261). Timber is the principal product of our conifers. At present more than three fourths of the timber supply of the United States is furnished by various conifers, especially pines. Dur- ing the early history of this country the white pine (^Finus strobus) was almost our only important soft wood. Now the long-leaf pine (^Pinus palustris), the loblolly pine (Finns tceda) of the southeastern states, and the bull pine {Finns ponder- osa') of the Pacific coast and the Rooky Mountain region are la...rgely utilized. Other important coniferous timber trees are two eastern species of true spruce (Ficea'), the western Douglas fir (Fig. 262), two other western firs (^Abies'), and the southern bald cypress QTaxodiurn). Considerable redwood (^Sequoia semper- virens') lumber is made, though preservation of redwood for- ests is limiting their output. The cypress, larch, and most of the cedars, because of their durability, afford highly valuable timber for all kinds of out-of-door work, especially for posts and railroad ties.
