 Spiegeleisen was manufactured at the following plants during 1941:

Carnegie-Illinois Steel Corporation, Duquesne and Clairton, Pa., and Gary,
md.
New Jersey Zinc Co., Palmerton, Pa.
Sloss-Sheffield Steel & Iron Co., North Birmingham, Ala.

 Most of the spiegeleisen produced in the United States is made from domestic
raw materials. However, 1,683 tons of Brazilian ore containing 42.14 percent
manganese and 143 tons of Cuban ore con-. taming 50.73 percent manganese
were consumed in the production of spiegeleisen during 1941. Imports of spiegeleisen
for consumption in 1941 decreased 73 percent from 1940. The total supply
came from Canada.

 The prices of spiegeleisen (20 percent) at producers' furnaces, as quoted
by Steel, remained constant at $36.00 a ton throughout 1941.
 Manganiferous pig iron.—Precise data on the consumption of manganiferous
ores in the production of manganiferous pig iron are not available. However,
820,290 long tons of domestic ore containing 5 to 10 percent manganese and
1,592,700 tons containing 2 tO 5 percent manganese were shipped during 1941.
A small amount of foreign manganiferous iron ore (2,022 tons) and 7,422 tons
of foreign ferruginous manganese ore were also consumed in the manufacture
of pig iron.
