The above facts are, I think, conclusive. They encourage us not only to introduce as much human labour as possible into the mines, but to extend the scale of operations within, by increase of plant, etc., in full assurance that there is no danger either of the ore itself being exhausted or of silver becoming depreciated. And in advancing these views I am merely following a precedent set me by the state herself. So it seems to me, since the state permits any foreigner who desires it to undertake mining operations on a footing of equality[9] with her own citizens.
