The survey of cutting depletion covered the ma- 
terial removed from the forest for different uses, 
not only as sawlogs but also as minor timber prod- 
ucts, such as fuel wood, poles, piling, posts, veneer 
blocks, shingle bolts, pulpwood, mine_ timbers, 
hewed ties, and excelsior bolts. Sawlogs were clas- 
sified by species and geographical unit; the minor 
timber products were classified by item, species, 
and geographical unit, and according to whether 
the material was cut from trees of saw-timber size 
(16 inches d. b. h. or more) or from smaller trees. 
The results were expressed in board feet for the 
saw-timber size and in cubic feet for the smaller 
trees. The average annual timber production in 
the Douglas-fir region is shown in table 11 by State 
and survey unit. 
The total volume of material cut from trees of 
sawlog size annually during the period 1925-33 
averaged 7.9 billion board feet. The area clear- 
cut annually during that period amounted to 
roughly 165,000 acres. By far the greater part of 
the cutting, in terms of area, was in large old- 
growth Douglas-fir. Cutting is heaviest in the 
north Puget Sound, central Puget Sound, Grays 
Harbor, and Columbia River, Oreg., units. 
Sawlog Production 
Sawlogs comprise about 95 percent of the total 
cutting depletion. The average annual sawlog 
production during the period 1925-33 of 7.4 
billion board feet, log scale, is distributed by 
species for each unit in western Oregon and western 
Washington in table 12. During the first part of 
this period annual sawlog production increased, 
but beginning with 1930 it declined rapidly, so 
that in the 4 years 1930-33 it was little more than 
half as much as in 1925-29. 
More than two-thirds of the region’s total output 
of sawlog volume during 1925-33 was produced in 
Washington. Douglas-fir composed 83 percent of 
the sawlog production in Oregon, and 68 percent 
of that in Washington. Other leading species, in 
order, were western hemlock, western redcedar, 
and Sitka spruce. 
By far the greater part of the sawlog production— 
6,592 million board feet annually—took place on 
private land. The remaining 835 million board 
feet was distributed, in million board feet, as 
255, Oregon & 
California Railroad revested grant lands, - 245; 
State lands (all in Washington), 175; and Indian- 
owned lands, 160. This volume on public or In- 
dian lands was all cut by private concerns to which 
the stumpage had been sold. 
Water transportation has been a significant 
factor in the development of the lumber industry 
in the Douglas-fir region. ‘The units leading in saw-
