The five continued their flight all that day, seeing no enemies and hearing no further signal from them. But Henry knew intuitively that the warriors were still in pursuit. They would spread out in every direction, and some one among them would, in time, pick up the trail. After a while, they permitted their own gait to sink to an easy walk, but they did not veer from their northeastern course. Henry, all the time, was a keen observer of the country, and he noticed with pleasure the change that was occurring. They were coming to a low sunken land, cut by many streams, nearly all sluggish and muddy. The season had been rainy, and there was an odor of dampness over all things. Great thickets of reeds and cane began to appear, and now and then they trod into deep banks of moss. "Perhaps we'd better turn to the north and avoid it," said Paul. "This marsh region seems to be extensive." Henry shook his head. "We won't avoid it," he said. "On the contrary it's just what we want. I'm thinking that we're being watched over. You know the forest fire came in time to save us, then the falls appeared just when we needed 'em, and now this huge marsh, extending miles and miles in every direction, cuts across our path, not as an enemy, but as a friend." "That is, we are to hide in it?" "Where could we find a better refuge?" "Then you lead the way, Henry," said Shif'less Sol. "Ef you sink in it we'll pull you out, purvidin' you don't go in it over your neck." Henry went ahead, his wary eye examining the ground which had already grown alarmingly soft save for those trained for such marchings. But he was able to pick out the firm places, though the earth would quickly close over their footsteps, as they passed, and, now and then, they walked on the upthrust roots of trees, their moccasins giving them a securer hold. It was precarious and dangerous work, but they went deeper and deeper into the heart of the great swamp, through thickets of bushes, cane and reeds, the soil continually growing softer and the vegetation ranker and more gloomy. Often the canes and reeds were so dense that they had difficulty in seeing their leader, as he slipped on ahead. Sometimes snakes trailed a slimy length from their path, and, hardened foresters though they were, they shuddered. Occasionally an incautious foot sank to the knee and it was pulled out again with a choking sigh as the mud closed where it had been. Mosquitoes and many other buzzing and stinging insects assailed them, but they pressed on without hesitation.
