"Yes. I shall be back some time to-morrow; in the meantime there is nothing to do but to sit tight in the boat. Use my private code if you want to wire me. I don't more than half trust that young fellow, Dix, Callahan's day operator. And, by the way, Mr. Frisbie is sending me a stenographer from Denver. If the young man turns up while I am away, see if you can't get Mrs. Williams to board him." McCloskey promised and dropped off, and the one-car special presently clanked out over the eastern switches. Lidgerwood went at once to his desk and promptly became deaf and blind to everything but his work. The long desert run had been accomplished, and the service-car train was climbing the Crosswater grades, when Tadasu Matsuwari began to lay the table for dinner. Lidgerwood glanced at his watch, and ran his finger down the line of figures on the framed time-table hanging over his desk. "Humph!" he muttered; "Acheson's making better time with me than he ever has before. I wonder if Williams has succeeded in talking him over to our side? He is certainly running like a gentleman to-day, at all events." The superintendent sat down to Tadasu's table and took his time to Tadasu's excellent dinner, indulging himself so far as to smoke a leisurely cigar with his black coffee before plunging again into the sea of work. Not to spoil his improving record, Engineer Acheson continued to make good time, and it was only a little after eleven o'clock when Lidgerwood, looking up from his work at the final slowing of the wheels, saw the masthead lights of the Copah yards. Taking it for granted that Superintendent Leckhard had long since left his office in the Pacific Southwestern building, Lidgerwood gave orders to have his car placed on the station-spur, and went on with his work. Being at the moment deeply immersed in the voluminous papers of a claim for stock killed, he was quite oblivious of the placement of the car, and of everything else, until the incoming of the fast main-line mail from the east warned him that another hour had passed. When the mail was gone on its way westward, the midnight silence settled down again, with nothing but the minimized crashings of freight cars in the lower shifting-yard to disturb it. The little Japanese had long since made up his bunk in one of the spare state-rooms, the train crew had departed with the engine, and the last mail-wagon had driven away up-town. Lidgerwood had closed his desk and was taking a final pull at the short pipe which was his working companion, when the car door opened silently and he saw an apparition.
