can be made. Such temporary appointment shall in no case continue longer
than ninety days, and shall expire by limitation at the end of that
time. No person shall serve longer than ninety days in any one year
under such temporary appointment or appointments, and in any event only

thereto has been separated from a position in said district to which he
was temporarily appointed under the provisions of this section.

14. Whenever a temporary appointment shall be made through certification
from the eligible registers of the Commission in the manner provided in
these rules, such temporary appointment shall in no case continue longer

date of said requisition has through no delinquency or misconduct been
separated from a classified position at the date of said requisition and
in that Department or office and that branch of the service in which

these rules, in the opinion of the Commission, an examination involving
essential tests different from or higher than those involved in the
