upply hurds, as machine methods have not been adopted thereto any appreciable degree. The Ohio and Indiana region, which atpresent has the greatest annual tomiage, with the prospect of an in-crease, is situated south of the Wisconsin and Michigan wood-pulpproducing region and at a distance from the eastern wood-pulpproducmg regions; therefore, it is in a favorable position to competem the large Ohio and Indiana markets. Since, as will be shown,the hurd pulp acts far more like soda poplar stock than sulphitestock, competition would be strongest from the eastern miUs; mfact, the hurd stock might very possibly meet with favor as a book-stock furnish m the Michigan and Wisconsin paper mills, which arewithin the sulphite fiber-producmg region. Because of its very closeproximity to paper mills, this latter possibility applies with fargreater force to the Wisconsin hemp region, where a considerableextension of the hemp mdustry is anticipated. 10 BULLETIN 404, U.

As received from Pierceton, Ind., the hurds consisted of a mixture oftangled hemp bast fibers and pieces of broken wood of the hempstalk. (Fig. 3.) No reliable data were secured as to the propor-tion of bast fiber in the total shipment of 4 tons, although twohand separations of small representative samples gave results aver-aging 8 per cent. The chemical character of the material was suchand the quantity was so small that any appreciable variation of theproportion should not affect materially the treating processes finallyadopted, yet its presence in varying proportions undoubtedly would
