posed about 85 percent of the timber burned and 
40 percent of this was in trees 50 inches d. b. h. and 
more. By the time the county may be expected to 
own most of the burned timber the gross volume of 
the unsalvaged trees 50 inches d. b. h. and more 
will probably be less than 3 billion feet. 
In an examination '* of a large area of the burn

large parts of the burn. 
The profits in salvaging this burned timber, even 
at very low valuation of stumpage, have been 
small. An operator whose margin of profit is 
narrow is not likely to do much work to prevent 
spread of slash fires from the areas logged. As 
time goes on, salvage operations will probably be 
conducted only by smaller operators who will 
spend even less time and money on control of slash 
fires. 
SOUTH OREGON DISTRICT 
The south Oregon district contains about 89 
billion feet of standing timber, of which about 25 
billion feet is rated in availability class I. In the 
period 1925-33 the cut of logs in the district 
amounted to about 1 percent of the regional total, 
practically all manufactured locally as lumber— 
a few logs cut along the north border being sent 
to the Willamette River district for manufacture. 
During the period 1925-34, the average annual 
production of lumber was only about 85 million 
feet, of which more than 90 percent was produced 
in the Rogue River unit, and 70 percent of this 
was ponderosa pine and sugar pine. 
The depletion assumed in the survey for the 
period 1933-62—even though about six times as 
great a cut of lumber is assumed for 1953-62 as 
the 1933-42—would not materially change the 
quantity of timber available in the district. For

some time to come, also, no considerable quantity 
of logs is likely to be taken from this district for 
manufacture.!® ‘There appears to be sufficient raw 
material on hand not only for existing wood-using 
industries but for a considerable addition to them. 
Several of the small mills may not have enough 
supplies to continue indefinitely in their present 
locations, but most could be relocated without 
difficulty. 
Pulpwood 
At the beginning of pulp manufacture on the 
Pacific Coast, the principal material used by the 
pulp mills was sawmill waste. In 1929, pulpwood 
consumption in the region totaled 1% million 
cords, of which logs constituted 48 percent, saw- 
mill waste 40 percent, and forest pulpwood 12 
percent. Data obtained by circulating a ques- 
tionnaire to all pulp manufacturers in the region 
in 1936 indicated that in a normal year pulpwood 
consumption would total very nearly 2 million 
cords and would be divided as follows: Waste, 11 
percent; logs, 69 percent; and forest pulpwood, 20 
percent. During the last few years the sawmill 
waste used in pulpwood manufacture has de- 
creased greatly in total quantity, as well as in pro- 
portion to other materials used for pulpwood, and 
the quantities of logs and forest pulpwood used for 
this purpose have correspondingly increased. ‘This 
is accounted for in part by the great decrease in 
In Puget 
Sound sawmills, for example, until 1930 hemlock 
lumber constituted about 20 percent of all the 
lumber manufactured, in 1932 it was but 7 per- 
cent of the total, and in 1934 it was a little more 
than 8 percent. After 1930, lumber buyers who 
formerly took a certain quantity of hemlock mixed 
with Douglas-fir refused to take any hemlock. 
However, loggers continued to take approximately 
the same percentage of hemlock out of the woods; 
in fact, of the logs brought out of the woods in 
1931-33 the percent of hemlock was larger than 
in 1925—29; 
Future trends in use of logs as against use of 
forest pulpwood for pulp manufacture are hard to 
hemlock lumber production since 1929.

County will undoubtedly be milled in eastern Oregon, 
probably at Klamath Falls.
