"I guess I can ride the railroad," said Joe. "What sort of a bed is it—cracked stone?"

"No, cinders."

Joe was glad to hear that, for cracked stone would have worked havoc to his tires.

"He can't ride no railroad line," declared another man, positively.

"Why not?" Joe wanted to know.

"You can't ride over the railroad trestle, and it's more than a mile long, counting the approaches. If you walk you won't make any better time than if you went around the long way. You can't ride that machine over the open ties. It would rattle it all to pieces. The only way you can do is to walk and push it."

Joe thought for a moment.

"I think I can ride the trestle," he said.

"How?" demanded the man.

"By keeping on the steel rail. That's smooth enough."
