The greatest masters of dramatic construction that have made their appearance in the present century are probably Bulwer Lytton and Dion Boucicault; and each has left good examples of treatment in both schools. Bulwer, in the "Lady of Lyons" and "Richelieu," both romantic plays, with the regular villanous element, has used the front scene to advantage wherever he found it necessary. In "Money," on the other hand, a scientific comedy of the very first order, the five pictures succeed each other with no disturbance but that of the curtain. The plot of "Money," be it observed, is quite simple, the characters few, the intention that of the old Greek comedy--a satire on manners. Boucicault, in his latest success--the "Shaughraun"--and in his other Irish dramas, notably the "Colleen Bawn," uses three and even five scenes in an act, with perfect freedom, while in others, almost as successful in their day, such as "Jessie Brown," "Octoroon," the French form seemed to him to be preferable. Some principle must have guided him in this distinction, as it did Bulwer, and the same elements probably decided both to tell one story in one way, the other in another. It is observable that both treat a romantic and complicated story, with numerous characters and considerable of the villanous element, in numerous scenes, whereas a realistic picture of actual manners, such as "Money," "Octoroon," "Jessie Brown," falls naturally into few scenes. The climax of each of these last mentioned plays, be it observed, is produced by the operation of general causes, the laws of society in "Money" and "Octoroon," the operation of a historical fact in "Jessie Brown," while in the romantic plays the climax depends on the action of the characters, determined by accidental circumstances, irrespective of general laws. The respective rank of "Money" and the "Lady of Lyons" in the lapse of years can hardly, I think, be doubted. The first will hold its own with the "School for Scandal," when the "Lady of Lyons" is forgotten, along with "The Duenna." The recent success of Augustin Daly in adapting the "School for Scandal" to mono-scenic acts shows how readily that form lends itself to the exigencies of legitimate comedy. The single fault of that adaptation is that the first act drags, just as Sardou's first acts always drag, but the audience forgets that as the story progresses. The result of our ramble through the instances mentioned seems to be this canon: XIV. Mono-scenic acts are best for high comedy, realistic and society dramas; multi-scenic acts succeed best with romantic and complicated plots.
