The people
We follow the fog as it interacts with three types of people:
- Greenwich pensioners (retired sailors)
- Skipper (captain of a boat)
- Apprentice (working for the skipper)
The category
You might notice that all these people are from a single category: they are all sailors.
(In the same way that the things in the previous snippet were all from the category of 'boats', Dickens is being systematic in his description.)
The axis
You might also notice that once again this list isn't random; it's organised along an axis of age (old, middle-aged, young).
The places
Each of these people are put in a location that tells us a little bit more about the world:
- The pensioners wheezing by the fireplaces in their wards (which are communal halls provided by the navy, where pensioned sailors could live).
- The skipper is down in his cabin.
- The apprentice is shivering up on deck.
Again, notice how each of these places tells us something about the station in life of each of these groups of people.
