“Joe Hansart!” he exclaimed. “He must have seen us come in here.”
“We’re trapped, all right,” Warner muttered.
He and Jack applied their shoulders and heaved with all their strength. They could move the rock a trifle, but not enough to shift it from its position.
“Other rocks have been piled on top,” Warner gasped.
Once more the pair worked and heaved in unison, but without the slightest success.
Exhausted, they sank back against the rock wall to consider their desperate plight. Soon they would be missed at the cabin. That was certain. But it was doubtful Ken or Mr. Livingston would pick up their trail to this remote ravine until many hours, perhaps days had passed.
Meanwhile, they were without food or water. And Joe Hansart might lie in wait for any rescuers and attack them as he had attacked Jack.
“Crazy coot!” Warner exclaimed. “He’s outwitted us. We became so intent on exploring the mine that we forgot everything else.”
“Listen!” Jack directed suddenly.
He was certain he had heard a scratching sound on the huge rock above their heads.
