A heavy hand grasped his shoulder and swung him around, while old Bob West, panting for Breath, exclaimed: "Stop, you fool--stop! The other one is running." "The other one!" echoed Arthur, wonderingly.
"Of course.

Bill Sizer was sure to run; he's a coward, as all bullies are.

Quick, Weldon, save the day and your reputation or I'll never stand your friend again." Arthur understood now.

He turned and ran back faster than he had come, swung into the lane where the crowd was cautiously peering from the shelter of the buildings, and waving his pistol in a reckless way that made Bob West shudder, he cried out: "Where is he?
Where's Sizer?
Why don't he show up and be shot, like a man ?" No Sizer appeared.

He was even then headed cross-lots for home, leaving his friends to bemoan his cowardice.
