however, only very few specimens could be brought back and 

 these were so badly preserved that only their genus could be 

 determined. 



The Tertiary rocks in this district are closely bound to 

 the basalt, which has certainly contributed to protect these 

 easily destroyed rocks. As a result of our work in 1900 it 

 could be proved that also in the large basalt territory S. of 

 Scoresby Sund Tertiary sediments occur. I shall return to 

 these investigations directly; meanwhile a few words about our 

 observations in the N. basalt region, where I only visited 

 Sabine I. 



The Tertiary rocks have a very considerable distribution 

 here, in comparison with the S. region. In many places low 

 mountain ridges occur, formed exclusively of sandstone, and 

 also huge layers between the sheets of basalt. So for instance 

 Hasenberg is formed, to a considerable extent, of Tertiary beds, 

 and here I succeeded in finding leaves of plants, which, though 

 badly preserved, were of interest in enabling me to determine 

 positively the age of the sedimentary rocks of that place. 



Incomparably better preserved fossils were found by Hartz 

 in Germania Bjerg, in a piece of dark clay-slate of about 12 m. 

 in length, inclosed in the basalt and somewhat burnt by it. 

 This find is described by him in "Medd. om Grønland", Vol. 

 XXVII, pag. 156. The flora, however, seems to be very poor 

 in species. 



As to the pétrographie character of the rock, it is com- 

 posed everywhere of loose, yellow or grey sandstones, very 

 subordinately of dark schists. Conglomerate also occurs at 

 times with pebbles of foreign rocks, granite, etc. On the other 

 hand limestones and all rocks of red colours are lacking, even 

 more consistently than in the Jurassic beds. 



Our most resultful investigations into the Tertiary beds of 

 Greenland were carried out within the southern basalt-region. 

 From here, from Cape Brewster, Scoresby had already brought
