These inter-fere with the efficient operaticjn of theboilers, increasing the amoutit of fuelused, shortening the life of sheets andtubes, and causing leaks. At times,also, feed jjipes become stop])ed u])and injectors heavily encrusted. While the territory in which acidvaters are found is not as large as thatoi the scale formers, they present aserious source of danger. The actionof the acid is very rapid and results in. Water Treating Plant at , Pa. 8 Baltimore and Ohio Magazine, August, ig22 grooved and pitted sheets and flues,weakened staybolts and the rapid re-tiring from service of the locomotivesusing them. Waters of the third type are onlymet with occasionally on this roadand their action is about the same asthat of the acid waters. Our principalexperience with them has been atCurtis Bay and on Staten Island,where wells have become contamin-ated with sea water. In addition to the above we some-times have corrosion as a result ofgases in the water. Also some sourcesof supply, which in other respects areof good quality, carry in time of freshets, large quantities of mudwhich place them temporarily in thefirst class. Natural Supply of Good Water Decreasing It is becoming more difficult everyyear to get good natural supplies ofwater, as the removal of the forestsfrom the hills a;nd the drainage of thelowlands leave little water in reserve,while the i
