Probably one-half of this type is cultivated. The remainder is covered with a growth of scrub oak, pine, and some cedar. The soil is thin and only fairly productive, and consequently is not greatly desired for agriculture. It is very easy to work, but has to be cultivated carefully to avoid washing. The crops raised are corn, wheat, grass, and some apples. Corn yields from 25 to 35 bushels, wheat from 12 to 15 bushels, and clover and timothy hay from 1 to 2 tons per acre. Small fruits and vegetables do well. Although naturally a thin soil, the Cecil silt loam is fairly well adapted to the production of the crops just named. Of the small fruits, peaches, plums, and berries do best. On the whole the type is considered much better adapted to wheat than to corn. It is limed and fertilized to a considerable extent, and responds well to such applications. _Cecil Mica Loam._ The Cecil mica loam consists of 12 inches of a friable, micaceous yellow or yellowish red loam, underlain by a yellow or yellowish-red loam, whose mica content increases with the depth until at 24 to 30 inches the subsoil is little more than a mass of small mica flakes which gives it a loose texture. Occasionally the subsoil is a clay loam for several inches before grading into the unweathered mica particles. On the surface there is from 5 to 40 per cent of angular quartz fragments, ranging from 1 to 6 inches in diameter, some being much larger. The Cecil mica loam occurs as one long, narrow strip, occupying the lower, gentle eastern slopes of the Catoctin Mountain. The southern end of the strip begins a short distance north of Leesburg, and extends in a northeasterly direction to the Potomac River, opposite Point of Rocks, Md. The topographic features of the Cecil mica loam consist of gentle and occasionally steep rolling slopes. The surface is well drained and on the steeper slopes the soil washes badly and deep gullies are formed. In a season of moderate rainfall the soil and subsoil retain considerable moisture, but in dry weather crops suffer from drought. No farms are found entirely on the Cecil mica loam, but those farms of the Piedmont, extending up the mountain slopes, generally include some of this soil. Such areas are often farmed, but more generally used as 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._
