But  it  may  come  to  pass  that  the  husbandman,
land-owner,  or  whoever  he  be  that  is  entiled  to
the  produce  of  the  soil,  will  no  longer  exchange  it
for  what  the  munnliu  turer  has  to  ofier.  Pie  is
already  sujiplicd  to  the  extent  of  his  desires.  For
instance,  he  wants  no  more  cloth ;  he  will  no
longer  therefore  give  the  weaver  corn  in  return
for  the  produce  of  his  looms :  but  he  would  readily
give  it  for  tea,  or  for  wine.     When  the  weaver

finds  this  to  be  the  case,  he  has  nothing  to  do  but
to  send  his  clotii  abroad,  in  exchange  for  tea  or
for  wine,  which  he  m.iy  barter  tor  that  provision
■which  the  oti»?r  of  liis  cloth  will  no  longer  procure.
The  circulation  is  thus  revi\ed :  and  the  benelit
of  the  discovery  is,  that,  whereas  the  number  of
weavers,  who  could  find  subsistence  from  their
employment,  was  before  hmited  by  the  consump-
tion oi"  clotli  in  the  country,  that  number  is  now
augmented,  in  proportion  to  the  demand  for  tea
and  wine.  This  is  the  principle  oi  foreign  com-
merce. In  the  magnitude  and  complexity  of  the
macliine,  the  principle  of  motion  is  sometimes  lost
or  unobserved  ;  but  it  is  always  simple  and  the
same,  to  whatever  extent  it  may  be  diversilied
and  enlarged  in  its  operation.
