Seite 144 - For, behold, the Lord cometh forth out of his place, and will come down, and tread upon the high places of the earth. And the mountains shall be molten under him, and the valleys shall be cleft, as wax before the fire, and as the waters that are poured down a steep place.
Seite 172 - Immediately before us yawned an immense gulf, in the form of a crescent, about two miles in length, from north-east to south-west, nearly a mile in width, and apparently 800 feet deep. The bottom was covered with lava, and the south-west and northern parts of it were one vast flood of burning matter, in a state of terrific ebullition, rolling to and fro its " fiery surge
Seite 171 - The steep which we had descended was formed of volcanic matter, apparently a light red and grey kind of lava, vesicular, and lying in horizontal strata, varying in thickness from one to forty feet. In a small number of places the different strata of lava were also rent in perpendicular or oblique directions, from the top to the bottom, either by earthquakes, or other violent convulsions of the ground connected with the action of the adjacent volcano.
Seite 190 - The whole course of the stream from Kilauea to the sea is about forty miles. Its mouth is about twenty-five miles from Hilo station. The ground over which it flowed descends at the rate of one hundred feet to the mile. The crust is now cooled, and may be traversed with care, though scalding steam, pungent gases, and smoke are still emitted in many
Seite 189 - The atmosphere in all directions was filled with ashes, spray, gases, etc.; while the burning lava, as it fell into the water, was shivered into millions of minute particles, and, being thrown back into the air, fell in showers of sand on all the surrounding country. The coast was extended into the sea for a quarter of a mile, and a pretty sand-beach and a new cape were formed. Three hills of scoria and...
Seite 180 - ... ceased, and immediately after, flames burst from a large cone, near which we had been in the morning, and which then appeared to have been long inactive. Red-hot stones, cinders, and ashes, were also propelled to a great height with immense violence ; and shortly after, the...
Seite 172 - The sides of the gulf before us, although composed of different strata of ancient lava, were perpendicular for about 400 feet, and rose from a wide horizontal ledge of solid black lava of irregular breadth, but extending completely round. Beneath this ledge the sides sloped gradually towards the burning lake, which was, as nearly as we could judge, 300 or 400 feet lower. It was evident, that the large crater had been recently filled with liquid lava up to this black ledge, and had, by some subterranean...
Seite 97 - A fracture, or fractures, occurred near the summit of the mountain, which extended in an irregular line from the terminal point, say five miles down the north-east slope of the mountain. From this serrated and yawning fissure, from two to thirty yards wide, the molten flood rushed out and spread laterally for four or five miles, filling the ravines, flowing over the plains, and covering all those high regions from 10 to 100 or 200 feet deep.
Seite 172 - ... the sides of the great gulf, and apparently quite detached from it. The streams of lava which they emitted rolled down into the lake, and mingled with the melted mass, which, though thrown up by different apertures, had perhaps been originally fused in one vast furnace.
Seite 87 - Sometimes they resembled an inverted burning mountain with its apex pointing to the awful orifice over which it hung. Sometimes the glowing pillar would shoot up vertically for several degrees, and then describing a graceful curve, sweep off horizontally, like the tail of a comet, further than the eye could reach. The sable atmosphere of Hilo assumed a lurid appearance, and the sun's rays fell upon us with a yellow, sickly light. Clouds of smoke careered over the ocean, carrying with them ashes,...
