The date of Abraham’s report and the means by which it came to TJ are uncertain, although it likely was prepared and received sometime during the summer of 1805. Abraham received his contract to carry the mail between Coweta and New Orleans in March. Details of his subsequent activities are sparse. He likely gathered the information reported above by early July. Writing to Madison on 5 July, William C. C. Claiborne stated that Abraham had been to New Orleans twice, reporting that the road between Fort Stoddert and New Orleans was “difficult and often interrupted by High Waters” (Madison, Papers, Sec. of State Ser. description begins William T. Hutchinson, Robert A. Rutland, J. C. A. Stagg, and others, eds., The Papers of James Madison, Chicago and Charlottesville, 1962– : Sec. of State Ser., Pres. Ser., Ret. Ser. description ends , 10:25). Gideon Granger, however, reported receiving only two communications from Abraham, dated 25 May and 25 June, the latter of which was sent from Fort Stoddert. Neither has been found (see Granger to TJ, 19 July, 19 Aug.). Abraham Bradley, Jr., sent TJ two unidentified letters by Abraham on 28 Aug., but TJ apparently returned these to Bradley on the 31st.

Bradley recorded the Distances between the waterways described by Abraham on the verso of an undated printed broadside that is now in TJ’s papers titled “List of Stages On the new Post-Road from Washington City to N. Orleans.” According to Bradley’s list, the distance from Fort Stoddert to Dog River was 25 miles; thence to Pascagoula River, 35 miles; thence to Bogue “Lucer” (Black Creek), 19 miles; thence to Bogue “Houma” (Red Creek), 10 miles; thence to St. Peter’s (“Ste Petre”) Creek, 20 miles; thence to Hammock River, 15 miles; thence to Log Creek (not mentioned by Abraham), 8 miles; thence to Wolf River, 12 miles; thence to Catahoula Creek, 12 miles; and thence to Favre’s Bluff on the Pearl River, 12 miles. Bradley also noted the width of the waterways and provided a brief physical description of each (DLC: TJ Papers, 234:41846). Granger incorporated much of the information provided by Abraham and recorded by Bradley in a 21 Mch. 1806 message to the House of Representatives regarding obstructions on the postal route between Athens, Georgia, and New Orleans (ASP description begins American State Papers: Documents, Legislative and Executive, of the Congress of the United States, Washington, D.C., 1832-61, 38 vols. description ends , Post Office Department, 1:39-40; JHR description begins Journal of the House of Representatives of the United States, Washington, D.C., 1826, 9 vols. description ends , 5:321).
