And feels in hope the raptures'of the day — 



Eager he looks : and soon, to glad liis eyes, 



From the sweet bower, by nature form- d, arise 



Bright trooiis of virgin nioths and fresh-born butterflies; 



Who liroke that morning from their half-year's sleep.

C'KABBE. 



Mine eye and heart are at a mortal war 

 How to divide the conquest of thy sight.
