I short an Arrow

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 it's 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 unbroken;
And the song, from beginning to end,
I found again in the heart of a friend.
