could see streams of lava pouring down its sides until lost beneath the snow which descended from a few hundred feet below the crater, and projected its perpendicular icy cliff several miles into the ocean. Mount Terror was much more free from snow, especially on its eastern side, where were numerous little conical crater-like hillocks, each of which had probably been, at some period, an active volcano; two very conspicuous hills of this kind were observed close to Cape Crozier. The land upon which Mount Erebus and Terror stand comprised between Cape Crozier and Cape Bird, had the appearance of an island from our present position; but the fixed ice, not admitting of our getting to the westward of Cape Bird, prevented our ascertaining whether it was so or not at this time.
The day was remarkably fine; and favoured by a fresh north-westerly breeze, we made good progress to the E.S.E., close along the lofty perpendicular cliffs of the icy barrier. It is impossible to conceive a more solid-looking mass of ice; not the smallest appearance of any rent or fissure could we discover throughout its whole extent, and the intensely bright sky beyond it but too plainly indicated the great distance to which it reached to the southward. Many small fragments lay at the foot of the cliffs, broken away by the force of the waves, which dashed their spray high up the face of them.
Having sailed along this curious wall of ice in Jan. 29.perfectly clear water a distance of upwards of one hundred miles, by noon we found it still stretching
