CHAP. IV.] THE GIANT S GRAVE. 65 



there is a long superficial ridge of gravel, sand, and boulders, 

 having the same appearance as those mounds which are termed 

 &quot; osar&quot; in Sweden. It is a conspicuous object on the plain, and. 

 is called the Giant s Grave ; but in general such geological ap 

 pearances as are usually referred to the glacial or &quot; drift&quot; period 

 are rare in these mountains ; and I looked in vain for glacial 

 furrows and striae on a broad surface of smooth granite recently 

 exposed on the banks of the Saco, in a pit where gravel had been 

 taken out for the repair of the road. How far the rapid decom 

 position of the granite rocks, owing to the vast range of annual 

 temperature, may have destroyed, in this high region, any mark 

 ings originally imprinted on their surface, deserves consideration.
