134 THE SONG SPARROW. 



parlor-organ. All these vocal contrivances are greatly 

 aided again by the air-cavities and passages pervading the 

 interior of the body, the muscles and the bones. The 

 delightful qualities of tone, and the variations of melody 

 which are thus made possible to the sylvan songster, must 

 fall on the ear of a genuine lover of music to be fully 

 appreciated. Truly nature has concentrated the energy of 

 the song-bird in the vocal powers as well as that of birds in

 lessly varied. Well, indeed, has this interesting species 

 been called the Song Sparrow. 



In autumn, even, especially in the balmy days of Indian 

 Summer, one may hear its lay not so loud and penetrat-
