"That distant roaring?"

"Yes; it has become a roar now. What do you suppose it can be?"

"It must be the falls that Skor told me of," said Nalte.

"By Jove! That's just what it is," I exclaimed. "And the best thing that we can do is to get to shore while we can."

The current had carried us closer to the right bank at this point, and just ahead of us I saw a small stream emptying into the river. There was an open forest on the farther side of the stream and scattered trees on the nearer.

It appeared an ideal location for a camp.

We made the shore easily, for the current here was not swift. I ran the boat into the mouth of the small stream, but there was not water enough to float it. However, I managed to drag it up far enough to tie it to an overhanging limb of a tree where it was out of sight of any possible pursuers from Kormor who might come down the river in search of Nalte and myself.

"Now," I said, "the thing that interests me most at present is securing food."

"That is something that always interests me," admitted Nalte, with a laugh. "Where are you going to hunt? That forest on the other side of this little stream looks as though it should be filled with game."

She was facing the forest as she spoke, while my back was toward it. Suddenly the expression on her face changed, and she seized my arm with a little cry of alarm. "Look, Carson! What is that?"
