Famous quotes containing the word tract:

    When the State wishes to endow an academy or university, it grants it a tract of forest land: one saw represents an academy, a gang, a university.
    Henry David Thoreau (1817–1862)

    Every living language, like the perspiring bodies of living creatures, is in perpetual motion and alteration; some words go off, and become obsolete; others are taken in, and by degrees grow into common use; or the same word is inverted to a new sense or notion, which in tract of time makes an observable change in the air and features of a language, as age makes in the lines and mien of a face.
    Richard Bentley (1662–1742)

    My lusts they do me leave,
    My fancies all be fled,
    And tract of time begins to weave
    Grey hairs upon my head.
    Thomas Vaux, 2d Baron Vaux Of Harrowden (1510–1566)
