Sweet stream that winds through yonder glade, <br />Apt emblem of a virtuous maid <br />Silent and chaste she steals along, <br />Far from the world's gay busy throng: <br />With gentle yet prevailing force, <br />Intent upon her destined course; <br />Graceful and useful all she does, <br />Blessing and blest where'er she goes; <br />Pure-bosom'd as that watery glass, <br />And Heaven reflected in her face.<br /><br />William Cowper<br /><br />http://www.poemhunter.com/poem/a-comparison-addressed-to-a-young-lady/
