WARING, George E, sanitarian, born in Pound-ridge, New York, 4 July, 1833. He was educated at College Hill, Poughkeepsie, and then studied agriculture with James J. Mapes. During the winter of 1854 he made an agricultural lecture tour through Maine and Vermont, and in 1855 he took charge of Horace Greeley's farm at Chappaqua, New York, which he conducted on shares for two years. In August, 1857, he was appointed agricultural and drainage engineer of Central park, New York city, where he remained for four years, during which time, among other duties, he prepared the soil of the Mall and set out the four rows of elms upon it. He was appointed in May, 1861, after the opening of the civil war, major of the Garibaldi guard, with which he served three months. In August, 1861, he was made major of cavalry by General John C. Fremont and went to St. Louis to join him. There he raised six companies of cavalry under the name of the Fremont hussars, which were afterward consolidated with the Benton hussars to form the 4th Missouri cavalry, of which he was commissioned colonel in January, 1862. In this capacity he served throughout the war, chiefly in the southwest. He settled in Newport, Rhode Island, in 1867, where he became the manager of Ogden farm. Colonel Waring then devoted himself to agriculture and cattle-breeding and to engineering, until the latter occupation required his full attention in 1877. Since that date he has been in active practice as an engineer of drainage. He was appointed in June, 1879, expert and special agent of the 10th census of the United States, with charge of the social statistics of cities, and he has been a member of the National board of health since 1882. After the yellow-fever epidemic in Memphis in 1878 he devised the system of sewerage that was accepted for that city and since that time has been generally adopted, he has invented numerous sanitary improvements chiefly in connection with the drainage of houses and towns. He has been connected with various journals and edited the " Herd-Books of the American Jersey Cattle Club" in 1868-'81, of which organization he was the founder. His other works are "Elements of Agriculture" (New York, 1854) ; "Draining for Profit and Draining for Health" (1867); " Handy Book of Husbandry" (1870, now called "Book of the Farm") ; "A Farmer's Vacation" (Boston, 1875); "Whip and Spur" (1875) ; "Sanitary Drainage of Houses and Farms" (1876) ; "The Bride of the Rhine" (1877); " Village Improvements and Farm Villages" (1877) ; " Sanitary Condition of City and Country Dwelling-Houses" (187'7); "Tyrol and the Skirt of the Alps" (New York, 1879); "How to Drain a House" (1885) ; and "Sewerage and Land Drainage" (1888).
