At present, Our Tanners find a great Scarcity of Bark, except those residing in some considerable Sea-Port-Town, and are under just Apprehensions of a greater. Several in the Country have been obliged to lay aside their Pits, and take to other Imployments; the usual Supplies failing. Our Neighbours who will permit any Bark, to be sent us, are in a Manner exhausted. Our _American_ Plantations are too remote to find their Account, in sending any great Quantity. The Produce of our Country is scarce a twentieth Part of what is used in Tanning. This renders our Tannage dear, and often imperfect, so as not to serve a foreign Market, to Advantage, and Reputation. But if we had Materials, of our own Growth, easy of Acquisition, and Propagation, that would tan, in every Respect, as well as Bark; were these Materials, as to their Powers, well ascertain’d, and confirm’d by a general Experience, the making an Act, to prohibit the Exportation of Green Hydes, would be judged by all to be Adviseable, and Useful to the Kingdom. When the apparent Qualities of Bark, are considered; and that by it’s insinuating into the Pores, and incorporating with the Substance of the Hyde, it produces a Firmness, Strength, and Consolidation of the Parts; It is very surprizing, that other Materials, of the same Apparent Qualities, have so long remained neglected, and unapplied to the same Uses; when the Consequence is of such Moment. _Tormentil_, and _Cinquefoil_ Roots, are ranged in the same Medical Class; have the same apparent Qualities, especially the first, in a more eminent, and evident Degree, than Bark, it self. On Tryal, they have answered beyond Expectation: The _Cinquefoil_ did not give so good a Colour, as the _Tormentil_, which in all Respects, as to Colour, Bloom, Substance, Solidity, and Weight, in the Tanned Hyde, compleatly answered, and in much less Time, than when Bark, (even of the best Kind, or Growth) is used.
