a large river of Western Africa; which falls into the Atlantic a considerable distance to the south of the Gambia. It appears to be now ascertained, that the three great rivers of the western coast, the Senegal, the Gambia, and the Rio Grande, have all their sources very close to each other, in a range of mountains a short distance to the north-west of Teemo, in Foota Jallo. M. Mollien's account represents the Gambia, called the Ba Diman, and the Rio Grande, called the Comba, as springing from the same basin, amid high mountains. The source of the latter stream is in latitude 10° 37' north, and longitude 11° 17' west. The correctness of this traveller's statements is confirmed by M. Caillé, who crossed his route. M. Mollien, in describing the origin of the rivers, says, that on leaving the village called Toulon, he was led to the summit of one of the mountains which bear the appellation of Badet. Below him appeared two thickets, the one concealing the sources of the Rio Grande, and the other those of the Gambia. The valley in which they are situated forms a kind of funnel, having no other outlets than the two defiles by which the rivers issue. On quitting this basin these rivers pursue their course towards opposite points. The current of the Rio Grande is at first slow and turbid, but it soon clears; and beyond the valley its direction, hitherto north-north-east, changes to the west. After receiving the Tomine or Dongo, it assumes the appellation of Kaboo, a name which also distinguishes the country between the Rio Grande, the Gambia, and the Geba river. The territories bordering on the upper part of its course are inhabited by Foulahs, and the kingdom of Foota Jallo extends along the right bank. Further down, its shores are peopled by the Biafaras, Balantes, Panels, and other tribes, and occupied by the kingdoms of Ghinata and Biguba. Near its embouchure it divides into a number of branches, forming alluvial islands, which, with others farther out at sea, compose the Archipelago of the Bissagos. The whole length of its course may be about 500 miles. It falls into the Atlantic fifty leagues to the south of the Gambia.
