THE NEW ZEALAND GAZETTE.

73. Examination in Seamanship.—He must possess a thorough
    knowledge of the rule of the road as regards both steamers and sailing-
    vessels, their regulation lights, and fog and sound signals. He must
    be able to describe the signals of distress and the use and management
    of the rocket apparatus in the event of his vessel being stranded,
    and to have a knowledge of the ports in New Zealand where rocket
    apparatus for saving life is maintained. He must be able to mark
    and use the lead and log lines, to manage a ship's boat in a surf or in
    heavy weather, to bend, unbend, set, reef, take in, and furl sail, to
    know how to act for the safety of the vessel if caught in a sudden squall,
    and what action to take if a man falls overboard or if spars carry
    away; also any other questions of a like nature appertaining to the
    duties of the master of this class of vessel.

EXTRA CERTIFICATES.

Certificates as Extra Master.

74. Extra Master.—An extra master's certificate will entitle the
    holder to go to sea as master of any vessel, sailing or steam.
    The examination is voluntary, and intended for such persons as
    wish to prove their superior qualifications, and are desirous of having
    certificates of the highest grade granted by the Marine Department.
    The extra examination may take place when the applicant is
    qualified to go up for examination for an ordinary master's certificate,
    or at any time subsequent to his having passed the examination for
    that certificate. (See also para. 161.)

75. Examination in Navigation.—In addition to the work for
    the ordinary certificate the candidate must also be prepared to be
    examined in any of the following subjects, showing the construction
    of all the problems:
    (a.) To find the latitude or position from double altitudes of the
    sun or of a star.
    (b.) To determine, from simultaneous observations of two different
    stars, the position of the ship, and the true bearing of the
    stars, by Sumner's method. The candidate may either
    determine the four longitudes from the two assumed lati-
    tudes which will be given, or solve the question in any other
    way he may choose.
    (c.) To find the error of a chronometer from the altitude of the
    sun or of a star, observed with an artificial or with the
    natural horizon.
    (d.) To explain clearly in writing the principles of (1) great-circle
    sailing; (2) windward great-circle sailing; (3) composite
    great-circle sailing; and their advantages and disadvantages.
    (e.) To show approximately on a terrestrial globe the great-circle
    track and the distance from one given point to another;
    also the latitude and longitude of vertex; and the longitude
    from vertex; and to explain how the track can then be
    transferred to a Mercator's chart. Occasionally the candi-
    date will be required to lay the track down on a chart.
    (f.) To determine the initial great-circle course, and the distance,
    from one given position to another, the latitude and longi-
    tude of vertex, the longitude from vertex and the latitudes
    and longitudes through which the great circle will pass;
    laying the track, composite or otherwise, down on a Merca-
    tor's chart, and explaining briefly how the course and
    distance from one point to another on this track is then
    found. This problem may, subject to the decision of the
    Examiner, be solved either by calculation, or by any tables,
    graphic method, or great-circle chart known to and pre-
    ferred by the candidate, and it will usually be set so as to
    leave the choice of method to the candidate.
    (g.) To answer more advanced questions on plane and spherical
    trigonometry.
    (h.) To answer a paper on magnetism as relating to the compass.
    (i.) To construct a plan or chart on Mercator's principle and solve
    a given problem thereon.
    (j.) To answer a paper on naval architecture, including ship con-
    struction and stability.
    (k.) To answer a paper on general knowledge, including shipping
    business, imports and exports, astronomy, and general
    elementary science (except chemistry).
