Marine Engines for Laud Use.

An interesting departure in engineering is the introduction of marine engines for land aervioe. One of the great electric illuminating companies, it appears, has adopted them in its work, and concerning their economy in respect to space/ and power it is reported, says the Age of Steel, that the land engine takes up some ten times ns muci> room as a marine /engine, and the marine quadruple expansion engine has ten times the heating surface of the land. Further, the new quadruplex twocrank expansion engine is twice as powerful as the triple expansion three-crank engine, occupies also 30 per cent, lessroom and oarries regularly 210 pounds of steam. The land engine carries only 80 or 90 pounds of steam, and gets one horsepower out of from four to ten pounds of anthracrite coal, while the quadruple expansion marine engine develops one horse power out of one and a quarter pounds of Welsh coal—that is, according to these data, the land engine requires from two to four times as much coal as the marine engine to produce the same power. There are in this a- nntiy hens to the estimated number of 600,000,000.
