in the middle of the valley which slopes downwards from it on 

 either side and often terminales in the head of a fjord. These 

 long Valleys have doubtles been formed by two cirque-valleys the 

 heads of which have coalesced, the rock-barrier which at once sepa- 

 rated the valleys and formed their heads having been demolished 

 in course of time, leaving the low flattened col or water-parting. 

 As examples of long-valleys or hollows proper may be mentioned 

 Skaale fjorddalen on Ostero leading from the head of Skaalefjord to 

 the head of Fiindiugfjord, its highest elevation being only 60 m.

above sea-level. Another long hollow occurs on Stromo crossing 

 the island between Kollefjord and Kvivig, its water-parting being 

 some 100 m. high. If the istands were partially submerged to a 

 depth of some 100 m., Ostero and Stromo would be divided each into 

 two separate istands. In Bordo even less would be needed to convert 

 Klaksvig and Bordovig into a sound, which would isolate the southern 

 part of the island, as the hollow (Ejde) which connects these two 

 inlets (Vigs) is very low (some 10 m.) This valley belongs to the 

 few Ejder which may be described as long-valleys. 



While most of the tjords are submerged cirque-valleys, the sounds 

 are submerged iong hollows, and Siindelaget, e. g. need only be raised 

 some 10 m. to connect Ostero and Stromo, as its lowest part is
