. Lumbering in the sugar and yellow pine region of California . cedar produce from25 to 31 per cent. In sugar and yellow pine stands the pine commonlycuts from 32 to 45 per cent uppers, yellow pine alone from 30 to 45per cent, and sugar pine from 35 to 55 per cent. A comparison of the lumber grades produced from sugar andyellow pine may be made from Table 2, which shows the results oftwo mill tallies made by the Forest Service during the season of first of these was for 2,230 logs at a single-band mill in the south-ern part of the Shasta National Forest, and the second for 2,490 logs

The log scale is commonly made by the Spalding rule, whichis somewhat similar to the decimal C rule used on National Forest timber sales. Overrun is greater in smallor very large logs; less with saws of heavy kerf, and greater when thick planks or timbers are sawed. Bui. 440, U. S. Dept. of Agriculture. Plate III,.
