“I hope the men have left it open,” he said to himself.

He was almost running now. Suddenly something black loomed up in front of him, as he could see by the glare from a near-by electric lamp. He put out his hand and touched something cold and hard.

“It’s the air lock!” he exclaimed. “And the door is shut!”


CHAPTER XIV
LARRY’S SUCCESS

For a little while Larry felt a sense of bitter disappointment. After all his effort and the plans of Mr. Emberg and Mr. Newton, to have the venture fail was, he thought, a hard thing. And fail it seemed the scheme must, since unless he could soon get to the surface and telephone the news, it would be too late for the day’s paper and the others would have it to-morrow. Then the Leader would not score “a beat.”

The boy went close to the big iron door and examined it as well as he could in the dim light. It was a massive affair with ribs of steel and swung on heavy hinges. It was built to withstand heavy pressure, though there was none on it now. It was fastened by means of a peculiar catch that was operated from within.

Larry passed his fingers around the edge. He began on the side where the hinges were, since he could not see very well. Not a crack was to be felt. Then, as his hand came around on the other side, he gave a start. He was aware of a slight opening.

“The door is not shut tight!” he cried. “Maybe I can open it!”

He felt around until he came to a place where the opening was widest. As he had discovered the door was not quite shut tight. He put his fingers into the crack and pulled with all his force.
