arrow and the song

''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 frien
