In the first instance, in order to appease the bugaboo of water famine which periodically torments New Yorkers, this is to be connected with the New Croton system. Later on, however, the yields of the two groups of watersheds will be carried southward by, to all intents and pur- poses, quite independent means. After passing beneath the New Croton Reservoir, the Catskill Aqueduct will be con- tinued to Kensico, where another great reser- voir is to be constructed, capable of storing 40,000,000,000 gallons, of which about half will be always available. This basin will be formed by a masonry dam, 1,200 feet long and having a maximum height of 250 feet, built across the valley of the Bronx. The dam will contain about 1,000,000 cubic yards of masonry, and be 28 feet wide at the crest and 230 feet wide at the bottom. Four miles south, at Scarsdale, a large filter- ing plant is projected, and thence the aqueduct will be continued for a further distance of six miles to Hill View, just outside the city bound- ary. Here is being built a distribution reser- voir, with a capacity of about 800,000,000 gallons—an ample insurance, it would appear, against possible difficulties caused by any sudden interruption of supply by failure of the ninety-two miles of aqueduct to the north. By the construction below the East River of a huge tunnel of 200,000,000 gallons daily capa- city, of a storage and distribution reservoir in Brooklyn, and of a great pipe line carried CUT-AND-COVER SECTION OF THE CATSKILL AQUEDUCT, SHOWING CONCRETING OVER STEEL MOULDS.
