It seemsto be rather far-fetched. Be thatas it may, there is demand for that styleof cylinder, and the locomotive buildershave to meet it. It greatly increases thedanger of failure in casting cylinders. A. S. Valve-Stem Guide. The device shown in our engraving,was designed on the Old Colony Railroadfor the purpose of relieving valve-stempacking of the weight of the parts usuallysupported by the same, and thus insurelonger life to the packing by saving undue U \iH--~ v. —f--T*f ;,£ ■- L — ♦XT _t6M _ Zoeoauxuw £njlnrtrtng /fr1—f cranes. Above every tool where work isdone that one man cannot lift easily, thereis an air lift, most of them being madefrom brass tubing. While loungingaround the machine shop,I got watching a man boring the brassesof solid-ended rods, and I was struck withthe extraordinary care he exercised inmeasuring for the center. When talkingto Mr. White, the assistant superintendent,about the great care with which the workwas done, he said that they required ab-solute accuracy in the boring of theseholes. To show how close the work wasdone, he took two sets of side rods for aten-wheeler, with the front and back pins15 feet centers; then the workman tookplugs 1-64 inch larger than the crank pins,and put one into each of the holes, andthey went down through the brasses ofboth sets of rods. The fit was just suffi-cient to make the plug,
