a district in the south of Norway, comprising the valleys of the Otter river and its tributaries. The river rises in the fjelds above the Bukken Fjord, and flows south to Christiansund. The natives preserve old customs and an individual costume. A railway follows the valley to Byglands Fjord (48 m.), on the lake of that name, fostering the local agricultural and timber trade, and a driving road continues to Viken i Valle from which bridle-paths lead to Dalen in Telemarken, and over the Enden and Malen fjelds to Lake Suldal on the Bratlandsdal route.
