THE SOUTHERN CYPRESS. 57 
LOW VALUE OF LAND AND GROWING STOCK. 
It has been shown (p. 52) that uncleared and undrained lands 
covered with stumps and a mass of surface roots are of low and 
generally uncertain value, and that the cost of draining and clearing 
is somewhat more than the present value of similar cleared and 
drained lands. The actual present value of the timber left on the 
land after conservative cutting is very small compared with its 
potential value. 
The figures given in Table 15 apply to the cypress in a typical mixed 
cypress and hardwood stand, cutting an average of approximately 
12,500 board feet of cypress per acre. This is a safe average for 
medium mixed cypress, since pure cypress often cuts from 15 to 25 
thousand board feet over large areas. It should be noted that the 
volume of the trees 16 inches and over in diameter constitutes 94 per 
cent of the stand. By cutting to a diameter limit of 18 inches, the 
amount of merchantable timber left standing on the average will 
likely amount to between 8 and 10 per cent of this particular stand. 
In other stands not so well stocked with younger classes it will be less.

1 Cypress in mixture with hardwoods (about one-third of the latter); 21 trees per acre of cypress 16 inches 
and over in diameter. Representative of large tracts in Florida and Louisiana. 
In the above representative stand with a good stocking of young 
trees, 5.7 per cent of the volume is contained in the trees from 11 to 
15 inches in diameter. <A diameter limit of 16 inches in this stand 
would mean leaving approximately 750 board feet, or a value of 
$3.75, at an average stumpage rate of $5 per thousand feet. The 
combined value of land and timber left in cutting to a 16-inch diameter 
limit will probably average generally between $4 and $7 per acre. 
Lumbermen in very many cases fail to consider fairly the very low 
relative stumpage value of timber in the small sizes. Small trees 
obviously are utilized at relatively little profit, or often at a loss,
