|Sir||London Sepr. 12. 1785.|
Mr. Barclay will deliver you this Letter on his way to Mercco. We have appointed him to this Negotiation, in hopes of obtaining the friendship of all the States of Barbary, to our Country, and of opening by that means the Commerce of the Mediterranean, an object of sufficient importance to induce him to accept the trust.
We recommend him and Colo. Franks who goes with him to your attention and Assistance, & we particularly desire you to interest the Court of Spain in his favor, if you think it practicable. Your Success upon many Occasions with the Spanish Ministers, give us hopes that you may obtain for him, Instructions or Letters to Spanish Consuls or other Gentlemen which may contribute both to the Comfort of his Travels & the Success of his Mission.
Any dispatches for us which he may convey to you, your own just sense of the importance of them will induce you to transmit to Us with all possible Care. We are informed of the friendly attention of the Court of Madrid to the Case of our fellow Citizens lately in Captivity as well as on many other Occasions, and if you think it will not be taken amiss, you will oblige us, by expressing our grateful Sense of it, wherever you think proper; With great Esteem we have the Honor to be Sir / Your most obedient & most humble servants
