“Norfolk fine sandy loam,’’* ‘‘ Norfolk sandy loam,” “Swamp,” 
“Norfolk sand,” ‘Portsmouth fine sandy loam,” ‘Portsmouth 
sand,” “Portsmouth sandy loam," and ‘‘ Norfolk fine sand"; and 
in the South Carolina portion “ Norfolk sandy loam,” “Swamp,” 
“Portsmouth sandy loam,” ‘Norfolk sand,”’ ‘‘Coxville fine 
sandy loam,” ‘‘Norfolk fine sandy loam,” ‘Portsmouth fine 
sandy loam,” and ‘‘ Orangeburg fine sandy loam.”’ This sequence 
should not be taken too literally, for the areas that have been 
surveyed may not be perfectly typical, and moreover, there are 
all possible gradations between adjacent soils, and: similar soils 
are very liable to be classified a little differently by different 
men in neighboring areas, or even by the same men in dif- 
ferent years. But it will suffice to show the prevalence of gray 
sandy loams and of swamps, and the scarcity of reddish and 
distinctly clayey soils. The reddish “Orangeburg” soils are 
perceptibly commoner in South Carolina than farther northeast. 
The physical composition of the soil may also be illustrated by 
disregarding the more or less arbitrary series names (thus elimi- 
nating much of the ‘ personal equation’’) and summing up the 
ten commonest texture classes, with their percentages. As in the 
plant list farther on, the column of percentages preceding the 
names is for the whole area, and the others for separate states as 
indicated.

* Ror the benefit of readers who are not familiar with the system of classification 
used by the U. S. Bureau of Soils it should be explained that the ‘ Norfolk” series 
includes grayish coastal plain soils with friable yellowish subsoils, the ‘‘Orangeburg” 
gray, red or brownish soils with sandy clay subsoils, and the “ Portsmouth” fide 
blackish more or less peaty soils with flat or slightly depressed surface. “Swamp” 
is usually applied to permanently saturated soils, but does not include all kinds of 
swamps, some of which have been described under other names, especially in later 
years,
