The greater part of the vast floor of the desert under us was as black as ink, and apparently smooth and level; but over a mile square of it was ringed and streaked and striped with a thousand branching streams of liquid and gorgeously brilliant fire! It looked like a colossal railroad map of the State of Massachusetts done in chain lightning on a midnight sky. Imagine it--imagine a coal-black sky shivered into a tangled net- work of angry fire!
Here and there were gleaming holes a hundred feet in diameter, broken in the dark crust, and in them the melted lava--the color a dazzling white just tinged with yellow--was boiling and surging furiously; and from these holes branched numberless bright torrents in many directions, like the spokes of a wheel, and kept a tolerably straight course for a while and then swept round in huge rainbow curves, or made a long succession of sharp worm-fence angles, which looked precisely like the fiercest jagged lightning. These streams met other streams, and they mingled with and crossed and recrossed each other in every conceivable direction, like skate tracks on a popular skating ground. Sometimes streams twenty or thirty feet wide flowed from the holes to some distance without dividing --and through the opera-glasses we could see that they ran down small, steep hills and were genuine cataracts of fire, white at their source, but soon cooling and turning to the richest red, grained with alternate lines of black and gold. Every now and then masses of the dark crust broke away and floated slowly down these streams like rafts down a river. Occasionally the molten lava flowing under the superincumbent crust broke through--split a dazzling streak, from five hundred to a thousand feet long, like a sudden flash of lightning, and then acre after acre of the cold lava parted into fragments, turned up edgewise like cakes of ice when a great river breaks up, plunged downward and were swallowed in the crimson cauldron. Then the wide expanse of the "thaw" maintained a ruddy glow for a while, but shortly cooled and became black and level again. During a "thaw," every dismembered cake was marked by a glittering white border which was superbly shaded inward by aurora borealis rays, which were a flaming yellow where they joined the white border, and from thence toward their points tapered into glowing crimson, then into a rich, pale carmine, and finally into a faint blush that held its own a moment and then dimmed and turned black. Some of the streams preferred to mingle together in a tangle of fantastic circles, and then they looked something like the confusion of ropes one sees on a ship's deck when she has just taken in sail and dropped anchor--provided one can imagine those ropes on fire.
Through the glasses, the little fountains scattered about looked very beautiful. They boiled, and coughed, and spluttered, and discharged sprays of stringy red fire--of about the consistency of mush, for instance--from ten to fifteen feet into the air, along with a shower of brilliant white sparks--a quaint and unnatural mingling of gouts of blood and snow-flakes!
We had circles and serpents and streaks of lightning all twined and wreathed and tied together, without a break throughout an area more than a mile square (that amount of ground was covered, though it was not strictly "square"), and it was with a feeling of placid exultation that we reflected that many years had elapsed since any visitor had seen such a splendid display--since any visitor had seen anything more than the now snubbed and insignificant "North" and "South" lakes in action. We had been reading old files of Hawaiian newspapers and the "Record Book" at the Volcano House, and were posted.
I could see the North Lake lying out on the black floor away off in the outer edge of our panorama, and knitted to it by a web-work of lava streams. In its individual capacity it looked very little more respectable than a schoolhouse on fire. True, it was about nine hundred feet long and two or three hundred wide, but then, under the present circumstances, it necessarily appeared rather insignificant, and besides it was so distant from us.
I forgot to say that the noise made by the bubbling lava is not great, heard as we heard it from our lofty perch. It makes three distinct sounds--a rushing, a hissing, and a coughing or puffing sound; and if you stand on the brink and close your eyes it is no trick at all to imagine that you are sweeping down a river on a large low-pressure steamer, and that you hear the hissing of the steam about her boilers, the puffing from her escape-pipes and the churning rush of the water abaft her wheels. The smell of sulphur is strong, but not unpleasant to a sinner.
We left the lookout house at ten o'clock in a half cooked condition, because of the heat from Pele's furnaces, and wrapping up in blankets, for the night was cold, we returned to our Hotel.
