Nebraska, 24,640 acres. These soils are highly valued for 
the production of celery, onions, peppermint and cab- 
bage. 
47. Piedmont plateau. — This area lies between the At- 
lantic ‘Coastal Plain and the Appalachian mountains and 
extends from the Hudson river to east-central Alabama. 
The land is gently rolling to hilly. The sand (259,744 
acres in Georgia, North Carolina, South Carolina and 
Virginia) “is especially adapted to sweet potatoes and 
watermelons.” 
48. Appalachian mountains and plateau.— The loams, 
gravelly loam, sandy loam, and fine sandy loam of the 
DeKalb series are well adapted to vegetables. There are 
760,266 acres of these types. 
49. Limestone valleys and uplands. — Limestone soils 
are not generally regarded as good truck soils, although 
they often produce excellent results. Cantaloupes are 
grown on silt loam in the Highland river region of Ten- 
nessee. The fine sandy loam of the Cumberland series is 
adapted to vegetables. The silt loam of the Decatur 
series is especially well adapted to cantaloupes. A variety 
of late garden crops is grown successfully on the 
Hagerstown series. 
50. Glacial and loessial regions. — U. S. Bureau of 
Soils, Bui. 55, p. 143: “North of a line passing through 
northern New Jersey, northwestern Pennsylvania, 
southwestward through Ohio to Cincinnati, crossing the 
Mississippi river at St. Louis, following the south side 
of the Missouri river into Montana, where it crosses the 
Canadian boundary line, then dips southward into Idaho 
as a long' lobe in the mountainous nonagricultural region, 
and crosses the northwestern part of Washington, in- 
cluding the Puget Sound region,” there are 8,057,686 
acres of glacial and loessial soils. 
51. Marshall series. — Of sand and fine sand, there are 
107,008 acres. These types are well adapted to truck crops,
