“It was lost, but I found it again,” explained Nestor. “There’s millions in it. It’s up in the mountains, about a hundred miles from Tucson. The gold is there, but it’s hard to reach.

“Now what I want to know is, can you boys go there, or near there, in your choo-choo cart? If you can, and we are successful, there’s a chance for us all to make our fortunes, for I’ll give you boys a share apiece for what you did for me when I was in trouble.”

“I guess we can go,” said Jerry.

“It’ll be a hard trip, full of trouble an’ some danger,” warned the miner.

“We’ll risk it,” said Ned.

“When can you start?” asked Nestor.

“Let’s go right now!” exclaimed Bob, with such earnestness that the other laughed.

“To-morrow or next day will do,” said Nestor. “I have a few things to attend to. I’ll meet you here, say day after to-morrow.”

At the agreed time Nestor was on hand. In the meantime the auto had been thoroughly overhauled, put in shape for a long, hard trip, and extra supplies purchased. It was a bright, sunny day when the start from Chicago was made.

“Let her go!” exclaimed Nestor, as he climbed into the rear seat with Bob.
