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 breadth a song into the air, It fell to earth, I knew not where; For who has the sight keen and strong, That it can follow the fight of song? Long, long afterwards 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. -H W Longfellow
