"What is it?" he asked.

"I hear water dripping," she answered. "It's over this way."

She went straight to the spring, following the sound of the dripping water, and found where it bubbled up in a split in the rock. The water fell into a little hollow, rocky basin and there was enough for Ted and his sister to fill their hats. First they each took a drink themselves, though, for the day was warm.

Their hats were of felt, and would hold water quite well. And as the hats were old ones, which had been worn in the rain more than once, dipping them into the spring would not hurt them.

"I guess the pony'll be awful glad to get a drink," said Jan to her brother.

"I guess he will," he answered, as he walked along looking carefully where he put down his feet, for he did not want to stumble and spill the water in his hat.

"Look out!" exclaimed Janet, as her brother came too close to her. "If you bump against me and make my arm jiggle you'll spill my hatful."

"I'll be careful," said Teddy.

They spilled some of the water, for their hats were not as good as pails in which to carry the pony's drink. But they managed to get to the cave with most of it.

"You can give him the first drink," said Teddy to his sister. "I found him, and he's my pony, but you can give him the first drink."
