is carried on, and the intervals between the gaps are subdivided 
by numerous ravines into more or less widely separated spurs and 
knobs. The southern slopes are covered with the remains of great 
forests of this valuable timber, interspersed with various hard- 
wood trees and with shortleaf pines (P. virginiana and P. echinata). 
Fic. 1.—Young longleaf pines reforesting mountain side after removal of ripe timber 
They have repeatedly been cut for lumber and burned over by 
“round fires” started in spring by farmers to provide a free 
range for their cattle, but the longleafs continue to reproduce them- 
selves with a pertinacity which, if not too diligently thwarted by 
the blundering incompetence of county officials and the short- 
sighted greed of ignorant timber cutters, will in the course of 4 
generation or two repopulate the southern mountain slopes with a 
new forest growth sprung from the old stock (fig. 1).
