Copper the Most Important
At the census Of 1900 the lead smelt
ing and refining industry was the
NEST important Of the three branches,
and copper was second: but at the
census Of 1905 the positions were
reversed At the later census the
copper industry supplied icS per
cent Of the capital 47.5 per cent Of
the wage earners. and 53.3 per cent OF
the value OF products, while the
lead industry furnished 3S.S per celt
Of the capital 2S.2 per cent Of the
wage aarners, and 4l.2 per cent of
the calue of products. That the
growth of the copper industry has
been greater than the growth OF tire
lead Is partially due to an increase In
the practice Of smelling the dry ores
of the precious metals with copper in
stead of lead ores.
