III., chap. 10, this duty upon exportation was reduced to five shillings the hundredweight.
In the book of rates, according to which the old subsidy was levied, beaver skins were estimated at six shillings and eightpence apiece, and the different subsidies and imposts, which before the year 1722 had been laid upon their importation, amounted to one-fifth part of the rate, or to sixteenpence upon each skin; all of which, except half the old subsidy, amounting only to twopence, was drawn back upon exportation. This duty upon the importation of so important a material of manufacture had been thought too high, and, in the year 1722, the rate was reduced to two shillings and sixpence, which reduced the duty upon importation to sixpence, and of this only one-half was to be drawn back upon exportation. The same successful war put the country most productive of beaver under the dominion of Great Britain, and beaver skins being among the enumerated commodities, their exportation from America was consequently confined to the market of Great Britain. Our manufacturers soon bethought themselves of the advantage which they might make of this circumstance, and in the year 1764, the duty upon the importation of beaver skin was reduced to one penny, but the duty upon exportation was raised to sevenpence each skin, without any drawback of the duty upon importation. By the same law, a duty of eighteenpence the pound was imposed upon the exportation of beaver wool or wombs, without making any alteration in the duty upon the importation of that commodity, which when imported by British and in British shipping, amounted at that time to between fourpence and fivepence the piece.
