tnrns to the warmer parts of tlie continent. In its migratory course, 

 it is frccjuently met with in the Midflle Atlantic Districts, and is quite 

 common on the Chesapeake Bay tluring- winter. Two species arc 

 known to inliabit this continent — tlie present, [Cygnns Amcricanus,] 

 and the Trumpeter Swan, [Cysfnus Barinator.] The latter differs 

 from the former by being- superior in size, as well as in its anatomi- 

 cal structure, 'i'hcse species we"e separated by Mr. Sharjjless, who 

 decided this point from his knowledg-e of comparative anatomy. 



This elegant bird is frer|uently domesticated, and by its spotless 

 pkimag-e, and graceful movem?nts when on ils native element, fails 

 not to attract the afteniicn cf tlie pcsser Ly. The young are highly 

 esteemed for the table. 



The pre^^.^nt species is the only one which I have ever known to 

 be seen in this vicinity.
