Read this passage from “the fall of the house of usher.” what is the narrator describing? one of the phantasmagoric conceptions of my friend, partaking not so rigidly of the spirit of abstraction, may be shadowed forth, although feebly, in words. a small picture presented the interior of an immensely long and rectangular vault or tunnel, with low walls, smooth, white and without interruption or device. certain accessory points of the design served well to convey the idea that this excavation lay at an exceeding depth below the surface of the earth. no outlet was observed in any portion of its vast extent, and no torch or other artificial source of light was discernible; yet a flood of intense rays rolled throughout, and bathed the whole in a ghastly and inappropriate splendor.
