This structure continued in use until about 1855, when it was replaced by the (old) Third Avenue Bridge. Previously to the construction of Coles's Bridge there were two bridges connecting Manhattan Island with the main land, both being across Spuyten Duyvil Creek -- the King's Bridge, erected in 1G94 by Frederick Philipse, who, with his successors, collected tolls from all using it, and the Farmers' or Dyckman's Bridge, built some years before the Revolution by public subscription. No tolls were levied on the Farmers' Bridge, and hence it was popularly known as the " Free Bridge." It will thus be seen that as early as the middle of the second decado of the nineteenth century there were four bridges communicating with our county from Manhattan Island -- one at the village of Kingsbridge, the second just below, the third at the termination of the present Seventh Avenue, and the fourth where Third Avenue now crosses. The incorporation of the village of Peekskill was authorized by an act passed April 17, 1816. But no stops were taken at that time, or indeed until eleven years later, to carry the provisions of the measure into effect. The loss of population by the county during the War of 1812 was speedily recovered. In 1820 the census returns showed a total population of 32,038-- a gain of 2,300 over that of 1810. Mount Pleasant, with its village of Sing Sing, still led, having 3,684 inhabitants; Cortlandt was second, with 3,121; Bedford third, with 2,432; Westchester fourth, with 2.10)2; and Greenburgh fifth, with 2,001. The population of Yonkers was 1,580, being exceeded by that of Yorktown and Seniors, in addition to the towns above named. In the year 1824 this county was the scene of enthusiastic receptions to the immortal Lafayette on his route from New York to Boston.
