"April 16th. Lieutenant Skyring went on board the Adelaide with Mr. Kirke, five seamen, and one of the Beagle's whale-boats. Mr. Bynoe, the assistant-surgeon, also went as a volunteer.
"April 17th. The Adelaide sailed to survey the Magdalen and Barbara Channels; after which she was to rejoin the Beagle at Port Gallant. She soon got into a strong southerly wind, and could make no progress, as the current was against her; she therefore again stood into the bay, and anchored.
"A sharply cold night made us remember we were far south, although the weather by day had been mild. I have said little about this anchorage, as it has already been described. The appearance of the surrounding country is striking and picturesque. Mount Tarn, with its patches of snow, rising from thick woods, and the high snow-covered mountains in the distance, with dark blue sea at their base, are very remarkable objects.
"We sailed on the 19th with the Adelaide, which had been prevented from going sooner by strong and unfavourable winds: and about noon we parted from our consort, whose course was southerly, into the Magdalen Channel, while we went towards Lyell Sound.
"I cannot help here remarking, that the scenery this day appeared to me magnificent. Many ranges of mountains, besides Mount Sarmiento, were distinctly visible, and the continual change occurring in the views of the land, as clouds passed over the sun, with such a variety of tints of every colour, from that of the dazzling snow to the deep darkness of the still water, made me wish earnestly to be enabled to give an idea of it upon paper; but a necessary look-out for the vessel, not having a commissioned officer with me who had been in the Strait before, kept my attention too much occupied to allow me to make more than a few hasty outlines. Under the high land the Beagle had but little wind, and night closed upon us before we could gain an anchorage in Lyell Sound, so we shortened sail after dark, and kept near mid channel until the morning.
"The night was one of the most beautiful I have ever seen; nearly calm, the sky clear of clouds, excepting a few large white masses, which at times passed over the bright full moon: whose light striking upon the snow-covered summits of the mountains by which we were surrounded, contrasted strongly with their dark gloomy bases, and gave an effect to the scene which I shall never forget.
"At daylight, on the 20th, we were close to Lyell Sound, and stood along its west side, looking for an anchorage, until we found a very good harbour, about a mile inside Mazaredo Point.
"I then went away, with two boats, to examine the Sound, leaving the master to sound and plan the inner harbour.
