1. First entry in D/JA/32, a pocket memorandum book with a cover of Dutch decorated paper over boards which have loops for a pencil at the fore-edge. Most of the entries are in pencil, and most of them are undated, but all belong to JA’s first months in the Netherlands. Inside the front cover is a notation, probably in the hand of Harriet Welsh, a relative who lived in Boston and who acted occasionally as JA’s amanuensis during his old age: “The Dutch book of Mr. John Adams when in Holland in the revolution. June 1823.” Among the leaves left blank by JA in the middle of the book are six scattered pages of accounts which are in a hand not even tentatively identified but unquestionably later than 1800. These have been disregarded in the present text. Since this is not a diary in the conventional sense, but a pocket engagement and address book containing occasional diary-like entries, CFA included nothing from it in his edition of JA’s Diary. Yet the contents, fragmentary and sometimes cryptic as they are, throw some light on the beginnings of JA’s mission to the Netherlands.

From JQA’s Diary we learn that the Adamses left Rotterdam on 7 Aug. by canal boat for Delft and went on to The Hague, where JA consulted with the American agent, Charles William Frederic Dumas, and the French ambassador, the Due de La Vauguyon. They visited Leyden on the 9th, stopping there one night, and proceeded by canal boat via Haarlem to Amsterdam on the 10th, putting up at “l’Hotel des Armes d’Amsterdam.” In this city they found numerous Americans, including Alexander Gillon, who enjoyed the title of commodore of the South Carolina navy (Arthur Middleton to JA, 4 July 1778, Adams Papers). Gillon had Dutch relatives and found lodgings for the Adamses next door to his own (JA, Corr. in the Boston Patriot description begins Correspondence of the Late President Adams. Originally Published in the Boston Patriot. In a Series of Letters, Boston, 1809[–1810]; 10 pts. description ends , p. 345–346). JA at once set about establishing such commercial, political, and journalistic connections as he could.

2. That is, Henrik Hooft, Danielszoon, a burgomaster of strongly republican (anti-Orangist) sentiments, who lived on the Heerengracht (Lords’ Canal) near Vyzelstraat (Johan E. Elias, De vroedschap van Amsterdam, Haarlem, 1903–1905, 2:726).

3. Hendrik Calkoen (1742–1818), later described by JA as “the giant of the law in Amsterdam.” See Nieuw Ned. Biog. Woordenboek description begins P. C. Molhuysen and others, eds., Nieuw Nederlandsche Biografisch Woordenboek, Leyden, 1911–1937; 10 vols. description ends , 3:195–197. Three days later Calkoen addressed a series of questions about the United States and its resources to JA in writing (Adams Papers), to which JA replied in a MS dated 4–27 Oct. 1780 (Adams Papers), afterward printed as Twenty-Six Letters, upon Interesting Subjects, respecting the Revolution of America ..., London, 1786; reprinted New York, 1789. JA included them among his letters to the Boston Patriot, preceded by an explanation of how they came to be written and the use Calkoen made of them to spread “just sentiments of American affairs” in the Netherlands (JA, Corr. in the Boston Patriot description begins Correspondence of the Late President Adams. Originally Published in the Boston Patriot. In a Series of Letters, Boston, 1809[–1810]; 10 pts. description ends , p. 194). CFA also included them, with the explanation, in JA’s Works description begins The Works of John Adams, Second President of the United States: with a Life of the Author, ed. Charles Francis Adams, Boston, 1850–1856; 10 vols. description ends , 7:265–312.

4. Alexander Gillon, of Charleston, S.C., but probably of Dutch origin, had recently acquired a Dutch-built frigate for the use of South Carolina and had named it for that state. He was also attempting to negotiate a loan for his state in Amsterdam and had gone the rounds of the banking and brokerage houses. JA held a respectful opinion of Gillon until after the fiasco of the latter’s voyage of 1781, with CA on board. Gillon started from the Texel for America, but after six weeks put in at La Corufia, Spain, where his American passengers made haste to leave the South Carolina. See D. E. Huger Smith, “Commodore Alexander Gillon and the Frigate South Carolina,” So. Car. Hist. & Geneal. Mag., 9:189–219; John Trumbull, Autobiography, ed. Theodore Sizer, New Haven, 1953, p. 75–77.

5. On 5 Sept. JA developed this idea in a letter to Pres. Huntington proposing the establishment of an “American Accademy, for refining, improving and ascertaining the English Language,” to be maintained by Congress in conjunction with “a Library consisting of a compleat Collection of all Writings concerning Languages of every Sort ancient and modern” (LbC, Adams Papers).
