Mrs. Mann beat Oliver.

Oliver was about to say that he would go along with anybody with great readiness, when, glancing upward, he caught sight of Mrs. Mann, who had got behind the beadle's chair, and was shaking her fist at him with a furious countenance.

The workhouse board starves the boys, which serves to weed out the weakest and decrease the population.

For the first six months after Oliver Twist was removed, the system was in full operation. It was rather expensive at first, in consequence of the increase in the undertaker's bill, and the necessity of taking in the clothes of all the paupers, which fluttered loosely on their wasted, shrunken forms, after a week or two's gruel. But the number of workhouse inmates got thin as well as the paupers; and the board were in ecstasies.

The master delivers blows (hits them).

The master aimed a blow at Oliver's head with the ladle; pinioned him in his arm; and shrieked aloud for the beadle.
