Lodgepole Pine (Pinus contorta) 6 
Other names in use. — Scrub pine, knotty pine, Bolander's pine, Henderson's 
pine, tamarack, prickly pine, white pine, black pine, spruce pine, jack pine, and 
bird's-eye pine. 
Range. — From Alaska (Yukon River) southward in the Pacific coast region to 
California (Mendocino County) and through interior British Columbia, the moun- 
tains of Washington and Oregon to California (Sierra Nevada to San Jacinto Moun- 
tains) ; plateau east of the Rocky Mountains (latitude 56°) and south through 
the Rocky Mountain Region to New Mexico and northern Arizona. 
Oven-dry weight per cubic foot, green volume. — 24 pounds. 
Fiber length. — 2.3 mm. 
By Sulphite Process 
Reduces readily. 
L T nbleached pulp: Of excellent color, fine fibered and very strong; probably 
somewhat pitchy; easily bleached. 
Yields: 45 to 50 per cent. 
Bleach required: 10 to 20 per cent. 
Uses to which pulp is suited: News, wrapping, book, and high-grade printing 
papers. 
By Sulphate Process 
Reduces readily. 
Unbleached pulp : Very strong. 
Yields: 45 to 50 per cent of strong pulp. 
Bleaching characteristics probably similar to those of jack pine. 
Uses to which pulp is suited: High-grade kraft wrapping papers and fiber 
board. 
By Mechanical Process 
Reduces readily. 
Pulp: Of excellent color and standard strength. 
Power required: 15 to 25 per cent more than for white spruce. 
Uses: Practically all uses requiring ground wood. 
Note. — The properties stated above apply to the lodgepole pine grown in the 
Rocky Mountain regions, which contains much less pitch than that grown in the 
lowlands and coastal regions. The pulping properties of the latter are similar to 
those of jack pine. 
Long-leaf Pine (Pinus palustris) 
Other names in use. — Long-leaf yellow pine, southern hard pine, southern 
heart pine, hill pine, Georgia pine, Florida pine, Texas yellow pine, North Carolina 
pitch pine, long-leafed pine, longstraw pine, southern yellow pine, fat pine. 
The lumber is usually called "pitch pine" in the export trade. 
Range. — Atlantic coast region from southeastern Virginia to southern Florida 
and westward to eastern Texas; northward in Alabama to the northern part of 
the State, to northwestern Georgia, central and western Mississippi and western 
Louisiana almost to the northern border of the State. 
Oven-dry weight per cubic foot, green volume. — 34 pounds. 
Fiber length. — 3.7 mm. 
By Sulphite Process 
Long-leaf pine varies enormously in pitch content, and although selected trees 
might be used, it would be inadvisable to consider the use of this species on a 
commercial scale. 
By Sulphate Process 
Reduces readily. 
L'nbleached pulp: Strong, rather coarse, and very long fibered; requires 
special beater treatment to develop maximum strength. Strength is usually 
sacrificed to secure standard formation of sheet. 
Yields: 45 to 50 per cent of strong pulp, 40 to 45 per cent of pulp for bleaching. 
6 The Rooky Mountain form of this tree, upon -which the following tests were made, was formerly and is 
still designated variously as Pinus murrayana, P. contorta var. murrayana. and P. contorta var. latifolia, 
the Pacific coast form being restricted to P. contorta. The Rocky Mountain form contains much less pitch 
than that from the lowlands and coastal regions. The properties of the lowland and coast form are approx- 
imately as given for jack pine.
