extended mapping of the old shores and in determinations of tiieir alti- 
tudes and changes of level. Traces of other ice-dammed lakes have 
been also carefnlly studied in New Hampshire, New Jersey, New York, 
the Ohio valley, and the Soiiris valley in North Dakota and Manitoba. 
Such lakes are also recorded by the Parall«l Roads of Glen Roy, and by 
high beach lines in the valleys on the east side of the Scandinavian 
mountains. No marine fossils occur in the beaches or other contempo- 
raneous deposits; but fresh-water molluscan shells are found in these 
deposits within the area of lake Agassiz, which occuiDied the basin of 
the Red river and of the Manitoba lakes, and in the beaches and deltas 
of lakes Warren, Algonquin and Iroquois. These bodies of water are 
thus proved to have been lacustrine; and the differential inclinations of 
their shores demonstrate that no land barriers, but onl}' the receding 
ice, could have confined them on their north and northeast sides.
