St. Pierre was already thirty-one years old when he took his distant voyage; he stayed three years in Mauritius, and then he waited sixteen years, becoming therefore, fifty years old, before he made use of what he had experienced in publishing his romance of "Paul and Virginia." He had meantime seen a great deal of Rousseau during the latter's declining years, and from him had learned that art of writing by virtue of which he was destined to constitute the second of succession in a literary line to be continued after him in Chateaubriand and Lamartine, in Madame de Stael and George Sand. It is the historical importance thus attaching to St. Pierre's name, even more perhaps than it is the merit and the fame of his books, or of his book--for of his books other than "Paul and Virginia," we need not trouble our readers with even the titles--that warrants us in listing him, as we do, among the select "immortals" of French literature. St. Pierre's distinguishing note was the supposed return to nature and to natural unsophisticated sentiment accomplished in his writings. But the return, with him, was by no means completely satisfactory. There was always something unreal in St. Pierre's passion for nature; and the feeling with which he wrote seems, to us of to-day, to have been neither very deep nor very sincere. Still, all was accepted and was highly effective in its time; Europe was flooded with tears in reading "Paul and Virginia," much as afterward it was flooded with tears in reading an equally notable, but far less wholesome book, that prose masterpiece of the youthful Goethe, "The Sorrows of Werther." The "Corinne" of Madame de Stael afterward, later the "Jocelyn" of Lamartine, later again the passionate earlier novels of George Sand, served to their respective fresh generations of readers a somewhat similar office, that of stimulating and of expressing the vague longing and aspiration of youth. The plot of "Paul and Virginia" is simplicity itself. Two young French widows--widows we may euphemistically call the women both, though the mother of Paul had never been married--meet, strangers to each other, in Mauritius, and their children, Paul and Virginia respectively, grow up from babyhood together, as if brother and sister, in a state of nature such as never was anywhere in the world outside of a romance, until at last, Virginia undertaking a vain voyage to France to bring round a rich alienated aunt of her mother's, perishes by shipwreck on her return; in prompt sequel of which calamity, all the remaining personages of the tale, down to the very dog, naturally and sentimentally, one after another, die. The story is represented as told to a traveler in the Isle of France by a sympathetic old man who had been an eye-witness of all. Two extracts, one from the beginning, and one from the end, of the romance, will sufficiently indicate its quality.
