e marks of shoes in the dirt.

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!"

CHAPTER X

THE GRAPEVINE SWING

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.

"But there can't be any cellars in these woods," thought the little
girl.

"Where are you, Teddy?" she called after a bit. "I can't see you!"

"Here I am, right behind you!" was the answer, and Jan, turning quickly,
saw the head of her brother sticking up out of a hole in the ground.

"Oh! Oh!" exclaimed Ted's sister. "Where's the rest of you? Where's your
legs and your feet?"

"Down in the hole," explained Teddy. "I'm in the cave. I fell in. That's
how I found it."

"Is it a real cave?" asked Janet.

"It is. It goes away back under the ground, only I didn't go in 'cause
it's so dark. I'm going to get a light and see what's there."

"I'm not!" said Jan, very decidedly.

"Well, then I'll get grandpa. Maybe this is the cave where the tramps
live. Come and look where I am. You won't fall in."

"How did you find it?" asked Janet, as she walked toward the hole, down
in which Tedd
