Show Building lloiiara of Paper. The utilization of paper in tba arts of industry and construction presents a notable example in the recent erection erec-tion of a new Hamburg hotel, in northern north-ern Germany, the structure being built entire of paper boards compressed to the hardness of ooa. One advantage of special importance attributed to this novel description of building material ma-terial is the circumstances tha by being impregnated with certain chemical chem-ical solutions, it cau be made absolutely abso-lutely tire proof; the same process of treatment also secures it against the attacks of destructive insects, and might thus specially recommend it for use in certain fiver valleys in the tropics, trop-ics, wood-eating ants having been known to demolish large frame buildings build-ings in less than a month. For some time past a firm at Dresden has successfully suc-cessfully engaged in the manufacture of tool handles and shafts from compressed com-pressed paper chemically prepared, the articles being not only very hard and firm, but possessing the quality of being non-conductors of heat. Another An-other German firm is making pulleys of pasteboards pressed by hydraulic power, having an iron core and strong casing, and are supposed to take up less room, generate less friction, and are water proof. |
