So we brought our raft to anchor at about the place from which he had started out and pitched camp on a stretch of clean yellow sand. I shall never forget that night. It was uncanny. None of us slept well. All through the hours of darkness we heard things moving around us. Enormous things. Yet never did we see them or find out what they were. The four of us were nevertheless certain we were being watched. Even Polynesia was disturbed. There seemed no doubt that there was plenty of animal life in the Moon, but it did not as yet want to show itself to us. The newness of our surroundings alone was disturbing enough, without this very uncomfortable feeling that something had made the moon folks distrustful of us. THE SEVENTH CHAPTER Tracks of a Giant Another thing which added to our sleeplessness that night was the continuance of the mysterious music. But then so many strange things contributed to our general mystification and vague feeling of anxiety that it is hard to remember and distinguish them all. The next morning after breakfasting on what remained of our fruits we packed up and started off for further exploration. While the last of the packing had been in progress Chee-Chee and Polynesia had gone ahead to do a little advanced scouting for us. They formed an admirable team for such work. Polynesia would fly above the forest and get long-distance impressions from the air of what lay ahead while Chee-Chee would examine the more lowly levels of the route to be followed, from the trees and the ground. The Doctor and I were just helping one another on with our packs when Chee-Chee came rushing back to us in great excitement. His teeth were chattering so he could hardly speak. “What do you think, Doctor!” he stammered. “We’ve found tracks back there. Tracks of a man! But so enormous! You’ve no idea. Come quick and I’ll show you.” The Doctor looked up sharply at the scared and excited monkey, pausing a moment as though about to question him. Then he seemed to change his mind and turned once more to the business of taking up the baggage. With loads hoisted we gave a last glance around the camping ground to see if anything had been forgotten or left. [Illustration: “_‘What do you think, Doctor?’ he stammered_”] Our route did not lie directly across the lake, which mostly sprawled away to the right of our line of march. But we had to make our way partly around the lower end of it. Wondering what new chapter lay ahead of us, we fell in behind Chee-Chee and in silence started off along the shore.
