braced in the Hagerstown series. 



Hagerstown Series . - The Hagerstown series is formed 

 mainly from the solution and subsequent filtration of pure 

 massive limestone of Cambro -Silurian age. These soils, as a 

 rule, occur in valleys bordered by areas of more resistant sand- 

 stones and shales. 



Hagerstown stony loam to an average depth of 8 inches, 

 consists of silty or fine sandy loam usually brown in color, 

 but varying from light gray to yellowish. The subsoil con- 

 sists of a yellow or yellowish red clay loam grading at an 

 average depth of 24 inches into a stiff red clay which ex- 

 tends to unknown depths. On the surface, and in the soil and 

 first few inches of the subsoil occurs a high percentage of 

 angular chert fragments. This type of soil is residual and 

 is derived from the solution of impure limestone containing 

 cherty layers, the insoluble material being concentrated on 

 the surface. Hagerstown stony loam occupies high ridges in 

 the limestone valleys. 



The distribution of this soil type in the areas where 



soil surveys have been made is shown from the date given below.
