“But how does that account for the ghost?” Ida insisted. “Why should such men seek to scare the wits out of a party like ours?”

“In the hope that we’d flee from this accursed spot as soon as daylight came,” responded Tremaine, with the positiveness of conviction.

“But what good, my dear, would it do to have a party like ours run away?” inquired Mrs. Tremaine, wonderingly.

“Why, we came here rather well supplied with fine provisions, didn’t we?” demanded Tremaine. “Now, if we were to run away without waiting for wagons, the gang behind the ghostly disturbances would find a goodly store of food in this house, wouldn’t they? And just the kind of food that these hungry wretches of the Everglades would prize highly. Also, if we fled in haste, we would have to leave much of our wardrobe behind. These fellows who rarely get to civilized communities must find some way of supplying themselves with clothing. Then, besides, if we ran away, we might even forget to take with us such valuables as we may happen to have here with us. So, all in all, a gang of desperate characters from the Everglades would find this house rather rich picking if we went away in haste as a result of a big fright.”

“I’m sure you’ve guessed the motives behind the ghost scares,” nodded Ida Silsbee. “And I can even understand why such men would find it worth while to steal the launch and run it into the Everglades. Yet why should they take that splendid young fellow, Tom Halstead, with them?”

“Unless to make him run the launch,” suggested Mrs. Tremaine.

Joe Dawson flushed, shaking his head.

“Tom couldn’t be made to help the scoundrels,” he declared, vigorously. “He’d die sooner than be driven into helping such villains!”

“Of course,” mused Henry Tremaine, “it’s more than barely possible that the wretches figured I’d pay a ransom to have Halstead set at liberty again.”

“Den’ ’scuse me, sah, but yo’ don’t believe it’s a real graveyahd ghos’ dat ha’nts dis country, and dat can trabble even out to sea on a gale?”
