As soon as it was seen that a hasty and quick search was not going to result in the capture of the robber and his confederates, a well-planned organized hunt was instituted, to take in as much as possible of the surrounding mountain country. Jack could not take part in this, as he had to ride the express route.

At first he feared lest he might be discharged for having been robbed, but, as a matter of fact, technically he was not in the least to blame. The matter taken was not in his charge, but was in the safe in a post office, and his responsibility ended with the delivery of the mail. Nor was Jennie Blake blamed. The post office authorities did not in the least censure her or her mother. In fact they paid them the compliment, and Jack, too, of saying that extraordinary precautions had been taken, but that the robbery had occurred in spite of them.

Another point was that no express stuff was taken, but only United States' mail. And so the express people had no complaint against Jack, or any one else, as they had lost nothing. Such being the case, there was no good reason for displacing Jack, especially as the robbery had not occurred on his route. So those who hoped to get his position were disappointed.

"You can keep right on riding for us, Jack, my boy," said Mr. Perkfeld.
"We're glad to have you. It isn't often we get as plucky a lad as you. And
when your father gets well, and wants his place back, he can have it, and
I'll find an opening for you on another route, if you like."

"I certainly would like!" Jack exclaimed, warmly.

In addition to the posse organized in Golden Crossing and Rainbow Ridge the post office authorities also sent out inspectors and detectives to try and round up the robbers. This was done the day after it occurred, so that within forty-eight hours the mountain trails were being well patrolled by men eager to apprehend the offenders. And in the mountains, off the trails, were others on the same errand. Jack wished he could be with them, but he had to keep to the mail and express route.

As far as Mr. Argent could learn, no use had yet been made of the stolen documents.

"And that is a good sign," he said to Jack. "I've been in touch with matters, and I and my friends would know as soon as some use was made of them. The people who could best use those documents would have an injunction out against us in a jiffy, and be in possession of the mine as soon as they laid their hands on the papers. But they haven't got them yet, that's sure."

"What does that mean?" asked Jack.

"Just this. Those who would gain the greatest advantage from the possession of our papers, which would give them control of the mine, didn't do the actual stealing themselves. They hired these outlaws to do it, and from the fact that no action has been taken makes me sure that the robber who blew open the safe and took the letters, has not had a chance to deliver them."
