PRESENT FOREST. 9 
Longleaf Pine greatly predominates in the seedling growth on the 
ry sands which constitute Longleaf Pine land; it occurs both singly 
nd in small scattered groups. On this type, seedlings of the Loblolly, 
“Cuban, and Pond Pine are generally confined to abandoned fields 
where the turning under of the inflammable grass has afforded com- 
_ plete protection from fire for a time sufficient for the seedlings to have 
established themselves, and to have grown large enough to survive the 
light ground fires. 
_ At once the most interesting and the most valuable of the second 
growth on Longleaf Pine land are the numerous groups of Longleaf 
_ Pine saplings and poles. These have sprung up in windfalls and other 
‘openings in the old forest, and, on account of the small size of the 
trees, have escaped the lumberman and the turpentine gatherer. 
They are important as forming a nucleus for the future forest on 
Longleaf Pine land. (Pls. V and VI.) To show the actual growth of 
these groups, all trees 1 inch and over in diameter at breastheight 
were counted and calipered on a small number of sample plots. The 
average diameter for each plot was determined, and one or more sam- 
ple trees of this diameter and of normal development were felled. 
Measurements of these sample trees were used as the basis for com- 
puting the total volume and the growth per acre. A summary of 
these sample plots is given in the following table. The results show 
a highly satisfactory rate of growth, in spite of the unfavorable condi- 
tions, incident to frequent fires, under which it was made.
