Survey of Northeast Greenland. 397 
plane table surveys extremely painful. The whole of the mountain 
area east and northeast of Varderyggen which was surveyed in the 
early summer of 1908 was, however, fairly satisfactorily mapped out, 
whereas the work in the southern district of Lille Koldewey, on 
Store Koldewey and the greater part of the terrain west of Varde- 
ryggen was very incomplete. Here the details of the coast contours 
are, it is true, reliable, but indications are lacking of a number of 
small lakes, water holes and small rivers, while also the delineation 
of the mountains, especially on the mountainous Store Koldewey 
and west of Stormelven, is extremely cursory and unreliable as 
compared to the rest of the map. | 
The cartographic material is thus rather heterogeneous. The 
original representation of the relief by equidistant horizontal curves 
could at the publication only be used for small portions of the map. 
I have, therefore, preferred not to use this manner of representation, 
but have published the whole map in a homogeneous manner, by 
means of hachures for the rendering of the relief. 
Finally it must be noted that the geographical net is made on 
the basis of a provisional computation of the co-ordinates of the 
Observatory, the results of which were ф = 76°46’18”.5, 1 = 18°43’.5 
У. of Grw. At thé final computation of the co-ordinates the most 
probable values proved to be ф = 76°46’14”.6, I = 18°42’.6 w. of Grw.

At Stormkap, 10 km west of Danmarks Havn, MANNICHE had 
established an ornithological station, where he carried on systematic 
researches of the lives of birds. At MANNICHE's suggestion I, assisted 
by LINDHARD, surveyed the terrain belonging to the station. This 
cartographic task was of rather a peculiar character, in that the 
object was to represent in the map the topographic conditions which 
in a greater or lesser degree determine the lives of birds at the 
thawing season. As far as a large number of details are concerned, 
the map, which was made during the period 28/VI to 4/VII 1908 
consequently shows a series of varying conditions in such a manner 
as they appeared during the survey, which conditions especially as 
regards wading birds and swimmers play a great part. The snow 
drifts are delineated in the size and shape which they had at the 
time; the large number of small melting water rivulets which 
only exist for a few weeks are included; the lakes, the ponds and 
the Stormelven are represented by open water; the fjord ice is de- 
signated by a signature, indicating the intricate network of water 
channels on the melting ice, which net in the main follows the
