For Dr Henry L Bowditch <br /> <br />With warning hand I mark Time's rapid <br />flight <br />From life's glad morning to it's solemn <br />night; <br />Yet through thee dear God's love, I also <br />show <br />There's Light above me by the shade <br />below.<br /><br />John Greenleaf Whittier<br /><br />http://www.poemhunter.com/poem/inscriptions-on-a-sun-dial/
