Under the circumstances related in my last number, it will readily be inferred that sleep was out of the question. The only alternative was to sit or lie down and meditate upon the next change which might befal us. There was but little disposition for merriment at such a time and place; yet there was one man, named John Young, but called by his companions 'Old John Young,' who in despite of empty stomach and aching limbs, amused himself and annoyed all others by singing a line of one and a verse of another, of all the old songs he could recollect from his earliest boyhood; dispensing his croaking melody with such untiring zeal as to keep the most weary awake had they been inclined to sleep. At break of day we began to try to move about, and gradually straighten ourselves, which was something of an effort, stiffened and benumbed as we were with remaining in our wet clothing so many hours. We had now an opportunity of examining our habitation. It was a building of about four hundred feet long, by seventy-five or eighty wide, three stories high, and built of stone, with massive doors and strongly-grated windows, the floors being of stone or cement, and perfectly fire-proof. Each floor formed one entire room, except being divided by five rows of posts running the whole length of the building, by which the prisoners slung their hammocks. The prisoners were divided off in 'messes' or families of six or eight, each occupying room sufficient to sit around one of their chests, which usually served as a mess-table. One row or tier of these messes were ranged next to the walls on each side, and two rows down the centre, back to back, as it were, leaving two avenues, or thoroughfares, the whole length of the building. The entire arrangement resembled the stalls in a stable, more than any thing else I can compare it to. There were seven of these prisons, all of about the same size and construction, one of which was not occupied. The whole was enclosed in a circular wall of about twenty feet high, and covering a space of from eight to ten acres of ground. This was divided in three parts by a wall similar to the outside one. The centre yard was occupied by No. 7, allotted to the colored prisoners, and the other two yards had three prisons in each. On the outside wall were platforms and sentry-boxes at short distances, for the guards. About fifteen feet within that wall was a high iron railing. In front of the main entrance was a large square, used for drilling soldiers and other purposes, and twice a week as a market for the country people; and on each side of this were the barracks and hospital, and in front of these were the officers' quarters. This dépôt was situated upon a hill, surrounded by a vast common of many miles in extent, without a bush or tree to relieve the dreary waste; and from its elevated position it was generally shrouded by clouds, rendering it chilly and uncomfortable the greater part of the year.
