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 s.h.i.+ps 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 princ.i.p.al 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 cla.s.ses.
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 princ.i.p.al part of my own education. It gave me the power of recording observations with a few graphic strokes of the pencil, which far surpa.s.sed 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 gla.s.s tubes and blow bulbs for thermometers, to a.n.a.lyse metals or mineral substances, or to do any other work for which intense heat was necessary.
My natural apt.i.tude 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 friends.h.i.+p 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 cla.s.s 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 Ba.s.s 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-gla.s.s,”
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 mult.i.tude, 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 pa.s.sed off loyally, orderly, happily, and successfully.
Shortly after this time there was a great deal of distress among the labouring cla.s.ses. 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 cras.h.i.+ng 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 gla.s.s. 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 ma.s.ses 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 guards.h.i.+p 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, pa.s.sing, on our way up the Firth, Queensferry, Culross, and Alloa.
