It reminded Shefford of the forest near the mouth of the Sagi. It was so dense he could not see far ahead of Fay, and often he lost sight of her entirely. Presently he rode out of the forest into a strip of purple sage. It ended abruptly, and above that abrupt line, seemingly far away, rose a long, red wall. Instantly he recognized that to be the opposite wall of a canyon which as yet he could not see.

Fay was acting strangely and he hurried forward. She slipped off Nack-yal and fell, sprang up and ran wildly, to stand upon a promontory, her arms uplifted, her hair a mass of moving gold in the wind, her attitude one of wild and eloquent significance.

Shefford ran, too, and as he ran the red wall in his eager sight seemed to enlarge downward, deeper and deeper, and then it merged into a strip of green.

Suddenly beneath him yawned a red-walled gulf, a deceiving gulf seen through transparent haze, a softly shining green-and-white valley, strange, wild, beautiful, like a picture in his memory.

“Surprise Valley!” he cried, in wondering recognition.

Fay Larkin waved her arms as if they were wings to carry her swiftly downward, and her plaintive cry fitted the wildness of her manner and the lonely height where she leaned.

Shefford drew her back from the rim.

“Fay, we are here,” he said. “I recognize the valley. I miss only one thing—the arch of stone.”

His words seemed to recall her to reality.

“The arch? That fell when the wall slipped, in the great avalanche. See! There is the place. We can get down there. Oh, let us hurry!”
