He gives briefly, butquite clearly in most cases, the rules ofarithmetic and algebra that are needed bythe mechanic. This includes algebra,logarithms, geometry, trigonometry, men-suration, etc., all of which are useful andnecessary at times. Strength of materialsand laws of mechanics are treated, andcranes, derricks, belts, shafting, etc., allreceive attention. It is a book which anymechanic will find useful. 248 LOCOMOTIVE ENGINEERING June, I goo. Engines for Sweden. The Richmond Locomotive Works havejust completed and shipped to the YstadEslof Railway, one of the private roadsof Svi^eden, three i6;s4 x 24-inch ten-wrheeled locomotives with six-wheeled ten-ders. The engines were designed throughout. HEAD ON. by the Richmond Locomotive Worlds, and,with the exception of the smoke-box door,buffers, snow plow, English vacuum brake,copper firebox and btays and a few otherminor details, are in accordance withAmerican practice, which was the expresswish of the railway company. Three photographic views of one of the Mr. Dan Olson, mechanical engineer ofthe road, inspected the engines duringtheir construction. The general dimen-sions of the engines are as follows: Gage—4 feet SVz inches. Fuel—Coal. Weight on drivers—72,600 pounds. Weight in working order—99,100pounds. Wheel-base, driving—12 feet i inch. Wheel-base, total engine and tender—43 feet 4 inches. Total length of engine and tender—53feet 2 : Diameter—165^ in hes. Piston stroke—24 inches. Piston packing—U. S. Valves: Style—Richardson balanced. Greatest travel—SA inches. Lap—Outside, %
