The pit, the lake of fire, is Halemaumau, commonly translated "The House of Everlasting Fire"; the correct translation is "The House of the Maumau Fern," whose leaf is twisted and contorted like some forms of lava. Two miles and a little more from Halemaumau, on a part of the ancient crater wall, stands the Hawaiian Volcano Observatory, which is under the control of the Massachusetts Institute of Technology. The observatory was built for the special purpose of studying the pit of fire, the risings and fallings of whose lavas bear a relationship toward the volcanism of Mauna Loa which is scientifically important, but which we need not discuss here.

The traveller enters Hawaii by steamer through Hilo. He reaches the rim of Kilauea by automobile, an inspiring run of thirty-one miles over a road of volcanic glass, bordered with vegetation strange to eyes accustomed only to that of the temperate zone—brilliant hibiscus, native hardwood trees with feathery pompons for blossoms, and the giant ferns which tower overhead. On the rim are the hotels and the observatory. Steam-jets emerge at intervals, and hot sulphur banks exhibit rich yellows. From there the way descends to the floor of the crater and unrolls a ribbon of flower-bordered road seven miles long to the pit of fire. By trail, the distance is only two miles and a half across long stretches of hard lava congealed in ropes and ripples and strange contortions. Where else is a spectacle one-tenth as appalling so comfortably and quickly reached?

Halemaumau is an irregular pit a thousand feet long with perpendicular sides. Its depth varies. Sometimes one looks hundreds of feet down to the boiling surface; sometimes its lavas overrun the top. The fumes of sulphur are very strong, with the wind in your face. At these times, too, the air is extremely hot. There are cracks in the surrounding lava where you can scorch paper or cook a beefsteak.

Many have been the attempts to describe it. Not having seen it myself, I quote two here; one a careful picture by a close student of the spectacle, Mr. William R. Castle, Jr., of Honolulu; the other a rapid sketch by Mark Twain.

"By daylight," writes Castle, "the lake of fire is a greenish-yellow, cut with ragged cracks of red that look like pale streaks of stationary lightning across its surface. It is restless, breathing rapidly, bubbling up at one point and sinking down in another; throwing up sudden fountains of scarlet molten lava that play a few minutes and subside, leaving shimmering mounds which gradually settle to the level surface of the lake, turning brown and yellow as they sink.

"But as the daylight fades the fires of the pit shine more brightly. Mauna Loa, behind, becomes a pale, gray-blue, insubstantial dome, and overhead stars begin to appear. As darkness comes the colors on the lake grow so intense that they almost hurt. The fire is not only red; it is blue and purple and orange and green. Blue flames shimmer and dart about the edges of the pit, back and forth across the surface of the restless mass. Sudden fountains paint blood-red the great plume of sulphur smoke that rises constantly, to drift away across the poisoned desert of Kau. Sometimes the spurts of lava are so violent, so exaggerated by the night, that one draws back terrified lest some atom of their molten substance should spatter over the edge of the precipice. Sometimes the whole lake is in motion. Waves of fire toss and battle with each other and dash in clouds of bright vermilion spray against the black sides of the pit. Sometimes one of these sides falls in with a roar that echoes back and forth, and mighty rocks are swallowed in the liquid mass of fire that closes over them in a whirlpool, like water over a sinking ship.

"Again everything is quiet, a thick scum forms over the surface of the lake, dead, like the scum on the surface of a lonely forest pool. Then it shivers. Flashes of fire dart from side to side. The centre bursts open and a huge fountain of lava twenty feet thick and fifty high, streams into the air and plays for several minutes, waves of blinding fire flowing out from it, dashing against the sides until the black rocks are starred all over with bits of scarlet. To the spectator there is, through it all, no sense of fear. So intense, so tremendous is the spectacle that silly little human feelings find no place. All sensations are submerged in a sense of awe."
