six o'clock in the evening
They sleep in hammocks , slung close to each other as on board ship , in two lines , with a passage down the centre . There is a wardsman to each ward . He is selected by the prisoners , and is generally a man of the worst character . He is supposed to keep order , but of course he never attempts to do so ; indeed , as he is locked up in the ward every night from six o'clock in the evening until sunrise , without light , it is possible that he might get maltreated did he make himself obnoxious . The barracks look upon the Barrack Square , which is filled with lounging prisoners . The windows of the hospital-ward also look upon Barrack Square , and the prisoners are in constant communication with the patients . The hospital is a low stone building , capable of containing about twenty men , and faces the beach .
