He stooped to fill the flask, but he did it clumsily, without his usual care, and drenched his sleeve. The pleasure in her face faded; she continued to watch him, but with ruffled brows. "Oh," she said at last, "I wouldn't have believed you could be so unrelenting; but you are determined to remind me, every step of the way, that you didn't want to stop at Orcas Island. You're the most unsatisfactory man, on a trip, I ever knew. Still, you were different last year, on the Paradise trail."

"Was I? Well, you see, I keep thinking of that man—in the tide-rip; he stopped here at this stream, to rest."

"The man who was wrecked? Did he come up here?"

"Yes, he thought that he was on the mainland. He tried to reach the settlement this way. But there isn't time to tell the story here."

He turned and led the way quickly back to the horses, and they mounted and rode on through the wood. At the foot of the final pitch they left the horses and pushed up over shelving rock to the bald summit. The sun was low in the west and the light touched the houses of a little seaport, eastward on the mainland; and above the craggy heights that overtopped the town a snow mountain caught the glory. Far southward the crown of Rainier seemed to rise like an opal island straight out of the shining sea.

Suddenly Stratton laid his hand on her arm. "Wait," he said, "this is the end. The summit breaks there, a sheer drop of a thousand feet, with a lake below.

"You know," she said. "You've been here before?"

"It is plain enough. Look down."

She looked; but she was obliged to creep another step and drop to her knees before she saw the lake, far, far below, tucked like a great sapphire in a high pocket of the mountain. "Oh," she said, "it seems fathoms deep; and there isn't a lasting snowfield on this mountain. What feeds it?"

He helped her back from the precipice and to her feet. "It is probably one of the Cascades' reservoirs," he answered; "supplied by some subterranean stream under the bed of the Straits."
