About seven p.m. we anchored in 20 fathoms on hard sand, the south part of _Ilha Verde_, bearing E. and the Cape of Sierra Leona, which is a low point, N. by E. about eight leagues distant. But the land over the cape is very high, and may be seen fifteen leagues off in clear weather. About six next morning we made sail for the road, and had not less than 16, 15, 10, and 9 fathoms, till we ranged north and south with the rocks which lie about 1-1/2 miles west of Cape Sierra Leona; and when one mile from the nearest shore we had seven fathoms, good shoaling between us and the rock. Immediately when past the rock we had 20 fathoms, and shoaled to 18, 16, 12, and 10 fathoms all the way into the roads, keeping very near the south shore; for a sand lies about two miles from the north shore, or a league from the south shore, and upon it the sea continually breaks. We came to anchor in ten fathoms on good ground, the point of Sierra Leona bearing W. by N. the north point of the bay N. by W. and the sand or breaker N.N.E. In the afternoon we were waved by some men on shore, to whom I sent my boat, which, leaving two hostages, brought off four negroes, who promised us refreshments. My skiff sounded between our anchorage and the breakers, finding fair shoaling, with two fathoms water within two boats length of the breach, or sand on which the sea breaks. All the previous observations of the variation, since our coming from 2° N. latitude to this place, proved erroneous; for to each distance, having reference to any meridian eastwards, there must be added 30 leagues, and from such as referred to western meridians, 30 leagues must be subtracted; for it appeared, by our falling in with the land, that the ship was so much more westerly than we supposed; myself, notwithstanding this error, being as much, if not more westerly than any of the mariners. Yet every man must trust to his own experience; for instruments may deceive, even in the hands of the most skilful. The 7th August, some negroes of a superior appearance came aboard in my boat, for whom, as for all others, we had to leave one of our men in hostage for every two of them. These men made signs that I should send some men up the country, and they would stay as hostages. I accordingly sent Edward Bradbury, and my servant, William Cotterell, with a present to the captain, or chief, consisting of one coarse shirt, three feet of a bar of iron, a few glass beads, and two knives. They returned towards night, and brought me from the captain, one small gold ear-ring, worth some eight or nine shillings; and as it was late, the hostages remained all night on board without any one in pawn for them. I sent my boat, and brought off five tons of water, very good, and easily come by.
