RC (DLC); at foot of text: “Thomas Jefferson Esqr President of the United States”; endorsed by TJ as received 2 Aug. and so recorded in SJL. FC (Lb in DNA: RG 28, LPG). Enclosures: (1) William C. C. Claiborne to Granger, New Orleans, 17 June, enclosing a map (not found) by Barthélemy Lafon marking out a mail route from New Orleans overland “along the Canal of Carondelet, the Bayou Gentilli, the Chemin du Chef Menteur to the River of that name,” thence “by water through the Bayou and Lake Catherine across the Rigolets and then either up one of the Branches of the Pearl River to the residence of Mr. Favre, or along another one to a place marked on the Map Boisdore,” or at a point “a little to the West … where once stood the village Marangoin, and from whence there is an old Indian Road leading through the Pine Woods in a Northern direction”; from the latter place, Lafon estimates the distance to Fort Stoddert is 130 miles; if the water route is objectionable, Lafon suggests a land passage from “the River Chef Menteur … through the Ile Aux Pins and the Island at the Mouth of the Marongoin to Boisdore” could be opened for $3,500 (Rowland, Claiborne Letter Books description begins Dunbar Rowland, ed., The Official Letter Books of W.
