Circle (66° 32′ S.) and roughly in that part of the world which lies to the south of Australia. Ross, "impressed with the feeling that England had ever led the way of discovery in the southern as well as in the northern region, ... resolved at once to avoid all interference with their discoveries, and selected a much more easterly meridian (170° E.), on which to penetrate to the southward, and if possible reach the magnetic Pole."[8]
The outlines of the expedition in which an unknown and unexpected sea was found, stretching 500 miles southwards towards the Pole, are well known to students of Antarctic history. After passing through the pack he stood towards the supposed position of the magnetic Pole, "steering as nearly south by the compass as the wind admitted," and on January 11, 1841, in latitude 71° 15′ S., he sighted, the white peaks of Mount Sabine and shortly afterwards Cape Adare. Foiled by the presence of land from gaining the magnetic Pole, he turned southwards (true) into what is now called the Ross Sea, and, after spending many days in travelling down this coast-line with the mountains on his right hand, the Ross Sea on his left, he discovered and named the great line of mountains which here for some five hundred miles divides the sea from the Antarctic plateau. On January 27, "with a favourable breeze and very clear weather, we stood to the southward, close to some land which had been in sight since the preceding noon, and which we then called the High Island; it proved to be a mountain twelve thousand four hundred feet of elevation above the level of the sea, emitting flame and smoke in great profusion; at first the smoke appeared like snowdrift, but as we drew nearer its true character became manifest.... I named it Mount Erebus, and an extinct volcano to the eastward, little inferior in height, being by measurement ten thousand nine hundred feet high, was called Mount Terror." That is the first we hear of our two old friends, and Ross Island is the land upon which they stand.
"As we approached the land under all studding-sails we perceived a low white line extending from its eastern extreme point as far as the eye could discern to the eastward. It presented an extraordinary appearance, gradually increasing in height as we got nearer to it, and proving at length to be a perpendicular cliff of ice, between one hundred and fifty and two hundred feet above the level of the sea, perfectly flat and level at the top, and without any fissures or promontories on its even seaward face."[9]
Ross coasted along the Barrier for some 250 miles from Cape Crozier, as he called the eastern extremity of Ross Island, after the commander of the Terror. This point where land, sea and moving Barrier meet will be constantly mentioned in this narrative. Returning, he looked into the Sound which divides Ross Island from the western mountains. On February 16 "Mount Erebus was seen at 2.30 A.M., and, the weather becoming very clear, we had a splendid view of the whole line of coast, to all appearance connecting it with the main land, which we had not before suspected to be the case." The reader will understand that Ross makes a mistake here, since Mounts Erebus and Terror are upon an island connected to the mainland only by a sheet of ice. He continues: "A very deep bight was observed to extend far to the south-west from Cape Bird [Bird was the senior lieutenant of the Erebus], in which a line of low land might be seen; but its determination was too uncertain to be left unexplored; and as the wind blowing feebly from the west prevented our making any way in that direction through the young ice that now covered the surface of the ocean in every part, as far as we could see from the mast-head, I determined to steer towards the bight to give it a closer examination, and to learn with more certainty its continuity or otherwise. At noon we were in latitude 76° 32′ S., longitude 166° 12′ E., dip 88° 24′ and variation 107° 18′ E.
"During the afternoon we were nearly becalmed, and witnessed some magnificent eruptions of Mount Erebus, the flame and smoke being projected to a great height; but we could not, as on a former occasion, discover any lava issuing from the crater; although the exhibitions of to-day were upon a much grander scale....
"Soon after midnight (February 16-17) a breeze sprang up from the eastward and we made all sail to the southward until 4 A.M., although we had an hour before distinctly traced the land entirely round the bay connecting Mount Erebus with the mainland. I named it McMurdo Bay,
