This implies that JA had given up his lodgings at Madame Schorn's in the Agterburgwal. During the early months of 1781 he was much on the move between Amsterdam, Leyden, and The Hague, but on 27 April he wrote Edmund Jenings: “I have taken an House on the Keysers Gragt near the Spiegel Straat, and am about becoming a Citizen of Amsterdam—unless their High mightinesses should pronounce me a Rebel, and expel me their Dominions, which I believe they will not be inclined to do” (Adams Papers). The arrangements were made by the new American firm in Amsterdam, Sigourney, Ingraham, & Bromfield, to whom JA wrote a succession of letters from Leyden commissioning them to rent a “large, roomly sic and handsome” house “fit for the Hotel des Etats Unis de L'Amerique,” with detailed directions about furniture, a carriage, servants, and much else (9, 11, 13 April, all letterbook copies, Adams Papers; partly printed in JA, Corr. in the Boston Patriot , p. 426–428). His new house on the Emperor's Canal near the Looking-Glass Street was in keeping with his new status; on 25 Feb. he had received a letter from Pres. Huntington of 1 Jan. enclosing a commission, with full powers and instructions voted by Congress on 29 Dec, as “Commissioner ... to confer, treat, agree and conclude” with the States General of the United Provinces “concerning a treaty of Amity and Commerce” (Adams Papers). His letter of credence, however, denominated him “minister plenipotentiary” (enclosure, dated 1 Jan., in Huntington to JA, 9 Jan. 1781, Adams Papers; see JCC , 18:1204–1217; 19: 17–19) See illustrations of present Keizersgracht No. 529 in this volume.
