MYSTERY IN THE AIR

"RUSH, I owe you an apology. Had we listened to you, the company would have saved several thousands of dollars in damages that they will now have to pay," said the superintendent.

This conversation took place on the day following the accident in section twenty-four L. It had been a serious affair. The entire dome of the drift had caved in, starting from a crack in the rocks which the Iron Boy had pronounced dangerous. At the time of the cave-in, the drill-man had been operating the diamond drill. The vibration had loosened the rocks and the whole roof had collapsed. The drill-man and his assistant had been killed, and nearly every other man in the drift at the time had been injured.

The unfortunate miners were quickly dug out, Steve Rush working in the dangerous drift at the imminent risk of losing his own life, with rock and ore showering about him almost every second of the time. For a time it was feared that the whole length of the tunnel would cave in, but under the direction of the superintendent fresh pillars and lagging were quickly set in place, saving the mine from more serious disaster.

"I am afraid," continued Mr. Penton, "that the mine captain in the Red Rock will be reduced to the ranks, or dropped altogether as the result of this. It is a matter that the president will have to decide."

"I am sorry, sir, if I have been the cause of trouble for him."

"Cause? Why, if he had followed your advice the disaster would not have occurred. I have made a report of the entire matter, giving you full credit. I also want to ask if you have inspected the other drifts in your shift."

"Yes, sir."

"Do you consider them safe?"

"Yes, sir. Of course, a crack is likely to develop at any time."
