„Les trois glaciers de la vallée d'Olden ont été en retraite depuis 

 longtemps, d'après ce qu'on dit. En 1869 ils semblent avoir été 

 en voie de progression." And this increase of the three glaciers 

 of Olden continued down to the year 1873, according to state- 

 ments made by Anders Briksdal. During the following twenty 

 years, however, the Glacier of Briksdal as well as the other two 

 chief glaciers of Olden are said to have decreased continually. 

 In the summer of 1893, Anders Briksdal informed me that the 

 three glaciers just mentioned were then decreasing; but only two 

 years later, in 1895, he wrote to me informing me that the Gla- 

 cier of Briksdal, in the course of the last year, had increased 

 about 15 metres in length and at the same time had consider- 

 ably enlarged its borders. The other two glaciers of Olden had 

 also been increasing during the year, but not so much as that 

 of Briksdal. The Glacier of Aamot, on the other hand, had con- 

 siderably increased of late years. In the autumn of 1897 Anders 

 Briksdal favoured me with some fresh information regarding the 

 oscillation of glaciers in Olden. During the two preceding years, 

 he wrote, the Glacier of Briksdal had somewhat increased, as 

 had also the other glaciers of the neighbourhood ; but during the 

 present year this glacier had somewhat decreased, as was also 

 the case with the others. In the autumn of 1899 he informed me 

 that the three chief glaciers of Olden, as also the Glacier of 

 Aamot, had of late years been decreasing. In September last, 

 Anders Briksdal informed me that the Glacier of Briksdal as 

 well as the glaciers of Aabrække and Melkevold had decreased 

 during the. present year, 1900, the last-named having decreased 

 more than the other two. With regard to the glaciers in Olden, 

 Rasmus Aabrække stated the decrease of the Glacier of Brendal 

 from 1899 to 1900 to be 10 metres, that of the Glacier of Briks- 

 dal 5 metres, and that of the Glacier of Melkevold 15 metres. 

 Even if the system of curves, representing the oscillation of 

 the four glaciers in question, can only claim to do so roughly. 

 It is hoped that the figures on p. 55 may contribute to present
