 culus pygmœus and Saxifraga riuularis. 



Just above the Cassiope-be\t north of "The Island" (Point I) 

 the edge of the 9-metre curve was formed by a continuous growth 

 of Dry as which kept to the level, dry margin, and did not extend 

 over it in places where it ended abruptly. But Cassiope does not 

 care to climb over any edge which does not retain its snow-covering 

 very long; and thus Vaccinium is afforded an opportunity for growth

between Dryas and Cassiope, and there it is often found in a sharply 

 defined belt of 20 — 30 cm.; it occurs almost exclusively on such 

 somewhat rounded surfaces transitional between more level areas 

 and depressions in the ground. Vaccinium was found in a specially 

 well-marked area and under such conditions east of Hulesö, where 

 a large, level tract consisted ot an Eriophorum-hog of copious mois- 

 ture derived from an enormous snowdrift towards the north-east. 

 A rather broad dyke formed a boundary to the bog and was broken 

 through by small outlets from it. Upon this dyke Dryas and Vac- 

 cinium were distributed as described above. A depression of about 

 one metre in depth contained some luxuriant tufts of Empetrum
