Some days ago the Harvard Classical Club issued an invitation to the Glee Club and Pierian Sodality to give a concert for the benefit of the American School of Classical Studies at Athens. It is well known in literary and scientific circles that this school is doing much toward giving American classical scholars a chance to take a position in the world of archaeological and philological research. The fact that Dr. Charles Waldstein has been appointed to the directorship of the school, on condition that a fund of $100,000 is secured, is also well known. It is toward furthering this end that Harvard's musical societies have generously consented to give a concert on Friday, March 18, in Horticultural Hall. Boston. The Banjo Club has also kindly volunteered its services, so that the programme will be sufficiently varied and attractive. A number of prominent ladies and gentlemen in Boston and Cambridge will act as patrons and patronesses of the concert. Tickets can be had of them, at Sever's and at the Vendome in Boston, as well as of members of the Classical Club, Further announcement of the programme and so forth will be published shortly.
