The "producer" of the play, the person who assumes the responsibility for the performance in all its details, may be the dramatist himself; M. Sardou and Mr. Belasco have shown surpassing skill in bringing forth all that lies latent in the inert manuscripts of their plays. He may be the actual manager of the theater; the late Augustin Daly was a stage-manager of striking individuality. He may be the actor of the chief part in the play; Mr. Willard and Mr. Sothern have revealed another aspect of their talent by the artistic manner in which they have staged both new plays and old. He may be at once author and actor and manager, like Mr. Gillette, a past-master of this new and difficult art. Or he may be simply a stage-manager and nothing else, a craftsman of a new calling, not author, not actor, yet able on occasion to give hints to playwright and to player. Here, again, is another resemblance to the conductor, who can impose his own will on the orchestra, altho he may not be able to play one of the instruments in it, and altho he may be quite incapable of composing. That the task of the stage-manager is more difficult than that of the conductor is due to the fact that the composer has prescribed exactly what share each instrument shall take, the conductor having this full score in his possession; whereas the stage-manager receives from the author only the spoken words of the play, with but summary indications as to the gestures, the movements, the scenery, and so forth. He has not a full score, but only a sequence of themes incompletely orchestrated, and with the missing passages to be supplied at his own discretion. And as the richness of the harmony depends largely upon his ability to amplify properly the hints of the author, the stage-manager is, in fact, almost a collaborator of the playwright; he is forced into a more intimate relation with the dramatist than that which the conductor bears toward the composer. To a collaboration of this sort, ordinary playgoers never give a thought, content to take the performance as they see it, and ready often to credit the actor, not only with the inventions of the stage-manager, but even with those of the author also. They accept the play as it is presented to them, just as tho it had happened, with no suspicion of the forethought by which the performance has been made possible.
