AUDUBON AND BOONE. 185 



deliglit which it gave me. Not even Herschel, when he dis- 

 covered the planet which bears his name, could have expe- 

 rienced more rapturous feelings. We were on a trading 

 voyage, ascending the Upper Mississippi. The keen wintry 

 blasts whistled around us, and the cold from which I suffered 

 had, in a great degree, extinguished the deep interest which, 

 at other seasons, this magnificent river has been wont to 

 awake in me. I lay stretched beside our patroon. The 

 safety of the cargo was forgotten, and the only thing that 

 called my attention was the multitude of ducks, of different

 and snatch them up in the manner of the Fishing Hawk; 

 and that they roosted generally on the shelves of the rocks,

 several by the quantity of white dung scattered below. 



Convinced that the bird was unknown to naturalists, I felt 

 particularly anxious to learn its habits, and to discover in 

 what particulars it differed from the rest of its genus. My 

 next meeting with this bird was a few years afterwards, whilst 

 engaged in collecting crayfish on one of those flats which 

 border and divide Green River, in Kentucky, near its junc-
