It was no great task to follow the marks made by the crawling man. His toes had dug into the soil, going and coming, for apparently he had used the same trail both ways.
"Here we are, boys; now, take a look!" said Paul, presently.
They were by this time in the midst of the timber with which this end of the island was covered. Glimpses of the tents could be seen between the trees; but any intruder might feel himself reasonably justified in rising to his full height when he had made a point so well screened from inquisitive eyes.
This man had done so, at any rate. The plain print of his shoes was visible in a number of places. Both Jack and Bobolink gave utterance to exclamations as soon as they saw these.
"One of the four, that's dead sure!" the former declared, positively.
"I'll be badgered if it ain't!" muttered Bobolink, staring at the tracks.
"So you see, we've settled one thing right at the start," said Paul.
"That's what we have," observed Bobolink. "It's those fellows who carried the heavy load from the rowboat, after landin' on the island, after the rain storm, that want our room more'n our company. The nerve of that bunch to tell us to clear out, when chances are we've got just as much right here as they have—p'raps a heap sight more."
"That doesn't sound much like you wanted to make a change of base,
Bobolink?" remarked Paul, smiling.
"No more do I," quickly replied the other. "I'm not used to bein' ordered around as if I was a slave. What if there are four of them, aren't eighteen husky scouts equal to such a crowd? No, siree, if you left it to me, I'd say stick it out till the last horn blows. Give 'em the defi right from the shoulder. Tell 'em to go hang, for all we care. We c'n take care of ourselves, mebbe; and mind our own business in the bargain."
