I shot an arrow into the air, <br />It fell to earth, I knew not where; <br />For, so swiftly it flew, the sight <br />Could not follow it in its flight. <br /> <br />I breathed a song into the air, <br />It fell to earth, I knew not where; <br />For who has sight so keen and strong, <br />That it can follow the flight of song? <br /> <br />Long, long afterward, in an oak <br />I found the arrow, still unbroke; <br />And the song, from beginning to end, <br />I found again in the heart of a friend.<br /><br />Henry Wadsworth Longfellow<br /><br />http://www.poemhunter.com/poem/the-arrow-and-the-song/
