It was soon reduced therefore to a third; then to a fifth; afterward to a tenth; and at last to a twentieth part of the gross produce of the gold mines. The tax upon silver continued for a long time to be a fifth of the gross produce. It was reduced to a tenth only in the course of the present century.
