to inform the candidate that the latter examination will be
cancelled in the event of failure to pass the sight tests.

II. The Lantern Test.

(8.) A special lantern and a mirror have been provided for
this test. The lantern should be placed directly in front of
the mirror, so that the front part of the lantern is exactly ten
feet from the mirror. Care should be taken that the lantern
is properly placed, that is to say, the lights reflected in the
mirror must show clearly when viewed through the rectan-
gular aperture on the left of the lantern. The Examiner
should always satisfy himself that these conditions are ful-
filled before commencing the examination.

(9.) It is essential that a candidate should be kept in a room
which is either completely or partially darkened for at least a
quarter of an hour before he is required to undergo this test.

(10.) Before the examination commences the Examiner
must satisfy himself that the room in which it is conducted
is so darkened as to exclude all daylight.

(11.) The lantern supplied for the examination is so con-
structed as to allow one large or two small lights to be visible,
and is fitted with 12 glasses of three colours—red, white, and
green. At the commencement of the examination the Ex-
aminer should show to the candidate a series of lights through
the large aperture, and should require him to name the
colours as they appear to him. Care should be taken in
showing the white light to emphasize the fact that the light
is not a pure white. If a candidate makes a mistake of call-
ing this light “red,” a proper red light should be shown
immediately after, and the candidate’s attention directed to
the difference between the two.

After a series of lights through the large aperture has been
shown, the Examiner should make a complete circuit with
the two small apertures, requiring the candidate to name
the colours of each set of two lights from left to right. To
prevent any possibility of the order in which the lights are
arranged from being learnt, the Examiner should at least
twice in each circuit go back a varying number of colours.
He should keep a record of the number of the glass with
which he began the series and should take care to vary it
from time to time.

A record of any mistakes made with either the large aper-
ture or the two smaller apertures should be kept on Form
Exn. 17c in accordance with the instructions thereon.

(12.) As the lantern itself forms a test for colour ignorance,
the old colour ignorance test becomes unnecessary and should
be discontinued.

III. Success or Failure.

(13.) If a candidate with either the large aperture or the
two smaller apertures of the lantern mistakes red for green
or green for red, he should be considered to have “failed”
in colour vision.

(14.) If a candidate makes no mistakes in the wool test,
and if the only mistakes made by him with the lantern is to
call the white light “red,” and if after his attention has been
specially directed to the difference between the two he makes
no further mistake of this nature, he should be considered
to have passed in colour vision.

(15.) If a candidate makes any other mistake with the
lantern—i.e., if he calls white “red” repeatedly or red
“white” at all, or confuses green and white, or if he makes
any mistake whatever in the wool test, his case should be
reported to the Principal Examiner of Masters and Mates,
and he should be told that the decision as to whether any
further examination is necessary or not will be communi-
cated to him in due course. Pending the receipt of the
Principal Examiner’s instructions such a candidate should
only be allowed to proceed with the remainder of the ex-
amination for a certificate of competency on the express
understanding that the latter examination will be cancelled
in the event of failure in the sight tests.

IV. Further Examination and Appeals.

(16.) If in the cases covered by the preceding paragraph
the Principal Examiner decides that a further examination
is necessary, arrangements will be made for a special exami-
ation to be held, and the second-class travelling-expenses
necessarily incurred by a candidate in attending such an
examination will be paid by the Marine Department, together
with a subsistence allowance at a rate which will be notified
to the candidate, but which will not in any circumstances
exceed 10s. for each day necessarily occupied in attending the
examination. In these cases the above expenses will be
paid whatever may be the result of the final examination.

(17.) If, however, on the report of the local Examiner the
Principal Examiner decides that the nature of the mistakes
made shows conclusively that a candidate is so colour blind
as to be unfit to hold a certificate, the candidate shall be
considered to have failed.

In such cases, as well as in the cases covered by paragraph
13, the Marine Department will be prepared to allow a can-
didate who is dissatisfied with this decision to appeal for a
special examination, but the Marine Department will not
pay the travelling-expenses of any such candidate unless he
is reported by the special Examiners conducting the appeal
examination to have passed.

Appendix G is hereby revoked and the following substi-
tuted in lieu thereof:—

EXAMINATION IN CHART.

For all Grades where the Chart is used in Examination for
Foreign-going Certificates.

1. Using deviation [card] [curve]* No. , find the
   courses† to steer by compass from to ; also
   the distance on each course.

NOTE.—Alter course when and again when .
Answer.—1st Course . 1st Distance .
2nd ,, . 2nd ,, .
3rd ,, . 3rd ,, .
1st Deviation .
2nd ,, .
3rd ,, .

2. With the ship’s head on the above-named com-
   pass course bore by compass and
   bore by the same compass, find the ship’s position ;
   also the set and drift experienced since the course was set,
   ship steaming knots per hour and taking
   hours to reach this position.

Answer.—Latitude : . Longitude : .
Set : . Drift : .

3. With the ship’s head on above-named compass
   course bore by compass , and after con-
   tinuing on the same course (hours) (minutes), it
   bore , find the ship’s position, and her distance
   from , making due allowance for a (current) (tide)
   which set at the rate of knots per hour,
   ship steaming knots per hour.

Answer.—Latitude : . Longitude : .
Distance : .

• A candidate for an ordinary master’s certificate is expected to use
  either a card of deviations, or a curve of deviations on a Napier’s diagram,
  whichever the Examiner may put before him.

† These problems will be varied in the setting so as to include one,
two, three, or more courses, and the remaining problems will also be
varied so as to include all practical conditions.

For all Grades where the Chart is used in Examination for
Home-trade Ship Certificates, with the Exception mentioned
in Note below.*

[The candidate will be required to work out the following
questions on either a “true” or “magnetic” chart,†
whichever may be handed to him by the Examiner; and
also determine whether the chart is a “true” or “mag-
netic” one, and whether it is for the Northern or Southern
and Eastern or Western Hemisphere.]

1. Using deviation [card] [curve]‡ No. find the
   course to steer by compass from to ; also
   the distance.

Answer.—Magnetic course : .
Compass course : .
Distance : .
Variation : .
Deviation : .

2. With the ship’s head on the above-named compass
   course, a [point] [lighthouse] bore by compass
   and bore by the same compass. Find the
   ship’s position.

Answer.—Latitude : .
Longitude : .

3. With the ship’s head as above, a [point] [lighthouse]
   bore by compass , and after continuing on
   the same course miles it [or another point] bore
   . Find the position of the ship and her distance
   from at the time of taking the second bearing.

Answer.—Latitude : .
Longitude : .
Distance : .

• In examination for master of fishing-boats and cargo-vessels, and
  small sailing-vessels carrying passengers in restricted limits only,
  “magnetic” charts are used.

† The terms “true” and “magnetic” are used for the sake of brevity
and convenience to indicate charts that have compasses delineated upon
them showing the “true” or “magnetic” points of the compass respec-
tively.

For all Grades where the Chart is used.

4. What do you understand the small numbers to indicate
   that you see placed about the chart, and at what time of
   tide ?
