plained by discharge from glacier rivers which, like those we 

 know from the south of Iceland, have often changed their bed, 

 and, undoubtedly, large portions of the district were once covered 

 by lagoons, where icebergs laden with blocks of stones floated 

 about. These lagoons must have been shut off partly by the 

 ice itself, partly, perhaps, by the mountain mass of Liverpool 

 Land. Still, it is striking that with the present climate of these 

 altitudes it is impossible to imagine either higoons or well 

 watered streams. Either the land once lay much lower, which, 

 as we have seen, is probable for other reasons^), or we here 

 have traces of some interglacial period with a warmer climate 

 than the present. 



A more detailed study of this .interesting district and its 

 loose deposits, as well as of its temperature and atmospheric 

 precipitation, is strongly to be recommended to every expedition 

 that finds its way to these parts. 



5. The Inner Central Mass of ArchaicRocks. There 

 is, of course, no detailed description of the topography of the 

 surface of the land in the interior of Greenland, since the whole 

 territory is covered with ice. It is, however, probable that the 

 territory forms a mountainous country intersected by valleys, 

 which may be inferred from observations taken at the borders. 

 At the same time, already Nansen has expressed the opinion 

 that it is "indisputable that the topography in the interior of 

 Greenland is at least as cut up and varied as in the Norway 

 of to-day". I can scarcely subscribe to this opinion, and the 



') I have also come across deposits at other places at a considerable 

 elevation, which recalled old gravel beaches, as for instance at Cape 

 Borlase Warren in an open position out towards the sea at close upon 

 300 m in height. The rocky bed here consists of basalt and also 

 some sandstone of presumably Tertiary Age. On the slope there are 

 numerous boulders of chiefly archæan rocks; to assume that these have 

 been transported by the activity of running water is not easy. However, 

 the district is too little known for a definite explanation to be given; 

 one possibility is that these stones derive from conglomerates that might 

 be found in the tertiary sandstone.
