Not illustrated. 1896 edition. Excerpt: ...Mountains, dependent upon pumping from streams, and upon gravity supplies. The most noticeable feature is the very large storage of such cities as New York, Boston and Newark, N. J., all of which are dependent upon streams upon which it has been necessary to create storage. The table speaks for itself, and any further reference to it is unnecessary. 1869-1890 I h (." _: i! 1 2-Aw-rn D. tion. 1 3-'l'olu' Pun: Stalioua on, E I----v-3 1. l v lil. _.., 'Also Flo. 1.--MINIMUM FLow or THE SCHUYLKILL RIVER.

Whether this should be obtained by means of impounding dams within the drainage area of the stream, or by additional distributing reservoirs to be filled by pumping when the river is at its normal stage, it is not within the scope of this paper to discuss.
