"That's a horse whinnying!" cried Teddy.

"Or a pony," added Janet. "Yes, it did sound like that. Oh, Ted,
maybe it's a poor horse in there and he can't get out!" she went on.

Again came the whinny of a horse or a pony. There was no mistake
about it this time.

"Come on!" cried Teddy. "We've got to get him out, Janet. He's one
of Uncle Frank's cow ponies and he's hurt in that cave. We've got to
get him out!"

"But how can you?" Janet inquired. "It's an awful little cave, and I
don't believe a pony could get in there."

"A little pony could," said Teddy.

Janet looked at the cave. She remembered that she had seen some
quite small ponies, not only on Ring Rosy Ranch but elsewhere. The
cave would be large enough for one of them.

"I'm going in," said Teddy, as he stood at the mouth of the hole
among the piled-up rocks.

"He might kick you," warned Janet.

"If he's sick enough to groan that way he can't kick very hard,"
replied Teddy. "Anyhow, I'll keep out of the way of his feet. That's
all you've got to do, Uncle Frank says, when you go around a strange
horse. When he gets to know you he won't kick."
