"There isn't much time to build one now," he said. And the Good Wolf grinned from ear to ear.

How they did run—over the grass and up the slopes and down the hollows and over the green gullies! The wind came in hot puffs and shook the tree tops, and the purplish-black cloud looked more ragged than ever, and was growing bigger and coming nearer. By the time they got to the bottom of the long green slope which led to the top of the cliff they had to stop a few moments to take breath.

It was just then that Barty thought he saw a little black head dart out of the long grass and then dart back again.

"Did you see anything near that big leaf?" he asked his companion.

"No," answered the Good Wolf.

"I thought I saw something, but perhaps I didn't," Barty said.

Then they began to climb the long green slope, and it was very steep, and the hot puffs of wind seemed to rush down it to push them back.

"Did you see anything peep out from behind that bush?" Barty said, stopping suddenly again.

"No," answered the Good Wolf, "nothing."

Then they climbed and climbed. The big puffs of wind grew hotter and fiercer, and the cloud spread until it was blotting out the blue of the skies quite fast. Barty's stout little legs were very tired.
