Pumpkin Pine, Soft
Pine). A very large tree, forming extensive forests in the Rocky
Mountains and furnishing most of the timber of the western United
States. It is confined to Oregon and California, and grows at from
1,500 to 8,000 feet above sea level. Has an average height of 150 to
175 feet and a diameter of 4 to 5 feet, with a maximum height of 235
feet and 12 feet in diameter. The wood is soft, durable,
straight-grained, easily worked, very resinous, and has a satiny
luster which makes it appreciated for interior work. It is extensively
used for doors, blinds, sashes, and interior finish, also for
druggists' drawers, owing to its freedom from odor, for oars,
mouldings, shipbuilding, cooperage, shingles, and fruit boxes. Oregon
and California.

=24. Long-Leaf Pine= (_Pinus palustris_) (Georgia Pine, Southern Pine,
Yellow Pine, Southern Hard Pine, Long-straw Pine, etc.). Large-sized
tree. This species furnishes the hardest and most durable as well as
one of the strongest pine timbers in the market. Heartwood orange,
sapwood lighter color, the annual rings are strongly marked, and it is
full of resinous matter, making it very durable, but difficult to
work. It is hard, dense, and strong, fairly free from knots,
straight-grained, and one of the best timbers for heavy engineering
work where great strength, long span, and durability are required.
Used for heavy construction, shipbuilding, cars, docks, beams, ties,
flooring, and interior decoration. Coast region from North Carolina to
Texas.

=25. Bull Pine= (_Pinus ponderosa_) (Yellow Pine, Western Yellow Pine,
Western Pine, Western White Pine, California White Pine). Medium- to
very large-sized tree, forming extensive forests in the Pacific and
Rocky Mountain regions. Heartwood reddish brown, sapwood yellowish
white, and there is often a good deal of it. The resinous smell of the
wood is very remarkable. It is extensively used for beams, flooring,
ceilings, and building work generally.
