Nick watched them pass away, and the face of the fat boy told that his soul was troubled. Yet it was not so much of himself he thought, but the strange mystery hovering over this vanishing of Josh.

Jack knew where the long-legged would-be hunter had last been seen, and accordingly he made direct for that spot.

Evidently he had no especial trouble in discovering the tracks left by the heels of Josh’s shoes, for those left behind saw the trio move directly away. Soon the flitting glimmer of the moving lantern vanished entirely among the thickets covering the land in places.

Josh had headed down the shore when he went forth to try and add to the camp larder by knocking down a bunch of the tasty little snipe and other shore birds, flocks of which were seen whenever the tide changed, and the mud flats became partly bare.

That meant he had gone west, for the boys had fallen into the habit of saying “down” as long as they were headed south; and until they turned up the coast it would continue that way.

Jack led with his lantern, and carrying the rifle in his other hand. For some little time the three boys kept on this way. When the tracks became harder to see, Jack used his judgment, and managed to pick up the trail again every time.

All the while George and Jimmy were casting uneasy looks ahead. The moon being past its prime, would not rise for some time; and as a consequence all was pitch darkness around them. It was easy to imagine all sorts of perils lurking in that gloom beyond. Every simple little sound, such as a stray ’coon scampering away at the coming of the swinging light, caused them a new quiver.

George could not get that strange motor boat out of his mind. He believed that it had left Miami ahead of them, for it was gone on the morning after their arrival. And the chances were that it had come down here ahead of them.

Having more or less of a vivid imagination, George was picturing all sorts of strange things as happening. He even looked back along the career of their chum, Josh, trying to figure out some romantic reason for these people on the strange craft to want to kidnap the long-legged youth.

Despite his best efforts, however, this was pretty much a failure. There never was a fellow with more of an ordinary every-day past than the said Josh. George had known him since they were kids together, first starting in to school. His father was one of the substantial men of the town; and, so far as George knew, there had never been even the faintest rumor of anything singular attaching to the Purdue family.
