Having continued eleven days in the river Gambia, and many of our people becoming affected by acute fevers, we dropt down the river on the evening of the eleventh day, departing from the country of Batti-Mansa[1], and got out of the river in a few days, so stocked with commodities as to encourage us to proceed farther; and indeed, having been so far successful, and having a plentiful supply of provisions, and every thing necessary for prosecuting the voyage, we considered as incumbent on us to attempt some farther discoveries towards the south. We accordingly steered southwards with a favourable wind; but finding the land to run a considerable way to the S.S.W. from the mouth of the Gambia, to a certain point which we took for a cape[2], we stood out to the west to gain the open sea, the whole coast to the south of the Gambia being low, and covered with trees to the waters edge. On gaining an offing, we found that the beforementioned point was no actual cape or promontory, as the shore appeared perfectly straight on the other side; yet we kept at some distance out to sea, as we observed breakers for several miles out to sea[3]. On this account we had to proceed with great caution, keeping always two men at the head of the ship, and one in the main-top, to look out for shoals and breakers; and as a farther precaution, we sailed only during the day, and came to anchor every night. In this cautious progress, our caravels sailed always one before the other, having fixed the order of sailing by lot, and changed the leader every day, in order to avoid all disputes. At the end of two days sail in this manner, always in sight of land, we discovered on the third day the mouth of a river about half a mile wide[4], and towards evening we observed a little gulf or inlet, which we supposed might be the entrance of another river; but as it grew late, we came to anchor for the night. Next morning we sailed into this gulf, and found that it was the mouth of a large river, not a great deal less in my opinion than the Gambia, and both its banks were full of very beautiful tall trees. We cast anchor within the mouth of this river, and agreed to send two armed boats on shore with our interpreters to get intelligence respecting the country, according to our usual practice. This was done accordingly, and our interpreters, brought back word that the river was called Kasamansa, from a Negro lord of that name who resided at a place about thirty miles up the river; but who was absent from his residence, on a warlike expedition against the lord of a neighbouring territory.
