The water in the territory where thesetests were made is very light and foamsbadly when compound is not used. It isimpossible to outline this flow of wateraccurately as it changes with the operat-ing conditions and the condition of thewater in the boiler, but it is believed thatthis serves to illustrate the general con-dition which prevails to a greater or lessextent in all locomotive boilers, espe-cially those equipped with brick arch andarch tubes, while the locomotive is work-ing heavy.
