over and above the atmospheric pressure, at which the boiler is
to be used. The description is placed into the hands of the sur
VeyoTS III 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
an exact description of the boiler. The owners copy of the re-
port of the said first survey, containing description of the boiler;
AT 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-
HtionS enacted by this ordinance, concerning the boiler, have
been complied with, and subject the boiler to a TEST OF PRES
SURE by pumping i'll water, by which test is shown If the boil

With the consent of the owner, the surveyors are, as excep-

such is the case by means of the stamping above enacted.
ID. Concerning the attendance OF steam OOH@S SUBJECT to
public control
Upon and around the Boiler everything must be keptclear,
clean and orderly the Damper Of the chimney must always be
orderly.
The GAUGE Cocks and the WATER GAUGES must always
be kept in a clean and serviceablc state.
a. The gdugec0cks must be examined several times every day,
but especially every time firing commences, II they choke,
they must be ceanSed forthwith.
While the boiler is being used the lowermost cock shall
always show water; the middle Geek also as a rule, water;
and the upper cock steam.
b The sstnjc of the water guage must be consulted free
quentIy and it must, particularly, be observed that when
firing commences the water IS ut 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 III order

caution, opening and clos ing alternately the two connect
cocks. If any of the cocks is choked, it must be cleared at

If the glass breads, it must be replaced at all events
at the first St0ppage OF any duration.
cl The float must be tried frequently, particularly "heh nHhg
commences, to ascertain that it moves freely.

The WATER 1EvEI, of the boiler must not be allowed to sink
below the waterline marked outside the boiler, which marx shall
always be kept plainly indicated. If owing to some cause or

boiler. if connected with one or more other boilers, must be dis
connected from such other boiler or boilers; and, TINS done,
the fire must be raked out at once, the damper and the furnace
door opened, and the boiler left quiet to cool. Under no clrcum-
stances must water be uut into the boiler before the cooling
down of the boiler and the settingwall has taken place:

not be used before it has been ascertalned by carelui eXahlha-
