EXAMINATION OF MASTERS AND MATES FOR CERTIFICATES OF COMPETENCY Under "The Merchant Shipping Act, 1854," AND VOLUNTARY EXAMINATION IN STEAM. UNDER the provisions of the "Merchant Shipping Act, 1854," no "Foreign-going ship"* or "Home Trade Passenger Ship" can obtain a clearance or transire, or legally proceed to sea, from any port in the United Kingdom unless the Master thereof, and in the case of a Foreign-going Ship the First and Second Mates, or Only Mate (as the case may be), and in the case of a "Home Trade Passenger Ship" the First or Only Mate (as the case may be), have obtained and possess valid Certificates, either of Competency or Service, appropriate to their several stations in such ship, or of a higher grade; and no such ship, if of one hundred tons burden or upwards, can legally proceed to sea unless at least one officer besides the Master has obtained and possesses a valid Certificate, appropriate to the grade of Only Mate therein, or to a higher grade; and every person who having been engaged to serve as Master, or as First or Second Mate or Only Mate of any "Foreign-going Ship," or as Master or First or Only Mate of a "Home Trade Passenger Ship," goes to sea as such Master or Mate without being at the time entitled to and possessed of such a Certificate as the Act requires, or who employs any person as Master, or First, Second, or Only Mate of any "Foreign-going Ship," or as Master or First or Only Mate of any "Home Trade Passenger Ship," without ascertaining that he is at the time entitled to and possessed of such Certificate, for each offence incurs a penalty not exceeding Fifty Pounds. 2. Every Certificate of Competency for a “Foreign-going Ship" is to be deemed to be of a higher grade than the corresponding Certificate for a " Home Trade Passenger Ship," and entitles the lawful holder to go to sea in the corresponding grade in such last-mentioned Ship; but no Certificate for a "Home Trade Passenger Ship" entitles the holder to go to sea as Master or Mate of a "Foreign-going Ship." 3. Certificates of Competency will be granted to those persons who pass the requisite examinations, and otherwise comply with the requisite conditions. For this purpose examiners have been appointed, and arrangements have been made for holding examinations at the ports and upon the days mentioned in the Table marked A, page 13. The days for examination are so arranged for general convenience, that a candidate wishing to proceed to sea, and missing the day at his own port, may proceed to another port where an examination is coming forward. 4. Candidates for examination must give in their names to the Local Marine Board if the place where they intend to be examined is a port where there is a Local Marine Board, on or before the day of examination (except in the case of Londont and Liverpool), and must By a "Foreign-going Ship" is meant one which is bound to some place out of the United Kingdom beyond the limits included between the River Elbe and Brest; and by a "Home Trade Passenger Ship" is meant any Home Trade Ship employed in carrying Passengers; and it is to be observed that Foreign Steam Ships when employed in carrying Passangers between places in the United Kingdom are subject to all the provisions of the Act, as regard Cerlicates of Masters, Mates, and Engineers, to which British Steam Ships are subject: s. 291 of the Merchant Shipping Act, 1854, and s. 5 of the Merchant Shipping Act, &c., Amendment Act, 1862. + At London applications for examination must be made on Fridays from 10 till 4, and on Saturdays from 10 till 3. At Liverpool applications for examination must be made on Tuesdays, Wednesdays, Thursdays, and Saturdays, during office hours. B conform to any regulations in this respect which may be laid down by the Local Marine Board; and if this be not done, delay may be occasioned. 5. Testimonials of character, and of sobriety, experience, ability, and good conduct on board of ship will be required of all applicants, and without producing them no person will be examined. As such testimonials may have to be forwarded to the office of the RegistrarGeneral of Seamen in London for verification before any certificates can be granted, it is desirable that candidates should lodge them as early as possible. The testimonials of servitude of Foreigners and of British Seamen serving in foreign vessels, which cannot be verified by the Registrar-General of Seamen, must be confirmed either by the consul of the country to which the ship in which the candidate served belonged, or by some other recognized official anthority of that country, or by the testimony of some other credible person on the spot having personal knowledge of the facts required to be established. Upon application to the Superintendent of the Mercantile Marine Office candidates will be supplied with a form (Exn, 2), which they will be required to fill up and lodge with their testimonials in the hands of the examiners. 6. Services which cannot be verified by the proper Entries in the Articles of the Ships in which the Candidates have served cannot be counted. Thus,-for instance, a Man will state his Service to have been as Second or Only Mate, and to support this assertion will produce a Certificate of Discharge or Employment by the Master stating that he served as Mate, when on reference to the Articles it appears that he has actually been rated as boatswain; the service in such a case will not be regarded as having been in the capacity of Mate. Whenever a Man has, from any cause, been regularly promoted on a vacancy in the course of the Voyage from the rank for which he first shipped, and such promotion, with the ground on which it has been made, is properly entered in the Articles and in the Official Log Book, he will of course receive credit for his service in the higher grade for the period subsequent to his promotion. 7. The examinations will commence early in the forenoon on the days mentioned in page 13, and will be continued from day to day until all the candidates whose names appear upon the Superintendent's list on the day of examination are examined. 8. Where the Local Marine Board are in every respect satisfied with the testimonials of a candidate, service in the coasting trade may be allowed to count as service, in order to qualify him for examination for a Certificate of Competency for Foreign-going Ships as a Mate, and two years' service as Mate in the coasting trade may be allowed to count as service for a Master's Certificate, provided the candidate's name has been entered as Mate on the Coasting Articles, and provided he has already passed an examination.

He must be able to work a day's work complete, including the bearings and distance of the port he is bound to, by Mercator's method; to correct the sun's declination for longitude, and find his latitude by meridian altitude of the sun; and to work such other easy problems of a like nature as may be put to him. He must understand the use of the sextant, and be able to observe with it, and read off the arc. (See List A, page 9.) In Seamanship.-He must give satisfactory answers as to the rigging and unrigging of ships, stowing of holds, &c.; must understand the measurement of the log-line, glass, and lead-line; be conversant with the rule of the road, as regards both steamers and sailing vessels, and the lights and fog signals carried by them, and will also be examined as to his acquaintance with "the Commercial Code of Signals for the use of all Nations." 10.
