A _ e     E yards. It is not so common in cultivated ground or meadows. Its S

    The ox—eye daisy, or field daisy, as it is sometimes called, is an I
  l introduced perennial which has become common in pastures and b
    l meadows at the East and North. It is unfortunately common lo- Sl

  l rayed flowers with yellow discs, are handsome, and otherwise well tl
  adapted for decorative uses in dwellings, yet the troublesome nature Gl
    of the plant as a weed forbids its encouragement, and it is to be P
  ; hoped that it will not become more common in th State. The · _ h
