 fewer trees per acre.

Table 5 shows a stand of timber on the west slope of the Cas- 

 cades in Klamath County, Oreg. This shows yellow pine in mixture 

 with sugar pine and white fir. Douglas fir forms a large part of 

 the forest here, but disappears farther south as shown in Table 6. 

 Large diameters, occasionally exceeding 60 " inches, are found in 

 all species.
