Since corries of such typical development rarely occur in 

 a rock with such evident alternation of strata as this, i took 

 particular trouble to follow some characteristic basalt banks 

 round the front wall in order to see whether any faults had 

 contributed to the formation of the valley. It turned out that 

 really a few small irregularities occurred, pointing to some 

 minor dislocations such as are common everywhere in these 

 basalts. But it seems to be equally certain that no large faults 

 occur here, and while the first foundation of the valley as 

 usual must have stood in connection with the weakness of the 

 rock along a dislocation line, the possibility of the whole actual 

 valley originating in connection with a depression or a large 

 fault seems to be entirely excluded. 



To deduce from this any direct conclusions as to the 

 problem of the formation of the fjords is scarcely justifiable, 

 since no real analogy with the rock barriers at the entrance 

 of the fjords occurs here, but on the other hand it can scarcely 

 be doubted that numerous typical fjords, occurring in the same 

 kind of rock, have assumed an analogous stage during their 

 formation, for which reason every contribution to the history 

 of their origin is of great moment M. 



3. The Region of the Sedimentary Rocks. Between 

 Scoresby Sund (W. of Hurry Inlet) and about 74° N. lat. appears a 

 broad zone of sedimentary rocks of an age, as far as we know, 

 varying between Silurian and Jurassic, and which was made known 

 by Scoresby, Roldewey, Ryder and Nathorst. These 



h In this paper I can unfortunately not enter further into the question of 

 the formation of fjords and corries, but must content myself with re- 

 ferring to an earlier paper of my own in the Bull, of the Geol. Instit. 

 of Lppsala, Vol. IV (18У9), and to Richter, Geomorpholog. Untersuch, 

 in den Hochalpen, Peterm. MiU , lirg.-Heft 132 (1900). — Sunk below the 

 sea, these cirque-valleys seem to me to correspond to certain typical 

 lateral fjords without entrance barriers (sills). On the other hand most 

 fjords are true basins and must have originated from the direct erosion 

 of moving ice, be it with or without discharge of loose material.
