  The present Messrs。 Fox of Derby; who continue to carry on the
  business of the firm; claim for their grandfather; its founder; that
  he made the first planing machine in 1814;*

  Engineer; Oct。 10th; 1862。

  and they add that the original article continued in use until quite
  recently。  We have been furnished by Samuel Hall; formerly a workman
  at the Messrs。 Fox's; with the following description of the
  machine:   〃 It was essentially the same in principle as the planing
  machine now in general use; although differing in detail。  It had a
  self…acting ratchet motion for moving the slides of a compound slide
  rest; and a self…acting reversing tackle; consisting of three bevel
  wheels; one a stud; one loose on the driving shaft; and another on a
  socket; with a pinion on the opposite end of the driving shaft
  running on the socket。  The other end was the place for the driving
  pulley。  A clutch box was placed between the two opposite wheels;
  which was made to slide on a feather; so that by means of another
  shaft containing levers and a tumbling ball; the box on reversing was
  carried from one bevel wheel to the opposite one。〃  The same James Fox
  is also said at a very early period to have invented a screw…cutting
  machine; an engine for accurately dividing and cutting the teeth of
  wheels; and a self…acting lathe。  But the evidence as to the dates at
  which these several inventions are said to have been made is so
  conflicting that it is impossible to decide with whom the merit of
  making them really rests。  The same idea is found floating at the same
  time in many minds; the like necessity pressing upon all; and the
  process of invention takes place in like manner:  hence the
  contemporaneousness of so many inventions; and the disputes that
  arise respecting them; as described in a previous chapter。
  There are still other claimants for the merit of having invented the
  planing machine; among whom may be mentioned more particularly
  Matthew Murray of Leeds; and Richard Roberts of Manchester。  We are
  informed by Mr。 March; the present mayor of Leeds; head of the
  celebrated tool…manufacturing firm of that town; that when he first
  went to work at Matthew Murray's; in 1814; a planing machine of his
  invention was used to plane the circular part or back of the D valve;
  which he had by that time introduced in the steam…engine。  Mr。 March
  says; 〃I recollect it very distinctly; and even the sort of framing
  on which it stood。  The machine was not patented; and like many
  inventions in those days; it was kept as much a secret as possible;
  being locked up in a small room by itself; to which the ordinary
  workmen could not obtain access。  The year in which I remember it
  being in use was; so far as I am aware; long before any
  planing…machine of a similar kind had been invented。〃
  Matthew Murray was born at Stockton…on…Tees in the year 1763。  His
  parents were of the working class; and Matthew; like the other
  members of the family; was brought up with the ordinary career of
  labour before him。  When of due age his father apprenticed him to the
  trade of a blacksmith; in which he very soon acquired considerable
  expertness。  He married before his term had expired; after which;
  trade being slack at Stockton; he found it necessary to look for work
  elsewhere。  Leaving his wife behind him; he set out for Leeds with his
  bundle on his back; and after a long journey on foot; he reached that
  town with not enough money left in his pocket to pay for a bed at the
  Bay Horse inn; where he put up。  But telling the landlord that he
  expected work at Marshall's; and seeming to be a respectable young
  man; the landlord trusted him; and he was so fortunate as to obtain
  the job which he sought at Mr。 Marshall's; who was then beginning the
  manufacture of flax; for which the firm has since become so famous。
  Mr。 Marshall was at that time engaged in improving the method of
  manufacture;*
  'footnote。。。
  We are informed in Mr。 Longstaffe's Annals and Characteristics of
  Darlington; that the spinning of flax by machinery was first begun by
  one John Kendrew; an ingenious self…taught mechanic of that town; who
  invented a machine for the purpose; for which he took out a patent in
  1787。  Mr。 Marshall went over from Leeds to see his machine; and
  agreed to give him so much per spindle for the right to use it。  But
  ceasing to pay the patent right; Kendrew commenced an action against
  him for a sum of nine hundred pounds alleged to be due under the
  agreement。  The claim was disputed; and Kendrew lost his action; and
  it is added in Longstaffe's Annals; that even had he succeeded; it
  would have been of no use; for Mr。 Marshall declared that he had not
  then the money wherewith to pay him。  It is possible that Matthew
  Murray may have obtained some experience of flax…machinery in working
  for Kendrew; which afterwards proved of use to him in Mr。 Marshall's
  establishment。
  。。。'
  and the young blacksmith was so fortunate or rather so dexterous as
  to be able to suggest several improvements in the machinery which
  secured the approval of his employer; who made him a present of 20L。;
  and very shortly promoted him to be the first mechanic in the
  workshop。  On this stroke of good fortune Murray took a house at the
  neighbouring village of Beeston; sent to Stockton for his wife; who
  speedily joined him; and he now felt himself fairly started in the
  world。  He remained with Mr。 Marshall for about twelve years; during
  which he introduced numerous improvements in the machinery for
  spinning flax; and obtained the reputation of being a first…rate
  mechanic。  This induced Mr。 James Fenton and Mr。 David Wood to offer
  to join him in the establishment of an engineering and machine…making
  factory at Leeds; which he agreed to; and operations were commenced
  at Holbeck in the year 1795。
  As Mr。 Murray had obtained considerable practical knowledge of the
  steam…engine while working at Mr。 Marshall's; he took principal
  charge of the engine…building department; while his partner Wood
  directed the machine…making。  In the branch of engine…building Mr。
  Murray very shortly established a high reputation; treading close
  upon the heels of Boulton and Wattso close; indeed; that that firm
  became very jealous of him; and purchased a large piece of ground
  close to his works with the object of preventing their extension。*
  'footnote。。。
  The purchase of this large piece of ground; known as Camp Field; had
  the effect of 〃plugging up〃 Matthew Murray for a time; and it
  remained disused; except for the deposit of dead dogs and other
  rubbish; for more than half a century。  It has only been enclosed
  during the present year; and now forms part of the works of Messrs。
  Smith; Beacock; and Tannet; the eminent tool…makers。

  His additions to the steam…engine were of great practical value; one
  of which; the self…acting apparatus attached to the boiler for the
  purpose of regulating the intensity of fire under it; and
  consequently the production of steam; is still in general use。  This
  was invented by him as early as 1799。  He also subsequently invented
  the D slide valve; or at least greatly improved it; while he added to
  the power of the air…pump; and gave a new arrangement to the other
  parts; with a view to the simplification of the powers of the engine。
  To make the D valve work efficiently; it was found necessary to form
  two perfectly plane surfaces; to produce which he invented his
  planing machine。  He was also the first to adopt the practice of
  placing the piston in a horizontal position in the common condensing
  engine。  Among his other modifications in the steam…engine; was his
  improvement of the locomotive as invented by Trevithick; and it ought
  to be remembered to his honour that he made the first locomotive that
  regularly worked upon any railway。
  This was the engine erected by him for Blenkinsop; to work the
  Middleton colliery railway near Leeds; on which it began to run in
  1812; and continued in regular use for many years。  In this engine he
  introduced the double cylinderTrevithick's engine being provided
  with only one cylinder; the defects of which were supplemented by the
  addition of a fly…wheel to carry the crank over the dead points。
  But Matthew Murray's most important inventions; considered in their
  effects on manufacturing industry; were those connected with the
  machinery for heckling and spinning flax; which he very greatly
  improved。  His heckling machine obtained for him the prize of the gold
  medal of the Society of Arts; and this as well as his machine for wet
  flax…spinning by means of sponge weights proved of the greatest
  practical value。  At the time when these inventions were made the flax
  trade was on the point of expiring; the spinners being unable to
  produce yarn to a profit; and their almost immediate effect was to
  reduce the cost of production; to improve immensely the quality of
  the manufacture;
