andnotofpoliticaleconomy。
（3。xvii。10）Thereisnosubject，uponwhichthepolicyoftherestrictiveandprohibitive

whenitcanbeobtainedfromabroadwithasmallerquantityoflabourthanitcanbeproduced
withathome。Allthegood，therefore，whichisobtainedfromtheimportationofanycommodity，
capableofbeingproducedathome，isobtainedfromtheimportationofcorn。Whyshouldthat
advantagewhich，inthecaseofcorn，owingtothediversitiesofsoilandextentofpopulation，is
liabletobemuchgreaterthaninthecaseofanyothercommodity，bedeniedtothecommunity？
（3。xvii。11）Thereasons，uponwhichtheadvocatesforarestrictionofthecorntradechiefly

（3。xvii。12）Thefirstis，thatunlessthenationderiveitscornfromitsownsoil，itmay，bythe
enmityofitsneighbours，bedeprivedofitsforeignsupply，andreducedtothegreatestdistress。
Thisargumentimpliesanignorancebothofhistory，andofprinciple：Ofhistory，because，in

（3。xvii。13）Thesecondreason，uponwhichtheadvocatesofthecornmonopolysupport
themselves，is，that，ifthemerchantsandmanufacturersenjoyincertaincasesthemonopolyof

（3。xvii。14）Theargumentmoreoversupposes，thatanextraordinarygainisobtainedbythe

sustainedbythecorngrower，unlessheisfavouredbyasimilartax。Theignoranceofprinciple
ispeculiarlyvisibleinthosesuppositions，inneitherofwhichisthereashadowoftruth。
（3。xvii。15）Themanwhoembarkshiscapitalinthewoollen，oranyothermanufacture，with
the
produceofwhichthatoftheforeignmanufacturersisnotallowedtocomeintocompetition，
doesnot，onthataccount，deriveagreaterprofitfromhiscapital。Hisprofitisnogreaterthan

whichthatcommodity，ifimportedfromtheforeignmanufacturer，mightbebought。
（3。xvii。16）Asthemanwhohasembarkedhiscapitalinthetrade，whichiscalledprotected，
derivesnoadditionalprofitfromtheprotection；sothegrowerofcornsustainsnotanypeculiar
lossorinconvenience。Nothing，therefore，canbeconceivedmoregroundlessthanhisdemandof
acompensationonthataccount。Themarketforcornisnotdiminishedbecauseataxislaid

Hisbusiness，therefore，isnotintheleastdegreeaffectedbyit。
（3。xvii。17）Itwouldbeinconsistentwiththeplanofawork，confinedtotheexpositionof
general
principles，tolayopenallthefallacies，whichlurkintheargumentsforrestrainingthetradein
corn。Oneortwo，however，ofthesourcesofdeception，cannotbeleftaltogetherunnoticed。
（3。xvii。18）Thelandlordendeavourstorepresenthisowncase，andthatofthemanufacturer，
as
perfectlysimilar；though，inthecircumstanceswhichconcernthisargument，theyarenotonly
different，butopposite。Thelandlordalsoendeavourstomixuphisowncasewiththatofthe
farmer；anduponthesuccessofthatendeavouralmostalltheplausibilityofhispretensions
depends。Thatnopretensionsaremoreunfounded，maybeseenbyaveryshortprocessof
reasoning。Thefarmer，asaproducer，requires，likeeveryotherproducer，thatallhisoutgoings
bereturnedtohim，withthedueprofituponthecapitalwhichheemploys。Thesurplus，which
thelandyields，overandabovethisreturnandprofit，iswhathepaystohislandlord；andhis
interestisnotaffectedbythequantityofthatsurplus，whetheritbegreatorsmall。Hisinterest，
however，isverymuchaffectedbywages；because，inproportionaswagesarelow，hisprofits，
likeallotherprofits，arehigh。Wagescannotbelow，ifcornisdear。Theinterest，therefore，the
permanentinterest，oftheclassoffarmers，consists，inhavingcorncheap。Thisorthatindividual
intheclassmay，thatis，duringthecurrencyofalease，haveaninterestinhighprices；andthe
reasonoftheexceptionshowsthetruthofthegeneralrule。Theindividual，who，duringthe
currencyofalease，hasaninterestinhighprices，is，byhislease，converted，toacertainextent，
intoareceiverofrent。Duringthecontinuanceofhislease，ifpricesrise，hegets，notonlyhis
duereturnofprofitsasafarmer，butsomethingmore，namely，aportionofwhatistrulyrent，and
which，butforhislease，wouldhavegonetothelandlord。
（3。xvii。19）This，then，isthegranddistinction。Thereceiversofrentarebenefitedbyahigh
price
ofcorn；theproducersofcorn，assucharenotbenefitedbyit，butthereverse。Thecaseofthe
farmercorrespondswiththatofthemanufacturer，notwiththatofthelandlord。Thefarmerisa
producerandcapitalist；themanufacturerisaproducerandcapitalist；andtheyhaveboth
receivedallthatbelongstothem，whentheircapitalisreplacedwithitsprofits。Thelandlordis
notaproducer，noracapitalist。Heistheownerofcertainproductivepowersinthesoil；andall
whichthesoilproducesbelongstohim，afterpayingthecapitalwhichisnecessarytoputthose
productivepowersinoperation。Itthusappearsthatthecaseofthelandlordispeculiar；thata
highpriceofcornisprofitabletohim，because，thehighertheprice，thesmalleraportionofthe
producewillsufficetoreplace，withitsprofits，thecapitalofthefarmer；andalltherestbelongs
tohimself。Tothefarmer，however，andtoalltherestofthecommunity，itisanevil，bothasit

（3。xviii。2）Theonlypointofcolonialpolicy，whichitisherenecessarytoconsider，isthatof

fromit。
（3。xviii。3）Withrespecttocolonies，aswithrespecttoforeigncountries，thepropositionwill，
doubtless，beadmitted，that，whateveradvantageisderivedfromtradingwiththem，consistsin
whatisreceivedfromthem，notinwhatissent；becausethat，ifnotfollowedbyareturn，would
bealtogetherloss。
（3。xviii。4）Thereturnfromthemiseithermoneyorcommodities。Thereaderisbythistime
fully
awarethatacountryderivesnoadvantagefromreceivingmoney，morethanfromreceivingany
otherspeciesofcommodity。Itisalsoplainthatwherethecolonyhasnotminesoftheprecious

besideitsownproductions，tosend。
（3。xviii。5）Itisneedlesstoconsiderthecaseorfreetradewithacolony，becausethatfalls
under
thecaseortradewithanyforeigncountry。
（3。xviii。6）Themonopoly，whichamothercountrymayreservetoherself，ofthetradewith
her

（3。xviii。7）Firstofall，shemaytradewithhercolonies，bymeansofanexclusivecompany。
In
thiscase，thecolonyhasnopurchaser，towhomsheisallowedtosellanything，butthe
exclusivecompany；andnootherseller，fromwhomsheisallowedtobuyanything。The
company，therefore，canmakeherbuy，asdearasitpleases，thegoodswhichthemothercountry

otherwords，thecolonymay，inthesecircumstances，beobligedtogivefortheproduceofa

（3。xviii。8）Thecasesofatradeinthesecircumstancesaretwo：thefirst，wherethecolony
receivesfromthemothercountry，luxuries，comforts：theother，whereshereceivesnecessaries；
eitherthenecessariesoflife，orthenecessariesofindustry，asiron，&；c。
（3。xviii。9）Inthatcase，inwhichthecolonyreceivesluxuriesandcomfortsonlyfromthe

employthatgreatproportionofherlabour，inprovidingsuchluxuriesandcomfortsasshe

（3。xviii。10）If，however，thecolonyisdependantfornecessariesuponthemothercountry，
the
exclusivecompanyexercisesoverthecolonyapoweraltogetherdespotic。Itmaycompelherto

same。Shemaybemadetopayforthesearticlessomuchofthewholeproduceofherlabour，
thatnothingbutwhatisnecessarytokeepthepopulationalivemayremain。Itwouldbethe
interestofthemothercountry，nottolessenthepopulation；because，withthepopulation，the
producewouldbelessened，andhencethequantityofcommoditieswhichthemothercountry
couldreceive。
（3。xviii。11）Instead，however，oftradingwithhercoloniesbymeansofanexclusive
company，
themothercountrymayleavethetradeopentoallherownmerchants，onlyprohibitingthe
colonyfromtradingwiththemerchantsofanyothercountry。Inthiscase，thecompetitionofthe
merchantsinthemothercountryreducesthepriceofallthearticlesreceivedbythecolony，as
lowastheycanbeafforded—inotherwords，aslowasinthemothercountryitself，allowance
beingmadefortheexpenseofcarryingthem。Ifitbesaidthatthecoloniesaffordamarket；I
reply，thatthecapital，whichsuppliescommoditiesforthatmarket，wouldstillprepare
commodities，ifthecolonieswereannihilated；andthosecommoditieswouldstillfind
consumers。Thelabourandcapitalofacountrycannotpreparemorethanthecountrywillbe
willingtoconsume。Everyindividualhasadesiretoconsume，eitherproductivelyor
unproductively，whateverhereceives。Everycountry，therefore，containswithinitselfamarket
forallthatitcanproduce。Thiswillbemadestillmoreevident，whenthesubjectof

noadvantagewhatsoeverderived，underfreedomofcompetition，fromthatpartofthetradewith
acolonywhichconsistsinsupplyingitwithgoods，sincenomoreisgainedbyit，thansuch

neverthelesstruethatthecolonymaylosebysuchatraffic，ifthegoods，whichsheisthus

（3。xviii。12）Iftherebeanypeculiaradvantage，therefore，tothemothercountry，itmustbe
derivedfromthecheapnessofthegoods，withwhichthecolonysuppliesher。Itisevident，thatif

sinceshewouldhavetopayforthemashighasothercountries，ifthepeopleofthecolonywere
atlibertytosellwherevertheycouldobtainthegreatestprice。
（3。xviii。13）Thisadvantage，ifdrawnbythemothercountry，wouldbedrawnattheexpense
of
thecolony。Infreetrade，bothpartiesgain。Intheadvantageproducedbyforcing，whateveris
gainedbytheonepartyislostbytheother。Themothercountry，incompellingthecolonytosell

improvement，therefore，incolonialpolicywouldbe，tothrowopenthesupplyofthecolonies，

（4。iii。19）Theeffects，whichareproduced，inpractice，bythewantofadaptationintheparts
