My hand shook perceptibly, but still I delved; after a while standing in the large hole I had made. With the deepening of the hole, which was about six feet square, the evil smell increased; and I lost all doubt of my imminent contact with the hellish thing whose emanations had cursed the house for over a century and a half. I wondered what it would look like—what its form and substance would be, and how big it might have waxed through long ages of life-sucking. At length I climbed out of the hole and dispersed the heaped-up dirt, then arranging the great carboys of acid around and near two sides, so that when necessary I might empty them all down the aperture in quick succession. After that I dumped earth only along the other two sides; working more slowly and donning my gas-mask as the smell grew. I was nearly unnerved at my proximity to a nameless thing at the bottom of a pit."
