fine sandy loam, representative of the heavier phases of this type. This soil 
occupies level to undulating areas, which are only fairly well drained, and open

This is a yellow, firm, but friable fine sandy loam. There is a layer of pale-

Mixed with the silt and clay is a small percentage of the finer sand grains. 
The soil is mellow and loamy and does not ordinarily form clods. It contains

quartzite, with some shale, limestone, and red sandstone. Topography mod- 
erately rolling and surface drainage good.
