BIRDS OF THE AIR. 253 



from immemorial time has protected it. The aboriginal 

 inhabitants set hollowed gourds upon the trees to draw 

 the Martins to their huts. And when the white man 

 came, he provided them with a meeting-house, consider- 

 ing it a fitting structure for their musical congregations. 



The Purple Martin utters a series of notes which are 

 so varied and continued as to deserve to be called a song. 

 This song has attracted less attention from those who 

 have described the habits of our birds than it merits. 

 In my early days I have listened for hours to the peculiar 

 notes of the Purple Martin, in which a variety of chatter- 

 ing and chuckling is combined with a low guttural trill,

 constitute his prey at so great a height. 



The boldness displayed by the Purple Martin in driving 

 Hawks and Crows from his neighborhood accounts for the 

 respect in which he was held by the Indians, who were 

 great admirers of courage. " So well known," says A\ il-
