The midday dinner was served, the officers eating at the same time, though sitting apart from their men. As they finished, Captain Foster said:

"Overton, I shall leave you in command of the camp this afternoon. I shall take Terry with me on a tramp through some of this surrounding country. I want to locate other contraband guns or cartridges, if I can. Except for necessary duties let the men rest. While we are on this duty most of the work will be done at night. Sleep a part of the afternoon yourself; one of the non-commissioned officers can look after the camp, and call you at need."

His sole sleep lately having been for an hour the night before, Lieutenant Hal needed no urging to seek a cot in the wall-tent set apart for the use of the officers.

"When will you sleep, sir?" Noll ventured to ask.

"When I have time," replied Captain Foster, stifling a yawn and smiling. "This will not be the first time that I have worked for forty hours without sleep."

But the afternoon prowl revealed no more rifles. There was another surprise. At Agua Dulce were fourteen boats belonging to private owners—all the craft at the village water front. Five of the boats were owned by Mexicans. Somewhat disappointed, Captain Foster and Lieutenant Noll returned to camp.

At the evening meal, just before dark, Captain Foster remarked:

"I've posted a corporal and a guard to see that none of the boats leave shore until they've been found to contain no freight that looks like munitions of war. To my surprise none of the Mexicans showed the slightest interest in my doings. It begins to look as though they have no intention of trying to ferry arms over the frontier at present."

"Are there any steam craft at this point, sir?" inquired Lieutenant Hal.

"Nothing of the sort, Mr. Overton."
