"Oh, they took some bacon, coffee and other things with them," said
Aunt Millie. "They often have to camp out for days at a time."

"Say, I wish I could do that!" cried Teddy.

"Wait until you get to be a cowboy," advised his father.

That afternoon Trouble went to lie down with his mother to have a
nap, and Teddy and Janet wandered off by themselves, promising not to
go too far away from the house.

But the day was so pleasant, and it was so nice to walk over the
soft grass that, before they knew it, Teddy and Janet had wandered
farther than they meant to. As the land was rolling--here hills and
there hollows--they were soon out of sight of the ranch buildings,
but they were not afraid, as they knew by going to a high part of the
prairie they could see their way back home--or they thought they
could. There were no woods around them, though there were trees and a
little stream of water farther off.

Suddenly, as the Curlytops were walking along together, they came to
a place where there were a lot of rocks piled up in a sort of
shelter. Indeed one place looked as though it might be a cave. And as
Teddy and Janet were looking at this they heard a strange noise,
which came from among the rocks.

Both children stopped and stood perfectly still for a moment.

"Did you hear that?" asked Jan, clasping her brother's arm.
