The mechanical de-partment of the Great Eastern Railwayof England have been keeping a close rec-ord of the wear of tires of six coupledsuburban engines, and hard tires wereshown to be much superior to soft with a tensile strength of 40 tons gavea service of only 2,197 miles to 1-32 inchof wear, and tires with a tensile strengthof 48 tons ran miles per 1-32 inchwear. This was considered as being con-clusive evidence that hard tires were moreeconomical than soft ones. We do notfeel entirely certain the Great East-. FIKST TEN-WHEELERS IN GREAT This engine is one of the fifteen recentlydesigned and put into service by Mr. , locomotive superintendent of theHighland Railway, at Inverness. Theywere built by Sharp, Stewart & Co., atGlasgow. These are claimed to be the most power-ful engines in Great Britain. They havecylinders 20x26 inches with S-foot drivers,1,520 square feet of heating surface. ^ ^ ^ Running Engines Without Cylinder Oil. At the annual convention of the .Xnieri-can Society of Mechanical Engineers,held in New York City last month, an ex-perienced engineer made the statementthat engines could get along without cyl-inder oil. He said that some of the bigsteamships use no oil in the cylinders oftheir engines. The steam acts as a lubri-cant, and, when nothing else is used, therubbing surfaces become glass-like insmoothness and extremely hard. Thisis, no doubt, a fact; but we should n
