Acting almost without conscious initiative, Blake crawled through the window and let himself down to the dust-carpeted and debris-strewn concrete floor. The vaulted cellar was a vast one, without partitions; and in a corner far to the right, amid dense shadows, he saw a black archway evidently leading upstairs. He felt a peculiar sense of oppression at being actually within the great spectral building, but kept it in check as he cautiously scouted about—finding a still-intact barrel amid the dust, and rolling it over to the open window to provide for his exit. Then, bracing himself, he crossed the wide, cobweb-festooned space toward the arch. Half-choked with the omnipresent dust, and covered with ghostly gossamer fibres, he reached and began to climb the worn stone steps which rose into the darkness. He had no light, but groped carefully with his hands. After a sharp turn he felt a closed door ahead, and a little fumbling revealed its ancient latch. It opened inward, and beyond it he saw a dimly illumined corridor lined with worm-eaten panelling.
