of fire CRATE and of heating surface, how much of heating surface
lies above the water line, and the maximum steam pressure,
to be used. The description is placed into the hands of the sur
veyors in order to be used at the survey.
The surveyors report, rendered III duplicate, of the first
testing to which a boiler is submitted i'll this country, or after
an exact description of the boiler. The owners copy of the re-
port of the said first survey, containing description of the boiler,
Shall hc produced at every Subsequent survey.
a. 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 the boil
er under a pressure of 3 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
under 100 lbs.
If on anyof the stages of the test of pressure, the boiler has
the use of the boiler under the stated pressure is considered in
admissible, the surveyors are still, on demand to that effect, au-
thorIed TO examine how great a pressure me boiler is capaoleot
resisting without showing any noticeable leak and without suf-
ferlng any noticeable or lasting change OF form.
ing. IS Of the pressure mder pMch it has bee" tested aud found
SUFFICIENTLY StaUnch and tight
In the case of a boiler tested in a foreign country, the maxi,
mum OF allowed steam pressure is also set down at SIS 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 s"fetyYalYes ana their
weighting have been adjusted in accordance Herewith, the point
OF adjustment thus determined is marked, as well on the safety
valves as ON their w%eghting apparatus, with stamps indicating,
on the valve itself the diameter of escape, in Danish lines ('''h
on the levers, their full length, in Danish inches Fb and, on the
weights which constitute the loading OF the valves, their weight,
in Danish pounds. If the weighing Of the valves consists ofsever-
al pieces, each separate piece is stamped with its weight.
fla safety valve is weighted by springs in tension, the stop
per which prevents undue tension is stamped with indication OF
It's length, in Danish lines PHh
With the consent OF the owner, the surveyors are, as excep-
ton, authorized to test a boiler without the safety valve having
been fitted on, 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.

Upon and around the Boiler everything must be kept clear,
clean and orderly the DGmD6f OF the CHIMNEY must Always De
orderly.
The GAUGE Cocks and the WATER GAUGES must always
be kept i'll a clean and seTVicpable state.
a. The g~augocOcES must be examined several times every day,
but especially every time firing commences, II they choke,
they must be cleanScd forthwith.
While the boiler is being used the IowermOst cock shall
always show water; the middle Geek also as a rule, water;
and the upper cock steam.
b The glaSS-tnbe OF the watergauGo must " consulted ire
quentIy; and it must, particularly, be observed that when
firing commences the water IS at least up to the lever OF the
waterliue of the boiler. At least once every day the engine
driver must see that the stop cocks OF the glass are III order
byopening the blow cock, and, at the same time, 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.
G The float must be tried frequently, particularly "neu nrInB
commences, to ascertain that it moves freely

The WATER 1EvE1. of the boiler must not be allowed to sinh
below the waterline marked outside the boiler, which mark shall
always be Kept plainly indicated. If owing to some cause or
other, f. l., neglectfulneSS on the part OF the engine urNei OF d
sudden, large consumption Of steam, the water SlnfS eonsldera-
bly, lower and, particularly, so low as not to DC lhdlcated Dy me
water gauges or by the gauge cocks, and thus It is to be feared
that some part of the surface is not i'll contact with water, the
boiler, ifc0nnected with one or more other boilers, must o us
connected from such other boiler OF boilers; ana, ms zone
the fire must be raEed out at once, the damper ana the furnace
door opened, and the boiler left quiet to cool; Under no clrGtn-
stances must water be put into the boiler before inc coollng
If any part of the fue has become red-hot, the boiler must
not be used before it has been ascertained by careful examlna-
