Not illustrated. 1894 Excerpt: ... vast arch of ice doubtless occupies all the surface of Greenland except the narrow belt next the shore, mainly on the southern and western coasts, where the higher land is now left bare. It would be most interesting to consider the general conditions of this wonderful glacier, with reference to the state of affairs during the last frozen period, for there can be little doubt that we have in the region beheld by these hardy explorers a very true picture of a continental ice-sheet, such as in a recent geological age covered the eastern part of North America as well as much of the Old World. But for our immediate purpose we need only to note the immense extent of this ice-field, its great depth, and the speed with which it moves from the interior toward the sea. So far we have but imperfect data concerning the rate at which the high northern glacier passes from the land into the sea; but it is clear that the movement is much more rapid than in the case of the relatively small ice-streams of the Alps. In the valley glaciers of Switzerland, Norway, or the Himalayas, the speed of the flow does not exceed on the average more than three feet per diem. At the berg-making fronts of Greenland it probably amounts on the average to more than thirty feet per day; that is, a strip about half a mile wide would be fed into the sea in the short summer season, and if the flow was maintained during the whole year, there would be a field nearly two miles wide discharged as floating ice along the whole front of the streams which attain the sea. There is no satisfactory basis on which to estimate the linear extent of the glacial front on the Greenland shore, but it is probably not less than two hundred and fifty miles. If this be the size, we may reckon that somewhere near five ...
