shrubs of Bhamnus and the bogged interior. In the west, where 

 the interior is drier and has the character of prairie, the strip of 

 Vaccinium fails. Here on this side the Bhamnus is more vigorous. 



Among the alders a few other trees are found in the wood. 

 On the northern point of the island a tall birch stands, the tallest 

 tree of the island. To north-east grow several low birches. Both 

 species of Betula are found. Of Sorbus aucuparia four trees are 

 found, of Sorbus suecica a single one, and moreover several specimens 

 of Betula and Sorbus aucuparia lower than one meter. In the 

 northern part of the island stands a little spruce inside the Bham- 

 nus-he\t. A little to the west of this stand three small shrubs of 

 Juniperus. To the north-east is found a little juniper in the deep 

 shade of the wood and a little further down the eastern coast 

 again a little juniper in the wood. 



The soil is stony, but the stones are mostly covered with peat, 

 somewhere lose and decomposing, elsewhere hard and solid as 

 raw-humus. The wood has everywhere three stories, in which 

 quality it differs from the common deciduous forests in the neigh- 

 bourhood, but as to the under-vegetation it can be divided into 

 the same subformations as the neighbouring forests on similar 

 soils or into forms intermediate between them. In the following 

 pages shall be referred to these subformations named with the 

 same numbers, under which they are designed in the formerly 

 cited pamphlet 1 ).
