1. Every regular application must be supported by proper certificates
of good moral character, health, and physical and mental capacity for
doing the public work, the certificates to be in such form and number
as the regulations of the Commission shall provide; but no certificate
will be received which is inconsistent with the tenth section of the
civil-service act.
2. No one shall be entitled to be examined for admission to the
classified postal service if under 16 or over 35 years of age, or
to the classified customs service or to the classified departmental
service if under 18 or over 45 years of age; but no one shall be
examined for appointment to any place in the classified customs
service, except that of clerk or messenger, who is under 21 years
of age; but these limitations of age shall not apply to persons
honorably discharged from the military or naval service of the
country who are otherwise duly qualified.
