Section 15
SEC. 15. No census clerk, interpreter, or messenger shall enter upon his duties until he has taken and subscribed to the following oath: "I, ...................................................................., do solemnly swear that I recognize and accept the supreme authority of the United States of America, and will maintain true faith and allegiance thereto, and that will honestly and faithfully perform such duties in connection with the census of the Philippines as may be intrusted to me. So help me God." This oath, when executed, shall be forwarded through the census supervisor of the proper province to the Director of the Census and be duly filed in his office. No supervisor, supervisor's clerk, enumerator, or special agent shall be accompanied by, or assisted in the performance of his duties by, any person not duly appointed as an officer or employee of the Philippine Census, and to whom the oath or affirmation has not been duly administered. All appointees and employees provided for in this Act shall be appointed or employed solely with reference to their fitness to perform the duties of the position to which they may be appointed, and wherever practicable, shall be natives of the Philippine Islands, and such employees and appointees shall not be subject to the provisions of the Civil Service Act, Numbered Five, and the amendments thereto: Provided, however, That the Director of the Census is authorized to call upon the Civil Service Board in cases in which he deems it practicable and useful to certify an eligible list for any position to be filled by appointment in the Bureau, and it shall then be the duty of the Civil Service Board to make proper certifications as in other cases.
