line is not always easy to determine, especially not in the fjords. The 

 upper limit of high tide has also been used, but that is still more uncertain, 

 as the marks of high water may be much influenced by the waves and bv 

 storms. I have, therefore, started from what T estimated to be the mean 

 level of the shore-line, as marked by the colour of the rock-surface and by 

 the organic life in the shore, balanes, snails, &c., and also the sea-weed. 

 I admit, however, that this way of estimating may be more or less arbi- 

 trary, and I consider the upper fucus limit to be preferable as a l)ase 

 wherever it is fairlv distinct. 



The Strandflat of Sogne Fjord. 



Along both sides of Sogndal Fjord and Norum Fjord, in the inner 

 region of Sogne Fjord (see Figs. 21 and 22), there are very conspicuous 

 low, flat points (promontories) and benches, being obviously parts of a 

 strandflat, cut in solid rock at the base of the steep mountain sides. They 

 have an ccjual altitude of about 10 metres above sea-level. The rocks in 

 tliis region are j^artly crystalline schists overlying phyllite, partly gabbro.
