 the setting sun illuminating the glorious peaks of the hill-tops, 

 and throwing into shade the depths lying below my feet. I 

 was conscious of an occasional buzz of wings past my face, 

 and soon discovered that the roof of the Dak JJungalow was 

 tenanted by a colony of the small Indian Swift {Micropus

 can easily be applied. 



In addition to the characteristic rapidity of their flight, the 

 Swifts further differ from the Swallows, with which they have 

 been associated by so many writers, in having only ten tail-
