The 15th we continued at anchor, as the wind was still foul. The 16th we set sail and run our course 40 leagues, being this day, according to our pilots, right under the Tropic of Cancer, in lat. 23° 30' N. The 17th we ran 25 leagues, mostly in sight of the coast of Barbary. The 18th we ran 30 leagues, and at noon, by the reckoning of our pilots, were abreast of Cape Blanco. The 22d they reckoned we were abreast of Cape Verd. The 12th of December we got sight of the coast of Guinea, towards which we immediately hauled, standing to the N.E. and about 12 at night, being less than two leagues from the shore, we lay to and sounded, finding 18 fathoms water. We soon afterwards saw a light between us and the shore, which we thought might have been a ship, from which circumstance we judged ourselves off the river Sestro, and we immediately came to anchor, armed our tops, and made all clear for action, suspecting it might be some Portuguese or French ship. In the morning we saw no ship whatever, but espied four rocks about two English miles from us, one being a large rock and the other three small; whence we concluded that the light seen during the night had been on shore. We then weighed and stood E.S.E. along shore, because the master did not rightly know the place, but thought we were still to the westward of Sestro river. All along this coast the land is low, and full of high trees close to the shore, so that no one can know what place he falls in with, except by means of the latitude. I think we ran 16 leagues that day, as we had all night a stiff gale, with much thunder and lightning.
