Washington, Oct 13.-The stone produced in the
United States may classified broadly granite,
sandstone, limestone and narble-names that are
commercially convenient but by no means scien-
tfcally exact especially regards the rocks known
as GRANTEES Commercial granite includes gneiss.
gabbro. dabase. andeste. syenite and other rocks
Sandstone includes quartzites. on the other hand
certain fine grained sandstones are known TO the
trade as "bluestone.' and some Kentucky sand
stones are marketed "frecstone' The term
.'traprock" is used commercially TO denote certain

in California and the production Of this granite rock
forms an industry so important that its value is
shown separately in the United States Geological
Surveys report the production OF stone IN lSuo

Almost all the producers. especially the small
oyarrvnoen state that the cost Of production was
greater IN 1906 because OF the increase in the cost
of supplies and in the rates Of wages especially foF
common laborers The Increased use of cement ana
concrete has also had important effect on the
stone industry.
Pennsylvania producing chiefly limestone and
sandstone but also granite and marble reported the
greatest value Of stone output for the entire United
states which was 13 81 per cent OF the total Yer
mont producing granite marble and a small guam
titv of limestone, was second, with s134 per cent
Of the total; New York, producing sandstone lime
stone granite and marble, RANKED third: Ohio pro-
aucng limestone and sandstone. was fourth Massa-
chusetts producing granite marble. sandstone ana
limestone was fifth; Indiana, was sixth. followed
nv Illinois Maine California and Missouri each
nroduong stone valued at over s2,000OOO
Massachusetts exceptionally ranked frst among
the granite producing in 1906, its great in
crease being due to large contracts for stone Tor
the new Pennsylvania Railroad station in New
Yor, CITY Pennsylvania led In sandstone and lime
Stone In marble Vermont led followed by Georgia
and Tennessee.
Considered as to uses. the stone produced may be
divided into building monumental, flag, curb paving
and crushed stone the largest value being repre-
sened by building (S2O 6s7,625) and the next
largest (s17 4S7,4Ss) By crushed stone. when is
,,eed principally for railroad ballast, road making
and concrete The production of crushed stone for
use In making concrete showed a great increase, and
the wider - of cement concrete in buildings ana
nayerents I'll doubtless a still larger de-
roand for stone in this form. Limestone Is the
stone most used for this purpose.
