The far famed canvass-backs 



These celebrated and justly esteemed ducks, appear to 

 be the Jlnas Ferina of Lix. From the great abundancy 

 of their favorite food, (the roots of the Valiscneria A- 

 inericana.) in the tide waters of many of our large riv- 

 ers, it is probable that their flesh is much more delicious 

 here than in Europe.

But now the Lake 



The Seneca Lake. This beautiful sheet of water is 

 about forty miles long, by from one and a half to three 

 miles in breadth. The shores are generally precipitous, 

 consisting of a brittle blue slate, in which many curious 

 impressions of marine shells are perceivable. In a short 

 search I found upwards of twenty.
