southern side, the Boiumbiae and Suphellebrae, come within 480 and 170 feet of 

 sea-level. David Forbes calculated that the glaciers of this region advanced at 

 the annual rate of 167 feet, concluding that, though interrupted by a longer 

 winter, they progress more rapidly in summer than those of Switzerland.

Between July 10th and 19th the Boium glacier moved forward nearly 17 feet, or 

 at the rate of 1 foot 8 inches daily. 



Although the Norwegian snow-fields are far more extensive than those of the 

 Alps, the glaciers cannot be compared with those of Central Europe. The cause 

 of the contrast lies in the form of the mountains, those of the Alps being mostly 

 pyramidal, while the Norwegian highlands present the appearance rather of a 

 turreted wall. Thanks to the general inclination of the Alpine rocks, the snowy 

 masses move uniformly forward along the whole slope, whereas in the Norwegian 

 highlands the snow falls either on slightly inclined plateaux, or in deep gorges
