DESCRIPTIONES LUCANIDARUM, &C. 259 



While stars, her wakeful watchmen, keep 

 Their vigils o'er a world asleep ; 

 Till, struggling with the morn, their strife 

 Awakes earth up to love and life. 



Thus love rules all : it is the heart 

 Whence all the streams of life depart ; 

 The never-failing fountain-head, 

 From which all other springs are fed. 



The universe contains no place 

 That has been left without its grace ; 

 And beauty 's o'er the picture laid 

 In countless tints of light and shade. 



I'll never, Nature, bid farewell 

 To thee ; thou in my brain shalt dwell, 

 Till mind shall have outgrown its clay, 

 And left its garment to decay.
