Notes to the Maps. 
Danmarks Havn and Environs, scale 1 : 100000, PI. I. 
The triangulation in the autumn of 1906 was, as mentioned 
above, computed in the course of the winter of 1906—07. Immediately 
after my return from Peary Land towards the end of June, I stretched 
cardboard on the plane table, and on this I laid down the triangulation 
stations in scale 1 : 50000, intending to make a map of this scale 
of the entrance to Dove Bugt. I personally commenced the minute 
survey, and in the course of a comparatively short time I trained 
В. THostrup, so that he was able to continue it independently, 
assisted alternately by KOFOED, FREUCHEN, LINDHARD, G. az 
WEINSCHENK, POULSEN and others. 
The superficies, of the map, 52 x 52cm, nearly corresponded 
with an area of 680 km”, of which, however, the greater part consisted 
of water. The surveys, which were carried out with great energy, 
made such progress during the favourable summer season, that I 
began to have hopes of being able to make a topographic map of 
an area four times the size of the original one. In this manner the 
map would in a considerable degree gain in interest. I therefore set 
up paper on the second plane table for a map of scale 1 : 100000, 
also 52 x 52cm, and so that on all sides it should reach beyond 
the former. It is the result of these two plane table surveys which 
on Pl. II is published as one map, scale 1 : 100000. The soundings 
indicated in the map are, however, taken by TROLLE independently 
of the land survey. 
The part of the map measured in the course of the summer of 
1907 — the stretch between Varderyggen, Harefjeldet, Maroussia and 
Syttenkilometernæsset — satisfies the demands made on the work, 
in the circumstances rather strict demands. Here there are for each 
square kilometre plotted from five to twenty points, and in such a 
terrain this was sufficient for the purposes of a map, which might 
really be said to give all the details of the landscape. 
When in the autumn of 1907 it became evident that MyLius- 
ERICHSEN had perished, В. THosrrup had to undertake the considerable 
ethnographic work, which like the topographic survey demands that 
the most important field work is performed at the time of the year, 
when the snow hides as little as possible. It therefore became im- 
possible for Тнозтвор to continue, according to the programme, the 
topographic survey already commenced. He would, however, not 
give up the survey, and so the work was continued until late in the 
autumn of 1907 and resumed in April 1908, in other words, at seasons 
when a great number of the details were hidden under the snow, 
when progress on land was very difficult, and the cold rendered the
