"There's another--there--look!" she cried. And then I saw it. It stepped from behind the bole of a large tree and stood eyeing us, its fangs bared in a snarl. It was a man that went on four feet like a beast. Its hind legs were short, and it walked on its hind toes, the heels corresponding to the hocks of animals. Its hands were more human, and it walked flat on the palms of them in front. Its nose was flat, its mouth broad, and its heavy, undershot jaws were armed with powerful teeth. Its eyes were small and close set and extremely savage. Its skin was white and almost hairless except upon its head and jowls. Another one appeared suddenly beside it. "You don't know what they are?" I asked Nalte. "We have heard of them in Andoo, but no one ever believed that they existed. They are called zangans. If the stories I have heard are true they are terribly ferocious. They hunt in packs and devour men as well as beasts." Zangan means beast-man, and no better word could have been coined to describe the creature that faced us across that little stream in far Noobol. And now others came slinking into view from the shelter of bushes and from behind the boles of trees. "I think we had better hunt elsewhere," I said in a weak effort to be jocose. "Let's take to the boat again," suggested Nalte. We had already walked a little distance from the spot where I had moored our craft, and as we turned to retrace our steps I saw several of the zangans enter the water on the opposite side and approach the boat. They were much closer to it than we, and long before I could untie it and drag it into deeper water they could be upon us. "It is too late!" cried Nalte. "Let's fall back slowly to that little rise of ground behind us," I said. "Perhaps I can hold them off there." We retreated slowly, watching the zangans as they crossed the stream toward us. When they came out on shore they shook themselves as dogs do, and then they came slinking after us again. They reminded me of tigers--human tigers--and their gait was much that of a stalking tiger as they approached with flattened heads and snarling lips. They growled and snapped at one another, revealing a viciousness greater than that of beasts. Momentarily I expected a charge, and I knew that when it came Nalte's troubles and mine would be over forever. We wouldn't have even a fighting chance against that savage pack. There were about twenty of them, mostly males; but there were a couple of females and two or three half grown cubs. On the back of one of the females rode a baby, its arms tightly hugging the neck of its mother. Savage as they appeared, they followed us warily as though they were half afraid of us; but their long, easy strides were constantly cutting down the distance between us. * * * * *
