Iron is now used in architecture, ships, and rigging. Wire ropes are era- 

 ployed in many mines. At equal strengths, a wire rope is lighter by one-third 

 than a hemp rope, and by two-thirds than a chain, an important fact. Then we 

 have metallic life-boats, pontoons, and army-wagons; the boats now made, it is 

 said, cannot be broken or overset, let them be used ever so roughly, and the pon- 

 toons are models of lightness. Wo are to have, they say, railroads to California, 

 and the railway to India, by the Euphrates valley, while that from Honduras to 

 the Pacific, 161 miles, seems a fixed fact, so that the demand for iron will be un- 

 limited.* 



Glass will be the next thing" generally introduced, and for new purposes. We 

 have seen a glass mantle-piece, and glass picture and looking-glass frames; there 

 is in Philadelphia a street pavement of glass, cast in octagons, which has been 

 laid down for many years, and is now uninjured; why not glass tables, &c., as 

 well as crystal palaces. Moulding glass is yet in its infancy.
