On tlie water, although the point hardly comes 

 vvitliin the scope of tliis work, the appearance of some 

 Ducks is worth noting, The Pintail, owing io his 

 slender build, long arching neck and raised tail, looks 

 more taking afloat than auy other species. The Gadwall 

 swims lightly, more so than the Mallard. The Mallard 

 on the water inclines his tail a rfood deal npivdrd^. 

 Both U,e Pochard and the Tufted Duck swim deep, tlie 

 former paiticularly so with an appearance of being down 

 at the stern. Something of the carriage of the birds on 

 the water may be gathered from the Plates in these 

 articles, in which are shown many of the species dealt 

 with in this book besides a few others that are not,

CHAPTER VII. 



Size. 



Size. (.Key 5.) 18, Size, or length (Col. 5, Key 1 and Key 5) is the 



distance from the tijj of tlie bill to the end of the longest 

 tail-feather. The size adopted is the vinximxnn given in 

 the Fauna, for it sometimes happens that the specimens 

 from which observations are there taken differ considerably, 

 e.ii., the length of the Pintail is given as 22 to 29 inches. 

 Most females are smaller in the Duck tribe than males. 

 Class C of Key 5, "Birds under IG Inches in Length" 

 includes, not only the Teal, but the White-eyed Duck, 

 which is only as large as the Garganey, This should not 

 lead the reader to believe that there is any generic aihnity, 

 between the White-eye, which is a Pochard, and the Teals 

 A'hich are True Ducks of small size (Seo Chapter V.)
