Tanner's investigations [190^1, 19071 of the raised shore-lines in Fin- 

 mark show a relation hetwcen inclinations of the planes of the twfj shore- 

 Inies which lie calls It: ami //./, i|uile similar to what ilellanrl has foun'I 

 in ihe I'romso district. As will he mentioned later, Tanner's shore-lines 

 !r and //. / correspond probably t(j the two well known shore-lines of the 

 'Fromso district and Alten. 



Tanner found [1906, p. 130] that the i)lanes of the two shore-lines 

 intersect one another about 50 kilometres north of Kvitnes (in the mouth 

 of Tana Fjord) and 80 kilometres north of Havningberg (25 kilometres 

 north-west of Wardo), at heights of 8 and 7 metres above sea-level. 



The explanation is obviously the same as before. Besides the tilted 

 upheaval of the land, there has also been an elevation of the land in its 

 horizontal position, or a sinking of the sea-level, which has the same 

 effect. And this change of level has probably lieen of about the same 

 magnitude as in the Tromsø district and in the region of Nord Fjord and 

 Sogne Fjord, or perhaps a trifle higher if we may judge from the height 

 of intersection of the two planes. 



In the region, however, of the Arranger Peninsula the plane of the 

 upper shore-line {le) will intersect the horizontal plane of elevation (the 

 plane of the lower level of the strandfiat) far outside the coast. If we 

 assume the height of the latter plane to be 18 metres the distance will be 

 about 25 kilometres north of Kvitnes (in the mouth of Tana Fjord) and 

 54 kilometres north-north-east of Flavningberg. This might seem to 

 indicate that the inland-ice, which pressed the land down, extended far 

 seawards outside the coast in this region. 



Ramsay's meastirements show a similar relation between the in- 

 clinations of the two planes of shore-lines on the Ribachi Peninsula, on 

 Kildin Island, and along the IMurmanski Coast, as well as along the south 

 coast of the Kola Peninsula. Along the east coast of this peninsula, how- 

 ever, in the region of the mouth of Ponoi River, there seems to have been 

 no postglacial upheaval of the land. 



Fig. 168 gives a profile of the heights of the two shore-lines along 

 a line at right angles to the approximate direction of the isobases in this 

 region according to Ramsay's map [1898, p. 132]. The gradients of both 

 shore-lines decrea-se outwards in a similar manner as the gradient of 

 Kaldhol's upper limit of submergence decreases seawards in the region 

 of Nord Fjord. 



According to recent statements by Ramsay [cf. A. G. Hogbom, 1921, 

 p. 137], however, the land at the entrance to the White Sea. should have 

 been so much higher than now during the lateglacial period when the ice- 

 sheet retreated from that region, that the \\'hite Sea mav have been cut 

 off from the Ocean, and transformed into a fresh-water lake, similar to
