                Under the wide and starry sky,
                    Dig the grave and let me lie.
                Glad did I live and gladly die,
                    And I laid me down with a will.

                This be the verse you grave for me:
                    Here he lies where he longed to be;
                Home is the sailor, home from sea,
                    And the hunter home from the hill.

                My Heart Leaps Up

            @output
                My heart leaps up when I behold 
                    A rainbow in the sky:
                So was it when my life began; 
                So is it now I am a man; 
                So be it when I shall grow old, 
                    Or let me die!
                The Child is father of the Man;
                And I could wish my days to be
                Bound each to each by natural piety.
