  principally because of its many admirable qualities in these latter
  forms that iron maintains its supremacy over all the other metals。
  The process of converting iron into steel had long been known among
  the Eastern nations before it was introduced into Europe。  The Hindoos
  were especially skilled in the art of making steel; as indeed they
  are to this day; and it is supposed that the tools with which the
  Egyptians covered their obelisks and temples of porphyry and syenite
  with hieroglyphics were made of Indian steel; as probably no other
  metal was capable of executing such work。  The art seems to have been
  well known in Germany in the Middle Ages; and the process is on the
  whole very faithfully described by Agricola in his great work on
  Metallurgy。*

  England then produced very little steel; and was mainly dependent for
  its supply of the article upon the continental makers。
  From an early period Sheffield became distinguished for its
  manufacture of iron and steel into various useful articles。  We find
  it mentioned in the thirteenth century as a place where the best
  arrowheads were made;the Earl of Richmond owing his success at the
  battle of Bosworth partly to their superior length; sharpness; and
  finish。  The manufactures of the town became of a more pacific
  character in the following centuries; during which knives; tools; and
  implements of husbandry became the leading articles。
  Chaucer's reference to the 'Sheffield thwytel' (or case…knife) in his
  Canterbury Tales; written about the end of the fourteenth century;
  shows that the place had then become known for its manufacture of
  knives。  In 1575 we find the Earl of Shrewsbury presenting to his
  friend Lord Burleigh 〃a case of Hallamshire whittells; being such
  fruites as his pore cuntrey affordeth with fame throughout the
  realme。〃  Fuller afterwards speaks of the Sheffield knives as 〃for
  common use of the country people;〃 and he cites an instance of a
  knave who cozened him out of fourpence for one when it was only worth
  a penny。
  In 1600 Sheffield became celebrated for its tobacco…boxes and
  Jew's…harps。  The town was as yet of small size and population; for
  when a survey of it was made in 1615 it was found to contain not more
  than 2207 householders; of whom one…third; or 725; were 〃not able to
  live without the charity of their neighbours:  these are all Begging
  poor。〃*

  It must; however; have continued its manufacture of knives; for we
  find that the knife with which Felton stabbed the Duke of Buckingham
  at Portsmouth in 1628 was traced to Sheffield。  The knife was left
  sticking in the duke's body; and when examined was found to bear the
  Sheffield corporation mark。  It was ultimately ascertained to have
  been made by one Wild; a cutler; who had sold the knife for tenpence
  to Felton when recruiting in the town。  At a still later period; the
  manufacture of clasp or spring knives was introduced into Sheffield
  by Flemish workmen。  Harrison says this trade was begun in 1650。  The
  clasp…knife was commonly known in the North as a jocteleg。  Hence
  Burns; describing the famous article treasured by Captain Grose the
  antiquarian; says that
  〃It was a faulding jocteleq;
  Or lang…kail gully;〃
  the word being merely a corruption of Jacques de Liege; a famous
  foreign cutler; whose knives were as well known throughout Europe as
  those of Rogers or Mappin are now。  Scythes and sickles formed other
  branches of manufacture introduced by the Flemish artisans; the
  makers of the former principally living in the parish of Norton;
  those of the latter in Eckington。
  Many improvements were introduced from time to time in the material
  of which these articles were made。  Instead of importing the German
  steel; as it was called; the Sheffield manufacturers began to make it
  themselves; principally from Dannemora iron imported from Sweden。  The
  first English manufacturer of the article was one Crowley; a
  Newcastle man; and the Sheffield makers shortly followed his example。
  We may here briefly state that the ordinary method of preparing this
  valuable material of manufactures is by exposing iron bars; placed in
  contact with roughly…granulated charcoal; to an intense heat;the
  process lasting for about a week; more or less; according to the
  degree of carbonization required。  By this means; what is called
  BLISTERED STEEL is produced; and it furnishes the material out of
  which razors; files; knives; swords; and various articles of hardware
  are manufactured。  A further process is the manufacture of the metal
  thus treated into SHEAR STEEL; by exposing a fasciculus of the
  blistered steel rods; with sand scattered over them for the purposes
  of a flux; to the heat of a wind…furnace until the whole mass becomes
  of a welding heat; when it is taken from the fire and drawn out under
  a forge…hammer;the process of welding being repeated; after which
  the steel is reduced to the required sizes。  The article called FAGGOT
  steel is made after a somewhat similar process。
  But the most valuable form in which steel is now used in the
  manufactures of Sheffield is that of cast…steel; in which iron is
  presented in perhaps its very highest state of perfection。  Cast…steel
  consists of iron united to carbon in an elastic state together with a
  small portion of oxygen; whereas crude or pig iron consists of iron
  combined with carbon in a material state。*

  chief merits of cast…steel consist in its possessing great cohesion
  and closeness of grain; with an astonishing degree of tenacity and
  flexibility; qualities which render it of the highest value in all
  kinds of tools and instruments where durability; polish; and fineness
  of edge are essential requisites。  It is to this material that we are
  mainly indebted for the exquisite cutting instrument of the surgeon;
  the chisel of the sculptor; the steel plate on which the engraver
  practises his art; the cutting tools employed in the various
  processes of skilled handicraft; down to the common saw or the axe
  used by the backwoodsman in levelling the primeval forest。
  The invention of cast…steel is due to Benjamin Huntsman; of
  Attercliffe; near Sheffield。  M。 Le Play; Professor of Metallurgy in
  the Royal School of Mines of France; after making careful inquiry and
  weighing all the evidence on the subject; arrived at the conclusion
  that the invention fairly belongs to Huntsman。  The French professor
  speaks of it as a 〃memorable discovery;〃 made and applied with
  admirable perseverance; and he claims for its inventor the
  distinguished merit of advancing the steel manufactures of Yorkshire
  to the first rank; and powerfully contributing to the establishment
  on a firm foundation of the industrial and commercial supremacy of
  Great Britain。  It is remarkable that a French writer should have been
  among the first to direct public attention to the merits of this
  inventor; and to have first published the few facts known as to his
  history in a French Government Report;showing the neglect which men
  of this class have heretofore received at home; and the much greater
  esteem in which they are held by scientific foreigners。*

  M。 Le Play's two elaborate and admirable reports on the manufacture
  of steel; published in the Annales des Mines; vols。 iii。 and ix。; 4th

  English literature。  They are respectively entitled 'Memoire sur la
  Fabrication de l'Acier en Yorkshire;' and 'Memoire sur le
  Fabrication et le Commerce des Fers a Acier dans le Nord de

  Le Play; in his enthusiastic admiration of the discoverer of so
  potent a metal as cast…steel; paid a visit to Huntsman's grave in
  Atterclifle Churchyard; near Sheffield; and from the inscription on
  his tombstone recites the facts of his birth; his death; and his
  brief history。  With the assistance of his descendants; we are now
  enabled to add the following record of the life and labours of this
  remarkable but almost forgotten man。
  Benjamin Huntsman was born in Lincolnshire in the year 1704。  His
  parents were of German extraction; and had settled in this country
  only a few years previous to his birth。  The boy being of an ingenious
  turn; was bred to a mechanical calling; and becoming celebrated for
  his expertness in repairing clocks; he eventually set up in business
  as a clock maker and mender in the town of Doncaster。  He also
  undertook various other kinds of metal work; such as the making and
  repairing of locks; smoke…jacks; roasting…jacks; and other articles
  requiring mechanical skill。  He was remarkably shrewd; observant;
  thoughtful; and practical; so much so that he came to be regarded as
  the 〃wise man〃 of his neighbourhood; and was not only consult
