866 MINERALS YEARBOOK. 1967 
 
 Commercial production represented about 77 percent of the total tonnage
and 84 percent of the total value. The remainder was produced by, or under
contract for, the State and county highway departments and other governmental
agencies. Approximately 94 percent of the commercial sand and gravel output
was transported by truck, and the remainder by rail. Average value for sand
and gravel produced in 1967 was $0.77 per ton, an increase of $0.03 per ton
from that of 1966. About 89 percent of the total sand and gravel output was
processed; the remainder was pit-run material. 
 
 Stone.—Stone production (consisting of basalt, granite, limestone,
marl, quartzite, and sandstone) was 17.1 million tons, valued at $24.9 million,
exceeding the previous tonnage record set in 1960 and the value record established
in 1959. Production increased 6 percent in quantity and 5 percent in value
over that of 1966. Major reason for the increase was greater demand for crushed
and broken stone for concrete aggregate and roadstone. Stone ranked second
in value among the mineral commodities produced in the S ate, accounting
for 31 percent of the total value. Crushed and broken stone accounted for
99 percent in quantity and 85 percent in value of the total stone output
with pro- 
duction increasing 6 percent in quantity and 8 percent in value. About 94
percent of the total crushed and broken stone was produced by commercial
operators. Of this amount, 92 percent was transported by truck and the remainder
by rail. 
 Production of crushed and broken limestone was reported from 39 counties.
Production in 1967 was 14.7 million tons valued at $16.7 million, representing
86 percent in quantity and 79 percent in value of the total crushed and broken
stone output. About 91 percent of the total output was used for concrete
aggregate and roadstone, about the same proportion as in 1966. Output of
agricultural limestone decreased approximately 13 percent in quantity from
that of 1966, and comprised about 6 percent of the total crushed and broken
limestone output. Other uses for crushed and broken limestone, in decreasing
order of quantity, included barnlime, lime manufacture, riprap, railroad
ballast, asphalt filler, flux, fertilizer, and rockflll. Average value of
crushed and broken limestone was $1.14 compared with $1.12 in 1966. 
 About 850,000 tons of crushed and broken granite, used for roadstone, was
produced in Marathon and Wood Counties. Crushed and broken quartzite was
produced in Marathon and Sauk Counties.
