SUPPLEMENT. 661 
from the banks. On the 15th of June, the day on which the ice on the river broke 
up, several clutches of eggs were brought to him, all somewhat incubated, and the 
last four clutches, taken by himself on the 26th, would have been hatched in a few 
days. This Gull nested in little companies of from two or three to ten or fifteen 
pairs, making its nest in wet grassy spots near the water, and the nests rose from 
four to ten inches above the surface. The hollow formed in the grass—dead grass, 
as green grass is hardly seen even by the 20th of June—is about six or seven inches 
in diameter, but the nest proper is a shallow cup only about four or four and a half 
inches in diameter. It is composed of dry grass and Carices, sometimes with the 
addition of a few dry Betula or Salia leaves, while one was made of white 
Reindeer-moss. Three dozen eggs were procured, and those that I have seen are 
indistinguishable from those of Larus sabinii; but Mr. Buturlin has since sent skins 
of L. roseus to Mr. Dresser in confirmation of the eggs.

were on the ground, and made of hay, feathers, and down, while six was the usual 
number of the eggs. The exceptional case was a ne t in the fork of a tree some 
nine fe from the ground.
