Slowly and silently after that the students followed the trail, through the snow and over the wind-swept rocks. They passed under some tall trees, crossed a frozen-over gully, and then came to where a pile of rocks appeared to bar their further progress.
"They passed along this way!" whispered Dave, pointing to the footmarks, close to the base of the rocks. "Go slow now, or——"
"Hush!" interrupted Roger. "I hear voices."
"I see a cabin, just beyond the turn of these rocks," said Henshaw. "The two men must be there."
