this part of the willow bushes were often dying. There was 

 also some difference between the east side of the walls, which 

 was, as a rule, green, and the western side, which was largely 

 naked and eroded. Farther up the country were found similar 

 sandy areas with Salix] but here the walls w-ere not always 

 parallel with Ryders Elv, nor did they always follow the direc- 

 tion of the fall of the slope; the fact is that they were always 

 found on sloping ground, but were apparently diagonally placed. 

 To the north of this high sandy area the land, which is 

 now covered by a Dryas rocky-flat formation, sinks down to 

 a broad hollow by the stream, and is here, to a great extent, 

 sparely covered with Festuca rubra. The lowest part formed 

 a nearly circular spot of abt. 30 m in diameter, densely co- 

 vered by Calamagrostis neglecta of a heigh of 25 — 30 cm 

 Separate from this meadow was found along the banks of the 

 stream and raised no more than abt. 20 cm above the sur- 

 face of the latter a hydrophilous meadow, which habitually re- 

 sembled a marshy meadow, the small, sharp-edged, deep, of such 

 a meadow characteristic pools ("Lo'er", cpr. E. Warming: Dansk

 less I should not think, although 1 did not take my levels, that 

 the sea-water can force its way so far up the stream and ex- 

 pel the freshwater. The vegetation here consisted of a dense
