The mob hitherto had been passive spectators of the scene, but as the intelligence of the Pickwickians being informers was spread among them, they began to canvass with considerable vivacity the propriety of enforcing the heated pastry-vendor's proposition: and there is no saying what acts of personal aggression they might have committed, had not the affray been unexpectedly terminated by the interposition of a new-comer.

'What's the fun?' said a rather tall, thin, young man, in a green coat, emerging suddenly from the coach-yard.

'Informers!' shouted the crowd again.
