The grade was required to correspond with the regulation of the streets, which had required much deep cutting and some high embankment. About four miles of the road are now in use. upon which pleasure cars are constantly run. for the accommodation of those who desire to get out of the city for a short time. When completed, there will be a tunnel of some length through a rock, at Yorkville, after which there will be a gradual descent to Harlsem River. The work, thus far. has been very expensive, and will cost, when completed, at least its whole capital, and probably more. At present horse-power is used. A locomotive engine was provided and used for a short time but the boiler burst mid the engine was laid aside."

HISTORY

WESTCHESTER

COUNTY

from the south side of the Harlem River Bridge to Williams's Bridge was $38,475 per mile, and from Williams's Bridge to White Plains $11,277 per mile. It is noteworthy that the tirst telegraph line through Westchester County was erected (1846) under the superintendence of Ezra Cornell (subsequently the founder of Cornell University), a descendant of Thomas Cornell, of Cornell's Neck. Ezra Cornell was, moreover, a native of this county, having been born at Westchester Landing. He was the father of Governor Alonzo B. Cornell. The beginning of the gigantic Croton Aqueduct enterprise dates from about the same time as the chartering of the first Westchester County railroad. On November 10, 1832, the joint committee on tire and water of the New York City common council engaged Colonel De Witt Clinton, a competent engineer, to examine the various sources and routes of water supply which had been suggested up to that time, and to make a careful report on the subject. Colonel Clinton recommended the Croton watershed as the source of supply, and demonstrated by unanswerable facts that no other source adequate to the ultimate needs of the city was available.
