of llie low coast, which had already beforehand been much Icnvcred to- 

 wards sca-Ievel by tlie other agencies. It is also a striking feature here 

 on Jæderen, that the plane of the stranrlflat extends with ahnost uniform 

 heights along the coast over regions with rocks differing very much in 

 their power of resistance, a feature wdiich is characteristic of the result 

 of the shore-erosion. 



Ahlmann suggests that the erosion of the inland-ice in a previouslv 

 flat region, like Jæderen and the Stavanger Peninsula, would result "in 

 soft and still more levelled forms than l)efore" [1919, P-481. Although 

 the glacial erosion may grind the forms rounder and softer, I do not con- 

 sider it possible that it can make any extensive rocky ground more level 

 than it was before. C)n the contrary T think it will always make it less 

 level, and it is, in mv opinion, probable that it is just the glacial erosion 

 to wdiich Jæderen has been exposed after its strandfiat was finally levelled, 

 that has made its rocky ground so uneven in height as it now seems to be. 



There is no reason why the inland-ice shouhl have had any special 

 tendency to form such nearly horizontal planes just above sea-level. As 

 pointed out before, the erosion of the inland-ice and the big glaciers is 

 not limited in any way by the sea-level, but goes on equally well at all 

 levels down to the depths below the sea reached bv the moving ice. \\'hy 

 then are these planes always limited to the coasts? Whv has not the 

 inland-ice formed similar levels and horizontal rocky plains under the 

 water, and also far inland, awav from the coasts? 



The high, steep Coast between Jæderen and Lister. 



Everybody travelling southwards along the coast of Jæderen must be 

 struck by the sudden change in the whole character of the coastland in 

 the region of Ogne, about 17 kilometres north of Egersund. where the 

 mountainous land suddenly approaches the coast, leaving only a com-
