The Girl Aviators' Motor Butterfly Part 23

"Yes, we had some conversation with him this morning," laughed Roy; "but to return to the spark plug; it's a good thing we carry extra ones."

"But we don't!" cried Jimsy, in a dismayed tone.

"What! you had a supply in a locker on your machine."

Jimsy looked confused.

"I've got to make a confession," he said.

"You didn't bring them!" cried Peggy.

"No, the fact is I--I forgot."

Jimsy looked miserably from one to the other. Here was a quandary indeed. It might prove hard to get such a commodity as a spark plug in Millbrook.

CHAPTER XVIII.

IN SEARCH OF A NEW PLUG.

It was while they were still discussing the situation that the automobile with Jake at the wheel and Miss Prescott and The Wren in the tonneau, drove into the grounds. What a difference there was in the child since her benefactors had fitted her out! She looked like a dainty, ethereal little princess instead of the ragged little waif that had been rescued from the gipsy camp.

But the minds of our young friends were now intent on different matters.

Time pressed. The alt.i.tude flight, in which Jimsy had planned to take part, was to be the first thing on the program. If anything was to be done about reequipping the _Dragon_ it must be done quickly.

"Tell you what," said Roy suddenly, "we'll get into the car and drive back to town. It won't take long and maybe we can dig up an extra one some place."

"If we don't I'm out of it for keeps," groaned Jimsy; "oh, that Kelly.

I'd like to punch his head."

He doubled up his fists aggressively; but, after all, what chance had he to prove that Kelly had actually damaged the plug. If confronted the man would have probably denied all knowledge of it. n.o.body had actually seen him do it, so that positive proof was out of the question. No, they must repair the damage as best they could.

But Roy determined to have the machines closely guarded. The situation was explained to Miss Prescott, and while she and her small protege took seats in the grand stand Jake was detailed to guard the aeroplanes. This done, the boys got into the machine and prepared to start for town. But the girls interfered.

"Aren't you going to take us along, you impolite youths!" cried Bess.

"Oh, certainly, your company is always charming," returned Jimsy, with a low bow.

"Of course it is, but you wouldn't have asked us to come if we had not invited ourselves," declared Peggy vehemently.

"How can you say so? Our lives would be a dry desert without the girl aviators to liven things up," declared Jimsy.

"Jimsy Bancroft, if you are going to get poetical you'll leave this car," cried Jess.

"That's just it," declared Jimsy, "girls can cry their eyes out over romantic heroes, but when a regular fellow starts to get 'mushy' they go up in the air."

Amidst the chorus of protestations aroused by this ungallant speech Roy started the car. Swiftly it sped out of the grounds; but not so swiftly that the keen eyes of Lish Kelly did not see it.

He called Herman Le Roy, the Cuban aviator, to him.

"Le Roy, you are not in the alt.i.tude contest," he said, "hop in my car with me and we'll follow those kids. They're up to something."

The Cuban looked at him and smiled, showing two rows of white teeth under his small, dapperly curled mustache.

"I think, Senor Kelly, you have been up to something yourself."

"Well, you know what I told you. We want that five-hundred-dollar prize, Carlos, and by the looks of things if we don't do something those kids are likely to get it."

"They have fine machines," agreed the other.

"Yes; and they are equipped with a balancing device that makes them much more reliable than ours."

"A balancing device!" exclaimed the Cuban, as the two men got into the car, a small yellow runabout of racy appearance.

"That's what I said, and it's a good one, too. I read an account of it in an aviation paper; but the description was too sketchy for me to see how the thing was worked."

"Those boys must be wonders."

"I'm afraid they are. That's why we've got to be careful of them. But I've got a plan to fix them, the whole lot of them."

"What is it?"

"I'll tell you as we go along."

As the car rolled past the group of aeroplanes with Jake faithfully standing guard over them, Kelly hailed him in a suave voice.

"Any idea where the young folks have gone?"

Jake, who had no idea that Kelly had a sinister motive in asking the question, replied readily enough.

"Yes, they've gone into Millbrook to get another spark plug. Something happened to one of the plugs of that red machine yonder."

"All right. Thanks."

Kelly drove on.

"Do you know what happened to that plug, Carlos?" he asked, as they reached the open road and bowled forward at a good speed.

"I've got a pretty good guess. It was not altogether an accident, eh?"

"An accident, well, it was, in a sense. I happened to be near that machine with a monkey wrench and in some way was careless enough to let it put that plug out of business."

Both men laughed heartily, as if Kelly's rascally act had been the most amusing thing in the world.

"You are a genius," declared Le Roy.
