Note 4 — Chapter I

“Cobos.”—This was a duty of one and a half per cent. on the metals extracted from the mines. Its origin, as we are informed, was a grant to this amount, made by the Spanish government in favour of an individual of the name of Cobo. This became a permanent tax which, like the tithes of the metals, afterwards fell into the hands of the government, until both were abolished a few years ago, as alluded to in the text.
