HAB. Woods, heaths and mountains, abundant. 



This is the Lichen which, for the greater part of the year, and espe- 

 cially in winter, is the support of the vast herds of rein -deer, in 

 which consists all the wealth of the Laplanders. No vegetable, 

 Linnaeus tells us, grows throughout Lapland in such abundance as 

 this, especially in woods of scattered pines, where, for very many 

 miles together, the surface of the sterile soil is covered with it as 

 with snow. On the destruction of forests by fire, when no other plant 

 will find nutriment, this Lichen springs up and flourishes, and, after 

 a few years, acquires its greatest size. Here the rein-deer are 

 pastured : and, whatever may be the depth of snow during the long 

 winters of that climate, they have the power of penetrating it and 

 obtaining their necessary food. Linnaeus has given a beautiful 

 description of this Lichen, and of the animals whose support it is, 

 in the Flora Lapponica, p. 332, which is too long for insertion in 

 this place.
