“It must be a chart of the river!” George took occasion to faintly whisper in Jack’s ear, taking advantage of the murmur of the night wind among the branches of the trees overhead.
Of course this did not enlighten Jack any, since he had jumped at the same conclusion long before. But the fact of the others studying a map of the river’s crooked course was highly significant, he thought. It told that they realized the danger they stood in of being overtaken, and that they meant to lay out a plan whereby they could elude pursuit.
Jack was studying the pair as he lay there back of the bushes.
He wondered whether the younger one, who seemed to be at the head of the dangerous combination, could be acting a part. This idea came to Jack because, as far as he was able to see, the other looked as though he hardly possessed brains enough to carry him through any ordinary trouble; and as to plotting such a bold thing as looting a country bank, why, Jack found it hard to believe he would be capable of it. But still, he knew very well that it is not always safe to judge from first appearances. While the skipper of the white power-boat might seem to be a bit of a “sissy,” that might all be assumed for a purpose, to allay suspicion, a part he liked to play; and that should occasion ever call for a display of force and ugliness, the fellow might throw off that careless demeanor as one would an old glove, appearing in his real colors.
And while lying there, watching, and trying to pick up a sentence now and then, as the pair chanced to speak in a little louder tones, Jack busied himself in speculating what sort of chances they would have, did they finally decide to accept of the opportunity to close in on the two rascals, and bring about their arrest.
It would be taking a certain risk of course, and he did not want to expose his chums to any unnecessary chances for getting hurt; but all the same temptation loomed up large before Jack’s eyes.
At any rate, he thought, it would do no harm to try and keep a watchful eye on the pair, and see what they were up to. Had he not in the beginning heard the leader say that they might as well bury the treasure on the island as carry it further with them. Of course they meant to come back again, and get possession of whatever that small box contained.
The thought of getting hold of the stolen bank funds and papers gave Jack a nice warm little thrill. He was only a boy, and yet he knew how splendid it was to return home, and hear the people cheering him, while the town band played “Lo, the Conquering Hero Comes.” And once before had they been instrumental in recovering plunder that had been taken by wandering yeggmen; which fact had helped swell the contents of the club’s strong-box, and enabled the members to take several long and expensive trips.
