"Av this ain't a clear case av luck, Oi dunno mesilf!"
"We'll get the man who lives there to guide us out of the Everglades!" shouted the professor, in a relieved tone.
Then Frank cast a gloom over their spirits by saying:
"This may be a hunter's cabin, inhabited only at certain seasons of the year. Ten to one, there's no one living in it now."
"You'd be pleased if there wasn't!" almost snarled Professor Scotch. "You're a boy without a heart!"
Frank laughed softly.
"We'll soon find out if there's any one at home," he said, as the canoe ran up to the bank, and he took care to get out first.
As soon as Frank was out, the professor made a scramble to follow him. He rose to his feet, despite Barney's warning cry, and, a moment later, the cranky craft flipped bottom upward, with the swiftness of a flash of lightning.
The professor and the Irish lad disappeared beneath the surface of the water.
Barney's head popped up in a moment, and he stood upon his feet, with the water to his waist, uttering some very vigorous words.
