But he is widely mistaken both in the quantity exported and in the value.

In 1349, the parliament remonstrate, that the king, by an illegal imposition of forty shillings on each sack exported, had levied sixty thousand pounds a year:[*] which reduces the annual exports to thirty thousand sacks.

A sack contained twenty-six stone, and each stone fourteen pounds;[**] and at a medium was not valued at above five pounds a sack,[***] that is, fourteen or fifteen pounds of our present money.
Knyghton's computation raises it to sixty pounds, which is near four times the present price of wool in England.
