The voice of the people has made itself heard from all parts. The Provinces having successively sent their resolutions here annexed to the Generality, the 19th of April was the great day when the unanimous resolution of their High Mightinesses was adopted to admit Mr Adams; and on the 20th in the morning he went to present his letters of credence to the President of the week. On Monday, at nine o'clock in the morning, I went par etiquette to the house of his Excellency, the French Ambassador, to ask of him the hour when Mr Adams should come and impart to him officially his admission, and in the meantime we were to leave our cards at the houses of all the members of the States-General. The visit to the Ambassador was made in form, and publicly returned in the same way. That of the Envoy of Spain, not requiring the same ceremonial as the rank of the Ambassador, we had given him notice on Sunday evening in a familiar visit, under a condition previously agreed, that he would return it in like manner the next day; and he kept his word. Monday, the 22d, I went to ask audience for Mr Adams, of his Serene Highness, the Stadtholder, who granted it immediately. We dined on Tuesday, the 23d, with the French Ambassador, who had invited all the Corps Diplomatique, and they all attended. Wednesday morning we made the tour of the cities of Holland at their hotels with cards. We left also cards of notification at the hotels of the Ministers of foreign neutral Courts, who probably have written to their Courts to know if they should return the visit. There has been no return of it but from the Minister of Liege. The same morning I went to ask audience for Mr Adams of her Royal Highness the Princess of Orange, which immediately took place.

Monday, 6th of May. Mr Adams was present at a breakfast with M. Boreel, Deputy of the States-General, where he had been invited with all the Court and the Corps Diplomatique.

An address having been presented on Monday, the 22d, to Mr Adams, by six Deputies of the body of merchants of Schiedam, having at their head the Secretary of the city, who invited him at the same time to a grand festival, which they wished to give him, I had the happiness yesterday to excuse him from this festival without dissatisfying these gentlemen, as you will see by the copy of my verbal message to the Secretary.

Add to all this, Sir, the confusion of our removal into the Hotel of the United States of America, which is not yet over, and will not be for several weeks, and you may well have some indulgence for the imperfection of my present correspondence.

Sunday last, after dinner, at the request of the French Ambassador and of our friends here, and with the consent of Mr Adams, I made a journey by post to Amsterdam, charged with a secret commission relating to a concert of operations in this country, which the Anglomanes appeared willing to trouble by some intrigue, and I returned the next day. All is now settled to the satisfaction of France; and the Anglomanes are frustrated.

Day before yesterday we were again at a familiar and friendly dinner at the house of the French Ambassador, with whom Mr Adams was very much satisfied.

I give you, Sir, only a sort of index, very imperfect, of the principal events, which have passed here lately. I leave to Mr Adams, who presented on Monday, the 22d of April, the sketch of a treaty of amity and commerce to their High Mightinesses, to enlarge. I write from memory, not having been able to keep a journal, still less one of my going and coming, my secret interviews, conferences, and negotiations, which were necessary to prepare and bring about what has been done, and which ought not yet to be trusted to paper. No one has better characterised the truly national revolution, which has taken place here, than the French Ambassador, in saying, that the Dutch nation had avenged itself, with the greatest success, of all the political and other evils, which the English have done them since Cromwell; and the Envoy of Spain, who said to Mr Adams, that he had struck the greatest blow, which had been given in Europe for a long time.

I conclude by recommending, Sir, to your attention and to that of Congress, the copy of a letter which Mr Adams wrote me from Amsterdam the 2d of this month. I have not had a moment of leisure to write the present despatch sooner; nor by consequence to make a prompt use of this letter according to the intention of Mr Adams, and which, nevertheless, interests the United States as much as myself. It surprised and affected me very agreeably, and it was no doubt, his intention so to surprise. You know, Sir, or you may know by the papers of your department, since the end of 1775, the intimate part I have had in political affairs without interruption, in executing faithfully the orders of Congress, unsolicited, but accepted on my part with an ardor, which I am bold to say, has never changed, and which has drawn upon me personally all the enemies, open and concealed, of America, and has cost me and my family great persecutions, mortifications, losses and sacrifices. I should fear, therefore, to weaken the letter, so energetic and so honorable to me, of Mr Adams, (who told me by word of mouth, a few days since, that he was surprised Congress had not before made such a disposition on the subject of my affairs,) if I should add anything more, except that I have never had any other principle in my actions, especially in these six or seven years of faithful and painful labor, than the service of humanity, of the United States, and of their honorable Congress; and if in my last sigh, I could add to this testimony of my conscience the idea of having retained, the esteem and friendship of all your respectable Ministers, both in Europe and America, and especially yours, Sir, which will be very dear to me, and which I pray you to bestow on me, I shall contentedly close my days with the words of Horace in my mouth; non ultima laus est principibus placuisse viris.

I am, with the most sincere respect,

DUMAS.
