"And did my pony get home safe?" asked Jack eagerly. Sunger meant much to him.

"He's all right," said the hotel keeper. "I had one of my boys look after him. He's a bit winded, that's all. Smart little horse, that! If ever you want to sell him, Jack—"

"You needn't ask. I don't," was the quick answer. "But what about my father, Dr. Brown? Is he worrying, much?"

"Well, some, of course, Jack. But I gave him Some quieting medicine, and he'll soon hear the good news. He's much better these last few days."

The men questioned Jack at length about the appearance of the hold-up men, but he could not give a very clear description. No one recognized them as any one they knew.

"But we'll get a posse out after them as soon as we get back to town," declared Mr. Perkfeld. "We'll show them they can't hold up the pony express and get away with it."

"They didn't get away with it—that's the joke," said Mr. Argent. "I guess Jack is right. They probably feared pursuit, or might have gotten an alarm, so they dumped the stuff in the old mine hole and rode away, intending to come back later. Only Jack got ahead of them."

"That is I hope I did," interposed the pony express rider. "Maybe they have looted the bags, though they feel as full as when I look them from Golden Crossing."

"Well, we can soon tell," replied Mr. Argent. "It's getting light enough to see. The locks have been forced, anyhow, so it isn't any crime for us to open the United States' mail under these circumstances."

Jack and his rescuers gathered around while the miner opened the bags. They were filled with letters, papers and small parcels.
