RULE XIII.

1.  The date of the reception of all regular applications for the classified departmental service shall be entered of record by the Commission, and of all other regular applications by the proper examining boards of the district or office for which they are made; and applicants, when in excess of the number that can be examined at a single examination, shall, subject to the needs of apportionment, be notified to appear in their order on the respective records.  But any applicants in the several States and Territories for appointment in the classified departmental service may be notified to appear for examination at any place at which an examination is to be held, whether in any State or Territory or in Washington, which shall be deemed most convenient for them.

2.  The Compassion is authorized, in aid of the apportionment among the States and Territories, to hold examinations at places convenient for applicants from different States and Territories, or for those examination districts which it may designate and which the President shall approve.

RULE XVI.

1.  Whenever any officer having the power of appointment or employment shall so request, there shall be certified to him by the Commission or the proper examining board four names for the vacancy specified, to be taken from those graded highest on the proper register of those in his branch of the service and remaining eligible, regard being had to the apportionment of appointments to States and Territories; and from the said four a selection shall be made for the vacancy.

2.  These certifications for the service at Washington shall be made in such order as to apportion, as nearly as may be practicable, the original appointments thereto among the States and Territories and the District of Columbia upon the basis of population as ascertained at the last preceding census.

3.  In case the request for any such certification or any law or regulation shall call for those of either sex, the four highest of that sex shall be certified; otherwise sex shall be disregarded in such certification.

4.  No person upon any register shall be certified more than four times to the same officer in the customs or postal service or more than twice to any Department at Washington, unless upon request of the appointing officer; nor shall anyone remain eligible more than one year upon any register.  No person while remaining eligible on any register shall be admitted to a new examination, and no person having failed upon any examination shall within six months thereafter be admitted to another examination without the consent of the Commission; but these restrictions shall not extend to examinations under clause 5 of Rule VII.
