[27] The first letter from the Commissioners to Jonathan Williams, dated Apr. 13, 1778, simply asked him to abstain from any further purchases as naval agent, and to close his accounts for the present. It was not until May 25, 1778, that a letter was addressed to him by the Commissioners expressly revoking his authority as naval agent on the ground that Congress had authorized William Lee to superintend the commercial affairs of America in general, and he had appointed M. Schweighauser, a German merchant, as the person to look after all the maritime and commercial interests of America in the Nantes district. In signing the letter, Franklin took care to see that this clause was inserted: "It is not from any prejudice to you, Mr. Williams, for whom we have a great respect and esteem, but merely from a desire to save the public money, to prevent the clashing of claims and interests, and to avoid confusion and delays, that we have taken this step." The result was that, instead of the uniform commission of two per cent., charged by Williams for transacting the business of the naval agency, Schweighauser, whose clerk was Ludlow Lee, a nephew of Arthur Lee, charged as much as five per cent. on the simple delivery of tobacco to the farmers-general. Later Williams, who was an expert accountant, was restored to the position which he had really filled with blameless integrity and efficiency. After his return to America, his career was an eminent one. He is termed by General George W. Cullum in his work on the campaigns and engineers of the War of 1812-15 the father of the Engineer Service of the United States. In the same work, General Cullum also speaks of his "noble character." [28] In sending a MS. to Edward Everett, which he placed in the library of the Massachusetts Historical Society, Thomas Carlyle said: "The poor manuscript is an old Tithes-Book of the parish of Ecton, in Northamptonshire, from about 1640 to 1700, and contains, I perceive, various scattered faint indications of the civil war time, which are not without interest; but the thing which should raise it above all tithe-books yet heard of is, that it contains actual notices, in that fashion, of the ancestors of Benjamin Franklin--blacksmiths in that parish! Here they are--their forge-hammers yet going--renting so many 'yard lands' of Northamptonshire Church-soil--keeping so many sheep, etc., etc.,--little conscious that one of the demi-gods was about to proceed out of them."
