[Frederic Shonnard & W.W. Spooner (1900)] This supply can be aug-mented by constructing reservoirs, and we have seen... that one reservoir could be constructed which would supply more than 7,000,000 of gallons per day within a few miles of Pine's Bridge. But if it were necessary, more than 7,000 acres could be ponded, and the water raised from six to sixteen feet; and also other supplies could be obtained, as I have before stated, in alluding to the Sharon Canal route and the East Branch of the Croton River/' He favored the conveying of the water to New York in an open canal, and calculated that the total cost of the work, including the means of distributing the water through the city, would not exceed *2, 500,000. It appears, however, that the employment of Colonel Clinton by the common council to reconnoiter the Croton was only a conces-sion to the advanced element of the population that demanded the most complete investigation of water supply conditions in West-chester County before definite steps should be taken. Simultaneously with his exploration of the Croton route, two other engineers were sent to make a final inquiry as to the Bronx and its related sources of supply; and their report indicates that they were relied on by the city officials to bring forward conclusive demonstration of the suffi-ciency of these sources.
