name given by sailors to a great quantity of ice collected into one huge solid mass, and floating about upon the seas near or within the polar circles. The motion of the lesser pieces is as rapid as the currents; the greater, which are sometimes two hundred leagues long, and sixty or eighty broad, move slowly and majestically; often fix for a time, immovable by the power of the ocean, and then produce near the horizon that bright white appearance called the ice-blink. The approximation of two great fields produces a most singular phenomenon; it forces the lesser (if the term can be applied to pieces of several acres square) out of the water, and adds it to the surface; a second, and often a third succeeds, so that the whole forms an aggregate of a tremendous height. These float in the sea like so many rugged mountains, and are sometimes five or six hundred yards thick; but the far greater part is concealed beneath the water. These are continually increased in height by the freezing of the spray of the sea, or the melting of the snow which falls on them. Those which remain in this frozen climate receive continual additions; others are gradually wafted by the northern ICEBERGS are large bodies of ice filling the valleys between the high mountains in northern latitudes. Among the most remarkable are those of the east coast of Spitzbergen. The glaciers of Switzerland seem contemptible when compared to these, but present often a similar front into some lower valley. At times immense fragments break off and tumble into the water with an alarming splash. Frost sports wonderfully with these icebergs, and gives them majestic and singular forms. Masses have been seen assuming what an Arabian tale would scarcely dare to relate. Icebergs are the creation of ages, and receive annually additional height by the falling of snows, and of rain, which often instantly freezes, and more than repairs the loss occasioned by the influence of the sun.
