This afternoon there is to be given at the Hollis Street Theatre a three act Comic Opera written by Mr. Cory, a Boston amateur. This opera is said to have made a hit when given previously some years ago. The scene is laid on the renowned shores of Cape Cod when unusual visitors in the shape of pirates and smugglers, cut capers and make love. The songs are bright, the wit not buffooning, and the music much above that of the average Comic Opera Perhaps the greatest attraction is that the leading parts are all taken by prominent singers, such as Miss Edmunds and Miss Starkweather, Messrs. Babcock, Brine, Fessenden and Bartlett. Mr. Cary has been induced to give this one performance for the aid of the Marine Biological Institute, a struggling summer school which has already proved its usefulness. Tickets may be procured at the Co-operative or at the theatre.
