“Kilauea may be regarded as one of the safety-valves of a bottomless reservoir of melted earth, below the cooled and cooling crust on which mountains rise, rivers flow, oceans roll, and cities are multiplied as the habitations of men. It has been kept open from time immemorial, always displaying more or less of its active power. The circumambient air which carries off the caloric, sometimes aided by rain, is incessantly endeavoring to shut up this valve, or bridge over this orifice of three or four square miles of the fiery abyss. Sometimes the imperfect bridge of cooling lava is pierced with fifty or sixty large, rough, conical chimneys, emitting gas, smoke, flame, and lava; and sometimes the vast bridge is broken up, and all these cones submerged and probably fused again by the intense heat of the vast fluid mass supplied fresh from the interior. The mass rises gradually higher and higher, hundreds of feet, till by its immense pressure against the sides of the crater, aided, perhaps, by the power of gas or steam, it forces a passage for miles through the massive walls, and inundates with its fiery deluge some portion of the country below, or passing through it, as a river of fire, pours itself into the sea at the distance of twenty-five miles, thus disturbing with awful uproar the domains of old Neptune, and enlarging the dominions of the Hawaiian sovereign. “The whole island, with its ample and towering mountains, is often shaken with awful throes, and creation here ‘groaneth and travaileth in pain.’ In July, 1840, a river of lava flowed out from Kilauea, and passing some miles under ground, burst out in the district of Puna, and inundated a portion of the country, sweeping down forests, carrying everything in its way before it, and as a river a mile wide, falling into the sea, and heating the waters of the ocean, making war upon its inhabitants, and by the united action of this volcanic flood and the sea, formed several huge, rough hills of sand and lava along the shore. And still later than the above date, a similar flood has been poured from the summit of Mauna Loa, flowing with terrific force for weeks, and thus elevating a portion of the region between Mauna Loa and Mauna Kea; and so extensive and splendid was this exhibition, that it could be seen from the missionary station at Hilo, a distance of about forty miles.
