GLACIAL PHENOMENA IN MAINE.

Calais and over the whole track from Calais to 
East-port, numerous polished surfaces are visi¬ 
ble, with distinct scratches and furrows point¬ 
ing due north. I may say, therefore, from my 
own personal observation, that the State of 
Maine, for nearly its whole width, that is, 
over four degrees of longitude, and between 
latitude 44° and 45°, bears all the characteris¬ 
tic indications of glacial action on its surface. 
But while many of these phenomena are per¬ 
fectly simple and clear to one intimately ac¬ 
quainted with the effects produced by moving 
masses of ice, I have noticed near Bangor, and 
more especially in the neighborhood of Water- 
ville, facts not so readily explained, though 
I believe I have found their true solution. 
Ordinarily all the glacial marks in a given 
locality run in one direction, and have cer¬ 
tainly been produced simultaneously by one 
and the same agent, however opinions may 
differ as to the nature of that agent. But on 
Ledge Hill, five and a half miles from Bangor, 
faint striae may be seen pointing due north, 
while upon the same slab are other lines point¬ 
ing northwest, forming an angle of forty-live 
decrees with the first. I believe that here
