1) either the panorama is not drawn from the cairn, or 
2) Point 4 is not Kap Schmelck. 
The first possibility cannot a priori be rejected. As one may 
take it for granted that the panorama does not form part of the 
cartographic material of the station, one might imagine it to be de- 
lineated from a position near the coast line southwest of the cairn. 
In this manner an otherwise immaterial projection of the coast near 
the standing place (the Point 2 of the panorama) might be supposed 
to cover the greater part of Vildtland, so that only the part which 
appears above Glacier A became visible.) 
In the panorama HAGEN has delineated two of the characteristic 
“sikosak” ice-blocks; their surfaces may, according to FREUCHEN, be 
supposed to lie 7 metres above that of the fjord ice.*) Measuring 
by the altitude of the two ”sikosak” blocks HAGEN’s height of vision 
becomes nearly 30 metres and 24 metres above the fjord ice. The 
mean of the two determinations gives the height of vision as about 
27 metres. FREUCHEN states that the “sikosak” blocks in the interior 
of the fjord become more and more closely packed. The result of 
this must be that the surface of the fjord which HAGEN sees, already 
at a distance of a few kilometres from his standing place, comes to 
correspond to the surface ot the “sikosak” blocks and not to the 
fjord ice proper. Leaving out of the question the foreground of the 
panorama (Point 1), for which the height of vision must be put at 
27 metres, one may thus reckon with a height of vision of about 
20m. According to this the “sikosak” horizon may be estimated at 
about 4/20 km — about 18km. The dip of the apparent horizon 
becomes about 7’.7. | 
The apparent horizon in HAGEN’s panorama has in the main a 
course as shown in Fig. 61. From this it appears that the greater 
part of the coast line falls below the 
он ee? horizon; only the stretch 1—2, as well 
j Fig. 61. as a few small skerries quite towards 
the right, can with any certainty be 
said to lie nearer to the standing place than the apparent horizon, 
in other words, presumably within a distance of about 18 km. 
1) In the subsequent examination of the panorama I take it for granted that 
HAGEN, while drawing it, had all the time faced that part of the landscape 
which at the present moment he was engaged in delineating, i. e. the panorama 
may be imagined to be drawn on the surface of a cylinder which later on has 
become unfolded. This presumption, however, will hardly be of any practical 
use, as far as the result of the examination is concerned, but only for the 
interjacent computation.
