The examination of those about to become policemen extends over four weeks, and includes every detail of the multiplicity of duties, which ranges from the protection of the public from crime, down to tracking down truants from school, and the regulation of the books of the maid-servant class. The policeman who aspires to the rank of sergeant undergoes a still more rigorous examination, extending over twenty weeks of preparation, during which time he studies -- note this list, ye "young barbarians all at play," German, rhetoric, writing, arithmetic, common fractions, geography, history, especially the history of the House of Hohenzollern from the time of the margraves to the present time (!), political divisions of the earth, especially of Prussia and Germany, the essential features of the constitution of the Prussian Kingdom and German Empire, the organization and working of the various state authorities in Prussia and Germany, elementary methods of disinfection, common veterinary remedies, the police law as applicable to innumerable matters from the treatment of the drunk, blind, and lame, to evidences of murder, and the press law. The man who passes such an examination would be more than qualified to take a degree, at one of our minor colleges, if he knew English and the classics were not required, and could well afford to sniff disdainfully at the pelting shower of honorary degrees of Doctor of Divinity, which descend from the commencement platforms of our more girlish intellectual factories of orthodoxy. The cost of the police in Berlin in 1880 was 2,494,722 marks; in 1890, 3,007,879 marks; in 1900, 6,065,975 marks; and in 1910, 8,708,165 marks.
