Such as we have described are the emotions which are always produced by the play now under consideration, when it happens to be properly represented. Fortunately or unfortunately as it may happen, the play is so constructed that almost every part in it contributes largely, according to its kind, to the interest of the piece. Every person of the _oppressed_--the Peruvians, even down to the blind man and the little boy, are made by the poet to produce a large share of the general effect. For this reason it is a piece which taxes a manager highly, calling for a variety of excellent talents in the actors. It is not one of those plays which satisfy the mind and from which we come home contented, if two or three characters are well done. The play of Pizarro is a lifeless body when compared with what it ought to be, if _all_ the high Peruvians at least, are not well performed. In the movement of a watch every small wheel and every little rivet is as necessary to the general effect as the mainspring. So Las Casas, Orozimbo, the blind man, and the blind man's boy, are as necessary not perhaps to the mean progress of the fable (but to that effect, that necromantic influence upon the feelings, that penetrating moral which alone can render a play useful as well as delightful) as is the character of Rolla. It may appear a singular avowal, yet being truth we will not withhold it, that having witnessed the performance of this play many times in England and America, we have never yet seen it performed to our _perfect_ satisfaction. Kemble was great in Rolla, but the feebleness of his voice was severely felt by the audience in the celebrated speech of the Peruvian to his soldiers. That speech has been the stumbling block of most actors we have seen. Hodgkinson, who in other respects was unexceptionable, rather failed in it. Throughout the whole character, Mr. Wood preserved a very equable tenor of acting. He had neither the rich beauties nor the striking defects of others. He evinced considerable judgment, but at times powers were evidently wanting. Mr. M'Kenzie supported Pizarro well, and showed that he possesses abilities to support it better. It appears to us that this gentleman's physical powers are sometimes subdued by an over-scrupulous chasteness. In his answers to Elvira's solicitations on behalf of the unhappy Alonzo, he did not, we think, sufficiently mark all the feeling and emotions of the tyrant. Pizarro is stung with jealousy as well as rage; not so much the jealousy of love as of infernal pride; but both rage and jealousy are mastered by triumphant insolence and contempt. The utterance therefore of his laconic decisive sentence, "He dies," should be marked with a triumphant sneer as well as malice. Mr. Warren did ample justice to the venerable Las Casas.
