THE GREAT LAKE BASINS OF THE St. LAWRENCE. 
By A. T. Drummonp. 
When recently considering the physical and geological 
relations of tue Canadian flora, my attention was drawn to 
the many interesting questions connected with the forma- 
tion of the St. Lawrence Great Lake Basins. What had 
been their history in past time? Were these lakes, as has 
been so long maintained, the outcome of the forces of the 
glacial age, or had they not in some cases an antecedent, 
and in others, or all, a subsequent history as well? What 
influences had they exercised on the climate, fauna and 
flora of the north-eastern part of the continent in the past ? 
How far do their present contours and depths, the physical 
Avutnor’s Nore.—Since this paper was written, I have seen the 
very brief abstracts of articles on a similar subject by Prof. Spencer, 
which have been pnblished in the Recorp or Somnon for October, 
issued this month. I am glad to find that his views on one or two 
points referred to in this paper confirm the conclusions I had ar- 
rived at independently.
