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 found a nest 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 9 inches wide by 4 inches 

 deep, the cavity is 2J^ inches in diameter and 1% inches deep ; 

 gfass 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.)
