； in order to wheel them away to their place outside。 On the spur of the moment I said to Mr。 Maudslay； 〃If you would only permit me to do such a job as that in your service； I should consider myself most fortunate！〃 I shall never forget the keen but kindly look that he gave me。 〃So ；〃 said he； 〃you are one of that sort； are you？〃 I was inwardly delighted at his words。
When our round of the works was concluded； I ventured to say to Mr。 Maudslay that 〃I had brought up with me from Edinburgh some working models of steam…engines and mechanical drawings； and I should feel truly obliged if he would allow me to show them to him？〃 〃By all means；〃 said he； 〃bring them to me tomorrow at twelve o'clock。〃 I need not say how much pleased I was at this permission to exhibit my handiwork； and how anxious I felt as to the result of Mr。 Maudslay's inspection of it。
I carefully unpacked my working model of the steam…engine at the carpenter's shop； and had it conveyed； together with my drawings； on a hand…cart to Mr。 Maudslay's next morning at the appointed hour。 I was allowed to place my work for his inspection in a room next his office and counting…house。 I then called at his residence close by； where he kindly received me in his library。 He asked me to wait until he and his partner； Joshua Field； had inspected my handiwork。
I waited anxiously。 Twenty long minutes passed。 At last he entered the room； and from a lively expression in his countenance I observed in a moment that the great object of my long cherished ambition had been attained！ He expressed； in good round terms； his satisfaction at my practical ability as a workman engineer and mechanical draughtsman。 Then； opening the door which led from his library into his beautiful private workshop； he said； 〃This is where I wish you to work； beside me； as my assistant workman。 From what I have seen there is no need of an apprenticeship in your case。〃
He then proceeded to show me the collection of exquisite tools of all sorts with which his private workshop was stored。 They mostly bore the impress of his own clearheadedness and common…sense。 They were very simple； and quite free from mere traditional forms and arrangements。 At the same time they were perfect for the special purposes for which they had been designed。 The workshop was surrounded with cabinets and drawers； filled with evidences of the master's skill and industry。 Every tool had a purpose。 It had been invented for some special reason。 Sometimes it struck the keynote； as it were； to many of the important contrivances which enable man to obtain a complete mastery over materials。
There were also hung upon the walls； or placed upon shelves； many treasured relics of the first embodiments of his constructive genius。 There were many models explaining； step by step； the gradual progress of his teeming inventions and contrivances。 The workshop was thus quite a historical museum of mechanism。 It exhibited his characteristic qualities in construction。 I afterwards found out that many of the contrivances preserved in his private workshop were treasured as suggestive of some interesting early passage in his useful and active life。 They were kept as relics of his progress towards mechanical perfection。 When he brought them out from time to time； to serve for the execution of some job in hand； he was sure to dilate upon the occasion that led to their production； as well as upon the happy results which had followed their general employment in mechanical engineering。
It was one of his favourite maxims； 〃First； get a clear notion of what you desire to accomplish； and then in all probability you will succeed in doing it。〃 Another was 〃Keep a sharp look…out upon your materials； get rid of every pound of material you can do without； put to yourself the question； 'What business has it to be there？ avoid complexities； and make everything as simple as possible。〃 Mr。 Maudslay was full of quaint maxims and remarks； the result of much shrewdness； keen
observation； and great experience。 They were well worthy of being stored up in the mind； like a set of proverbs； full of the life and experience of men。 His thoughts became compressed into pithy expressions exhibiting his force of character and intellect。 His quaint remarks on my first visit to his workshop； and on subsequent occasions； proved to me invaluable guides to 〃right thinking〃 in regard to all matters connected with mechanical structure。
Mr。 Maudslay seemed at once to take me into his confidence。 He treated me in the most kindly mannernot as a workman or an apprentice； but as a friend。 I was an anxious listener to everything that he said； and it gave him pleasure to observe that I understood and valued his conversation。 The greatest treat of all was in store for me。 He showed me his exquisite collection of taps and dies and screw…tackle； which he had made with the utmost care for his own service。 They rested in a succession of drawers near to the bench where he worked。 There was a place for every one； and every one was in its place。 There was a look of tidiness about the collection which was very characteristic of the man。 Order was one of the rules which he rigidly observed； and he endeavoured to enforce it upon all who were in his employment。
He proceeded to dilate upon the importance of the uniformity of screws。 Some may call it an improvement； but it might almost be called a revolution in mechanical engineering which Mr。 Maudslay introduced。 Before his time no system had been followed in proportioning the number of threads of screws to their diameter。 Every bolt and nut was thus a speciality in itself； and neither possessed nor admitted of any community with its neighbours。 To such an extent had this practice been carried that all bolts and their corresponding nuts had to be specially marked as belonging to each other。 Any intermixture that occurred between them led to endless trouble and expense； as well as inefficiency and confusion；especially when parts of complex machines had to be taken to pieces for repairs。
None but those who lived in the comparatively early days of machine manufacture can form an adequate idea of the annoyance； delay； and cost of this utter want of system； or can appreciate the vast services rendered to mechanical engineering by Mr。 Maudslay； who was the first to introduce the practical measures necessary for its remedy。 In his system of screw…cutting machinery； and in his taps and dies； and screw…tackle generally； he set the example； and in fact laid the foundation； of all that has since been done in this most essential branch of machine construction。 Those who have had the good fortune to work under him； and have experienced the benefits of his practice； have eagerly and ably followed him； and thus his admirable system has become established throughout the entire mechanical world。
Mr。 Maudslay kept me with him for about three hours； initiating me into his system。 It was with the greatest delight that I listened to his wise instruction。 The sight of his excellent tools； which he showed me one by one； filled me with an almost painful feeling of earnest hope that I might be able in any degree to practically express how thankful I was to be admitted to so invaluable a privilege as to be in close communication with this great master in all that was most perfect in practical mechanics。
When he concluded his exposition； he told me in the most kindly manner that it would be well for me to take advantage of my father's presence in London to obtain some general knowledge of the metropolis； to see the most remarkable buildings； and to obtain an introduction to some of my father's friends。 He gave me a week for this purpose； and said he should be glad to see me at his workshop on the following Monday week。
It singularly happened that on the first day my father went out with me； he encountered an old friend。 He had first known him at Mr。 Miller's of Dalswinton； when the first steamboat was tried； and afterwards at Edinburgh while he was walking the courts as an advocate； or writing articles for the Edinburgh Review。 This was no other than Henry Brougham。 He was descending the steps leading into St。 James's Park； fro
