and Lee counties, while Anson, Riclimond, Union, Orange, and other 

 counties have representative bodies. In color and other physical char- 

 acteristics these soils are quite similar to the Durham types, but the 

 subsoils are slightly more plastic and somewhat heavier, being of a 

 smoother texture, and possessing a slightly greasy feel. The deep 

 subsoil or substratum of the Granville differs from that of the Durham 

 in having a variegated color, which is frequently formed of Indian red, 

 greenish-gray, purplish drab, and white. The Granville Series is de- 

 rived from the Triassic sandstones and shales. It is possible that the 

 lighter color as compared with the Penn soils, which are also derived 

 from Triassic sandstone, is due to leaching processes. The topography 

 varies from gently rolling to slightly hilly and near the stream courses 

 broken and hilly, and the drainage is splendid. 



The Granville series embraces the following soil types: the coarse 

 sandy loam, fine sandy loam, and gravelly loam. 



GRANVILLE COAKSE SANDY LOAM. 



The surface soil of this type consists of a gray to almost white, 

 coarse, sandy, loam or loamy sand, which at about 4 or 6 inches grades 

 into a yellowish, coarse, sandy loam. The subsoil, beginning anywhere 

 between 10 and 20 inches, is a yellow clay, rather smooth and somewhat 

 plastic. On the lower portion of the 3-foot section an Indian red, gray- 

 ish, or purplish clay is frequently encountered. A number of "gall 

 spots" are included in the type representing areas where the surface soil 

 has been washed away, leaving a grayish or Indian red clay. This 

 type of soil closely resembles the Durham coarse sandy loam in sur- 

 face appearances. 



The Granville coarse sandy loam has already been mapped in Gran- 

 ville, Eichmond, and "Wake counties, and areas will probably be encoun- 

 tered in the adjoining counties, particularly in Durham County. This 

 soil is especially adapted to the production of bright yellow tobacco. It 

 produces a beautiful leaf which sells at high prices, being in demand 

 for cigarettes and smoking tobacco. In addition to tobacco, com, oats, 

 rye, crimson clover, sweet potatoes, peanuts, and garden vegetables are 

 successfully grown. This type is well developed in the vicinity of 

 Creedmoor and to the north of Apex. 



The Granville coarse sandy loam, "shallow phase," consists of a gray 

 to purplish gray, coarse to medium sandy loam. The subsoil is a coarse 

 sandy clay of variegated color (purplish, bluish, gray, Indian red or 

 white) to a depth of about 24 to 36 inches, grading into sticky, plastic, 

 micaceous clay of greenish-gray, or Indian red color. This is an ero- 

 sional phase, representing areas where the original sandy surface mate- 

 rial has been largely removed. This phase has a small development. 

 Tobacco gives a darker and heavier leaf, while the yields of corn and 

 grains are equal to those of the typical type.
