What are two metaphors in A Christmas Carol by Charles Dickens?

Dickens uses lots of metaphors in this story. To find some examples, take a look at stave 1. First of all, Dickens uses a metaphor when describing Scrooge's character to the reader. Specifically, Dickens compares Scrooge's coldhearted miserliness to cold or frost, as shown in the following lines:

He carried his own low temperature always about with him; he iced his office in the dog-days; and didn't thaw it one degree at Christmas.

This metaphor is effective in emphasizing the negative aspects of Scrooge's character. By portraying him as being so coldhearted that it affects his body temperature, Dickens really highlights this particular character trait.
For another example of a metaphor, take a look at the description of the London streets. Dickens compares the houses, for instance, to "phantoms." By doing this, he emphasizes the impact of the fog. The fog is so thick that it has transformed the appearance of the houses, making them look like ghosts. This metaphor also foreshadows the arrival of the three spirits later in the story.
