there are similar boulder phenomena to those observed fort 
miles west among the Camden hills. These mountains wh 
amid these vast ruins, it is apparent that only the irresistible 
grasp of a glacier could have broken them off and carried them 
far away toward the south. Here, as elsewhere, the granitic 
boulders are larger and less angular as we approach the hills 
from the south. Among these boulders, rocks of other forma- 
tions are rarely found; and these are from the slates to the north 
of the hills, having been carried over these elevations, not around 
them. Upon the northern declivities of these hills, the boulders 
are not so numerous nor so large as they are on the south, but are 
generally much worn; and like those on the south, they are 
syenitic, like the formation of the hills, 
ut besides the coves and harbors of this great island of Mount 
Desert, its ledges, headlands and ponds, (some of which last are 
large and deep,) all trend north and south in conformity to the 
course of the striz. More than one of its deeper ponds are 
gouged out of the solid syenite, and we find no evidence of this 
having been done by any other agency than that of glaciers. 
Beyond these hills to the north, for fifteen or twenty miles, 
over a comparatively level country, the Taconic slates again ap 
pear; and the detritus of these rocks have been but sparingly 
transported over the granitic formation of Mount Desert. I thi 
it a safe conclusion that the rocks torn from the hills, the valleys 
and the plains of the country, were not generally removed to any 
great distance southward. We find indeed the fossiliferous rocks 
rom the region beyond Katahdin, a hundred and fifty miles 
north, scattered over the islands of the coast; brought doa 
upon the more elevated parts of the glacier, rather than attache 
to or near its under surface, during their distant transportaon 
But these rocks are by no means abundant. :
