Logging; the principles and general methods of operation in the United States . ARDING 451 A galvanized gutter is then inserted into each incision, thelower gutter projecting about i^ inches past the upper one sothat it forms a spout to carry off the resin from both gutters. A6-penny zinc nail is then driven on the face opposite the lowergutter and in such position that the gum will drain into a cuphung on it. Wire nails were for-merly used for hanging cups butthey were difficult to pull from apitchy face and laborers oftenleft them in the tree, whichdamaged the saws at the millwhen the timber was sawed in-to lumber. Zinc nails are softenough to be cut by a band sawwithout injury. Cups are hung by crews fol-lowing the gutter placers. Atthe end of the season cups areremoved from the nails andturned upside down by the tree,since they break if water accu-mulates and freezes in them. The placement of cups andgutters is done largely by daylabor. On an Alabama operation the crew for placing Hertycups and gutters was composed of eighteen men whose dutieswere as follows:. Fig. 131. — A Tree equipped with aHerty Cup and Gutters. The firststreaks will be cut at the upper edgeof each face. 2 men cutting streaks4 men cutting faces2 men cutting incisions forgutters I man distributing gutters6 men placing gutters 1 man distributing cups 2 men driving nails and hanging cups This crew averaged about 2500 cups per day, and the averagecost per crop for labor was $100. The second and following seasons only ten men were requiredto hang the same number of cups, because the streak and facecutters and the gutter and can distributors were not needed. 452 LOGGING The cost of installing a crop of this character as estimated bythe inventor ^ is as follows: Cups (10,500 at 15 cents) $131. 25 Gutter stripping (1,886 pounds of galvanized iron, 29 gauge, cut in 2-inch widths) Nails (6-penny wire Dails)^ Freight charges (estimated)^ Labor at tree Cutting and shaping gutters
