QUALIFICATION FOR CERTIFICATES OF COMPE-
TENCY.

41. Qualification of Candidate for Second-class
    Engineer's Certificate. - A candidate for a Second-
    class Engineer's certificate must be twenty-one
    years of age.

Some misconception appears to exist as to the
qualifying services for Second-class Engineer
Certificates, since some candidates assume that
services in the capacities of fireman, stoker, or
donkeyman would be accepted. In order to
remove all doubt upon this point, applicants for
examination are informed that those services only
which afford opportunities of obtaining practical
experience as an engineer will be regarded; and
that service in the capacity of fireman, stoker,
donkeyman, or any other capacity than that of
engineer, will not be accepted as qualifying a
candidate to be examined for a Second-class
Engineer's Certificate.

(a.) He must have served an apprenticeship
to an engineer, and prove that during
the period of his apprenticeship he has
been employed on the making and re-
pairing of engines: Or, if he has not
served an apprenticeship, he must prove
that for not less than three years he has
been employed in some factory or work-
shop on the making or repairing of
engines. In either case he must also
have served eighteen months in a
home-trade steamer, or one year in a
foreign-going steamer, at sea, in the
engine-room; or
(b.) He must have served at least four years
at sea in the engine-room.
(c.) He must be able to give a description of
boilers, and the methods of staying them,
together with the use and management
of the different valves, cocks, pipes, and
connections.
(d.) He must understand how to correct
defects from accident, decay, &c., and
the means of repairing such defects.
(e.) He must understand the use of the
barometer, thermometer, hydrometer,
and salinometer.
(f.) He must state the causes, effects, and
usual remedies for incrustation and
corrosion.
(g.) He must be able to state how a tempo-
rary or permanent repair could be
effected in case of derangement of a
part of the machinery, or total break-
down.
(h.) He must write a legible hand, and
understand the first five rules of arith-
metic, and decimals.
(i.) He must be able to pass a creditable
examination as to the various construc-
tions of paddle and screw engines, com-
pound and otherwise, in general use;
as to the details of the different working
parts, external and internal, with the
use of each part.

42. Qualification of Candidate for First-class
    Engineer's Certificate. - A candidate for a First-
    class Engineer's Certificate must be twenty-two
    years of age.

In addition to the qualification required for a
second-class engineer, -

(a.) He must have served for eighteen
months in a home-trade steamer, or one
year in a foreign-going steamer, with a
Second-class Engineer's Certificate of
competency in the capacity of a second
engineer, and his name must have been
entered in the articles of agreement
accordingly.

By this it is intended that the same rule
shall be observed in the examination of
engineers as is observed in the examina-
tion of masters and mates-viz., that
before the certificate of a higher grade is
granted, certain service in the lower
grade must be performed.

The Examiner should therefore be satisfied
that applicants for the First-class Engi-
neer's Certificate have not only been in
possession of a Second-class Certificate
for eighteen months in a home-trade
steamer or one year in a foreign-going
steamer, but that they have actually
served not less than the periods men-
tioned in the engine-room with a Second-
class Certificate.

(b.) He must be able to make rough working
drawings of the different parts of the
engines and boilers.
(c.) He must also be able to take off and
calculate indicator diagrams.
(d.) He must be able to calculate safety-
valve pressures, and the strength of the
boiler.
(e.) He must be able to state the general
proportions borne by the principal parts
of the machinery to each other.
(f.) He must be able to explain the method
of testing and altering the setting of
the slide-valves, and of testing the fair-
ness of the paddle and screw-shafts, and
of adjusting them.
(g.) He must be conversant with surface
condensation, super-heating, and the
working of steam expansively.
(h.) His knowledge of arithmetic must in-
clude the mensuration of superficies and
solids, and the extraction of the square
root.

43. Engineer, Extra. - An extra first-class
    engineer's examination is voluntary, and is in-
    tended for such persons as wish to prove their
    superior qualifications, and are desirous of having
    certificates equivalent to those of the highest
    grade granted by the Board of Trade.

The extra examination may take place either at
the time the candidate goes up for, or after he has
passed for, a First-class Engineer's Certificate.

The candidate must be entitled to or possessed
of a First-class Engineer's Certificate of compe-
tency, and in addition to the qualifications re-
quired for a first-class engineer-

(a.) He must possess a thorough knowledge
of the construction and working of
marine engines and boilers in all their
parts, and be so far acquainted with the
elements of theoretical mechanics as to
