“ Those who have not served in Her Ma. jesty's navy as engineers' boys, must be examined by the surgeon of the establishment as to their being of sound bodily constitution, and they must produce well authenti. cated certificates from the engineers in whose factories they have worked, of their being skilful workmen, of good disposition, and of good conduct in every particular, especially as regards sobriety.

APPOINTMENT. . “ Engineers are appointed by warrant from the Lords Commissioners of the Admiralty, or by commanders-in-chief on foreign stations, in vacancies occasioned by death in the same manner as other warrant officers of the navy are appointed.

“No person will be considered eligible for a second class engineer without having served at sea as an engineer, nor the first class without having served as chief engineer of a seagoing steam-vessel. In either case the can. didate must produce satisfactory testimonials of his efficiency and good conduct while thus serving at sea.

“An engineer, after having served three years in the third class, will be permitted, if he can produce good certificates from the commanders under whom he may have served, to present himselt in examination for the se. cond class, when a suitable opportunity shall offer, and, in like manner, after having served three years in the second class, he will be permitted to present himself for examination for the first class. If, however, on examination it shall appear to the examining officers that the qualifications of a candidate are such that a shorter period than three years may be sufficient to enable him to acquire the experience necessary for performing the duties of a higher class, a note thereof, with the reasons, will be made upon the passing certificate, which will render him eligible for examination and promotion in less than three years, if his subsequent conduct should appear to merit it.

• The first class engineer of ships in com. mission is to have the instruction of two engineers' boys, and to receive an allowance of 6d. per day for each.

" When there are three engineers' boys, the second class engineer is to instruct the junior boy of the three, and to receive the allowance of 6d. per day.

“When there are four engineers’ boys the senior second class engineer is to instruct the third boy; the junior second class engi. neer the fourth boy; and each is respectively to receive the allowance of 6d. per day for the instruction of the boy placed under him.

“ This allowance is to be granted only on the production of a certificate from the commanding officer under whose orders the engineers may be actually serving, that the boys have been duly instructed in conformity with the established regulations, and such certificate is never to be granted unless the superintendent of the dockyard, or the of. ficer in command of the vessel be thoroughly satisfied from personal observation that the intentions of these regulations have been strictly carried into effect.

Engineers when serving on board one of Her Majesty's steam-vessels within the tropics, while the steam is up, are to receive one-half the amount of the pay of the respective classes in addition, for which they may draw every six months whether they allot or not.

“ When engineers do not draw for their tropical pay, a certificate is to be granted to them, similar to that on the back of the bill for the adjustment of their claims to the said pay on their arrival in England.

Engineers of vessels in commission, when employed in repairing defects of other ves. sels than those in which they are serving, except in the home dockyards, Holyhead, the River Thames, Portsmouth, or Plymouth harbour, to be allowed extra pay as warrant officers in addition, according to the scale established by Her Majesty's regulationsnamely, 28. a-day.

The following rules shall be observed in regard to superannuations and pensions of the engineers of Her Majesty's fleet :

“ First.–That when engineers shall be found upon survey unfit for further service they shall be allowed 31. a-year for each year they shall have served as warrant-officers in ships in commission; and 11. a year for each year they shall have served as warrant-officers in ships in ordinary, or as supernumeraries in guard ships.

** 2nd. - That in cases in which the services of engineers shall appear to the Lords Commissioners of the Admiralty to be more than ordinarily meritorious, a further sum may be allowed to the said warrant-officers in addition to the pension allowed by art. 1, varying from 11. to 151, a-year, reference being had to the character of the officer, and the cause which may have rendered him unfit for service,

" 3rd.—1, that engineers who may lose two limbs in action ; 2, or who may receive wounds or injuries in action equal to the loss of two limbs ; 3, or who may receive injuries or hurts in the service, though not in action, equal to the loss of two limbs, shall be allowed pensions (as the Lords Commis. sioners of the Admiralty may deem proper),

“ Fourth Class.---Boys on entering the service as fourth class apprentices must not be less than 14 nor more than 17 years of age; they must be of good moral character and sound bodily constitution, and able to write and work a question in the rule of three.

“ Third Class.-At the expiration of their third year of service, provided their conduct has been good during that period, the boys will be considered eligible for removal to the third class if, on examination, they appear to have made themselves acquainted with the names and uses of every part of the engines, gauges, barometers, &c.

“ Second Class.-If boys, in the fourth year from their entrance into the service, be acquainted, through the instruction of the engineer under whom they may be placed, with the whole principle of the engine and boilers, with the use of all the various tools, and with the mode of effecting repairs, as far as they are performed on board ; if they be able to take off and replace any of the working parts; pack the slide-valves, pistons, piston rods, and stuffing-boxes ; if they understand the action and condensation of steam, the return of water into the boilers, the construction of all the pumps, and of the feeding and blowing off apparatus, safety valves, &c., and can chalk out roughly the outlines of the engines and wheels, and have become generally useful, they will be considered fit for removal to the second class, provided their conduct has been good.
