and common names). Bastard Pine, Meadow Pine 



Pitch Pine, She Pine, She Spruce Pine 



Pitch Pine (Ga., Fla.). 

 Locality. 



Coast region, South Carolina to Florida and Louisiana. 

 Features of Tree. 



Fifty to eighty feet in height, one to two feet in diameter. 

 Color, Appearance, or Grain of Wood. 



Resembles loblolly pine. Dark straw with tinge of flesh color. 

 Variable and coarse appearance in cross section. Annual rings 

 are usually wide (10 or 20 per inch). 



Structural Qualities of Wood. 



Similar to those of longleaf and of selected pieces of loblolly 



pine. Sometimes more resinous than longleaf pine. 

 Representative Uses of Wood. 



Similar to those of longleaf pine, from which it is seldom separated. 

 Weight of Seasoned Wood in Pounds per Cubic Foot.

 Modulus of Elasticity. 



2,370,000 (average of 410 tests by U. S. Div. of Forestry).* 

 Modulus of Rupture. 



13,600 (average of 410 tests by U. S. Div. of Forestry).* 

 Remarks 



Resembles and is marked longleaf pine (Pinus palustris), no 

 distinction being made in the lumber. The Cuban Pine 

 supplies large pieces of perfect wood, thus rivaling Loblolly 

 Pine (Pinus toeda) with which it has probably been confused. 

 The structure of the wood closely resembles that of Loblolly 

 Pine. Trees reproduce rapidly, those forty years old are often 

 large enough to be tapped ; this is important, because of 

 the fact that Longleaf Pine from which "naval stores" are 

 principally obtained is being destroyed so rapidly. The very 

 heavy, fresh wood shrinks considerably, although with small 



- injury, during seasoning. The Cuban Pine grows in the sub- 

 tropical regions of the United States and in Hondurus and 

 Cuba, whence the name.
