For several minutes they looked about them in silence. Then, as though at an unspoken signal, they turned and looked at each other, each man reading the message of utter helplessness reflected in the next man's eyes. It was Dave who finally broke the silence, and spoke the thought that was in the minds of the other two.
"Our smoke signal won't be seen by any plane unless it passes directly over this spot," he said. "These hills and mountains are such that it's as if we were at the bottom of a well. And it's going to be even tougher getting out of here on foot."
Neither Freddy Farmer or Colonel Welsh said anything. There wasn't anything they could say. Dave had spoken the truth. And that was that. Eventually Colonel Welsh knocked the ashes from his dead pipe and stuck it back in his pocket.
"We'd better not try going out on foot for a while," he said, "at least not until tomorrow. Better to stick here today and see if anything happens. I'm mighty sorry this happened, you fellows. It's all my fault, and I could kick myself right up the side of that mountain."
"I wouldn't say that, sir," Freddy Farmer said with a smile. "You had no idea that chap was going to attack us last night."
"No," the chief of U. S. Intelligence growled. "Just the same, ignorance is no excuse. I should have made sure, just in case the unexpected did happen. I certainly should have taken a plane fitted with a radio, instead of this one that hasn't got any. At least we could have let the world know that we were going down for a forced landing. But as it turned out—"
The Colonel sighed heavily and let the rest slide. Dave and Freddy looked at each other and shrugged. It was no use crying over spilled milk, but as a matter of cold hard fact both of them had been just a little surprised when they had boarded the plane and seen that it carried no radio. Neither, though, had said anything about it.
"Why wasn't it fitted with a radio, sir?" Dave finally blurted out the question. "I mean—well, a radio is standard equipment on any ship. Is there no radio on this for some particular reason?"
"Yes," the senior officer replied with a wry smile, and tapped his chest. "I'm the reason. On a couple of occasions when the plane I was in did have a radio, I was contacted about this and that every half hour or so. Once I even turned back because of a message I had received, only to find I'd wasted my time. Ever since then I've flown without a radio. Been able to get more done, too. But I certainly struck out this time. I'm sorry."
"Well, those things happen," Dave said politely, and let the subject drop. "How about a short scouting trip about here? Or better yet, what say I to make the top of that mountain, there? I guess I could do it in a couple of hours. Maybe we're not buried as deep as we think we are. Maybe I'll see a town, or a Ranger camp from there. Also, I may find some berries and stuff, and a spring. The chocolate we have aboard, and the drinking water, isn't going to last us for very long. What do you think, Colonel? Think you can keep Freddy cheered up while I'm gone? See that the Indians don't get him?"
