CHAPTER XXXI 

 ORDER OF DUCKS, GEESE, AND SWANS 



ANSERES 



WE have now reached the first Order of a great group of 

 birds which might well stand as a Subclass — the Web- 

 Footed Swimmers. It embraces six different Orders, and be- 

 fore touching any one of them it is highly necessary that the 

 student should take a bird's-eye view of the whole subdivision. 

 A clear conception of these six Orders, and the characters on 

 which they are based, will be of perpetual service to every 

 person who desires a comprehensive view of the avian world.
