inland ice conveys its supplies from the central parts of Greenland 
out to the coast. 
The surface of the marginal zone of the inland ice is undulating. 
The ice rises in large, but little pronounced terraces, towards the 
interior of Central Greenland, and thus vaguely and roughly reflects 
the relief of the underlying land. In the marginal zone we can still 
faintly trace the mountain ranges and the chief valleys, and further 
one may see, how the great ice streams, which as glaciers pass 
beyond the eircumference of the inland ice, continue as streams up 
to more than a hundred kilometres into the inland ice. The stronger 
motion of the stream appears immediately from the systems of cre- 
vasses, whereas the surrounding areas of ice lie comparatively 
quiescent. 
If one gets inside the marginal zone, the reflection of the relief 
of the underlying land ceases after a while. The interior of Green- 
land is a quite even névé without crevasses or the least indication 
of the forms of the terrain, which it conceals. However, to deduce 
from this that the ice in the interior of Greenland is in a quiescent 
state would be incorrect. In the upper layers the motion is chiefly 
vertical 9: the layers sink slowly downwards to be carried away 
through large ice-currents in the deep. These currents follow the 
large depressions of the country, irrespective of whether in this 
manner they come to pass across isolated peaks, smaller plateaus 
or low spurs from the ranges of mountains. 
In spite of the quite homogeneous motion in the surface of the 
névés of Central Greenland, we must thus suppose the motion in 
the deep to be widely different in the different places; and so also 
the landforms, which appear when the inland ice melts away, are 
of a different type. 
Keeping the map of Northeast Greenland in view it is not diffi- 
cult to construct the chief features of the lines of motion followed 
by the inland ice, when it extended beyond the coast land and 
practically concealed it altogether; it is Dove Bugt and Jokelbugten, 
which have formed the two chief drains. | 
Storstrommen and Bistrups Bre existed then, as they do now, 
but concealed in the deep below an inland ice which extended over 
Dronning Louises Land and Germania Land. After having, as they 
do now, joined off the middle of Dronning Louises Land, they bent 
towards the east, across Dove Bugt, the northern part of the united 
current passing across the country north of Edvards ©, whereas the 
southern part swept across the islands between Teufelkap and Kap 
Niels. At the same time smaller ice currents in the deep passed 
through Hellefjord, Morkefjord, Sælsøen and Annekssoen into the
