The enterprise has been so far a great engineering success, and the oil
delivery is stated on good authority to be within 2 per cent. of the
theoretical capacity of the pipes. From a commercial standpoint, the
ultimate future of the undertaking will be determined by the lasting
qualities of wrought iron pipe buried in the ground and subjected to

THE FUEL OF THE FUTURE.
By GEORGE WARDMAN.
The practical application of natural gas, as an article of fuel, to the
purpose of manufacturing glass, iron, and steel, promises to work a
revolution in the industrial interests of America--promises to work a
revolution; for notwithstanding the fact that, in many of the largest
iron, steel, and glass factories in Pittsburg and its vicinity, natural
gas has already been substituted for coal, the managers of some such
works are shy of the new fuel, mainly for two reasons: 1.
