LAKES. 
Lakes of the district, their geological situation, etc.— Elevation and depression of water in 
the great lakes—Mean length, breadth, elevation and area of the several gi eat lakes 
Elevation of the smaller lakes—Elevation of different points in the district from Lake 
Ontario southward. 
The physical features of the district have already been alluded to at the commencement of 
the volume ; the principal valley of drainage is that of Lake Ontario, while the Susquehannah 
and the Allegany are the outlets of a part of the waters of the southern portion of the dis¬
