 North Carolina led in the output of ground spar as in that of crude spar
by a wide margin. Tennessee held second place, and New York ranked third.
These three States together accounted for two thirds of the ground feldspar
produced in 1932. The remaining third was accounted for chiefly by Maine,
Virginia, New Jersey, South Dakota, Colorado, New Hampshire, California,
and Arizona. Comparatively small tonnages of ground spar were milled in Ohio,
Minnesota, and Illinois in 1932.
 During 1932 the production of ground feldspar in Colorado and Arizona showed
substantial gains over that in 1931, while a small increase was reported
for Tennessee. However, the increases in these* States failed to offset the
heavy losses elsewhere. In North Carolina production decreased 22 percent
below that in 1931, and even more severe declines were reported by many other
producing States. The most pronounced decline occurred in Ohio, where the
production of ground spar in 1932 was 71 percent less than in 1931.
