whom reports are not made to the War Department direct. The Governor will make a similar report in the case of persons resident in the Colony when such persons apply through him to the Secretary of State for employment in the public service. 25. The claims of candidates for promotion will be considered in order of their seniority, but the selection will be mainly decided by regard to official qualifica- tions. Seniority in any Department is determined by the date of an officer's appointment to the particular grade or class in which he is serving. Seniority as between officers appointed on probation and subse- quently confirmed in their appointments is determined by the date of the probationary appointment. Except where otherwise provided at the time of appointment, seniority as between persons selected for appointment from outside the Colony is determined by the date at which they begin to draw any salary of their new office or, where two or more begin to draw such salary on the same date, by the date of the letter from the Colonial Office confirming the selection. 26. Appointments, provisional or permanent, of gentlemen who have been connected with the Governor as private secretaries, aides-de-camp, or otherwise are open to objection and must not be made without previous reference to the Secretary of State. B. Discipline. 27. Officers are required to discharge any duties upon which the Governor may think it desirable to employ them. 28. Salaried public officers whose remuneration is fixed on the assumption that their whole time is at the disposal of the Government are prohibited from angaging in trade, or employing themselves in any commercial or agricultural undertaking.
