We use an anti-foaming treatment to prevent foaming,both with our treated water and in territories where the water isnot treated, which does the work very satisfactorily, eliminatingall of the troubles due to a foaming boiler, reducing the cost offuel and lubrication, and enabling us to handle tonnage that itwould be impossible to handle otherwise. In territories wherethe water is not bad enough to warrant the installation of treat-ing plants, but does give trouble with foaming, w^e find thatanti-foaming preparations have a favorable effect in preventingincrustation as well. It is but just and fair to a water treat-ment that counteracts or prevents foaming, to give it credit for zoopoo J. 1905 I3(X 1907 Solid Line Shows Number of Engine Miles per Fine Leaking Failure and Dotted Line the Number of Such Failures on the Los Angeles Division of the Santa Fe for the Past 7 Years. adding to the life of the firebox and flues, on the theory thatwhen it prevents foaming it keeps the water in a more densecondition, so that it absorbs more readily the heat that is pass-ing through ihem, and by so doing prevents their overheating andconsequent damage. Other conclusions reached by the committee were that treatedwater increases the tendency to foam ; that anti-foaming chem-icals are successful; that treated water does not increase the mile-age between washouts; that the efficiency of the locomotive isincreased by the use of treated water, especially if used in con-nection with an anti-foaming treatinent; that the increased foam-ing of waters treated for scale increases the cost of maintenanceof the locomotive; that blow-off cocks should be freely appliedand used
