THE FOREST TREES. 37 
This species sprouts freely from the stump. It is probable that 
much of the young growth is of sprout origin. Seedlings of Pond 
Pine bear partial shade, though not so much as Loblolly Pine. Pond 
Pine is gaining ground in the reproduction. Much of this second 
growth is of the unpromising ‘ Old-field,’ open-stand variety. 
The root system is superficial. In the open the tree develops many 
small branches, and the crown is long. Sprout-like branches often 
grow along the entire trunk. 
SPRUCE PINE AND SHORTLEAF PINE. 
Spruce Pine (Pinus glabra Walt.) and Shortleaf Pine (Pinus echi- 
nata Mill.) occur on these lands, but in small numbers. Spruce Pine 
is confined to the swamps; Shortleaf is found only in the second 
growth on Longleaf Pine land. 
The following tables show the development of Longleaf, Cuban, 
Loblolly, and Pond Pine in total height, clear length, and actual and 
possible merchantable length on a basis of diameter at breastheight 
(45 feet from the ground). Diagrams 1, 3, 5, and 7 are graphic rep- 
resentations of these tables for each species separately.
