But the slender ones they found proved unavailing. Automobiles are all too common to attract attention unless there is something unusual about them. And Cora's car, while it was a fine one, was not unusual enough to call for special notice.

The number on the license plates had been given to the police and constables, but it would have been a comparatively easy matter for the thieves to change the number or rub oil on and let dust acc.u.mulate until it would have been all but indecipherable. Then, too, persons seldom notice the number on a car unless there has been some accident.

"It just seems to have disappeared," declared Cora at the close of the day, when a long tour and many inquiries had resulted in nothing. "I just wish I had hold of those two fellows!"

"It _is_ provoking," agreed Belle. "Let's stop at the tea room and see if they've heard anything more there."

The girl at the cash register, the young lady manager, and the colored maid who had waited on them before greeted the three pretty chums smilingly as they again entered the pleasant tea room of Ye Olde Spinning Wheel.

"Were your tickets for the play all right?" asked Cora as the manager stepped over to inquire if everything was to their liking.

"I haven't used them yet. They are for this week Friday. Oh! I'm sure they're all right. Some of my friends bought tickets from the same fellows for the same night and they are next mine."

"Those chaps must have planned for a regular theatre party," observed Belle.

"Have you had any trace of your car yet?" the cashier asked, as Cora went up to pay the check.

"No, I'm sorry to say, I haven't."

"If you don't get it soon, Cora," said Belle, "you'd better plan to use ours to go to Camp Surprise."

"Oh, we're going in the motor boat," Cora said. "I didn't tell you, but mother learned that the roads around the camp were so rough that it would certainly spoil a car to take it to camp, so I wouldn't take mine, anyhow."

"Camp Surprise," repeated the pretty cashier. "That sounds interesting."

"I hope we don't find it too much so," returned Belle.

The plans for going to live at the bungalow with the odd name, which was situated in the mountains some miles west of Chelton, had been talked over at length, and an earlier trip than the one originally decided on had been voted for.

"Going in the motor boat! How nice!" cried Bess, as they went out of the tea room. "Then it doesn't matter about your auto, Cora-I mean, of course-oh! I don't mean that!" she cried, blushing. "Of course you want it back--"

"Well, I should say I do!" exclaimed Jack's sister with mock indignation.

"I mean we won't have to wait until you get your car back before going to Camp Surprise," Bess went on.

"No," agreed Cora. "That won't delay us."

"And now don't you think you ought to tell us why the camp where we are going to spend most of the summer has such an odd name?" asked Belle.

"I've been meaning to this long while," a.s.sented Cora, "but so many things have happened that I didn't get to it. Come on, let's sit out here on the porch, where it's so nice, cool and shady, and I'll tell you all I know."

"You couldn't, Cora, dear-not in the limited time at our disposal," said Belle, languidly sinking into an easy wicker chair. "You know too much."

"Thank you. I believe this was my treat, so now we're even. But I meant all I know about Camp Surprise."

"First, how did it get its name?" asked Bess.

"Because of the surprising things that happen there."

"Happen-happen?" queried Belle. "Do you mean they still happen?"

"Well, so mother said," observed Cora.

"Bur-r-r!" shivered Bess, with a hasty glance over her shoulder. "I'm not so sure I want to go there."

"Nonsense!" cried Cora. "If there's a ghost we'll lay it-whatever that means."

"Oh, Cora! Ghosts!"

"Oh! I don't mean that, exactly. It isn't so bad as that. The worst things that have happened are that things in the bungalow seem to be upset and misplaced without reason."

"Upset? Misplaced?" murmured Belle.

"Without reason?" added her sister.

"Oh! perhaps I am making a mountain out of a molehill," confessed Cora.

"This is how the matter stands. Up in the mountains are a number of camps, cottages, bungalows-what you like-which belong to a development company. The bungalows and camps are rented, furnished, to whoever wants them. Camp Surprise, where we shall have a good-sized bungalow to live in, is one of the best of these resorts. It is about five miles in from the Towanda river, which is what the Chelton is called up state, and it was going up the river that I planned to use the motor boat."

"How do we get over the five miles?" asked Bess.

"By buckboards over a mountain road. That's why we won't need the autos.

Of course we could use a car, but as long as mine is still among the missing we won't make any such plans. Camp Surprise is right on the edge of a stream which is quiet enough in dry weather, but a torrent when there's a heavy rain. And there's a little lake and a waterfall near the bungalow."

"That sounds lovely," remarked Belle.

"It is lovely," a.s.serted Cora. "I've seen pictures of it. And while our bungalow is on one side of the mountain torrent there is another one, not far off, on the other side, where the boys are going to stay."

"How nice," commented Bess.

"Is that other bungalow within sight or calling distance of ours?" asked Belle.

"One or the other, yes," a.s.sented Cora. "But why so anxious?"

"Because when those ghosts, or whatever they are, get to moving things about I want a man, or at least a good-sized boy around," was the answer.

"Nonsense!" exclaimed Cora. "It isn't so bad as that."

"Say it again," begged Bess. "You told about unseen hands moving chairs and tables."

"I didn't mean it exactly that way," and Cora smiled. "You see there is a man and his wife who have rooms in the bungalow, Mr. and Mrs. Floyd.

They look after the place, and they'll be our chaperons. I did think mother might be able to go with us, but she won't. But mother knows Mrs.

Floyd, and says she's very nice."

"I hope the ghosts will be nice," said Belle.

Cora laughed.

"Oh, you funny girl! Why will you persist in calling them ghosts?"
