In Pitts *rippling cylinder were combined the first use ofthe circular motion, the first forerunner of the reel, and thefirst utilization of the principle involved in transmitting powerfrom the wheels of the machine to operate some of its latter principle has been utilized in practically all harvest-ing machines ever built, excepting some of the combined har-vesters constructed since 1903. Some form of the reel is alsofound on every harvesting machine which has had any consideration of these facts, Pitts name holds high rankamong inventors of harvesting machinery. The first patent on a reaping machine was granted in Eng-land to Joseph Boyce in 1799. Its only title to fame is AN EARLY ENGLISH REAPER INVENTED BY BELL, 1828 A year later an unsuccessful attempt was made to adopt shearsas a cutting apparatus. This machine was unique in beingoperated by human power. Outside and inside dividers toseparate the swath from the grain left standing, now foundon all harvesting machines, were apparently first used in Gladstones machine (1806), the fiist to be drawn insteadof pushed, appeared the side cut and the platform upon whichthe severed grain falls. Salmon (1808) first utilized the re-ciprocating cutter combined with the advancing motion of themachine. His reaper was also the first to have a self-deliveringapparatus for the giain. Dobbs, a theatrical genius, inventeda reaper (1841) and introduced it to the public in a play adapt- 86 THE BOOK OF WHEAT ed to this purpose. The stage was planted with wheat whichwas harvested by the machine during the course of the
