740 MINERALS YEARBOOK

 In years of normal business activity, the quantity of ground sp~~lr produced
from domestic crude has averaged about 87 percent of the crude-spar output;
the remaining 13 percent includes spar used for purposes not requiring fine
grinding and that lost or discarded during the grinding process. In 1931,
however, sales .of ground spar were only about 80 percent of the crude output,
indicating that a considerable tonnage of crude spar must have been added
to stocks. During 1932 part of the tonnage that had been added to stocks
in 1931 apparently was withdrawn as the sales of ground spar represented
nearly 89 percent of the production of crude feldspar.
 Crude feldspar.—Crude feldspar sold or used by producers in the United
States in 1932 amounted to 104,715 long tons, valued at $539,641, a decrease
of 28.8 percent in quantity and 37.3 percent in value compared with 1931.
The average value of crude feldspar in 1932 at the mine or the nearest shipping
point was $5.15 a long ton, or 70 cents lower than in 1931, $1.06 lower than
in 1930, and $2.50 lower than the peak in 1926. The average value for crude
feldspar as reported by individual producers ranged from $2 to $12.88 a long
ton. For New England the value ranged from $2 to $9.13; for New York, Pennsylvania,
and Virginia, from $3.84 to $10.64; for North Carolina, from $4.26 to $6.12;
and for the Western States, from $2.64 to $7.78.

 Crude feldspar was produced in 14 States in 1932, 1 more than in 1931. Maryland,
which reported no production in 1931, reentered the list of producers in
1932 with a small output. North Carolina remained by far the most important
producer with an output of 58,465 tons, 56 percent of the total. New Hampshire
with 8,718 tons held second place, and Maine with 8,345 tons ranked third.
The other producing States, arranged in order of importance, were Virginia,
New York, South Dakota, Colorado, California, Arizona, Connecticut, ~Minnesota,
Maryland, Nevada, and Pennsylvania.
 The decline in production during 1932 was shared by all of the important
producing States, but some of the minor producers reported substantial gains.
In Colorado, for example, the output practically doubled, while production
in Nevada advanced 25 percent. Smaller gains were also reported by producers
in Arizona and New York. The greatest declines in production in 1932 were
reported by Pennsylvania, Minnesota, and California. In North Carolina production
during the year was 32 percent below the 1931 level.
