These changes can be made as each fur

To convey the melted matte from the
revcrbcratory furnaces to the convertcrs.
an electric crane which commands the
lower bay of the building for the whole
length has been put up! This crane has
a capacity of 20 tons.
There are two cunvpltCra. intended
each TO blow tive tons Of matte TO pig
