"But if there were any need of it I'd do it now," he said, though he would have regretted leaving Jennie, with the prospect of a pleasant evening in her company.

However, as it happened, there was nothing of such importance that it could not wait over until the next day, so Jack did not have to ride away. He put up his pony in the express stable, and he and Jennie spent a pleasant evening together.

Jack was a little worried about his father, and made an early start the next morning, carrying the mail and expressage. He made a quick trip and was relieved, on stopping off for a moment at the Watson cabin, to find that his father had passed a fairly comfortable night, and was considerably better.

"But he can't ride the trail yet," said Mrs. Watson.

"And I don't intend to let him!" exclaimed Jack. "I'm going to be the pony rider for a while."

Dr. Brown confirmed what he had at first said—that Mr. Bailey would be ill for a long time, and when this had become known Jack at once made arrangements to be permanently named as rider between Rainbow Ridge and Golden Crossing. Mr. Perkfeld agreed to this, but, most unexpectedly, some opposition developed among the members of the express firm. It appeared that one of the stockholders wanted the place of express rider for a relative of his. There were several others who wanted the place, and there was quite a scramble for it.

But Jack really had the most logical claim to it, and, as Mr. Perkfeld was able to make the appointment, at least for the time being, it came to Jack.

But there was bitter feeling against him on the part of some unscrupulous men who wanted the place, for it paid well and carried some privileges. It was also an honor.

"You want to watch yourself, son," said Mr. Bailey, rather weakly, to Jack one day, before the lad was about to set out on his ride to Golden Crossing. "Watch yourself, for there is no telling what tricks some of those fellows may be up to."

"Tricks, Dad? What do you mean?" asked Jack in wonder.
