"It would be more difficult to find a site more annoying to an engineer, whose chief business to economise labour, that than of the men who are scattered in twos and threes through Dublin, sometimes working, sometime wandering wandering their brushes on their shoulders, and sometimes, when they have nothing else to do, sweeping there mud into heaps. ... It is ridiculous to expect that men will work hard to sweep mud off the streets when they know perfectly well that it will be left there, and that in a week or ten days they will have the chance of sweeping it up again."
