The Works of Robert Louis Stevenson – Swanston Edition. Volume 9. Robert Louis Stevenson
I might hear the song of the wonderful birds,
Source of happiness;
That I might hear the thunder of the crowding waves
Upon the rocks:
At times at work without compulsion —
This would be delightful;
At times plucking dulse from the rocks;
At times at fishing.”
So, about the next island of Iona, sang Columba himself twelve hundred years before. And so might I have sung of Earraid.
And all the while I was aware that this life of sea-bathing and sun-burning was for me but a holiday. In that year cannon were roaring for days together on French battle-fields; and I would sit in my isle (I call it mine, after the use of lovers) and think upon the war, and the loudness of these far-away battles, and the pain of the men’s wounds, and the weariness of their marching. And I would think too of that other war which is as old as mankind, and is indeed the life of man; the unsparing war, the grinding slavery of competition; the toil of seventy years, dear-bought bread, precarious honour, the perils and pitfalls, and the poor rewards. It was a long look forward; the future summoned me as with trumpet calls, it warned me back as with a voice of weeping and beseeching; and I thrilled and trembled on the brink of life, like a childish bather on the beach.
There was another young man on Earraid in these days, and we were much together, bathing, clambering on the boulders, trying to sail a boat and spinning round instead in the oily whirlpools of the roost. But the most part of the time we spoke of the great uncharted desert of our futures; wondering together what should there befall us; hearing with surprise the sound of our own voices in the empty vestibule of youth. As far, and as hard, as it seemed then to look forward to the grave, so far it seems now to look backward upon these emotions; so hard to recall justly that loath submission, as of the sacrificial bull, with which we stooped our necks under the yoke of destiny. I met my old companion but the other day; I cannot tell of course what he was thinking; but, upon my part, I was wondering to see us both so much at home, and so composed and sedentary in the world; and how much we had gained, and how much we had lost, to attain to that composure; and which had been upon the whole our best estate: when we sat there prating sensibly like men of some experience, or when we shared our timorous and hopeful counsels in a western islet.
IX
THOMAS STEVENSON
The death of Thomas Stevenson will mean not very much to the general reader. His service to mankind took on forms of which the public knows little and understands less. He came seldom to London, and then only as a task, remaining always a stranger and a convinced provincial; putting up for years at the same hotel where his father had gone before him; faithful for long to the same restaurant, the same church, and the same theatre, chosen simply for propinquity; steadfastly refusing to dine out. He had a circle of his own, indeed, at home; few men were more beloved in Edinburgh, where he breathed an air that pleased him; and wherever he went, in railway carriages or hotel smoking-rooms, his strange, humorous vein of talk, and his transparent honesty, raised him up friends and admirers. But to the general public and the world of London, except about the parliamentary committee-rooms, he remained unknown. All the time, his lights were in every part of the world, guiding the mariner; his firm were consulting engineers to the Indian, the New Zealand, and the Japanese Lighthouse Boards, so that Edinburgh was a world-centre for that branch of applied science; in Germany, he had been called “the Nestor of lighthouse illumination”; even in France, where his claims were long denied, he was at last, on the occasion of the late Exposition, recognised and medalled. And to show by one instance the inverted nature of his reputation, comparatively small at home, yet filling the world, a friend of mine was this winter on a visit to the Spanish main, and was asked by a Peruvian if he “knew Mr. Stevenson the author, because his works were much esteemed in Peru.” My friend supposed the reference was to the writer of tales; but the Peruvian had never heard of “Dr. Jekyll”; what he had in his eye, what was esteemed in Peru, were the volumes of the engineer.
Thomas Stevenson was born at Edinburgh in the year 1818; the grandson of Thomas Smith, first engineer to the Board of Northern Lights, son of Robert Stevenson, brother of Alan and David; so that his nephew, David Alan Stevenson, joined with him at the time of his death in the engineership, is the sixth of the family who has held, successively or conjointly, that office. The Bell Rock, his father’s great triumph, was finished before he was born; but he served under his brother Alan in the building of Skerryvore, the noblest of all extant deep-sea lights; and, in conjunction with his brother David, he added two – the Chickens and Dhu Heartach – to that small number of man’s extreme outposts in the ocean. Of shore lights, the two brothers last named erected no fewer than twenty-seven; of beacons,6 about twenty-five. Many harbours were successfully carried out: one, the harbour of Wick, the chief disaster of my father’s life, was a failure; the sea proved too strong for man’s arts; and after expedients hitherto unthought of, and on a scale hyper-cyclopean, the work must be deserted, and now stands a ruin in that bleak, God-forsaken bay, ten miles from John-o’-Groat’s. In the improvement of rivers the brothers were likewise in a large way of practice over both England and Scotland, nor had any British engineer anything approaching their experience.
It was about this nucleus of his professional labours that all my father’s scientific inquiries and inventions centred; these proceeded from, and acted back upon, his daily business. Thus it was as a harbour engineer that he became interested in the propagation and reduction of waves; a difficult subject, in regard to which he has left behind him much suggestive matter and some valuable approximate results. Storms were his sworn adversaries, and it was through the study of storms that he approached that of meteorology at large. Many who knew him not otherwise, knew – perhaps have in their gardens – his louvre-boarded screen for instruments. But the great achievement of his life was, of course, in optics as applied to lighthouse illumination. Fresnel had done much; Fresnel had settled the fixed light apparatus on a principle that still seems unimprovable; and when Thomas Stevenson stepped in and brought to a comparable perfection the revolving light, a not unnatural jealousy and much painful controversy rose in France. It had its hour; and, as I have told already, even in France it has blown by. Had it not, it would have mattered the less, since all through his life my father continued to justify his claim by fresh advances. New apparatus for lights in new situations was continually being designed with the same unwearied search after perfection, the same nice ingenuity of means; and though the holophotal revolving light perhaps still remains his most elegant contrivance, it is difficult to give it the palm over the much later condensing system, with its thousand possible modifications. The number and the value of these improvements entitle their author to the name of one of mankind’s benefactors. In all parts of the world a safer landfall awaits the mariner. Two things must be said: and, first, that Thomas Stevenson was no mathematician. Natural shrewdness, a sentiment of optical laws, and a great intensity of consideration, led him to just conclusions; but to calculate the necessary formulæ for the instruments he had conceived was often beyond him, and he must fall back on the help of others, notably on that of his cousin and lifelong intimate friend, emeritus Professor Swan,7 of St. Andrews, and his later friend, Professor P. G. Tait. It is a curious enough circumstance, and a great encouragement to others, that a man so ill equipped should have succeeded in one of the most abstract and arduous walks of applied science. The second remark is one that applies to the whole family, and only particularly to Thomas Stevenson from the great number and importance of his inventions: holding as the Stevensons did a Government appointment, they regarded their original work as something due already to the nation, and none of them has ever taken out a patent. It is another cause of the comparative obscurity of the name; for a patent not only brings in money, it infallibly spreads reputation; and my father’s instruments enter anonymously into a hundred light-rooms, and are passed anonymously over in a hundred reports, where the least considerable patent would stand out and tell its author’s story.
But the life-work of Thomas Stevenson remains; what we have lost, what we now rather try to recall, is the friend and companion. He was a man of a somewhat antique strain: with a blended sternness and
