1y.THE Theatre of Arts and Letters will give its first public performance at the Columbia Theatre to-morrow (Thursday) evening at 8 o'clock. The play will be Frank Stockton's "Squirrel Inn," a comedy in four acts, as amusing as Mr. Stockton always is and as good literature. This play was produced in New York at the second private subscription night of the Theatre of Arts and Letters, and was received by that very exacting and critical audience with delight. It is now to be offered to the public under the ordinary theatrical conditions. The company will include the beautiful young actress whom Mr. Booth had engaged to succeed Minna Gale as his leading lady before Mr. Barrett's death and his own illness changed his plans, Mr. Paul Arthur, Mr. MacKay, Miss Netta Guion are others of the company. The stage management is under the direction of Mr. Robt. M. Eberle, formerly stage manager for Mr. Booth and Mr. Barrett. Seats on sale at Columbia Theatre, the Brunswick Hotel and the usual agencies.
