CHAPTER XXVI
TURNING THE TABLES
The constant straining caused Fred to perspire freely, and after many vain efforts he succeeded in catching the rope which was around his wrists, under the point of a projecting limb of the tree.
Now he had a purchase, and by a mighty effort at the moment when Gus made a more than usually vicious lunge, slipped one of his hands from the bonds, thanks to the perspiration which moistened the strands.
He did not take immediate advantage of his freedom. It was essential to await a favorable opportunity, and this came when Gus knelt before him for the purpose of pricking the apparently helpless boy with the blade of his knife.
Fred could not arise; but he flung both arms around his tormentor's neck, hugging him so close as to prevent the latter from using his hands.
For an instant his surprise was so great that he remained motionless; but before Fred could take any advantage of his inactivity Gus recovered from the shock to exert all his strength, and began to free himself.
Under ordinary circumstances Fred would have been no match for his captor; but now the knowledge of what was to be gained lent him great energy, and he clung to him with desperation.
"Let go, or I'll stab you with this knife," Gus shouted; but Fred was too careful of his wind to make any reply.
