causes considerable destruction. The same may be said 

 of the greater part of the rivers of the prefectures of 

 Nordland and of Tromso. 



' The Glommen is the greatest river in the Scandinavian 

 peninsula, if we leave out of account the continuous or 

 successive rivers in the water course of the Klarelv, the 

 Venern, and the Gotelv, in Sweden. The Glommen has a 

 length of 567 kilometres, and a basin of 40,400 square 

 kilometres. Its most important affluent is the Vormen, 

 which flows from the Lake Miosen which has for its 

 principal tributary the Guldbrandslagen, which has its 

 source from the Lesjeskogsvand, on the line separating 

 the Guldbransdal and the Romsdal. Where it joins the 

 Glommen at Naes, in Romerike, the Vormen has almost 

 equal dimensions with those of the Glommen its length 

 there being 322 kilometres, and its basin measuring 

 17,050 square kilometres, while the length of the Glommen 

 above the confluence is 435 kilometres, with a basin of 

 19,880 square kilometres. ... A little above its 

 embouchure the Glommen divides into two branches, 

 the larger of which falls into the sea, traversing the town 

 of Fredrikstadt, the lesser, immediately to the west of 

 this.' 



Of the wood floated on this river I have had occasion 

 to give some account in a preceding chapter [ante p. 10]. 



The Dramselv, the second river in Norway, passes 

 through Drammen, and falls into the Drammen fiord, a 

 branch of the Christiania fiord. It is formed by the con- 

 fluence of the water course of the Rands fiord and the 

 Bsegna immediately above the Tyri fiord, in which the 

 Dramselv has its source. Above that the water course of 

 the Rands fiord, calculated by the principal river Dokka, 

 flowing from the plateau of the Oplande, has a length of 

 141 kilometres, and a basin of 3710 square kilometres; 

 while that of Bsegna, which has its source in Filefjeld, has 

 a length of 193 kilometres, and a basin of 4800 square 

 kilometres. A little after its issue from the Tyri fiord the 

 Dramselv receives its affluent, Hallingelv, from the Hemse-
