80 CHARACTERS OF SIALIA MEXICANA 



song is melody without great power ; delightful modulation 

 without exhibition of the highest art : it is sweet and charming, 

 lacking great force, yet with a touch of such nervous quality 

 that more is left to the imaginatiou than is revealed. Like the 

 sunshine of the days when the year is young, and nature seems 

 to pause to gather strength for her intended triumphs, this melt- 

 ing music of the Bluebird is full of delicious languor and dreamy 

 voluptuousness, suggesting the possibilities of all things, ex- 

 pressing the realities of none. It is a promise and a pledge of 

 the future, like the unconscious yearning of a maiden for what 

 she knows not.
