THE Class-Day Committee have fixed the order of exercises for Class Day. The exercises at Sanders Theatre will be opened with prayer by Dr. Peabody, at half past eleven o'clock. Then will follow the Oration, the Ode, and the Ivy Oration. There will be dancing in Memorial Hall from two o'clock until five, and at half past four the exercises at the Tree will begin. Spreads and teas will probably occupy the spare hours, and in the evening Memorial Hall will be opened for dancing from eight until eleven. Every Senior is entitled to twenty tickets to the Yard, seven to the Tree, six to Memorial Hall (to admit one gentleman and two ladies), and five to Sanders Theatre. Tickets are now ready, and can be obtained at 10 Weld, every day, from twelve till one P. M., and at 25 Holyoke Street, from two till three P. M. The Committee, at the request of the Corporation, have decided to give tickets to the Yard and to Memorial Hall to Seniors in other departments of the University, on condition of their paying five dollars, which is half the regular Senior assessment. The fear, which many persons entertain, that there will be a terrible crowd at all the exercises, seems to be unfounded. It is not likely that the graduating classes of the Bussey Institution and of the Dental School will flock to Cambridge in overwhelming numbers, and should large delegations come to Cambridge, they may be certain that the Yard will be large enough for them.
