399The Mineral Industry 
of Massachusetts 
By Melvin E. Hinlde1 
 
 
 Massachusetts mineral production rose to a new high of $40.6 million, a
6— percent increase over the previous high set in 1966. The increase
resulted mainly from the greater value of sand and gravel and stone, which
combined represented 92 percent of t he State total. The value of lime production
increased 12 percent. 
 Middlesex County, with mineral output valued at $12 million or 30 percent
of the State total, continued to retain its lead as the State's chief mineralproducing
county; Berkshire County remained second with a mineral output value of $7.7
million.
