Page 344 - Full many a gem of purest ray serene The dark unfathom'd caves of ocean bear : Full many a flower is born to blush unseen, And waste its sweetness on the desert air. Some village- Hampden, that, with dauntless breast, The little tyrant of his fields withstood, Some mute inglorious Milton here may rest, Some Cromwell guiltless of his country's blood. Th...
