NORWEGIAN GLACIERS. 91 



Thus, we find it recorded, that in our central group of High 

 Mountains, the Jotunheim, both as regards the amount of perpetual 

 snow, and lakes covered wilh ice, these phenomena indicate a more 

 severe climate about the year 1850 than either during previous 

 years or subsequent ones. In this respect the statement concer- 

 ning our principal giant summit, the Galdhötind, is especially 

 interesting. On that mountain the change of climate does not 

 appear to have influenced the snows until about the years 1864 

 — 1868. And it is highly probable, that the second chief series 

 of moraines, above referred to, within the moraines marking the 

 position of glaciers in the beginning of the nineteenth century, 

 is also of contemporaneous origin with those other facts indica- 

 ting wet weather and low temperature about the middle of last 

 century. 



It is not, however, only in the Jotunheim that we meet with 

 records indicative of glacier advance at that time in the central 

 part of our country, but also on the Dovre Mountains. „It has 

 been stated," Forbes writes in 1851, „that a lake exists in the 

 hollow, but at this time it was no doubt frozen, and concealed 

 by beds of snow, and, according to M. Durocher, a small glacier 

 is lodged under the cliffs of Sneehättan. This also was of course 

 concealed by the abundance of the remaining snow." 



Leaving the snow-fields and glaciers of our interior regions 

 to scrutinize those of our western coast, we meet with the very 

 same phenomenon. 



Turning to the glaciers emanating from the Snow-field of 

 the Folgefon we meet in the first place with the Glacier of Buer 

 that has on several occasions attracted attention on account of 

 its highly remarkable oscillations. In 1864 Sexe states concer- 

 ning this glacier, that during the preceding thirty years it had 

 increased about 1375 metres. On the other side of the Folgefon 

 is situated a small lake. Mysevand, into which 50 or 60 years 

 ago a glacier called Holmaisen protruded so far as to make the 

 position of the end of the lake very doubtful. At present, how-
