When the chief understood this he was greatly indignant, and began to protest in loud tones. Bob checked him peremptorily. He felt that if he gained admittance to the fort precious time would be wasted if he had to give orders to Sing-Cheng through Ah-Sam, while if two men were unable to effect their purpose it was unlikely that three would succeed. He did not consider it necessary to argue with the chief, but pacified him by saying that, if Ah-Sam crossed over, he was to take the Chinaman's place at the end of the cleft and watch carefully lest it proved necessary to cover the retreat of the two from the other side.
All was now ready. But Bob waited for nearly an hour until the moonlight fell full upon the platform and the staple above it. Then he rose, placed his right foot in the loop of rope from which he had removed the experimental bundle, and stood on the ledge, grasping the rope firmly with his right hand. It was an anxious moment. He felt a sudden shudder run through his body as he hesitated on the brink, looking at the black gulf before him, and realizing that he was in very truth taking his life into his hands. But his hesitation was but momentary. With a determination and a hope that were themselves prayer he set his lips, pulled the rope taut, and dropped, his companions holding their breath as they watched him. There was little jerk as he fell, but it seemed an eternity before the swift motion through the air began to slacken on the upward swing. Suddenly, just as he felt that he was coming to a stop, he saw the staple above him slightly to his right. He jerked himself up and sideways in the effort to catch it with his unoccupied left hand; he touched it with the tips of his fingers; then the sagging rope became taut again; he fell swiftly downwards, felt a slight jerk at the lowest point of the rope's course, twirled round and round, and grazing the wall, it seemed by an inch, shot upwards towards the ledge. He had only time to wonder whether Ah-Sam would catch him with the loop when he again came to rest and began to fall downwards. There was a sudden constriction about his waist; he felt a sharp pain; then, to his relief, though to his discomfort also, he was steadily hauled in, and landed breathless, exhausted, and dazed on the ledge beside Ah-Sam.
