the swamp in this part of it, is between 1 and 2 miles wide, and is suc- 
ceeded by half a mile of reeds, and towards the central part becomes 
higher, sandy, briary and poor.

Number 11 is a sample of low flat land, a sort of second swamp, char- 
acterized by a growth of willow, oak, pine, black and sweet gum ; it is 
light gray in color, and of a quite fine texture, so that it has the appear- 
ance of clay ; and is of good quality. Number 12 is the subsoil, and as 
will be seen, supplies some substances which are deficient in the soil it- 
self, and suggests deep plowing as a means of renovation. There is a 
large quantity of land throughout the eastern region, which answers to 
the above description. The sample was obtained from the woods on the 
plantation of L. A. Mewbern, 7 miles from Kinston.
