To purify their wine some people bleed <br />A lamb into the barrel, and succeed; <br />No nostrum, planters say, is half so good <br />To make fine sugar, as a negro's blood. <br />Now lambs and negroes both are harmless things, <br />And thence perhaps this wondrous virtue springs. <br />'Tis in the blood of innocence alone-- <br />Good cause why planters never try their own.<br /><br />William Cowper<br /><br />http://www.poemhunter.com/poem/epigram-12/
