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 preferred by the candidate,
and it will usually be set so as to leave the choice of method
to the candidate.

g. Elementary mensuration, up to and including the measurement
of ship-shaped bodies; plane geometry, up to and including
the properties of the circle in relation to rectilinear figures;
plane and spherical trigonometry, up to and including the
solution of oblique-angled spherical triangles.

h. Magnetism as relating to the compass.

i. Construct a plan or chart on Mercator’s principle and solve a
given problem thereon.

j. Naval architecture, including ship construction and stability.

k. General knowledge, including shipping business, imports and
exports, astronomy, and general elementary science (except
chemistry).

He will be examined orally on the following subjects:—

l. Leading principles of the construction of the sextant and vernier,
mechanical logs, and sounding-machines.

m. Civil duties of a shipmaster, in which he will be expected to
show a more extensive knowledge than a candidate for an
ordinary master’s certificate.

In signalling he will be required to attain a minimum speed of
12 words a minute in semaphore, 10 words a minute in Morse lamp-
flashing, and 6 words a minute in Morse flag-waving.

The construction of the problems mentioned above, and of the
compass problems, must be shown as follows:—

i. A circle must be drawn representing the stereographic pro-
jection of the celestial concave on the plane of the earth’s
rational horizon—unless the problem can be better shown
otherwise—and a correct figure drawn in it, the magnitude
of the sides and angles being estimated approximately by eye.

ii. The sides and angles used in solving the problem must be
marked by distinguishing letters in the figure, and the
candidate must, over each fresh computation, write down
clearly what is given and what he is required to find, together
with the formula which he proposes to use.

iii. Opposite each quantity in the computation he must put the
letters denoting the part of the triangle which it represents,
writing “comp.” before the letters when the quantity is
the complement of that part of the triangle.

Candidates will not be required to enter into the mathematical
investigation of the rules and formulæ used in the solution of problems
involving oblique-angled spherical triangles, but credit will be given
to any candidate showing such knowledge. When, however, a problem
or part of a problem is solved by right-angled spherical trigonometry
the simple process of deducing the formula from the figure by Napier’s
rules for circular parts or other method must be shown.

Where a problem is solved by right-angled plane trigonometry the
simple process of deducing the formula from the figure for each of the
computations in it must be shown.

The rule for finding the latitude by meridian altitude must be
proved by the figure.

All sketches and drawings required in the paper on naval archi-
tecture should be neatly done on paper supplied by the Examiner.

78. Seamanship.—In addition to the qualifications required of
    an ordinary master, an extra master will be expected to give satis-
    factory answers to any questions in practical seamanship that the
    Examiner may ask.

EXTRA CERTIFICATES, STEAMSHIPS.

79. Extra Certificates, Steamships.—Extra certificates for steam-
    ships will also be issued, subject to the examination described below,
    to officers who can show the necessary service in steamships. The
    certificates will be marked “For steamships only,” and will only entitle
    the holders to go to sea as masters of steamships.

The examination is open to all who are qualified to sit for a certi-
ficate as master of a foreign-going steamship, or who have already
obtained that certificate. It is open also to candidates who have
failed, in the examination for an extra master’s certificate, to show
the requisite knowledge of the management of square-rigged sailing-
vessels. (See para. 23.)
