polar fox get from one flake of ice to another by jumping on 

 the small patches of ice, always found among the big flakes. 



In summer one does not see so much of the polar fox ; 

 it is a nocturnal animal and is, in its brown-grey summer dress, 

 difficult to distinguish from the surroundings at some distance. 

 Yet we met with it in several places: in Sabine Island July It 

 one was seen; at Cape Dalton one was heard on July 20, and 

 here Deichmann found a very great fox's-den with many holes, 

 at a height of 300 — 400 m. ; in Hurry Inlet on the Liverpool 

 Kyst one was seen on August 3, the day after another; on 

 August 7 one was seen in Jameson Land ; we only noticed 

 it, because a skua flew screaming about it, else we should cer- 

 tainly not have discovered it; it disappeared quickly. It was 

 further seen at Carlsberg Fjord by Koch. Professor Nathorst 

 means that the polar wolf has decimated the foxes in these 

 regions; but sufficient evidence in favour of this theory is not 

 forthcoming. 



In the region of Angmagsalik the fox is common, and is 

 caught by the Greenlanders. On the last boat expedition of 

 Amdrup, a family of a dozen foxes were seen at the bottom of 

 Angmagsalik Fjord; they had their dwelling under a big stone; 

 there were several outlets which they made use of on being 

 turned out. 



As generally known, the arctic fox is omnivorous; it is 

 fond of berries, takes young grouses and nestlings, and devours 

 also lemmings. In winter it must often suffer much from 

 hunger; then it follows the traces of the bears. Amdrup and 

 Søren Nielsen have told me, that the bear traces in the snow 

 are almost always followed by fox traces, and it must be con- 

 tent with getting the rests from the meals of the bears; in 

 winter it is also very thievish and forward. 



In Jan Mayen the polar fox is common, several were heard 

 and seen, and Hartz shot one here on June 26. 



All the arctic foxes we saw were in summer dress ; but
