is due to HAGEN (Danmarks Fjord, Hagens Fjord, Independence Fjord), 
was drawn by himself in map sketches made. during the journey. 
When on May 28th 1907 I left the sledge party of MyLius-ERICHSEN 
at Kap Rigsdagen, HAGEN showed me one of his journals. Here, on 
the spot itself, he had in the observation journal for every station 
made a little croquis, based upon a rough computation of the 
observations. Later on during the enforced summer stay in Dan- 
marks Fjord he worked up these little map sketches into one map. 
Together with a few of Hacen’s sketches this map") was, after the 
death of HAGEN and MyLius-ERICHSEN, brought to the depot on Lam- 
berts Land by JORGEN BRONLUND, and here I found the sketches by 
BRONLUND’s dead body, when in March 1908 I travelled north in 
order to obtain news of our three ill-fated comrades. 
As HAGEN lacked the means of a more accurate computation, in 
particular as far as the longitudes were concerned, his maps must 
necessarily suffer from certain drawbacks, which defect was, how- 
ever, compensated for by a fortunate circumstance. When in May 1907 
I went south from Kap Kjøbenhavn (Peary Land), I myself made the 
necessary observations for the determination of the position of Kap 
Rigsdagen, as well as of the direction to Kap Knud Rasmussen, and 
in this manner I was able to make a fairly accurate geographical 
network for HAGEN’s map. 
On “Nordost-Gronland, Sydlige Blad” two sledge routes 
are indicated: Bistrup’s route in April—June 1908 to Bessels Fjord 
and the district round Teufelkap, and Mytius-ErIcHsen’s route in 
November—December 1906 to Shannon Island and Pendulum Islands. 
The object of the latter voyage was not a cartographic one. It is 
remarkable in that it was performed by untrained men, in an un- 
known terrain and after the dark season had set in; it is characteristic 
of MyLius-ERICHSEN by the courage, recklessness and good luck with 
which he carried it through. 
Two of the far-going sledge journeys of cartographic importance 
are indicated by the observation stations: J (JARNER, May 1908 to 
the interior of Ardencaple Inlet) and H (HAGEN, October 1908 to the 
southern part of Jökelbugten). 
On the map, scale 1 : 500000 the route is delineated for a series 
of journeys, the object being a cartographical one, that is: 
Kocu, August 1906 to Skerfjorden and Germania Land; 
TROLLE, October 1906 to Skærfjorden; 
HAGEN, October 1906 to the southern part of Jökelbugten; 
Bistrup, 1906, 1907 and 1908 in and around Dove Bust.
