Beaudry had no footing to brace himself. Already he was ankle-deep in the quicksand. It flashed across his mind that he could not fight his own way out without abandoning Charlton. For one panicky moment he was mad to get back to solid ground himself. The next he was tugging with all the strength of his arms at the rope. "Keep on the job!" encouraged Charlton. "You're pulling my body over a little so that the weight is on new sand. If Beulah gets here in time, I'll make it." Roy pulled till his muscles ached. His own feet were sliding slowly from under him. The water-bubbles that oozed out of the sand were now almost at his high boot-tops. It was too late to think of retreat. He must go through whether he wanted to or not. He cast one look down the dry river-bed. Beulah was just picking her way across. She might get over in time to save Charlton, but before they made it back across to him, he would be lost. He wanted to scream aloud to her his urgent need, to beg her, for Heaven's sake, to hurry. The futility of it he knew. She was already running with the knowledge to wing her feet that a man's life hung in the balance. Besides, Charlton was not shrieking his fears out. He was calling cheerful words of hope across the quaking morass of sand that separated them. There was no use in making a gibbering idiot of one's self. Beaudry clenched his jaws tight on the cries that rose like a thermometer of terror in his throat. With every ounce of strength that was in him he fought, meanwhile, for the life of the man at the other end of the rope. Before Beulah reached Charlton, Roy was in deeper than his knees. He shut his eyes and pulled like a machine. It seemed an eternity before Charlton called to him to let go the rope. A new phase of his danger seared like a flame across the brain of Beaudry. He had dragged himself from a perpendicular position. As soon as he let loose of the rope he would begin to sink forward. This would reduce materially the time before his face would sink into the sand. Why not hang on and let the horse drag him out, too? He had as much right to live as Charlton. Was there any law of justice that forced him to throw away the rope that was his only hope? But he knew the tough little cowpony could not drag two heavy men from the quicksands at the same time. If he held tight, Charlton, too, would be sacrificed. His fingers opened. Roy watched the struggle on the opposite side of the wash. Charlton was in almost to his arm-pits. The horse braced its feet and pulled. Beulah, astride the saddle, urged it to the task again and again. At first by imperceptible gains, then inch by inch, the man was dragged from the mire that fought with a thousand clinging tentacles for its prey.
