In accordance with the announcement in yesterday's CRIMSON, tickets to the opera may be obtained at one-half the regular price by applying to the opera ticket committee of the Student Council, which will hold office hours at Phillips Brooks House at the following times: Monday, Wednesday, and Friday, 8.30 to 9 A. M., 10 to 11 A. M., and 5.30 to 6 P. M., Tuesday and Thursday, 8.30 to 10 A. M. and 11 A. M. to 12 P. M. All applications must be made in person, and it should be understood that no seats are recovered by the committee. A man who makes use of the arrangement has exactly the same chance of securing seats as any one else, and only the price of the ticket is affected by the system. The arrangement does not include Saturday night performances, and is limited to $1, $1.50, and $2 seats, which may be secured at 50 cents, 75 cents, and $1 respectively.
