6318. PAINE (Thomas), Iron bridge.—[further continued] .
Mr. Paine, the author of
“Common Sense”, has invented an iron
bridge, which promises to be cheaper by a great
deal than stone, and to admit of a much greater
arch. He supposes it may be ventured for an
arch of five hundred feet. He has obtained a
patent for it in England, and is now executing
the first experiment with an arch of between
ninety and one hundred feet.—
