"When do we start?" she asked, abruptly. Don't think for a minute she was acting under her natural impulse. If she had been, she would have thrown her arms around Polly and been very foolish; but she was trying to act the way she knew Bob would have—without fuss. She knew how Polly hated a fuss.

"Now, the horses mustn't catch cold and McDonald ought to see a doctor," Polly said. "Tell them to get in, will you? and, Lo," she added with a grin, "pray hard going down hill. I have my doubts about the brake."

When they were all in, Miss Crosby said:

"I think we better take McDonald to the hospital."

Polly nodded: "All right, I know where it is."

The horses, sure of themselves by now, and confident in their driver, behaved very well.

At the outskirts of the village, they drew up before the little white hospital, and Betty jumped out and rang the bell. A nurse answered it. In a few minutes they were carrying McDonald in on a stretcher.

As they started up the steps with him, he called: "Miss Polly!" in a shaky voice.

Polly jumped down from her seat, and went to him.

"I'm done for," he said, slowly, "and you're a very wonderful girl. You stopped those horses, you did, and I— I couldn't—" He broke down.
