     There‘s much in a name. The reputation of the C'aurasback‘ among 
     
     gom-nwnds, is too firmly established to be questioned; but, given the 
     
     same chef. and half a dozen of our Ducks can be made to do duty for 
     
     this favorite of epieures. In some parts of the west, where folks have 
     
     a way of thinkingr for themselves, the (.‘anvasbaek is frankly placed 
     
     second to his cousin the Redh ‘Eld. 
     
    

    
     The (‘anvasback is at its best when the bird has been for sometime 
     
     feeding,r on wild celery—a diet which equally improves the flesh of 
     
     other species.
