IT was in 1880 and 1881 that Stevenson wrote Treasure Island, which was begun at Braemar, Scotland, where his father aided him with suggestions from his own seafaring experiences. It was finished in the course of his second visit to Davos in the winter of 1881-82. In 1878 he had published his first book, The Island Voyage, which was followed by Travels with a Donkey. He had also written the tales known as "The New Arabian Nights," the essays collected under the title of Virginibus Puerisque, and other stories and essays, but Treasure Island, which appeared when the author was thirty-one, was his first long romance, and it brought to him his first taste of popular success, when the story was published in book form. It was in October, 1881, that this story began to appear as a serial in an English magazine called Young Folks. The title then was "The Sea Cook, or Treasure Island," but when published in book form in May, 1883, the name was simply Treasure Island, a name which has taken its place among the titles of far older classics. I remember well that as a boy in England I was obliged to satisfy my craving for sea-stories with books like Captain Cook's Voyages and The Mutiny of the "Bounty." The latter dreadful tale must have been read by Stevenson and perhaps afforded some suggestions. It has seemed to me that before Treasure Island there was no really great sea-tale for younger readers. The immortal Swiss Family Robinson and Robinson Crusoe belonged to a different category, and Dana's Two Years before the Mast was little known to English youth. It seems to me fair to say that Treasure Island is the only great modern classic written especially for younger readers.
