The table conveys IN a striking manner
the prominence OF the mining lndustIy s,IS.
In the United States. The total quantity
of crude metallic ore from domestic mines
! IN 1912 increased over 25,0Oo,000 short
tons compared with that Of 1911. The

Most of tho ore shipped was hema tite
iron ore from the Lake Superior region:
Brown ore furnished only about per cent
and magnetic less than per cent OF the
ore shipments. Manganese ores OF nigh
grade came mainly from Virginia and the

Arkansas and Virginia, while all the chro-

The figures for aluminium ore given In
the table represent the domestic output
OF bauxIte, mainly from Arkansas, Ala

The figures given for gold ore include
siIiceous, pyfitic, and other alloys in which
the predominant value Is gold. =
The production of silver ore sfven is
mainly that of silver-gold ores in which
the value of the silver exceeds that OF
