A very good instance of the initial strategy is discovered at the worksof the International Acheson Graphite Company, where 750-kw. resistance furnaces are utilized.

I will pass around for observationseveral cards showing the effect of insufficient lubrication. Youwill notice that area representing the work done, of the head end,is very much reduced. By increasing the supply of oil from fiveto fifteen drops per minute, the diagrams again become normal.By means of the indicator we were able to detect a springing inthe valve gear, and this trouble was overcome by substituting anintermediate blade or motion bar of I Beam section for one of arectangular and smaller section. i.5~s: 10 WHEEL PASS.
