Ralph therefore comprehended that it was only over this stretch of road that any special could be expected from the north. Further, he decided that it must be a very important special that could gain the right of way under existing legal complications and interrupt the regular system of the Great Northern.

However, the order was out and Ralph had definite instructions. He made the depot in three minutes, and darted into the private office of the depot master without ceremony.

That official looked nervous and engrossed. He clicked at a telegraph instrument with one hand, while he hastily unfolded and scanned the slip of paper Ralph had brought.

"Very good," he nodded. "Clear tracks to Springfield. If they boost the special along on the other sections as well as we have done on this, and our president can score a mile-a-minute run, he can reach his dying wife in time."

Ralph hurried back towards the switch tower. He fancied he now understood the situation. The brief words of the depot master had been enlightening.

He guessed that the president of the road at a distance had been apprised of serious illness in his family. Perhaps the attendant physician had wired a time limit. If the anxious husband hoped to see his stricken wife before she died, he must exert every privilege he controlled as the head of a great railroad system.

Ralph reflected that he might have been a thousand miles away when he received the anxious summons. Influence and the wires had possibly called half a dozen interlocking lines into service. Even the law had stepped aside, it seemed, to speed the distressed official on his way, via the north spur of the Great Northern.

The 1.05 express steamed out of the depot just as Ralph reached the switch tower.

"That clears the situation," he reflected. "Set the out main for the in switch after she passes. Hark!"

Ralph bent his ear at an unusual sound. This was the echo of a sharp locomotive whistle--to the north.
