sential to safety Of life, when such vessels are
employed in the carriage of passengers to be call
ed the Inspector Of Hulls; the other Of whom, from
his knowledge and experience Of the duties Of an
engineer employed in navigating vessels by steam,
and also in the construction and use of boilers and
Fthe machinery and appurtenances Herewith con
nected, shall be able to form a reliable opinion OF
the quality of the material, the strength, form,
workmanship, and suitableness of such boilers and
machinery to be employed in the carriage of pas
sengcrs without hazard to life from imperfections
in the material, workmanship, or arrangement OF
any part of such apparatus for steamng, to be call
ed the Inspector of Boilers and these two persons
thus designated, if approved by the Secretary OF
the Treasury, shall be from the time OF such desig
nation inspectors, empowered and required to per.
form the duties herein specified, to wit:
First Upon application in writing by the mas-
ter owner they shall. once in every year at least
carefully inspect the hull Of each steamer belong
ing to their respective districts and employed in
the carriage Of passengers, and shall satisfy them.
selves that every such vessel so submitted to their
inspection is OF structure suitable for the service
in which she is to be employed, has suitable
accommodations for her crew and passengers, and
is in q condition to warrant the belief that she may
be used in navigation q steamer with safety to
life, and that all the requirements OF law in regard
to fires, boats pumps, hose, lifepreservers, floats,
and other things faithfully complied with; and
if they deem it expedient they may direct the YES
sci TO be put in motion, and may adopt any other
suitable means to test her efficiency and that of
her equipment.
Second. They shall also inspect the boilers of
such steamers before the same shall be used, and
once in every year thereafter, subjectihg them
to hydrostatic pressure, the limit to which, not
exceeding one hundred and sixty five pounds to
the square inch for high pressure boilers, may be
prescribed by the owner or the master, and shall
satisfy themselves by examination and expert
mental trials that the boilers we'll made of good
and suitable materially that the openings for the
passage of water and steam respectively, and all
pipes and tubes exposed to heat, are OF proper d.

line of the furnace is below the prescribed water
line Of the boilers; and that such boilers and the
machinery, and the appurtenances may be safely

satisfy themselves that the safety. valves are Of

arranged, and in good working order, Zone

eating such vessel j that there Is a suitable num-

height of the water and the pressure of the steam
that in or upon the outside flue OF each outside
high-pressure boiler there is placed in suitable
manner alleged metals, fusible by the heat Of the
boiler when raised to the highest working pressure
allowed, and that in upon the top Of the aues Of
all other high pressure boilers in the steamer such
alleged metals are placed aforesaid, fusing at
ten pounds greater pressure than said metals on
the outside boilers, thereby in each case letting
steam escape; and that adequate and certain pro
vision is made for ample supply of water to feed
the boilers at all times, whether such vessel is in
motion not; 90 that in highpressure boilers the
water shall not be less than four inches above the
hue Provided, hotpeper, in steamers hereafter sup
piled with new high pressure boilers if the alloy
fuses on the outer boilers at pressure of ten
pounds exceeding the working pressure allowed,
and at twenty pounds above said pres on the
inner boilers, it shall be Sufficient compliance
with this act.
Third. That In subj1Utins to the hydrostatic
test aforesaid boilers called and usually known
under the designation of high pressure boilers, the
inspectors shall assume one hundred and ten
pounds to the square inch as the maximum pres
sure allowable as working power for a new boil
er forty two inches in diameter, made Of inspected
iron plates at least one fourth OF an inch thick, In
the best manner, and of the quality herein requir-
ed, nd shall rate the working power OF all high
pressure boilers whether of greater or less diam
eter, old or new according to their strength COM
pared with this standard and in all the test
applied shall exceed the working power allowed
in the ratio of one hundred and sixty five to one
hundred and ten, and no high pressure boilers
hereafter made shall be rated above this standard;
and in subecng to the test aforesaid that class OF
boilers usually designated and known as low pres
sure boilers, the said inspectors shall allow a
working power of each new boiler pressure of
only three iourths the number of pounds to the
square inch to which it shall have been subjected
by the hydrostatic test and found to be sufficient
therefor using the water in such tests at tempe
nature not exceeding sixty degrees Fahrenheit but
should such inspectors be Of the opinion that said
boiler, by Of its construction MATERIAL will
not safely allow 60 high a working pressure, they
may, for reasons to be stated specifically in their
certificate fix the working pressure OF said boiler
at less than three-fourths of said test pressure;
and no low pressure boiler hereafter made shall
be rated IN it's working pressure above the aforc-
said standard; and provided that the same rules
shall be observed in regard to boilers heretofore
made, unless the proportion between such boilers
and the cylinders, or some other cause, renders II
manifest that its application would be unjust, in
which cases the inspectors may depart from these
rules, if it can be done with safety but in no case
shall the working pressure allowed exceed the by
drostatic test; and no valve, under any circum-
stances, shall be loaded or managed in any way
to subject boiler to greater pressure than the
amount allowed by the inspectors, nor shall any
boiler or pipe be approved which is made in whole
in part bad material is un safe in its form,
or dangerous from defective workmanship, age,
use, or any other cause.
Fourth. That when the inspection in detail is
completed, and the inspectors approve of the yes
sci and her equipment throughout, they shall make
and subscribe certificate to the collector of the
district, substantially as follows:
