concrete aggregate, but quantities also were sold for riprap, railroad ballast,
and filler material. 
 In terms of value, crushed limestone continued to rank second among the
types of stone produced. Compared with 1966, output was greater but value
declined. Production was from two quarries in Sussex County and one in Warren
County. Limestone was sold principally for agricultural stone (agstone),
concrete aggregate, filler material, and livestock feed additive. Some of
the output was captive tonnage used for manufacturing hydrated lime. 
 Granite production totaled 1.3 million tons, 19 percent above the tonnage
of 1966. The average value decreased from $1.96 per ton to $1.94 per ton.
Output, mainly from quarries in Morris, Hunterdon, and 
Sussex Counties, was used primarily as concrete aggregate; quantities also
were sold for riprap and fill. Crushed miscellaneous stone (gneiss) quarried
in Passaic County was used exclusively as concrete aggregate and roadstone,
and decreased in production and value from 1966 levels. No argillite was
produced in Hunterdon County as in previous years. Crushed marble used exclusively
in terrazzo was produced in Warren County. Production of dimension sandstone
quarried in Hunterdon County was about the same as the previous year. Oystershell
from Gloucester County was used in making lime and as poultry grit. 
 Five quarries in the State were cited for their safety record. In National
