Dot's reply, however, was reassuring.
"No, Mrs. Carter, I must stick with Linda. It isn't often that my mother gives in and lets me go off like this, and I mean to take advantage of it Besides, there's adventure ahead!"
Mrs. Carter sighed; these modern girls were beyond her comprehension. She was thankful that her only child was a boy.
While Dot was saying good-by, explaining that the Mackays had to be up early in the morning, Jackson managed a whisper to Linda.
"When can I see you, Ann? I just must!"
Linda smiled; she was in command of herself again. She had won in a difficult situation.
"Some time when we both winter at Palm Beach or Miami," she replied, lightly, as she nodded good-by to his mother.
The young man's interest in Linda had not escaped Dot's notice. When they had left the restaurant, she remarked, teasingly:
"You certainly made a hit, my dear. But I'm just as glad you turned down their invitation. The Carters have a marvelous home, I believe, but they're about 1890 vintage. They don't know that there was a War."
"Well, we really haven't any time to lose," was her companion's reply. "I'm almost afraid now that Susie will be gone when we get to that island. And I'm in a hurry to help the police trace that other thief with the money."
"Adventure is right!" laughed Dot, as the girls said good-by to Ted and Louise, and went to their room.
The Mackays left soon after dawn the following morning, but Linda and Dot had decided to have a good sleep. They did not waken until after ten o'clock, when they heard the telephone ringing in their ears.
It was Dot who answered it.
"Oh, hello, Jackson!" she said, with a wink at Linda. "I used to call you by your first name, so I suppose I might as well now. How's everything?"
"Just fine," replied the young man. "And Dot – may I speak to Miss Carlton?"
"O.K.," answered the girl, holding the telephone towards Linda.
"Not awake yet!" yawned Linda, burying her head in the pillow.
"She says she's not awake yet," explained Dot, laughingly. "Better call later, Jackson – after we get some breakfast."
Replacing the telephone, she turned to her roommate.
"That big boy certainly fell for you, Linda!" she exclaimed, still unaware of the fact that Jackson had not met her for just the first time.
"Well, I didn't fall for him," the other stated, firmly. "And Dot, please, from now on I'm not at home when he calls."
Dot was surprised at this announcement; it was unlike Linda not to be friendly to everybody. Why had she taken such a dislike to a young man as handsome as Jackson Carter?
"May I ask you a personal question, Linda?" she inquired.
"Why certainly, Dot!"
"Are you engaged to Ralph Clavering – and is that why you're turning other men away?"
Linda laughed at the idea.
"No, Dot – I'm not engaged to anybody. And I don't want to be. I want to be free for a while. But not from my girl-friends!" she added hastily, reaching over and giving Dot a hug. "Oh, Dot, if I could ever tell you what it meant to me to have you three breeze in last night! Honestly, I was awfully low."
"It was Lou's idea," explained Dot. "I guess she thought you would be – so far away from everybody – even if you hadn't been in any difficulty."
"Lou's a peach," observed Linda.
They ordered a tray sent up to their room, and lingered lazily over their breakfast. Before they had finished the telephone rang again. This time it was the Jacksonville Airport, informing Linda that the new parts for her autogiro had arrived.
"I'll have to hurry!" she said to Dot. "I don't want to lose a minute now."
"Just what are your plans, Linda?" asked the other girl, as she, too, started to dress.
"Go to the airport and have the parts for the Ladybug put into a plane. Then fly to Soldiers' Camp Island, taking another mechanic along. I'll help this man fix the autogiro – collect Susie – and fly back here."
"You really believe you can fix it in one day?"
"Yes, of course. Why not!"
"Well," said Dot slowly, "I think if you don't mind, I'll stay here. You'll need all the space you can get in your plane to carry those parts to the wreck. And I'd be fearfully bored standing around while you work."
"I guess you're right," agreed Linda. "It would be better for me to take two men – a pilot and a mechanic. Because I can't fly this hired plane back again – I'll have to pilot the Ladybug."
"And you have to bring Susie too," Dot reminded her.
Linda lost no time in getting ready, and she was pleased to have left the hotel before Jackson Carter had a chance to telephone again. She found a "repair" plane waiting for her at the airport, and she made note of the new parts for the autogiro that were already packed into it. Two men were prepared to go with her – one a pilot, the other a mechanic. For once in her life Linda was to ride as a passenger.
The day was hot and dry, but over the swamp the air seemed cooler and fresher. The rainy season was late, everybody said; by this time of year the swamp was usually flooded.
As the plane flew over the desolate expanse, Linda smiled to herself at the familiarity of the landscape. She was getting to be an authority on the Okefenokee Swamp; she never need fear again being lost in its southern part, at least. Although the pilot had a reliable map, he found Linda's directions helpful, and before noon they came down on Soldiers' Camp Island.
The first thing that struck their notice was the autogiro, still leaning over on its side, looking pathetically helpless in its plight. But Susie was not in sight.
While the men unloaded their tools and the new parts for the damaged plane, Linda went in search of the girl she had left there two days before. It was queer, she thought, that Susie had not come out to meet them at the sound of their motor. Was it possible that she was sick – or only asleep?
The island was a comparatively large one, several miles in length, and Linda decided immediately to explore it. Susie might be waiting somewhere within its depths, helpless or hurt, if she had fallen on her injured ankle. It would be necessary to make a thorough search.
Linda ran back to the autogiro to inquire whether the men needed her help, and explained what she was about to do.
"We don't need you yet, Miss," replied the mechanic. "Later on, when she's almost finished, you can help me look her over, and take her up for a test."
"By the way, Miss Carlton," put in the pilot, "did you think to bring any food for lunch? I only brought water."
Linda shook her head regretfully. How could she have been so stupid? Had her excitement over regaining her autogiro destroyed all her common sense?
"I'm awfully sorry," she said. "I just plain forgot! And I usually have some in the autogiro, but those thieves took it out… Wait, though! There may be some on the island. We left a half a dozen cans with this girl."
A search of the little "houses" farther in on the island revealed what she had been hoping for – the remainder of the supplies the boys had left with Susie, consisting of two cans of baked beans, tea, coffee, sugar and canned milk. This ought to be enough for their lunch, and she ran back immediately to the men with the good news.
