The children saw many more of the little animals as they rode over the prairies.

"But we must look for marks--tracks, Baldy calls them," said Teddy.

"Tracks will tell us which way the Indians went," and so the children kept their eyes turned toward the sod as they rode along.

For a while they could see many marks in the soft ground--the marks of horses' feet, some shod with iron shoes and others bare, for on the prairie gra.s.s there is not the same need of iron shoes on the hoofs of horses as in the city, with its hard, paved streets. Then the marks were not so plain; and pretty soon, about a mile from the spring amid the rocks where the ground was quite hard, Teddy and Janet could see no marks at all.

"Which way do we go?" asked Ted's sister, as he called to his pony to stop. "Do you know the way?"

"No, I don't guess I do," he answered. "But anyhow we can ride along and maybe we'll see 'em."

"Yes, we can do that," Janet said.

It was still early in the afternoon, and the sun was shining brightly.

They knew they were still on Uncle Frank's ranch, and, though they could not see the buildings any more, they could see the place where they had had a drink at the spring.

"All we've got to do, if we want to come back," observed Teddy, "is ride to the rocks and then we know the way home from there."

"Yes, that's easy," Janet said.

So they rode on and on.

Of course the Curlytops ought not to have done what they did, but they did not think, any more than Trouble thought when he opened the corral gate and let out the ponies.

But the sun did not stay high in the sky all the afternoon. Presently the bright ball of fire began to go down in the west, and the shadows of Teddy and Janet grew long on the prairie. They knew what those long shadows meant--that it was getting late afternoon.

After a while Janet turned in her saddle and looked back.

"Oh, Teddy!" she cried. "I can't see the spring rocks," for that is what the children had called the place where they had found Clipclap.

"They're back there just the same."

"I know. But if we can't see 'em we won't know how to ride back to them," went on Janet. "How are we going to find our way back home, Ted?"

"Oh, I can get to the rocks when I want to," he said. "Come on, we'll ride a little bit farther and then, if we can't find daddy and Uncle Frank, we'll go back."

"Well, don't go much farther," said Janet, and Teddy said he would not.

There were many hills and hollows now, much higher and deeper ones than those near the ranch buildings. Even from the top of one of the high hills up which the ponies slowly climbed, the Curlytops could not see the spring rocks.

"Oh, Ted!" exclaimed Jan, "I'm afraid! I want to go back! It's going to be night pretty soon!"

"It won't be night for a good while," he said, "but I guess maybe we'd better go back. I can't see daddy, Uncle Frank or the cowboys."

He raised himself in the stirrups and looked across the prairies, shading his eyes with his hand the way he had seen some of the cowboys do. Nothing was in sight.

"Come on, Jan, we'll go back," he said.

Clipclap and Star Face were turned around. Once more off trotted the little ponies with the Curlytops on their backs.

The shadows grew longer. It was not so bright and nice on the prairies now. Janet kept close to Teddy. At last she asked:

"Do you see the rocks?"

"Not yet," her brother answered. "But we'll soon be there."

They did not reach them, however. On and on they rode. The sun went down behind a bank of clouds.

"Oh, dear!" sighed Janet, "I don't like this," and her voice sounded as if she were going to cry.

"We'll soon be back at the rocks, and then I know the way home," said Teddy, as bravely as he could.

But they did not reach the rocks. Up the hollows and across the hills they rode, over the broad prairies, but no rocks did they see. At last the ponies began to go more slowly, for they were tired. It grew darker.

Ted looked anxiously about. Janet spoke softly to him.

"Teddy," she asked, "are we--are we--lost?"

For a moment Teddy did not answer. Then he replied slowly:

"Yes--I guess we are lost, Janet!"

CHAPTER XIX

THE HIDDEN VALLEY

The Curlytops were in trouble. It was not the first time they had been lost, no indeed! But it was the first time they could remember being lost so far away from home, and in such a big place as a Western prairie. They did not know what to do.

"Don't you know the way home?" asked Janet, still keeping close to her brother. It was getting dark, and, somehow, she felt safer near him, even if he was only a year older than she was.

"I'd know the way home back to the ranch house if we could find the rocks with the cave where Clipclap was," Teddy replied.

"Let's look for them some more," suggested Janet. "If we don't get home pretty soon we'll be all in the dark and--and we'll have to stay out here all alone."

"Are you afraid?" asked Ted, looking at his sister.

"Yes. Won't you be?"

"Pooh! No!" he exclaimed, and he talked loudly, perhaps just so he would not be afraid. You know a boy always whistles very loudly at night when he is walking along a dark place alone. And if there are two boys they both whistle. What girls do when they walk through a dark place alone I do not know. Maybe they sing.

Anyhow Teddy talked very loud, and when Janet heard him say he was not afraid she felt better.

"But will we have to stay out here all night?" she asked.

"I guess so," Teddy answered. "But it'll be just like camping out. Daddy and Uncle Frank and the cowboys are going to stay out."

"Yes, but they've got something to eat," objected Janet, "and we haven't anything. Not even a cookie--lessen you've got one in your pocket, Teddy."
