. American engineer and railroad journal . ine engines to the serviceof railroads for pumping and raising coal received comment inour February Issue, and an appreciation of tlie advantagesto be gained by their use will undoubtedly be followed by al-most universal appication of these engines for such service.

Iiorse power,the one shown being the 4 horse power size. The parts of theengine, particularly the bearing surfaces, are large, being de-signed with reference to long wear. Cheapness of first cost isnot sought after at the expense of good, durable bearings are of phosphor bronze, and all parts are madeon the interchangeable plan, which would not be possible withbabbitted bearings. The crank shiifts and connecting rodsaie forged from solid steel billets and the fly wheels, which. The Sumner Gas and Gasoline Engine, are double for all but the 2 horse power engine, are veryheavy. The best grade of iron is used in the castings, the baseand cylinders being of very hard iron to Insure long life. One of the features for which much is claimed by the build-ers is the electric igniter, which makes use of a magneto ma-chine, employed only In the Sumner engine. These are usedwith the expectation that they will last as long as the engineand effect a great saving over the batteries that are generallyemployed for obtaining the sparks for ignition. The magnetois advocated because of avoiding the cost of renewing and re-placing batteries and tube igniters. It is clear that ignitingdevices that may be depended upon not to fail at critical timesmust be appreciated, and uncertainty in this regard has un-doubtedly exerted an influence in retarding the introductionof internal combustion engines. These builders guarantee theigniting device
