Right off the harbour lie several small islands, all steep to, or nearly so; a few rocks project a very small distance from some of them, but which cannot be considered dangerous, as no person possessed of common prudence would ever take a ship so near as they lye; within those islands (if you have not wind to carry your ship into the harbour) you may anchor; the best birth for getting under way with any wind, is to bring the island Raz (a low island) to bear south or south half west one mile, in 14 or 15 fathoms water, soft bottom; there is nothing in the way between this anchorage and the harbour; you will observe in the entrance a small island or rock, fortified, called Lage; you sail about mid-channel between this island and Fort Santa Cruz, observing that the tide of flood sets upon Santa Cruz point, and the ebb upon the island; the soundings from the outer anchorage decrease from 14 fathoms, where we lay, regularly, till near abreast of the Sugar-loaf, where it is six and a half fathoms: from this depth you drop into 12, 14, and 16 fathoms. Run up, and anchor off the town in 17 or 18 fathoms, clear soft ground. CITY OF ST. SEBASTIAN. Latitude: 22 deg. 54' 13" south Longitude, deduced from our time-keeper of the meridian of Greenwich, and which agrees with that laid down in the new requisite tables, but which certainly are not correct: 42 deg. 44' 00" west. Longitude, determined by two astronomers sent from Portugal for that and other purposes: 43 deg. 18' 45" west. Longitude, by an eclipse of Jupiter's third satellite, taken by Lieutenant Dawes, on the island Enchados: 43 deg. 19' 00" west. Longitude, by a mean of several distances of sun and moon taken by me at the outer anchorage: 43 deg. 11' 15" west. Longitude, by Lieutenant Bradley: 43 deg. 33' 00" west. The tide flows here at full and change of the moon, north-east by north and south-west by south, and rises between six and seven feet.
