Following Nalte's suggestion we drifted slowly down stream. We soon passed Kormor, but the white city on the right bank extended on for a couple of miles farther. I should say that its full length along the river front was fully five miles, and along all that length was the broad quay backed by a gleaming white wall pierced by an occasional gate--I counted six or seven along the full length of the water front. Just below the city the river turned to the right, and almost immediately the cliffs shut off our view of both cities. Simultaneously the aspect of the country changed. The limestone cliffs ended abruptly, the river running between low banks. Here it spread out to considerable width, but farther ahead I could see where it narrowed again and entered a gorge between cliffs much higher than any that we had passed. They were wooded cliffs, and even from a distance I could see that they were not of the white limestone that formed those with which we had now become familiar. There came to my ears faintly an insistent sound that was at first little more than a murmur, but as we drifted down the river it seemed to grow constantly in volume. "Do you hear what I hear?" I demanded, "or am I the victim of head noises?" "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?" XIII TO LIVE OR DIE As I turned at Nalte's warning cry, I thought that I saw something dodge behind low bushes on the opposite bank. "What was it, Nalte?" I demanded. "Oh, it couldn't be what I thought I saw," she whispered excitedly. "I must be mistaken." "What did you think you saw?"
