During the month of March the prison was less crowded than at any subsequent time, and the average space of ground to each prisoner was only 98.7 feet, or less than seven square yards. The Federal prisoners were gathered from all parts of the Confederate States east of the Mississippi, and crowded into the confined space, until in the month of June, the average number of square feet of ground to each prisoner was only 33.2 or less than four square yards. These figures represent the condition of the stockade in a better light even than it really was; for a considerable breadth of land along the stream, flowing from west to east between the hills, was low and boggy, and was covered with the excrement of the men, and thus rendered wholly uninhabitable, and in fact useless for every purpose except that of defecation. The pines and other small trees and shrubs, which originally were scattered sparsely over these hills, were, in a short time, cut down and consumed by the prisoners for firewood, and no shade tree was left in the entire enclosure of the stockade. With their characteristic industry and ingenuity, the Federals constructed for themselves small huts and caves, and attempted to shield themselves from the rain and sun and night damps and dew. But few tents were distributed to the prisoners, and those were in most cases torn and rotten. In the location and arrangement of these tents and huts no order appears to have been followed; in fact, regular streets appear to be out of the question in so crowded an area; especially too, as large bodies of prisoners were from time to time added suddenly without any previous preparations. The irregular arrangement of the huts and imperfect shelters were very unfavorable for the maintenance of a proper system of police. The police and internal economy of the prison was left almost entirely in the hands of the prisoners themselves; the duties of the Confederate soldiers acting as guards being limited to the occupation of boxes or lookouts ranged around the stockade at regular intervals, and to the manning of the batteries at the angles of the prison. Even judicial matters pertaining to themselves, as the detection and punishment of such crimes as theft and murder appear to have been, in a great measure, abandoned to the prisoners.
