"You never can do it!" declared the man who had offered the objection. "You never can do it in this world. You'll be off in no time, and it's a long fall to the river. You can't do it!"

"Can't I?" asked Joe coolly. "You come and watch me. I'm going to ride my motor-cycle across the railroad trestle bridge on the single rail!"

Several in the crowd looked at him admiringly, while others shook their heads.

"He'll kill himself!" murmured one old man.

"He sure has got nerve!" exclaimed a boy, admiringly.

Meanwhile a crowd of villagers followed Joe as he rode off in the direction of the railroad. It was his only chance of getting to the circus on time.

CHAPTER XXI

IN STRANGE PERIL

Joe was running his machine at reduced speed as he went off in the direction that had been indicated as the location of the railroad tracks. Beside him ran some of the more fleet-footed of the youths of the town, and behind them came some men. All were hurrying to see if Joe would make good his boast.

Yet, it was not so much a boast as it was a determination to do this risky act in order not to be late at the circus and so disappoint a big crowd and cause trouble for the management.
