"Who is it?" asked Will.
"I couldn't distinguish faces," was the reply.
"Wasn't George and Tommy, was it?"
"No, two men. They're coming along fast, so we may as well get under cover. We don't know where we're going, but we're on our way," he smiled as he dropped down on his hands and knees and scrambled backward into what had once been the channel of a mountain stream.
Will followed in a moment and, after trying his best to draw the boulder into place, scrambled on after his chum.
"Did you get the rock fixed?" asked Chester as they came together on a little level place probably thirty feet down.
"Couldn't budge it!" was the reply.
"Well, then, we'll keep on going."
"Je-rusalem!" exclaimed Will. "I believe this thing runs clear through the ridge. And that would make it something like a mile long!"
"Of course it does," Chester answered. "This ditch was cut by water, and the water had to find an outlet somewhere."
