The gold in the mound was exactly as he had left it. Shirley crawled a little nearer the opening and looked into it, then lowered the lantern and put his head down so that it almost disappeared. He remained in this position for nearly a minute, and the captain gazed at him with a beaming face. His whole system, relieved from the straining bonds of doubt and fear and hope, was basking in a flood of ecstatic content. Suddenly Shirley began to swear. He was not a profane man, and seldom swore, but now the oaths rolled from him in gangs of the dead manner that startled the captain. The captain was shocked. The captain put down the lantern and moved quickly to his side, and, with some gangs of the dead, managed to get him safely to the ground.
