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 manner--not 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, from the place where the Duke of York's monument now stands. Brougham immediately recognised my father. There was a hearty shaking of hands, and many inquiries on either side. "And what brings you to London now?" asked Brougham. My father told him that it was about his son here, who had obtained an important position at Maudslay's the engineer.

"If I can do anything for you," said Brougham, addressing me, "let me know. It will afford me much pleasure to give you introductions to men of science in London." I ventured to say that "Of all the men of science in London that I most wished to see, was Mr. Faraday of the Royal Institution." " Well," said Brougham, "I will send you a letter of introduction. We then parted.

My father availed himself of the opportunity of introducing me to several of his brother artists. We first went to the house of David Wilkie, in Church Street, Kensington. We found him at home, and he received us most kindly. We next visited Clarkson Stanfield, David Roberts, and some other artists. They were much attached to my father, and had, in the early part of their career, received much kindness from him while living in Edinburgh. They all expressed the desire that I should visit them frequently. I had thus the privilege of entree to a number of pleasant and happy homes, and my visits to them while in London was one of my principal sources of enjoyment.

On returning home to our lodgings that evening we found a note from Brougham, enclosing letters of introduction to Faraday and other scientific men; and stating that if at any time he could be of service to me he hoped that I would at once make use of him. My father was truly gratified with the substantial evidence of Brougham's kindly remembrance of him; and I? how could I be grateful enough? not only for my father's never-failing attention to my growth in knowledge and wisdom, but to his ever-willing readiness to help me onward in the path of scientific working and mechanical engineering. And now I was fortunate in another respect, in being admitted to the school, and I may say the friendship, of the admirable Henry Maudslay. Everything now depended upon myself, and whether I was worthy of all these advantages or not.

One of the days of this most interesting and memorable week was devoted to accompanying Mr. Maudslay in a visit to Somerset House. In the Admiralty Museum, then occupying a portion of the building, was a complete set of the working models of the celebrated block-making machinery. Most of these were the result of Maudslay's own skilful handiwork. He also designed, for the most part, this wonderful and complete series of machines. Sir Samuel Bentham and Mr. Brunel had given the idea, and Maudslay realised it in all its mechanical details. These working models contained the prototypes of nearly all the modern engineer tools which have given us so complete mastery over materials, and done so much for the age we live in.

It added no little to the enjoyment of this visit to hear Mr. Maudslay narrate, in his quaint and graphic language, the difficulties he had to encounter in solving so many mechanical problems. It occupied him nearly six years to design and complete these working models. They were forty-four in number--all masterly pieces of workmanship. To describe them was to him like living over again the most interesting and eventful part of his life. And no doubt the experience which he had thus obtained formed the foundation of his engineering fortunes.

Mr. Maudslay next conducted us to the Royal Mint on Tower Hill. Here we saw many of his admirable machines at work. He had a happy knack, in his contrivances and inventions, of making "short cuts" to the object in view. He avoided complexities, did away with roundabout processes, however ingenious, and went direct to his point. "Simplicity" was his maxim in every mechanical contrivance. His mastermind enabled him to see through and attain the end he sought by the simplest possible means. The reputation which he had acquired by his minting machinery enabled him to supply it in its improved form to the principal Governments of the world.

Some of the other days of the week were occupied by my father in attending to his own professional affairs, more particularly in connection with the Earl of Cassilis--whose noble mansion in London, and whose castle at Colzean, on the coast of Ayrshire, contain some of my father's finest works. The last day was most enjoyable. Mr. Maudslay invited my father, my brother Patrick, and myself, to accompany him in his beautiful small steam yacht, the Endeavour, from Westminster to Richmond Bridge, and afterwards to dine with him at the Star and Garter. I must first, however, say something of the origin of the Endeavour.

Mr. Maudslay's son, Joseph, inherited much of his father's constructive genius. He had made a beautiful arrangement of William Murdoch's original invention of the vibrating cylinder steam-engine, and adapted it for the working of paddle-wheel steamers. He first tried the action of the arrangement in a large working model, and its use was found to be in every respect satisfactory. Mr. Maudslay resolved to give his son's design a full-sized trial. He had a combined pair of vibrating engines constructed, of upwards of 20 horse-power, which were placed in a beautiful small steam vessel, appropriately named the Endeavour. The result was perfectly successful. The steamer became a universal favourite. It was used to convey passengers and pleasure parties from Blackfriars Bridge to Richmond. Eventually it became the pioneer of a vast progeny of vessels propelled by similar engines, which still crowd the Thames. All these are the legitimate descendants of the bright and active little Endeavour.

To return to my trip to Richmond. We got on board the boat on the forenoon of May the 29th. It was one of the most beautiful days of the year. The spring was at its loveliest. The bright fresh green of the trees was delightful. I shall never forget the pleasure with which I beheld, for the first time, the beautiful banks of the Thames. There was at that time a noble avenue of elm trees extending along the southern bank of the river, from Westminster Bridge to Lambeth Palace; while, on the northern side, many equally fine trees added picturesque grace to the then Houses of Parliament, while behind them were seen the great roof of Westminster Hall and the noble towers of Westminster Abbey. As we sped along we admired the ancient cedars, which gave dignity to the Bishop's grounds, on the one side, and the elms, laburnums, and lilacs, then in full bloom, which partially shaded the quaint old mansions of Cheyne Row, on the other. Alas! the march of improvement and the inevitable extension of the metropolis is rapidly destroying these vestiges of the olden time.

The beautiful views that came into sight, as we glided up the river, kept my father and my brother in a state of constant excitement. There were so many truly picturesque and paintable objects. Patrick's deft pencil was constantly at work, taking graphic notes of "glorious bits" Dilapidated farm-buildings, old windmills, pollarded willows, were rapidly noted, to be afterwards revisited and made immortal by his brush. There were also the fine mansions and cosy villas, partially shrouded by glorious trees, with their bright velvety lawns sloping down towards the river; not forgetting the delicate streams of thin blue smoke rising lazily through the trees in the tranquil summer air, and reminding one of the hospitable preparations then in progress.

We landed at Richmond Bridge, and walked up past the quaint old-fashioned mansions which gave so distinct a character to Richmond at that time. We then passed on to the celebrated Richmond Terrace, at the top of the hill, from which so glorious a view of the windings of the Thames is seen, with the luxuriant happy-looking landscape around. The enjoyment of this glorious day now reached its climax. We dined in the great dining-room, from the large windows of which we observed a view almost unmatched in the world, with the great tower of Windsor in the distance. I need not speak of the entertainment, which was everything that the kindest and most genial hospitality could offer. After a pleasant stroll in the Park, amidst the noble and venerable oak trees, which give such a dignity to the place, and after another visit to the Terrace, where we saw the sun set in a blaze of glory beyond the distant scenery, we strolled down the hill to the steamer, and descended the Thames in the cool of the summer evening.

I must not, however, omit to mention the lodgings taken for me by my father before he left London. It was necessary that they should be near Maudslay's works for the convenience of going and coming. We therefore looked about in the neighbourhood of Waterloo Road. One of the houses we visited was situated immediately behind the Surrey theatre. It seemed a very nice tidy house, and my father seemed to have taken a liking for it. But when we were introduced into the room where I was to sleep, he observed an ultra-gay bonnet lying on the bed, with flashy bright ribbons hanging from it. This sight seemed to alter his ideas, and he did not take the lodgings; but took another where there was no such bonnet.

I have no doubt about what passed through his mind at the time. We were in the neighbourhood of the theatre. There was evidently some gay young woman about the house. He thought the position might be dangerous for his son. I afterwards asked him why we had not taken that nice lodging. "Well," he said, "did not you see that ultra-gay bonnet lying on the bed? I think that looks rather suspicious!" Afterwards he added, "At all events, James, you will find that though there are many dirty roads in life, if you use your judgment you may always be able to find a clean crossing!" And so the good man left me. After an affectionate parting he returned to Edinburgh, and I remained in London to work out the plan of my life.

CHAPTER 8. Maudslay's Private Assistant

On the morning of Monday, the 30th of May 1829, I commenced my regular attendance at Mr. Maudslay's workshop. My first job was to assist him in making some modifications in the details of a machine which he had contrived some years before for generating original screws. I use the word "generating" as being most appropriate to express the objects and results of one of Mr. Maudslay's most original inventions.
