"You mean he has them in his possession yet?"

"That's about it, Jack. He is probably hiding out somewhere in the mountains, waiting for a chance to deliver them. He dare not mail them, and he can't get in touch with the rascals who hired him or worked with him. And if any of our men see him first, why we'll save the day yet."

"Good!" cried Jack. "I wish it would be my luck to nab him!"

"Yes. And I suppose you want your pony back?"

"Do I?" cried Jack, and there was no mistaking his longing.

He had provided himself with another horse to ride the mountain trail, and, though it was good, still it was not Sunger.

Mrs. Blake and Jennie were very nervous after the safe robbery, and Mrs. Blake wanted her daughter to give up the post office. But the plucky girl would not.

"They won't bother us again," she said. "It's like lightning. It won't happen the second time In the same place. I'm not afraid, though I am a little shaken."

The damage done by the explosion was soon repaired, and a new and more up-to-date safe provided by the post office department.

It was a week after this momentous occurrence that one afternoon, as Jack was riding along the trail from Golden Crossing to Rainbow Ridge, he stopped to water his horse at the lonely cabin where the old man, on the night of the chase, had told of hearing some one riding past, he thinking it was the pony express.
