There are about three hundred mounted police in the force, and these, as a whole, come under the control of the department, although at ordinary times they are attached to divisions.

They used to be attached to the outer divisions, but it was found that they were too far away when an emergency arose, for, after all, the mounted man is of most use in controlling unruly crowds. So now they are with the inner divisions, within easy reach of the most crowded thoroughfares when needed.

All the men in this branch of the service have been thoroughly trained in horsemanship, and those who have seen them at work on their adroit horses, keeping back a mass of pushing, struggling people, or dexterously dispersing a threatening crowd, know their worth as maintainers of order.

Both the Executive and Statistical Departments are concerned with reports which are the basis of all discipline and organisation in the Metropolitan Police. The first—"The Morning Report"—is compiled by the superintendents of divisions, and passed and commented upon by the Chief Constables in charge of districts.

This is London's bill of criminal health. It shows what has happened beyond the ordinary over seven hundred square miles in the preceding twenty-four hours. A murder, a riot, a robbery, a fire, a street collision—all things are recorded. Every police station, it should be said, keeps an "Occurrence Book" and it is from this that the reports are compiled.

Then there is the "Morning Report of Crime." This is largely the work of the divisional detective-inspectors. Every crime for which a person can be indicted is included here, and an elaborate report of the steps that have been taken. Comments are made upon this by both the Chief Constable of the district and the Assistant-Commissioner of the C.I.D.—commendations, reprimands, suggestions.

The third report is the "Morning State," which deals with matters of internal administration of the force itself—numbers available, disciplinary matters, affairs of health.

All these reports ultimately reach the departments for record and for the transmission of orders.
