"Well, you have got nervous, Mrs. Newman! I'll just send three or four of the boys out to meet her. Eh?"

"Oh, yes, do!" cried Katherine. "I shall feel easier. Good-by!"

Dick Freeman dropped the receiver and hurried into the neighboring bunk-house.

"Boys," he said quietly, "Mrs. Newman just 'phoned me that Miss Tuttle went to walk at sunset, to be gone half an hour. She ain't got back yet. She is alone. Will some of you come with me?"

Every hand of cards was dropped before Dick was half through his statement. In less than twenty minutes twenty cowboys were circling slowly out into the desert. For two hours Katherine paced from the living-room to the veranda, from the veranda to the corral. She changed her light evening gown to her khaki riding habit. Her nervousness grew to panic. She sent Li Chung to bed, then she paced the lawn, listening, listening.

At last she heard the thud of hoofs and Dick Freeman dismounted in the light that streamed from the open door.

"We haven't found her, Mrs. Newman. Has Mr. Newman got back? I think we must get up an organized search."

Katherine could feel her heart thump heavily.

"No, he hasn't. Have you found her trail?"

"No; it's awful hard to trail in the dark, and the desert for miles around the ranch is all cut up with footprints and hoof-marks, you know."
