"I'm all right," she said.

"Yes, it's hotter than usual to-day," said the handkerchief-holder, fanning vigorously.

"Why do they have it so hot?" asked poor Betty.

"Because of the model, of course. Poor thing! she hasn't got a nice blue gown and a pinky-greeny pinafore to keep her warm. We have to try to match the garden of Eden climate—when we're drawing from a girl who's only allowed to use Eve's fashion plates."

Betty laughed and opened her eyes.

"How jolly of you to come out after me," she said.

"Oh, I was just the same at first. All right now? I ought to get back. You just sit here till you feel fit again. So long!"

Her easel was there, and her half-rubbed out drawing—No, that was not her drawing. It was a head, vaguely but very competently sketched, a likeness—no, a caricature—of Betty herself.

She looked round—one quick but quite sufficient look. The girl next her, and the one to that girl's right, were exchanging glances, and the exchange ceased just too late. Betty saw.
