806 MINERALS YEARBOOK, 1967 
 
million. Compared with that of 1966, the total value was 3 percent greater,
but this was still 5 percent less than that of the record year 1965. The
output of dimension stone was valued at $13.6 million. Dimension granite
and marble were the principal stone types, followed by dimension slate. Crushed
stone production was valued at $6.9 million. Crushed and broken limestone
accounted for over $4 million of the total. Crushed miscellaneous stone was
likewise significant; lesser values were attached to crushed marble, slate,
and granite. In terms of value, Rutland was the principal producing county,
followed by Washington and Windsor Counties. In terms of tonnage, Windsor
County led the State. 
 As the leading stone type, dimension granite, both rough and dressed, was
quarried and processed for use as monuments and mausoleums. Additional dimension
granite was used for rough construction work and for both rough and dressed
architectural purposes, and for curbing and flagging. Crushed granite was
used for concrete aggregate. and roadstone. Washington County led the State
in production of granite, followed by Orange and Windsor Counties. 
 Rutland County was the leading producer of dressed marble for architectural
and monumental purposes. At West Rutland, dimension stone was cut and dressed
for interior and exterior architectural work and for memorial stone. At Proctor,
Grand Isle County, rough and dressed stone was produced for building purposes
and for monuments. Crushed and broken marble was produced for use as chips,
flagging, and miscellaneous purposes at Rochester, Windsor County. Almost
150,000 tons of crushed and broken marble was produced by the Vermont Highway
Department for use as concrete aggregate and roadstone. 
 The output of dimension slate was in excess of 32,000 tons, valued at $2.4
million. All of the slate production was in Rutland County. Seventeen operators
were active during 1967. Most of the 
dimension slate was used for flagstones, and for electrical, structural,
and sanitary products. Over 4,000 tons of roofing slate was produced, as
well as slate for miscellaneous purposes including blackboards and billiard
table tops. Some crushed and broken slate was expanded for use as lightweight
aggregate. 
 No dimension limestone was produced during 1967. However, 1.2 million tons
of crushed limestone, valued at $4 million, was produced. Rutland County
led in value of output, but Chittenden and Franklin Counties led in production.
At Florence, limestone was produced and crushed for use as aggregate, roadstone,
and for agricultural purposes. At South Wallingford, limestone was quarried
and crushed for use as filler in paints, rubber, flooring, plastics, and
pottery and for miscellaneous purposes. 
 At Colchester, Chittenden County, limestone was produced for concrete aggregate
and roadstone, and at Winooski, a quarry and lime plant were in operation
for the production of agricultural lime and quicklime for use in the paper
industry. At Swanton, Franklin County, crushed limestone was produced for
aggregate, roadstone, quicklime, and a small amount for riprap. 
 The production of miscellaneous stone was in excess of 1 million tons for
use in highway construction. Most of the output was quarried in Windsor County
through contracts with the Vermont Highway Department, and a relatively small
amount was produced in Orleans County. In Bennington and Windsor Counties,
19,000 tons of sandstone was produced, also in Government-and-contractor
operations. 
 
 Talc.—Talc production increased 18 percent in tonnage and 21 percent
in value from that of 1966, the highest levels since 1952. Of the three mines
in operation the largest was in Windsor County, followed by the ones in Lamoille
and Windham Counties. Most of the talc was ground for use in ceramics, foundry
facings, insecticides, paint, paper, roofing, toilet preparations, and other
uses.
