more correctly, the quartzite encloses fragments of the 

 drift material, constituting a kind of secondary con- 

 glomerate. The quartzites have not yielded any fossils, 

 so their age is uncertain, but from extrinsic evidence it is 

 considered that they cannot be more recent than the 

 Trias, and are not unlikely to be of Silurian age. 



I am informed that a somewhat parallel case is known 

 in Australia, but with that one single exception it is 

 believed to be unique. 



Dr Hans Reusch w^as the discoverer of this remarkable 

 example of ancient glaciation, and he describes it at some 

 length in the " Norges Geologiske Undersogelse " for 

 1892, with diagrams and reproductions from photographs. 



It has been stated, on the strength of certain measure- 

 ments taken at intervals of some years, that the Scandin- 

 avian glaciers are gradually advancing down the valleys. 

 I am not prepared to deny this, nor, on the other hand, 

 am I quite able to accept it as a true proposition. The 

 evidence afforded by the moraines seems to point in the 

 other direction, for they are found in all the valleys 

 w^hether occupied at the present day by glaciers or not, at 

 frequent intervals from the sea upwards, and in the case 

 of existing glaciers the moranic matter for a distance of 

 some hundred yards from the actual ice foot, has a very 

 modern appearance. This looks very much as if the ice 

 was receding. 



In connection with this glacial debris one feature which 

 astonished me was the enormous size of some of the 

 blocks of stone of which it consisted. At the foot of the 

 Bojumsbrse some of the blocks must have been of many 

 thousand tons in weight, large enough to have accommo- 

 dated a respectable quarry. 



Although there is so much evidence of disturbance, 

 such crumplings and dislocations of the rocks of Norwav, 

 and so much extreme metamorphism — by far the greater
