West Chester is the county town and seat of
  justice of Chester County, Pennsylvania.  The exact location of the borough, or rather
  of the court-house, was ascertained in 1843 by E.W. Beans, then principal of
  the public school in West Chester, and Walter Hibbard, surveyor and
  conveyance.
  It is situated on the
  water-shed or dividing ridge between the Brandywine and Chester Creek, 2 miles
  from the former stream, near one of the sources of the latter, 5 miles s of
  the great Limestone or Chester Valley, 23 miles west of the original city of
  Philadelphia, about 16 miles north of Wilmington, Del and about 456 feet above
  tide.
  On the 28th March, 1799,
  the town of West Chester was erected into a borough by an act of the
  Legislature.  This elevation required burgesses and assistants to manage
  the municipal affairs.  At the census of 1790, West Chester was but
  4 years old - and was only counted as a portion of Goshen Township
  The original plan of the
  village or town proper of West Chester consisted of 4 contiguous squares, with
  2 principal streets crossing in the center, and yet, simple as it was, with
  that utter disregard of symmetry and lack of good taste which
  characterized the projectors of the plan and early buildings, neither of the
  streets crossed at right angles and consequently none of the so-called squares
  was rectangular.  An oblique policy, strongly redolent of barbarism,
  seemed to prevail among the primitive Cestrians, and it's sinister influence
  was long perceptible.  In 1829, several additional streets were opened
  and new squares formed.  People then began to perceive the advantage of
  setting private dwellings back from the street, of having side-yards, and of
  planting ornamental shade-trees and shrubbery.  Until this improvement
  was introduced and those trees planted which now render the streets of West
  Chester so umbrageous and pleasant, our pedestrians found nothing to intercept
  the glare of the summer sun, save here and there, at long intervals, a
  straggling relic of a decaying Lombardy poplar.
  In the year 1799 the
  apprehension of fire induced the formation of the first West Chester Fire Co,
  which is still kept up in good condition, with 2 other efficient companies;
  the Good Will, organized in 1833 and the Fame,
  organized in 1838.
