"No, no, Maud, that would never do. Let us await the confidence of our parents, and try, in the meantime, to pick up what facts we can. Who knows," he added, "but we may stumble on to some great discovery?"

Little, indeed, did he suspect the great revelations which the day held in store for them, and that events were about to transpire which would change the tenor of their whole lives.

At Mrs. Warlow's entrance the conversation took on a less sombre hue, and when she told of the news confirming the great land-sale which was soon to be held at the land office—a fact which she had learned from the Estills—it was proposed to take a drive out over the country north-east, and find a section for Maud and Rob, which the colonel would buy for their benefit at the sale.

Accordingly, after dinner, as the weather had cleared, the Warlow family drove out and viewed a well-watered, rolling tract, equal in extent to the farms of the colonel and Clifford. After an hour spent thus, it was thought advisable to drive on westward and examine a country which, in their busy farm-life, had never been viewed, save at a distance.

On arriving at a point about three miles west of their home, they drove down into a narrow valley or glen, clothed with tall blue-stem and rank sunflowers, now beginning to unfold their golden blossoms. This jungle of vegetation was woven together by the slender, leafless tendrils of the love-vine, which threw a veil of coppery red over the brilliant green of the other vegetation.

While driving slowly through this almost impervious mass of vegetation, they discovered a winding but well-beaten trail or pathway, leading on down the valley, and which, out of pure curiosity, they followed until it disappeared in a thicket of plum-trees at the base of a low cliff of magnesian limestone.

As they paused at the scrubby grove, wondering what could have made the path, Clifford sprang out of the carriage, saying he would like to investigate the matter, and disappeared among the trees. He was gone so long that, after they had called him repeatedly, Rob was on the point of starting in search, when Clifford reappeared. As he sprang into the carriage their questioning was forestalled by his saying that the path was possibly made by wolves, and that he had been examining the cliff, but had not succeeded in finding their den.

He appeared so pale and agitated, however, that Maud regarded him suspiciously; and when the horses flew up the glen along the winding pathway and through tangled thickets of blue-stem and sunflowers, she managed to ask in a whisper:—

"What have you discovered, Cliff?"

"A clue to the old mystery—but wait," he whispered in reply; and in silence they drove rapidly back to the Warlow homestead.
