“Well, I feel hungry enough now to eat an alligator egg omelet,” said Bobby. “I think we’d better get started, and maybe we’ll run across one of those cute little nests Lee was telling us about.”

After eating the last of the fish they had caught the day before, the boys started out, intending to follow the river as nearly as possible. But they soon found that the ground kept getting softer at every step they took, and were forced to bear away from the stream, although still keeping as near as possible to the right direction. Lee was more experienced than the other boys in the matter of making progress over this kind of treacherous footing, and he took the lead. On every side dark pools of water oozed up through the quaking ground. Here and there tussocks of grass had formed, and these offered the only footing to be had at all. Even these were very soft and shaky, and it was necessary to leap continually from one to the other in order to avoid sinking in. At rare intervals some larger hillock then, usual would give the boys a chance to rest a few minutes and get their breath, and it was on one of these that they paused at last, panting and tired.

“Gee!” exclaimed Bobby, as he mopped at his streaming face. “A mile of this is worse than ten miles on hard ground.”

“Harder, and a lot more dangerous,” agreed Lee, soberly. “One fall into one of those green pools and you’d be done for. It would suck you down so fast that nothing could save you.”

The heat was growing intense, and, aided by the rank steam that ascended from the rotting vegetation, seemed almost unbearable. But the boys knew that they had to keep on, because if darkness found them before they reached some firmer ground, their fate would be sealed. After nightfall they would be almost certain to fall into one of the green and stagnant pools and be sucked down to a horrible death.

Even as the boys tried to rest and get their breath, they could feel their feet slowly sinking into the muddy grass, and as they lifted their feet pools of water formed in the depressions left by them.

“Guess it’s a case of ‘keep moving,’” said Fred, as one foot sank in to his ankles and he pulled it out with difficulty. “This swamp is the last place in the world I’d pick for a hike if I had my choice.”

“There’s no choice about this,” said Bobby, setting his lips grimly. “We’re here, and we’ve got to get out just as soon as we can. Let’s go!”

Somewhat rested by their brief halt, they started on again. Suddenly Lee, who was ahead, shouted a warning.

“We can’t get any farther this way!” he cried, as Bobby and Fred caught up with him, and he pointed ahead. The boys saw a large stagnant pond, covered with green scum, from which protruded the rotting trunks of trees. At intervals around the bank lay what appeared to be other logs, but even as they looked, one of these seeming logs stirred, and crawling slowly through the ooze, flopped into the water with a loud splash.
