Edgecombe Farm. — This farm is in the coastal plain region and 

 is located in Edgecombe County, about midway between the towns

of the lands of the eastern part of the State. This type of soil 

 responds very readily in remunerative crops to proper fertilization 

 and cultivation, and represents a large and important part of the

 cent of the total area of the State. It is the type of soil designated 

 by the IN^ational Bureau of Soils as Norfolk fine sandy loam.

 the State, lies about one and one-half miles northwest of the corpo-
