Erebus, a noted Antarctic volcano. It stands in latitude 78 deg. S.; longitude, 170 deg. E. Its snow-clad slopes rise from the border of the great ice barrier to the crater fourteen miles inland and 13,000 feet above the level of the sea. It is an active volcano lighting up the Antarctic night with a fitful glow heightened by frequent bursts of flame from the crater. The mountain has been built up by outpourings of lava. No flow has occurred in recent times, but a column of steam shoots up at intervals of time to a height of nearly a mile, and trails away in a cloud before the wind. The crater is described as 900 feet in depth and half a mile wide. Clouds of steam fill the bowl. The observations can be made only when a favoring breeze carries the steam aside or whips the crater empty. The atmosphere is redolent of sulphur. Feldspar crystals, two or three inches in length, many of them perfect in outline, lie strewn about. They all were once imbedded in pumice stone, but, as the latter disintegrated, it was blown away in the form of dust, leaving these beautiful crystals behind. The air is so cold that huge cones of ice form about the fissures from which steam issues.
