She broke silence so swiftly that the words seemed to leap to her lips.

"There is one, dear friend," she said, with a warm upflash of strong emotion; "one that neither you nor I, nor any one can overcome!" She pointed down at the boulder-riven flood churning itself into spray in the canyon pot at their feet. "I will measure it for you—and for myself, God help us! Rather than be your wife—the mother of your children—I should gladly, joyfully, fling myself into that."

The motion he made to catch her, to draw her back from the brink of the chasm, was purely mechanical, but it served to break the strain of a situation that had become suddenly impossible.

"That was almost tragic, wasn't it?" she asked, with a swift retreat behind the barricades of mockery. "In another minute we should have tumbled headlong into melodrama, with poor Mr. Wingfield hopelessly out of reach for the note-taking process."

Ballard accepted his defeat with what philosophy he could muster, and explained the technical detail. Then the others came up, and the buckboards sent down from Castle 'Cadia to take the party home were seen wheeling into line at the upper end of the short foothill canyon.

"There is our recall at last, Mr. Ballard," gasped the breathless chaperon, "and I daresay you are immensely relieved. But you mustn't be too sorry for your lost day. We have had a perfectly lovely time."

"Such a delightful day!" echoed the two sharers of the common Christian name in unison; and the king's daughter added demurely: "Don't you see we are all waiting for you to ask us to come again, Mr. Ballard?"
