Last evening Mr Hartley spent two hours with me, and appeared much chagrined at the proclamation, which had never been communicated to him by his principals. He has too much contempt of the commercial abilities of the French, and, consequently said, that the French could derive but little benefit from this step of his Court, but he thought the Dutch would make a great advantage of it. I endeavored to discover from him, whether he suspected that his Court had any hand in stirring up the two Imperial Courts to make war upon the Turks. I asked him what was the state of their Mediterranean trade, and Levant trade. He said, it was dead, and that their Turkey Company was dead, and, therefore, he did not think his Court cared much about either, or would ever do anything to prevent the Empires. He thought it possible, that they might rather encourage them. I am quite of Mr Hartley's mind, that the Dutch will profit by all the English blunders in regulating the West India trade, and am happy that M. Van Berckel will be soon with Congress, when its members and Ministers may communicate through him anything they wish to their High Mightinesses. They may inquire of him what are the rights of the East and West India Companies? To what an extent our vessels may be admitted to Surinam, Curaçoa, Demerara, Essequibo, Berbice, St Eustatia? What we may be allowed to carry there? and what bring from thence to the United States, or to Europe? Whether we may carry sugars, &c. to Amsterdam, Rotterdam, &c.? There are at Rotterdam and Amsterdam one hundred and twentyseven or eight refineries of sugar. How far these may be affected, &c.? I lay it down for a rule, that the nation which shall allow us the most perfect liberty to trade with her Colonies, whether it be France, England, Spain, or Holland, will see her Colonies flourish above all others, and will draw proportionally our trade to themselves; and I rely upon it, the Dutch will have sagacity to see it, and as they are more attentive to mercantile profit, than to a military marine, I have great hopes from their friendship. As there will be an interval before the signature of the definitive treaty, I propose a journey of three weeks, to Amsterdam and the Hague, in hopes of learning in more detail the intentions of the Dutch in this respect. I am in hopes too of encouraging the loan to assist our Superintendent of Finance. The Dutch may be a great resource to us in finance and commerce. I wish that cargoes of produce may be hastened to Amsterdam to Messrs Willinks & Co. for this will give vigor to the loan, and all the money we can prevent England and the two Empires from obtaining in Holland, will not only be nerves for us, but, perhaps, be useful too to France in her negotiations.
