IN speaking of the boat-club theatricals recently given in New York, we should have mentioned the name of Mr. Nathaniel Curtis in connection with Mr. Sherwood's. The latter, it is true, composed a number of the songs, and contributed to the success of the performance by his acting; but the credit of having originated the undertaking, altered the play, and selected the company, belongs to Mr. Curtis. The omission was accidental, as it is well known in Cambridge that Mr. Curtis, though not occupying a prominent position at rehearsals, was the heart and soul of the enterprise.
