The figurative language that is used in this excerpt is hyperbole, since hyperbole is the exageration of things and words that are not meant to be taken literally in order to make a point, he writtes about the whole country, and then exagerating proceeds to ennumerate all the possible geographic locations like north, south, and geographical characteristics to make a better description.
The first analogy is abstract. The second analogy is concrete. Shakespeare: plays:: Mark Twain: Novels; screen: computer:: face: watch. Sorry, I'm not sure how to prove the concrete/abstract part but I'm sure that I'm right.
