By this time the flood had risen still higher and higher, and was now ankle deep on the plateau outside the cave opening, and there was not a moment to lose.

With an energy that was all his own, and a skill that surprised himself, Sam set about building the raft.

By means of ropes, the longer timbers were securely lashed side by side, and over these, like a deck, the lighter slabs taken from the cave were nailed.

When this clumsy and insecure structure was completed, Sam saw that the food, blankets, arms and ammunition were tied so that they could not be swept off by the wash of the waters.

It comforted him somewhat to know that all his companions could swim, though the stoutest swimmer could not last long in the mad torrent sweeping past.

Sam assigned each one a position, and gave him strict instructions as to what he must do under certain circumstances; and Maj seemingly well aware of what was up, crouched down in the center of the raft.

"Now," said Sam, as he stood up, pole in hand, at one end of the raft, "we must wait for the current to float us off, and trust in God."

With his feet well apart to balance himself, and the long pole ready in his strong hands, Sam stood pale but resolute.
