GEOMETRICAL DEFINITIONS AND TECHNICALITIES GEOMETRICAL PROBLEMS GEOMETRICAL PROJECTION DBA WING OF MACHINERY Within the last few years, both here and abroad, a number of works have been published on " Practical Drawing," but no one work has illus- trated all departments of the sitbject.

William Worthen was born on March 14, 1819, in Amesbury, Massachusetts, the son of Ezra Worthen and Mary Currier. His father was one of the projectors of the city of Lowell, Massachussets, and was made the first superintendent of the Merrimack Mills there in 1822.
Worthen was prepared for college in Boston, and graduated at Harvard in 1838.
He began his professional career as an assistant in the office of the younger Loammi Baldwin upon water-supply and hydraulic work in Lowell and Boston, then in similar capacity was associated with James B. Francis, another well-known engineer. In 1840-1842, he was engaged under George W. Whistler upon the Albany & West Stockbridge Railroad, with seven miles of road in his charge. Returning to Lowell with Francis, he designed and built many dams and mills and carried on other hydraulic work in eastern Massachusetts and southern New Hampshire. After a visit to Europe, he settled in New York in 1849, engaging in building and mill construction. He also built the dam across the Mohawk River at Cohoes, New York, and the floating docks for the Jersey City depots of the Erie Railway. He was widely known as an expert upon pumping machinery, and was called upon both to design and to test such machinery in New York, Cincinnati, and St. Louis. He also selected pumping engines for Boston and tested large pumping units at Brooklyn, Lawrence, Philadelphia, Milwaukee, and other cities. He had much practice in the measurement of flow of water in canals, reporting upon this subject for Paterson, Trenton, Passaic, Indianapolis, and other places. In addition to his consulting practice, he served for a time as engineer of the New York & New Haven Railroad, of which he was made vice-president in 1854. From 1866 to 1869 he was sanitary engineer to the New York Metropolitan Board of Health, and served on a number of engineering boards in connection with various municipal projects. In Brooklyn he reported upon an extensive addition to the sewer system. In 1890-1891 he was chief engineer of the Chicago Main Drainage Canal. Worthen was the editor of Appleton's Cyclopedia of Drawing (1857, many later editions), and the author of First Lessons in Mechanics (1862) and Rudimentary Drawing, for the use of Schools (1864), as well as a number of professional papers read before the American Society of Civil Engineers and published in its Transactions.
William Ezra Worthen was paralyzed by a stroke in December, 1896, and died on April 2, 1897, in New York City.
