Of course, the drama can utilize enthusiasm and imagination quite as often and quite as abundantly as can prose fiction, but it must use these precious gifts with a discretion which is not imposed upon its rival. In a novel enthusiastic imagination may lure the story-teller into a host of by-paths not foreseen by him when he set out on his journey; and while he is adventuring himself in these by-paths, he may chance to encounter characters of a diverting or an appealing personality, whom it may amuse him to delineate, and whom the readers of his book will be glad to welcome. But in a drama the story-teller is debarred from these wanderings from the straight and narrow road, and he must, perforce, control his enthusiastic imagination, compelling it to do its work within the rigid limits of the artfully devised framework of the plot.

In other words, character is all-important in prose fiction, and the ultimate fame of the novelist depends upon his power of endowing his creatures with life, and upon his ability to let them obey the laws of their being before our eyes. This must the playwright also achieve; but he has the added duty of relating his characters intimately to the main action of his drama. Now, the novelist is under no obligation of this sort; he appeals not to a crowd seated before a stage, but to the solitary reader in the study; and experience shows that solitary readers do not insist upon the solidity of structure in a novel which the same individuals desire and demand when they betake themselves to the theater. The novel-reader may be satisfied by characters who do not know their own minds, and who are merely exhibited and put through their paces, without having any vital relation to the story, even if there is anything which can fairly be called a story—and in some novels of high repute, in Sterne's 'Sentimental Journey,' for example, and in Anatole France's 'Histoire Contemporaine,' each of them extending over several volumes, there is little or no story, no main thread, no pretense of a plot.

Here, then, is the fatal difference between a novel and a play; a novel may have a plot, but a plot is not necessary, and it can get along with a minimum of story; whereas a play must have a plot, skilfully articulated, even if the skeleton is beautifully covered; it must have a story peopled by persons knowing their own minds, a story set in action by a dominating will, which determines the successive episodes of the action. As the making of a plot, as the putting together of a supporting skeleton of action, calls for dexterity of workmanship, for ingenuity of resource, for adroitness of construction, for the most careful consideration of the means whereby the end is to be obtained, two heads are often better than one, because the partners have to talk the thing out to its uttermost details before they decide upon the straight line which is the shortest distance between two points. The technic of play-making is more exacting than the technic of novel-writing, and it requires imperatively the exact and detailed plan which Joubert held to be hampering to enthusiasm and imagination. Scott, for example, as he tells us himself, began more than one of his novels not knowing what he was going to put into it, and not knowing from day to day, as he was writing, what his ultimate goal would be. But no playwright, however happy-go-lucky in his tendencies, has ever dared to begin a play before he knew with absolute certainty how he intended to end it. In the drama we insist upon a straightforward and unswerving action; the end is implied in the beginning, and the beginning is only what that end makes necessary.

As the technic of the drama is exacting, it needs to be acquired by a period of apprenticeship; and here is another of the indisputable advantages of collaboration. The more inexperienced of the two collaborators is taken into the studio, so to speak, of the more expert, and he thereby learns the secrets of stage-craft in the best possible way, by applying them under the direction, or at the suggestion and by the advice, of an older practitioner, to whom they have become so familiar that they are a second nature, as it were.

Collaboration is the best conceivable school for young playwrights. It is impossible to overestimate the influence of Scribe's multiplied collaborations upon the drama of France in the mid-years of the nineteenth century; and almost as potent, because almost as wide-spread, was the influence of the many collaborations of the elder Dumas. Most of those who were the temporary partners of Scribe and Dumas were subdued to their more powerful associate, and contributed little or nothing beyond their fundamental suggestions for the several plays, and their incidental suggestions as to details of the working-out. That is to say, most of the plays signed by Scribe and Dumas in partnership with others have a close similarity to the plays they signed alone. But from this generalization we may except 'Adrienne Lecouvreur' and 'Bataille de Dames,' in which Scribe had Legouvé for a partner, and in which we find a greater richness of character delineation than in any of the pieces that Scribe composed alone, as we find also a greater dexterity of construction than in any of the pieces that Legouvé composed alone.

To the fact that 'Milestones' was written by Mr. Arnold Bennett and Mr. Edward Knoblauch in conjunction, and to the friendly discussion due to their working together, we may credit the superior stage-effectiveness of this play over the 'Kismet,' which Mr. Knoblauch wrote alone, and over the 'Great Adventure,' for which Mr. Bennett was solely responsible. To the composition of 'Milestones' each of these two authors, the American and the Englishman, brought his special qualifications, each of them not only stimulating but supplementing the other. So we find the most famous French comedy of the nineteenth century, the 'Gendre de M. Poirier,' a better piece of work, more equably balanced than any play written alone by either Augier or Sandeau.

It is scarcely necessary to say that there is little profit in a partnership for play-making when both of the associates are equally inexpert, or when they were both possessed of wrong notions about the art of the drama. In the former case we have the blind leading the blind, and the most lamentable example of this is the long forgotten 'Ah Sin,' which Bret Harte and Mark Twain combined to compose that C. T. Parsloe could impersonate the Heathen Chinee. In the latter case we have not only the blind leading the blind, but a perverseness in going the wrong way, intensified by the complete sympathy between the two associates; and the most lamentable example of this is the 'Deacon Brodie' of Robert Louis Stevenson and William Ernest Henley, who not only were ignorant of the modern technic of the drama, but who ignored it of set purpose, deliberately going up a blind alley despite the plain sign that there was no thorofare.

Yet Stevenson, at least, perceived clearly enough what ought to be the more evident advantages of collaboration, that it focused "two minds together on the stuff," thus producing "an extraordinarily greater richness of purview, consideration, and invention." Collaboration will probably always produce a greater richness of invention, since each of the partners is likely to stimulate the other, their two minds striking sparks like flint and steel. But it can produce a greater richness of consideration only when each is willing both to yield and to oppose. Neither must yield too easily; each of them must stand out for his own suggestions; and each of them must insist on weighing and measuring the suggestions of his ally. If they are too sympathetic, if their two hearts beat as one, then the advantage of their having two heads is diminished. If the two partners always think alike, then there will be no greater richness of purview.
