Editing Hartsdale, New York (section)

===19th Century===
The area remained largely agrarian until 1865, when Eleazar Hart deeded land for the development of the [[New York and Harlem Railroad]] line into Manhattan, setting the stage for Hartsdale's change into a more cosmopolitan commuter village. Between 1880 and 1940, large tracts of farmland and estates were subdivided and converted into private houses and apartments at a furious pace.<ref>{{Cite book|title=Land and Water Resources of New England/ New York|last=Brudage|first=Percival|publisher=U.S. Government Printing Office|year=1957|location=Washington D.C.}}</ref>
