i Data for sawlog production are averages for the period 1925-36; other data are for 1930 only. 



' Figures given are log scale, based on Scribner rule. 



3 In addition to the quantities of material shown under this heading, considerable quantities of slabs, edgings, mill waste, and sawdust were used as 



fuel. 



depletion, given in table 13, account for an average 

 of 1.26 billion board feet in trees of saw-timber size 

 and 2.2 million cubic feet of small trees removed 

 annually from the forests as sawlogs or as minor 

 products, such as fuel wood, fence posts, poles, 

 and piling. The portion of the tree left in the forest 

 by cutting operations was not included since the 

 saw-timber inventory statistics and growth calcula- 

 tions included only the usable portion of the tree. 

 The annual output of sawlogs was classified by 

 species, State, and forest-survey unit, and that of 

 the minor products by item, species, State, forest- 

 survey unit, and size class of the trees from which 

 the material was cut, whether of saw-timber size 

 (11.1 inches d. b. h. or more) or of less than saw- 

 timber size. 



Sawlog Drain 



The 1.1 billion board feet of sawlogs produced 

 annually during 1925-36 (table 14) amounted to 

 about 87 percent of the total cutting depletion. 

 The cut was large during the first half of the 12- 

 year period; in only one year, 1927, did the volume 

 fall below 1 billion board feet and in 1929 1.4 

 billion was cut. A decrease in the second half of 

 the period reached a low of 565 million board feet 

 in 1932, but subsequently a rapid rise carried the 

 total to 1.5 billion board feet in 1936, the high 



point for the period. During 1937 production 

 reached 1.6 billion board feet, dropped to 1.3 in 

 1938, but advanced to an all-time high of 1.8 

 billion in 1939. 



Approximately 77 percent of the average annual 

 sawlog cut was in Oregon. The trend in this 

 State followed very closely that for the region, the 

 peak being reached in 1936 and the low point in 

 1932. In eastern Washington the peak was 

 reached in 1929, at an 18 percent increase over 

 the 1936 cut. Figure 20 shows the average 

 annual sawlog production in the region during 

 1925-36 by forest-survey unit. 



The Klamath Plateau unit led during the period 

 in the volume of sawlogs produced, reaching to 

 nearly half of the average annual output in Oregon. 

 The unit contains two of the most active lumbering 

 centers in the region, Klamath Falls and Lakeview. 

 Large-scale lumbering began in the Klamath Falls 

 district about 1924 and in the Lakeview district in 

 1929. By 1936, the end of the period studied, pro- 

 duction exceeded 600 million board feet and was 

 still increasing. Because of the large supply of 

 accessible ponderosa pine timber in the unit the 

 output of logs will probably average over half a 

 billion board feet annually for the next two 

 decades, unless restrictions in the sale of Federal- 

 owned and Indian-owned timber and the adoption
