Arrow-Grass, is a plant of which there are three species ; but two only are natives of Britain, namely, the Triglochin palustre, or Marsh, and the maritimiuni, or Sea Arrow-grass. The former is fre-quently met with in marshy grounds, and the latter near the coast, and in saline tracts. As they are eaten with avidity by sheep, for which they serve as an excellent and wholesome food, we presume strongly to recommend their culture. Ah additional motive for the propagation of the arrow-grass, may be suggested to the farmer and breeder of sheep ; because it thrives extremely well in moist and swampy places, where few other vegetables would grow.
