EXTRA CERTIFICATES.

Certificates as Extra Master.

76. 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.

77. Navigation.—In addition to the work for an ordinary master’s certificate the candidate must be prepared to be examined in any of the following subjects, showing the construction of all the problems :—
    a. Find the latitude or position from double altitudes of the sun or of a star.
    b. Determine, from simultaneous observations of two different stars, the position of the ship and the true bearing of the stars. The candidate may either determine the four longitudes from two assumed latitudes, or solve the question in any other way he may choose.

    e. 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 explain how the track can then be transferred to a Mercator’s chart. Occasionally the candidate will be required to lay the track down on a chart.
    f. Determine the initial great-circle course, and the distance from one given position to another, the latitude and longitude 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 Mercator’s chart, and explaining briefly how the course and distance
