When Jana discovered them she turned to the right and tried to circle about them, but Skruk sent one to intercept her and when she turned in the opposite direction, the four spread out across her line of retreat so as to effectually bar her escape in that direction. Choosing any fate rather than that which must follow her capture by Skruk, Jana turned again and fled down the valley and in pursuit leaped the four squat, hairy men of Pheli. At the instant that Jason Gridley had pulled the rip cord of his parachute a fragment of the broken propeller of his plane had struck him a glancing blow upon the head, and when he regained consciousness he found himself lying upon a bed of soft grasses at the head of a valley, where a canyon, winding out of lofty mountains, opened onto leveller land. Disgusted by the disastrous end of his futile search for his companions, Gridley arose and removed the parachute harness. He was relieved to discover that he had suffered no more serious injury than a slight abrasion of the skin upon one temple. His first concern was for his ship and though he knew that it must be a total wreck he hoped against hope that he might at least salvage his rifle and ammunition from it. But even as the thought entered his mind it was forced into the background by a chorus of savage yelps and growls that caused him to turn his eyes quickly to the right. At the summit of a little rise of ground a short distance away he saw four of the ferocious wolf dogs of Pellucidar. As hyaenodons they were known to the paleontologists of the outer crust, and as jaloks to the men of the inner world. As large as full grown mastiffs they stood there upon their short, powerful legs, their broad, strong jaws parted in angry growls, their snarling lips drawn back to reveal their powerful fangs. As he discovered them Jason became aware that their attention was not directed upon him--that they seemed not as yet to have discovered him--and as he looked in the direction that they were looking he was astounded to see a girl running swiftly toward them, and at a short distance behind the girl four men, who were apparently pursuing her. As the vicious growls of the jaloks broke angrily upon the comparative silence of the scene, the girl paused and it was evident that she had not before been aware of the presence of this new menace. She glanced at them and then back at her pursuers. The hyaenodons advanced toward her at an easy trot. In piteous bewilderment she glanced about her. There was but one way open for escape and then as she turned to flee in that direction her eyes fell upon Jason Gridley, straight ahead in her path of flight and again she hesitated. To the man came an intuitive understanding of her quandary. Menaced from the rear and upon two sides by known enemies, she was suddenly faced by what might indeed be another, cutting off all hope of retreat.
