birds found at Como Lake, Wyoming. He says: "The nests were in a 

 narrow strip of rushes growing in water eighteen inches deep, and 

 \ \ about one hundred and thirty feet from the shore. * * * * 

 I collected the eggs from two nests, five in each; and counted from 

 ^here I stood over twenty nests with from one to five eggs each. Quite 

 A number of others were completed, but without eggs, and still others 

 were building. The floating nests were made of old broken rushes, 

 weeds and debris from the bottom, and were partially filled in and 

 around the standing, growing rushes. There were no feathers or other 

 kild of lining. They were from five to ten inches in diameter; the 

 outer edge or rim was from two to three inches above the water. The 

 eggs in several touched the water, and were more or less stained in 

 their wet beds. The coloT of the eggs when fresh was white, with a 

 slight bluish shade. The average measurements of the ten eggs was 

 1.81 by 1.20 inches." The same careful observer notes that in leaving 

 their nests the birds would dive and come up quite a distance away out 

 in the open lake and, when returning to their nests, would dive out in 

 the lake and come up among the rushes. He says in no instance did 

 he see them swim to or from their nests, but adds, they may do so. 

 when not disturbed.
