     Frederick Law Olmsted (1822-1903), a Connecticut farm boy, saw his first public park in Liverpool,

England, as he accompanied his brother on a walking tour. He was impressed by the park's winding paths,

open fields, lakes and bridges. Perhaps the most wonderful things of all was that the park was open to

everyone.

     A moment beginning in 1840 to set aside park land on New York City's Manhattan Island had a successful

result in 1856 with the purchase of 840 acres of rocky and swampy (沼泽) land, bought with about $5

million in state funds. Olmsted's chance meeting with a project organizer led to his applying for the job of

park manager. In 1857 Olmsted was appointed manager of the proposed park, and the clearing of the site

began.

     Calvert Vaux, a British architect, asked Olmsted to collaborate with him on a park design, and Olmsted

agreed. Vaux saw the park as a work of art, while Olmsted saw the park as a place for people to escape the

noise of the city. Together they invented a plan that would give the persons and animals living in the city a

quiet, green park and would also preserve and increase the good qualities of the natural features of the land.

The commissioners voted in favor of Vaux and Olmsted's plan, and in 1858, the two became the official

designers of New York City's Central Park.

     It took millions of cartloads of topsoil to build Central park's gentle slopes, shady glens, and steep, rocky

ravines. Five million trees were planted, a watersupply system was laid, and bridges, arches, roads and paths

were constructed. The park officially opened in 1876, and today, well over a century later, people still escape

the noise of the city in Olmsted and Vaux's great work of art.
