triangulation was then to be calculated so that a minute survey 
might be begun during the following summer. 
The ınonth of September was entirely taken up by triangulation 
and base measuring. On October 1st I went on a depot trip to Jokel- 
bugten (Glacier Bay), and not until after my return could I commence 
my work in the Observatory. On October 14th the first observations 
were made at a temperature of — 20° (Centigrade). From November 
11th until December 4th I went on a sledge trip; after that I was 
at home at the station during the months of December and January, 
but on January 31st the depot trips in a northerly direction began, 
and so the observations in the Observatory wery practically at an end 
as far as that winter was concerned. 
Consequently, having only had at our disposal the period from 
October 14th to November 10th as well at the months of December 
and January, it is not to be wondered at that the result of the ob- 
servations during this winter was a very meagre one. However, we 
succeeded in determining the latitude and azimuth, as well as in 
making the necessary determinations of time, but otherwise the ob- 
servations might rather be characterized as a series of exercises, in 
the course of which we gradually learned to surmount the rather 
considerable difficulties mentioned above and chiefly caused by the 
cold. 
Taught by my experience during our first winter, I arranged 
things in such a manner as to be able to remain at the station 
during the months of September and October 1907 in order to be 
able to make use of the most favourable season in carrying out the 
comparatively difficult and protracted series of observations for the 
determination of the longitude (by azimuths of the moon). 
During our first winter I had as my assistant Lieut. HAGEN. 
After his death Dr. WEGENER and Dr. LINDHARD took up the work. 
The interest which these two men took in the observations, and the 
considerable practice which they, after a while, acquired as regards 
the practical carrying out of the observations as well as the calcula- 
tion of same was extremely useful to me. Between them they made 
half of all the observations in the Observatory. 
In the course of the preparations for the expedition Dr. WEGENER 
had applied to Professor M. SCHNAUDER, Observator at the Geodetic 
Institute of Potsdam, in order to be instructed in the purely practical 
arrangement of the observations. Professor SCHNAUDER, out of pure 
interest for the cause, not only instructed Dr. WEGENER in all the 
most important observation-methods, in particular observations of 
the moon with the attendant determinations of time, but also made 
the calculations of all of these tentative observations. In this manner
