A single-page article from Scientific American (October 1860) describing R. J. Gatling's improved cotton cultivator, a horse-drawn machine that scrapes both sides of a cotton row and thins the plants in one pass. It explains how cotton rows are planted and worked, then details the mechanism: driving wheels, a cutter-head with four knives, adjustable scraper moldboards, and an india-rubber spring clutch that protects the shaft. An engraving shows the machine at work, and the article gives the patent date (July 3, 1860) and the inventor's address in Indianapolis.
