Excerpt from Observations on the Flow of Rivers in the Vicinity of New York City In most parts of the country the public water supply of the cities and towns must be derived from the rivers. Large sums are expended every year in conducting water fromthe streams to the centers of population. Before this money is expended it Is of the greatest importance to know that there is sufficient water at all times for the use of the town. Too often have great hydraulic works been built before proper investigation has been made of the flow of a stream, and great financial loss has resulted.
