If those dark eyes have gazed on me, <br /> Unconscious of their power— <br />The glance in secret ecstasy <br /> I've treasured many an hour. <br />If that soft voice, a single word <br /> Has breathed for me to hear, <br />Like Heaven's entrancing airs, the chord <br /> Resounded on my ear. <br /> <br />And yet, alas! too well I knew <br /> That love—or hope—was vain, <br />The fountain whence delight I drew <br /> Would end in yielding pain! <br />My folly and my peace at once <br /> A moment could destroy; <br />It bade me every wish renounce, <br /> And broke my dream of joy<br /><br />Louisa Stuart Costello<br /><br />http://www.poemhunter.com/poem/song-if-those-dark-eyes/
