He bent over and looked closely at the sandy shore. It was all too evident that some sort of a struggle had taken place there, and that recently. The marks visible by day but not at night proved this.
“Those marks weren’t there when we landed yesterday afternoon,” decided our hero. “Besides, they’re quite a distance from where we brought the skiff in. There’s been some sort of a boat here,” he went on, as he bent over the impression made by the sharp prow of some craft in the sand. “Someone came in a boat, got hold of the boys somehow, and carried them off. But there was a fight all right, and a good one, too, I’ll wager.”
It did not take a mind-reader to decide this. The sand in several places was scuffed about, raised up in ridges, or scratched into depressions, while the heel marks, deeply indented in the soft material, showed how desperate had been the struggle. But the chums had been overpowered, that was certain, for they had been taken away.
“And in my boat, too, I’ll wager!” cried Tom. “The impudent scallawags! To take my boat, and then use it to carry off my friends. They must have taken some of my gasolene, too. Oh, wait until I get a chance at them!”
The new discovery was overpowering for a time, and Tom sat down to think it out. Then he came to a decision.
“I’ve got to help my chums,” he said. “I’ve got to go to their rescue. There’s but one place where they would be taken. The old hermit, or Skeel and the cronies, have them in the old mill—or, hold on—maybe they’re captive in the cave where we stayed that night. Those are two places where they might be. What shall I do?”
It was no easy problem for the lone camper to solve, and Tom was frankly puzzled.
“I think I’ll tackle the old mill first,” he decided. “That’s the most likely place. Though I wonder why in the world the hermit or Skeel would want to capture Dick, Bert and Jack? Unless the treasure has been located, and they don’t want us to find out about it. But they haven’t got me!”
With Tom, to decide was to act, and so, putting himself up a lunch, he set off in the skiff for the old mill. It was hard rowing alone, for usually two worked at the oars, but our hero stuck to it, and in due time he reached the river. Then he decided to pay a visit to the cave.
He concealed his boat under some bushes, and, taking the oars with him, he hid them well up on the hill.
