Show iMAKE EXPERIMENTS ON PAPER MAKING I The Forest Products Laboratory at Madison, Wis . which Is maintained by tho departnv-nt of agriculture to carry car-ry out experimental work with wood, ' Is now conducting experiments to de- j termlne the practicability of manufac-Iturlng manufac-Iturlng paper from various woods i grown in Western forests particularly j Kngleinan spruce. Lodgepole pine and White fir, according to a statement j made by F. S. Baker, forest examiner in charge of public relations of the local forest service. Although no process has been dls- 1 covered by which such paper 'can be 1 made on a commercial basis, on account ac-count of the excess of pith in the wood, the laboratory has manufai - , tured quantities of paper, which )wtv-,been )wtv-,been used for bookwork. Mr. Baker has already received leaflets carrying printed matter on paper manufactured manufactur-ed from spruce and pine I Another process which Is nearly l past the experimental stai" is a ni'-m-od of de-inking newspaper, or recovering recov-ering papt r that has b-en used. The process consists of disintegration of the used paper by means of lye, followed fol-lowed by a treatment with bentonlti i peculiar kind of clay, found in Wyoming, Wyo-ming, which absorbs the clay by some antcal process, not yet clearly understood. un-derstood. I If such a process can be perfected. land put to use In rltl.s where there lis a large waste of newspapers and paper that has been through the press there will be a saving of 35 to 40 per cent in the amount of wood consum- cd each year in the manufacture of .paper. Mr Baker said. |
