Why it is more than double the tithe.

So much for the assistance rendered to the growers of corn.
Every description of agricultural produce pays a tax on export.

There are governments which give a premium to exporters: one may call that encouraging the national industry.

There are others, and they are still more numerous, which allow a free export of the surplus produce of the land: this is not merely to encourage, it is to assist the labourers.

The Pope levies an average tax of 22 per thousand on the total amount of exports, 160 per thousand on the value of imports.
