"And yet it isn't," went on Uncle Fred. "It's all right now, but an hour later we may find the water sinking away."

"I'll take some pictures," said Daddy Bunker, who had a camera with him, "and then maybe we can dig up the ground and find hidden pipes, or something like that."

"We'll do the digging to-morrow," said Uncle Fred. "Now I want to show you about the ranch."

So he led them about, showing the six little Bunkers and their father and mother the different buildings, telling them how he raised his cattle and sent them to market, and how he sent out his cowboys to hunt for lost calves.

"There's always something to do on a ranch like this," said Uncle Fred. "You can keep busy all the while. If one thing doesn't happen another will. What with the mysterious spring, the bad men taking my cattle now and then, the Indians running off the reservation and making trouble—well, you can keep busy."

"Could we see the little ponies?" asked Rose. "I'd like to have a ride on one."

"So would I!" exclaimed Russ. "I'd like a pony better than a calf."

"The ponies are over this way. I'll show them to you," said Uncle Fred. "We'll go back by way of the spring. I have some Shetland ponies," he went on to Daddy Bunker. "I raised a few and may raise more. The larger children can ride on them while they're at the ranch."

"That will be fine!" exclaimed Mrs. Bunker. "Oh, I'm sure the children will love it here."

They turned back toward the spring to go to the pony corral.
