HELSINGLAND. 



further north in the same district, a kind 

 of blueish stone* is used for building the 

 tunnels or chimneys, which is considered 

 as more compact and better able to resist 

 heat than Lapis molaris or Vipsten (Cos 

 molaris ?). The limestone placed between 

 the other stones was procured from the sea 

 shore, and abounded with petrified corals. 



Granite, I believe of all the different 

 kinds existing in the world, abounds every 

 where in the forests. 



In every river a wheel is placed, con- 

 trived to lift up a hammer for the purpose 

 of bruising flax.
