The e:\Cje of a part of the great Greenland ice sheet {on the left) resting on the land, oxer which are strewn many boulders brought by the ice and left there when it melted. the shores of New^ England. From these sea-ends, icebergs con- stantly break off; and, floating away toward the south, often reach, before they melt, as far as the path followed by the steamers from the United States to Europe. Between the baj^s, where the glacier ends in the sea, the ice front rests jn the land (Fig. 22), as it did over the greater part of l\ew York and i ^^ the States further west. There it melts in the summer, supply- ing streams with water and fill- ing many small jDonds and lakes. The front stands there year after year, sometimes moving a little ahead, again melting further back so as to reveal the rocks on 83.— A scratched pebble taken from the which it formerly rested. ice of the Greenland glacier.
