This is the best American pine imported for indoor work. It is clean and very soft, the annual ring is very indistinct, and the medullary ray is invisible. The sap-wood is a greenish-grey colour, and is worthless. This wood can be obtained in large sizes and very often remarkably free from knots, which, when they occur, are usually large and 'dead' (loose).

This pine can invariably be distinguished by the unique characteristic of numerous short, fine, hair-like streaks in the direction of the fibres; it is useless, or nearly so, in any wet situation, but is fairly durable in dry positions. It holds glue very well, and as it is not liable to warp or twist, is used as backing for veneers. For the same reason it is used by pattern makers. It is easy to work, but is not sufficiently tenacious to hold nails well.
