=The Catskill Water Supply.=--The cost of this great undertaking is estimated at $162,000,000. Four creeks: The Esopus, Rondout, Schoharie and Catskill will constitute the main source of supply. The total area of the entire watershed is over nine hundred square miles, and the supply will exceed 800,000,000 gallons daily. The work projected will bring to the city 500,000,000 gallons per day. The Ashoken Reservoir, 12 miles long and two miles wide, will hold 120,000,000,000 gallons. The Catskill Aqueduct supply from Ashoken Reservoir will deliver the water without pumping to Hill View Reservoir in Yonkers high enough for gravity distribution. It will take from ten to fifteen years to complete the work, which is begun none too early, as the population of Greater New York will be over 5,000,000 in 1915, and its water consumption 1,000,000,000 gallons. In 1930 the population will be 7,000,000 and will call for a consumption of 100,000,000,000 gallons daily. We are indeed "ancients of the earth and in the morning of our times." From the far limits of the gathering grounds some of the water will flow 130 miles to reach the city hall, and 20 miles further to the southern extremity of Staten Island. * * * The majestic Hudson is on my left, The Catskills rise in my dream; The cataracts leap from the mountain cleft And the brooks in the sunlight gleam. _Minot F. Savage._ * * * Between Old Cro' Nest and Cold Spring the water will be syphoned under the Hudson through a concrete tube six hundred feet below the surface of the river. The Croton Water Works, at a cost of about $14,000,000, completed in 1842, were regarded the greatest undertaking since the Roman Aqueduct. Many improvements to meet increased demand have been made since that time. Fifty years from now it is quite possible that the Catskill System will seem like the Croton of to-day, as a small matter, and our next step will be "An Adirondack System," making the successive steps of our water supply the Croton, the Catskills and the Adirondacks. It is fortunate that our city destined to be the world's emporium, has everything at hand needed for comfort and safety. John Bigelow, the literary and political link of the century, born at Malden-on-the-Hudson, in 1817, was present at the inauguration of the work at Cold Spring, June, 1907. It was the writer's privilege to meet him often on the Hudson River steamers in the decade of 1870, and to receive from him many graphic descriptions of the early life and customs of the Hudson. What memories must have thronged upon him as he contrasted the life of three generations!
