Wherever the maintenance is not ofthe highest order, the standard runningpressures should be below 180 the water which must be usedin boilers contains foaming or scale-making admixtures, the best results arelikely to be secured by fixing the pressurebelow the limit of 180 lbs. A simple locomotive using saturatedsteam will render good and efficient ser-vice when running pressure is as low as160 lbs.; under most favorable conditionsno argument is to be found in the eco-nomical performance of a machine whichcan justify the use of
