and by their comparatively regular shape (cf. fig. 26) showed 

 that they derived from a large ice-stream. Even if we agree 

 with Drygalski in confining the appelation "inland ice" to 

 such masses of ice as force their way in a mass into a — to 

 them — new district, it can be open to no doubt that that is 

 the case here, such large ice-streams being of necessity derived 

 from a very extensive collecting-area. 



On the plateau-shaped mountains at the shore of the fjords, 

 and also on the basalt masses on the peninsula to the S. of 

 Scoresby Sund, we find, as a rule, local caps of highland ice, 

 which are often spread over the mountain plateaus like even 

 and comparatively thin coverlets, as is shown in the photograph 

 fig. 28 from the environs of Polhem Dale, and also on fig. 29. 

 Such highland ice often sends down towards the deep valleys 

 narrow ice-belts which incline so abruptly that it is hard to 

 understand how a glacier under such conditions can retain its 

 continuity. Fine examples of this can be seen, for instance, in 

 Forsblad Fjord, of which the same fig. 29 gives us a picture; 

 the ice cap is here at least 1500 m above the sea. 



Of the larger coast glaciers 1 only visited one, namely 

 Bartholin Glacier, somewhat to the S. of Scoresby Sund (cfr. 

 fig. 30). According to Koch's measurements, the glacier at its 

 front has a breadth of some 3^/2 km and its perpendicular wall 

 rises from 15 — 20 m above the sea. its surface is even, almost 

 without fissures, at least on its eastern side, on which I walked; 

 towards the interior of the land it rises very slowly to begin with. 

 Further inland it seems to branch into two arms that appear to 

 rise more steeply in order to converge with the highland ice that 

 covers this district. A dark, central moraine wall, formed by pieces 

 of a scoriaceous basalt, whose cavities are filled by fine zeolite 

 crystals, runs inland as far as the eye can reach. Still larger is 

 the E. side-moraine, which forms a whole broad zone with 

 ridges and valleys and real small ice-lakes (fig. 31), and runs 

 along Henry Land right uf» to the valley which here debouches
