"We'll see that you get enough to eat if that is what worries you," Merritt went on to say consolingly; and at that the fat scout managed to smile a little.

"Well," he remarked with a sigh, "if the rest of you can stand for it, I guess I'll just have to, that's all. But, jiminy crickets, things look pretty shady after coming straight from a nice clean home!"

"You'll have to put up with lots worse than that, Tubby; so cheer up," said Andy. "And now, what is the first thing on the program, Rob?"

"Clean up the best we can, and rest till after we've had our dinner," the other advised. "Then we'll try to get an interview with the commander of the forces here, and see what he thinks we'd better do."

"Huh! like as not he'll tell us we must not dream of venturing across to the other side, unless General Villa happens to be in Juarez right now, which I reckon would be too good luck," Tubby replied disconsolately. "And I hope, Rob, that if he does talk that way he won't influence you to call it all off. Think what silly guys we'd feel like, starting back home without even making a try to invade Mexico!"

"Don't let that keep you on edge, Tubby," the patrol leader told him; "you ought to know me by this time, and that I never give up a thing I've set my mind on till the last horn blows. We've started on this business of your Uncle Mark's; and we'll see it through, or know the reason why!"

"Hurray! them's my sentiments!" exclaimed Andy, and even Merritt waved his hand above his head, as though he fully agreed with the other comrades; so Tubby was able to appear at ease once more, as a great load had been removed from his heart.

When they had partaken of a wretched dinner that made Tubby look quite blue because there was hardly a thing that seemed to taste right, the four boys started out to look the border town over. They cast frequent glances across the guarded bridge connecting El Paso with the Mexican shore of the river, and finally asked of a passing soldier the way to headquarters.

Already they had learned who was in command at El Paso at that time, and had even glimpsed the general at a distance. It happened that they found the commander at leisure, which was a wonder, for he had his hands full during these troublous times trying to keep the peace, when there were so many chances of Americans and Mexicans coming into armed conflict along the river for miles.

The officer looked them over as they were ushered into the room. Rob had been wise enough to send in a note telling who they were, and that they wished to consult him on a very important piece of business.
