  citoyen!〃  Scowling looks were turned upon him; and he deemed it
  expedient to take the first opportunity of escaping from the house;
  which he did by a back…door; and made the best of his way to
  Hacqueville。  From thence he went to Rouen; and succeeded in finding a
  passage on board an American ship; in which he sailed for New York;
  having first pledged his affections to an English girl; Sophia
  Kingdom; whom he had accidentally met at the house of Mr。 Carpentier;
  the American consul at Rouen。
  Arrived in America; he succeeded in finding employment as assistant
  surveyor of a tract of land along the Black River; near Lake Ontario。
  In the intervals of his labours he made occasional visits to New
  York; and it was there that the first idea of his block…machinery
  occurred to him。  He carried his idea back with him into the woods;
  where it often mingled with his thoughts of Sophia Kingdom; by this
  time safe in England after passing through the horrors of a French
  prison。  〃My first thought of the block…machinery;〃 he once said; 〃was
  at a dinner party at Major…General Hamilton's; in New York; my second
  under an American tree; when; one day that I was carving letters on
  its bark; the turn of one of them reminded me of it; and I thought;
  'Ah! my block! so it must be。' And what do you think。  were the
  letters I was cutting? Of course none other than S。  K。〃  Brunel
  subsequently obtained some employment as an architect in New York;
  and promulgated various plans for improving the navigation of the
  principal rivers。  Among the designs of his which were carried out;
  was that of the Park Theatre at New York; and a cannon foundry; in
  which he introduced improvements in casting and boring big guns。  But
  being badly paid for his work; and a powerful attraction drawing him
  constantly towards England; he determined to take final leave of
  America; which he did in 1799; and landed at Falmouth in the
  following March。  There he again met Miss Kingdom; who had remained
  faithful to him during his six long years of exile; and the pair were
  shortly after united for life。
  Brunel was a prolific inventor。  During his residence in America; he
  had planned many contrivances in his mind; which he now proceeded to
  work out。  The first was a duplicate writing and drawing machine;
  which he patented。  The next was a machine for twisting cotton thread
  and forming it into balls; but omitting to protect it by a patent; he
  derived no benefit from the invention; though it shortly came into
  very general use。  He then invented a machine for trimmings and
  borders for muslins; lawns; and cambrics;of the nature of a sewing
  machine。  His famous block…machinery formed the subject of his next
  patent。
  It may be explained that the making of the blocks employed in the
  rigging of ships for raising and lowering the sails; masts; and
  yards; was then a highly important branch of manufacture。  Some idea
  may be formed of the number used in the Royal Navy alone; from the
  fact that a 74…gun ship required to be provided with no fewer than
  1400 blocks of various sizes。  The sheaved blocks used for the running
  rigging consisted of the shell; the sheaves; which revolved within
  the shell; and the pins which fastened them together。  The fabrication
  of these articles; though apparently simple; was in reality attended
  with much difficulty。  Every part had to be fashioned with great
  accuracy and precision to ensure the easy working of the block when
  put together; as any hitch in the raising or lowering of the sails
  might; on certain emergencies; occasion a serious disaster。  Indeed;
  it became clear that mere hand…work was not to be relied on in the
  manufacture of these articles; and efforts were early made to produce
  them by means of machinery of the most perfect kind that could be
  devised。  In 1781; Mr。 Taylor; of Southampton; set up a large
  establishment on the river Itchen for their manufacture; and on the
  expiry of his contract; the Government determined to establish works
  of their own in Portsmouth Dockyard; for the purpose at the same time
  of securing greater economy; and of being independent of individual
  makers in the supply of an article of such importance in the
  equipment of ships。
  Sir Samuel Bentham; who then filled the office of Inspector…General
  of Naval Works; was a highly ingenious person; and had for some years
  been applying his mind to the invention of improved machinery for
  working in wood。  He had succeeded in introducing into the royal
  dockyards sawing…machines and planing…machines of a superior kind; as
  well as block…making machines。  Thus the specification of one of his
  patents; taken out in 1793; clearly describes a machine for shaping
  the shells of the blocks; in a manner similar to that afterwards
  specified by Brunel。  Bentham had even proceeded with the erection of
  a building in Portsmouth Dockyard for the manufacture of the blocks
  after his method; the necessary steam…engine being already provided;
  but with a singular degree of candour and generosity; on Brunel's
  method being submitted to him; Sir Samuel at once acknowledged its
  superiority to his own; and promised to recommend its adoption by the
  authorities in his department。
  The circumstance of Mrs。 Brunel's brother being Under…Secretary to
  the Navy Board at the time; probably led Brunel in the first instance
  to offer his invention to the Admiralty。  A great deal; however;
  remained to be done before he could bring his ideas of the
  block…machinery into a definite shape; for there is usually a wide
  interval between the first conception of an intricate machine and its
  practical realization。  Though Brunel had a good knowledge of
  mechanics; and was able to master the intricacies of any machine; he
  laboured under the disadvantage of not being a practical mechanic and
  it is probable that but for the help of someone possessed of this
  important qualification; his invention; ingenious and important
  though it was; would have borne no practical fruits。  It was at this
  juncture that he was so fortunate as to be introduced to Henry
  Maudslay; the inventor of the sliderest。
  It happened that a M。 de Bacquancourt; one of the French emigres;
  of whom there were then so many in London; was accustomed almost
  daily to pass Maudslay's little shop in Wells…street; and being
  himself an amateur turner; he curiously inspected the articles from
  time to time exhibited in the window of the young mechanic。  One day a
  more than ordinarily nice piece of screw…cutting made its appearance;
  on which he entered the shop to make inquiries as to the method by
  which it had been executed。  He had a long conversation with Maudslay;
  with whom he was greatly pleased; and he was afterwards accustomed to
  look in upon him occasionally to see what new work was going on。
  Bacquancourt was also on intimate terms with Brunel; who communicated
  to him the difficulty he had experienced in finding a mechanic of
  sufficient dexterity to execute his design of the block…making
  machinery。  It immediately occurred to the former that Henry Maudslay
  was the very man to execute work of the elaborate character proposed;
  and he described to Brunel the new and beautiful tools which Maudslay
  had contrived for the purpose of ensuring accuracy and finish。  Brunel
  at once determined to call upon Maudslay; and it was arranged that
  Bacquancourt should introduce him; which he did; and after the
  interview which took place Brunel promised to call again with the
  drawings of his proposed model。
  A few days passed; and Brunel called with the first drawing; done by
  himself; for he was a capital draughtsman; and used to speak of
  drawing as the 〃alphabet of the engineer。〃  The drawing only showed a
  little bit of the intended machine; and Brunel did not yet think it
  advisable to communicate to Maudslay the precise object he had in
  view; for inventors are usually very chary of explaining their
  schemes to others; for fear of being anticipated。  Again Brunel
  appeared at Maudslay's shop with a further drawing; still not
  explaining his design; but at the third visit; immediately on looking
  at the fresh drawings he had brought; Maudslay exclaimed; 〃Ah! now I
  see what you are thinking of; you want machinery for making blocks。〃
  At this Brunel became more communicative; and explained his designs
  to the mechanic; who fully entered into his views; and went on from
  that time forward striving to his utmost to work out the inventor's
  conceptions and embody them in a practical machine。
  While still occupied on the models; which were begun in 1800;
  Maudslay removed his shop from Wells…street; where he was assisted by
  a single journeyman; to Margaret…street; Cavendish…square; where he
  had greater room for carrying on his trade; and was also enabled to
  increase the number of his hands。  The working models were ready for
  inspection by Sir Samuel Bentham and the Lords of the Admiralty in
  1801; and having
