The Medical Officer must be a registered practitioner, and it is his duty to look after the health of the staff and of the prisoners. Of all the officials he has the freest hand, for it has not so far been practicable to direct the treatment of the sick from a central office; but his very freedom--such as it is--may lead him into trouble should he pay regard to differences of temperament among prisoners and go beyond a consideration of merely physical signs. If he confine his energies to carrying out the rules he need never fear death from work or worry. He may hope to become a highly respectable fossil and have a place in the esteem of everyone to whom he has caused no trouble. He can do much to help prisoners, not by indulging them, but by humanising the place to some extent and setting the tone. He need not be a better man than his colleagues, but he is less a part of the working machine, and that should make a difference in his attitude. He is not concerned with discipline, for the sick are free of it, so that in a sense it is his business to interfere with discipline. His work is to do the prisoners good in a way they can understand; and he has even an advantage over the Chaplain, whom they also recognise as a humanising influence, for men are usually a good deal more anxious about their bodies than about their souls. The Governor may be a better man than either the Doctor or the Chaplain, but his position as the head of a system that the prisoners do not regard as directed to their aid handicaps his influence on them. At one time the clerical staff of the prisons was composed of clerks, but now men who join as warders are promoted to clerkships, serving part of the day in the prison and part in the office. All applicants for warderships have to pass a series of examinations and to serve on probation for twelve months before being finally admitted to the service. A rigid enquiry is made as to their antecedents; their health forms the subject of a careful enquiry; and they have to pass an examination in general education. After all this they receive a salary which is not large, to put it mildly. It is a steady job, and therefore sought after by those who prefer to take a small salary with security of tenure to risking the rough-and-tumble of industrial life. Female warders are paid better than men, as women's wages go. Compared with the work done by them in other institutions they are well off, but there is not a rush for vacancies. Both male and female warders in Scottish prisons will compare favourably with any other body of officials; and the prevailing spirit shown by them towards prisoners is kindly and human.
