And the first speaker followed the suggestion. The others fidgeted about for a few minutes.

"Let's get out, then," said one of those who remained. "Those kids are tied up safe enough. No need to stay here. Let's get some fresh air and look to see if she's coming."

And in a moment the station was empty, save for the two prisoners.

Jack acted on the instant. In a second he was at the key, pounding away, and calling B-D, B-D, in frantic efforts to get an answer and have the limited stopped and help rushed.

"O-K—" came the answer at last, and in a frenzied rush, but with the hand of an inexperienced operator, Jack sent the story over the wire. He had won!

He was in time, he was sure. The train had not yet passed the last telegraph station before Haskell Crossing, and it would be stopped before it could rush on to destruction. Then, swiftly, he rushed over to the chair in which Hudson was strapped, and quickly cut the ropes that held the operator. As quickly he snatched the gag from his mouth.

"Gee, that was great!" cried Hudson. "I didn't know you knew how to handle a key. You did fine!"

"I guess they got the message in time to stop the train. Don't you think so?"

"Listen to it now."

The key was clicking away furiously. The sounds were so fast that Jack, who was only an amateur and a beginner as a telegrapher, after all, could not understand.
