of a bushel foreign salt. Two bushels are the supposed average of Scotch salt. If the herrings are entered for exportation, no part of this duty is paid up; if entered for home consumption, whether the herrings were cured with foreign or with Scotch salt, only one shilling the barrel is paid up. It was the old Scotch duty upon a bushel of salt, the quantity which, at a low estimation, had been supposed necessary for curing a barrel of herrings.

In Scotland, foreign salt is very little used for any other purpose but the curing of fish. But from the 5th April 1771 to the 5th April 1782, the quantity of foreign salt imported amounted to 936,974 bushels, at eighty-four pounds the bushel: the quantity of Scotch salt, delivered from the works to the fish-curers, to no more than 168,226, at fifty-six pounds the bushel only.
