Thomas A Edison Iks discovered how to mske "Portland cement ' at an extremely small cost, says a recent New York dispatch to the Chicago llccord-ltcrald This statement, at first thought, seems to ha comparatively im-Imporant im-Imporant Yet IMIson knows the Im roense value of his discovery lie ex pects that his cement will drive out quarried slono and brick as building materials Ho foresee as the result ot his discovery that It will cost very little to build houiea, and that therefore, there-fore, rents will he very low lie alto foresees that these same houses will be as nearly fireproof as concreto and , eleol frames can make them With cement til cheap a house will be "poured ' not bullded And the "pouring" of the houso will occup) but a fow days Tho houso will be hablt-nblo hablt-nblo when tho concrete solidifies Kor several )eara Mr Edison his been working on the recent problem and tho problem ot making cheap and practical prac-tical storage batteries lloth Intentions Inten-tions havo now been perfected Insurance Insur-ance Knglneerlng, which will bo pub llsbed tomorrow will contain an Interview Inter-view of Its editor with Mr IMIson Tho Inventor Bays cement, combined with steel, will bo tho building material mate-rial of tho future, and continues- "My Impression Is that lb" "me wy.tlt come when each contractor will hate standard stand-ard forms ot bouse, twenty or thirty varieties Tho forms will bo made of wood, and a contractor, using one of the standard shapes, will simply go out and 'pour' n house Thcro will probably prob-ably bo hundreds of designs Tho contractors con-tractors will put up their concreto fixer and have their beams and forms ready Thoy will pour the form for the llrst story and so on.
