Paris Dec: 27. 1785
Your favors of the 13th. & 20th. were put into my hands today. this will be delivered you by mr[expansion sign] Dalrymple, secretary to the legation of mr[expansion sign] Crawfurd. I do not know whether you were acquainted with him here. he is a young man of learning & candor, and exhibits a phaenomenon I never before met with, that is, a republican born on the North side of the Tweed.
You have been consulted in the case of the Chevalr. de Mezieres nephew to Genl. Oglethorpe, and are understood to have given an opinion derogatory of our treaty with France. I was also consulted, and understood in the same way. I was of opinion the Chevalier had no right to the estate, & as he had determined the treaty gave him a right, I suppose he made the inference for me that the treaty was of no weight. the Count de Vergennes mentioned it to me in such a manner that I found it was necessary to explain the case to him, & shew him that the treaty had nothing to do with it. I inclose you a copy of the explanation I delivered him.
Mr. Boylston sold his cargo to an Agent of Monsieur Sangrain. he got for it 55. livres the hundred weight. I do not think that his being joined to a company here would contribute to it’s success. His capital is not wanting. Le Couteux has agreed that the Merchants of Boston sending whale oil here, may draw on him for a certain proportion of money, only giving such a time in their draughts as will admit the actual arrival of the oil into a port of France for his security. upon these draughts  they will be able to raise money to make their purchases in America.—the duty is 7H-10 on the barrel of 520[TJ pound sign] French, and 10. sous on every livre, which raises it to 11H-5, the sum I mentioned to you. France uses between 5. & 6. millions of pounds weight French, which is between 3. & 4000 tons English. their own fisheries do not furnish one million & there is no probability of  improving. Sangrain purchases himself upwards of a million. he tells me our oil is better than the Dutch or English, because we make it fresh, whereas they cut up the whale & bring it home to be made, so that it is by that time entered into fermentation. mr[expansion sign] Barrett says that 50. livres the hundred weight will pay the prime cost & duties & leave a profit of 16. per cent to the merchant. I hope that England will within a year or two be obliged to come here to buy whale oil for her lamps.
I like as little as you do to have the gift of appointments. I hope Congress will not transfer the appointment of their Consuls to their ministers. but if they do, Portugal is more naturally under the superintendance of the minister at Madrid, & still more naturally  the minister at Lisbon, where it is clear they ought to have one. if all my hopes fail, the letters of Govr. Bowdoin & Cushing, in favor of young mr[expansion sign] Warren, & your more detailed testimony in his favor, are not likely to be opposed by evidence of equal weight in favor of any other. I think with you too that it is for the public interest to encourage sacrifices & services by rewarding them, and that they should weigh to a certain point in the decision between candidates.
I am sorry for the illness of the Chevalr. Pinto. I think that treaty important: & the moment to urge it is that of a treaty between France & England.
Lamb, who left this place the 6th. of Nov. was at Madrid the 10th. of this month. since his departure mr[expansion sign] Barclay has discovered that no copies of the full powers were furnished to himself, nor of course to Lamb. Colo. Franks has prepared copies which I will endeavor to get to send by this conveiance for your attestation: which you will be so good as to send back by the first safe conveiance & I will forward them. mr[expansion sign] Barclay & Franks being at this moment at St. Germain’s, I am not sure of getting the papers in time to go by mr[expansion sign] Dalrymple. in that case I will send them by mr[expansion sign] Bingham.
Be so good as to present me affectionately to mrs[expansion sign] & miss Adams, to Colos. Smith & Humphries & accept assurances of the esteem with which I am Dear Sir / Your friend & servt.
P.S. be pleased to forward the inclosed, sealing that to Congress after you have read it.
