THE CATSKILL AQUEDUCT LEADING INTO HILL VIEW RESERVOIR
square miles and a maximum depth of 190 feet, the capacity of the Ashokan is estimated at 130,000,000,000 gallons, and its cost, exclusive of the real estate involved, will be in the neighborhood of $14,000,000.
The Ashokan dam across the Esopus gorge will be nearly a mile in length and is 240 feet in height. Its width of 24 feet at the top will permit a road to be built across. Work was begun on this dam in 1907, and some idea of its size may be gained from the statement that it will require eight times the material used in the construction of Cheops, the largest pyramid in the world.
From the Ashokan reservoir extends the main aqueduct, known as the Catskill, which will convey the water into New York. When " aqueduct" is mentioned, one instinctively associates the creations of the Romans, who in 97 A.D. had no less than nine, with an aggregate length of 263 miles. But the contents of all
those aqueducts would occupy less than one-fifth of the space within the Catskill. To appreciate its enormity, one must visit a point where hundreds of men and horses, massive steam shovels and rattling stonecrushers and concrete mixers are gradually molding this great concrete tube, 17 feet in height and 17 1-2 feet in width.
This type of construction, known as the cut-and-cover, and forming 55 miles of the aqueduct, is but one of the four distinct types. Where hills and mountains cross the line, and it would be impracticable to circumvent them, tunnels at the natural elevation of the aqueduct are driven thru them. There are 24 of these grade tunnels, aggregating 14 miles. They, like the cut-and-cover, are horseshoe shape, 17 feet high by 13 feet 4 inches wide and lined with concrete. Where deep and broad valleys must be crossed and there is suitable rock beneath them, circular tunnels are
