Very different considerations apply to the greater number of those who fill the subordinate places in the civil service. Their responsibility is to their superiors in official position. It is their duty to obey the legal instructions of those upon whom that authority is devolved, and their best public service consists in the discharge of their functions irrespective of partisan politics. Their duties are the same whatever party is in power and whatever policy prevails. As a consequence it follows that their tenure of office should not depend on the prevalence of any policy or the supremacy of any party, but should be determined by their capacity to serve the people most usefully quite irrespective of partisan interests. The same considerations that should govern the tenure should also prevail in the appointment, discipline, and removal of these subordinates. The authority of appointment and removal is not a perquisite, which may be used to aid a friend or reward a partisan, but is a trust, to be exercised in the public interest under all the sanctions which attend the obligation to apply the public funds only for public purposes. Every citizen has an equal right to the honor and profit of entering the public service of his country. The only just ground of discrimination is the measure of character and capacity he has to make that service most useful to the people. Except in cases where, upon just and recognized principles--as upon the theory of pensions--offices and promotions are bestowed as rewards for past services, their bestowal upon any theory which disregards personal merit is an act of injustice to the citizen, as well as a breach of that trust subject to which the appointing power is held. In the light of these principles it becomes of great importance to provide just and adequate means, especially for every Department and large administrative office, where personal discrimination on the part of its head is not practicable, for ascertaining those qualifications to which appointments and removals should have reference. To fail to provide such means is not only to deny the opportunity of ascertaining the facts upon which the most righteous claim to office depends, but of necessity to discourage all worthy aspirants by handing over appointments and removals to mere influence and favoritism. If it is the right of the worthiest claimant to gain the appointment and the interest of the people to bestow it upon him, it would seem clear that a wise and just method of ascertaining personal fitness for office must be an important and permanent function of every just and wise government. It has long since become impossible in the great offices for those having the duty of nomination and appointment to personally examine into the individual qualifications of more than a small proportion of those seeking office, and with the enlargement of the civil service that proportion must continue to become less.
