Year: 1681

page_text: RANCIS
RESUE, Esquire, a native of France,
haveing made a proposall vnto vs for carrying on "A NEW INVENCON OF MAKEING
SALT," within our Kingdomes of England and Ireland, (which as he suggests)
will not onely be of great vse to our subiects in the salting of fish and flesh
without being beholden to other parts, but produce a beneficiall trade between
our Dominions and the Kingdome of Sweeden, and other Norther Countryes,
whether such quantities of salt may be carryed from hence as will passe in
exchange for copper, iron, and hemp, and other commodities whereof our
subiects stand in daily need; and the said Francis Fandell Du Fresue haveing
likewise humbly prayed our Letters Patents granting him such priviledges as
in the case of new invenčons the law directs, by virtue whereof wee may raise
such workes as shall be necessary for the prepareing his salt, and that he and
his associates may enioy the same advantages and immunities in relačon to
our customes as our naturall borne subiects doe, we referred the consideracon
hereof to the Lords of the Committee for Trade and Forreigne Plantacons, whoe
have informed vs that they have conferred with the said Francis Fandell Du
concerning his proposalls, and doe report that vpon full consideračon thereof
the doe not see any reason why wee may not grant him our Letters Patents
for the said new Invenčon, which being rendred effectual by him will cer

page_text: tainely prove of very great advantage to vs and our dominions; and in case it
shall not happen to succeed, appeares to be of noe detriment to vs, the proposer
vndertakeing the whole businesse at his owne charge, without any kinde of
allowance or advance from vs, being willing to rely vpon the strength of our
grant for the performance thereof according to law, which report wee have into
consideracon, and alsoe fully heard the severall objeccons made against the
said intended Patent by by severall owners of salt workes in this kingdome,
and their councell learned, and find noe sufficient grounds for receeding from
the opinion of the said Lords of the Committee: And whereas the said Francis
Fandel Du Fresue hath nõiated Edward Mayo, of our City of London,

said Letters may be granted.
