~ THE minds Of most people mar
bic and granite, two stones Of
widely different characteristics,
III are inherently symbolical Of beau.
ty, strength and permanonce. They
preserve the tradition Of something
stable and enduring. Mans use OF
marble and granite has, Of course,
dated from the days Of antiquity; IN
deed, of all componcnts Of the Carth 5
crust no two, perhaps, have been
more universally pressed into ;he serV-
fee Of construction and decoration.
The worlds Yield Of the finer classes
Of marble proceeds from many coun'
tries, Italy, France, Belgium, Norway
Sweden and America being especially
prolific IN deposits.
Apart from the British Isles, where,
in particular, the gray Aberdeen and
red Petnrhead varieties are justly
famed, granite occurs in Sweden, the
Tyrol, Italy, Sardinia, North America
and other districts
Qualities of Marble and Granite.
In chemical composition marble is
essentially calcium.carbonate or car
! )nate Of lime. As consequence, the
stone Is very sensitive TO tho action
OF chemical agents present In the at
| mosphere On the other hand while
marble IL in this way more rapidly at
tackled than many other stones, It's
power TO resist the mechanical agents
OF weathering, which are generally the
most destructive, makes it a compare
lively durable substance. The great
variety Of colors shown by marble is
due mainly to the presence OF cOmpan-
ion minerals, Iron, when present in
the ferrous state, produces color vary
Ing from light to dark green; manga
nese and cobalt involve pinkish hues.
Accessory minerals, in short, give rise
to an almost endless association and
blending of colors, shades, veins and
/ patterns.
Granite is a crystalllncg ag.
gregate Of quartz, felspar and mica,
and comprises all varieties Of texture.
! Generally It is the constituent felspar
which gives the ruddy or the gray ap.
pearance diiferentiatiug the rock. Tn.
like marble, granite cannot be split NJ
with saws, and hence the expense and
labor Of Quarrying and preparing the
latter material for building and other
! purposes is relatively much greater.
According TO the state goologist OF
Georgia, probably no building stone in
the United States has IN recent years
met with such universal favor and
gwen greater satisfaction than Geor
gia marble, 1t is, however curious
to learn that, Notwithstanding the
enormous quantity Of native marble
capable Of being quarried, and the
| large number of undCveloped deposits
which ne United States as u whole
possesses, considerable supplies of the
material are imported (mostly from
italy, for statuary purposes and in
terror decoration. The growth Of tn,
use OF Georgia marble for publ,
buildings in America is, however, pro
ceeding on satisfactory lines, and II,
merits are becoming generally known
