Specimens of the principal strata of these islands were collected, and on the return home put into the hands of Professor Jameson, of Edinburgh, who identified them as belonging to primary and volcanic rocks.
Weddell now made for the south, crossed the Antarctic Circle in W. long. 30°, and soon came in sight of numerous ice islands. Beyond S. lat. 70°, these floes decreased in number, and finally disappeared; the weather moderated, innumerable flocks of birds hovered above the ships, whilst large schools of whales played in its wake. This strange and unexpected change in the temperature surprised every one, especially as it became more marked as the South Pole was more nearly approached. Everything pointed to the existence of a continent not far off. Nothing was, however, discovered.
On the 20th February the vessels were in S. lat. 74° 15' and W. long. 34° 16' 45".
"I would willingly," says Weddell, "have explored the south-west quarter, but taking into consideration the lateness of the season, and that we had to pass homeward through 1000 miles of sea strewed with ice islands, with long nights, and probably attended with fogs, I could not determine otherwise than to take advantage of this favourable wind for returning."
Having seen no sign of land in this direction, and a strong southerly wind blowing at the time, Weddell retraced his course as far as S. lat. 58°, and steered in an easterly direction to within 100 miles of the Sandwich Islands. On the 7th February he once more doubled the southern cape, sailed by a sheet of ice fifty miles wide, and on the 20th February reached S. lat. 74° 15'. From the top of the masts nothing was to be seen but an open sea with a few floating ice-islands.
Unexpected results had ensued from these trips in a southerly direction. Weddell had penetrated 240 miles nearer the Pole than any of his predecessors, including Cook. He gave the name of George IV. to that part of the Antarctic Ocean which he had explored. Strange and significant was the fact that the ice had decreased in quantity as the South Pole was approached, whilst fogs and storms were incessant, and the atmosphere was always heavily charged with moisture, and the temperature of surprising mildness.
Another valuable observation made, was that the vibrations of the compass were as slow in these southern latitudes as Parry had noted them to be in the Arctic regions.
Weddell's two vessels, separated in a storm, met again in New Georgia after a perilous voyage of 1200 miles amongst the ice. New Georgia, discovered by La Roche in 1675, and visited in 1756 by the Lion, was really little known until after Captain Cook's exploration of it, but his account of the number of seals and walruses frequenting it had led to being much favoured by whalers, chiefly English and American, who took the skins of their victims to China and sold them at a guinea or thirty shillings each.
"The island," says Weddell, speaking of South Georgia, "is about ninety-six miles long, and its mean breadth about ten. It is so indented with bays, that in several places, where they are on opposite sides, they are so deep as to make the distance from one side to the other very small. The tops of the mountains are lofty, and perpetually covered with snow; but in the valleys, during the summer season, vegetation is rather abundant. Almost the only natural production of the soil is a strong-bladed grass, the length of which is in general about two feet; it grows in tufts on mounds three or four feet from the ground. No land quadrupeds are found here; birds and amphibious animals are the only inhabitants."
Here congregate numerous flocks of penguins, which stalk about on the beach, head in air. To quote an early navigator, Sir John Nasborough, they look like children in white aprons. Numerous albatrosses are also met with here, some of them measuring seventeen feet from tip to tip of their wings. When these birds are stripped of their plumage their weight is reduced one-half.
