Walking across the congealed masses of lava next morning, one began to think that at any moment one was liable to drop through to the very gates of Hades and be precipitated to the most horrible of deaths. Underneath one was a bottomless abyss of mud, sulphur, and rock; and to contemplate being cast into that fearsome-looking lake of fire and brimstone was not at all comfortable. The Biblical description of hell does not convey even a faint idea of that terrible lake of fire below us, which appeared to be fretting and fuming as though anxious to get loose and destroy everything in its path. The crater of Makuaweoweo at that time, without doubt, afforded the spectator a more awe-inspiring display of the forces of Nature than has been granted to man elsewhere on earth without the sacrifice of life. [Illustration: THE AUTHOR AND HIS COMPANIONS AS THEY APPEARED JUST BEFORE LEAVING THEIR HORSES TO VISIT THE WORST OUTBREAK. _From a Photograph._] Soon after daylight we prepared for the descent to the point that was throwing out molten lava at a white heat. It was practically impossible to take the horses farther, so we tethered them to stones near the yawning depths of Makuaweoweo, and left one of the guides to look after them. We were very thirsty, but it was some time before we could find water, though snow and ice were plentiful. Farther down, however, we discovered water in a deep crack in the lava, filled the canteens, and started on our downward journey. I was suffering from mountain sickness; my head felt as if it would burst and my stomach was upside down. We stumbled along with difficulty for about two miles, when I had to get the assistance of Mr. Buck to carry my camera. Two of our party who had started out in advance gave it up and returned--they could not stand the strain of the rough travelling. This left but four of us, with two guides. Presently we reached a cone where the lava had piled up to the height of about one hundred feet, then, bursting out at the side, disappeared into the ground, to reappear about a quarter of a mile farther down and repeat its action. These cones averaged two hundred feet in width at the base and one hundred feet in height, and we passed five “dead” ones. A sixth was still smoking, but was not active. Two of the party tried to climb to the top of this cone, but were unable to do so.
