ascertained.
Each average will then be multiplied by the number indicating the
relative weight of the subject or class, and the sum of the products
will be divided by the sum of the relative weights. The quotient will
determine the candidate's standing in the examination. Relative weight
will be assigned not merely to the special qualifications of the
candidates, but to their general aptitude, as shown in the course of
examination. Candidates will be examined during office hours, and in
no case will their examination be continued more than one day.

X. The board of examiners will prepare a list of the persons examined
in the order of their excellence, as proved by such examination,
beginning with the highest, and will then certify to the head of the
office the names standing at the head of such list, not exceeding
three. When more than one appointment is to be made, the vacancies
will be numbered, and the first three names will be certified for
the first vacancy, the remaining two and the fourth for the second
vacancy, the remaining two and the fifth for the third vacancy, and so
on for the whole number of vacancies; but if, after selecting one
of any three certified for appointment, the head of the office shall
object to another presentation of either of the remaining names, it
shall not be again certified.

XI. The examination papers of any candidate who shall have passed a
minimum standard of 75 per cent, but who shall fail to be appointed,
will, if requested by the candidate, be brought into competition with
those candidates who shall compete for vacancies of the same class
and nature occurring within one year: _Provided, however_, That the
candidate shall not have been specially objected to by the head of
the office under the last preceding regulation. No candidate who upon
examination has been marked below the minimum will be allowed to again
compete within one year from the date of such examination, unless for
admission to a lower group.

XII. All examination papers will be filed, and will at all times be
open to the inspection of those interested, under such restrictions as
may be imposed by the head of the office.

XIII. There shall be one examining board for all appointments
and promotions under these rules in the offices of the collector,
surveyor, and naval officer, which shall consist of the surveyor and
one representative to be nominated each by the collector and the
naval officer, and three alternate
