Section 4
SEC. 4. The Director-General of Posts is authorized to establish post-offices at any places in the Islands where in his judgment the interests of the public will be subserved by the establishment of such offices, and to fix the salaries of the postmasters on the basis, fixed in section three, of a percentage of the gross receipts of the post-offices, exclusive of the money-order business. To facilitate the establishment of post-offices at places where it is not practicable to secure suitable persons not in the public service for appointment as postmasters, the Director-General of Posts is authorized to appoint persons employed in other branches of the Civil Service, with the approval of the head of the department or departments in which such persons are employed, and subject to the approval of the Civil Governor. A person in the public service who may be thus appointed shall, in addition to his salary in the branch of the service in which he is employed, receive the compensation hereinbefore provided for such postal service.
