four o'clock
A novel feature , much patronized by the Juniors , was a Surprise Packet table . All kinds of tempting little articles were wrapped up in gay tissue paper , and purchased somewhat on the system of `` buying a pig in a poke '' , an arrangement that at any rate afforded great amusement when the parcels were untied . The stalls soon began to exhibit a welcome bareness , and the stall-holders felt the fullness of their bags with satisfaction . Towards four o'clock everybody showed a tendency to migrate in the direction of the café chantant . This had been arranged in the largest of the classrooms . Tea was served at small tables while a concert proceeded , the guests being expected to retire after about ten minutes , so as to make room for others . Helen Roper had got together quite a good programme .
