BRAVAIS ON LINES OF FORMER SEA-LEVEL IN FINMARK. 539 



The same line appears again at Cape Krognses, where there is 

 also a little terrace shut in between two piles of rock, which 

 reminds one, by its situation, of the banks of gravel formed in 

 narrow seas. This terrace is entirely made up of sand and sedi- 

 mentary debris, and its length is about 50 metres. To the west of 

 the Cape the same terrace reappears still more distinctly, but pro- 

 ceeding onwards in the same direction (towards the west) it is 

 found coasting a part of Meelvig, where it may be observed on the 

 steep face of the mountain as a line of erosion, only indicated by 

 the difference of the angle of the slope above and below it. The 

 mean height of the line here is 24*5 m . 



This line has not been traced with certainty in the little creek 

 of Talvig*, but an alluvial terrace, almost accurately horizontal, 

 exists at an elevation of 56'5 m above the waters of the fjord. 



The two altitudes just recorded of these lines of terrace at 

 Krognaes and Talvig are, it will be seen, sensibly different from 

 those obtained in the southern part of the Alten-fjord, and the 

 differences are too considerable to be referred to errors of observa- 

 tion. Ought we to suppose that they mark distinct periods of ele- 

 vation, or is it not possible that the same line of ancient level is 

 now seen at different elevations, varying according to the distance 

 from the coast ? This latter supposition is rendered almost a cer- 

 tainty by other observations we shall have to record. 



The western part of the Alten-fjord offers no certain trace of 

 the phenomena at present under consideration ; but in the narrow 

 bay of Komag-fjord the scene changes, and our two lines of ancient 

 level reappear together, and are continued in the Leered-fjord to 

 the steep face of the rock called Quasnklubb. The mean of four 

 observations of height gives 49*6 m as the height of the upper line, 

 and two sets of observations of the lower line give respectively 

 20*5 m and 18*5 m . There can be no doubt that the upper line is 

 identical with that of the terraces of Sandfald and Quaenvig, since 

 no higher line can be traced even on the Quasnklubb, a rock very 

 favourably situated for preserving the indications of the former 

 presence of water. 



With regard to the lower line, the two measurements are pre- 

 served, because they show more clearly the probability of a 

 gradual diminution in the amount of elevation of the ancient level 

 suggested by other observations. 



The upper line re-appearing on the western side of the Komag- 

 fjord presents itself there in a manner not easily recognised, and 

 requiring, it would seem, favourable circumstances of time and 

 weather to make out distinctly. Seen at a distance it appears as a 

 perfectly horizontal line, traceable on the flanks of the mountain 

 for a distance of nearly four miles ; but it is from the opposite 

 bank of the fjord, and in the afternoon, that it is best seen ; since on 



* Talvig, Meelvig — the bays of the pine and of corn. It is interesting to 

 remark that the pine at the present day is not seen beyond Storvig, and the last 

 barley appears at Elvebakken ; but this is only additional proof that the tem- 

 perature has diminished in these regions even within the historic period.
