They were soon moving along, the two trackers in the van as before, with others trailing after. Landy brought up the rear, though Mark kept a careful eye on him most of the time, as though rather skeptical about his ability to make progress without getting into some sort of trouble.

It would be just like clumsy Landy to trip, and make a headlong plunge into the brown tamarack water of the swamp just when he should have been most careful. They had known him to do such things more than a few times in the past; and on this account Mark always made it a point to drop back and keep him company when he imagined the situation became acute.

From the rapid manner in which Lil Artha and Elmer picked up the trail it was plainly evident that so far the unknown fugitive from justice had not bothered resorting to any of his tricks looking to blinding the tracks.

He had been compelled to wait for daylight before trying to move through the swamp, because progress would have been next door to impossible at night time unless one were familiar with the way, or else carried a lantern. Neither of these happened to be within his scope, and so he had to depend upon daylight.

Of course, none of the boys knew what sort of a reception they might expect when finally they overtook the man they were following. What little they could gather from various sources inclined them to believe he must be a pretty desperate sort of customer. The occasional mention of him in that strange message left by Hen was along those very lines.

He might be armed for all they knew. Such criminals usually are, though in this case it might be otherwise, Elmer had told them, since he believed the man had been a prisoner making his escape when first he struck Sassafras Swamp, and concluded to have his hide-out in its depths.

Still Lil Artha was not for taking too many chances. As he moved along, the tall scout managed to keep that reliable gun of his in position for quick use, should an occasion arise calling for service.

He also tried to glance ahead from time to time, in hopes of locating any suspicious ambuscade. A sudden attack that would leave himself and Elmer weaponless might throw the entire party into a state of helplessness, which would always reflect on their ability as scouts.

They spent half an hour in this fashion, though the trail wound in and out so much that at the end of that time they could hardly have been more than a quarter of a mile away from the late camp of the fugitives.

"Did you hear that, Elmer?" whispered Lil Artha, suddenly, throwing out a hand so as to clutch the other's arm; while everyone became rigid with suspense.
