Maturin’s new tragedy, ‘Manuel,’ appeared on Saturday last, and I am sorry to say that the opinion of Mr. Gifford was established by the impression made on the audience. The first act very fine, the rest exhibiting a want of judgment not to be endured. It was brought out with uncommon splendour, and was well acted. Kean’s character as an old man—a warrior—was new and well sustained, for he had, of course, selected it, and professed to be—and he acted as if he were—really pleased with it. But this feeling changed to dislike after the first night, for he then abused it, and has actually walked through the part ever since, that is to say, for the other three nights of performance, for they do not act on Wednesdays or Fridays, and this night the performance is changed to ‘Lovers’ Vows.’ I met Geo. Lamb on Tuesday, and he complained bitterly of Kean’s conduct, said that he had ruined the success of the tragedy, and that in consequence he feared Maturin would receive nothing. The expense to the managers must have been very great, and it will complete, I suspect, the ruin of Drury under its present directorship, and so I rejoice that your name appears not amongst them. I send you the first act, that you may see the best of it. I have undertaken to print the tragedy at my own expense, and to give the poor Author the whole of the profit.
