centre on the sole ground that reasonable facilities for holding such examination
do not exist at such centre. The decision of the Director in regard
to the holding of an examination at any centre shall be final.

13. The Director may, at his discretion, accept or decline to accept
    the application of any candidate or candidates.

14. The rooms and equipment of any technical school or manual-
    training centre shall be available for the purpose of the conduct of the

    Department may, however, pay such charges for heating, lighting, cleaning,
    material, or other service as may be deemed to be reasonable.

    stationery, &c., as may be necessary, shall be supplied by the Education
    Department, but candidates may be required to provide their own tools,
    drawing-instruments, or other equipment. The Education Department

    would be inflicted if the candidates themselves were required to do so.

16. The Director may make arrangements with any Technical School
    Board or any other body for the conduct of the examination, and of all
