In the western part of the block the topography is rolling. There 
is little or no rock. The soil is a pure sand, very deep and dry. The 
water courses are mostly intermittent, flowing only during seasons of 
wet weather. In consequence the proportion of creek type on this 
block is small, and the longleaf pine is often found growing in the 
hollows as well as on the slopes and ridges. The stand of longleaf 
pine is pure and there is very little hardwood undergrowth. It is on 
this part of the tract that the longleaf pine reaches its best develop- 
ment. (Compare Table XIX.) 
Toward the east, with the appearance of the sandstone, the topog- 
raphy becomes gradually rougher, the slopes steeper, and the ridges 
more sharply defined. On the westerly and northerly exposures hard- 
woods and a few loblolly and shortleaf pines sometimes occur in mix- 
ture with the longleaf. Of the last, trees of the smaller diameter 
classes, namely, under 15 inches in diameter breasthigh, are somewhat 
more common than in the western part of the block. In the northern 
part of the block, during the past few years, timber has been cut and 
taken out to the railroad from the following forties: 
Section 9—NW. of NE.; NE. of SE.; SE. of NW.; SW. of NW. 
Section 1O—NE. of NE.; SE. of NE. 
Section 11—SE. of SE. and all of SW. except SW. of SW. 
The cutting has been to diameter limits of from 15 to 16 inches. 
In section 9, owing to the lack of trees of the smaller diameter 
classes, the logging has resulted in a clean cut, but in sections 10 and 
11, where the proportion in the stand of trees under 15 inches is 
unusually large, the cutting has simply removed the largest and best 
timber, which was pretty evenly distributed among the small stuff, 
and the forest would have been left in a good condition to produce a 
second crop if it had not been for the slash fires after the logging, 
which in some places have killed all the pines left standing. The 
area, however, which has been damaged by the logging and slash 
fires is comparatively small, and the average stand and yield per acre 
is good, as is shown in the follomanc tables.
