The exhibition and sale of war posters by Mrs. Fiske Warren, in Copley Hall, will begin on Thursday and last the rest of the week. The proceeds of the sale will be used to buy wool for the Belgian refugees who have collected in London. The members of the University who have volunteered have been assigned hours, six at a time, to help at the exhibition, which will be open on Thursday evening from 8 to 11 o'clock and on Friday and Saturday from 10 A. M. to 6 P. M.

During the last two days the exhibition is open free. On Thursday, admittance will be only by ticket. These are now on sale at the Co-operative Branch store at $1.00 each.
