States, but the past and present total annual production of "yel- 
low pine," including longleaf, shortleaf, loblolly, and several species 
of minor importance, far exceeds the yield of Douglas fir. The wood 
of Douglas fir is quite similar to that of longleaf pine in many of its 
properties and uses. It is sold under the name of Douglas fir, 
Oregon pine, red fir, yellow fir, Douglas spruce, Washington fir, Ore- 
gon fir, and locally in California as spruce.

OAK. 
The several commercial oaks furnish the largest quantity of any 
kind of hardwood lumber. The general lumber trade calls all oak 
lumber either white or red oak. These trade names are based on the 
appearance of the two general kinds of lumber cut from oak trees 5 
white oak lumber being light in color and dense and red oak lumber 
being somewhat reddish and porous. Since these two kinds of lum- 
ber are supplied by distinct groups of botanical white and red oaks, 
the trade distinction is logical. The bulk of oak lumber is cut from 
less than a dozen species. The largest part of the oak lumber is 
furnished by white oak and red oak, chestnut oak and Texan red 
oak being of next importance. Following k a list of the principal 
commercial oaks, divided into two groups. 
WHITE oak: 
White oak (Querents alba) is the white oak common throughout 
the eastern half of the United States. 
Chestnut (or rock) oak (Quercus prinus) occurs in the Appa- 
lachian Mountain region. 
Post oak (Quercus stellata) and bur oak (-Quercus macrocarpa) 
have about the same range as white oak, but are not so abundant. 
Overcup oak (Quercus lyrata) and cow (or basket) oak (Quercus 
michauxii) are the most important of the southern white oaks.
