a name given to certain fountains in Iceland, of a most extraordinary nature; forming at times jets d'eaux 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 italacitical matter, formed of successive fealy concentric undulations. The playing of these stupendous spouts is foretold by noises roaring like the cataract of Niagara. The cylinder begins to fill: it rises gradually to the surface, and gradually increases 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 huers 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 Reickenes, emitting fire and smoke, proves that the subterranean fires and waters extend to that space; for those awful effects arise from the united fury of these two elements.
