The tree attains a height of from forty to eighty feet and a diameter of three. This pine is not found in extensive forests, but in scattered patches, nearly always on poor soil where other trees will not crowd it. Light and air are necessary to its existence. If it receives these, it will fight successfully against adversities which would be fatal to many other species. In resistance to forest fires, it is a salamander among trees. That is primarily due to its thick bark, but it is favored also by the situations in which it is generally found--open woods, and on soil so poor that ground litter is thin. It is a useful wood for many purposes, and wherever it is found in sufficient quantity, it goes to market, but under its own name only in restricted localities. Its resinous knots were once used in place of candles in frontier homes. Tar made locally from its rich wood was the pioneer wagoner’s axle grease, and the ever-present tar bucket and tar paddle swung from the rear axle. Torches made by tying splinters in bundles answered for lanterns in night travel. It was the best pine for floors in some localities. It is probably used more for boxes than for anything else at present. In 1909 Massachusetts box makers bought 600,000 feet, and a little more went to Maryland box factories. Its poor holding power on spikes limits its employment as railroad ties and in shipbuilding. Carpenters and furniture makers object to the numerous knots. Country blacksmiths who repair and make wagons as a side line, find it suitable for wagon beds. It is much used as fuel where it is convenient.
