402 
MINERALS YEARBOOK, 1967 
 
 Lime.—Production and value of lime increased1 7 and 12 percent, respectively,
over that for 1966. The chemical industry consumed 79 percent of the total
output with the remainder used in agriculture and the building industries.
Berkshire County was the only county in the State to produce lime; three
companies produced quicklime and hydrated lime from local limestone. 
 
 Perlite (Expanded).—Crude perlite mined ' outside the State was expanded
at two plants in Suffolk County that sold the product mainly for use as a
lightweight aggregate, as a soil conditioner, and as cryogenic insulation.

 Sand and Gravel.—Greater activity in highway and building construction
resulted in a higher output and value of sand and gravel over that of 1966.
The value of sand and gravel, output, $19.5 million, accounted for 48 percent
of the total mineral value in the State, making it the leading mineral commodity
produced. Gravel accounted for 61 percent of the 17.9 million tons of sand
and gravel produced. Close to 82 percent of the total tonnage was mined at
commercial operations; 
 
contractor operations balance.
