Charles H. Snow, The Principal Species of Wood: Their Characteristic Properties
“ The longleaf pine (Pinus palustris) is distinctly the most important of its group. The wood is ideal for heavy constructions. Beams, docks, trestles, and frames of cars are formed of it. The trees afford the greater bulk of turpentine, tar, and resin, or "naval stores," produced in this country. [74] Cuban, shortleaf, and loblolly pine woods (P. heterophylla, P. echinata, and P. tæda) are nearly similar. Longleaf and Cuban pines are seldom separated, while shortleaf and loblolly pines are also mixed. Longleaf pine usually affords finer structure and more heartwood than Cuban pine. ”
