RUN, a very extensive salt morass in Hindustan, which bounds the western frontier of the province of Gujerat, and communicates with the Gulf of Cutch. It is several hundred miles in length, and exhibits a variety of appearances, being in some places a widely expanded sheet of shallow water, only a few inches deep, and in others an impassable swamp. In some places it is a dry unproductive bank of sand, impregnated with saline particles, adverse to vegetation. In-
cluding its windings, it extends over many hundred miles, and sweeps round the north of Cutch. It appears at one time to have been covered with the waters of the ocean.
