Fridthof Nansen, who in 1SS8 was the first to cross Greenland, compared the inland ice to the gently sloping surface of a shield hundreds or even many thousands of feet in thickness. From the inland ice glaciers, like mighty tentacles, are thrust outwards towards the sea, and as the ice reaches water deep enough to buoy up the moving mass por- tions are broken off as icebergs. One of the most prolific berg-forming glaciers on the west coast stretches across the head of the Jakobshavn Ice Fjord (lat. 69° N.). It has been calculated that the daily dis- charge of ice throug'n this ice fjord amounts to 432,000,000 cubic feet. The surface of the water as seen from the hummocky coast behind Jakobshavn is a continuous mass of icebergs, some floating, some >tranded, all huddled together in disorderly array, suggesting the fall of a stupendous avalanche into the waters of the fjord. At the western end of the fjord the icebergs set out to sea drifting, it may be, many
