The whole question is complicated by the independent position that the City of London has been allowed to retain. From many points of view it would be advantageous to concentrate the entire police of the metropolis under one and the same administration, and to some amalgamation seems desirable for the sake of uniformity, if for no better reason; but regularity in our institutions is not in itself a great end to strive for, and it would be prodigal of labour to tinker with our going concerns merely to eliminate deviations from the normal. Against amalgamation much can be urged. The city wishes to retain its ancient privilege of policing itself, and as long as it maintains an efficient force entirely at its own expense, the government is not likely to interfere. The matter is largely one of finance. Under the existing arrangements, three-quarters of the total cost of the City police is raised in the city by a local police rate, and the remaining quarter is subscribed by the Corporation out of its revenue; if, however, the control was transferred to the Chief Commissioner of the Metropolitan Police, the city would only have to pay five-ninths of the total cost instead of the whole amount as at present--or putting it in another light, amalgamation would cost the Imperial Treasury more than fifty thousand pounds a year, which sum is the price that the city now pays for the privilege of managing its own police. A second objection to amalgamation is that the Justice Rooms at Mansion House and Guildhall are presided over by magistrates who are experts in commercial jurisdiction, and consequently the usefulness of these courts would be to some extent impaired if they became ordinary metropolitan police courts.
