BY broad Potomac's shore--again, old tongue! 
   (Still uttering--still ejaculating--canst never cease this babble?) 
   Again, old heart so gay--again to you, your sense, the full flush 
         spring returning; 
   Again the freshness and the odors--again Virginia's summer sky, 
         pellucid blue and silver, 
   Again the forenoon purple of the hills, 
   Again the deathless grass, so noiseless, soft and green, 
   Again the blood-red roses blooming. 
 
 
   Perfume this book of mine, O blood-red roses! 
   Lave subtly with your waters every line, Potomac! 
   Give me of you, O spring, before I close, to put between its 
         pages!                                                       10 
   O forenoon purple of the hills, before I close, of you! 
   O smiling earth--O summer sun, give me of you! 
   O deathless grass, of you!
Walt Whitman
