Coketown-Charles Dickens
The city of Coketown that Dickens imagines doesn’t exist: it is an imaginary town. Right from the title C. Dickens focuses the reader’s attention on the coke that is the fuel of that periodThe narrator is a third person omniscient narrator that knows everything about the city and the characters. The novelist appeals to senses like sight, hear, touch, smell in order to render the description more lively. The town is depicted by different colours: red and black are the most frequently used. The colour of red bricks reminds the  colour of  blood and hell, instead the colour of the black canals reminds the darkness of  hell. A binary system is there : red and black, guilt and innocence, artificial and natural.There is a contrast between what is natural (river) and what is artificial like canals.l
 
Alexis DE Tocqueville’s vision of Manchester

Alexis De Tocqueville’s vision of Manchester is an extract from Journeys to England and Ireland.
The novelist, like mr.Dickens in Coketown appeals to sense of sight because he tries to give a mental picture to the reader. There’s an alliteration of letter M in made man to underline the artificiality of canals; there is an opposition between the nature of the rivers and the artificiality of the canals how we can see also in Coketown. The power of man has changed  nature. Manchester is the celebration of the power of the individual versus the masses. There is not a regulating principle and the town seems to have been born without any particular design.
