In all these matters, my early instructor, Johnie Syme, gave me such information as proved of the greatest use to me in the after progress of my mechanical career. Johnie Syme was also the very incarnation of quaint sly humour; and when communicating some of his most valued arcana of practical mechanical knowledge he always reminded me of some of Ostade's Dutchmen, by an almost indescribable sly humorous twinkle of the eye, which in that droll way stamped his information on my memory.

Tom Smith was another of my attached cronies. Our friendship began at the High School in 1818. Our similarity of disposition bound us together. Smith was the son of an enterprising general merchant at Leith. His father had a special genius for practical chemistry. He had established an extensive colour manufactory at Portobello, near Edinburgh, where he produced white lead, red lead, and a great variety of colours—in the preparation of which he required a thorough knowledge of chemistry.Tom Smith inherited his father's tastes, and admitted me to share in his experiments, which were carried on in a chemical laboratory situated behind his father's house at the bottom of Leith Walk.

We had a special means of communication. When anything particular was going on at the laboratory, Tom hoisted a white flag on the top of a high pole in his father's garden. Though I was more than a mile apart, I kept a look-out in the direction of the laboratory with a spy-glass. My father's house was at the top of Leith Walk, and Smith's house was at the bottom of it. When the flag was hoisted I could clearly see the invitation to me to "come down." I was only too glad to run down the Walk and join my chum, and take part with him in some interesting chemical process. Mr. Smith, the father, made me heartily welcome. He was pleased to see his son so much attached to me, and he perhaps believed that I was worthy of his friendship. We took zealous part in all the chemical proceedings, and in that way Tom was fitting himself for the business of his life.

Mr. Smith was a most genial tempered man. He was shrewd and quick-witted, like a native of York, as he was. I received the greatest kindness from him as well as from his family. His house was like a museum. It was full of cabinets, in which were placed choice and interesting objects in natural history, geology, mineralogy, and metallurgy. All were represented. Many of these specimens had been brought to him from abroad by his ship captains who transported his colour manufactures and other commodities to foreign parts.

My friend Tom Smith and I made it a rule—and in this we were encouraged by his father—that, so far as was possible, we ourselves should actually make the acids and other substances used in our experiments. We were not to buy them ready made, as this would have taken the zest out of our enjoyment. We should have lost the pleasure and instruction of producing them by aid of our own wits and energies. To encounter and overcome a difficulty is the most interesting of all things. Hence, though often baffled, we eventually produced perfect specimens of nitrous, nitric, and muriatic acids. We distilled alcohol from duly fermented sugar and water, and rectified the resultant spirit from fusel oil by passing the alcoholic vapour through animal charcoal before it entered the worm of the still. We converted part of the alcohol into sulphuric ether. We produced phosphorus from bones, and elaborated many of the mysteries of chemistry.

The amount of practical information which we obtained by this system of making our own chemical agents was such as to reward us, in many respects, for the labour we underwent. To outsiders it might appear a very troublesome and roundabout way of getting at the finally desired result. But I feel certain that there is no better method of rooting chemical or any other instruction, deeply in our minds. Indeed, I regret that the same system is not pursued by young men of the present day. They are seldom, if ever, called upon to exert their own wits and industry to obtain the requisites for their instruction. A great deal is now said about "technical education"; but how little there is of technical handiness or head work! Everything is bought ready made to their hands; and hence there is no call for individual ingenuity.

I often observe, in shop-windows, every detail of model ships and model steam-engines, supplied ready made for those who are "said to be" of an ingenious and mechanical turn. Thus the vital uses of resourcefulness are done away with, and a sham exhibition of mechanical genius is paraded before you by the young impostors—the result, for the most part, of too free a supply of pocket money. I have known too many instances of parents, led by such false evidence of constructive skill, apprenticing their sons to some engineering firm; and, after paying vast sums, finding out that the pretender comes out of the engineering shop with no other practical accomplishment than that of cigar-smoking!

The truth is that the eyes and the fingers—the bare fingers—are the two principal inlets to sound practical instruction. They are the chief sources of trustworthy knowledge as to all the materials and operations which the engineer has to deal with, No book knowledge can avail for that purpose. The nature and properties of the materials must come in through the finger ends. Hence, I have no faith in young engineers who are addicted to wearing gloves. Gloves, especially kid gloves, are perfect non-conductors of technical knowledge. This has really more to do with the efficiency of young aspirants for engineering success than most people are aware of!

CHAPTER 6. Mechanical Beginnings.

I left the High School at the end of 1820. I carried with me a small amount of Latin, and no Greek. I do not think I was much the better for my small acquaintance with the dead languages. I wanted something more living and quickening. I continued my studies at private classes. Arithmetic and geometry were my favourite branches.The three first books of Euclid were to me a new intellectual life. They brought out my power of reasoning. They trained me mentally. They enabled me to arrive at correct conclusions, and to acquire a knowledge of absolute truths. It is because of this that I have ever since held the beautifully perfect method of reasoning, as exhibited in the exact method of arriving at Q.E.D., to be one of the most satisfactory efforts and exercises of the human intellect.

Besides visiting and taking part in the works at Patterson's foundry, and joining in the chemical experiments at Smith's laboratory, my father gave me every opportunity for practising the art of drawing. He taught me to sketch with exactness every object, whether natural or artificial, so as to enable the hand to accurately reproduce what the eye had seen. In order to acquire this almost invaluable art, which can serve so many valuable purposes in life, he was careful to educate my eye, so that I might perceive the relative proportions of the objects placed before me. He would throw down at random a number of bricks, or pieces of wood representing them, and set me to copy their forms, their proportions, their lights and shadows respectively.

I have often heard him say that any one who could make a correct drawing in regard to outline, and also indicate by a few effective touches the variation of lights and shadows of such a group of model object's, might not despair of making a good and correct sketch of the exterior of York Minster!

My father was an enthusiast in praise of this graphic language, and I have followed his example. In fact, it formed a principal part of my own education. It gave me the power of recording observations with a few graphic strokes of the pencil, which far surpassed in expression any number of mere words. This graphic eloquence is one of the highest gifts in conveying clear and correct ideas as to the forms of objects—whether they be those of a simple and familiar kind, or of some form of mechanical construction, or of the details of fine building, or the characteristic features of a wide-stretching landscape. This accomplishment of accurate drawing, which I achieved for the most part in my father's work-room, served me many a good turn in future years with reference to the engineering work which became the business of my life.

I was constantly busy. Mind, hands, and body were kept in a state of delightful and instructive activity. When not drawing, I occupied myself in my father's workshop at the lathe, the furnace, or the bench. I gradually became initiated into every variety of mechanical and chemical manipulation. I made my own tools and constructed my chemical apparatus, as far as lay in my power. With respect to the latter, I constructed a very handy and effective blowpipe apparatus, consisting of a small air force-pump, connected with a cylindrical vessel of tin plate. By means of an occasional use of the handy pump, it yielded such a fine steady blowpipe blast, as enabled me to bend glass tubes and blow bulbs for thermometers, to analyse metals or mineral substances, or to do any other work for which intense heat was necessary. My natural aptitude for manipulation, whether in mechanical or chemical operations, proved very serviceable to myself as well as to others; and (as will be shown hereafter) it gained for me the friendship of many distinguished scientific men.

But I did not devote myself altogether to experiments. Exercise is as necessary for the body as the mind. Without full health a man cannot enjoy comfort, nor can he possess endurance. I therefore took plenty of exercise out of doors. I accompanied my father in his walks round Edinburgh. My intellect was kept alive during these delightful excursions. For sometimes my father was accompanied by brother-artists, whose conversation is always so attractive; and sometimes by scientific men, such as Sir James Hall, Professor Leslie, Dr. Brewster, and others. Whatever may have been my opportunities for education so-called, nothing could have better served the purpose of real education (the evolution of the mental faculties) than the opportunities I enjoyed while accompanying and listening to the conversation of men distinguished for their originality of thought and their high intellectual capacity. This was a mental culture of the best kind.

The volcanic origin of the beautiful scenery round Edinburgh was often the subject of their conversation. Probably few visitors are aware that all those remarkable eminences, which give to the city and its surroundings so peculiar and romantic an aspect, are the results of the operation, during inconceivably remote ages, of volcanic force penetrating the earth's crust by disruptive power, and pouring forth streams of molten lava, now shrunk and cooled into volcanic rock. The observant eye, opened by the light of Science, can see unmistakable evidences of a condition of things which were in action at periods so remote as, in comparison, to shrink up the oldest of human records into events of yesterday.

I had often the privilege of standing by and hearing the philosophic Leslie, Brewster, and Hall, discussing these volcanic remains in their actual presence; sometimes at Arthur's Seat or on the Calton Hill, or at the rock on which Edinburgh Castle stands, Their observations sank indelibly into my memory, and gave me the key to the origin of this grand class of terrestrial phenomena. When standing at the "Giant's Ribs," on the south side of Arthur's Seat, I felt as if one of the grandest pages of the earth's history lay open before me. The evidences of similar volcanic action abound in many other places near Edinburgh; and they may be traced right across Scotland from the Bass Rock to Fingal's Cave, the Giant's Causeway in Antrim, and Slievh League on the south-west coast of Donegal in Ireland.

Volcanic action, in some inconceivably remote period of the earth's crust history, has been the Plough, and after denudation by water, has been the Harrow, by which the originally deep-seated mineral treasures of the globe have been brought within the reach of man's industrial efforts. It has thus yielded him inexhaustible mineral harvests, and helped him to some of the most important material elements in his progress towards civilisation. It is from this consideration that, while enjoying the results of these grand fundamental actions of the Creator's mighty agencies in their picturesque aspect, the knowledge of their useful results to man adds vastly to the grandeur of the contemplation of their aspect and nature. This great subject caused me, even at this early period of my life, to behold with special interest the first peep at the structure of the moon's surface, as revealed to me by an excellent Ramsden "spy-glass," which my father possessed, and thus planted the seed of that earnest desire to scrutinise more minutely the moon's wonderful surface, which in after years I pursued by means of the powerful reflecting telescopes constructed by myself.

To turn to another subject. In 1822 the loyalty of Scotland was greatly excited when George the Fourth paid his well-known visit to Edinburgh. It was then the second greatest city in the kingdom, and had not been visited by royalty for about 170 years. The civic authorities, and the inhabitants generally, exerted themselves to the utmost to give the king a cordial welcome, in spite of a certain feeling of dissatisfaction as to his personal character. The recent trial and death of Queen Caroline had not been forgotten, yet all such recollections were suppressed in the earnest desire to show every respect to the royal visitor. Edinburgh was crowded with people from all parts of the country; heather was arrayed on every bonnet and hat; and the reception was on the whole magnificent. Perhaps the most impressive spectacle was the orderliness of the multitude, all arrayed in their Sunday clothes. The streets, windows; and house-tops were crowded; and the Calton Hill, Salisbury Crags, and even Arthur's Seat it self, were covered with people. On the night before the arrival a gigantic bonfire on Arthur's Seat lit up with a tremendous blaze the whole city, as well as the surrounding country. It formed a magnificent and picturesque sight, illuminating the adjacent mountains as well as the prominent features of the city. It made one imagine that the grand old volcanic mountain had once more, after a rest of some hundreds of thousands of years, burst out again in its former vehemence of eruptive activity.

There were, of course, many very distinguished men who took part in the pageant of the king's entry into Edinburgh, but none of them had their presence more cordially acknowledged than Sir Walter Scott, who never felt more proud of "his own romantic town" than he did upon this occasion. It is unnecessary to mention the many interesting features of the royal reception. The king's visit lasted for seven or eight days, and everything passed off loyally, orderly, happily, and successfully.

Shortly after this time there was a great deal of distress among the labouring classes. All the manufacturing towns were short of employment, and the weavers and factory workers were thrown upon the public. Many of the workmen thought that politics were the causes of their suffering. Radical clubs were formed, and the Glasgow weavers began to drill at nights in the hopes of setting things to rights by means of physical force. A large number of the starving weavers came to Edinburgh. A committee was formed, and contributions were collected, for the purpose of giving them temporary employment. They were set to work to make roads and walks round the Calton Hill and Crags. The fine walk immediately under the precipitous crags, which opens out such perfect panoramic views of Edinburgh, was made by these poor fellows. It was hard work for their delicate hands and fingers, which before had been accustomed only to deal with threads and soft fabrics. They were very badly suited for handling the mattock, shovel, and hand-barrow. The result of their labours, however, proved of great advantage to Edinburgh in opening up the beauties of its scenery. The road round the crags is still called "The Radical Road."

Let me here mention one of the most memorable incidents of the year 1824. I refer to the destructive fire which took place in the old town of Edinburgh. It broke out in an apartment situated in one of the highest piles of houses in the High Street. In spite of every effort of the firemen the entire pile was gutted and destroyed. The fire was thought to be effectually arrested; but towards the afternoon of the next day smoke was observed issuing from the upper part of the steeple of the Tron Church. The steeple was built of timber, covered with lead. There is never smoke but there is fire; and at last the flames burst forth. The height of the spire was so lofty that all attempts to extinguish the fire were hopeless. The lead was soon melted, and rushed in streams into the street below. At length the whole steeple fell down with a frightful crash.

I happened to see the first outbreak of this extraordinary fire, and I watched its progress to its close. Burning embers were carried by the wind and communicated the fire to neighbouring houses. The last outburst took place one night about ten. All the fire-engines of Edinburgh and the neighbourhood were collected round the buildings, and played water upon the flames, but without effect. Whole ranges of lofty old houses were roaring with fire. In the course of two or three hours, several acres, covered by the loftiest and most densely crowded houses in the High Street, were in a blaze. Some of them were of thirteen stories. Floor after floor came crashing down, throwing out a blaze of embers. The walls of each house acted as an enormous chimney —the windows acting as draught-holes. The walls, under the intense heat, were fluxed and melted into a sort of glass. The only method of stopping the progress of the fire was to pull down the neighbouring houses, so as to isolate the remaining parts of the High Street.

As the parapet of the grand old tower of the High Church, St. Giles, was near the site of the fire,—so near as to enable one to look down into it,—my father obtained permission to ascend, and I with him. When we emerged from the long dark spiral stairs on to the platform on the top of the tower, we found a select party of the most distinguished inhabitants looking down into the vast area of fire; and prominent among them was Sir Walter Scott. At last, after three days of tremendous efforts, the fire was subdued; but not till after a terrible destruction of property. The great height of the ruined remains of the piles of houses rendered it impossible to have them removed by the ordinary means. After several fruitless attempts with chains and ropes, worked by capstans, to pull them down, gunpowder was at last resorted to. Mines were dug under each vast pile; one or two barrels of gunpowder were placed into them and fired; and then the before solid masses came tumbling down amidst clouds of dust. The management of this hazardous but eventually safe process was conducted by Captain Basil Ball. He ordered a crew of sailors to be brought up from the man-of-war guardship in the Firth of Forth; and by their united efforts the destruction of the ruined walls was at last successfully accomplished.

In the autumn of 1823, when I was fifteen years old, I had a most delightful journey with my father. It was the first occasion on which I had been a considerable distance from home. And yet the journey was only to Stirling. My father had received a commission to paint a view of the castle as seen from the ruins of Cambuskenneth Abbey, situated a few miles from the town. We started from Newhaven by a small steamboat, passing, on our way up the Firth, Queensferry, Culross, and Alloa. We then entered the windings of the river, from which I saw the Ochils, a noble range of bright green mountains. The passage of the steamer through the turns and windings of the Forth was most interesting.

We arrived at Stirling, and at once proceeded to Cambuskenneth Abbey, where there was a noble old Gothic tower. This formed the foreground of my father's careful sketch, with Stirling Castle in the background, and Ben Lomond with many other of the Highland mountains in the distance. As my father wished to make a model of the Gothic tower, he desired me to draw it carefully, and to take the dimensions of all the chief parts as well as to make detailed sketches of its minor architectural features. It was a delightful autumn afternoon, and, before the day had closed, our work at the abbey was done. We returned to Stirling and took a walk round the castle to see the effect of the sun setting behind the Highland mountains.

Next morning we visited the castle. I was much interested with the interior, especially with a beautifully decorated Gothic oratory or private chapel, used by the Scottish kings when they resided at Stirling. The oratory had been converted with great taste into an ante-drawingroom of the governor's house. The exquisite decorations of this chapel* [footnote... This exquisite specimen of a carved oak Gothic apartment had a terrible incident in Scottish history connected with it. It was in this place that The Douglas intruded his presence on James the Third. He urged his demands in a violent and threatening manner, and afterwards laid hands upon the king. The latter, in defending himself with his dagger, wounded the Douglas mortally; and to get rid of the body the king cast it out of the window of the chapel, where it fell down the precipitous rock underneath. The chapel has since been destroyed by fire. ...] were the first specimens of Gothic carving in oak that I had ever seen, and they seemed to put our modern carvings to shame. The Great Hall, where the Scottish Parliament used to meet, was also very interesting as connected with the ancient history of the country.

From Stirling we walked to Alloa, passing the picturesque cascades rushing down the cleft's of the Ochils. We put up for the night at Clackmannan, a very decayed and melancholy-looking village, though it possessed a fine specimen of the Scottish castellated tower. It is said that Robert Bruce slept here before the Battle of Bannockburn. But the most interesting thing that I saw during the journey was the Devon Ironworks. I had read and heard about the processes carried on there in smelting iron ore and running it into pig-iron. The origin of the familiar trade term "pig-iron" is derived from the result of the arrangement most suitable for distributing the molten iron as it rushes forth from the opening made at the bottom part of the blast-furnace; when, after its reduction from the ore, it collects in a fluid mass of several tons weight. Previous to "tapping" the furnace a great central channel is made in the sand-covered floor of the forge; this central channel is then subdivided into many lateral branches or canals, into which the molten iron flows, and eventually hardens.

The great steam-engine that worked the blast furnace was the largest I had ever seen. A singular expedient was employed at these works, of using a vast vault hewn in the solid rock of the hillside for the purpose of storing up the blast produced by the engines, and so equalising the pressure; thus turning a mountain side into a reservoir for the use of a blast-furnace. This seemed to me a daring and wonderful engineering feat.

We waited at the works until the usual time had arrived for letting out the molten iron which had been accumulating at the lower part of the blast-furnace. It was a fine sight to see the stream of white-hot iron flowing like water into the large gutter immediately before the opening. From this the molten iron flowed on until it filled the moulds of sand which branched off from the central gutter. The iron left in the centre, when cooled and broken up, was called sow metal, while that in the branches was called pig iron; the terms being derived from the appearance of a sow engaged in its maternal duties. The pig-iron is thus cast in handy-sized pieces for the purpose of being transported to other iron foundries; while the clumsy sow metal is broken up and passes through another process of melting, or is reserved for foundry uses at the works where it is produced. After inspecting with great pleasure the machinery connected with the foundry, we took our leave and returned to Edinburgh by steamer from Alloa.

Shortly after, I had the good fortune to make the acquaintance of Robert Bald, the well-known mining engineer. He was one of the most kind-hearted men I have ever known. He was always ready to communicate his knowledge to young and old. His sound judgment and long practical experience in regard to coal-mining and the various machinery connected with it, rendered him a man of great importance in the northern counties, where his advice was eagerly sought for. Besides his special knowledge, he had a large acquaintance with literature and science. He was bright, lively, and energetic. He was a living record of good stories, and in every circle in which he moved he was the focus of cheerfulness. In fact, there was no greater social favourite in Edinburgh than Robert Bald.

Bald was very fond of young people, and he became much attached to me. He used to come to my father's house, and often came in to see what I was about in the work-room. He was rejoiced to see the earnest and industrious manner in which I was employed, in preparing myself for my proposed business as an engineer. He looked over my tools, mostly of my own making, and gave me every encouragement. When he had any visitors he usually brought them and introduced them to me. In this way I had the happiness to make the acquaintance of Robert Napier, Nelson, and Cook, of Glasgow; and in after life I continued to enjoy their friendship. It would be difficult for me to detail the acts of true disinterested kindness which I continued to receive from this admirable man.

On several occasions he wished me to accompany him on his business journeys, in order that I might see some works that would supply me with valuable information. He had designed a powerful pumping engine to drain more effectually a large colliery district situated near Bannockburn—close to the site of the great battle in the time of Robert the Bruce. He invited me to join him. It was with the greatest pleasure that I accepted his invitation; for there would be not only the pleasure of seeing a noble piece of steam machinery brought into action for the first time, but also the enjoyment of visiting the celebrated Carron Ironworks.

The Carron Ironworks are classic ground to engineers. They are associated with the memory of Roebuck, Watt, and Miller of Dalswinton. For there Roebuck and Watt began the first working steam-engine; Miller applied the steam-engine to the purposes of navigation, and invented the Carronade gun. The works existed at an early period in the history of British iron manufacture. Much of the machinery continued to be of wood. Although effective in a general way it was monstrously cumbrous. It gave the idea of vast power and capability of resistance, while it was far from being so in reality. It was, however, truly imposing and impressive in its effect upon strangers. When seen partially lit up by the glowing masses of white-hot iron, with only the rays of bright sunshine gleaming through a few holes in the roof, and the dark, black, smoky vaults in which the cumbrous machinery was heard rumbling away in the distance—while the moving parts were dimly seen through the murky atmosphere, mixed with the sounds of escaping steam and rushes of water; with the half-naked men darting about with masses of red-hot iron and ladles full of molten cast-iron—it made a powerful impression upon the mind.

I was afterwards greatly interested by a collection of old armour, dug up from the field of the Battle of Bannockburn close at hand. They were arranged on the walls of the house of the manager of the Carron Ironworks. There were swords, daggers, lances, battle-axes, shields, and coats of chain-armour. Some of the latter were whole, others in fragmentary portions. I was particularly interested with the admirable workmanship of the coats of mail. The iron links extended from the covering of the head to the end of the arms, and from the shoulders down to the hips, in one linked iron fabric. The beauty and exactness with which this chain-armour had been forged and built up were truly wonderful. There must have been "giants in those days." This grand style of armour was in use from the time of the Conquest, and was most effective in the way of protection, as it was fitted by its flexibility to give full play to the energetic action of the wearer. It was infinitely superior to the senseless plate-armour that was used, at a subsequent period, to encase soldiers like lobsters. The chain-armour I saw at Carron left a deep impression on my mind. I never see a bit of it, or of its representation in the figures on our grand tombs of the thirteenth century, but I think of my first sight of it at Carron and of the tremendous conflict at Bannockburn.

Remembering, also, the impressive sight of the picturesque fire-lit halls, and the terrible-looking, cumbrous machinery which I first beheld on a grand scale at Carron, I have often regretted that some of our artists do not follow up the example set them by that admirable painter, Wright of Derby, and treat us to the pictures of some of our great ironworks. They not only abound with the elements of the picturesque in its highest sense, but also set forth the glory of the useful arts in such a way as would worthily call forth the highest power of our artists.

To return to my life at Edinburgh. I was now seventeen years old. I had acquired a considerable amount of practical knowledge as to the use and handling of mechanical tools, and I desired to turn it to some account. I was able to construct working models of steam-engines and other apparatus required for the illustration of mechanical subjects. I began with making a small working steam engine for the purpose of grinding the oil-colours used by my father in his artistic work. The result was quite satisfactory. Many persons came to see my active little steam-engine at work, and they were so pleased with it that I received several orders for small workshop engines, and also for some models of steam-engines to illustrate the subjects taught at Mechanics' Institutions.

[Image] Sectional model of condensing steam-engine. By James Nasmyth

I contrived a sectional model of a complete condensing steam-engine of the beam and parallel motion construction. The model, as seen from one side, exhibited every external detail in full and due action when the flywheel was moved round by hand; while, on the other or sectional side, every detail of the interior was seen, with the steam-valves and air-pump, as well as the motion of the piston in the cylinder, with the construction of the piston and the stuffing box, together with the slide-valve and steam passages, all in due position and relative movement.

The first of these sectional models of the steam-engine was made for the Edinburgh School of Arts, where its uses in instructing mechanics and others in the application of steam were highly appreciated. The second was made for Professor Leslie, of the Edinburgh University, for use in his lectures on Natural Philosophy. The professor had, at his own private cost, provided a complete and excellent set of apparatus, which, for excellent workmanship and admirable utility, had never, I believe, been provided for the service of any university. He was so pleased with my addition to his class-room apparatus, that, besides expressing his great thanks for my services, he most handsomely presented me with a free ticket to his Natural Philosophy class as a regular student, so long as it suited me to make use of his instruction. But far beyond this, as a reward for my earnest endeavours to satisfy this truly great philosopher, was the kindly manner in which he on all occasions communicated to me conversationally his original and masterly views on the great fundamental principles of Natural Philosophy— especially as regarded the principles of Dynamics and the Philosophy of Mechanics. The clear views which he communicated in his conversation, as well as in his admirable lectures, vividly illustrated by the experiments which he had originated, proved of great advantage to me; and I had every reason to consider his friendship and his teaching as amongst the most important elements in my future success as a practical engineer.

Having referred to the Edinburgh School of Arts, I feel it necessary to say something about the origin of that excellent institution. A committee of the most distinguished citizens of Edinburgh was formed for the purpose of instituting a college in which working men and mechanics might possess the advantages of instruction in the principles on which their various occupations were conducted. Among the committee were Leonard Horner, Francis Jeffrey, Henry Cockburn, John Murray of Henderland, Alexander Bryson, James Mline, John Miller, the Lord Provost, and various members of the Council. Their efforts succeeded, and the institution was founded. The classes were opened in 1821, in which year I became a student.

In order to supply the students, who were chiefly young men of the working class, with sound instruction in the various branches of science, the lectures were delivered and the classes were superintended by men of established ability in their several departments. This course was regularly pursued from its fundamental and elementary principles to the highest point of scientific instruction. The consecutive lectures and examinations extended, as in the University, from October to May in each year's session. It was, in fact, our first technical college. In these later days when so many of our so-called Mechanics' Institutes are merely cheap reading-clubs for the middle classes, and the lectures are delivered for the most part merely for a pleasant evening' s amusement, it seems to me that we have greatly departed from the original design with which Mechanics' Institutions were founded.

As the Edinburgh School of Arts was intended for the benefit of mechanics, the lectures and classes were held in the evening after the day's work was over. The lectures on chemistry were given by Dr. Fyfe —an excellent man. His clearness of style, his successful experiments, and the careful and graphic method by which he carried his students from the first fundamental principles to the highest points of chemical science, attracted a crowded and attentive audience. Not less interesting were the lectures on Mechanical Philosophy, which in my time were delivered by Dr. Lees and Mr.Buchanan. The class of Geometry and Mathematics was equally well conducted, though the attendance was not so great.

The building which the directors had secured for the lecture-hall and class-rooms of the institution was situated at the lower end of Niddry Street, nearly under the great arch of the South Bridge. It had been built about a hundred years before, and was formerly used by an association of amateur musicians, who gave periodical concerts of vocal and instrumental music. The orchestra was now converted into a noble lecture table, with accommodation for any amount of apparatus that might be required for the purposes of illustration. The seats were arranged in the body of the hall in concentric segments, with the lecture table as their centre. In an alcove fight opposite the lecturer might often be seen the directors of the institution— Jeffrey, Horner, Murray, and others—who took every opportunity of dignifying by their presence this noble gathering of earnest and intelligent working men.

A library of scientific books was soon added to the institution, by purchases or by gifts. Such was the eagerness to have a chance of getting the book you wanted that I remember standing on many occasions for some time amidst a number of applicants awaiting the opening of the door on an evening library night. It was as crowded as if I had been standing at the gallery door of the theatre on a night when some distinguished star from London was about to make his appearance. There was the same eagerness to get a good place in the lecture-room, as near to the lecture table as possible, especially on the chemistry nights.

I continued my regular attendance at this admirable institution from 1821 to 1826. I am glad to find that it still continues in active operation. In November 1880 the number of students attending the Edinburgh School of Arts amounted to two thousand five hundred! I have been led to this prolix account of the beginning of the institution by the feeling that I owe a deep debt of gratitude to it, and because of the instructive and intellectually enjoyable evenings which I spent there, in fitting myself for entering upon the practical work of my life.

The successful establishment of the Edinburgh School of Arts had a considerable effect throughout the country. Similar institutions were established, lectures were delivered, and the necessary illustrations were acquired—above all, the working models of the steam-engine. There was quite a run upon me for supplying them. My third working model was made to the order of Robert Bald, for the purpose of being presented to the Alloa Mechanics' Institute; the fourth was manufactured for Mr. G. Buchanan, who lectured on mechanical subjects throughout the country; and the fifth was supplied to a Mr. Offley, an English gentleman who took a fancy for the model when he came to purchase some of my father's works.

The price I charged for my models was #10; and with the pecuniary results I made over one-third to my father, as a sort of help to remunerate him for my "keep," and with the rest I purchased tickets of admission to certain classes in the University. I attended the Chemistry course under Dr. Hope; the Geometry and Mathematical course under Professor Wallace; and the Natural Philosophy course under my valued friend and patron Professor Leslie. What with my attendance upon the classes, and my workshop and drawing occupations, my time did not hang at all heavy on my hands.

I got up early in the mornings to work at my father's lathe, and I sat up late at night to do the brass castings in my bedroom. Some of this, however, I did during the day-time, when not attending the University classes. The way in which I converted my bedroom into a brass foundry was as follows: I took up the carpet so that there might be nothing but the bare boards to be injured by the heat. My furnace in the grate was made of four plates of stout sheet-iron, lined with fire-brick, corner to corner. To get the requisite sharp draught I bricked up with single bricks the front of the fireplace, leaving a hole at the back of the furnace for the short pipe just to fit into. The fuel was generally gas coke and cinders saved from the kitchen. The heat I raised was superb—a white heat, sufficient to melt in a crucible six or eight pounds of brass.

Then I had a box of moulding sand, where the moulds were gently rammed in around the pattern previous to the casting. But how did I get my brass? All the old brassworks in my father's workshop drawers and boxes were laid under contribution. This brass being for the most part soft and yellow, I made it extra hard by the addition of a due proportion of tin. It was then capable of retaining a fine edge. When I had exhausted the stock of old brass, I had to buy old copper, or new, in the form of ingot or tile copper, and when melted I added to it one-eighth of its weight of pure tin, which yielded the strongest alloy of the two metals. When cast into any required form this was a treat to work, so sound and close was the grain, and so durable in resisting wear and tear. This is the true bronze or gun metal.

When melted, the liquid brass was let into the openings, until the whole of the moulds were filled. After the metal cooled it was taken out; and when the room was sorted up no one could have known that my foundry operations had been carried on in my bedroom. My brass foundry was right over my father's bedroom. He had forbidden me to work late at night, as I did occasionally on the sly. Sometimes when I ought to have been asleep I was detected by the sound of the ramming in of the sand of the moulding boxes. On such occasions my father let me know that I was disobeying his orders by rapping on the ceiling of his bedroom with a slight wooden rod of ten feet that he kept for measuring purposes. But I got over that difficulty by placing a bit of old carpet under my moulding boxes as a non-conductor of sound, so that no ramming could afterwards be heard. My dear mother also was afraid that I should damage my health by working so continuously. She would come into the workroom late in the evening, when I was working at the lathe or the vice, and say, "Ye'll kill yerself, laddie, by working so hard and so late". Yet she took a great pride in seeing me so busy and so happy.

Nearly the whole of my steam-engine models were made in my father's workroom. His foot-lathe and stove, together with my brass casting arrangements in my bedroom, answered all my purposes in the way of model making. But I had at times to avail myself of the smithy and foundry that my kind and worthy friend, George Douglass, had established in the neighbourhood. He had begun business as "a jobbing smith," but being a most intelligent and energetic workman, he shot ahead and laid the foundations of a large trade in steam-engines. When I had any part of a job in hand that was beyond the capabilities of my father's lathe, or my bedroom casting apparatus, I immediately went to Douglass's smithy, where every opportunity was afforded me for carrying on my larger class of work.

His place was only about five minutes' walk from my father's house. I had the use of his large turning-lathe, which was much more suitable for big or heavy work than the lathe at home. When any considerable bit of steel or iron forging had to be done, a forge fire and anvil were always placed at my service. In making my flywheels for the sectional models of steam-engines I had a rather neat and handy way of constructing them. The boss of the wheel of brass was nicely bored; the arm-holes were carefully drilled and taped, so as to allow the arms which I had turned to be screwed in and appear like neat columns of round wrought iron or steel screwed into the boss of the flywheel.

In return for the great kindness of George Douglass in allowing me to have the use of his foundry, I resolved to present him with a specimen of my handiwork. I desired to try my powers in making a more powerful steam-engine than I had as yet attempted to construct, in order to drive the large turning-lathe and the other tools and machinery of his small foundry. I accordingly set to work and constructed a direct-acting, high-pressure steam-engine, with a cylinder four inches in diameter. I use the term direct acting, because I dispensed with the beam and parallel motion, which was generally considered the correct mode of transferring the action of the piston to the crank.

The result of my labours was a very efficient steam-engine, which set all the lathes and mechanical tools in brisk activity of movement. It had such an enlivening effect upon the workmen that George Douglass afterwards told me that the busy hum of the wheels, and the active, smooth, rhythmic sound of the merry little engine had, through some sympathetic agency, so quickened the stroke of every hammer, chisel, and file in his workmen's hands, that it nearly doubled the output of work for the same wages!

The sympathy of activity acting upon the workmen's hands cannot be better illustrated than by a story told me by my father. A master tailor in a country town employed a number of workmen. They had been to see some tragic melodrama performed by some players in a booth at the fair. A very slow, doleful, but catching air was played, which so laid hold of the tailors' fancy that for some time after they were found slowly whistling or humming the doleful ditty, the movement of their needles keeping time to it; the result was that the clothing that should have been sent home on Saturday was not finished until the Wednesday following. The music had done it! The master tailor, being something of a philosopher, sent his men to the play again; but he arranged that they should be treated with lively merry airs. The result was that the lively airs displaced the doleful ditty; and the tailors' needles again reverted to even more than their accustomed quickness.

However true the story may be, it touches an important principle in regard to the stimulation of activity by the rapid movements or sounds of machinery, which influence every workman within their sight or hearing. We all know the influence of a quick merry air, played by fife and drum, upon the step and marching of a regiment of soldiers. It is the same with the quick movements of a steam-engine upon the activity of workmen.

I may add that my worthy friend, George Douglass, derived other advantages from the construction of my steam-engine. Being of an enterprising disposition he added another iron foundry to his smaller shops; he obtained many good engineering tools, and in course of time he began to make steam-engines for agricultural purposes. These were used in lieu of horse power for thrashing corn, and performing several operations that used to be done by hand labour in the farmyards. Orders came in rapidly, and before long the chimneys of Douglass's steam-engines were as familiar in the country round Edinburgh as corn stacks. All the large farms, especially in Midlothian and East Lothian, were supplied with his steam-engines. The business of George Douglass became very large; and in course of time he was enabled to retire with a considerable fortune.

In addition to the steam-engine which I presented to Douglass, I received an order to make another from a manufacturer of braiding. His machines had before been driven by hand labour; but as his business extended, the manufacturer employed me to furnish him with all engine of two-horse power, which was duly constructed and set to work, and gave him the highest satisfaction.

I may here mention that one of my earliest attempts at original contrivance was an Expansometer—an instrument for measuring in bulk all metals and solid substances. The object to be experimented on was introduced into a tube of brass, with as much water round it as to fill the tube. The apparatus was then plunged into a vessel of boiling water, or heated to boiling point; when the total expansion of the bar was measured by a graduated scale, as seen in the annexed engraving. By this simple means the expansion of any material might be ascertained under various increments of heat, say from 60deg to 2l2deg. It was simply a thermometer, the mass marking its own expansion. Dr. Brewster was so much pleased with the apparatus that he described it and figured it in the Edinburgh Philosophical Journal, of which he was then editor.

About the year 1827, when I was nineteen years old, the subject of steam carriages to run upon common roads occupied considerable attention. Several engineers and mechanical schemers had tried their hands, but as yet no substantial results had come of their attempts to solve the problem. Like others, I tried my hand. Having made a small working model of a steam-carriage, I exhibited it before the members of the Scottish Society of Arts. The performance of this active little machine was so gratifying to the Society that they requested me to construct one of such power as to enable four or six persons to be conveyed along the ordinary roads. The members of the Society, in their individual capacity, subscribed #60, which they placed in my hands as the means for carrying out their project.

I accordingly set to work at once. I had the heavy parts of the engine and carriage done at Anderson's foundry at Leith. There was in Anderson's employment a most able general mechanic named Robert Maclaughlan, who had served his time at Carmichaels' of Dundee. Anderson possessed some excellent tools, which enabled me to proceed rapidly with the work. Besides, he was most friendly, and took much delight in being concerned in my enterprise. This "big job" was executed in about four months. The steam-carriage was completed and exhibited before the members of the Society of Arts. Many successful trials were made with it on the queensferry Road, near Edinburgh. The runs were generally of four or five miles, with a load of eight passengers sitting on benches about three feet from the ground.

The experiments were continued for nearly three months, to the great satisfaction of the members. I may mention that in my steam-carriage I employed the waste steam to create a blast or draught by discharging it into the short chimney of the boiler at its lowest part, and found it most effective. I was not at that time aware that George Stephenson and others had adopted the same method; but it was afterwards gratifying to me to find that I had been correct as regards the important uses of the steam blast in the chimney. In fact, it is to this use of the waste steam that we owe the practical success of the locomotive-engine as a tractive power on railways, especially at high speeds.

The Society of Arts did not attach any commercial value to my steam road-carriage. It was merely as a matter of experiment that they had invited me to construct it. When it proved successful they made me a present of the entire apparatus. As I was anxious to get on with my studies, and to prepare for the work of practical engineering, I proceeded no further. I broke up the steam-carriage and sold the two small high-pressure engines, provided with a compact and strong boiler, for #67, a sum which more than defrayed all the expenses of the construction and working of the machine.

I still continued to make investigations as to the powers and capabilities of the steam-engine. There were numerous breweries, distilleries, and other establishments, near Edinburgh, where such engines were at work. As they were made by different engineers, I was desirous of seeing them and making sketches of them, especially when there was any special peculiarity in their construction. I found this a most favourite and instructive occupation. The engine tenters became very friendly with me, and they we re always glad to see me interested in them and their engines. They were especially delighted to see me make "drafts," as they called my sketches, of the engines under their charge.

My father sometimes feared that my too close and zealous application to engineering work might have a bad effect upon my health. My bedroom work at brass casting, my foundry work at the making of steam-engines, and my studies at the University classes, were perhaps too much for a lad of my age, just when I was in the hobbledehoy state—between a boy and a man. Whether his apprehensions were warranted or not, it did so happen that I was attacked with typhus fever in 1828, a disease that was then prevalent in Edinburgh. I had a narrow escape from its fatal influence. But thanks to my good constitution, and to careful nursing, I succeeded in throwing off the fever, and after due time recovered my usual health and strength.

In the course of my inspection of the engines made by different makers, I was impressed with the superiority of those made by the Carmichaels of Dundee. They were excellent both in design and in execution. I afterwards found that the Carmichaels were among the first of the Scottish engine makers who gave due attention to the employment of improved mechanical tools, with the object of producing accurate work with greater ease, rapidity, and economy, than could possibly be effected by the hand labour of even the most skilful workmen. I was told that the cause of the excellence of the Carmichaels' work was not only in the ability of the heads of the firm, but in their employment of the best engineers' tools. Some of their leading men had worked at Maudslay's machine shop in London, the fame of which had already reached Dundee; and Maudslay's system of employing machine tools had been imported into the northern steam factory.

I had on many occasions, when visiting the works where steam-engines were employed, heard of the name and fame of Maudslay. I was told that his works were the very centre and climax of all that was excellent in mechanical workmanship. These reports built up in my mind, at this early period of my aspirations, an earnest and hopeful desire that I might some day get a sight of Maudslay's celebrated works in London. In course of time it developed into a passion. I will now proceed to show how my inmost desires were satisfied.

CHAPTER 7. Henry Maudslay, London

The chief object of my ambition was now to be taken on at Henry Maudslay's works in London. I had heard so much of his engineering work, of his assortment of machine-making tools, and of the admirable organisation of his manufactory, that I longed to obtain employment there. I was willing to labour, in however humble a capacity, in that far-famed workshop.

I was aware that my father had not the means of paying the large premium required for placing me as an apprentice at Maudslay's works. I was also informed that Maudslay had ceased to take pupils. After experience, he found that the premium apprentices caused him much annoyance and irritation. They came in "gloves;" their attendance was irregular; they spread a bad example amongst the regular apprentices and workmen; and on the whole they were found to be very disturbing elements in the work of the factory.

It therefore occurred to me that, by showing some specimens of my work and drawings, I might be able to satisfy Mr. Maudslay that I was not an amateur, but a regular working engineer. With this object I set to work, and made with special care a most complete working model of a high-pressure engine. The cylinder was 2 inches diameter, and the stroke 6 inches. Every part of the engine, including the patterns, the castings, the forgings, were the results of my own individual handiwork. I turned out this sample of my ability as an engineer workman in such a style as even now I should be proud to own.

In like manner I executed several specimens of my ability as a mechanical draughtsman; for I knew that Maudslay would thoroughly understand my ability to work after a plan. Mechanical drawing is the alphabet of the engineer. Without this the workman is merely a "hand." With it he indicates the possession of "a head" I also made some samples of my skill in hand-sketching of machines, and parts of machines, in perspective—that is, as such objects really appear when set before us in their natural aspect. I was the more desirous of exhibiting the ability which I possessed in mechanical draughtsmanship, as I knew it to be a somewhat rare and much-valued acquirement. It was a branch of delineative art that my father had carefully taught me. Throughout my professional life I have found this art to be of the utmost practical value.

Having thus provided myself with such visible and tangible evidences of my capabilities as a young engineer, I carefully packed up my working model and drawings, and prepared to start for London. On the 19th of May 1829, accompanied by my father, I set sail by the Leith smack Edinburgh Castle, Captain Orr, master. After a pleasant voyage of four days we reached the mouth of the Thames. We sailed up from the Nore on Saturday afternoon, lifted up, as it were, by the tide, for it was almost a dead calm the whole way.

The sight of the banks of the famous river, with the Kent orchards in full blossom, and the frequent passages of steamers with bands of music and their decks crowded with pleasure-seekers, together with the sight of numbers of noble merchant ships in the river, formed a most glorious and exciting scene. It was also enhanced by the thought that I was nearing the great metropolis, around which so many bright but anxious hopes were centred, as the scene of my first important step into the anxious business of life, The tide, which had carried us up the river as far as Woolwich suddenly turned; and we remained there during the night. Early next morning the tide rose, and we sailed away again. It was a bright mild morning. The sun came "dancing up the east" as we floated past wharfs and woodyards and old houses on the banks, past wherries and coal boats and merchant ships on the river, until we reached our destination at the Irongate Wharf, near the Tower of London. I heard St. Paul's clock strike six just as we reached our mooring ground.

Captain Orr was kind enough to allow us to make the ship our hotel during the Sunday, as it was by no means convenient for us to remove our luggage on that day. My father took me ashore and we walked to Regent's Park. One of my sisters, who was visiting a friend in London, was residing in that neighbourhood. My father so planned his route as to include many of the most remarkable streets and buildings and sights of London. He pointed out the principal objects, and gave me much information about their origin and history.

I was much struck with the beautiful freshness and luxuriant growth of the trees and shrubs in the squares; for spring was then in its first beauty. The loveliness of Regent's Park surprised me. The extent of the space, the brilliancy of the fresh-leaved trees, and the handsome buildings by which the park was surrounded, made it seem to me more splendid than a picture from the Arabian Nights. Under the happy aspect of a brilliant May forenoon, this first long walk through London, with all its happy attendant circumstances, rendered it one of the most vividly remembered incidents in my life. After visiting my sister and giving her all the details of the last news from home, she joined us in our walk down to Westminster Abbey. The first view of the interior stands out in my memory as one of the most impressive sights I ever beheld. I had before read, over and over again, the beautiful description of the Abbey given by Washington Irving in the Sketch Book, one of the most masterly pieces of writing that I know of I now found one of my day-dreams realised.

We next proceeded over Westminster Bridge to call upon my brother Patrick. We found him surrounded by paintings from his beautiful sketches from Nature. Some of them were more or less advanced in the form of exquisite pictures, which now hang on many walls, and will long commemorate his artistic life. We closed this ever memorable day by dining at a tavern at the Surrey end of Waterloo Bridge. We sat at an upper window which commanded a long stretch of the river, and from which we could see the many remarkable buildings, from St. Paul's to Westminster Abbey and the Houses of Parliament, which lay on the other side of the Thames.

On the following day my father and I set out in search of lodgings, hotels being at that time beyond our economical method of living. We succeeded in securing a tidy lodging at No. 14 Agues Place, Waterloo Road. The locality had a special attraction for me, as it was not far from that focus of interest—Maudslay's factory. Our luggage was removed from the ship to the lodgings, and my ponderous cases, containing the examples of my skill as an engineer workman, were deposited in a carpenter's workshop close at hand.

I was now anxious for the interview with Maudslay. My father had been introduced to him by a mutual friend some two or three years before, and that was enough. On the morning of May the 26th we set out together, and reached his house in Westminster Road, Lambeth. It adjoined his factory. My father knocked at the door. My own heart beat fast. Would he be at home? Would he receive us? Yes! he was at home; and we were invited to enter.

Mr. Maudslay received us in the most kind and frank manner. After a little conversation my father explained the object of his visit. "My son," he said, pointing to me, "is very anxious to have the opportunity of acquiring a thorough practical knowledge of mechanical engineering, by serving as an apprentice in some such establishment as yours" "Well," replied Maudslay, "I must frankly confess to you that my experience of pupil apprentices has been so unsatisfactory that my partner and myself have determined to discontinue to receive them—no matter at what premium. This was a very painful blow to myself; for it seemed to put an end to my sanguine expectations.

Mr. Maudslay knew that my father was interested in all matters relating to mechanical engineering, and he courteously invited him to go round the works. Of course I accompanied them. The sight of the workshops astonished me. They excelled all that I had anticipated. The beautiful machine tools, the silent smooth whirl of the machinery, the active movements of the men, the excellent quality of the work in progress, and the admirable order and management that pervaded the whole establishment, rendered me more tremblingly anxious than ever to obtain some employment there, in however humble a capacity.

Mr. Maudslay observed the earnest interest which I and my father took in everything going on, and explained the movements of the machinery and the rationale of the proceedings in the most lively and kindly manner. It was while we were passing from one part of the factory to another that I observed the beautiful steam-engine which gave motion to the tools and machinery of the workshops. The man who attended it was engaged in cleaning out the ashes from under the boiler furnace, 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 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.

It consisted in the employment of a knife-edged hardened steel instrument, so arranged as to be set at any required angle, and its edge caused to penetrate the surface of a cylindrical bar of soft steel or brass. This bar being revolved under the incisive action of the angularly placed knife-edged instrument, it thus received a continuous spiral groove cut into its surface. It was then in the condition of a rudimentary screw; the pitch, or interval between the threads, being determined by the greater or less angle of obliquity at which the knife-edged instrument was set with respect to the axis of the cylindrical bars revolving under its incisive action.

The spiral groove, thus generated, was deepened to the required extent by a suitable and pointed hard steel tool firmly held in the jaws of an adjustable slide made for the purpose, as part and parcel of the bed of the machine. In the case of square-threaded screws being required, a square-pointed tool was employed in place of the V or angle-threaded tool. And in order to generate or produce right hand or left hand screws, all that was necessary was to set the knife-edged instrument to a right or left hand inclination in respect to the axis of the cylindrical bar at the outset of the operation.

This beautiful and truly original contrivance became, in the hands of its inventor, the parent of a vast progeny of perfect screws, whose descendants, whether legitimate or not, are to be found in every workshop throughout the world, wherever first-class machinery is constructed. The production of perfect screws was one of Maudslay's highest ambitions and his principal technical achievement. It was a type of his invaluable faculty of solving the most difficult problems by the most direct and simple methods.

It was by the same method that he produced the Guide screw. His screw-cutting lathe was moved by combination wheels, and by its means he could, by the one Guide screw, obtain screws of every variety of pitch and diameter. As an illustration of its complete accuracy I may mention that by its means a screw of five feet in length and two inches in diameter was cut with fifty threads to the inch; the Nut to fit on to it being twelve inches long, and containing six hundred threads! This screw was principally used for dividing scales for astronomical and other metrical purposes of the highest class. By its means divisions were produced with such minuteness that they could only be made visual by a microscope.

This screw was sent for exhibition to the Society of Arts. It is still preserved with the utmost care at the Lambeth Works amongst the many admirable specimens of Henry Maudslay's inventive genius and delicate handiwork. Every skilled mechanic must thoroughly enjoy the sight of it, especially when he knows that it was not produced by an exceptional tool, but by the machine that was daily employed in the ordinary work of the factory.

I must not, however, omit to say that I took an early opportunity of presenting Brougham's letter of introduction to Faraday at the Royal Institution. I was received most cordially by that noble-minded man, whose face beamed with goodness and kindness. After some pleasant conversation he said he would call upon me at Maudslay's, whom he knew very well. Not long after Faraday called, and found me working beside Maudslay in his beautiful little workshop. A vice had been fitted up for me at the bench where he himself daily worked. Faraday expressed himself as delighted to find me in so enviable a position. He congratulated me on my special good fortune in having the inestimable advantage of being associated as assistant workman with one of the greatest mechanical engineers of the day.

Mr. Maudslay offered to conduct Faraday through his workshops, and I was permitted to accompany them. I was much impressed with the intelligent conversation of Faraday, as well as with the quickness he exhibited in appreciating not only the general excellence of the design and execution of the works in progress, but his capacity for entering into the technical details of the composite tools and machinery which he saw during his progress through the place. This most pleasant and memorable meeting with the great philosopher initiated a friendship which I had the good fortune to continue until the close of his life.

It was, of course, an immense advantage for me to be so intimately associated with Mr. Maudslay in carrying on his experimental work. I was not, however, his apprentice, but his assistant workman. It was necessary, therefore, in his opinion, that I should receive some remuneration for my services. Accordingly, at the conclusion of my first week in his service, he desired me to go to his chief cashier and arrange with him for receiving whatever amount of weekly wages I might consider satisfactory. I went to the counting-house and had an interview with Mr. Young the cashier, a most worthy man* [footnote... I may mention that he was brother to Dr. Thomas Young, the celebrated natural philosopher. ...] Knowing as I did the great advantages of my situation, and having a very modest notion of my own worthiness to occupy it, I said, in answer to Mr. Young's question as to the amount of wages I desired, that "if he did not think ten shillings a week too much I could do well enough with that." "Very well" said he,"let it be so" And he handed me over half a sovereign!

I had determined, after I obtained a situation, not to cost my father another shilling. I knew how many calls he had upon him, at a time when he had his own numerous household to maintain. I therefore resolved, now that I had begun life on my own resources, to maintain myself, and to help him rather than be helped any longer. Thus the first half-sovereign I received from Mr. Young was a great event in my life. It was the first wages, as such, that I had ever received. I well remember the high satisfaction I felt as I carried it home to my lodgings; and all the more so as I was quite certain that I could, by strict economy and good management, contrive to make this weekly sum of ten shillings meet all my current expenses.

I had already saved the sum of #20, which I placed in the bank as a deposit account. It was the residue of the sale of some of my model steam-engines at Edinburgh. My readers will remember that I brought with me a model steam-engine to show to Mr. Maudslay as a specimen of my handiwork. It had gained for me the situation that I desired, and I was now willing to dispose of it. I found a purchaser in Mr. Watkins, optician at Charing Cross, who supplied such apparatus to lecturers at Mechanics' Institutions. He gave me #35 for the model, and I added the sum to my deposit account. This little fund was quite sufficient to meet any expenses beyond those of a current weekly nature.

[Image] My cooking stove* [footnote... I have this handy apparatus by me still; and to prove its possession of its full original efficiency I recently set it in action after its rest of fifty years, and found that it yielded results quite equal to my grateful remembrance of its past services. ...]

But I was resolved that my wages alone should maintain me in food and lodging. I therefore directed my attention to economical living. I found that a moderate dinner at an eating-house would cost move than I could afford to spend. In order to keep within my weekly income I bought the raw materials and cooked them in my own way and to my own taste. I set to and made a drawing of a very simple, compact, and handy cooking apparatus. I took the drawing to a tinsmith near at hand, and in two days I had it in full operation. The apparatus cost ten shillings, including the lamp. As it contributed in no small degree to enable me to carry out my resolution, and as it may serve as a lesson to others who have an earnest desire to live economically, I think it may be useful to give a drawing and a description of my cooking stove. The cooking or meat pan rested on the upper rim of the external cylindrical case, and was easily removable in order to be placed handy for service. The requisite heat was supplied by an oil lamp with three small single wicks, though I found that one wick was enough. I put the meat in the pot, with the other comestibles, at nine o'clock in the morning. It simmered away all day, until half-past six in the evening, when I came home with a healthy appetite to enjoy my dinner. I well remember the first day that I set the apparatus to work. I ran to my lodging, at about four P.M., to see how it was going on. When I lifted the cover it was simmering beautifully, and such a savoury gusto came forth that I was almost tempted to fall to and discuss the contents. But the time had not yet come, and I ran back to my work.

The meat I generally cooked in it was leg of beef, with sliced potato, bits of onion chopped down, and a modicum of white pepper and salt, With just enough of water to cover "the elements." When stewed slowly the meat became very tender; and the whole yielded a capital dish, such as a very Soyer might envy. It was partaken of with a zest that, no doubt, was a very important element in its savouriness. The whole cost of this capital dinner was about 4 1/2d. I sometimes varied the meat with rice boiled with a few raisins and a pennyworth of milk. My breakfast and tea, with bread, cost me about fourpence each. My lodgings cost 3s. 6d. a week. A little multiplication will satisfy any one how it was that I contrived to live economically and comfortably on my ten shillings a week. In the following year my wages were raised to fifteen shillings a week, and then I began to take butter to my bread.

To return to my employment under Mr. Maudslay. One of the first jobs that I undertook was in assisting him to make a beautiful small model of a pair of 200 horsepower marine steam-engines. The engines were then in course of construction in the factory. They were considered a bold advance on the marine engines then in use, not only in regard to their great power, but in carrying out many specialities in their details and general structure. Mr. Maudslay had embodied so much of his thought in the design that he desired to have an exact model of them placed in his library, so as to keep a visible record of his ideas constantly before him. In fact, these engines might be regarded as the culmination of his constructive abilities.

In preparing the model it was necessary that everything should be made in exact conformity with the original. There were about three hundred minute bolts and nuts to be reduced to the proportional size. I esteemed it a great compliment to be entrusted with their execution. They were all to be made of cast-steel, and the nuts had to be cut to exact hexagonal form. Many of them had collars. To produce them by the use of the file in the ordinary mode would not only have been difficult and tedious, but in some cases practically impossible.

To get rid of the difficulty I suggested to Mr. Maudslay a contrivance of my own by means of which the most rigid exactness in size as well as form could be given to these hexagonal nuts. He readily granted his permission. I constructed a special apparatus, consisting of a hard steel circular cutter to act as a circular file. When brought into operation in the production of these minute six-sided collared nuts, held firm in the spindle of a small dividing plate and attached to the slide-rest, each side was brought in succession under the action of the circular file or cutter with the most exact precision in regard to the division of the six sides. The result was absolutely perfect as respects the exactness of the six equal sides of the hexagonal nut, as well as their precise position in regard to the collar that was of one solid piece with it. There was no great amount of ingenuity required in contriving this special tool, or in adapting it to the slide-rest of the lathe, to whose spindle end the file or cutter / was fixed. But the result was so satisfactory, both as regards the accuracy and rapidity of execution in comparison with the usual process of hand filing, that Mr. Maudslay was greatly pleased with the arrangement as well as with my zeal in contriving and executing this clever little tool. An enlarged edition of this collar-nut cutting machine was soon after introduced into the factory.

[Image] Arrangement of the machine

It was one of the specialities that I adopted in my own workshop when I commenced business for myself, and it was eagerly adopted by mechanical engineers, whom we abundantly supplied with this special machine. It was an inestimable advantage to me to be so intimately associated with this Great Mechanic. He was so invariably kind, pleasant, and congenial. He communicated an infinite number of what he humorously called "Wrinkles" which afterwards proved of great use to me. My working hours usually terminated at six in the evening. But as many of the departments of the factory were often in full operation during busy times until eight o'clock, I went through them to observe the work while in progress. On these occasions I often met "the guvnor, as the workmen called Mr. Maudslay. He was going his round of inspection, and when there was any special work in hand he would call me up to him to and explain point in connection with it that was worthy of particular notice. I found this valuable privilege most instructive, as I obtained from the cheif mechanic himself a full insight into the methods, means, and processes by which the skilful workman advanced the various classes of work. I was also permitted to take notes and make rapid sketches of any object that specially interested me. The entire establishment thus became to me a school of practical engineering of the most instructive kind.

Mr. Maudslay took pleasure in showing me the right system and method of treating all manner of materials employed in mechanical structures. He showed how they might be made to obey your will, by changing them into the desired forms with the least expenditure of time and labour. This in fact is the true philosophy of construction. When clear ideas have been acquired upon the subject, after careful observation and practice, the comparative ease and certainty with which complete mastery over the most obdurate materials is obtained, opens up the most direct road to the attainment of commercial as well as of professional success.

To be permitted to stand by and observe the systematic way in which Mr. Maudslay would first mark or line out his work, and the masterly manner in which he would deal with his materials, and cause them to assume the desired forms, was a treat beyond all expression. Every stroke of the hammer, chisel, or file, told as an effective step towards the intended result. It was a never-to-be-forgotten practical lesson in workmanship, in the most exalted sense of the term. In conformity with his often repeated maxim, "that there is a right way and a wrong way of doing everything," he took the shortest and most direct cuts to accomplish his objects. He illustrated this by telling me, in his own humorous style, " When you want to go from London to Greenwich, don't go round by Inverness." Another of his droll sayings was that he "considered no man a thorough mechanic unless he could cut a plank with a gimlet, and bore a hole with a saw!"

The grand result of thoughtful practice is what we call experience: it is the power or faculty of seeing clearly before you begin, what to avoid and what to select—or rather what to do and what not to do. High-class workmanship, or technical knowledge, was in his hands quite a science. Every piece of work was made subject to the soundest philosophical principles, as applied to the use and treatment of materials. It was this that gave such a charm of enjoyment to his dealing with tools and materials. He loved this sort of work for its own sake, far more than for its pecuniary results. At the same time he was not without regard for the substantial evidence of his supremacy in all that regarded first-class tools, admirable management, and thorough organisation of his factory.

The innate love of truth and accuracy which distinguished Mr. Maudslay, led him to value highly that class of technical dexterity in engineering workmen which enabled them to produce those details of mechanical structures in which perfect flat or true plane surfaces were required. This was an essential condition for the effective and durable performance of their functions. Sometimes this was effected by the aid of the turning-lathe and slide-rest. But in most cases the object was attained by the dexterous use of the file, so that "flat filing" then was, as it still is, one of the highest qualities of the skilled workman. No one that I ever met with could go beyond Henry Maudslay himself in his dexterous use of the file. By a few masterly strokes he could produce plane surfaces so true that when their accuracy was tested by a standard plane surface of absolute truth, they were never found defective; neither convex, nor concave, nor "cross-winding,"—that is, twisted.
