surfaces of such concrete foundations
there must be coating of a standard
Portland mortar not less than one inch

beams may be painted with two coats OF
pure Portland cement liquid grout, OF
two coats of red lead and oil.
If, in case of continuous foundation
wall, isolated piers are to be built TO sup
port the superstI7icture where the nature
OF the ground and the character Of the
building make it necessary, inverted
arched walls walls shall be turned be-
tween the piers, az least II inches thick
and of the full width of the piers and rest
upon a continuous bed of concrete OF tim
Der of sufficient area of at least is inches
thick; or two footing courses Of dimen-
sion stone may be used, the bottom
course TO be laid crosswise, edge TO edge,
and the top course laid lengthwise end to
end, or on a footing Of steel beams bed
ded in concrete; OF one course of concrete
and one course of stone. The stone shall
not be less than 10 inches thick in each
course, and the concrete shall not be less
than Is inches thick and the area of the
| lower course shall be equal to the area
of the base course that would be required
under continuous wall, and the out
side pier shall be secured TO the second
pier with suitable Iron rods and plates
Every pier built of brick containing
less than nine superficial feet at the base
supporting any truss beam or girder, arch
column or Intel spanning and opening
over 10 feet, OF supporting a wall, shall
be capped with an iron plate of sufficient
strength and the full size of the pier. No
stone pier caps shall be used in buildings

stories.
In case It is desired 10 increase the
height of existing party walls or any
other walls, which are less in thickness
than required under the code, the same
shall be done by a lining of brick work
to form a combined thickness with the
old wall of not less than one-half brick
more than the thickness required for O
new wall corresponding with a tota
weight of the wall when so increased II

proper foundations. No lining shall b'
less than seven inches in thickness an,
all Innings shall be laid in cement mortal
and thoroughly anchored to the old bricl
