the mountains terminate in crests or peaks only oii the narrow Islands 

 (se Fig. 17). The slopes consist of steep walls of bare lirown rock, the 

 so-called »Hamre«, broken by ledges, which latter however are not 

 flat but sloping, on account of the fallen blocks and débris which 

 have accnmulated there in as large masses as the law of gravitation 

 will allow. These slopes which alternate with the steep walls of 

 brown rock (Hamre), are cailed »Lier« or »Brækker« (Figs. 4, 5). In the 

 course of time such qnantities of rough débris have accnmulated in 



Fig. 4. StrOino. Stigafjceld scen fiom N. \V. The top part of the moimtain consists of mimcrous terraces 

 of basalt rock. Below these débris and detached pieces of rocks are lying" in wedge-like masses on the hill- 

 side. Further down again basalt rocks are distinctly seen and gently sloping hill-sides (Li). From the

the lower parts of the mountains as to conceal with a few exceptions 

 all the »Hamre« and to form slopes which are generally clothed 

 with grass. But higher up the steep brown walls of rock are almost 

 always conspicuous and on the intervening sloping ledges, made 

 up of loose débris a solitary plant is only rarely to be found. As 

 a rule the basal part of the mountains up to a height of 3 — 500 m. 

 have rounded contours or outlines and are covered with grass. 

 Above this basal part tower the bare, lofty, isolated rocks separated 

 by passes (Skard) of which only a few are at a higher elevation 

 than the above-mentioned grassy base. The passes occur at the
