Describe the fight Billy has with the gang of boys?

Billy arrives at the depot, unsure why he is scared. The kindly stationmaster gives him the puppies. Billy holds them and cries. He walks through town with them in his gunny sack as people stare and laugh at him. A bunch of children gang up on Billy. The leader pulls the ear of Billy's girl pup, and Billy knocks him down with a punch. He fends off a few others, but soon the gang beats up Billy. The town marshal fights everyone off and helps Billy up. He gains respect for Billy when he learns how long he worked for the pups. He buys Billy his first bottle of soda pop.
