I had lain, according to my own computation, very nearly two days in this black hole, when I felt a movement in the ship which immediately upset my stomach. The vessel, I might suppose, was in the Channel; her pitching grew heavier, the lazarette was right aft, and in no part of the vessel saving the bows could her motion be more sensibly felt. I was speedily overcome with nausea, and for many long hours lay miserably ill, unable to eat or drink. At the expiration of this time the sea ran more smoothly; at all events, the ship's motion grew gentle; the feeling of sickness suddenly passed, leaving me, indeed, rather weak, yet not so helpless but that I could sit up and drink from a bottle of wine and water, and eat a dry ship's biscuit. Whilst I was munching the tasteless piece of sea bread, sitting in the intense blackness, pining for the fresh air and the sunshine, and wondering how much longer I was to wait for Back's summons to emerge, the hatch was raised. I shrank and held my breath, with my hand grasping the biscuit poised midway to my mouth, as though I had been withered by a blast of lightning. A faint sheen floated in the little square. It was the dim lustre of distant lamplight, whence I guessed it was night. The figure of a man cautiously dropped through the hatchway, and by some means, and all very silently, he contrived to readjust the hatch, shutting himself down as Back had shut me down. The motion of the ship, as I have said, was gentle, the creaking noises throughout the working fabric were dim and distant; indeed, I could hear the man breathing as he seemed to pause after bringing the hatchway to its bearings over his head. I did not suppose that the captain ever entered this part of the ship. The man, for all I could conjecture, might be one of the mates, or the boatswain, or the head steward, visiting the lazarette on some errand of duty, and coming down very quietly that the passengers who slept in the cabins on either hand the corridor should not be disturbed. Accordingly, I shrank into the compactest posture I could contort myself into, and watched. A lucifer match was struck; the flame threw out the figure of a man standing on the cargo just under the hatch; he pulled out a little bull's-eye lamp from his pocket and lighted it, and carefully extinguished the match. The long, misty beam of the magnified flame swept the interior like the revolving spoke of a wheel as the man slowly turned the lens about in a critical search of the place, himself being in blackness. The line of light broke on the casks behind which I crouched, and left me in deep shadow unperceived. After some minutes of this sort of examination, the man, came a little way forward and crouched down upon a bale or something of the sort directly abreast of the casks, through whose cant-lines I was peering. He opened the lamp and placed it beside him; the light was then full upon his figure.
