evenly down to the level of the lake at most places, but at others 

 there are steep cliffs with deep water close in. That Sælsoen 

 owes its origin for the most part at any rate to the sea, is shown 

 by the form of the surrounding country and by the fact, that even 

 high up in the lake I have found by its lianks pieces of drift-wood 

 and fossil shells {Mya triincata, Saxicava arcticaj. But a more de- 

 tailed description of the formation of the lake and its present 

 appearance will probably be given in the geological account of 

 the land. 



Nothing definite is known as to whether Annekssøen is at any 

 time free of ice, as the journeys made on it (April — June 1908) 

 took place before the breaking up of the ice. The thickness of 

 the ice measured on the lake (2 — 2^2 meters), the large quan- 

 tities of snow which lay on it (the direction of the lake is in line 

 with the prevailing wind, which brings the heavy snow-storms in 

 winter), its narrowness, the situation deep down between high hills, 

 its open north end towards the inland ice — all this seems to indi- 

 cate that the ice never breaks up, or at most only by the bank. My 

 companion and I cut a hole in the ice at two places, where we 

 imagined the lake might be deepest. The depth of water was the 

 same (89 meters) and the bottom grajnsh brown clay. The hydro- 

 graphical conditions are shown in the accompanying table: 



In contrast to Sælsøen (see later), the bottom-water was not 

 salt, as we had expected. I took 4 vertical hauls with a small 

 plankton net (ca. ^/2 meter in diameter) with the following result: 



1. 0—50 M. ; contents were ca. half a score of pale-white copepods, 

 2 mm. long {Maraenobiotus briicei, Rich.).
