Besides, it paid, for any one could see that they were steadily getting in deeper and deeper. The swamp was becoming much wilder now; and it was not hard to realize that a man getting lost here, and losing his head, might, after his bearings were gone, go wandering at haphazard for days, possibly crossing his own trail more than a few times.

It seemed a lonesome place. Animals they saw none. Perhaps there might be deer in the outer portions, but they never came in here. Although the scouts saw no evidences that wild-cats lived in the swamp, they could easily picture some such fierce animal crouching in this clump of matted trees or back of that heavy bush, watching their passage with fiery eyes.

The scouts found their long staves of considerable use from time to time. Had Noodles for instance been more adept in the use of the one he carried he might have been saved from a whole lot of trouble. Perhaps this might prove to be a valuable lesson to the boy. He could not help but see how smartly the others kept themselves from slipping off the narrow ridge of ground by planting their staves against some convenient stump, or the butt of a tree, anywhere but in the oozy mud.

"Wait up for me!" Noodles would call out every little while, when he fell behind, for he seemed to have a horror lest he might slip into that horrible bed of mud, and be sucked down before his chums could reach him. "It iss nodt fair to leave me so far behindt der rest. How wouldt you feel if you rescued der argonaut, and lose your chump; dell me dot? Give eferypody a chance, and—mine gootness, I mighty near proke my pack dot time," for he had come down with a tremendous thump, when his feet slipped out from under him.

But as a rule boys are not apt to give a clumsy comrade much sympathy, and hence only rude laughter greeted this fresh mishap on the part of Noodles.

"Nature looked out for you when she saw what an awkward chap you were going to be, Noodles," called back Fritz. "You're safely padded all right, and don't need to feel worried when you sit down, sudden-like. If it was me, now, there might be some talking, because I'm built more on the jack-knife plan."

"Oh! what is that?" cried Eben, as a strange, blood-curdling sound came from a point ahead of them; just as though some unlucky fellow was being sucked down in the embrace of that slimy mud, and was giving his last shriek for help.

As the other scouts had of course heard the same thing, all of the detachment came to a sudden halt, and looking rather apprehensively at one another, they waited to learn if the weird gurgling sound would be repeated, but all was deathly still.
