NOVEL FUEL SCHEME

Greeter heat is obtained from coaldust than from lumps of coal, .and a very novel scheme has l>een evolved to supply New York with 7,000,000 tons of this fuel yearly. It is suggested that nvo 14in. pipe lines be constructed between the coaling district of Swanton, in Pennsylvania, and New York City, and that coal-dust and water be pumped through them. This at first does not sound practicable, but tests have shown that a mixture of equal weights of coal and water can be pumped through such pipes, while even after the mixture has been allowed to stand for 24 hours pumping has been. successfully resumed, despite the fact that the coal-dust had settled down in the water. After being separated from all impurities the con! would be crushed and introduced into the pipe linos, along which it would lie carried by the water pumped at high pressure. Pumping stations would b« established lit intervals. At the New York end of the lines there would be huge separators, placed at a sharp slojie, which would allow tho water to drop through to tanks below while the crushed coal continued down a. shoot into waiting trucks.
