areas occur in close proximity to the larger ones. One of the larger
areas is situated just south of Leesburg, while another occurs east of
Lucketts.

The topography consists of a gently rolling to nearly level plain, and
there are no steep slopes or rough areas. Drainage in this type is
excellent, the easy slopes allowing a gradual flow of water from the
surface without undue erosion, except with very heavy rains on the
steeper slopes. The loamy subsoil allows a ready but not too rapid
percolation of surplus soil moisture, and never gets soggy or in a
cold, sour condition. Numerous small streams extend throughout the
area of this type, allowing a rapid removal of all surplus water into
the Potomac River, the chief drainageway of the County. Along these
streams, which in all cases have cut out beds some 10 to 30 feet below
the surrounding plain, the slopes are gradual.

The original growth on the Penn loam was a forest of oak, hickory, and
walnut, but at the present time nearly all of the type is cleared and
farmed. The soil is not naturally very productive, but is prized on
account of its great susceptibility to improvement, its quick
responsiveness to fertilization, and its easy cultivation and
management. The surface is smooth and regular, and the absence of
stones, together with the loamy texture of the soil, makes it easy to
maintain good tilth. Any addition of fertilizers or lime is
immediately effective, and by judicious management the type may be
kept in a high state of productiveness. Many fine farms with good
buildings are to be seen on this type. The crops grown are corn,
wheat, grass, clover, apples, and small fruits. Grazing, stock
raising, and dairying are practiced to some extent. The land yields
from 40 to 60 bushels of corn, from 10 to 15 or more bushels of wheat,
