From the earlier belief that the Greenland and American ice-sheets were united during the Glacial period there has of late been a reaction, and the pendulum has swung so far in the opposite direction that it is now said that the Greenland glacier has probably never extended so far beyond its present margin, but that many of the peaks of the islands and peninsulas bounding the Greenland insular land mass escaped glaciation. This opinion has been expressed by both Professors Chamberlin and Salisbury as a result of their recent studies upon the Greenland coast.*
My conclusions, based on a study of a part of the Greenland coast in 1896, are of a directly opposite nature. All the land studied in any detail by the Cornell party was found to have been glaciated, and we saw no reason for believing . . .
