 Stone.—Stone production consisted primarily of shell (clam and oyster)
and some anhydrite produced in Winn Parish for use in road surfacing and
concrete. Lacking an adequate supply of stone, Louisiana industries rely
on shell as a substitute. Total output of shell was about 6 percent less
than in 1966. About 75 percent of the shell was crushed for concrete aggregate
and road construction; 
the remainder was used in the manufacture of cement and lime. 
 
 Sulfur.—As a result of demand and increased prices, shipments of Frasch
sulfur were at a record level, exceeding the 1966 total by 5 percent. Louisiana
was the leading sulfur-producing State, however, production remained essentially
the same as in 1966. Most of the mines produced at or near capacity.
