Could he fix it in time to get her to the aviation field before the race?

Well, that depended partly on whether she would go away and not bother him until breakfast.

Pauline could, and she certainly would refrain from bothering him. Never before had Harry found her a bother, nor, for that matter, had any other man in her recollection. Out she went, with more color than usual in her pink cheeks and the light of battle in her eyes.

"By George, I've got to play my cards carefully," thought Harry, as he contemplated the runabout. It was evident that he had designs on the health of the two-seater also. But he felt the necessity of subtlety in this case. He could not assassinate it boldly by tearing out a vital organ as he had done to the bigger car. This runabout must die a slow, lingering death. How was he to do it? His first idea was to weaken the tires and invite "blowouts" on the road. But this could not be done with certainty, and some kind friend might supply him with new tires.

A more promising idea was to drain the engine of its oil, knowing that sooner or later the pistons would run dry and stick. Such a proceeding would ruin the engine, and Harry was too good a mechanic to spoil a first rate engine, especially one built by his father. He would as soon think of hamstringing a faithful horse. A better plan soon came to him and put him into action. It soon had him flat on his back under the car, boring a hole in the bottom of the gasoline tank. When the life-blood of the car began to trickle out in a stream he stopped the hole with a small wooden peg.

The young man now frowned at the only remaining vehicle which had, not received his attention, Owen's motorcycle.

Harry went to the hose used for washing down the cards and collected a little water in the palm of his hand. With the other hand he removed the cap from the motorcycle's tank and allowed two or three drops of water to mingle with the gasoline.

This done, Harry let down his sleeves, washed his hands, and sauntered in to breakfast, with the unwelcome announcement that the big car was, for the day at least, beyond human aid.

There was a flicker of suspicion in Owen's sallow face at the news. He wondered if Harry had disabled the touring car that he might ride alone with Pauline.

"I am afraid," said Harry, quietly, "that you will have to ride in the runabout alone with me, Polly. It's rather hard on Raymond, but I guess he must go on his motorcycle or by train."
