If men are not to be appointed by favoritism, wise or unwise, honest or dishonest, they must be appointed in some automatic way, which generally means by competitive examination. The easiest kind of competitive examination is an examination in writing. This is entirely appropriate for certain classes of work, for lawyers, stenographers, typewriters, clerks, mathematicians, and assistants in an astronomical observatory, for instance. It is utterly inappropriate for carpenters, detectives, and mounted cattle inspectors along the Rio Grande--to instance three types of employment as to which I had to do battle to prevent well-meaning bureaucrats from insisting on written competitive entrance examinations. It would be quite possible to hold a very good competitive examination for mounted cattle inspectors by means of practical tests in brand reading and shooting with rifle and revolver, in riding "mean" horses and in roping and throwing steers. I did my best to have examinations of this kind instituted, but my proposal was of precisely the type which most shocks the routine official mind, and I was never able to get it put into practical effect. The important point, and the point most often forgotten by zealous Civil Service Reformers, was to remember that the routine competitive examination was merely a means to an end. It did not always produce ideal results. But it was normally better than a system of appointments for spoils purposes; it sometimes worked out very well indeed; and in most big governmental offices it not only gave satisfactory results, but was the only system under which good results could be obtained. For instance, when I was Police Commissioner we appointed some two thousand policemen at one time. It was utterly impossible for the Commissioners each to examine personally the six or eight thousand applicants. Therefore they had to be appointed either on the recommendation of outsiders or else by written competitive examination. The latter method--the one we adopted--was infinitely preferable. We held a rigid physical and moral pass examination, and then, among those who passed, we held a written competitive examination, requiring only the knowledge that any good primary common school education would meet--that is, a test of ordinary intelligence and simple mental training. Occasionally a man who would have been a good officer failed, and occasionally a man who turned out to be a bad officer passed; but, as a rule, the men with intelligence sufficient to enable them to answer the questions were of a type very distinctly above that of those who failed.
