As usual, Sandy sat in the bow of the boat, while his brother managed the stern paddle with considerable dexterity. Until they had come to the Ohio country neither boy had had very much experience in boats; but, after the dugout was built, they spent much of their time on the water, shooting ducks for the family larder, fishing, or crossing over to hunt on the other shore, where, later on in the fall, they had stretched a line of traps that brought them in many a fine pelt. They soon found that, somehow, owing to the trend of the shore, perhaps, it was going to prove an even more difficult task to push the heavy dugout back to the southern side of the river, than it had been in coming across. The current added to their troubles, for it carried them along faster than either of the boys had dreamed possible. For the first time, possibly, they were learning of the power of the flood, once it arose in its tremendous might. Both lads strained every muscle as they drove the blades deeply into the water. They had, by the hardest kind of work, managed to get about half-way over, though both of them were somewhat winded by their efforts, when they noticed that heavy clouds, rolling up across the heavens, had begun to bring the dusk of night much earlier than even the careful Bob had anticipated. There were many obstructions that had to be avoided. Trees were floating on the surface of the water in places, and logs seemed plentiful. Altogether, it was an entirely new sight to both Bob and his brother, for, until now, they had never known the beautiful Ohio to rise to a point that could be called dangerous. "Take care, and keep away from that tree!" warned Bob, as he saw a particularly ugly snag, with broken branches sticking out along its sides, bearing down upon them on the left. They had to paddle furiously in order to keep clear of this threatening object, and, possibly, in his eagerness, Sandy may have bent too heavily on his paddle, for, just as they reached a point where they would be safe from the floating tree, there was a sharp snap. "What happened?" cried Bob, alarmed more than he would have liked to confess. For reply Sandy held up the stump of his paddle. It had broken off clean, and, from that time on, only one could paddle at a time. This catastrophe was sure to delay their passage, and doubtless cause them to be swept some miles down-stream before they could land; but the boys were hardy, and would not mind walking back, though doubtless Sandy might complain a little on account of his lame leg. Bob set to work again with a good will, and was making fair progress when yet another peril came booming along, this time in the shape of a heavy log that was sweeping with the speeding current.
