a river in British Guiana. Lat. at its mouth, 6° Berbice 20. N. Long. 57° 11 W. It runs from south to north, and discharges itself into the Atlantic Ocean. The coast on each side of it forms a bay at its entrance, which is nearly a mile in width, having a small island in the middle, called Crab Island, from the number of land-crabs on it. Outside the entrance of the river there is a bar of sand, over which at high tide there is seldom more than eighteen feet of water; but within, the water is of sufficient depth, and the river is navigable for ships of burden 200 miles from its mouth. On account of the bar, however, few vessels anchor here, preferring the port of Demerara.
