  naturalist；　one　of　the　Morleys　of　Glynde　in　Sussex；　the　Relfes　from
  Mayfield；　and　the　Cheneys　from　Crawley。
  Notwithstanding　these　migrations　of　enterprising　manufacturers；　the
  iron　trade　of　Sussex　continued　to　exist　until　the　middle　of　the
  seventeenth　century；　when　the　waste　of　timber　was　again　urged　upon
  the　attention　of　Parliament；　and　the　penalties　for　infringing　the
  statutes　seem　to　have　been　more　rigorously　enforced。　　The　trade　then
  suffered　a　more　serious　check；　and　during　the　civil　wars；　a　heavy
  blow　was　given　to　it　by　the　destruction　of　the　works　belonging　to　all
  royalists；　which　was　accomplished　by　a　division　of　the　army　under　Sir
  William　Waller。　　Most　of　the　Welsh　ironworks　were　razed　to　the　ground
  about　the　same　time；　and　were　not　again　rebuilt。　　And　after　the
  Restoration；　in　1674；　all　the　royal　ironworks　in　the　Forest　of　Dean
  were　demolished；　leaving　only　such　to　be　supplied　with　ore　as　were
  beyond　the　forest　limits；　the　reason　alleged　for　this　measure　being
  lest　the　iron　manufacture　should　endanger　the　supply　of　timber
  required　for　shipbuilding　and　other　necessary　purposes。
  From　this　time　the　iron　manufacture　of　Sussex；　as　of　England
  generally；　rapidly　declined。　　In　1740　there　were　only　fifty…nine
  furnaces　in　all　England；　of　which　ten　were　in　Sussex；　and　in　1788
  there　were　only　two。　　A　few　years　later；　and　the　Sussex　iron　furnaces
  were　blown　out　altogether。　　Farnhurst；　in　western；　and　Ashburnham；　in
  eastern　Sussex；　witnessed　the　total　extinction　of　the　manufacture。
  The　din　of　the　iron　hammer　was　hushed；　the　glare　of　the　furnace
  faded；　the　last　blast　of　the　bellows　was　blown；　and　the　district
  returned　to　its　original　rural　solitude。　　Some　of　the　furnace…ponds
  were　drained　and　planted　with　hops　or　willows；　others　formed
  beautiful　lakes　in　retired　pleasure…grounds；　while　the　remainder　were
  used　to　drive　flour…mills；　as　the　streams　in　North　Kent；　instead　of
  driving　fulling…mills；　were　employed　to　work　paper…mills。　　All　that
  now　remains　of　the　old　iron…works　are　the　extensive　beds　of　cinders
  from　which　material　is　occasionally　taken　to　mend　the　Sussex　roads；
  and　the　numerous　furnace…ponds；　hammer…posts；　forges；　and　cinder

  these　men　a　great　part；　not　only　of　this　Island；　but　also　of　his
  Majestie's　other　Kingdoms　and　Territories；　with　Iron　wares　have　their
  supply；　and　Wood　in　these　parts　almost　exhausted；　although　it　were　of
  late　a　mighty　woodland　country。〃DUDLEY's　Metallum　Martis；　1665。
  The　severe　restrictions　enforced　by　the　legislature　against　the　use
  of　wood　in　iron…smelting　had　the　effect　of　almost　extinguishing　the
  manufacture。　　New　furnaces　ceased　to　be　erected；　and　many　of　the　old
  ones　were　allowed　to　fall　into　decay；　until　it　began　to　be　feared
  that　this　important　branch　of　industry　would　become　completely　lost。
  The　same　restrictions　alike　affected　the　operations　of　the　glass
  manufacture；　which；　with　the　aid　of　foreign　artisans；　had　been
  gradually　established　in　England；　and　was　becoming　a　thriving　branch
  of　trade。　　It　was　even　proposed　that　the　smelting　of　iron　should　be
  absolutely　prohibited：　　〃many　think；〃　said　a　contemporary　writer；
  〃that　there　should　be　NO　WORKS　ANYWHEREthey　do　so　devour　the
  woods。〃
  The　use　of　iron；　however；　could　not　be　dispensed　with。　　The　very
  foundations　of　society　rested　upon　an　abundant　supply　of　it；　for
  tools　and　implements　of　peace；　as　well　as　for　weapons　of　war。　　In　the
  dearth　of　the　article　at　home；　a　supply　of　it　was　therefore　sought
  for　abroad；　and　both　iron　and　steel　came　to　be　imported　in
  largely…increased　quantities。　　This　branch　of　trade　was　principally　in
  the　hands　of　the　Steelyard　Company　of　Foreign　Merchants；　established
  in　Upper　Thames　Street；　a　little　above　London　Bridge；　and　they
  imported　large　quantities　of　iron　and　steel　from　foreign　countries；
  principally　from　Sweden；　Germany；　and　Spain。　　The　best　iron　came　from
  Spain；　though　the　Spaniards　on　their　part　coveted　our　English　made
  cannons；　which　were　better　manufactured　than　theirs；　while　the　best
  steel　came　from　Germany　and　Sweden。*

  Under　these　circumstances；　it　was　natural　that　persons　interested　in
  the　English　iron　manufacture　should　turn　their　attention　to　some
  other　description　of　fuel　which　should　serve　as　a　substitute　for　the
  prohibited　article。　　There　was　known　to　be　an　abundance　of　coal　in　the
  northern　and　midland　counties；　and　it　occurred　to　some　speculators
  more　than　usually　daring；　to　propose　it　as　a　substitute　for　the
  charcoal　fuel　made　from　wood。　　But　the　same　popular　prejudice　which
  existed　against　the　use　of　coal　for　domestic　purposes；　prevented　its
  being　employed　for　purposes　of　manufacture；　and　they　were　thought
  very　foolish　persons　indeed　who　first　promulgated　the　idea　of
  smelting　iron　by　means　of　pit…coal。　　The　old　manufacturers　held　it　to
  be　impossible　to　reduce　the　ore　in　any　other　way　than　by　means　of
  charcoal　of　wood。　　It　was　only　when　the　wood　in　the　neighbourhood　of
  the　ironworks　had　been　almost　entirely　burnt　up；　that　the
  manufacturers　were　driven　to　entertain　the　idea　of　using　coal　as　a
  substitute；　but　more　than　a　hundred　years　passed　before　the　practice
  of　smelting　iron　by　its　means　became　general。
  The　first　who　took　out　a　patent　for　the　purpose　was　one　Simon
  Sturtevant；　a　German　skilled　in　mining　operations；　the　professed

  the　operations　of　industry　were　then　treated　as　secrets。　　Each　trade
