THE CIVIL SERVICE Jl striking implrovements in public Departments have come from people new to the work, approaching it with a fresh mind. Florence Nightingale instructed the War Office in the obvious principle that when hospital stores are at hand* -and needed, they should be used—there is no need to wait till next month for permission to "open them. Common sense, it is argued, acts as a corrective to routine. There is a real distinction between the work of a political chief and that of a Civil Servant. The former decides what the objects of Government policy -are; the latter advises how they can be attained. The former must be ready to move from one Depart- ment to another, as the death or retirement of members of his party create vacancies; the latter is usually engaged on one type of work throughout. The former inust leave his work when his party is defeated; the latter is a permanent official.1 This distinction, however, must not be over-emphasised. No one can say what the Government ought to do unless he has some idea how it can be done. Ministers, therefore, do make an attempt to understand the technicalities of their Departments: among^the leading figures of any party there may be one who has devoted special attention to education, another to foreign affairs, and so on—if their party is victorious it is clear which Departments they will control. In every subject there are certain fundamental rules which anyone of good intelligence can grasp, without making the subject his life-work.
