The initial performance of "L'Aventurier," the Cercle Francis play, will be given in Agassiz House, Cambridge, on Monday evening at 8 o'clock. The play will be produced a second time at the Copley Theatre, Boston, next Wednesday afternoon at 2.15 o'clock. Mr. Edousard D'Armand, of the Conservatoire Nationale de Paris, who coached the casts of the Cercle's plays last year, has directed the rehearsals for the production this year. As usual, members of the Radcliffe Cercle will take the women's parts. Tickets for both performances are on sale at Herrick's and the Co-operative Branch. The prices are 50 cents, 75 cents, $1.00 and $1.50.
