[Frederic Shonnard & W.W. Spooner (1900)] Pouudridge, Somers, and York-town. Pouudridge, not entered by any railway line, actually lost some 300 people in the ten years. Amongst the significant local results thus brought to pass, the most interesting and important, whether considered in its original from 1842 to 1900 579 aspects or ill relation to its later developments, was unquestionably the foundation of the Village — now the prosperous and handsome City — of Mount Vernon. Unlike any other considerable community of Westchester County, Mount Vernon owes its very existence to the railroad. Yonkers, Tarrytown, Sing Sing, Peekskill. New Kochelle, Mamaroneck, Rye, and Port Chester, with White Plains, Bedford, and various other villages scattered through the central and northern parts of the county, existed before the period of rail-ways, and doubtless would have enjoyed respectable growth if no railway had ever been built. Rut Mount Vernon had no such prior existence. In 1850 there was not even an elementary settlement on the site of the present city. Its very name belongs as strictly to the latter half of the nineteenth century as does the name of Irvington. Larchmont, or any other hamlet exclusively conceived and erected, within the memory of men still living, on the foundations of extem-porized enterprise.
