CHAPTERII
OfMoneyconsideredasaparticularBranchofthegeneralStockoftheSociety，oroftheExpenseofmaintainingtheNationalCapitalIThasbeenshowninthefirstbook，thatthepriceofthegreaterpartofcommoditiesresolvesitselfintothreeparts，ofwhichonepaysthewagesofthelabour，anothertheprofitsofthestock，andathirdtherentofthelandwhichhadbeenemployedinproducingandbringingthemtomarket:thatthereare，indeed，somecommoditiesofwhichthepriceismadeupoftwoofthosepartsonly，thewagesoflabour，andtheprofitsofstock:andaveryfewinwhichitconsistsaltogetherinone，thewagesoflabour:butthatthepriceofeverycommoditynecessarilyresolvesitselfintosomeone，orother，orallofthesethreeparts;everypartofitwhichgoesneithertorentnortowages，beingnecessarilyprofittosomebody。
Sincethisisthecase，ithasbeenobserved，withregardtoeveryparticularcommodity，takenseparately，itmustbesowithregardtoallthecommoditieswhichcomposethewholeannualproduceofthelandandlabourofeverycountry，takencomplexly。
Thewholepriceorexchangeablevalueofthatannualproducemustresolveitselfintothesamethreeparts，andbeparcelledoutamongthedifferentinhabitantsofthecountry，eitherasthewagesoftheirlabour，theprofitsoftheirstock，ortherentoftheirland。
Butthoughthewholevalueoftheannualproduceofthelandandlabourofeverycountryisthusdividedamongandconstitutesarevenuetoitsdifferentinhabitants，yetasintherentofaprivateestatewedistinguishbetweenthegrossrentandthenetrent，somaywelikewiseintherevenueofalltheinhabitantsofagreatcountry。
Thegrossrentofaprivateestatecomprehendswhateverispaidbythefarmer;thenetrent，whatremainsfreetothelandlord，afterdeductingtheexpenseofmanagement，ofrepairs，andallothernecessarycharges;orwhat，withouthurtinghisestate，hecanaffordtoplaceinhisstockreservedforimmediateconsumption，ortospenduponhistable，equipage，theornamentsofhishouseandfurniture，hisprivateenjoymentsandamusements。Hisrealwealthisinproportion，nottohisgross，buttohisnetrent。

Thewholeexpenseofmaintainingthefixedcapitalmustevidentlybeexcludedfromthenetrevenueofthesociety。
Neitherthematerialsnecessaryforsupportingtheirusefulmachinesandinstrumentsoftrade，theirprofitablebuildings，etc。，northeproduceofthelabournecessaryforfashioningthosematerialsintotheproperform，canevermakeanypartofit。Thepriceofthatlabourmayindeedmakeapartofit;astheworkmensoemployedmayplacethewholevalueoftheirwagesintheirstockreservedforimmediateconsumption。Butinothersortsoflabour，boththepriceandtheproducegotothisstock，thepricetothatoftheworkmen，theproducetothatofotherpeople，whosesubsistence，conveniences，andamusements，areaugmentedbythelabourofthoseworkmen。
Theintentionofthefixedcapitalistoincreasetheproductivepowersoflabour，ortoenablethesamenumberoflabourerstoperformamuchgreaterquantityofwork。Inafarmwhereallthenecessarybuildings，fences，drains，communications，etc。，areinthemostperfectgoodorder，thesamenumberoflabourersandlabouringcattlewillraiseamuchgreaterproducethaninoneofequalextentandequallygoodground，butnotfurnishedwithequalconveniencies。Inmanufacturesthesamenumberofhands，assistedwiththebestmachinery，willworkupamuchgreaterquantityofgoodsthanwithmoreimperfectinstrumentsoftrade。Theexpensewhichisproperlylaidoutuponafixedcapitalofanykind，isalwaysrepaidwithgreatprofit，andincreasestheannualproducebyamuchgreatervaluethanthatofthesupportwhichsuchimprovementsrequire。Thissupport，however，stillrequiresacertainportionofthatproduce。Acertainquantityofmaterials，andthelabourofacertainnumberofworkmen，bothofwhichmighthavebeenimmediatelyemployedtoaugmentthefood，clothingandlodging，thesubsistenceandconvenienciesofthesociety，arethusdivertedtoanotheremployment，highlyadvantageousindeed，butstilldifferentfromthisone。Itisuponthisaccountthatallsuchimprovementsinmechanics，asenablethesamenumberofworkmentoperformanequalquantityofwork，withcheaperandsimplermachinerythanhadbeenusualbefore，arealwaysregardedasadvantageoustoeverysociety。A
certainquantityofmaterials，andthelabourofacertainnumberofworkmen，whichhadbeforebeenemployedinsupportingamorecomplexandexpensivemachinery，canafterwardsbeappliedtoaugmentthequantityofworkwhichthatoranyothermachineryisusefulonlyforperforming。Theundertakerofsomegreatmanufactorywhoemploysathousandayearinthemaintenanceofhismachinery，ifhecanreducethisexpensetofivehundredwillnaturallyemploytheotherfivehundredinpurchasinganadditionalquantityofmaterialstobewroughtupbyanadditionalnumberofworkmen。Thequantityofthatwork，therefore，whichhismachinerywasusefulonlyforperforming，willnaturallybeaugmented，andwithitalltheadvantageandconveniencywhichthesocietycanderivefromthatwork。
Theexpenseofmaintainingthefixedcapitalinagreatcountrymayveryproperlybecomparedtothatofrepairsinaprivateestate。Theexpenseofrepairsmayfrequentlybenecessaryforsupportingtheproduceoftheestate，andconsequentlyboththegrossandthenetrentofthelandlord。
Whenbyamoreproperdirection，however，itcanbediminishedwithoutoccasioninganydiminutionofproduce，thegrossrentremainsatleastthesameasbefore，andthenetrentisnecessarilyaugmented。
Butthoughthewholeexpenseofmaintainingthefixedcapitalisthusnecessarilyexcludedfromthenetrevenueofthesociety，itisnotthesamecasewiththatofmaintainingthecirculatingcapital。Ofthefourpartsofwhichthislattercapitaliscomposed—money，provisions，materials，andfinishedwork—thethreelast，ithasalreadybeenobserved，areregularlywithdrawnfromit，andplacedeitherinthefixedcapitalofthesociety，orintheirstockreservedforimmediateconsumption。
Whateverportionofthoseconsumablegoodsisemployedinmaintainingtheformer，goesalltothelatter，andmakesapartofthenetrevenueofthesociety。Themaintenanceofthosethreepartsofthecirculatingcapital，therefore，withdrawsnoportionoftheannualproducefromthenetrevenueofthesociety，besideswhatisnecessaryformaintainingthefixedcapital。
Thecirculatingcapitalofasocietyisinthisrespectdifferentfromthatofanindividual。Thatofanindividualistotallyexcludedfrommakinganypartofhisnetrevenue，whichmustconsistaltogetherinhisprofits。Butthoughthecirculatingcapitalofeveryindividualmakesapartofthatofthesocietytowhichhebelongs，itisnotuponthataccounttotallyexcludedfrommakingapartlikewiseoftheirnetrevenue。Thoughthewholegoodsinamerchant’sshopmustbynomeansbeplacedinhisownstockreservedforimmediateconsumption，theymayinthatofotherpeople，who，fromarevenuederivedfromotherfunds，mayregularlyreplacetheirvaluetohim，togetherwithitsprofits，withoutoccasioninganydiminutioneitherofhiscapitaloroftheirs。

Itistheambiguityoflanguageonlywhichcanmakethispropositionappeareitherdoubtfulorparadoxical。Whenproperlyexplainedandunderstood，itisalmostself—evident。

When，byanyparticularsumofmoney，wemeannotonlytoexpresstheamountofthemetalpiecesofwhichitiscomposed，buttoincludeinitssignificationsomeobscurereferencetothegoodswhichcanbehadinexchangeforthem，thewealthorrevenuewhichitinthiscasedenotes，isequalonlytooneofthetwovalueswhicharethusintimatedsomewhatambiguouslybythesameword，andtothelattermoreproperlythantotheformer，tothemoney’sworthmoreproperlythantothemoney。
Thusifaguineabetheweeklypensionofaparticularperson，hecaninthecourseoftheweekpurchasewithitacertainquantityofsubsistence，conveniencies，andamusements。
Inproportionasthisquantityisgreatorsmall，soarehisrealriches，hisrealweeklyrevenue。Hisweeklyrevenueiscertainlynotequalbothtotheguinea，andtowhatcanbepurchasedwithit，butonlytooneorotherofthosetwoequalvalues;andtothelattermoreproperlythantotheformer，totheguinea’sworthratherthantotheguinea。
Ifthepensionofsuchapersonwaspaidtohim，notingold，butinaweeklybillforaguinea，hisrevenuesurelywouldnotsoproperlyconsistinthepieceofpaper，asinwhathecouldgetforit。Aguineamaybeconsideredasabillforacertainquantityofnecessariesandconvenienciesuponallthetradesmenintheneighbourhood。Therevenueofthepersontowhomitispaid，doesnotsoproperlyconsistinthepieceofgold，asinwhathecangetforit，orinwhathecanexchangeitfor。Ifitcouldbeexchangedfornothing，itwould，likeabilluponabankrupt，beofnomorevaluethanthemostuselesspieceofpaper。
Thoughtheweeklyoryearlyrevenueofallthedifferentinhabitantsofanycountry，inthesamemanner，maybe，andinrealityfrequentlyispaidtotheminmoney，theirrealriches，however，therealweeklyoryearlyrevenueofallofthemtakentogether，mustalwaysbegreatorsmallinproportiontothequantityofconsumablegoodswhichtheycanallofthempurchasewiththismoney。Thewholerevenueofallofthemtakentogetherisevidentlynotequaltoboththemoneyandtheconsumablegoods;butonlytooneorotherofthosetwovalues，andtothelattermoreproperlythantotheformer。
Thoughwefrequently，therefore，expressaperson’srevenuebythemetalpieceswhichareannuallypaidtohim，itisbecausetheamountofthosepiecesregulatestheextentofhispowerofpurchasing，orthevalueofthegoodswhichhecanannuallyaffordtoconsume。Westillconsiderhisrevenueasconsistinginthispowerofpurchasingorconsuming，andnotinthepieceswhichconveyit。
Butifthisissufficientlyevidentevenwithregardtoanindividual，itisstillmoresowithregardtoasociety。Theamountofthemetalpieceswhichareannuallypaidtoanindividual，isoftenpreciselyequaltohisrevenue，andisuponthataccounttheshortestandbestexpressionofitsvalue。Buttheamountofthemetalpieceswhichcirculateinasocietycanneverbeequaltotherevenueofallitsmembers。Asthesameguineawhichpaystheweeklypensionofonemanto—day，maypaythatofanotherto—morrow，andthatofathirdthedaythereafter，theamountofthemetalpieceswhichannuallycirculateinanycountrymustalwaysbeofmuchlessvaluethanthewholemoneypensionsannuallypaidwiththem。Butthepowerofpurchasing，orthegoodswhichcansuccessivelybeboughtwiththewholeofthosemoneypensionsastheyaresuccessivelypaid，mustalwaysbepreciselyofthesamevaluewiththosepensions;

Money，therefore，thegreatwheelofcirculation，thegreatinstrumentofcommerce，likeallotherinstrumentsoftrade，thoughitmakesapartandaveryvaluablepartofthecapital，makesnopartoftherevenueofthesocietytowhichitbelongs;
andthoughthemetalpiecesofwhichitiscomposed，inthecourseoftheirannualcirculation，distributetoeverymantherevenuewhichproperlybelongstohim，theymakethemselvesnopartofthatrevenue。
Thirdly，andlastly，themachinesandinstrumentsoftrade，etc。，whichcomposethefixedcapital，bearthisfurtherresemblancetothatpartofthecirculatingcapitalwhichconsistsinmoney;thataseverysavingintheexpenseoferectingandsupportingthosemachines，whichdoesnotdiminishtheproductivepowersoflabour，isanimprovementofthenetrevenueofthesociety，soeverysavingintheexpenseofcollectingandsupportingthatpartofthecirculatingcapitalwhichconsistsinmoney，isanimprovementofexactlythesamekind。
Itissufficientlyobvious，andithaspartly，too，beenexplainedalready，inwhatmannereverysavingintheexpenseofsupportingthefixedcapitalisanimprovementofthenetrevenueofthesociety。Thewholecapitaloftheundertakerofeveryworkisnecessarilydividedbetweenhisfixedandhiscirculatingcapital。Whilehiswholecapitalremainsthesame，thesmallertheonepart，thegreatermustnecessarilybetheother。Itisthecirculatingcapitalwhichfurnishesthematerialsandwagesoflabour，andputsindustryintomotion。Everysaving，therefore，intheexpenseofmaintainingthefixedcapital，whichdoesnotdiminishtheproductivepowersoflabour，mustincreasethefundwhichputsindustryintomotion，andconsequentlytheannualproduceoflandandlabour，therealrevenueofeverysociety。
Thesubstitutionofpaperintheroomofgoldandsilvermoney，replacesaveryexpensiveinstrumentofcommercewithonemuchlesscostly，andsometimesequallyconvenient。Circulationcomestobecarriedonbyanewwheel，whichitcostslessbothtoerectandtomaintainthantheoldone。Butinwhatmannerthisoperationisperformed，andinwhatmannerittendstoincreaseeitherthegrossorthenetrevenueofthesociety，isnotaltogethersoobvious，andmaythereforerequiresomefurtherexplication。
Thereareseveraldifferentsortsofpapermoney;butthecirculatingnotesofbanksandbankersarethespecieswhichisbestknown，andwhichseemsbestadaptedforthispurpose。
Whenthepeopleofanyparticularcountryhavesuchconfidenceinthefortune，probity，andprudenceofaparticularbanker，astobelievethatheisalwaysreadytopayupondemandsuchofhispromissorynotesasarelikelytobeatanytimepresentedtohim;thosenotescometohavethesamecurrencyasgoldandsilvermoney，fromtheconfidencethatsuchmoneycanatanytimebehadforthem。

Thoughhehasgenerallyincirculation，therefore，notestotheextentofahundredthousandpounds，twentythousandpoundsingoldandsilvermayfrequentlybeasufficientprovisionforansweringoccasionaldemands。Bythisoperation，therefore，twentythousandpoundsingoldandsilverperformallthefunctionswhichahundredthousandcouldotherwisehaveperformed。Thesameexchangesmaybemade，thesamequantityofconsumablegoodsmaybecirculatedanddistributedtotheirproperconsumers，bymeansofhispromissorynotes，tothevalueofahundredthousandpounds，asbyanequalvalueofgoldandsilvermoney。Eightythousandpoundsofgoldandsilver，therefore，can，inthismanner，besparedfromthecirculationofthecountry;andifdifferentoperationsofthesamekindshould，atthesametime，becarriedonbymanydifferentbanksandbankers，thewholecirculationmaythusbeconductedwithafifthpartonlyofthegoldandsilverwhichwouldotherwisehavebeenrequisite。
Letussuppose，forexample，thatthewholecirculatingmoneyofsomeparticularcountryamounted，ataparticulartime，toonemillionsterling，thatsumbeingthensufficientforcirculatingthewholeannualproduceoftheirlandandlabour。
Letussuppose，too，thatsometimethereafter，differentbanksandbankersissuedpromissorynotes，payabletothebearer，totheextentofonemillion，reservingintheirdifferentcofferstwohundredthousandpoundsforansweringoccasionaldemands。
Therewouldremain，therefore，incirculation，eighthundredthousandpoundsingoldandsilver，andamillionofbanknotes，oreighteenhundredthousandpoundsofpaperandmoneytogether。
Buttheannualproduceofthelandandlabourofthecountryhadbeforerequiredonlyonemilliontocirculateanddistributeittoitsproperconsumers，andthatannualproducecannotbeimmediatelyaugmentedbythoseoperationsofbanking。Onemillion，therefore，willbesufficienttocirculateitafterthem。Thegoodstobeboughtandsoldbeingpreciselythesameasbefore，thesamequantityofmoneywillbesufficientforbuyingandsellingthem。Thechannelofcirculation，ifImaybeallowedsuchanexpression，willremainpreciselythesameasbefore。Onemillionwehavesupposedsufficienttofillthatchannel。
Whatever，therefore，ispouredintoitbeyondthissumcannotruninit，butmustoverflow。Onemillioneighthundredthousandpoundsarepouredintoit。Eighthundredthousandpounds，therefore，mustoverflow，thatsumbeingoverandabovewhatcanbeemployedinthecirculationofthecountry。Butthoughthissumcannotbeemployedathome，itistoovaluabletobeallowedtolieidle。Itwill，therefore，besentabroad，inordertoseekthatprofitableemploymentwhichitcannotfindathome。Butthepapercannotgoabroad;becauseatadistancefromthebankswhichissueit，andfromthecountryinwhichpaymentofitcanbeexactedbylaw，itwillnotbereceivedincommonpayments。
Goldandsilver，therefore，totheamountofeighthundredthousandpoundswillbesentabroad，andthechannelofhomecirculationwillremainfilledwithamillionofpaper，insteadofthemillionofthosemetalswhichfilleditbefore。
Butthoughsogreataquantityofgoldandsilveristhussentabroad，wemustnotimaginethatitissentabroadfornothing，orthatitsproprietorsmakeapresentofittoforeignnations。Theywillexchangeitforforeigngoodsofsomekindoranother，inordertosupplytheconsumptioneitherofsomeotherforeigncountryoroftheirown。
Iftheyemployitinpurchasinggoodsinoneforeigncountryinordertosupplytheconsumptionofanother，orinwhatiscalledthecarryingtrade，whateverprofittheymakewillbeanadditiontothenetrevenueoftheirowncountry。Itislikeanewfund，createdforcarryingonanewtrade;domesticbusinessbeingnowtransactedbypaper，andthegoldandsilverbeingconvertedintoafundforthisnewtrade。
Iftheyemployitinpurchasingforeigngoodsforhomeconsumption，theymayeither，first，purchasesuchgoodsasarelikelytobeconsumedbyidlepeoplewhoproducenothing，suchasforeignwines，foreignsilks，etc。;or，secondly，theymaypurchaseanadditionalstockofmaterials，tools，andprovisions，inordertomaintainandemployanadditionalnumberofindustriouspeople，whoreproduce，withaprofit，thevalueoftheirannualconsumption。
Sofarasitisemployedinthefirstway，itpromotesprodigality，increasesexpenseandconsumptionwithoutincreasingproduction，orestablishinganypermanentfundforsupportingthatexpense，andisineveryrespecthurtfultothesociety。
Sofarasitisemployedinthesecondway，itpromotesindustry;andthoughitincreasestheconsumptionofthesociety，itprovidesapermanentfundforsupportingthatconsumption，thepeoplewhoconsumereproducing，withaprofit，thewholevalueoftheirannualconsumption。Thegrossrevenueofthesociety，theannualproduceoftheirlandandlabour，isincreasedbythewholevaluewhichthelabourofthoseworkmenaddstothematerialsuponwhichtheyareemployed;andtheirnetrevenuebywhatremainsofthisvalue，afterdeductingwhatisnecessaryforsupportingthetoolsandinstrumentsoftheirtrade。
Thatthegreaterpartofthegoldandsilverwhich，beingforcedabroadbythoseoperationsofbanking，isemployedinpurchasingforeigngoodsforhomeconsumption，isandmustbeemployedinpurchasingthoseofthissecondkind，seemsnotonlyprobablebutalmostunavoidable。Thoughsomeparticularmenmaysometimesincreasetheirexpenseveryconsiderablythoughtheirrevenuedoesnotincreaseatall，wemaybeassuredthatnoclassororderofmeneverdoesso;because，thoughtheprinciplesofcommonprudencedonotalwaysgoverntheconductofeveryindividual，theyalwaysinfluencethatofthemajorityofeveryclassororder。Buttherevenueofidlepeople，consideredasaclassororder，cannot，inthesmallestdegree，beincreasedbythoseoperationsofbanking。Theirexpenseingeneral，therefore，cannotbemuchincreasedbythem，thoughthatofafewindividualsamongthemmay，andinrealitysometimesis。Thedemandofidlepeople，therefore，forforeigngoodsbeingthesame，orverynearlythesame，asbefore，averysmallpartofthemoney，whichbeingforcedabroadbythoseoperationsofbanking，isemployedinpurchasingforeigngoodsforhomeconsumption，islikelytobeemployedinpurchasingthosefortheiruse。Thegreaterpartofitwillnaturallybedestinedfortheemploymentofindustry，andnotforthemaintenanceofidleness。
Whenwecomputethequantityofindustrywhichthecirculatingcapitalofanysocietycanemploy，wemustalwayshaveregardtothosepartsofitonlywhichconsistinprovisions，materials，andfinishedwork:theother，whichconsistsinmoney，andwhichservesonlytocirculatethosethree，mustalwaysbededucted。Inordertoputindustryintomotion，threethingsarerequisite;materialstoworkupon，toolstoworkwith，andthewagesorrecompenseforthesakeofwhichtheworkisdone。Moneyisneitheramaterialtoworkupon，noratooltoworkwith;andthoughthewagesoftheworkmanarecommonlypaidtohiminmoney，hisrealrevenue，likethatofallothermen，consists，notinmoney，butinthemoney’sworth;notinthemetalpieces，butinwhatcanbegotforthem。
Thequantityofindustrywhichanycapitalcanemploymust，evidently，beequaltothenumberofworkmenwhomitcansupplywithmaterials，tools，andamaintenancesuitabletothenatureofthework。Moneymayberequisiteforpurchasingthematerialsandtoolsofthework，aswellasthemaintenanceoftheworkmen。
Butthequantityofindustrywhichthewholecapitalcanemployiscertainlynotequalbothtothemoneywhichpurchases，andtothematerials，tools，andmaintenance，whicharepurchasedwithit;butonlytooneorotherofthosetwovalues，andtothelattermoreproperlythantotheformer。
Whenpaperissubstitutedintheroomofgoldandsilvermoney，thequantityofthematerials，tools，andmaintenance，whichthewholecirculatingcapitalcansupply，maybeincreasedbythewholevalueofgoldandsilverwhichusedtobeemployedinpurchasingthem。Thewholevalueofthegreatwheelofcirculationanddistributionisaddedtothegoodswhicharecirculatedanddistributedbymeansofit。Theoperation，insomemeasure，resemblesthatoftheundertakerofsomegreatwork，who，inconsequenceofsomeimprovementinmechanics，takesdownhisoldmachinery，andaddsthedifferencebetweenitspriceandthatofthenewtohiscirculatingcapital，tothefundfromwhichhefurnishesmaterialsandwagestohisworkmen。
Whatistheproportionwhichthecirculatingmoneyofanycountrybearstothewholevalueoftheannualproducecirculatedbymeansofit，itis，perhaps，impossibletodetermine。Ithasbeencomputedbydifferentauthorsatafifth，atatenth，atatwentieth，andatathirtiethpartofthatvalue。Buthowsmallsoevertheproportionwhichthecirculatingmoneymaybeartothewholevalueoftheannualproduce，asbutapart，andfrequentlybutasmallpart，ofthatproduce，iseverdestinedforthemaintenanceofindustry，itmustalwaysbearaveryconsiderableproportiontothatpart。When，therefore，bythesubstitutionofpaper，thegoldandsilvernecessaryforcirculationisreducedto，perhaps，afifthpartoftheformerquantity，ifthevalueofonlythegreaterpartoftheotherfour—fifthsbeaddedtothefundswhicharedestinedforthemaintenanceofindustry，itmustmakeaveryconsiderableadditiontothequantityofthatindustry，and，consequently，tothevalueoftheannualproduceoflandandlabour。
