Show FORESTERS 00 OUT TO CRUISE IN 1 1110 FOREST Hubert C. Williams, forest examiner, left Ogden yesterday for Emmett, Idaho, where he will have charge of a field of the north fork of the Pay-1 Pay-1 ette river, in the Payette and Idaho I national forests. The party will be ; composed of William A. Smith, who ' spent the winter in Ogden a' year ; ago, and who is now on the Pavette forest, Irwin W. Cook, professor of I forestry in the University of Idaho I William F. Tribe, and two additional I men. The north fork of the Pavette has I its source in tin Payette lakes, and it is up the valley of this stream that the Oregon Short Line is building north from Emmett, so thul trains will probably be running into McCall I during the coming summer. With railroad transportation facilities fa-cilities directly to Emmett, Boise. Payette, and Nampa. a demand Is anticipated an-ticipated for the splendid yellow pine timber along this river, so that a close estimate of the quantity and I location or the timber, and of the natural divisions by which It can be I appraised and sold in logging units are essential Maps will be prepared j which will show the lay of the coun- try and, by colors, the character of " the land and the kinds of timber. The timber will be estimated by "cruising " the tract being taken up by tit acre compartments. Tn the heavy timber a "10 per cent estimate" will ie obtained by running strips two chains (8 rods) wide across each forty, or bv two strips one chain wide across each forty By measuring with calipers the diameters of all trees over 12 Inches in diameter at breast-heiphr breast-heiphr on such a strip, computing for the trees m asured the merchantable cot.tent in board feet of lumber, and multiplying the total of board feet In the strin hv 1 fl thp annrrTiniate stand or" the forty acres is ascertained. The number who work together in cruising a strip is varied according to the kind end size of timber and the nature of the estimate desired, smaller and consequently more trees being included In an estimate of material for a paper pulp mill than of timber better suited for saw logs. When two men work together, one man runs a straight course with the aid of a coin-pass, coin-pass, taking notes for the map and preparing a sketch map as he proceeds. pro-ceeds. The distance traveled Is determined de-termined by pacing, and In this forest-ors forest-ors become expert by practice. The double-pace count is made on one foot, usually 1,000 double paces of a little over 5 feet, I-' inches each, to the mile, so that at the end of 250 double paces he has reached the limits of the 10-acre compartment. The other man estimates the timber and takes note on its condition The timber of the north fork of the Payette tract consists raainlv of pine but the tract contains a great deal o. whltefir and other species suitable for pulp, which would be utilized to 6 inches diameter. |
