100 Residual Limestone Valley and Uiyland. 



Davidson loam. — A brown to reddish-brown silty loam, under- 

 lain by a brown or reddish-brown silty clay subsoil. Both soil and 

 subsoil usually contain from 5 to 20 per cent of limestone frag- 

 ments and smaller particles of siliceous rock, the former about 1^ 

 inches in diameter. The soil is usually considerably lighter than 

 the Hagerstown loam, and the subsoil is rather more friable and 

 porous. The surface is gently rolling, and naturally well-drained 

 by many small streams, flowing in channels not deeply eroded. 

 The subsoil is fairly retentive of moisture. The type is derived 

 from blue fossiliferous limestone, in which is interbedded a sili- 

 ceous rock, having in some instances the character of sandstone. 

 Not quite so productive a soil as the Hagerstown loam, but ranks 

 high in the production of corn, sweet and Irish potatoes, melons, 

 and small and orchard fruits. It is also a good soil for hay and 

 forage crops.

Conestoga loam. — Brown loam, 12 inches deep, underlain by 

 liglit clay loam to depth of 30 inches, grading into decomposed 

 schist. Rolling valley land. Derived from decomposition of lime- 

 stone schist; has a greasy or soapy feel when rubbed between 

 the fingers. Recognized as one of the best soils for general agri- 

 cultural purposes.

Lickdale clay loam.— Is a silty loam, (> to 10 inches in depth, 

 underlain by a mottled yellow clay. It occurs in small extent at 

 the foot of the Blue Ridge ^Mountains, and is derived from the 

 wash of the mountains and the adjacent shale formations. vSome- 

 times fragments of gray sandstones are present to the extent of 

 from 5 to 20 per cent. It is low lying, flat land, and poorly drained. 

 Naturally it is very refractory, and is suited only to grass and
