"And thirsty. But it isn't so hot here as it was in Jacksonville."
"No. And the island out in the ocean ought to be cooler yet. You may like it so well that you'll want to spend the summer there. Only it has no tents or cots, like this camp."
"Thank you, I'd rather not play Robinson Crusoe," replied Dot.
"Poor man!" sighed Linda. "If he'd only had an airplane, how simple it would have been for him."
They ate their lunch, and then, for the third time, Linda flew across the Okefenokee and over the coastal plain of Georgia—out to the barren island in the ocean where the treasure had been hidden. The desolate loneliness of the spot impressed her companion.
"You suggested this as a summer resort!" she remarked, when they had landed. "Why, I don't even see a fishing-boat!"
"That's just the trouble," replied Linda. "The first time I flew here—with Susie's husband—I looked about desperately for somebody to shout to for help. And there wasn't a soul! Nothing but ocean and sky.... Do you have your revolver handy, Dot?"
"Yes. Right here. But I don't know much about shooting."
"I'm sure we shan't have to. I just want to explore. But 'be prepared' is our motto."
