absolutely nothing wrong with it," snapped Mollie at last, lifting a face flushed with exertion. "Get in, girls, and I'll start the engine! or try to. Then if she won't go we'll have to make up our minds to stay here all night or walk to the next garage."

Accordingly the girls got in and Mollie pressed the self-starter. To her great surprise, the engine purred a response, and as she shifted her gears the car moved slowly forward.

"Oh, goodie, we're going," cried Amy, and the faces of the other girls showed relief.

"Must have been a drop of water in the gasoline," hazarded Mollie, and then she throttled the engine once more while she and her chums turned to say good-bye to Professor Dempsey. The latter was still standing in the road, looking up at them rather wistfully.

"I'm glad that I had an opportunity of helping you, young ladies! very glad," he answered, in response to their repeated thanks. "You conferred a great favor on me also, for I have little company. Good-bye! and good luck to you."

The girls responded gayly, and as they started forward Betty leaned far out of the machine to call back an encouraging: "Keep hoping hard for your boys to come home. I am sure they will be back soon."

"Thank you, young lady, thank you," said Professor Dempsey, but the words were too low for Betty to catch and she was too far away to see the mist that sprang suddenly to his eyes.

CHAPTER IV

GOOD NEWS

Deepdale, the home of the four Outdoor Girls, is a thriving little city with a population of about fifteen thousand people. It is situated on the Argono River, a pleasant stream where a great many of the young folk of Deepdale, and some of the older ones too, keep motor boats and canoes and various other types of pleasure craft.

Farther on, the Argono empties into Rainbow Lake, which is picturesque in the extreme. It has several pretty and romantic looking islands, chief of which is Triangle Island! so called because of its shape.

There is a boat running from Deepdale to Clammerport at the foot of Rainbow Lake, and this boat is almost always crowded with pleasure seekers. In addition to this Deepdale is situated in the heart of New York state and is only a hundred-and-fifty-mile run from the city of that name. Thus one can easily see that Deepdale is a very desirable place in which to live.

At least that is what the four Outdoor Girls thought. And since they had spent most of their lives there, they certainly ought to know!

On the morning of this day, some ten days or so after their strange encounter with Professor Dempsey, the girls were gathered on Betty's porch, talking over their plans for the summer.

"I am only waiting to hear from Uncle John," Mollie was saying, as she swung lazily back and forth in the couch swing. "The last time I saw him he said that he was almost sure to go north this summer and he told me that as soon as he made definite plans he would let me know."

"You told us that two weeks ago," Grace reminded her. "And we haven't heard from him yet."

"It does seem to take him a long time to make up his mind," sighed Amy.

Betty, who had been trying to read a novel, closed the book and turned to them with a laugh.

"Goodness, you all sound doleful," she told them. "It seems to me that we ought to be able to live through it, even if we don't get Wild Rose Lodge for the summer. There are plenty of other things we can do,"

Mollie turned upon her indignantly.

"How you talk, Betty Nelson," she scolded her. "As if we could possibly have as good a time anywhere else as we could at Wild Rose Lodge. Think of being in a real hunting lodge out in the woods away from everybody! Why, it will be a real adventure!"

"All right. I surrender! don't shoot," laughed Betty, coming over and perching on the railing beside Mollie. "I admit we should probably have more fun at the lodge than we could anywhere else. I was only trying to look on the bright side of things in case our plans should fall through. Hello! who's this?"

"This" proved to be Mollie's little sister Dora, or "Dodo," as she was called by almost everybody. With a sigh of relief, the girls saw that Dodo's twin brother, Paul, was not with her, for together the children were a simply unconquerable pair.

The twins had been spoiled by their widowed mother, Mrs. Billette, even before the time when they had been kidnapped and spirited off by a hideous Spaniard. But since their recovery, their joyful mother had indulged them in every way until they had become well nigh unmanageable.

Yet in spite of everything, the twins were very lovable, and every one loved them, even those whom they annoyed most.

And now as Dodo tore up the street toward them, waving something white in her hand, the girls instinctively glanced about to see what they ought to put out of sight before the cyclone struck them.

"Thank goodness, Paul isn't with her," murmured Grace. "Then we would be in for it."

"Dodo," cried Mollie as the child started up the walk, "scrape some of that mud off your feet before you come up, You will get Betty's porch all dirty."

"Name's Dora! not Dodo," the little girl answered, paying not the slightest heed to Mollie's caution about the mud. "Dodo's a baby's name! don't like it. Got something for you."

She stumbled heedlessly up the steps, leaving a trail of mud behind her, and almost breaking her neck in the bargain.

"Now just look at Betty's porch," Mollie was beginning in exasperation when Betty laughingly interfered.

"Oh, let her alone, Mollie," she coaxed. "The porch was dirty anyway and! what's that you have in your hand, Dodo?"

"Sumfin' for Mollie," answered Dodo, leaning sulkily against the rail while the girls regarded her anxiously. "An' if Mollie aren't nice to me she can't have it."

"Oh, for goodness' sake be nice to her and get it over with, Mollie," urged Grace, uneasily conscious of the candy box she had shoved hastily behind her. She was afraid one corner of it might show.

So Mollie got down from her perch on the railing and went over coaxingly to the little girl.

"Give it to Mollie, honey," she begged. "I'll even call you Dora, if you will."

"Always Dora! never Dodo?" asked Dodo eagerly, for she was growing out of babyhood just enough to resent being called by her baby name.

"Always Dora," Mollie promised.

For answer Dodo held out the white thing she had waved at them from the street, and with a little cry of excitement Mollie saw that it was a letter addressed to her in her Uncle John's firm hand.

At her exclamation the girls crowded round her eagerly. She hastily tore open the envelope and devoured the contents. Then she turned to the girls with a glowing face.

"It's all right, it's all right!" she cried, waving the letter round her head like a flag and nearly upsetting her chums. "Uncle John says it is settled. He is going to Canada for a couple of months and we can have the lodge for the whole time he is away or a part of it, just as we wish. Hooray! How's that for luck?"

The girls were so excited over their good fortune that they forgot all about Dodo. She, finding herself unobserved, had slipped around the girls to the swing, snatched the box of candy which Grace had exposed when she got up, had taken the steps two at a time and was flying off down the street before the girls saw what she was up to.

Then it was Grace who, with a dreadful premonition, thought of her candy. She turned quickly, saw that the box was gone, and uttered a wail of woe.

"That little Turk of a sister of yours has done it again," she cried, turning to Mollie, while Betty and Amy began to laugh. "You just wait till I catch her. I'll get my candy back if I have to! spank her," this last with a fierce scowl.

Betty put an arm about her excited chum, led her over to the swing and put her down in it.

"By the time you caught Dodo there wouldn't be any of
