Mr. Blair was a brusk man and he stood for very little of this.

“If that girl is not amenable to discipline, Miss Allister, excuse her from your chorus. We cannot be delayed. Mr. Stratford himself and the ladies of the committee are downstairs listening in on this rehearsal. If it is not soon perfect I am afraid we will have to substitute something else for your chorus.”

Most of the other girls were excited by this threat, and they promised to be careful. But Belle and Sally Moon pouted and shuffled their feet, and otherwise behave like naughty children instead of like high school young women. Miss Allister tried to hide their impoliteness; she knew them well. It was evident, however, that the rehearsal was going badly and that Mr. Blair was disappointed.

Jessie and Amy stood by anxiously, awaiting their turn to sing and recite. It was very warm in the sending room, although some attempt had been made to ventilate it. But the heavy curtains hung all about kept out the air as well as keeping in the sounds.

The singers faced a battery of receiving horns. The sound amplifiers were out of sight. Indeed, there was little mechanism to disturb the attention of the performers. The girls should have sung just as easily and nicely as they did in the school audience hall.

But the rehearsal continued to go badly. Jessie got as nervous as though she had been one of the chorus herself. And this was bad for her; for soon, she knew, she would be called upon to sing her own short ballad.

CHAPTER XVII
AN INVITATION TO A PARTY

Superintendent Blair suddenly put up his hand and stopped the chorus in the middle of its second number. He looked very stern but he spoke composedly enough to Miss Allister. She was in a flutter of excitement.

“Let them rest awhile,” said Mr. Blair, bruskly. “They are not doing well; nowhere near good enough to broadcast from Stratfordtown. We pride ourselves here, Miss Allister, on sending out good stuff.

“Perhaps they will do better later. Let them rest. Meanwhile, we will try out these others. Who is first? Miss Norwood?” He looked from the paper in his hand to Jessie.
