woodlots. Where cultivated the yields are scant, except where the soil
is heavily fertilized. Corn yields from 10 to 30 bushels per acre and
sometimes more, and wheat from 6 to 12 bushels per acre. The type is
best adapted to forestry, chestnut orcharding, and grape growing.


_De Kalb Stony Loam._

The soil of the De Kalb stony loam consists of a yellow or gray sandy
loam of coarse texture, having an average depth of 12 inches. The
subsoil consists of a heavy yellow sandy loam to a depth of 24 inches
or more, where it rests upon a mass of sandstone fragments. These
sandstone fragments and bowlders occur in varying quantities
throughout the soil and subsoil. Where the fewer stones are found the
soil is not so sandy, but a light loam, yellow or brown in color,
underlain by a deep yellow loam subsoil.

The De Kalb stony loam is a mountain soil, occurring in long, parallel
bands of varying width, extending in a general northeast and southwest
direction, and mainly occupies the crests and slopes of the Blue Ridge
and Short Hill mountains. It also occurs in smaller areas on the crest
and east slope of Catoctin Mountain.

On the Blue Ridge and Short Hills the De Kalb stony loam covers the
whole of the mountains, and here the physiography consists of long,
sharp, rock-crested ridges, with steep, rugged slopes and occasional
cliffs and huge ledges. There are occasional benches on the mountain
sides, and here there is an accumulation of two or three inches of a
black mold, resting on the broken sandstone fragments, and covered
with a growth of locust, oak, and berry vines.
