The BuLLETiisr 



The Durham sandy loam gives fair yields of corn and cotton when 

 fertilized or manured. It is best suited to the growing of sweet potatoes, 

 peanuts, rye, sorghum cane, watermelons, and garden vegetables and 

 fruits. It is admirably adapted to the production of bright tobacco 

 of the cigarette and granulated pipe-smoking type, and is being exten- 

 sively used for this crop in central North Carolina. The soil is very 

 easy to till, warms up early in the spring, and responds freely to the 

 application of fertilizers and manures. It needs more humus, and this 

 can be had by turning under leguminous crops.

DURHAM COARSE SANDY LOAM 



This soil is quite similar to the Durham sandy loam. There are 

 3,200 acres of this land in the county. The largest bodies lie to the east 

 of Concord, to the east of Kannapolis, and in the northwestern part of 

 the county along Rocky River, 



The surface soil is a gray to yellowish-gray loamy coarse sand with 

 considerable fine white quartz gravel, or is composed of a fine sand, 

 silt, and clay with quartz gravel and coarse sand. It is underlain at 

 depths of about 10 to 24 inches by a yellow coarse friable sandy clay 

 Avhich grades into the rotten rock frequently at 24 inches below the sur- 

 face. Flakes of mica are also seen in places. 



It is developed on the nearly level to hilly and broken areas. The 

 more level surface is seen east of Kannapolis, while the rougher areas 

 occur along Rocky River. All of the type is excellently drained, due to
