 almost circular form, south of Finse, on the new Christiania

 applied to firn and glacier-masses, 

 equally with the more familiar brae.

 so as to form the Da'mmevatn, a 

 lake which at one time endangered

 tunnel in the rock now carries off its 

 water when the level rises undulv 

 high. 



I he Folgefonn, or Folgefond — in

 for a firn-mass giving rise to glaciers 

 — lies to the east of the Hardanger- 

 fjord, and gives rise to the Buarbr*, 

 often visited by travellers from Odde.
