The Arrow and the Song, Henry Wadsworth Longfellow

I shot an arrow into the air, 

It fell to earth, I knew not where; 

For, so swiftly it flew, the sight 

Could not follow it in its flight. 

I breathed a song into the air, 

It fell to earth, I knew not where; 

For who has sight so keen and strong, 

That it can follow the flight of song? 

Long, long afterward, in an oak 

I found the arrow, still unbroke; 

And the song, from beginning to end, 

I found again in the heart of a friend.
