n taken with theboiler head fittings. There are two gaugeglasses with automatic cut ofif and pro-tectors of heavy glass. Two double deSimons sight-feed lubricators oil the pis-ton and valve rods, cylinders and valves properly in many places. The builder ofthis type of engine had to go deep intomany ways of thinking to get it to itspresent high standard of efficiency. Ofcourse, with the slide valve engine, as allparts increased in size, the steam pres-sure would also increase. Under thesecircumstances, the only thing to do was,if possible, apply valves which wouldbe almost a perfect balance; it was foundthat the piston valve would meet the re-quirements. It was installed, and is giv-ing entire satisfaction, provided, of course,that it is handled in the right way.With the inside admission pistonvalve it was necessary to arrange forthe relief of compression in the cylinders,and introduce a means of safety for theprotection of cylinder heads from beingknocked out by water getting into the

Heavy Locomotive on the SwedishState Railways. The engine illustrated is a Mellin two-cylinder compound, the reducing and in-tercepting valves are contained in a boxover the front foot plate ahead of the low-pressure cylinder on the right side of theengine. Hensinger Von Waldeggs valvegear is employed, and the cut off is regu-lated by screw-reversing gear. The engine and tender are equippedwith the New York air brake, having dif-ferent braking power on loaded and emptytrains. The duplex air pump may beseen on the running board on the rightside. The cab is made of wood, covered on using the Malmros oiling device. Theboiler is fed by two Gresham and CravenNo. 10 injectors. Some of the principal dimensions are asfollows: Cylinders, 21^ and 32x25^ ins;diameter of driving wheels, 51 j\ ins.;wheel base, engine and tender, 45 ft. ij^i
