had been formerly deposited upon the submerged floor of the 

 valley." It may be assumed that the advance of this glacier, 

 thus proved, was of only short duration and rather slight, as 

 later on a conspicuous decrease is reported to have taken place. 

 This indication of a glacier advance in this region is, however, 

 exceedingly interesting from the fact of its being almost con- 

 temporaneous with a period of slight advance in several of our 

 southern glaciers. During the decade 1880 to 1890 the condition 

 of the Glacier of Enga seems to have been stationary, as we 

 find the same distance of 800 metres given both in 1883 and 1891, 

 between the lower end of the glacier and the sea. When com- 

 pared with some other instances of an apparently stationary con- 

 dition of glaciers during this decade both in the southern and 

 the northern parts of our country, it is by no means improbable 

 that a slight increase of glaciers may have intervened between 

 the dates mentioned above. Later on, up to the year 1898, a 

 considerable decrease of this glacier took place, and the amount 

 of this decrease, from 1889 to 1898, is stated to have been from 

 60 to 80 metres. 



In the southern part of the Snow-field of Svartisen a con- 

 siderable decrease of the glacier is also observed. In the middle 

 of the nineteenth century, Forbes was informed by Munch that 

 „a considerable glacier descends to the Svartiis lake, which it 

 partly fills," and in 1873 De Seue stated that the ice-edge of the 

 glacier, protruding into the Lake of Svartis vand, was about 470 

 metres in length. Further on, a decrease of this glacier was 

 recorded in 1881 , and in 1891 a considerable decrease was stated 

 to have occurred during the previous years both as regards the 

 thickness and the length of this glacier. 



The Glacier of Jökelfjord in the north of our country is 

 extremely interesting from the fact of its descending to the sea- 

 shore. This glacier is built up in a couple of terraces, the lower 

 one being a true glacier remanié. The descriptions of this gla- 

 cier are not sufficiently precise to allow of the determination of
