including good drying, together with aggressive 
merchandising, will partly remedy this situation. 
The cut of timber in all ownership and economic- 
availability classes in the period 1933-62 is assumed 
to total about 30 billion feet. Offset in part by 
growth, this depletion would reduce the 1933 
supply of 36.6 billion feet on lands other than 
national forests to 14 billion feet and the 16.4 
billion feet on the national forests to 13.1 billion 
feet. During 1953-62 the annual cut of national- 
forest timber is assumed to average about 13 
percent of the total annual cut. 
The industrial development in this district is 
dased almost entirely upon the forest industries. 
Prompt application of forestry practice that will 
insure a continuous flow of raw material is of utmost 
concern to all communities in the district. 
COLUMBIA RIVER DISTRICT 
In 1925-34 the Columbia River district produced 
annually an average of 1.77 billion feet of lumber, 
with a high of 2.38 billion feet in 1928 and a total 
of 1.36 billion feet in 1935. The quantity of logs 
cut in this district averaged more than 1.82 billion 
feet in 1925-33, but was only 1.41 billion feet in 
1933. The 1925-33 average was about 23 percent 
of the regional average for that period, and the 
total in 1933 was 30 percent of the regional total. 
Production of both logs and lumber fell off less, 
proportionally, during 1931-33 in this district 
than in any other district. 
The standing timber in this district now in 
availability class I is not sufficient to maintain the 
1925-33 rate of log production until 1963. During 
the decade preceding 1935 the sawmills in the dis- 
trict cut 14 billion feet or logs per year; if this rate 
of production continues, and if the pulp mills in 
the district continue to utilize between 300 and 350 
million feet of logs per year, the sawmills and ply- 
wood industry will be pinched for raw material 
sometime between 1943 and 1952. It is assumed 
here that the annual rate of cutting depletion will 
be only slightly less in 1933-42 than in the period 
preceding 1933, that in 1943-52 it will average 
between 85 and 90 percent of the 1925-1933 rate, 
and that after about 1952 it will diminish abruptly. 
A relatively small number of companies own a 
large part of the timber in this district. It is as- 
107 
sumed that during 1933-42 these owners, both 
large and small, will continue cutting at the same 
rates as in earlier years, but that by the end of that 
decade most of the present small owners will have 
cut out and that by 1945-50 there will be few 
areas where small independent loggers can operate. 
The anticipated reduction in cut of timber in the 
district within the decade 1943-52 would not nec- 
essarily result in a proportional reduction in quan- 
tity of raw material available to the local wood- 
using industries; there is every reason to believe 
that it would be compensated by an increase in 
the quantities of logs brought into the district 
from the Oregon coast and Willamette River dis- 
tricts. In the competition with the Puget Sound 
and Grays Harbor districts for these logs, the 
Columbia River district should have the geographic 
advantage enabling it to intercept the flow of logs 
northward. The lessening of the volume of logs 
cut within the district would probably have some 
effect on the volume and quality of logs available 
on the open log market. This effect would prob- 
ably be felt first in the plywood industry. General 
application of selective logging would conserve the 
supply of peeler logs. 
WILLAMETTE RIVER DISTRICT 
The Willamette River district has not played a 
prominent part in the West Coast lumber industry 
in the past, but seems destined to do so in the future. 
In 1934 more than 515 million board feet of lum- 
ber was sawed in the district. This was 12 per- 
cent of the regional total, and exceeded the out- 
put of any of the other districts except the Puget 
Sound and Columbia River. During 1925-33 the 
annual cut of trees of sawlog size for all uses aver- 
aged about 778 million feet, of which the sawlog 
cut was about 692 million feet, log scale, including 
some 120 million feet shipped elsewhere for manu- 
facture. Cutting in the 30 years 1933-62 is as- 
sumed to average higher per year than in 1925—33, 
but leaving more than 20 billion feet of timber of 
availability class I in the district, even if none of 
the timber now in availability class II moves into 
class I. 
Decadal cuts assumed for this district are as 
follows: 1933-42, 7.6 billion feet; 1943-52, 14.2 
billion feet; 1953-62, 16.2 billion feet. The cut on
