through a spur of the mountain called Turumeten. This tunnel 
has had the effect desired in preventing the lake rising above 
a fixed level. Mr. A. Holmsen, who had the supervision of the 
work, has had the kindness to communicate a sketch-map 
(Fig. 7) of the surroundings of the lake, and a photograph of 
the blockading glacier with a part of the lake in the foreground,

Fic. 8.—The ice barrier in front of the lake Daemme, sketched from a photograph. 
From a dam like this we may mentally reconstruct a barrier 
capable of accounting for the lakes dammed back in olden 
time in the Dovre region. 
There are two English accounts of this lake, viz., that of 
Mockler-Ferrymann (‘‘The Daemmevand of Rembesdals Glacier 
Lake, Geogr. Jour., 1V, Dec. 1894, London, pp. 524-528) and 
that of Munro (‘‘Ona Remarkable Glacier Lake formed by a 
branch of the Hardanger-Jokul, near Eidjford, Norway, Proc. of 
the Roy. Soc. of Edinburgh, Session 1892-3, Vol. XX, pp. 53-82). 
The two Norwegian scientists, Bing and Oyen have also made 
reports on the lake.
