Some officers OF the United States
army in the war with Mexico noticed ia
a chapel of that country a rarely beau
tiful window made OF thin translucent
pieces of richly colored stone. One OF
the officers brought home some pieces
Of the stone apd left 1t with a jeweler of
this city to be dressed and shaped, but
icing ordered to the frontier he went
away without receiving the finished
material back from the ieweler. This
was the first OF the stone seen in this
country and il attracted no great atten-
ION. About thirty wears later cohsid-
cradle quantities Of the material were
exhibited as Mexican onyx at the Cen
Iennial exposition Al Philadelphia.
The Mexican onyx OF that day was
greatly admired. but the price was SO
high, about ten times what it now is,
that the material was looked upon as n
semi-precious stone. Ever since 1876
the material has become cheaper and
cheaper, until now it is used in large
quantities, though only in expensive
structures. One of the earliest build-
ings to contain a large quantity of Mex
lean onyx was a luxurious London hotel
built not many years ago. Its staircase

Several of the Mexican states send ONYX
to u, but the largest deposits are found
near Tecali, in the state of Pueblo. 1t
was used by the ancient Mexicans for
mass. idols and other small objects.
and some Of the modern Mexicans, find
ing these works of their ancestors adj
mired by travellers, turn out like objects
from the stone and sell them at good
prices. William Cooper of Esperanza
found about seven years ago in a VOL
cano OF Mexico a deposit that is now
called mosaic agate. 1t is 4 peculiarly
beautiful sort of Mexican onyx. in which

is also found in Iowa.
Mexican onyx is easily worked, and
has been used not only for building
purposes, but for ornamental household
articles, lamp standards, table tops,
nantes and other articles large and
small. Some of the earlier articles OF
the sort have considerably decreased in
value since the price of the onyx came
down and it has been so lavishly used
In building. 1t is, of course. not suited
for statuary because its ~variegated coli
ors would give the subject a motley APP
pearance that would not be beautiful,
but absurd. The material is too valua-
BILE to be used much in places where it
would be exposed to the weather. Its
use has become so extended in this city
that it is new largely imported by n few
marble dealers. Ii hardly gives in the
crude state the promise OF its finished
beauty. and scraps apd fragments OF
the crude stone are now wasted that
would have been eagerly preserved
were its price what it was nineteen
years ago. 1t may be doubted whether
any church Of the United States has
been decorated as the little Mexican
chapel OF nearly fifty wears ago.
An extensive dealer In Mexican onyx
and other marbles says that the stone is
less used than it was ten years ago. so
he thinks, because other and cheaper
stones, notably African marble, are
more beautiful. There have been with
in a few years several notable speculate
i've i~mportations of Mexican onyx. In
some Of these cases the importers, fad
ing the sale unexpectedly slow. were
unable to pay the duties, and the guam
tity in port broke the price. Mexican
onyx sells in the rough at So to $50 q
cable foot. Large pieces fetch more
than their proportional price. The
saving into slabs adds about 50 a cubic
foot 10 the price. and the further cut
ting, lifting, and polishing greatly in
creases the value of the stone. There
is often a loss of 40 per cent of material
in preparing it for wainscoting. so that
the finished product fetches as high as
&c a foot. When one inch thick spe-
cially beautiful specimens fetch even
more, and it is possible to run up the
cost of a building decorated with spe.
