GLACIERS IN THE WHITE MOUNTAINS, 283 
traced over so wide an area, there have been what may 
be termed local glaciers,—masses of ice which belonged 
especially to certain mountain groups, and moved down the 
large valleys, leaving marks upon the rocks over which they 
passed, according in direction with the course of the valleys, 
and varying widely from that of the prevailing north and 
south traces. 
The White Mountains of New Hampshire, both from their 
height and their northern latitude, give us reason to suppose 
that if local glaciers ever existed in New England, their 
traces would be found in the valleys of this group. The 
late Dr. Edward Hitchcock ‘predicted that such would be the 
ease. Dr. A. S. Packard, of Salem, after an examination 
of the eastern slope of the White Mountains, concluded. that 
glaciers had, during some former period, radiated from the 
higher summits. The reader is particularly referred to his 
article in the first volume of this Magazine, as the glacial 
traces there referred to are laid down upon the map accom- 
panying this paper, and as a section of the mountains but 
little known is there described. 
It is to a part of the Androscoggin Valley, and to the 
Upper part of its tributary, the Peabody River, that attention 
Ws here called, as facts plainly seen upon the ground seem to 
show that a glacier moved from Mount Washington down to 
the point where Gorham now stands, and that it joined at 
that place another large glacier, moving down the Andros- 
Coggin almost twenty miles, to Bethel. 
he general course of the Androscoggin River, from its 
source to its mouth, is south-east; but this general course 
'S made up of local courses which differ widely in direction. 
rom its junction with the Megalloway, west of Umbagog 
Lake, to Gorham, thirty miles, it flows from north to south ; 
‘om Gorham to Bethel, twenty miles, it flows from west to 
“ast; at Bethel it turns abruptly round and flows for six 
miles north, and from the point thus reached east for thirty 
“8, but with great local variations ; thence thirty miles
