The Arrow and the Song lyrics

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 breath'd 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 a 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
