The boy's head rested on a thwart, and he faced the after-end of the skiff. As he was about to rise, his glance fell on something wrapped in newspaper and tucked under the stern seat. If it should only prove to be food of any description, "even burned mush," thought Winn, grimly, how happy it would make him! In another second he was undoing, with eager fingers, the lunch of crackers and cheese that Sheriff Riley's wife had so thoughtfully thrust into her husband's hands as he left the house the morning before, and which he had as thoughtfully tucked under the stern seat of his skiff. He was probably thinking of it, and wishing he had it, at this very moment. As for Winn, he was eating it as fast as possible, and thinking that he had never tasted such good crackers or such a fine piece of cheese in his life. With each mouthful his spirits rose and his strength returned, until, when the last crumb had disappeared and been washed down with a double handful of sweet river-water, the boy's pluck and cheerfulness were fully restored.
Now what should he do? He did not know that he had passed Dubuque, though he feared that such might be the case. Thinking of it brought to mind the island with those upon whom he had so recently turned the tables, and left as prisoners within its limits. He even laughed aloud as he pictured them toiling, as he had toiled the evening before, to construct a raft on which to escape. "I wonder if they found any one in that log-hut," he thought, recalling its lighted window. "And, oh! if it should have been father! It might have been. He might have seen my signal-fire, found my message, and got as far as the hut. Now what will he do? Oh, how I wish I could get back! Why didn't I think of all this before leaving the island? That was a horrid sound in the woods, though. And that animal! I wonder what it could have been?"
By this time the current had carried the skiff close in to the drowned bottom-lands of the Illinois shore. They were covered with a heavy growth of timber, and Winn knew that in many places the wellnigh impassable swamps which this concealed extended back a mile or more from the channel. Otherwise he would have abandoned the skiff and made the attempt to swim ashore.
The Iowa bluffs rose invitingly on the opposite side of the river. On them he saw a few scattered settlements, but they were too far away, and he must wait until the current set him in that direction before thinking of making a landing. He saw an occasional ferry-boat making its slow way across the river, but it was always either too far above him or too far below him for his signals to be noticed, and so the hours dragged on until it was late afternoon, and Winn was again beginning to feel the pangs of hunger.
"I can't spend another night in this wretched boat!" he exclaimed aloud, when he saw that the sun was within an hour of its setting. "I'll swim the whole width of the river first!"
During the day he had passed a number of small islands, but had not cared to attempt a landing on them. He knew that he would be even worse off on an island than in the skiff, and so he had watched them glide by without giving them any particular thought. Suddenly it occurred to him that on any one of these islands he might pick up an oar, a paddle, or at least something that would answer in place of these, and from that instant they acquired a new interest.
The next one that he approached was only a tow-head, which is a sand-bar on which has sprung up a thick growth of slender cotton-woods, or other quick-shooting, water-loving trees.
"I might find what I want there as well as on a larger island," thought Winn, "and, at any rate, I'll make a try for it." So when the skiff had drifted as near the tow-head as it seemed likely to, and was rapidly sliding past it, the boy threw off his coat, kicked off his shoes, and, taking one end of the skiff's painter with him, plunged overboard and began to swim towards the desired point.
The distance was not more than a hundred feet, but the current swept him down so much more rapidly than he expected that he was barely able to catch one of the very last of the tow-head saplings and cling to it. While his own progress was thus checked, that of the skiff was not, and in a second the painter was jerked from his hand.
Exhausted as he was, Winn was on the point of letting go his hold on the sapling and making a desperate effort to overtake the rapidly receding skiff. Fortunately he had enough practical sense, though this is not generally credited to sixteen-year-old boys, to restrain him from such a rash act. So he crawled out on the sand beach, and sat there watching what he considered to be his only hope grow smaller and smaller until it finally disappeared. As it did so, the sun slowly sank behind the western bluffs; and though the boy did not look up from the wet sand on which he had flung himself, he knew instinctively that another night, with its darkness, its chill, and its nameless terrors, was upon him.
