an inventor. He made a steamboat and improved the cotton gin. Longstreet patented a valuable improvement in cotton gins, called the “breast roller,” moved by horse power, which entirely superseded the old method. He set up two of his gins in Augusta, which were propelled by steam and worked admirably; but they were destroyed by fire within a week. He next erected a set of steam mills near St. Mary's, Georgia, which were destroyed by the British in 1812.
