means let tie duty be increased on foreign
zinc.
Memorial 10 Congress for an increase Of
tie duty on imported zinc
Several new branches of home industry
have sprung up since the advance in
prices during our domestic war and the
staying out Of foreign importation, which,
if properly protected, will soon become Of
great Importance to the country and aid
considerably in Offering inducements for
other branches Of industry, as we'll rs
aid in paying taxes.
Among these the manufacture Of metal
lie zine or "Spclter' is to cur State the
most important.
Previous 10 1850 the United States i'm
ported all their metallic zinc, which
amounted 10 Mt least one million dollars
annually, and although Wisconsin, and
especially the so called lead regions,
was known to be rich with zine ore Of all
kinds, yet 10 practical use could be made
Of them for the following reasons:
/ lSt. Because the production Of zine re
qurcs much more annual labor than the
manufacture OF any other metal, since it is
impossible 70 extract metallic zine in a fluid
state, bat only in vaporous form, from
the ore, that IS ly = process Of distiIIotion,
Whereby only q small quantity Of the
metal as compared to other metallic pros
.esses i gained.
% The zinc burns to an Oxide in
common furnace as soon as it frees itself
I.om the ore The distillation can there
fore only be accomplished in fro-proo(
retorts at very elevated temperature in
= hich the vnPors of zine become sub
limatel into drops in passing through con-
densation pipes attached to these retorts,
The making Of these retorts and con-
densation pipes is the mere costly as the
clay has net been found in the neighbour
hood OF the ore region. hat at 4 distance
II over 400 miles. he nature or the
zinc ores in the lead region is such ne
to injure to great extent these retorts
On account Of minute particles Of lead
ore being mixed with it. which causes the
vitriieation Of the retorts IN the fire.
81 As the smelling of the zine ores
can only be accomplished by an indirect
heat, that Is by the heating Of retorts in
the furnace, and not ~ direct contact Of
the FIRE with The ore: therefore u much
larger quantity Of fuel Is required than
would be necessary, ~ almost any other
mctaIlurgical process.
To make one ton Of iron It requires
for example only from y to , tons Of fuel;
in smelling lead the quantity Of fuel is
still less; while for the production Of one
ton Of metallic zinc from to - tons oC
coal are necessary. ami like tho fire clay
it : found only ut a considerable distance
from the ore-whiIe in Europe all the
materials for making metallic zine are
fonnd in the same region with the ore or
1t least only at nominal distance from
each other.
Ia addition to these favorable circum-
stances the European zinc makers also
