New York, Boston, and Philadelphia established waterworks about 1800; and so, likewise, did several smaller New England and New Jersey towns. Baltimore came into line by 1807. Only in Philadelphia was the water system a public one, though its example would eventually be followed in nearly all cities.—R. H. Shryock, Medicine and Society in America, 1660-1860, N. Y. U. Press, 1960, pages 102-103.
