"Well, you can knock me for a gool, if it isn't the Whistling Lieut.!" he cried eagerly. "What are you doing in this teeming mart of trade?" he added, as he glanced at Baldy Jennings staring open-mouthed at the meeting and beyond him to the few coatless, vested, bearded favorite sons who leaned against the sagging building.

Courtlandt had laughed. When the fog of surprise had lifted he had seen that the years had not changed Nelson. His black eyes were as keen as ever, his little mustache had the same moth-eaten effect, the network of veins on his slightly bulbous nose were redder perhaps, and he was in civilian clothes. That realization wrinkled Steve's brow in perplexity.

"What are you doing here? Last I heard you had joined the regular army and were stationed somewhere around Phila——" Perception of the situation came in a blinding flash. Nelson's eyes met his steadily.

"There are some occasions when a soldier appears in mufti. Especially when he is passing as the newly appointed division superintendent of a railroad." Steve drew a breath. So that was it. His eyes traveled over the train. Which was the treasure car? Obviously the one in the middle which looked like an ordinary baggage-car. The rest were brilliantly lighted coaches, from the windows of which eyes peered out curiously, indifferently or interestedly as the temperaments and minds behind them dictated. His glance came back to Nelson.

"You're the man I'm looking for. I've lost some cattle, and I'm going up the line a way to look for them. I must give you all particulars. I'm counting on you to help me, if there should happen to be any rough stuff pulled off, see?"

The two men had stood apart from the confusion of the station. The rain beat down. Over among the mountains thunder and lightning held high carnival. Courtlandt drew Nelson into the lee of the building. He struck a match and held it above his pipe till the wood burned down to his fingers. In the flickering light he and the superintendent, pro tem., had regarded one another steadily. Nelson moistened his lips:

"Sure, I see, Steve. Glad to have you along." He raised his voice as one of the train hands approached. "Make yourself comfortable in my quarters. Perhaps I can find a couple to make up a little game."

Courtlandt was quite unconscious of the rumble of the train as in imagination he relived the time he had spent waiting for Nelson to join him in the double compartment which had been fitted up as an office for the superintendent. Minutes seemed hours. When he did come the smile had left his lips. His eyes were stern. He closed the door with a bang.

"Deal out what's coming, quick!" he had commanded and Steve had told him almost word for word what Mrs. Simms had written. "You're sure of this?"

"I've given the message as it came to me. The person who sent the warning had every reason to keep mum."
