about the village for nearly two weeks; on June 4th, while standing 
on Black Bluff, St. Paul, I watched a swallow coming in to the 
land and then fly northward up the island; I foundanest at Una- | 
laska, on August 13th, containing three large young, a male and 
two females, and secured the adults also; the nest is of mud 
held together by grass rootlets ; it is g inches wide by 4 inches 
deep, the cavity is 2% inches in diameter and 134 inches deep ; 
grass rootlets encircle the cavity, which is well lined with gull and 
raven feathers; it was built in a large cavity, almost a cave, of a 
rock on a hillside, and was placed on the slightly sloping face of 
the back portion, about its centre; a slight inequality of the rock 
face was sufficient to hold it in place; to enter the cavity the 
birds had to fly to the face of the rock and then dip downward 
between the rock and many tall plants, which effectually hid the 
opening; I saw no others. (/Palmer.)
