Fig. i shows thepacking nut used on the lower fitting for compressing the packingaround the glass so that it will be water tight, and you will notethat the orifice is completely filled up with rubber, except for asmall hole (less than 1/16 inch in diameter), in the middle. It isalso to be noted that at the time of the accident, sediment whichhad settled in the bottom of the glass had closed off the openingto a still greater steam Space \ Water ipac rurnac©Opening Ash pitOpening Water Level (-This fitting stoppedup with rubber caused a false water level registration. The water gage glass ofa boiler is one of its mostessential fittings.

Figure2 shows the function a water gage glass is expected to per-form. The attendant should check the accuracy of the waterlevel shown in the glass from time to time by opening valveA, through which steam should escape. After closing it heshould then open valve B, from which water should flow. Then thedrip cock, C, should be opened to see that it is clear and is not only necessary for the attendant to do this, but all con-cerned with having a well heated building should frequently I
