Wire glass has become an important industrial produclin the last 20 years. Frank Shuman patented the firslpractical and commercial success in 1892, winning nextyear the premium of the Franklin Institute, glass is very useful in all kinds of skylights, andespecially when required to cover large spaces into whichlight must be admitted, like the long weather-protectedpassenger platforms of railroad stations. It is alsoavailable for windows in exposed locations, as a precau-tion against fire or accident. In the event of fire to. Geo.

Butgas is necessary to the operation of a tank. Improve-ments in glass making methods have all been along theline of substituting gaseous for solid fuel. In window making prior to 1888 the old style furnacesand flattening ovens had been in use for 50 years. Thetank method was then in operation in Belgium, and someyears later this was, through the instrumentality of , introduced here at Jeannette, as alreadystated. In 1890 tank furnaces were considered an ex-periment. In 1905 their value had become so generallyrecognized that the number of them in operation was287, with 2,354 rings, equivalent to 4,708 pots. There which it may be subjected, the iron wire, which is fusibleat a higher temperature than the glass it binds, will holdthe glass together, even after it has
