easier；　and　gave　him　great　control。　Such　ploughs　were　certainly　in　use　as　early　as　1844；　perhaps　earlier。　The　next　step　forward　was　to　substitute　for　horses　a　traction　engine。　Today　one　may　see　on　thousands　of　farms　a　tractor　pulling　six；　eight；　ten；　or　more　ploughs；　doing　the　work　better　than　it　could　be　done　by　an　individual　ploughman。　On　the　〃Bonanza〃　farms　of　the　West　a　fifty　horsepower　engine　draws　sixteen　ploughs；　followed　by　harrows　and　a　grain　drill；　and　performs　the　three　operations　of　ploughing；　harrowing；　and　planting　at　the　same　time　and　covers　fifty　acres　or　more　in　a　day。

The　basic　ideas　in　drills　for　small　grains　were　successfully　developed　in　Great　Britain；　and　many　British　drills　were　sold　in　the　United　States　before　one　was　manufactured　here。　American　manufacture　of　these　drills　began　about　1840。　Planters　for　corn　came　somewhat　later。　Machines　to　plant　wheat　successfully　were　unsuited　to　corn；　which　must　be　planted　less　profusely　than　wheat。

The　American　pioneers　had　only　a　sickle　or　a　scythe　with　which　to　cut　their　grain。　The　addition　to　the　scythe　of　wooden　fingers；　against　which　the　grain　might　lie　until　the　end　of　the　swing；　was　a　natural　step；　and　seems　to　have　been　taken　quite　independently　in　several　places；　perhaps　as　early　as　1803。　Grain　cradles　are　still　used　in　hilly　regions　and　in　those　parts　of　the　country　where　little　grain　is　grown。

The　first　attempts　to　build　a　machine　to　cut　grain　were　made　in　England　and　Scotland；　several　of　them　in　the　eighteenth　century；　and　in　1822　Henry　Ogle；　a　schoolmaster　in　Rennington；　made　a　mechanical　reaper；　but　the　opposition　of　the　laborers　of　the　vicinity；　who　feared　loss　of　employment；　prevented　further　development。　In　1826；　Patrick　Bell；　a　young　Scotch　student；　afterward　a　Presbyterian　minister；　who　had　been　moved　by　the　fatigue　of　the　harvesters　upon　his　father's　farm　in　Argyllshire；　made　an　attempt　to　lighten　their　labor。　His　reaper　was　pushed　by　horses；　a　reel　brought　the　grain　against　blades　which　opened　and　closed　like　scissors；　and　a　traveling　canvas　apron　deposited　the　grain　at　one　side。　The　inventor　received　a　prize　from　the　Highland　and　Agricultural　Society　of　Edinburgh；　and　pictures　and　full　descriptions　of　his　invention　were　published。　Several　models　of　this　reaper　were　built　in　Great　Britain；　and　it　is　said　that　four　came　to　the　United　States；　however　this　may　be；　Bell's　machine　was　never　generally　adopted。

Soon　afterward　three　men　patented　reapers　in　the　United　States：　William　Manning；　Plainfield；　New　Jersey；　1831；　Obed　Hussey；　Cincinnati；　Ohio；　1833；　and　Cyrus　Hall　McCormick；　Staunton；　Virginia；　1834。　Just　how　much　they　owed　to　Patrick　Bell　cannot　be　known；　but　it　is　probable　that　all　had　heard　of　his　design　if　they　had　not　seen　his　drawings　or　the　machine　itself。　The　first　of　these　inventors；　Manning　of　New　Jersey；　drops　out　of　the　story；　for　it　is　not　known　whether　he　ever　made　a　machine　other　than　his　model。　More　persistent　was　Obed　Hussey　of　Cincinnati；　who　soon　moved　to　Baltimore　to　fight　out　the　issue　with　McCormick。　Hussey　was　an　excellent　mechanic。　He　patented　several　improvements　to　his　machine　and　received　high　praise　for　the　efficiency　of　the　work。　But　he　was　soon　outstripped　in　the　race　because　he　was　weak　in　the　essential　qualities　which　made　McCormick　the　greatest　figure　in　the　world　of　agricultural　machinery。　McCormick　was　more　than　a　mechanic；　he　was　a　man　of　vision；　and　he　had　the　enthusiasm　of　a　crusader　and　superb　genius　for　business　organization　and　advertisement。　His　story　has　been　told　in　another　volume　of　this　series。*

Though　McCormick　offered　reapers　for　sale　in　1834；　he　seems　to　have　sold　none　in　that　year；　nor　any　for　six　years　afterwards。　He　sold　two　in　1840；　seven　in　1842；　fifty　in　1844。　The　machine　was　not　really　adapted　to　the　hills　of　the　Valley　of　Virginia；　and　farmers　hesitated　to　buy　a　contrivance　which　needed　the　attention　of　a　skilled　mechanic。　McCormick　made　a　trip　through　the　Middle　West。　In　the　rolling　prairies；　mile　after　mile　of　rich　soil　without　a　tree　or　a　stone；　he　saw　his　future　dominion。　Hussey　had　moved　East。　McCormick　did　the　opposite；　he　moved　West；　to　Chicago；　in　1847。

Chicago　was　then　a　town　of　hardly　ten　thousand；　but　McCormick　foresaw　its　future；　built　a　factory　there；　and　manufactured　five　hundred　machines　for　the　harvest　of　1848。　From　this　time　he　went　on　from　triumph　to　triumph。　He　formulated　an　elaborate　business　system。　His　machines　were　to　be　sold　at　a　fixed　price；　payable　in　installments　if　desired；　with　a　guarantee　of　satisfaction。　He　set　up　a　system　of　agencies　to　give　instruction　or　to　supply　spare　parts。　Advertising；　chiefly　by　exhibitions　and　contests　at　fairs　and　other　public　gatherings；　was　another　item　of　his　programme。　All　would　have　failed；　of　course；　if　he　had　not　built　good　machines；　but　he　did　build　good　machines；　and　was　not　daunted　by　the　Government's　refusal　in　1848　to　renew　his　original　patent。　He　decided　to　make　profits　as　a　manufacturer　rather　than　accept　royalties　as　an　inventor。

McCormick　had　many　competitors；　and　some　of　them　were　in　the　field　with　improved　devices　ahead　of　him；　but　he　always　held　his　own；　either　by　buying　up　the　patent　for　a　real　improvement；　or　else　by　requiring　his　staff　to　invent　something　to　do　the　same　work。　Numerous　new　devices　to　improve　the　harvester　were　patented；　but　the　most　important　was　an　automatic　attachment　to　bind　the　sheaves　with　wire。　This　was　patented　in　1872；　and　McCormick　soon　made　it　his　own。　The　harvester　seemed　complete。　One　man　drove　the　team；　and　the　machine　cut　the　grain；　bound　it　in　sheaves；　and　deposited　them　upon　the　ground。

Presently；　however；　complaints　were　heard　of　the　wire　tie。　When　the　wheat　was　threshed；　bits　of　wire　got　into　the　straw；　and　were　swallowed　by　the　cattle；　or　else　the　bits　of　metal　got　among　the　wheat　itself　and　gave　out　sparks　in　grinding；　setting　some　mills　on　fire。　Two　inventors；　almost　simultaneously；　produced　the　remedy。　Marquis　L。　Gorham；　working　for　McCormick；　and　John　F。　Appleby；　whose　invention　was　purchased　by　William　Deering；　one　of　McCormick's　chief　competitors；　invented　binders　which　used　twine。　By　1880　the　self…binding　harvester　was　complete。　No　distinctive　improvement　has　been　made　since；　except　to　add　strength　and　simplification。　The　machine　now　needed　the　services　of　only　two　men；　one　to　drive　and　the　other　to　shock　the　bundles；　and　could　reap　twenty　acres　or　more　a　day；　tie　the　grain　into　bundles　of　uniform　size；　and　dump　them　in　piles　of　five　ready　to　be　shocked。

Grain　must　be　separated　from　the　straw　and　chaff。　The　Biblical　threshing　floor；　on　which　oxen　or　horses　trampled　out　the　grain；　was　still　common　in　Washington's　time；　though　it　had　been　largely　succeeded　by　the　flail。　In　Great　Britain　several　threshing　machines　were　devised　in　the　eighteenth　century；　but　none　was　particularly　successful。　They　were　stationary；　and　it　was　necessary　to　bring　the　sheaves　to　them。　The　seventh　patent　issued　by　the　United　States；　to　Samuel　Mulliken　of　Philadelphia；　was　for　a　threshing　machine。　The　portable　horse…power　treadmill；　invented　in　1830　by　Hiram　A。　and　John　A。　Pitts　of　Winthrop；　Maine；　was　presently　coupled　with　a　thresher；　or　〃separator；〃　and　this　outfit；　with　its　men　and　horses；　moving　from　farm　to　farm；　soon　became　an　autumn　feature　of　every　neighborhood。　The　treadmill　was　later　on　succeededby　the　traction　engine；　and　the　apparatus　now　in　common　use　is　an　engine　which　draws　the　greatly　improved　threshing　machine　from　farm　to　farm；　and　when　the　destination　is　reached；　furnishes　the　power　to　drive　the　thresher。　Many　of　these　engines　are　adapted　to　the　use　of　straw　as　fuel。

Another　development　was　the　combination　harvester　and　thresher　used　on　the　larger　farms　of　the　West。　This　machine　does　not　cut　the　wheat　close　to　the　ground；　but　the　cutter…bar；　over　twenty…five　feet　in　length；　takes　off　the　heads。　The　wheat　is　separated　from　the　chaff　and　automatically　weighed　into　sacks；　which　are　dumped　as　fast　as　two　expert　sewers　can　work。　The　motive　power　is　a　traction　engine　or　else　twenty　to　thirty　horses；　and　seventy…five　acres　a　day　can　be　reaped　and　threshed。　Often　another　tractor　pulling　a　dozen　wagons　follow
