Of course Ted could not tell who had made them, but he thought surely it must have been the tramp who had pulled Trouble from the spring. Ted was sure they were not the footprints of himself and his sister, for their own were much smaller.
"Come on, Jan!" cried Teddy. "We'll find that tramp now or, anyway, the place where he hides."
He pushed on through the bushes. There seemed to be a sort of path leading away from the spring, which was not the same path that Ted and Grandpa Martin took when they went from the camp to the water-hole to fill the pail each day. On and on went Ted, with Jan following. She was so excited now at the thought that perhaps they might find something, that she was not a bit frightened.
"Wait a minute! Wait for me, Teddy!" she called, as her brother hurried on ahead of her.
"Come on, Jan!" he called. "There's a good path here, and I guess I see something. Oh, look here! Oh, Jan! Oh! Oh!" suddenly cried Teddy. Then his voice seemed to fade away, as if he had all at once gone down the cellar, and Jan could hear him calling faintly.
"Oh, Teddy! What's the matter? What's the matter?" she cried as she ran on through the bushes.
"I've found the cave!" was his answer, so faint and far away that Jan could hardly hear. "I've found the cave. I fell right into it! Come on!"

Wondering what had happened to her brother, Jan hurried on toward the place from which his voice came. It sounded more than ever as if he were down a cellar.
