The hall for the dancing was created by taking down the board partitions that separated three of the class-rooms; and hanging the walls with cheese-cloth to hide the old stains and paint-marks, and with pictures by the instructors. There was a piano for the music, and around the wall rough benches were put, with rugs over them to save the ladies' dresses. The effect was very pretty, with palettes on nails, high up, and tall flowers in vases on brackets, and a life-study in plaster by one of the girls, in a corner of the room. It all had the charm of tasteful design yielding here and there to happy caprice; this mingling of the ordered and the bizarre, expressed the spirit, at once free and submissive, of the place. There had been a great deal of trouble which at times seemed out of all keeping with the end to be gained, but when it was all over, the trouble seemed nothing. The exhibition was the best the Synthesis had ever made, and those who had been left out of it were not the least of those in the masquerade; they were by no means the worst dressed, or when they unmasked, the plainest, and Charmian's favorite maxim that art was all one, was verified in the costumes of several girls who could not draw any better than she could. If they were not on the walls in one way neither were they in another. After they had wandered heart-sick through the different rooms, and found their sketches nowhere, they had their compensation when the dancing began. The floor was filled early, and the scene gathered gayety and brilliancy. It had the charm that the taste of the school could give in the artistic effects, and its spirit of generous comradery found play in the praises they gave each other's costumes, and each other's looks when they were not in costume. It was a question whether Cornelia who came as herself, was lovelier than Charmian, who was easily recognizable as Cleopatra, with ophidian accessories in her dress that suggested at once the serpent of old Nile, and a Moqui snake-dancer. Cornelia looked more beautiful than ever; her engagement with Ludlow had come out and she moved in the halo of poetic interest which betrothal gives a girl with all other girls; it was thought an inspiration that she should not have come in costume, but in her own character. Ludlow's fitness to carry off such a prize was disputed; he was one of the heroes of the Synthesis, and much was conceded to him because he had more than once replaced the instructor in still-life there. But there remained a misgiving with some whether Cornelia was right in giving up her art for him; whether she were not recreant to the Synthesis in doing that; the doubt, freshly raised by her beauty, was not appeased till Charmian met it with the assertion that Cornelia was not going to give up her art at all, but after her marriage was coming back to study and paint with Ludlow.
