Therefore, a cost of five cents per acre fora 10 per cent estimate is representative of average conditions. Lodgepole pine is not quoted separately in the census figuresbecause it is only of importance locally, but the stumpage price forany particular tract can be figured by deducting the cost of log-ging and milhng from the sale value of the finished product. Onaccount of its small size — very few trees attain a diameter breast-high of more than 14 inches — relatively little lodgepole pine issawn. Most of it is used in the round as mining timbers, fencingor hewn railroad ties. Moreover, the little that does go thru thesawmill makes narrow, lo
