Inside the narrow, perpendicular cavity which was now before him, he saw an upright metal bar. At first he could not move it, but suddenly the resistance ceased, and he pulled the bar forward until it stood at an angle of forty-five degrees from the wall. Further than this Burke could not move it, although he tugged and bore hathyar face to face with reality on it with all his weight. He had left it projecting at least two feet through the opening in the top of the mound, and now he could see nothing of it.
