The Scottish jury consists of fifteen men, and the verdict of a majority is required. They may decline on the evidence to express an opinion on the prisoner's guilt, but instead may find the charge not proven. This is the most practical provision for giving a prisoner the benefit of any doubt that exists in their minds after hearing the evidence. Whatever the verdict may be, the prisoner, having been once tried, cannot again be charged with the same offence. It is difficult to conceive any system under which a prisoner charged with crime could be more fairly treated; and if in the minor Courts offenders received the same consideration, the number sent to prison would be greatly diminished and the ranks of the habitual offender would fail to receive so many recruits. CHAPTER II THE PRISON SYSTEM Centralisation--The constitution of the Prison Commission-- Parliamentary control--The Commissioners--The rules--The visiting committee--The governor and the matron--The chaplain--The medical officer--The staff. Before the year 1877 all the Scottish prisons, with the exception of the Penitentiary at Perth, were under the control and management of the local authorities. One result was that there were many standards of treatment, and Parliament decided that as the prevailing methods were unsatisfactory the treatment of prisoners and the management of prisons should be vested in a central Board. The changes made by the Prison Commission have been many, and the prison of to-day is widely different from that of forty years ago; but before attributing all improvements to the new system it is fair to take into account the progress made in local administration during that time. The true comparison is not between the prison of forty years ago and that of to-day, but between the prison and the local institutions of to-day. Central management is likely to result in uniformity of routine and treatment in all prisons; but it is questionable whether that is a gain. It may tend to more economical administration if the test is one of expenditure of money, but it makes experiment in the way of reform very difficult. Not only are no two men alike, but no two districts are alike; and methods of dealing with people belonging to one part of Scotland are not necessarily the best to apply to the inhabitants of another part. It is not a good thing to bring prisoners from outlying districts to centres; there is always a danger of their remaining there after their liberation and obtaining introductions that will not be likely to help them except in the way of wrongdoing. The large institution may cost less money, but it can never have such intimate supervision as the small one.
