"Rob Roy" was published in the latter part of 1817, and was received by the public with the same unabated enthusiasm which marked the appearance of "Guy Mannering" and the other romances. An edition of ten thousand was disposed of in two weeks, and the subsequent sale amounted to forty thousand more. The scene of this story is laid in the Highlands of Scotland, with an English hero and a Scottish heroine; and in this fascinating work the political history of the times (forty years earlier than the period of "Waverley") is portrayed with great impartiality. It is a description of the first Jacobite rising against George I. in the year 1715. In this novel one of the greatest of Scott's creations appears in the heroine, Diana Vernon,--rather wild and masculine, but interesting from her courage and virtue. The character of Baillie Jarvie is equally original and more amusing. The general effect of "Rob Roy," as well as of "Waverley" and "Old Mortality," was to make the Scottish Highlanders and Jacobites interesting to English readers of opposite views and feelings, without arousing hostility to the reigning royal family. The Highlanders a hundred years ago were viewed by the English with sentiments nearly similar to those with which the Puritan settlers of New England looked upon the Indians,--at any rate, as freebooters, robbers, and murderers, who were dangerous to civilization; and the severities of the English government toward these lawless clans, both as outlaws and as foes of the Hanoverian succession, were generally condoned by public opinion. Scott succeeded in producing a better feeling among both the conquerors and the conquered. He modified general sentiment by his impartial and liberal views, and allayed prejudices. The Highlanders thenceforth were regarded as a body of men with many interesting traits, and capable of becoming good subjects of the Crown; while their own hatred and contempt of the Lowland Saxon were softened by the many generous and romantic incidents of these tales. Two hitherto hostile races were drawn into neighborly sympathy. Travellers visited the beautiful Highland retreats, and returned with enthusiastic impressions of the country. To no other man does Scotland owe so great a debt of gratitude as to Walter Scott, not only for his poetry and novels, but for showing the admirable traits of a barren country and a fierce population, and contributing to bring them within the realm of civilization. A century or two ago the Highlands of Scotland were peopled by a race in a state of perpetual conflict with civilization, averse to labor, gaining (except such of them as were enrolled in the English Army) a precarious support by plunder, black-mailing, smuggling, and other illegal pursuits. Now they compose a body of hard-working, intelligent, and law-abiding laborers, cultivating farms, raising cattle and sheep, and pursuing the various branches of industry which lead to independence, if not to wealth.
