season of cultivation. The soil was 

 worked June 25, 1900, when too wet, by which the ex- 

 perimenter reports that the crop was greatly damaged.
