Eastward of Cape Upright the water was smooth; but between it and Cape Providence a heavy breaking sea was caused by the deep swell of the Pacific. Captain Stokes found an anchorage the next night in a bay under Cape Tamar; and the following evening very nearly reached another under Cape Phillip; but the darkness of a rainy night, and strong squalls, prevented their attempting to anchor in an unknown place, and the only resource was to bear up for shelter under Cape Tamar, where the previous night had been passed. Even this was a dangerous attempt; they could hardly discern any part of the high land, and when before the wind could not avoid the ship's going much too fast. While running about eight knots, a violent shock—a lift forward—heel over—and downward plunge—electrified every one; but before they could look round, she was scudding along, as before, having fairly leaped over the rock.

It was afterwards found that a great part of the gripe and false keel were knocked away. Captain Stokes's account of this day's beat will give an idea of the difficulties which the Beagle's crew encountered, in working out of the Strait.

January 31st. "The hands were turned up at daylight up anchor; but the heavy squalls that came off the high land of the harbour, rendered it too hazardous to weigh, until a temporary lull enabled us to make sail, and re-commence beating to the westward against a dead foul wind, much rain, hard squalls, and a turbulent cross sea.

"The squalls became more frequent and more violent after noon; but they gave, in daylight, sufficient warning, being preceded by dark clouds gradually expanding upwards, until their upper line attained the altitude of about fifty degrees: then came heavy rain, and perhaps hail; immediately after followed the squall in all its fury, and generally lasted fifteen or twenty minutes.

"In working to windward we frequently extended our 'boards' to the south shore (not without risk considering the state of the weather), with the hope of making out Tuesday Bay, or some anchorage thereabout; but the coast was covered with so thick a mist, that not a single point, mentioned by preceding navigators, could be recognised.

"About seven in the evening we were assailed by a squall, which burst upon the ship with fury far surpassing all that preceded it; had not sail been shortened in time, not a stick would have been left standing, or she must have capsized. As it was, the squall hove her so much over on her broadside, that the boat which was hanging at the starboard quarter was washed away. I then stood over to the north shore, to look for anchorage under the lee of a cape, about three leagues to the north-west of Cape Tamar. On closing it, the weather became so thick that at times we could scarcely see two ships' lengths a-head.

"These circumstances were not in favour of exploring unknown bays, and to think of passing such a night as was in prospect, under sail in the Straits, would have been a desperate risk; I was obliged therefore to yield the hard-gained advantage of this day's beat, and run for the anchorage whence we had started in the morning.

"It was nearly dark ere we reached it; and in entering, desirous to keep well up to windward, in order to gain the best anchorage, I went too close to the outer islet, and the ship struck violently on a rocky ledge. However, she did not hang a moment, and was soon anchored in safety."

Finding so much danger and difficulty, in proceeding with the ship, without first knowing where to run for anchorages, Captain Stokes left her in Tamar Bay, under the charge of Lieutenant Skyring; and, accompanied by Mr. Flinn, set out in the cutter, with a week's provisions, to examine the south coast.
