At sun-rise we stood towards the north, at the rate of two miles an hour, leaving Mbark asleep in his boat; he soon got up with us however, for he had six good rowers: he came alongside of our boat and put on board some merchandise, which had embarrassed him on account of the room it occupied. He then gave his final orders and left us, expressing his hope that every man would do his duty. The river takes a turn to the west, the banks continue low, but at this spot, the right bank was not entirely destitute of wood. At ten o’clock we came to a spot were it made an elbow towards the N. E. About half past ten we passed Co, a large village, in the environs of which we observed some tamarind-trees and ronniers: the left bank is formed by sand hills. There is a little island in the midst of the river opposite to Co; it is inhabited by five or six hundred Foulahs who have numerous flocks. At noon we found the course of the river turning towards the N. E. and we proceeded with it in that direction until half-past four, when it elbowed round to the north. At this hour we passed in front of Do. The river then stretched westward. It is still broad and deep enough for the boatmen to use their paddles in navigating. At half-past six we halted at Sa, a large village surrounded with a wall and shaded by some tamarind-trees, (_tamarindus indicus_). This was the only village with a wall which I had seen on the banks of the river since we left Isaca. Here we joined from thirty to forty large boats, all bound for Timbuctoo. Many of these vessels were of about eighty tons burthen. Sa is a rendezvous for the vessels which navigate in this direction. It is their practice to assemble at this port and to proceed on the voyage together, to guard against the depredations of a tribe in the neighbourhood of this town, who often board their boats and commit acts of violence and robbery. They are called by the natives Soorgoos, and by the Moors Tooariks. There were in the port of Sa from four to five hundred persons, seamen and inhabitants, who gazed at the flotilla. The port was covered with bales of merchandise, ready to be shipped on board the canoes. The commercial activity appeared astonishing. There was something in the appearance of the flotilla far more interesting than I could have expected to find in the interior of Africa. The bustle on every side almost made me fancy myself in a trading port of Europe. The largest vessels belong to Moors, who carry on the principal trade of the country: they form themselves into companies, and employ their canoes in conveying merchandise to Timbuctoo, where they are paid their freight in salt or cowries.
