The Criminal Investigation Department is under Mr. Basil Thompson, a comparatively young man who came from the Prison Commission to succeed Sir Melville Macnaghten, and who has successfully experimented with some new ideas to make the path of the criminal more difficult. Mr. Frank Elliott, who was formerly at the Home Office, holds sway over the Public Carriage Office; and the Hon. F. T. Bigham, a barrister—and a son of Lord Mersey, who gained his experience as a Chief Constable of the Criminal Investigation Department—deals with and investigates the innumerable complaints and enquiries that would occur even in a police force manned by archangels. Mr. Bigham is also the Central Authority under the terms of the international agreement for the suppression of the white slave traffic.

There are six Chief Constables, mostly ex-military officers. One of these assists in the administration of the Criminal Investigation Department, the remainder control districts of four or five adjoining divisions. To adopt a military simile, they may be compared to major-generals in command of brigades, with each division representing a battalion, and the superintendents, colonels.

Only once in the whole history of the Metropolitan Police has a man risen from the ranks to the post of Chief Constable, though many, like Mr. Gentle at Brighton, and Mr. Williams at Cardiff, have become the heads of important provincial forces. The post of superintendent in London is at least equivalent in its responsibilities to the average chief-constableship of the provinces. There are metropolitan section sergeants who have as many men under their control as some chief constables of small boroughs.

The unit of the Metropolitan Police is a division which averages about a thousand men. Each is under a superintendent, with a chief-inspector as second in command. Thereafter the ranks run:

Uniform Branch.Detective Branch.
Sub-divisional Inspectors{ Divisional Detective-Inspectors.
{ Central Detective-Inspectors.
Inspectors Detective-Inspectors
Station-Sergeants First Class Detective Sergeants.
Section-Sergeants Second Class Detective-Sergeants
Constables (reserve) Third Class Detective-Sergeants
Constables (according to seniority) Detective-Patrols

These are distributed among close on two hundred police stations in the metropolis, and in twenty-two divisions. Some are detailed for the special work with which London as London has nothing to do. Thus there are: the King's Household Police; divisions guarding the dockyards and military stations at Woolwich, Portsmouth, Devonport, Chatham, and Pembroke; detachments on special duty at the Admiralty and War Office and the Houses of Parliament and Government Departments; and men specially employed, as at the Royal Academy, the Army and Navy Stores, and so on. In all, there are 1,932 men so engaged.[1] Their services are charged for by the Receiver, and the cost does not fall upon the ratepayers.

Scotland Yard is run on the lines of a big business. To the intimate observer it is strangely similar in many of its aspects to a great newspaper office, with its diverse and highly specialised duties all tending to one common end. The headquarters staff is a big one. There are superintendents in charge of the departments, men whom no emergency can ruffle—calm, methodical and alert, ready to act in the time one can make a telephone call.

There are McCarthy, of the Central Criminal Investigation Department; Quinn, of the Special Branch which concerns itself with political offences and the care of Royalty; Bassom, of the Public Carriage Department; Gooding, of the Peel House Training School; West and White, of the Executive and Statistical Departments.

Nothing but fine, careful organisation could weld together these multitudinous departments with their myriad duties. It is an organisation more difficult to handle than that of any army in the field. The public takes it all for granted until something goes wrong, some weak link in the chain fails. Then there is trouble.
