The island could now be plainly seen. It did not look so large by half as when they had seen it on going up the river; but the more elevated parts were standing well out of the flood. On the upper end was a mass of accumulated debris in the shape of stranded trees and logs.

Poor Sandy looked, and a groan burst from his lips, for he feared they would not be able to overcome the current sufficiently to bring their little craft close enough to that friendly shore to enable them to land!

And Bob, who clung so desperately to hope, knew that there was absolutely no chance for them to reach a landing spot at the upper end, even if they had wanted to mix up with all that mass of interlocked trees.

He had grasped the situation in a comprehensive way, and sized it up.

The island was narrow, but somewhat lengthy. Of course the current ran like a mill-race along the shore. But Bob knew that below, where the two opposite tides met once more, there was bound to be somewhat of a reaction. Here a little backward swirl would be found, a sort of undertow, bearing upstream toward the foot of the island.

It would only extend for a limited distance. Once they got beyond that drawback, and there was absolutely no hope of making land!

And that was the one thing he had in mind when he sang out so encouragingly to his weaker brother:

"It is our only chance!"

Sandy was paddling with all his nerve, but not making a very great success of the effort. In fact, he was so winded that he hardly knew when he dipped his blade in the yeasty water, or drew it quaveringly toward him.

Still, he was game, and would not give up so long as he could move a hand. What little he could do to help might not stand for much, but every bit helped, and even in his great distress Sandy realized this.
