Water Gages and Glasses One of the most perplexing problems which has presenteditself while operating the modern locomotive is that of secur-ing a correct indication of the height of water over thecrnwn-sheet under all conditions of serce. In the last annual report was included the results of testsmade to determine the action of water in tlie boiler on thewater-indicating appliances with respect to their correct reg-istration. These tests established that gage cocks screweddirectly in the boiler do not correctly indicate the general. Leaking BaOly But Reported Ready for SerClosed ice: Cylinder Cocks water level wiiile steam is rapidly escaping from the boiler,and in order to secure a fjroper appliance it was recom-mended that a water column to which three gage cocks andone water were attached Ix; applied. As far as the Inireau ha~ Ijeen able to determine, prac-tically all new Iricomotives constructed since that report wasrendered have had water columns applied. On old locomo-tives the application has not progressed rapidly, probablydue to the difficulty in obtaining necessary for such appliances, however, is practically un-questioned, and some roads are proceeding with the a])plica-tion in a verj satisfactory way. It is hoped that in the nearfuture this important appliance will be ajjplied on all loco-motives, so that enginemen may have accurate knowledgeof the general water level in the toiler under all conditionsof service.
