THE YIELD BY BLOCKS. 
With the exception of Hell Hole, none of the Cooper River holdings 
are of great area. Within them there are, however, great differences 
in stands of timber and in composition of the forest. For this reason 
the holdings were subdivided into blocks, each of which contains, so far 
as possible, a uniform stand of timber of like composition. No block 
extends from one holding into another, and, when possible to avoid it, 
no swamp land was included in the same block with upland. A com- 
bination of the upland or swamp land blocks in any holding will give 
the total yield of timber on upland or swamp land for that holding, 
and by a combination of those of either kind on all blocks the same 
can be ascertained for the whole tract. 
The yield of timber is estimated for each block separately. Table 
No. V shows the stand in board feet of the most important species 10 
inches and over in diameter breasthigh, by blocks and holdings, and 
Table No. VII shows the same for the whole tract. In order to give 
a more accurate idea of the quality and size of the merchantable timber 
on the tract, the yield of cypress, pines, and yellow poplar is computed 
in Table No. VI for trees between different diameters in each block 
and holding. 
No tables of volume for ash, maple, and hickory being available, the 
yield of these species could not be computed. Table No. VIII gives 
the number of trees of each diameter for these species over the whole 
tract. 
The yield of pine and cypress shown in the following tables is based 
upon the two-thirds log rule, the yield of other species upon the Doyle. 
Table No. LX shows the relation these two rules bear to each other. 
No deduction for cull is made in the tables; this figure can best be 
supplied by the company. 
The map accompanying this report shows the division into blocks 
and also the yield per acre of pines and cypress. The average diameter 
and percentage of longleaf pine, loblolly pine, and cypress is also
