it contains or has contained a lake. In the course ot time this 

 lake has doubtless become filled up with fallen débris or matter. 

 The numerous fjords are also rock-basins, as is demonstrated by 

 the faet that they generally have a barrier across their entrance. 



As previously mentioned, the direction of the striæ varies con- 

 siderably, which is also the case with that of the ice-flow, as the 

 position of the »Stoss- and Leeseiten« of the »roches moutonnées« 

 indicates. As the latter are far more numerous than the striæ, they 

 afford clearer evidence as to the slaciation. It must be noticed

that the direction is from the mountains seawards through the 

 vallej^s — in other words, that the Færoes were covered by a separate 

 ice-sheet, which unlike the mer de glace of Shetland had doubtless no 

 connection with the great Scandinavian ice-sheet. This local Færoese 

 ice naturally forced its way through all the valleys and fjords 

 wdiich were thereby deepened. It must have been a buge mass, 

 as the glaciated contours appear up to a height of some 500 metres 

 but above that level there is no trace of glacial abrasion, it may 

 therefore be assumed that this overlying part was covered by névé 

 of which, however, there are no distinct traces remaining; it must 

 moreover be remembered that the atmospheric erosion would 

 make itself more felt at that height, so that any traces of névé 

 which might have existed would have been obliterated.
