What rhetorical strategies does Poe use in the introduction to "The Fall of the House of Usher"?I need at least five rhetorical strategies.

He uses sound, especially alliteration:  dull, dark, dreary, desolate, decayed depression, dreariness--and this is just paragraph one.

He uses punctuation as a rhetorical strategy: in paragraph two the narrator frequently breaks us his speech, which the text signifies through the dash (--) to indicate his fragmented thoughts brought about by what he sees, the House of Usher.

He uses personification, referring to "eye-windows" twice in paragraph one.

He uses sensory images repeatedly to create mood: the day is "soundless," the trunks of the trees are "white," and there is an "iciness" about him.

He uses analogy: he feels a depression somewhat like the "after-dream" of opium; "it is like "the hideous dropping off of the veil." 

One for good luck:  he uses metaphor in paragraph two when he says "it was the apparent heart of the request."
