BIRDS OF KANSAS. 91 



diameter by two and a half in depth. The borders of this inner 

 cup were lined with the down of the bird, in the same manner as 

 the Eider Duck's nest, and in it lay five eggs, 2.31x1.63; about 

 equally rounded at both ends, perfectly smooth, and of a pale 

 yellowish or cream color. ' ' The North American Water Birds ' ' 

 reports that Mr. MacFarlane found the birds breeding in con- 

 siderable numbers in the neighborhood of Fort Anderson, and 

 describes a nest, containing eight eggs, found June 25th, as 

 placed on a ridge of ground at the foot of a dry, stunted pine, 

 made of dark colored down, being entirely concealed from view 

 by the lower branches of the pine tree. All of the nests found 

 appear to have been of the same style and pattern, and nothing 

 is said of any other material than down being used in building 

 them. The number of eggs varied from five to eight, but the 

 latter number was found in only a single instance.
