Outside the block of cells is an airing-yard, which consists of a space round which two narrow paved walks run. On these the prisoners take their exercise, each walking for an hour daily for the benefit of his health; separated by a space from the prisoner in front and the prisoner behind him, and watched by a warder lest any conversation or sign of recognition takes place between him and his fellows. The elderly or physically defective prisoners walk round the inner ring, where the pace is slower. Some of the female prisoners undergo a course of instruction in Swedish drill. Their opinion is expressed in the name by which the exercise is known. It is called the "Daft hour," and they enjoy it. As to its usefulness from an industrial standpoint the less said the better. It does no harm and it is a pleasant break in the day. In short, the prisoners are better employed in going through the drill than in doing something worse. CHAPTER IV VARIATIONS IN ROUTINE The sick--Prison hospitals--The removal of the sick to outside hospitals--The wisdom of this course--The essential difference between a prison and other public institutions--The treatment of refractory prisoners--The folly of assuming that rules are more sacred than persons--The position of the medical officer in relation to the prisoner--The danger of divided responsibility--The untried prisoner--His privileges--Civil prisoners--Imprisonment for contempt of court--The convict--Short and long sentences. The system makes no provision for individual differences between prisoners and takes no account of the past training which has made them what they are, but it recognises physical differences. It is the duty of the Medical Officer to see that no one is overtaxed or underfed or insufficiently clothed, and to attend to any sickness that occurs. If a prisoner is insane he is removed to a lunatic asylum. If he is ill he is put under treatment. In the majority of cases the prison hospitals are simply larger and better-lit cells. They are free from anything but the roughest imitation of modern hospital appliances; but as there is no occasion for the treatment in them of prisoners suffering from acute serious illness, they are sufficient for the needs they are required to meet. What is required for the treatment of such as are sick is not so much stone and lime as flesh and blood. Not new hospitals, but trained nurses.
