Which two sentences contribute to the overall eerle mood of the adapted excerpt from "The Fall of the House of Usher" by Edgar Allan Poe? In this mansion of gloom I now proposed to myself a stay of some weeks. Its proprietor, Roderick Usher, had been one of my closest friends in boyhood.

A letter from him, which, in its wildly insistent nature, had allowed no other than a personal reply. The handwriting gave evidence of nervous agitation. The writer spoke of a kind of illness--of a disorder which oppressed him--and of an earnest desire to see me. As his best and indeed his only personal friend, with a view of attempting, by the cheerfulness of my society, to provide some relief from his malady. ​
