country；　but　upon　the　richness　or　poverty　of　the　mines；　which
  happen　at　any　particular　time　to　supply　the　great　market　of　the
  commercial　world　with　those　metals。　It　depends　upon　the
  proportion　between　the　quantity　of　labour　which　is　necessary　in
  order　to　bring　a　certain　quantity　of　gold　and　silver　to　market；
  and　that　which　is　necessary　in　order　to　bring　thither　a　certain
  quantity　of　any　other　sort　of　goods。
  If　bankers　are　restrained　from　issuing　any　circulating　bank
  notes；　or　notes　payable　to　the　bearer；　for　less　than　a　certain
  sum；　and　if　they　are　subjected　to　the　obligation　of　an　immediate
  and　unconditional　payment　of　such　bank　notes　as　soon　as
  presented；　their　trade　may；　with　safety　to　the　public；　be
  rendered　in　all　other　respects　perfectly　free。　The　late
  multiplication　of　banking　companies　in　both　parts　of　the　United
  Kingdom；　an　event　by　which　many　people　have　been　much　alarmed；
  instead　of　diminishing；　increases　the　security　of　the　public。　It
  obliges　all　of　them　to　be　more　circumspect　in　their　conduct；　and；
  by　not　extending　their　currency　beyond　its　due　proportion　to
  their　cash；　to　guard　themselves　against　those　malicious　runs
  which　the　rivalship　of　so　many　competitors　is　always　ready　to
  bring　upon　them。　It　restrains　the　circulation　of　each　particular
  company　within　a　narrower　circle；　and　reduces　their　circulating
  notes　to　a　smaller　number。　By　dividing　the　whole　circulation　into
  a　greater　number　of　parts；　the　failure　of　any　one　company；　an
  accident　which；　in　the　course　of　things；　must　sometimes　happen；
  becomes　of　less　consequence　to　the　public。　This　free　competition；
  too；　obliges　all　bankers　to　be　more　liberal　in　their　dealings
  with　their　customers；　lest　their　rivals　should　carry　them　away。
  In　general；　if　any　branch　of　trade；　or　any　division　of　labour；　be
  advantageous　to　the　public；　the　freer　and　more　general　the
  competition；　it　will　always　be　the　more　so。
  CHAPTER　III
  Of　the　Accumulation　of　Capital；　or　of　Productive　and　Unproductive
  Labour
  THERE　is　one　sort　of　labour　which　adds　to　the　value　of　the
  subject　upon　which　it　is　bestowed：　there　is　another　which　has　no
  such　effect。　The　former；　as　it　produces　a　value；　may　be　called
  productive；　the　latter；　unproductive　labour。　Thus　the　labour　of　a
  manufacturer　adds；　generally；　to　the　value　of　the　materials　which
  he　works　upon；　that　of　his　own　maintenance；　and　of　his　master's
  profit。　The　labour　of　a　menial　servant；　on　the　contrary；　adds　to
  the　value　of　nothing。　Though　the　manufacturer　has　his　wages
  advanced　to　him　by　his　master；　he；　in　reality；　costs　him　no
  expense；　the　value　of　those　wages　being　generally　restored；
  together　with　a　profit；　in　the　improved　value　of　the　subject　upon
  which　his　labour　is　bestowed。　But　the　maintenance　of　a　menial
  servant　never　is　restored。　A　man　grows　rich　by　employing　a
  multitude　of　manufacturers：　he　grows　poor　by　maintaining　a
  multitude　of　menial　servants。　The　labour　of　the　latter；　however；
  has　its　value；　and　deserves　its　reward　as　well　as　that　of　the
  former。　But　the　labour　of　the　manufacturer　fixes　and　realizes
  itself　in　some　particular　subject　or　vendible　commodity；　which
  lasts　for　some　time　at　least　after　that　labour　is　past。　It　is；　as
  it　were；　a　certain　quantity　of　labour　stocked　and　stored　up　to　be
  employed；　if　necessary；　upon　some　other　occasion。　That　subject；
  or　what　is　the　same　thing；　the　price　of　that　subject；　can
  afterwards；　if　necessary；　put　into　motion　a　quantity　of　labour
  equal　to　that　which　had　originally　produced　it。　The　labour　of　the
  menial　servant；　on　the　contrary；　does　not　fix　or　realize　itself
  in　any　particular　subject　or　vendible　commodity。　His　services
  generally　perish　in　the　very　instant　of　their　performance；　and
  seldom　leave　any　trace　or　value　behind　them　for　which　an　equal
  quantity　of　service　could　afterwards　be　procured。
  The　labour　of　some　of　the　most　respectable　orders　in　the
  society　is；　like　that　of　menial　servants；　unproductive　of　any
  value；　and　does　not　fix　or　realize　itself　in　any　permanent
  subject；　or　vendible　commodity；　which　endures　after　that　labour
  is　past；　and　for　which　an　equal　quantity　of　labour　could
  afterwards　be　procured。　The　sovereign；　for　example；　with　all　the
  officers　both　of　justice　and　war　who　serve　under　him；　the　whole
  army　and　navy；　are　unproductive　labourers。　They　are　the　servants
  of　the　public；　and　are　maintained　by　a　part　of　the　annual　produce
  of　the　industry　of　other　people。　Their　service；　how　honourable；
  how　useful；　or　how　necessary　soever；　produces　nothing　for　which
  an　equal　quantity　of　service　can　afterwards　be　procured。　The
  protection；　security；　and　defence　of　the　commonwealth；　the　effect
  of　their　labour　this　year　will　not　purchase　its　protection；
  security；　and　defence　for　the　year　to　come。　In　the　same　class
  must　be　ranked；　some　both　of　the　gravest　and　most　important；　and
  some　of　the　most　frivolous　professions：　churchmen；　lawyers；
  physicians；　men　of　letters　of　all　kinds；　players；　buffoons；
  musicians；　opera…singers；　opera…dancers；　etc。　The　labour　of　the
  meanest　of　these　has　a　certain　value；　regulated　by　the　very　same
  principles　which　regulate　that　of　every　other　sort　of　labour；　and
  that　of　the　n　oblest　and　most　useful；　50　produces　nothing　which
  could　afterwards　purchase　or　procure　an　equal　quantity　of　labour。
  Like　the　declamation　of　the　actor；　the　harangue　of　the　orator；　or
  the　tune　of　the　musician；　the　work　of　all　of　them　perishes　in　the
  very　instant　of　its　production。
  Both　productive　and　unproductive　labourers；　and　those　who　do
  not　labour　at　all；　are　all　equally　maintained　by　the　annual
  produce　of　the　land　and　labour　of　the　country。　This　produce；　how
  great　soever；　can　never　be　infinite；　but　must　have　certain
  limits。　According；　therefore；　as　a　smaller　or　greater　proportion
  of　it　is　in　any　one　year　employed　in　maintaining　unproductive
  hands；　the　more　in　the　one　case　and　the　less　in　the　other　will
  remain　for　the　productive；　and　the　next　year's　produce　will　be
  greater　or　smaller　accordingly；　the　whole　annual　produce；　if　we
  except　the　spontaneous　productions　of　the　earth；　being　the　effect
  of　productive　labour。
  Though　the　whole　annual　produce　of　the　land　and　labour　of
  every　country　is；　no　doubt；　ultimately　destined　for　supplying　the
  consumption　of　its　inhabitants；　and　for　procuring　a　revenue　to
  them；　yet　when　it　first　comes　either　from　the　ground；　or　from　the
  hands　of　the　productive　labourers；　it　naturally　divides　itself
  into　two　parts。　One　of　them；　and　frequently　the　largest；　is；　in
  the　first　place；　destined　for　replacing　a　capital；　or　for
  renewing　the　provisions；　materials；　and　finished　work；　which　had
  been　withdrawn　from　a　capital；　the　other　for　constituting　a
  revenue　either　to　the　owner　of　this　capital；　as　the　profit　of　his
  stock；　or　to　some　other　person；　as　the　rent　of　his　land。　Thus；　of
  the　produce　of　land；　one　part　replaces　the　capital　of　the　farmer；
  the　other　pays　his　profit　and　the　rent　of　the　landlord；　and　thus
  constitutes　a　revenue　both　to　the　owner　of　this　capital；　as　the
  profits　of　his　stock；　and　to　some　other　person；　as　the　rent　of
  his　land。　Of　the　produce　of　a　great　manufactory；　in　the　same
  manner；　one　part；　and　that　always　the　largest；　replaces　the
  capital　of　the　undertaker　of　the　work；　the　other　pays　his　profit；
  and　thus　constitutes　a　revenue　to　the　owner　of　this　capital。
  That　part　of　the　annual　produce　of　the　land　and　labour　of
  any　country　which　replaces　a　capital　never　is　immediately
  employed　to　maintain　any　but　productive　hands。　It　pays　the　wages
  of　productive　labour　only。　That　which　is　immediately　destined　for
  constituting　a　revenue；　either　as　profit　or　as　rent；　may　maintain
  indifferently　either　productive　or　unproductive　hands。
  Whatever　part　of　his　stock　a　man　employs　as　a　capital；　he
  always　expects　is　to　be　replaced　to　him　with　a　profit。　He　employs
  it；　therefore；　in　maintaining　productive　bands　only；　and　after
  having　served　in　the　function　of　a　capital　to　him；　it　constitutes
  a　revenue　to　them。　Whenever　he　employs　any　part　of　it　in
  maintaining　unproductive　hands　of　any　kind；　that　part　is；　from
  that　moment；　withdrawn　from　his　capital；　and　placed　in　his　stock
  reserved　for　immediate　consumption。
  Unproductive　labourers；　and　those　who　do　not　labour　at　all；
  are　all　maintained　by　revenue；　either；　first；　by　that　part　of　the
  annual　produce　which　is　originally　destined　for　constituting　a
  revenue　to　some　particular　persons；　either　as　the　rent　of　land　or
  as　the　profits　of　stock；　or；　secondly；　by　that　part　which；　though
  originally　destined　for　replacing　a　capital　and　for　maintaining
  productive　labourers　only；　yet　when　it　comes　into　their　hands
  whatever　part　of　it　is　over　and　above　their　necessary　subsistence
  may　be　employed　in　maintaining　indifferently　either　productive　or
  unproductive　hands。　Thus；　not　only　the　great　landlord　or　the　rich
  merchant；　but　even　the　common　workman；　if　his　wages　are
  considerable；　may　maintain　a　menial　servant；　or　he　may　sometimes
  go　to　a　play　or　a　puppetshow；　and　so　contribute　his　share　towards
  maintaining　one　set
