i lie engagement of the Emma Abbott Grand English Opera Company to appear at the Opera House, Friday evening, April 13th, will be generally looked upon as the eilief event of the amusement season. The degree of popularity and favor in whieh Miss Abbott is held in this citv give8 assurance that she will be welcomed by a large audience. She will appear under more favorable conditions than ever before, by reason of the fact, that she is singing in far better form this season than hitherto, and the further fact that she is aided by the largest and best company that has ever giren English opera in this country. In numbers and excellence it is far in advance of any similar organization and its work is every where pronounced artistlc and complete. The names of such eminent artista as Madame Rosewald, Lizzie Annandale, Marie Hindle, Kate Hoyt, William Castle.Valentine Fabrini, Alonzo Stoddard, Wm. Broderick, and others equally prominent, give guaranty of the excellence of the organization as to its principáis. The chorus is large and well trained, and the orchestra is composed of fine iriusicians. Flotow's ever popular " Martha," will be presented here, and will be given by a splendid cast, and with the aid of everything requisite in a flrstclass operatic presentation. It is in this opera that Miss Abbott'a exquisite singing of the " Last Rose of Slimmer" is heard. The ent' rtainment will certainly be a thoroughly enjoyable one, and Miss Abbott and her company may feel assured that they will be greeted by a crowded house. The advance sale will begin Monday monling, the 9th instant, and early applicattons for seats will be advisable. The two plays which Prof. DePout is to present next Wednesday are exciting great interest in social circles about town, They are written with the most sparkling wit and must deride the most solemn countenance. "In Woodcock'slittleGame" we find an old bachelor who, tired of cutting capas, inarries to settle down, but is obliged to run a " second inning" by nis mother-in-law who is over.fond of the "light fantastic toe." Yet Woodcock srets the better of her and gains liia point. lei l'on parle Francais is an expositiou of a worthy Biiton who wants toc.itch lodgers of digtinction and inake them pay fancy prices, by putting the sign, "Frenen spoken here" at bis door. He therefore learns French before breakfast but on the first day he puts up hU sign he falla into such a series of troubles, domestic opposition, foreign invasión, that he gets almost distracted and abandons all idea ever to "parier francais," and the ciowning interest of the evening will be found in a second appearance of Miss Bessie Dunster and Nellie Ames who have so delighted the Ann Arbor audiences at "On the Boards'' by their dancing. Mr. Kelly Jr. has prepared for the coming occasion an entirely new set of figures which, we are told, will cxcell the former, and now it may be 8aid that the characters will therein be interpreted by home talent; but home talent which is worth inany a professional. Surely after applauding Mr. J. M. Zane and W. B. Chambeilain who by their excellent rendering of Demea and Mlcio in Terence's Adelphoc brought us back to the days of ancient Rome, and after witnessing the perfect marnier in which Miss Bessie Hunt and Mr. E. C. Calcyron interpreted the French Comtesse and the Jean of Racine's Les Plaideurs, we ought not to have any fear of any thing but dying with laughter. In short we can only say, don't fail to go.
