PARK WOOD CLAY LOAM. 
The surface soil of the Parkwood clay loam ranges from 4. to 8 
inches in depth, averaging about 6 inches. It consists of a friable 
clay loam, generally quite silty, but in places, especially bordering 
sandy lands, there may be a shallow covering of sandy material, not 
more than an inch or two thick. There is some variation in the 
color of the soil. In the wooded areas and in low spots the color is 
black and the immediate surface is more or less mucky, but in the 
cultivated fields the soil becomes brown to grayish. In the Warm 
Spring hammock the brown color predominates, while in the other 
areas the color is black to grayish. The immediate subsoil consists 
of-a dark-yellow or light yellowish-brown clay or silty clay. This 
becomes lighter, almost white to ocherous yellow, with increase in 
depth. In higher spots in the Warm Spring hammock the upper 
subsoil is for a few inches a dark or rusty-red clay. The thickness 
of the yellow portion of the subsoil varies from an inch or two to 
2 feet, but it usually occupies 6 to 15 inches of the profile section. 
The lower part of the subsoil either contains a noticeable amount of 
yellowish-white to white marl or rotten limestone material, or con¬ 
sists largely of white clayey marl or weathered limestone material. 
Quite often this marly material is near enough the surface to be 
reached by the plow. In such places fragments of the material are 
scattered over the surface and intermingled with the soil material. 
Throughout the type there are occasional small stony areas in which
