The year 1878 was to Stevenson one of great productiveness. In May was issued his first book, ‘The Inland Voyage,’ containing the account of his canoe trip, and written in a pleasant fanciful vein of humour -nd reflection, but with the style a little over-mannered. Besides six or eight characteristic essays of the ‘Virginibus Puerisque’ series, there appeared in ‘London’ (edited by Mr. Henley) the set of fantastic modern tales called the ‘New Arabian Nights,’ conceived in a very spirited and entertaining vein of the realistic-unreal, as well as the story of ‘Providence and the Guitar;’ and in the ‘Portfolio’ the ‘Picturesque Notes on Edinburgh,’ republished at the end of the year in book form. During the autumn and winter of this year he wrote ‘Travels with a Donkey in the Cevennes,’ and was much engaged in the planning of plays in collaboration with Mr. Henley, of which one, ‘Deacon Brodie,’ was finished in the spring of 1879. This was also the date of the essay ‘On some Aspects of Burns.’ In the same spring he drafted in Edinburgh, but afterwards laid by, four chapters on ethics (a study to which he once referred as being always his ‘veiled mistress’) under the name of ‘Lay Morals.’ In few men have the faculties been so active on the artistic and the ethical sides at once, and this fragment is of especial interest in the study of its author's mind and character.
By his various published writings Stevenson had made little impression as yet on the general reader. But the critical had recognised in him a new artist of the first promise in English letters, who aimed at, and often achieved, those qualities of sustained precision, lucidity, and grace of style which are characteristic of the best French prose, but in English rare in the extreme. He had known how to stamp all he wrote with the impress of a vivid personal charm; had shown himself a master of the apt and animated phrase; and whether in tale or parable, essay or wayside musing, had touched on vital points of experience and feeling with the observation and insight of a true poet and humourist.
The year 1879 was a critical one in Stevenson's life. In France he had met an American lady, Mrs. Osbourne (née Van de Grift), whose domestic circumstances were not fortunate, and who was living with her daughter and young son in the art-student circles of Paris and Fontainebleau. At the beginning of 1879 she returned to California. In June Stevenson determined to follow. He travelled by emigrant ship and train, partly for economy, partly for the sake of the experience. The journey and its discomforts proved disastrous to his health, but did not interrupt his industry. Left entirely to his own resources, he stayed for eight months partly at Monterey and partly at San Francisco. During a part of these months he was at death's door from a complication of pleurisy, malarial fever, and exhaustion of the system, but managed nevertheless to write the story of ‘The Pavilion on the Links,’ two or three essays for the ‘Cornhill Magazine,’ the greater part of a Californian story, ‘A Vendetta in the West’ (never published), a first draft of the romance of ‘Prince Otto,’ and the two parts of the ‘Amateur Emigrant’ (not published till some years later). He also tried to get work on the local press, and some contributions were printed in the ‘Monterey Independent;’ but on the whole his style was not thought up to Californian standards. In the spring of 1880 he was married to Mrs. Osbourne, who had obtained some months before a divorce from her husband. She nursed him through the worst of his illness, and in May they went for the sake of health to lodge at a deserted mining station above Calistoga, in the Californian coast range. The story of this sojourn is told in the ‘Silverado Squatters.’
Later, Stevenson brought his wife home in August 1880. She was to him a perfect companion, taking part keenly and critically in his work, sharing all his gipsy tastes and love of primitive and natural modes of life, and being, in spite of her own precarious health, the most devoted and efficient of nurses in the anxious times which now ensued.
For the next seven or eight years Stevenson's life seemed to hang by a thread. Chronic lung disease had declared itself, and the slightest exposure or exertion was apt to bring on a prostrating attack of cough, hæmorrhage, and fever. The trial was manfully borne; and in every interval of respite he worked in unremitting pursuit of the standards he had set before himself.
Between 1880 and 1887 he lived the life of an invalid, vainly seeking relief by change of place. After spending six weeks (August and September 1880) with his parents at Blair Athol and Strathpeffer, he went in October, with his wife and stepson, to winter at Davos, where he made fast friends with John Addington Symonds (1840–1893) [q. v.] and his family. He wrote little, but prepared for press the collected essays ‘Virginibus Puerisque,’ in which he preaches with captivating vigour and grace his gospel of youth, courage, and a contempt for the timidities and petty respectabilities of life. For the rest, he amused himself with verses playful and other, and with supplying humorous text and cuts (‘Moral Emblems,’ ‘Not I,’ &c.) for a little private press worked by his young stepson. Returning to Scotland at the end of May with health somewhat improved, he spent four months with his parents at Pitlochry and Braemar. At Pitlochry he wrote ‘Thrawn Janet’ and the chief part of ‘The Merry Men,’ two of the strongest short tales in Scottish literature, the one of Satanic possession, the other of a conscience and imagination haunted, to the overthrow of reason, by the terrors of the sea. At Braemar he began ‘Treasure Island,’ his father helping with suggestions and reminiscences from his own seafaring experiences. At the suggestion of Mr. A. H. Japp, the story was offered to, and accepted by, the editor (Mr. Henderson) of a boys' periodical called ‘Young Folks.’ In the meantime (August 1881) Stevenson had been a candidate for the vacant chair of history and constitutional law at Edinburgh. In the light of such public reputation as he yet possessed, the candidature must have seemed paradoxical; but it was encouraged by competent advisers, including the retiring professor, Dr. Æneas Mackay. It failed. Had it succeeded, his health would almost certainly have proved unequal to the work. A cold and wet season at Braemar did him much harm; and in October he was ordered off to spend a second winter (1881–2) at Davos. He here finished the tale of ‘Treasure Island,’ began, on the suggestion of Mr. George Bentley, a life (never completed) of William Hazlitt, and prepared for press the collection of literary essays ‘Familiar Studies of Men and Books.’
In the summer of 1882 he again tried Scotland (Stobo Manse in Upper Tweedale, Lochearnhead, and Kingussie), and again with bad results for his health. As his wife was never well at Davos, they determined to winter in the south, and settled before Christmas in a cottage near Marseilles (Campagne Defli, St. Marcel). Thence being presently driven by a fever epidemic, they moved in January 1883 to a châlet in a pleasant garden on a hill behind Hyères (Châlet la Solitude). Here Stevenson enjoyed a respite of nearly a year from acute illness, as well as the first breath of popular success on the publication in book form of ‘Treasure Island.’ In this story the force of invention and vividness of narrative appealed to every reader, including those on whom its other qualities of style and character-drawing would in themselves have been thrown away; and it has taken its place in literature as a classic story of pirate and mutineer adventure. It has been translated into French, Spanish, and other languages. Partly at Marseilles and partly at Hyères he wrote the ‘Treasure of Franchard,’ a pleasant and ingenious tale of French
