29. Service performed on rivers, no matter of what size, and service performed within smooth- or partially-smooth-water limits will not be accepted.
    Where any doubt whatever exists on this point, the candidate must be required to produce a certificate from the master or owner of the vessel in which the service was performed, before the service can be accepted.
30. In the case of service on board excursion-steamers, only such service as can be proved to have been performed actually at sea can be accepted.
31. Service in auxiliary-screw whaling-ships and other vessels with auxiliary steam-power, which use their screws only in calms or during light winds, is considered as service performed in sailing-vessels.
32. Service in a lower grade than first or only mate in the home or coasting trade will not be recognised as officer's service towards qualifying a candidate for examination for a foreign-trade certificate.
33. Service as additional or auxiliary first mate or as auxiliary second mate (when a third mate is carried) in large foreign-going vessels will count as first mate's or second mate's service, as the case may be, provided that the candidate was entered on the articles in one of these capacities, and that he was during the whole time claimed in charge of a watch or watches.
34. When service "in charge of a watch" in either the foreign or home trade is specified in the regulations, the candidate will have to prove that during the whole of the time claimed he had the regular charge of a watch or watches, which, if in the foreign trade, must amount to not less than eight hours of each twenty-four hours of service. It must be distinctly understood that occasional service in charge of a watch will not be accepted as mate's service under the regulations.
    Great care must be exercised by the Examiners, &c., in regard to such service, and unless the candidate produces a clear and satisfactory certificate, specially setting forth the above facts, from the master or owner of the vessel in which the service was performed, it must not be accepted.
35. The term "pilot" in these regulations (see pars. 57 and 83) means a pilot who is employed in general pilotage, and holds a first-class pilot's certificate from some competent authority authorising him to pilot vessels outside harbour and partially-smooth-water limits.
36. Candidates whose services have been in capacities other than apprentice, midshipman, ordinary seaman, or able seaman—e.g., cook (when it is performed in small vessels, where cooking is only a part of a man's duty), carpenter, or sailmaker—will be required to satisfy the Marine Department that they have during the whole time claimed performed deck duties in addition to their own particular work, and that they have a good knowledge of seamanship. These facts may possibly be proved by the production of satisfactory certificates from the masters with whom the applicant has served; but such service will only be accepted as equivalent to two-thirds of the same time served as ordinary deck-hand. Failing satisfactory evidence, the applicant will be required to perform additional service in the capacity of seaman. Service as cook (under other conditions than the above) or as steward will not be accepted.
37. Half the time served on board a training-ship will be allowed to count as service at sea up to a limit of one year (i.e., no length of service will be allowed to count as more than one year at sea), provided that the candidate can produce a certificate from the committee that he has conducted himself creditably, and passed a good examination in seamanship, so far as it is practised in the training-ship, as well as in other matters, down to the time of his leaving the ship; but this service will not be regarded as equivalent to service in square-rigged vessels.
38. The whole of the time served under indentures of apprenticeship (unless the same are cancelled through some fault of the candidate) will be accepted as actual sea service under the regulations, provided that the applicant has served at sea four-fifths of the time claimed as apprentice (i.e., that he has not spent more than one-fifth of the time claimed in home ports), and provided also that his indentures are indorsed by the owner or master to whom he has been bound to the effect that he has performed his service faithfully during the time he remained apprentice. In cases where an apprentice may be qualified for examination before the expiration of his indentures (or for any other satisfactory reason) a letter from the owner or master will be accepted in place of this indorsement.
    In the event of the candidate being short of the required four-fifths of his apprentice's time, he will be required to show sufficient additional sea service, either as seaman or junior officer, to make up the four-fifths of the time claimed as apprentice.
39. The whole of the time served as midshipman in the mercantile marine will be accepted subject to the same conditions as those laid down for apprentices, provided the candidate has been bound by indentures during the time claimed as midshipman, but not otherwise.

SERVICE IN THE ROYAL NAVY AND ROYAL NAVAL RESERVE.
40. Officers of the Royal Navy are at liberty to apply for certificates of service and to be examined for certificates of competency in the mercantile marine, but the Lords Commissioners of the Admiralty have directed that the applications of officers on the active list should be made through their commanding officers.
41. Officers of the Royal Navy desirous of being examined for certificates of competency in the mercantile marine will be required to prove the following service, and if the officer wishes to obtain an ordinary certificate he must prove that at least twelve months of this required period was served under sail alone.
42. For second mate: A candidate must produce satisfactory evidence of four years' service at sea, or that he has attained the rank of acting sub-lieutenant.
43. For only mate: A candidate must prove five years' service at sea.
44. For first mate or master: A candidate must show that he has attained the rank of sub-lieutenant.
45. Officers of the Royal Naval Reserve who perform sea service on board Her Majesty's ships in the capacity of lieutenant or sub-lieutenant will be allowed to count such service as if it had been performed on foreign-going merchant ships; and the service will rank according to the certificate of competency held by the candidate at the time.
46. If accompanied by a good report, half the time spent in drill in the Royal Naval Reserve, and in harbour ships of the Royal or colonial navies, will be allowed to count as sea service, subject to the limit that no such service must amount to more than one-fourth of the time required for the particular grade of certificate applied for.

FORM-VISION, COLOUR-VISION, AND COLOUR-IGNORANCE Tests.
47. The following are the rules relating to the form-vision and colour tests:—
(1.) Examinations for form-vision, colour-vision, and colour-ignorance are open to all persons serving or intending to serve in the mercantile marine, and all such persons are recommended to take the earliest opportunity of ascertaining by means of these examinations whether their vision is such as to qualify them for service in that profession.
(2.) The examination consists of three parts: (a) Form-vision test (see Note A); (b) colour-vision test (see Note B); (c) colour-ignorance test (see Note C).
No candidate will be examined in the colour-vision test until he has passed the form-vision test, or in the colour-ignorance test until he has passed the colour-vision test.
(3.) Any person serving or intending to serve in the mercantile marine, if desirous of undergoing the form-vision, colour-vision, and colour-ignorance tests only, must make application to the Superintendent of a Mercantile Marine Office, and must pay a fee of 2s. 6d.
This fee will be payable on each occasion upon which a candidate is examined in form, vision, and colours only.
(4.) Every candidate for a certificate of competency who is not already in possession of such a certificate will be required to pass the three tests mentioned in Rule 2 before he can proceed to the examination in navigation and seamanship for the certificate which he desires to obtain, even though he may have passed the tests on some previous occasion.
(5.) Every candidate who is already in possession of a certificate of competency, and who desires to obtain a certificate of a higher grade, will be required to pass the three tests mentioned in Rule 2 before he can proceed to the examination in navigation and seamanship for the certificate of a higher grade.
That is to say, no candidate will be permitted to proceed with the examination in navigation and seamanship for a higher certificate if he fails to pass the three tests.
(6.) If a candidate fails to pass any of the three tests, a note of the fact of his having done so will be written across the face of the certificate which he already possesses before the certificate is returned to him.
(7.) If a candidate who undergoes the form-vision, colour-vision, and colour-ignorance tests only (see Rule 3) is in possession of a certificate of competency, he must hand in his certificate before the examination commences; and if he fails to pass any of the three tests a statement of his failure will be written on the certificate before it is returned to him.
