Mineral production in New Hampshire 
in 1967 was valued at $8.1 million, a 16percent increase over the 1966 figure;
the previous record was $7.7 million in 1965. The increased value and volume
were attributed primarily to greater demand for sand, gravel, and stone in
highway con- 
struction, and increased demand for specific types of stone for building
construction. Minerals used in construction continued to dominate production,
~ccounting for over 95 percent of the total value of mineral output in the
State.
