The reading shouldbe made as follows: When the waterraises 1-in., it also lowers 1-in. in opposite*glass. Add these two together making atotal of 2-ins. If water raises 2-ins., it also lowers 2-ins. in correspondingglass, making a total of 4-ins., adding thevariation of both glasses together. The purpose of the vacuum tube is toascertain whether a locomotive is gettingfree circulation of air in ash pan, whichis absolutely necessary to make a goodsteaming and free working engine. Loco-motives will generally tear holes in thefire either in front or back end and per-haps along the sides of the firebox.(ithers will burn an even fire, but will notsteam, indicating that engine burns a dullred fire and that the right temperaturehas not been secured. Oxygen is neces-sary to form perfect combustion andshould be supplied
