GEOLOGY OF NORTH CAROLINA- 
taken, represents a large proportion of it. E is given by Emmons as aft 
example of the better kind of gallberry land,, of considerable extent in 
Onslow. The coloris described as “Tight yellow and texture line.” This 
soil has a fair proportion of alumina and iron, in which this class of land 
is usually deficient, and no excess of organic matter as is common. So 
that it differs much from a true gallberry soil, which consists essentially 
of a coarse white sea sand with organic matter and little else, and is rep- 
resented by the analyses D and E. These gallberry tracts are generally 
flat and wet, and are characterized by a dwarfed vegetation as well as by 
the prevalence of the bash from which they are named.

Number 31 represents the Burgaw Savannah 
in the 
northern part of 
New Hanover county, on both side 
s of the railr 
oad, 25 
miles above Wil- 
mington. This i 
sample was 
taken 
within, half 
a mile 
of the 
upper or 
northern margin. 
The soil 
is dark 
gray to black colored to tin 
e depth of 
about a foot, and 
is composed of ' 
very fine sar 
id with 
little May, but is 
pasty when wet, 
with impalpable h 
limns, which 
renders 
i it as i i 
npervious 
to water as pipe clay. At the depth of two feet the color is light yellow, 
and at three feet the quantity of clay is considerably increased. 32 is 
another sample from the middle of the same sav. nnah. It contains more- 
sand and organic matter, and much less clay than the former. It is ob- 
vious from these analyses that this is a fair soil, and if drained, marled 
and aerated, it would no doubt produce well. The growth consists of a 
number of species of short grasses with sarracenias and other flowering
