possible) with a hammer, that the boilers are free from danger from
corrosion or other defects, are well made of good material, the openings
for the passage of water and steam, respectively, and all pipes and tubes
exposed to heat are of proper dimensions, and free from obstruction; that
the flues and tubes, if any, are circular in form, the furnaces in proper
shape, and the fire line of the furnaces is at least two inches below the
minimum water line of the boilers; and shall also satisfy himself thait the
safety valves are of suitable dimensions, sufficient in number and well
arranged, and that the weights are properly adjusted so as to allow no
greater pressure in the boiler than the amount prescribed in the certificate
of inspection; that there is a sufficient number of gauge-cocks, a steam
gauge, a coupling cock in suitable position for attaching the hydrostatic
test, that means for blowing out are provided, so as to thoroughly remove
the mud and sediment from all parts of the boilers when they are under
the pressure of steam, and that fusible metals are properly inserted so as
to fuse by the heat of the furnaces when the water in the boilers shall fall
below the prescribed limits, and that adequate and certain provision is
made for an ample supply of water at all times; when the inspection is
completed and the inspector approves the boiler, he shall make and sub-
scribe a certificate of inspection, stating the condition of the boiler, the
number of years or months it has been in use, and the pressure of steam
allowed; and no greater pressure than that allowed by the certificate shall
be applied to such boiler. In limiting pressure, whenever the boiler under
test will, with safety, bear the same, the limit desired by the owner shall
be the one certified; and such certificate of inspection shall be framed
under glass, and kept in some conspicuous place on the premises where
said boiler referred to is used; and if the inspector shall deliver or cause
to be delivered to the owner or renter of any boiler a certificate of inspec-
tion without having first subjected the said boiler to the tests as, herein
provided, he shall forfeit his bond, and upon conviction shall be removed
from office by the Governor.

578. In addition to the annual inspection, it shall be the duty of the
inspector to examine all boilers within the limits of their respective dis-
tricts once at least in every three months and if deemed necessary, apply
the hydrostatic test; and if on such examination the inspector shall find
evidence of deterioration in strength, he shall revoke the certificate and
issue another, assigning a lower rate of pressure; and if the defect be
of such character as to make the boiler dangerous, the inspector shall
notify the owner or renter in writing, stating in the notice what is re-
quired, and order the use of the boiler discontinued until the necessary
repairs are made; and if he considers it beyond repair, he shall condemn
it; and if the owner or renter shall refuse or neglect to comply with the
requirements of the inspector, and shall, contrary thereto, and while the
same remains unreversed, use the boiler, he shall be liable to a penalty
of not less than one hundred dollars for each day such boiler is used, and
