those which were exposed. I mention this incident to give an idea 

 of the adhesiveness of the gkie used in the construction of Swifts' 

 nests. 



July 20 I made the following note: ''Swiftlings no longer 

 make use of the nest, but dispose themselves in various parts of the 

 chimney, sometimes in a cluster, sometimes in twos or threes, and 

 sometimes separately. They take flying exercises up and down the 

 chimney, but I believe have not yet left it." The next morning I was 

 forced to conclude that three had taken flight into the great outside 

 world, for upon looking the chimney over thorough!}- with the aid of 

 a small mirror, I could find but two birds.

 Swifts were seen gathering in a flock at a short distance from the 

 house. Ten o'clock that night I searched the chimney with a 

 lighted candle, but found no sign of life, and I believe that the 

 Swifts did not again enter within its walls.

curiously shaped orange bill, which is almost as thin as a knife, the 



thin edges closing vertically together. This peculiarity has given 



the bird the name of • Raiior Bill.' 



Their graceful and regular flight can hardly be mistaken for that 

 of any other bird. They skim just over the surface of the water, 

 following the contour of the waves, while the lower mandible of their
