GLACIAL PHENOMENA IN MAINE. 123 
ing edgewise, in a vertical position, and strik¬ 
ing east-northeast. Scratches, grooves, and 
fur rows of every dimension, sometimes very 
distinct, sometimes fainter, but always recti¬ 
linear and always running due north, traverse 
the edges of these beds at right angles with the 
surfaces of stratification and the trend of the 
beds. It is evident that here there can be no 
confounding of the glacial marks with struc¬ 
tural lines, or cracks in the strata, — for these 
would not run at right angles with the struc¬ 
ture of the rock itself; or with furrows made 
by water, — for these would have followed the 
strata instead of crossing them; or with any 
displacement of the beds moving upon one 
another, — a suggestion which has sometimes 
been made to explain the appearance of these 
marks upon horizontal surfaces. Nor is there 
any trace of the angular ledges which must 
have resulted from the tilting of these strati¬ 
fied rocks. The whole region is levelled and 
smoothed down to an undulating plain. 
While investigating the facts in this locality, 
I could not but recall the criticism of the 
“ greatest geologist of the age ” * upon the gla- 
* Leopold von Buch.
