348 BOTANICAL SURVEY OF DISMAL SWAMP KEG ION. 



which is found efficacious in tnosl rases. Those who deny thai Ihis 

 treatment is beneficial have probably been too i inpatient, and have 

 not allowed sufficient time for the chemical changes by which the 

 acid is neutralized. 



DESCRIPTIONS AND ANALYSES OF SAMPLES. 



The descriptions and analyses of a series of samples taken from 

 typical soils of The Plain will show better than any general discus- 

 sion which are and which are not best suited to truck and other 

 crops. Pour samples from Newbern, N. C, are added to those from 

 the Dismal Swamp region for purposes of comparison. 



Beginning at the north and taking the samples as they occur in geographic order, 

 going south, we have first sample No. 1599, which is a subsoil at from 12 to 30 

 inches, from Baliantine's farm near Eastern Branch, Norfolk. Va. It contains 

 14.35 per cent of clay, and while considered a good truck soil, is too heavy in 

 texture to be as early as some other soils of the region. 



Sample No. K501 is also a subsoil at from 12 to 30 inches from the same farm, 

 but is from land that needs drainage. Its texture is better suited for early truck 

 than is No. 1599, because it contains little more than half as much clay. If drained 

 it should make good early truck land. 



Sample No. 1598, from the farm of William Wise, and No. 1595, from Henry 

 Kirn's farm, are subsoils at from \) to 30 inches, both from near West Norfolk. Va. 

 They represent what is known as the finest type of early truck land, and it will 

 be well to note carefully their texture. They are quite similar and contain about 

 H per cent of clay and from 20 to 25 per cent of silt, the rest being largely medium 

 and tine sand. 



No. 1579, from the thirty-fifth milepost. Currituck County, N. C, represents 

 the subsoil characteristic of the clay lands in that vicinity. It contains about 25 

 per cent of clay and is therefore much t >o heavy for truck. It would do well 

 for corn, wheat, and pasture land, 



No. 1570 is a sample from Camden. Camden County, N. C. It is a light sandy 

 soil well suited to medium and late truck. 



No. 1571 is also from Caniden and represents the texture of the clay at 4 feet in 

 depth, which underlies all of the Elizabeth City lands. 



No. 15(«i is a subsoil at from 9 to 30 inches and is from the farm of Dr. E. F. 

 Lamb, Elizabeth City, Pasquotank County, N. C. This soil is well suited to truck. 



Nos. 1511) and 1520, subsoils at from 7 to 24 and 24 to 30 inches, respectively, are 

 very similar in texture. They are too heavy for any but late truck. Owing to 

 their proximity to the river they are exceptionally free from frost. 



No. 1510 is from 2 miles south of Chapanoke, Perquimans County. N. C. It is 

 a heavy, stiff, close, tenacious, wet subsoil underlying a deep black loam. It con- 

 tains over 25 per cent of clay and is therefore not suited to truck. It would make 

 good grass and wheat land. 



No. 1542 is a subsoil from one mile south of Chapanoke. N. ('..and is much lighter 

 in texture than the preceding sample. It would probably be well adapted to truck. 



No. 1558 is from No. 4, Leighs farm, near the point, Durants Neck, Perquimans 

 County, N. C. It is a subsoil of from 9 to 30 inches, and contains 22 per cent of 

 clay and 30 per cent of silt. It is too heavy for truck, but is well suited to corn, 

 wheat, and cotton. 



No. 1534 is a subsoil at from 5 to 30 inches, and is from the farm of S. S. Woods, 

 at Hertford. Perquimans County, N. C. It contains GA percent of clay and 70 

 per cent of fine sand, and would be well adapted to early truck.
