Trapper Bill gripped Frank’s hand in the dark.
“Yer too deep fer me,” he muttered. “I’d never have believed it.”
“Don’t you see the simplicity of the thing now?” said Frank, eagerly. “We have discovered the secret of the valley. It would be easy enough to find our way through it in the daytime if we could locate those spots where the gas comes up.”
“I believe ye,” replied Beaver Bill. “I hain’t ’nuther word ter say. Jest ye go ahead and I’ll foller.”
“Well, what had we better do? Go up the trail or take a walk in the valley?”
