difference between the fee paid by him for the superior certificate and the fee payable for the inferior certificate may be placed to his credit.

May have to be re-examined for certificate of higher grade.

24. In such a case, when the applicant has by further service made up the time in which he was found to be short, he may be required, before he can receive the higher certificate, to be re-examined in all the subjects, unless the Marine Department sees fit to dispense with the re-examination.

Defaced certificates to be returned.

25. If any certificate of competency issued by the Marine Department which has been defaced so as to become illegible, or has been seriously injured by wear or tear, is presented to a Superintendent of Mercantile Marine in the course of duty, the same should at once be transmitted by the Superintendent to the Secretary of the Marine Department, together with the usual form of application for renewal of certificate, duly filled up, in order that a renewed certificate may be issued. This will be done free of charge in those cases where it is satisfactorily shown to the Marine Department that due care has been taken of the original. This power will have to be exercised with great discretion by the Superintendents of Mercantile Marine, so as not to interfere with any engagements for sea-service which the possessor of the injured certificate may have entered into.

Lower-grade certificates to be returned on higher-grade being issued.

26. When the holder of a certificate passes the examination for a certificate of a higher grade, his certificate of the lower grade will be withdrawn and retained by the Marine Department.
