The point to which deconcentration is carried is not the same in all branches of the public service. Mr. Gladstone declared that the Chancellor of the Exchequer could not take as active a part as other ministers in the current business of his department;[186:2] while in the Foreign Office, on the other hand, it has been the tradition that the Secretary of State ought to see almost everything. No doubt this is in part due to the very nature of diplomatic relations, but there can also be no doubt that in the past it has been carried much too far. When Mr. Hammond was under-secretary for foreign affairs he insisted on making the first minute on all papers in the office.[186:3] A change has been made in this respect, and the practice brought more into accord with that which prevails in other departments;[186:4] but the Foreign Secretary is still expected to give his personal attention to a greater mass of detail than other ministers.[186:5] [Sidenote: Effect of the Procedure on the Power of Officials.] Now any subordinate who determines what questions he may decide himself, and what he will refer to his superiors, and who prepares the materials for a final judgment in the cases that he does refer, is certain to exert a great deal of influence. The permanent under-secretary, holding his position, as he does, for an indefinite period, devoting his whole time to the work, and becoming thoroughly familiar with the affairs of his department, can, no doubt, regulate the class of questions that shall be referred to him, and can acquire complete control over the administration. But the minister, who is usually unfamiliar with the department to which he is assigned, who remains at its head a comparatively short time, and whose attention is largely engrossed by the more exciting scenes enacted in the cabinet, in Parliament, and on the platform, must, unless gifted with extraordinary executive capacity, be to a considerable extent in the hands of his permanent subordinates.
