solid rock (see l'ij:^s. 91 and 92). Alonj^ the coast nortliwest of Preste- 

 .skjcer, as well as outside .So^-ndal, Josinij;" Fjord, and some other places, 

 liiere are a number of low rocky islets and skerries (Fig'. 92) consisting of 

 the same kiml of rock (lahrarlorite) as tlie mainland. In connection with 

 the ledges along the shores inside, they form a low and distinctly marked 

 strandfiat in front of this high and steep coast (see the profile Fig. 93). 



The many islets and skerries along the steep coast west and southwest 

 of Hitteroi, west of IJstcr Fjord, form a similar strandfiat. 



It can hardly be dou1)ted that these shore-ledges and the low islands 

 outside, have been cut by marine denudation (shore-erosion). They are 

 in appearance perfectly identical w ith those we have founrl in Sogne Fjord 

 and Hardanger Fjord. Here along this outer coast 1 suppose all ideas 

 have to be given up that these formations could be due to base-levelling 

 by subaërial denudation, or that they might l)e remnants of the floors 

 of some preglacial valley-generation. 



From Lister to the Naze (Lindesnes). 



Like Jæderen the low j)lain of Lister is to a great extent formed 

 by quaternary (glacial j accumulations, but especially in its southeastern 

 part much rock rises to the surface of the plain, indicating a low and 

 fairly horizontal level, or probalily tw^o levels, the lower one being also 

 marked by the many low rocky islands and skerries outside the coast in 

 this region south of Farsund (Fig. 94). 



The rocks of the low land and the islands outside are chieflv Archæan 

 gneiss and granite, partly also diorite and gabbro [Reusch, 1901. p. 92]. 

 The higher mountains behind the low foreland consist chieflv of Archæan 

 gabbro or labradorite rocks further inland. 



Though there is a marked rlifference l)etwcen the low foreland, and 

 the higher land behind, the mountain-slopes do not on the whole rise so 

 abruptly from the plain as for instance in some regions of Jæderen. but
