The same study gave figures on the overrun of the lumber tally 
over the log scale (Table 8). The mill was an efficient single band 
with standard equipment. The sawing practice was normal for the 
region, except that railroad ties were sawed from many of the top 
logs, which gave too high an overrun for Grade III logs.

VALUES AND GRADES OF LUMBER. 
The value and amount of the higher grades of lumber obtained 
from a species measure its intrinsic commercial worth. 
Sugar pine logs yield a higher percentage of wide, clear, high-grade 
lumber than yellow pine. This material commands a high price for 
special uses in the trades, which accounts for the lumberman’s
