But Lee had no time to speculate on the Mexican's identity. The liquor was the important thing. The man stood motionless, holding in his left hand the half-filled cup that gave off a pungent, sickening smell of whisky; his eyes were intent on the engineer. Behind Lee, Carrigan was already herding the others from the tent.

"Where did you get that stuff?" Bryant demanded. But as the Mexican only shook his head, he changed to Spanish. "Trying to start a big drunk here?"

"To-morrow is a fête day, señor," was the reply. "A friend made me a present; I share it with the others. Besides, in cold weather it keeps one warm."

"How long have you worked here?"

"Three days."

"There's a camp order: 'No liquor allowed in camp.' You can't say that you don't know it, for it's posted everywhere on placards in English and in Spanish."

He received no response. A faint shrug of the shoulders, perhaps. The Mexican's glistening, sinister eyes, on the other hand, continued as rigid as orbs of polished agate, and his face as expressionless.

"Well, we'll lock you up and see if we can learn who your 'friend' is that sent this barrel in," Lee stated.

There was a slight movement of the man's elbow.

"Watch him—his right hand!" Pat cried, sharply.
