production of imitation stone and
marbles, cement is entering into the
new field of palace and temple COM

Finely yeined, granulated, white,
coloFed and Yari-colored mable sur
faces, faithfully true In detail TO the
marbles initiated and capable of taking
high finishes, are found among the
wares OF the modern cement factory.
Parian marbles can be made In Penn
sylyania as well as quarfied on the
Isle Of Paros,
IL the production of artificial sand
stones, GRANTEES, marbles and mosaic
work. the whole technique of the ce-
ment worker is tested. He not only
has to mix durable stone, but has to
incorporate coloring stuffs, veinings,
marble patterns and granulated sur
fac :, all of which must be able to
wlths and the action of water, heat,
frost, acid and salts. The polished
marble surfaces must wear as we'll as
natural stone. The, roughened sur
faces must be more resistant than the
qdariied sandstone.
Granite limitations are finding wide
employment in this country and still
more widespread use in Europe They
are used chiefly In the construction of
large buildings and homes and as side
walk slabs, monuments and grave
stones. Cement GRANTEES are close
copies of natural stone. They have
high supporting, strength are water
proof. an can be produced far more
cheaply.i
Muea of the beauty of granite is
owing to the sparkle of its quartz
or ,lerl n
corns which enter into its compost
tion. The quartz crystals are some
times White sometimes greenish, often
bright as water prisms and, again like

quartz and the mica must be retained in
the cement granite, which, as are the
natural GRANTEES. are produced In three
eolorE--in white, red and green.
The great body of the artificial gran
