Joyant

Yon rippling stream, whose dimpled waves Leap sparkling by the shadowy graves, Singing a song as they leap along — A joyant song as they leap along — Makes the only sound that stirs the breeze, Is the only thing which the vision sees, Moving about 'neath the church-yard trees.

As roseal day agleam with glowing light, Bespeaks the impress of a joyant hand, So when I meet my love the day is bright: The undershadows topped with glory's strand, By great illuming of the somber night, To one who else would long in shadow stand.
