A NEW METHOD OF BUILDING.

A new plan for making buildings fire-prOof
has just been devised II is as applicable to buildings
already completed to IL consists OF apply
ing plaster and similar compositions to the beams ana
framework of buildings, thereby giving them fire.
proof coating The plaster il put on by the use OF mod
instead of by the trowe method and can be applied to
building fronts ceilings. floors, the upright supports
which sustain Mansard roofs.
To cover the surface of wall. vertical mold false
wall is placed at the requisite distance from the surface
to be coated The plaster then poured into the
between the false and real walls, until 1t Ia entirely
filled The outer surface OF the coating when the false
wall is removed, will be an exact impression OF the
mold II is claimed that the finest wood graning as
well as holdings and carvingsscan thus be cheapy null

cred in sections greater esser extent, until the
work is complete.
In the OF ceilings, a false ceiling is supported or
suspended at suitable distance under the beams OF
latbs, according to the thickness OF plaster desired
The surface OF the pendant ceiling may be ornamented
plain The plaster poured in from above upon the
pendant ceiling The plaster will adhere TO beams
and laths while the application of glyeerine prevents
II from adherng to the false ceiling which, Taen % 'nH
plaster becomes dry Is removed lt Is claimed that al
the Mansard roofs which are now supported by mbers
and light frame work can be made perfectly safe by the
application OF this plaster.
Col Andrew Derrom of Paterson N j.. is the inventor
of the material and his idea OF French roofs that they
should be made OF light frame work and then ed s4d
with tho plaster referred TO. He claims that they
would thus become sOllu ana enduring; that Woou
work-ntcnded only to give shape to the concrete and
tighten -wOuld be thoroughly protected from fire by
the covering, and that there being hollow spaces OF
archambers between the surface ID would be impossible
for fire TO start from the inside while the outside of
the roof would he covered with slate. He proposes To
make the interior work of buildings Of the same
material Partitions be cast in a mold AZ their
proper places and I've finished off in four or five
hours whereas 1t would require six weeks TO do the
pastering in the ordinary way. They are OF course
solid and may be shaped al little cost into panels cor
nces and holdings. When finished they are perfectly
hard, and will be unaffected by heat cold. He claims
that the best freprO0f material known is composed OF
the preparations of brick mortar and cement and that
his preparation, with the additional nOncOnduotOr
plaster OF Paris, will make absolute reproof surface
He has also patented plan for uniting with cement
numbers of bricks into blocks and for putting the build
lngs together into sections The blocks may be made
the thickness Of ordinary wall and set in their places
blocks OF marble arranged. IL Is stated tna he
greater part of the work be done In Winter by boys
the arches doors and windows being made ready for
their positions and the whole building being prepared
before it is put together. Sections of sewers column
piers arches and grained work be made, there
by facilitating the work and greatly reducing the cost
The inventor states that he will be willing to erect
building according to his plan, allow fires to be knded
every part OF the house. and glaran ee that II VIII not
burn down. and be willing to suffer the full penalty OF
any failure that may result His Office In Paterson Is
finished of in this STYLE and is said to present fine ana
substantial appearance. He claims that II is hreprOOf,
and iny ties the public to examine into the matter
