area in the plateau landscape. An opportunity of this kind did, how- 
ever, not offer itself. 
In the autumn of 1907 a meteorological station was established 
at Pustervig, 62 km west of Danmarks Havn. On that occasion 
WEGENER asked me to determine the altitude of the mountains round 
Pustervig, and as this locality belonged to the plateau landscape, I 
determined, on the same occasion, to try to make a small topographic 
map of the locality. 
As the telescope of the universal diopter had a far too small 
play in the vertical plane, so that the instrument could not be used 
to advantage in the terrain in question, I made up my mind to 
perform the measuring with the universal instrument. The idea was 
to undertake a primitive base measuring and triangulation in the 
fjord and the valley of Pustervig, and simultaneously with the tri- 
angulation to determine by intersection of bearings the points ne- 
cessary for a rough and ready map sketching. The work was, if 
possible, to be continued on the plateau itself. 
WEGENER and I performed the measuring experiment during the 
first half of November 1907. The altitude of the mountains was 
determined, but otherwise the attempt failed, the season being far 
too advanced. The sun had disappeared; the twilight only lasted 
for three hours, so that the daily working period in the field was 
short, to which must be added that the temperature was rather low, 
and that the snowdrift almost incessantly hid the terrain from us. 
After rather painful experiments, extending over a period of eight 
days, we gave in. The plateaus, which were 800 metres in height, 
we did not even succeed in climbing in the course of this experi- 
ment. 
At that time I considered the material collected valueless and 
only used it as a little Christmas joke. For meteorological reasons 
WEGENER wished me to compute the altitudes ot the mountains at 
the earliest possible moment. The material had consequently to be 
prepared at once, and I therefore at the same time sketched the 
contours of a small map of Pustervig, in order to give WEGENER an 
impression of the situation of the levelled points. On the basis of 
this sketch the two artists of the expedition, AAGE BERTELSEN and 
ACHTON Frus, made a card, which as a humorous Christmas 
greeting was sent to PETER FREUCHEN at Pustervig on Christmas Eve, 
1907. 
Later on I found out that this sketch, though cartographically 
most incomplete, might, however, be of scientific interest. I have 
consequently published it in this place, with a few immaterial alter- 
ations, but otherwise as it was sent to FREUCHEN.
