The driver turned and grinned. He was a not-over-clean youth, and his hair was badly in need of a barber's attentions, but he was evidently good-natured. The car, which was an old one and had undoubtedly seen much better days, swung around and headed back toward Thacher School and the football field. The youth talked to them over his shoulder.

"She's hard to start," he said, "when she's been standing, but she can go all right. You wait till we're out of town and I'll show you. I got to go over to Wharton to get Mr. Cumnock."

"Who's he?" asked Amy disinterestedly.

"He runs the Commercial House. He comes out from New York on the express and I go over and get him."

"Oh, is this his car?"

"No, it belongs to Sterry, the liveryman. I drive for him. It's been a good car in its day, but it's pretty old now. Runs pretty well, though, when it's in shape."

"I hope," said Clint, "it's in shape today."

"Sure. I was two hours fixing it this morning. Now I'll show you if she can go."

He did and she could! They passed the school and the football field at a thirty-mile clip and, a little further out of town, hit it up still faster. Clint and Amy bumped around in the tonneau like two dried peas in a pod. The engine was by no means noiseless and from somewhere under their feet there came a protesting grind that nearly drowned their efforts at conversation. Not that that mattered, though, for they were going too fast to talk, anyway. At first they were a bit uneasy, but presently when they found that the car did not jump into a ditch or vault a fence, they got over their nervousness and thoroughly enjoyed the well-nigh breathless sensation. The driver lolled back on his spine with a nonchalance that aroused Clint's admiration and envy. He wondered whether he would ever own a car and be able to go dashing through the scenery at forty miles an hour like this. And he was still wondering when something happened.

It happened so quickly that it was all over before it had begun. At least, so Amy declared afterwards. The car, which fortunately had decreased its speed to negotiate an abrupt turn in the road, suddenly shot down a slope at the left, turned around once and stopped with a disconcerting abruptness, its radiator against a four-inch birch tree. Clint and Amy picked themselves from the bottom of the tonneau and stared, more surprised than frightened. Behind them, on the level road, a wheel--present investigation showed that it was the forward left one--was proceeding firmly, independently on its way! As they looked, open-mouthed, it began to wobble, as though doubtful of the propriety of going off on its own hook like that, and finally, after turning around several times, like a dog making its bed, it subsided in the dust.
