dictionaries of antiquities or volumes of travel must damage the illusion which is the indispensable element of romance. In Moore's fantastic metrical romance of _Lalla Rookh_ the system was carried to an extent that now seems ridiculous, for certain passages are loaded with outlandish phrases or metaphors that are unintelligible except by reference to the notes. Nevertheless the English public, being then quite ignorant of the true East, tolerated Moore's sham Orientalism, even though Byron's fine poems were just then exposing the difference between working up the subject in a library and wandering in Asiatic countries. Byron's language seems in the present day turgid, and his Greeks and Turks may have a theatrical air, but his splendid descriptive passages were drawn by a master hand straight from nature, while his colouring, landscape, and costume are usually excellent; so that his work also is a distinct movement in the direction of realism. Yet it is to be observed that after Byron and Scott the metrical romance, that most ancient form of tale-telling, fell rapidly into disuse. The fact that Byron's latest poem, _Don Juan_, belonged essentially to the coming realistic school, is a significant indication of transition; and Scott's abandonment of poetry for prose, which was a necessary consequence of his advance toward realism, gave its death-blow to the earlier fashion. By this time, indeed, the conventional writer of adventures, though he held his ground up to or even beyond the middle of the century, was in a state of incurable decadence. He was losing the confidence of the general reader, who had picked up some precise notions regarding appropriate scenery, language, and costume in sundry periods and divers places, from China to Peru; and he was persecuted by that mortal foe of the old romancer, the well-informed critic, who trampled even upon a commonplace book well filled with references to standard authorities, insisting upon careful study of the whole environment, the dexterous incorporation of details, and delicate blending of local colours. Severe pedagogic handling of a historic novel, as if it were a paper done at some competitive examination, was too much for the old school, which finally subsided into cheap popular editions, making way for a new class of writers that adapted the Novel of Adventure to the requirements of latter-day taste, to the widening of knowledge, and the diversified expansion of our national life. The prevailing tendency was now to confine the range of scene and action more and more approximately to the contemporary period, to insist on genuine materials, and to observe a stricter canon of probabilities, wherein the discriminating reader fancied himself to be a judge. The use of notes was discarded as contrary to the high artistic principle that in fiction everything must resemble reality while nothing must be demonstrably matter of fact. The appearance of famous personages must
