[9] Cada Mosto is exceedingly superficial in his account of the Rio Grande; and it even seems dubious if he ever saw or entered this river, as he appears to have mistaken the navigable channel between the main and the shoals of the Rio Grande for the river itself; which channel extends above 150 English miles, from the island of Bulam in the E.S.E. to the open sea in the W.N.W. This channel agrees with his description, in being twenty miles wide, whereas the real Rio Grande is greatly smaller than the Gambia.--E. [10] These may be the island of Waring and the Marsh islands, at the north-western entry of the channel of the Rio Grande, forming part of the Bissagos islands.--E. SECTION XI. _The Voyage of Piedro de Cintra to Sierra Leona, and the Windward coast of Guinea; written by Alvise da Cada Mosto._ The two voyages to the coast of Africa in which Cada Mosto was engaged, and which have, been narrated in the foregoing Sections of this Chapter, were followed by others; and, after the death of Don Henry, two armed caravels were sent out upon discovery by orders from the king of Portugal, under the command of Piedro de Cintra, one of the gentlemen of his household, with injunctions to proceed farther along the coast of the Negroes than had hitherto been effected, and to prosecute new discoveries. In this expedition, Piedro de Cintra was accompanied by a young Portuguese who had formerly been clerk to Cada Mosto in his two voyages; and who, on the return of the expedition to Lagos, came to the house of his former employer, who then continued to reside at Lagos, and gave him an account of the discoveries which had been made in this new voyage, and the names of all the places which had been touched at by Piedro de Cintra, beginning from the Rio Grande, the extreme point of the former voyage[1].
