 the edge of the 9-melre curve was i'ormed by a continuous growth 

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

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

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

 very long; and thus Vaccininin is nITorded 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. Vacciniiim was found in a specially 

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

 a large, level tract consisted ot an Eriophorum-bog 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
