will weigh, when fattened for market, from sixteen to twenty 

 pounds a pair. 



The Rouens (see illustration, page 1104) are marked almost 

 exactly like the wild Mallards; in fact, they are the wild Mal- 

 lards domesticated and improved. In size and useful qualities 

 they rank next to the Pekins. 



AYLESBUBY DUCKS. 



The Aylesburys (see illustration, this page) do not often 

 grow so large as the Pekins, but in other respects they rank 

 about the same. 



Concerning the Black Cayugas (see illustration, page 1106), 

 a variety not so well known as those already mentioned, the 

 " Complete Poultry Book " has the following : 



" This fine breed is American, and is supposed to have orig- 

 inated in the neighborhood of Cayuga Lake, New York, by a 

 cross between the wild black, or Buenos Ayres duck, and the 

 wild Mallard. The markings of the Cayuga duck are black 

 throughout, except a narrow white collar around the neck, and 

 white flecks on the breast, which latter tend to increase with 

 age, and are avoided by breeders as much as possible. Both 



ducks and drakes show a greenish tinge about the head.
