“The Secretary of the United States of America for the Department of foreign affaires, His Excellency John Jay to whom was referred a letter to him from the Honourable John Adams of the 27th. of June last, informing that the Queen of Portugal had ordered her squadron in the straits to protect the Vessels of the United States equally, with those of her own Subjects; on the 25th. day of January last reported, that in his opinion, as this is a particular mark of her majesty’s friendly disposition, it should be acknowledged in the manner most likely to be pleasing and acceptable. He therefore thought it would be proper for Congress to write her a letter of the following tenor—
Great and good friend—
We take the earliest opportunity, since our annual election, of presenting to your majesty our sincere Acknowledgements, for the friendly regard you have manifested for us, in having ordered your squadron in the straits to protect our Vessels equally with those of Portugal—Permit us to assure you that we shall retain this mark of generous attention in grateful Remembrance, and shall omit no opportunity of testifying our desire to establish & perpetuate between our two Countries, an intercourse of Commerce and good offices—which may prove no less beneficial than agreable to both.
We pray God to bless and preserve your majesty.
Done by the Congress of the United States convened at the city of New York the —— day of —— 1787.
As this Communication was made by the Queens Envoy, in London to Mr. Adams their secretary thought this letter should be transmitted to him, and that the Compliment would be more delicate if his Secretary was commissioned to carry & deliver it.—
The United States in Congress assembled on the third day of February 1787 ordered the report of the Secretary of foreign affairs, dated 25th. January 1787 on a Letter of 27th. June last from Mr. Adams, be referred to the said Secretary to take order for the transmission of the Letter to the Queen of Portugal, when signed by the President, in the manner suggested in said Report.
These therefore, are to authorise and require, you in pursuance of the instructions of Congress to proceed to Portugal and deliver their Letter, herewith presented to you, to Her Faithfull Majesty, either with your hand, in an Audience to be obtained for that purpose, or by the hand of her Majesty’s Minister of State for foreign affairs as you shall find upon inquiry to be most proper
You are first to consult with Her Majesty’s minister of State for foreign affairs, deliver him a Copy of this Commission, which contains a Copy of the Letter of Congress to Her Majesty, and follow his advice, concerning the manner of delivering it—Done at Grosvenor square, in London this eleventh day of April. A. D. 1787.
(Signed) John Adams
