She shook her head:

"These are not prehistoric mounds."

"Why not?"

"Because they have been freshly made."

"How do you know?"

"The earth is freshly upheaved; great trees, partly uprooted, slant at every angle from the sides of the enormous piles of newly upturned earth; sand and stones are still sliding from the raw ridges."

She leaned nearer and dropped her voice still lower:

"More than that," she said, "my father and I both have seen one of these huge circles in the making!"

"What!" I exclaimed, incredulously.

"It is true. We have seen several. And it enrages father."
