itself as a bush in shrub form, and from 3 feet to 6 feet 

 6 inches in height ; but in certain plains up to Selbo, in 

 the perfecture of Sondre Drontheim, it assums a fine 

 conical form, and the proportions of a tree ; and it attains 

 to a height of 12 metres, or 40 feet. It is found every- 

 where up to the North Cape. It climbs up the moun- 

 tains, passing the limits of the birch, and attains, like 

 some of the osiers, an altitude of 1500 metres above the 

 level of the sea.

The forests in Norway, according to a statement by 

 M. F. L. Marny, in a volume treating of the forests of 

 Europe, are extensive ; but they are to a great extent 

 suspended along the Scandinavian Alps, which separate 

 this country from Sweden. The birch reaches there an 

 altitude of 365 metres. In the diocese of Bergen the fir 

 has still the gigantic proportions seen in the forests of Swit- 

 zerland and Germany ; but more to the north its size is 

 diminished to stunted proportions, and at the Polar Circle 

 it has totally disappeared ; whilst in Swedish Lapland it 

 advances yet to two degrees beyond this. In Norway 

 the birch serves as a ladder to vegetation ; it is the 

 measure of its energy, and marks by the different states
