Stevenson was here making the mistake which so many men of letters make when they turn to the theater. He was going upon the theory that the drama is made literary, not from within, by observation and imagination and sincerity, but from without, by the application of fine speeches. His speeches were fine, no doubt, even tho they were not in keeping with that special kind of play when it had been alive. But as it happened, that kind of play was dead and gone, and no injection of oratory would bring it to life again. And here the Scotch story-teller failed to profit by the example of the French poet whose romances he had so sympathetically studied. Hugo had also a gift for oratory and a talent for fine speeches; but when he yearned for theatrical success he went to the most popular playhouses where the plain people gathered, and he adopted as his own the formula of play-making which was proving its value in these boulevard theaters. This was not in itself much better than the formula Stevenson borrowed and did not trouble to understand--indeed, the two are not unlike. But Hugo had made his choice half a century before Stevenson; and when he made it he was taking possession of the very latest fashion. Hugo's formula is now fallen out of mode, yet his plays have accomplished their threescore years and ten. It was Hugo who declared that there are three classes of theater-goers whom the playwright must please: the crowd that demands action, the women who wish for emotion, and the thinkers who seek for character. And it was Hugo's early rival as a play-maker, the elder Dumas, who asserted that the only rules he knew for success upon the stage were to make the first act clear, the last act short, and all the acts interesting. A dramatist who shall accept the formula which has been found satisfactory by his immediate contemporaries, and who shall succeed in making all the acts of his play interesting alike to the crowd, to the women, and to the thinkers, will be very likely to achieve literary merit without striving for it specifically.
