 Stone.—Total reported value of stone production increased 38 percent
compared with that of 1966. Of the total 1967 value of production, 70 percent
was accounted for by dimension granite, 20 percent by crushed granite and
miscellaneous stone, and 10 percent by crushed quartz. Production and value
of crushed granite and miscellaneous stone remained near the 1966 level,
but increases occurred in dimension granite and crushed quartz. Output of
dimension granite increased 19 
percent in value and nearly 21 percent in volume. Major increases occurred
in curbing and flagging and dressed construction granite. Production and
total value of dimension granite for monuments and architectural uses declined
slightly during the year. Output of crushed quartz in 1967 more than doubled
that of the previous year; total value increased 90 percent. Material was
used primarily as exposed aggregate in decorative concrete.
