Ell granite over the entrance TO the Ameri.

New York shows how the whiteness OF
the stone overeomes the effect OF the
coarseness Of It's texture. Although this
granite Is remarkably free from iron, its
recent use in large edifices shows that ex-
IRENE care should be exercised in hand

water or other discoloring liquids.

"fhe coarse white granite is a quartz
of slightly Rreenirh white
with conspicuous brilliant white mica
spots up to 0.5 inch across and with field
spars up to O.5 inch. The mica spots be-
ing collections of mica scales have pc
culiar sheen. As they are not over 0.04
inch thick and lie with their fiat sides
roughly parallel, the rock has a somewhat
gneissoid texture. Its constituents in de-
scending order OF abundance are:--Milk-
white to slightly greenish soda-lime field
spar, somewhat kaolinized, with white
mica scales and not a few plates of cal
cite; clear colorless to pale blush quartz,
rarely with hairlike crystals OF rutile, and
with fiuidal and other cavities in two rec
angular sets OF sheets, one set with many
more cavities than the other.
at is building granite OF very pale
yreenish-gray color, with striking con-
rasts produced by large mica spots, the
1rilliancy OF which on the fresh rift face

nearly ~ per cent OF lime carbonate are
