"Elevation and depression of water in the Great Lakes. 
For numerous interesting facts in relation to this subject, see an article in the 16th volume of Silliman’s 
Journal, by Gen. H. A. S. Dearborn. 
See also a pamphlet on the same subject by Edward Giddings, of Lockport.

Salines. 
In the course of this Report, several unimportant salines were mentioned as occurring in the higher 
groups of the system. One of these was at Jefferson, and another near Big-stream point. As they ap¬ 
peared to offer no inducements for further exploration, they have merely received the attention which was 
considered due to them. Since this Report has passed through the press, I have learned that salt in con¬ 
siderable quantity has been made from a similar spring in Dundee, Yates county. Not having visited 
the place, I am unable to say what probability there is of a supply of brine; and in the absence of any 
definite, information on the subject, this notice is all that can be given.

necessary, a separate report on the subject being in preparation.
