productive. Cotton and the general farm crops are the leading products. 

 The gravelly soil is early and adapted to early truck. 



Elkton series. Light gray to white surface soils, with mottled whitish gray 

 and yellow subsoils, overlying gravel and coarse sands. 



Gadsden series. Gray soils, with subsoils of similar texture occupying 

 gentle slopes and depressions and formed by wash or creep from higher areas. 

 This series occurs in rather local development, particularly in Florida, southern 

 Georgia, and Alabama. They are very productive soils and well adapted to 

 tobacco. No heavy members of the series have been encountered, and it is 

 doubtful if any exist. 



Guin series. Gray soils with brown to yellowish red subsoils, occurring 

 as rolling and hilly lands. Intermediate series between the Norfolk and 

 Orangeburg series. Owing to the rather rough topography, these soils have 

 not been developed as much as either of the other series, although they 

 seem capable of producing better crops than they do now. 



Houston series. Dark gray or black calcareous prairies. One of the most 

 productive series for Upland cotton and well adapted to alfalfa and other 

 forage crops. 



Laredo series. Gray to light brown calcareous soils with gray subsoils. 

 Good cotton, corn, and sugar-cane soils, and especially adapted to the early 

 production of vegetables cabbage and onions in particular. 



Lufkin series. Light-colored soils with heavy mottled gray and yellow 

 subsoils. The soils of this series have only a moderate degree of productivity. 



Montrose series. Gray soils with heavy plastic mottled yellow subsoils. 

 These soils are in part poorly drained, but where cultivated they produce 

 moderate yields of cotton and corn. 



Myatt series. Gray soils with mottled yellow, gray, and whitish subsoils 

 occurring in poorly drained areas around heads of streams and intermediate 

 between uplands and bottom lands. The series seems to be of local extent 

 and but little developed. 



Norfolk series. Light-colored soils with yellow sand or sandy clay sub- 

 soils. This series contains some of the most valuable truck soils of the Atlantic 

 and Gulf Coast states, and certain members of the series are adapted under 

 certain climatic conditions to wheat, grass, tobacco, and fruit. 



Oktibbeha series. Gray soils with brown to yellowish brown heavy sub- 

 soils related to Houston series in origin. The soils of this series are distinctly 

 inferior to the soils of the Houston series and, as they appear to cover large 

 areas in Mississippi and Alabama, present a difficult problem in soil improve- 

 ment. 



Orangeburg series. Light-colored soils with red sandy clay subsoils. 

 This series constitutes some of the best cotton soils of the South, and certain 

 members of the series are particularly adapted to tobacco. 



Portsmouth series. Dark -colored soils with yellow or mottled gray sand 

 or sandy clay subsoils. Where drainage is adequate, this series is adapted 

 to some of the heavier truck crops, to small fruits, and to Indian corn.
