trail by reason of the noise the boys made in their mad flight toward the trees.
The men had the advantage in that they knew every inch of the rocky ground. The boys had to proceed more cautiously because it was unfamiliar to them, especially to Chet and Biff.
Biff was limping along in the rear and Joe purposely slowed down his pace so as to remain with his chum. But the delay was fatal. Out of the darkness came one of their pursuers, and with a growl of triumph he flung himself at Biff.
His arms encircled the lad's legs in a perfect tackle and Biff went down with a crash. Joe wheeled about and plunged upon them, striking out desperately to fight off Biff's attacker. They struggled fiercely in the darkness. Joe felt his fist crash into the man's face and he heard a grunt of pain. Biff was wriggling out of his assailant's grasp, and the boys might indeed have made their escape had it not been that the other men came running up out of the shadows.
With a roar of fury, two of them plunged at the boys and hauled them away from their comrade.
"After the other two!" shouted a voice, which they recognized as that of Red, "They're heading for the bushes!"
