The third concert of the Choral Jnion series will be given by the Choral Union, assisted by an orchesra of thirty pieces, in University Tall, next Friday evening, March 3th. At eight o'clock sharp the oors will be closed and no one will )e admitted from that time until fter the overture to "Christoforus" ïas been given. At this point a short pause will be made in order to permit those who may have come in late to get seats. Then if necessary to secure those present from interruption, the doors will be closed again. It is hoped, however, that everyone will be considérate enough to make the last precaution unneccessary. It may not be amiss to state again that no one can obtain single admission tickets to these concerts except those holding season tickets. Season tickets may be had at any time from Professor de Pont or Professor Wines for the sum of two dollars; and this price will not be reduced as the season grows shorter. Single admission tickets for this concert will cost seventy-five cents, and for the Boston Symphony concert, which is the next after this in the course, they will cost one dollar. Later in the season the "Redemption" will be given and single admission tickets will cost seventy-five cents. Thus it will be seen that for anyone wishing to attend these three great concerts, the cheapest way will be to buy a season ticket, although two of the concerts on the course have already been given.
