veyors in order to be used at the survey.
The surveyors report, rendered in duplicate, of the first
testing to which a boiler is submitted in this country, or after
having undergone extensive repairs or alteration, shall contain
an exact description of the boiler. The owners copy of the re-
port Of the said first survey, containing description of the boiler,
shall be produced at every subsequent survey.
Al the yearly examinations of stationary boilers, the owners
copy Of the last survey shall be accessible to the surveyor.
At the survey, the surveyors shall examine if all the regu.
lations enacted by this ordinance, concerning the boiler, have
been complied with, and subject the boiler to a TEST OF PRES
SURE by pumping in water, by which test it is shown if he boil
er under a pressure Of Is Of The steam pressure to which it is to
be subjected during use exhibits any essential leak Or any con,
siderable change Of form which might involve danger in the use Of
the boiler under the pressure of steam stated by the owner or
the party, using it. The test pressure ought however never to be
If on anyof the stages of the test of pressure, the boiler has
shown any noticeable leak or suffered such change Of form that
admissible, the surveyors are still, on demand to that effect, an.
thorNed to examine how great a pressure the boiler is capable of
resisting without showing any noticeable leak and without sui,
tering any noticeable or lasting change of form.
The boiler must only be used at a pressure Of steam not erceed-

mum OF allowed steam pressure is also set down at , Of the
pressure under which the boiler has been tested.
When the allowed maximum OF the steam pressure on the
boiler has been determined, and the safety valves and their
weighing have been adjusted in accordance Herewith, the point
Oh adjustment thus determined is marked, as well on the safety
valves as on their weighing apparatus, with stamps indicating,
ON the valve ITSELF the diameter of escape, i'll Danish lines ('',
on the levers, their full length, in Danish inches r'b and, on the
weights which constitute the loading of the valves, their weight,

al pieces, each separate piece is stamped with Its weight.
If a safety valve is weighted by springs in tension, the stop
per which prevents undue tension is stamped with indication of
With the consent of the owner, the surveyors are, as excep.
ton, authorized to test a boiler without the safety valve having
Deen fitted OF, provided that they ascertain by calculation that
the weighing of the valve is such that the allowed maximum of
pressure cannot be exceeded, and subsequently indicate that
such is the case by means of the stamping above enacted.
d. Concerning the attendance Of steam boilers subject to
public CONTROL
Upon and around the Boiler everything must be kept clear,
clean and orderly the DQmper Of the chimney must always be
orderly.

firing commences the water IS at least up to the level of the
waterline of the boiler. At least once every day the engine
driver must see that the stop cocks OF the glass are i'll order
by opening the blow cock, ana, at the same Ume, with proper
caution, opening and closing alternately the two connecting
cocks. If any of the cocks is choked, it must be cleared at
once any leak found must be repaired as soon as possible.
If the glass breaks, it must be replaced, at all events
at the first stOppage of any duration.
q The float must be tried frequently, particularly when firing
commences, to ascertain that 1T moves freely
The WATER LEVEL of the boiler must not be allowed to sink
below the waterline marked outside the boiler, which MARX shall
always be kept plainly indicated. II owing to some cause or
other, f. j., neglectfnlness on the part OF the engine driver or a
sudden, large consumption Of steam, the water SINKS considera-
bly, lower and, particularly, so low as not to be indicated by the
water gauges or by the gauge cocks, and thus tis to be feared
that some part of the surface IL not III contact with wafer, the
boiler, ifconnected with one or more other boilers, must be dis
connected from such other boiler or boilers; and, this done,
the fire must be raked out at once, the damper ana the furnace
door opened, and the boiler left quiet to cool. Under no clrcum-
stances must water be put into the boler before me coollng

If any part of the hue has become red-hot, the boiler must
not be used before it has been ascertalned BY careful examlna-
