a name given to certain fountains in Iceland, of a most extraordinary nature; forming at times jets d'eau of scalding water ninety-four feet high and thirty in diameter, creating the most magnificent gerbes that can be imagined, especially when backed by the setting sun. They arise out of cylindrical tubes of unknown depths; near the surface they expand into apertures of a funnel shape, and the mouths spread into large extent of flabelliform matter, formed of successive scaly concentric undulations. The playing of these stupendous spouts is foretold by noises roaring like the cataract of Niagara. The cylinder der begins to fill; it rises gradually to the surface, and gradually encroaches its height, smoking amazingly, and flinging up great stones. After attaining its greatest height it gradually sinks till it totally disappears. Boiling jets d’eaux and boiling springs are frequent in most parts of the island. In many parts they are applied to the culinary uses of the natives. The most capital is that which is called Geyser or Geyser, in a plain rising into small hills, and in the midst of an amphitheatre, bounded by the most magnificent and various-shaped icy mountains; among which the three-headed Hecla soars pre-eminent. See Iceland, No. 4.—These hueres are not confined to the land; they rise in the very sea, and form scalding fountains amidst the waves. Their distance from the land is unknown; but the new volcanic isle, twelve miles off the point of Reckenes, emitting fire and smoke, proves that the subterraneous fires and waters extend to that space; for those awful effects arise from the united fury of these two elements.
