also necessary lo f<o nlu'iid of (Ik- caravans to find oiil tlic easiest passages. The cedar also 

 sconied to lie more common here than lower down; in short, the character of the forest 

 itself reminds, up here, more of the one to be found on the north side of the mountains. 

 This may he accounted for by the greater amount of moisluie on tlie heights here — 

 as is the case on the noilh side. 



A marked birch-belt above the tree limit constituting a transition zone between the 

 coniferous forest and the bare mountain, as is to be found over the greater part of Scan- 

 dinavia, was not observed by me in these regions. It is cs])ccially interesting to state this 

 fact in connection with the phytogeographic discoveries in the extreme nortli and north- 

 eastern parts of Scandinavia. For, according to the investigations ol II. Ijnoheiu;, 

 every trace of the «birch period» is wanting here, a period characterized by l)irch forest 

 mixed up with alpine types, which further to the soutli seemed lo have been the first 

 vegetation seizing the land left by the ice.

In the more elevated subalpine tracts about the tree limit are to be met with, 

 besides some of the above-mentioned plants occurring in the neighbourhood of I'st 

 Algiac, also some new ones, which seemed to be predominant here. Among plants of 

 especially frequent occurrence may be mentioned:
