The finding of tools, in old pits, long since abandoned by a race of wort dl’w extinct still continue*. These tools are cf wonderful workmanship, formed of copper, with a temperandhardness scarcely excelled by the best steel tools of to-day. They arc sifnply chisels in the ordinary form, with ham mere of copper, and huge granite hammers which seem to have been made more for the” efficiency of their weight than for their power to resist the action of blows. The presence of charcoal here and there, in tha depths of these abandoned pits, seems to indicate that fire was used in the bottom of the mines to assist in mining or reducing tho ore3, No other evidence, except that of an imperishable nature, is found to show when or by whom these deposits were worked. But that the whole history ofJdicse early operation* should be buried in oblivion ii a matter greatly rogr^tted by all who have had their attention drawn to them. And now, since tbe 6 closest research has failed to bring ft glimmer of light out of this dark, hidden history, it is not at all likely that the world will ever know aught more of it.1
